Cover for Winter, 191fl—North Carolina's Capitol, located in the center of a six-acre tract, around which was laid out the City of Raleigh as a State Capital, of Grecian Doric design copied from the Temple of Minerva (The Parthenon) in Athens and with other Grecian and Roman architectural features, was designed and built by David Paton, Scotch architect, who was brought to Raleigh to design and super-vise its construction. Seven years, 1833-1840, were required for its completion, at a total cost of $531,674.46, which was appropriated by seven annual sessions of the General As-sembly. The stone of which it was constructed was quarried within one mile of the Capitol, largely by convict labor, and was hauled to Capitol Square on a narrow-gauge railroad track from the quarry to the Square. The stone is gneiss, particularly suitable for construction of large buildings. "The old rock quarry," long a deep hole caused by quarrying the stone, partially filled with water for 100 years and located south-east of Capitol Square, was finally filled in during the early 1940s. Sent free upon request to responsible individuals, agencies, organizations and libraries. Address: E. S. C. Informational Service, Raleigh, N. C.

QUARTERLY": NEW SSZE Because the recent session of the North Carolina General Assembly changed the name of the "Unem-ployment Compensation Commission of North Caro-lina" to the "Employment Security Commission of North Carolina" and the "Unemployment Compen-sation Law" to the "Employment Security Law," the name of "The U.C.C. Quarterly" is also changed to "The E.S.C. Quarterly." Articles in this issue were written before the change was made, so wherever the initials "U.C.C", or the longer name for which they stand, appear, it means "E.S.C." or Employment Security Commis-sion. With this issue the size of our quarterly changes, but only in one respect—the overall size, which is reduced slightly. Type sizes and type pages remain the same. Only the margins are slightly reduced. N. C. GRANITE PRODUCED IN YEAR 1945 VALUED AT $312,794 "The South, a Leader in Stone Production" is the title of an article written by Oliver Bowles and Rob-ert P. Willing and, with eight illustrations, occupies several pages in the February issue of Manufactur-ers Record, Baltimore, Md. Three of the illustrations are from North Carolina. One is the exterior view of the U. S. gold depository at Fort Knox, Ky., made of Mount Airy granite; another is of a big granite lathe at the Mount Airy plant, turning a round granite post; and the third shows a stack of granite being crushed for highway construction, with the information that four quarries and four plants of one North Carolina company (not identified) produce gravel and crushed stone. For many years, the authors relate, the South has been one of the country's leading stone producers. Figures based on the report of the Minerals Year Book of the Bureau of Mines, the South produced nearly 30 percent of the nation's total in 1945, or 43,999,610 short tons valued at $53,033,607. Pro-duction includes ornamental stone such as that used in Washington's magnificent structures and other dimension stone for building, as well as crushed and broken stone used in lime and cement and highway construction, the article relates. Reference is made to the granite operations at Mount Airy and near Salisbury, the marble develop-ments in Cherokee County and crushed stone activi-ties in many parts of the State. One paragraph in the article reads as follows : "North Carolina also produces considerable quantities of di-mension granite near Mount Airy in Surry County near the northern State boundary. The cut stone produced in this re-gion is widely used in bridges, dry docks and in large build-ings. An extensive market likewise has developed for the smaller fragments—ashlar—for constructing moderate priced homes. Both quarries and mills at Mount Airy are equipped with modern machinery. In addition to Surry County, granite is found in Rowan, Davidson, Wake and Henderson Counties. In 1945 North Carolina produced 13,990 short tons of granite valued at $312,794." WINTER, 1947 THE E. S. C. QUARTERLY PAGE 3 Mount Airy Granite Famous for Buildings and Monuments By M. R. Dunnagan, hifovulational Service Representative, ESC About 75 years ago, one Robert S. Gilmer purchased a large farm in Surry County, on a portion of which part of the Town of Mount Airy is now located. Within the farm area, about two miles from the site of the Town of Mount Airy, was a huge rock forma-tion, known locally as "The Rock," about 50 acres in area and in appearance something like a huge oyster shell. The farm was bought at a "per acre" rate, and, as it was not suitable for farm purposes, "The Rock" was not counted in the acreage, but was given to the purchaser without charge as a part of the farm area. That part of the farm which was then considered worthless is now famous as the largest open-faced granite quarry in the world, with 80 acres of work-able granite exposed. From its surface many thous-ands of tons of granite have been quarried and sold for millions of dollars for use in public buildings, bridges, homes, memorials, and mausoleums in prac-tically every state in the nation. In 1889, while the Cape Fear and Yadkin Valley Railroad was being built from Wilmington to Mount Airy, an English-born family named Woodruff, then living in Greensboro, had the contract for building the railroad stations between Greensboro and Mount Airy. Four sons in this family, William, George, Thomas and Frank, lived in Mount Airy while com-pleting the construction work on that end of the line. Seeing possibilities in "The Rock," whose principal use up to that time was as a location for picnics for the people in the surrounding countryside, these Woodruff brothers purchased it and some of the sur-rounding land from Mr. Gilmer for about $5,000. They set about quarrying the granite immediately upon purchase in 1889, and several years later in 1904, The North Carolina Granite Corporation was formed. Around 1910, John Davis Sargent, an experienced quarryman from Vermont was brought to Mount Airy to operate the quarry. Mr. Sargent soon saw the possibilities of cutting stone for buildings, monu-ments, etc., and leased from the Woodruff brothers the cutting sheds which they had been operating along with the quarry. Mr. Sargent then formed the J. D. Sargent Granite Co. on his own and began cutting the granite into dimension, monumental, and other types of stone. The J. D. Sargent Granite Co. bought the rough granite from the Woodruff's cor-poration, which Mr. Sargent continued to run for them. It was not long before the young cutting company became the largest part of the operation, and having proved itself was taken into the larger corporation with Mr. Sargent as president of the North Carolina Granite Corporation. Note—Information for this article was furnished largely by John P. Frank, president, N. C. Granite Corp., Caleb H. Haynes, Mount Airy, N. C, and from an article published in "Rock Products," McLean-Hunter Pub. Corp., Chi-cago 6, III. Shortly after this Francis H. Fries and W. F. Shaffner, bankers of Winston-Salem, and Charles B. Keesee, a banker in Martinsville, Va. became inter-ested financially in the corporation, and they together with Mr. Sargent formed the "big four" stockhold-ers, after buying out the interests of all other stock-holders, including the Woodruff brothers. Messrs. Fries, Shaffner, and Keesee had come to know of the quarry through dealings, and vacations spent at White Sulphur Springs, near Mount Airy. "BIG FOUR" DEVELOP QUARRY This "big four," sparked by the dynamic Mr. Sar- KILLED GENERAL, LATER SHARPENED TOOLS TO CARVE MONUMENT TO HIM The State of Pennsylvania, during the years after the War Between the States, decided to erect a monument to its illus-trious sons, and gave the contract to the owners of the Mount Airy granite quarry for the stone, the Ionic columns and the heroic statues of the citizens it was to honor. The material was produced and the monument was erected at Gettysburg, com-memorating that famous battle and rising high above the battleground. When most of the figures of noted Pennsylvania men had been completed or were Hearing completion, a resident of Pennsylvania came to North Carolina on other matters. He knew of the plans for the monument and visited the quarry more than once. Taking others to see the work, he pointed out the various distinguished men represented. He pointed to one statue, explaining that it was of General Reynolds, of Pennsylvania, and that he had been killed in the Battle of Gettysburg. "I think it is entirely appropriate," spoke up one of his guests, "for Pennsylvania to have this work done in North Carolina, in Surry County and here at Mount Airy. For it was," he continued, "a Surry County and a Mount Airy man who killed General Reynolds. In fact, the man who killed General Reynolds is the man who is now and has been for some years in charge of making and sharpening the tools with which the statue of General Reynolds was carved." And, as the man who had shot General Reynolds was pointed out, as he went about his forge working on tools used in the quarry, the story was unfolded. It has been picked out of the blacksmith, who previously had operated a blacksmith shop near Dobson, by friends who knew something of the incident. The blacksmith and tool sharpener was so modest that they had to keep picking and questioning to get him to relate what happened. Sharpshooter Frank Wood and Private Cox, it developed, were in the thick of the fight at Gettysburg. In some way they became separated from their company and found themselves in a railroad cut, right in the line of fire. Nearby, they saw a rail fence and ducked to it for protection. From this cover they surveyed the scene. A few hundred yards away they saw on a big horse a man, gold braid on his hat, epauletts on his shoulders, scabbard and boots with spurs and other accoutre-ments speaking of high rank. He was standing up in his stir-rups, waving his sword and shouting to his men. "Give them hell, boys. Give them the grape. Give them hell. Give them the grape." Private Cox asked Sharpshooter Wood if he couldn't pick that man off at that distance. Wood wasn't sure, but thought he could. He estimated the distance, raised the sights on his musket, took deliberate aim, and fired. The man fell from his horse, dead. That was General Reynolds and Sharpshooter Wood, back home and a blacksmith for several years, went with the Mount Airy granite firm to make and sharpen tools, and produced the tools with which the statue of General Reynolds was cut and chiseled and formed. (See picture of Pennsylvania Monu-ment, page 6)—M. R. D. (Information supplied by Caleb H. Haynes, Mount Airy, N. C.) PAGE 4 THE E. S. C. QUARTERLY WINTER, 1947 gent, actually and figuratively, put Mount Airy gran-ite on the map of most states in the Union. Novel methods of advertising and publicizing this granite were promoted by Mr. Sargent and his associates. By-products of the quarry were utilized and many new uses for granite from the screening to dimension blocks were devised and developed. During this time the "big four" would take into the firm promising young men, test them, give them positions of importance and trust, and when they proved their mettle, allow them to purchase stock, or, in some cases, give them stock to increase their interest in the success of the firm. One of these employees was John Prather Frank, son of Methodist missionaries to Japan. Mr. Frank was taught by his parents in Japan. His entire formal schooling included one year in high school at Mount Airy, two years at Trinity Park school on the Trinity College campus, and four years at Duke Uni-versity. He specialized in business administration. After finishing college at 20 years of age, Mr. Frank applied for a job at the quarry, was hired at $15 a week and paid $20 for his second week. He started in the drafting room, worked there about eight months and was transferred to the business office, doing clerical work. After four years Mr. Frank was elected assistant secretary-treasurer of the firm. In 1935 he was pro-moted to secretary-treasurer, in 1940 to vice-presi-dent, and in July, 1945, following the death of Mr. Sargent, was elected president of The North Carolina Granite Corporation. Chris Binder was brought into the business in 1916 by Mr. Sargent, who recognized his ability as a cut stone man. Mr. Binder's experience was gathered from operations in New England, Pennsylvania, and Georgia. It was not long before he became Manager of the Cut Stone Department of the corporation, and has operated that department successfully for the BUILDINGS, BRIDGES, MEMORIALS PRODUCED FROM MT.

Supreme Court, Attorney General, State Bureau of Investigation, Selective Service, National Guard and other offices. the Traphill area of the Elkin-Roaring Gap high-way. Little activity is carried on at this latter site at present. COMPOSITION AND CONDITIONS "The Rock" at Mount Airy still has the appear-ance of a monstrous oyster shell, even though prob-ably 50,000,000 cubic feet of granite have been re-moved. During periods of normal operations about 3,000 carloads are removed each year, yet it is esti-mated that 500 years of quarrying at that rate will not exhaust the supply. The granite surface is still above or even with the surrounding land area—no underground or below surface operations. Mount Airy granite is described as a biotite gran-ite of medium grain, almost white, but with a light grey appearance. The feldspar, principal constitu-ent, is white; the quartz is blue-gray and the small amount of mica is black. All of these parts are even-ly distributed throughout the entire deposit, result-ing in a remarkable uniformity. Tests are interesting. They show that a cubic foot of this granite weighs 165 pounds; that the crushing strength per square inch is 23,069 pounds. They also reveal that the water absorbed by a cubic Well-knotvn Arlington Memorial Bridge, connecting Arlington Cemetery and the City of Washington. Bridge and approaches contain 685 carloads of finished white Mount Airy granite. foot of this granite is only 0.33 of a pound. This means that if 165 pounds of this granite were sub-merged in water, it would absorb less than one-third of a pound of the water. Its crushing strength and water resistant qualities are pointed to as particu-larly desirable in the construction of large buildings and bridges. The average person will be surprised at the sim-plicity of the quarrying processes. Dynamite is never used for quarrying. Results of its use would be disastrous. Its force would shatter and crack the granite, causing flaws in the blocks. Nor is com-pressed air used in the lifting process, although it is used extensively in granite quarrying and cutting. Mother Nature, with her heat expansion in sum-mer and cold contraction in winter, is a most valu-able worker at this quarry. Her chief ally and aide is one of the oldest of explosives, black gunpowder, and this is used sparingly. The splitting quality of the granite aids in the quarrying. The grain of the granite is horizontal and a light force starts a split which gives a smoother surface than is achieved in splitting boards. Also, regular and even force ex-erted through the principle of the wedge gives a smooth and remarkably even perpendicular split. It is the same principle used by the ice man who marks a chunk of ice with his axe, gives a harder stroke and a smooth, even, 50-pound piece of ice separates itself. So, when a sheet of granite is needed for large cut or dimension stone construction, a hole, about 2V-> inches in diameter, is drilled perpendicularly into the granite four to eight feet deep. A small, very small, charge of black powder is placed at the bottom of this hole and exploded. The explosion merely starts a small horizontal crack in all directions from the bottom of the hole. A slightly larger charge of pow-der is exploded, extending this crack or split in the granite. Another slightly larger charge is exploded, extending the split still further, but not damaging the granite. This process is continued until the hori-zontal split is as large as is needed, or it is left for HUGE CUT STONES AND FINE GRIT COME FROM MOUNT AIRY GRANITE The wide range of sizes and wider range of uses for Mount Airy granite is shown in the following list: Cut Stone—Huge blocks, shaped and sculptured, form mauso-leums, monuments and memorials, columns, heroic figures and other decorations for buildings. Dimension Stone—Used in constructing buildings, bridges and other large structures. Paving Blocks—Usually 4y2 x5xl0 inches or size desired, and Street Curbing, usual or unusual sizes. Flagstones—Made from quarry blisters, from one to five inches thick, form artistic, rough natural stones for walkways in gardens, floors of open places and other bases. Rough Ashlar—Suitable for schools and churches, 6x9x4 inches, and larger, ready for use as it comes from the quarry. Rubble—Needs shaping, before use in building walls. Rip-Rap—Odd sizes of quarry refuse, suitable for sea walls, embankments and aggregates for heavy concrete foundations. Crushed Stone—Crushed to various sizes. One machine re-duces granite to 2% inches or down to one inch, screened for size. Another crusher reduces it further. It is used as road material and concrete aggregates, 2V2 inches and down; for roofing gravel, % to % inch; aggregates for making concrete blocks and lamp posts; station yard and track ballast, 14 inch and down; poultry grit, in sieye sizes for turkeys and old, young and baby chicks. PAGE 6 THE E. S. C. QUARTERLY WINTER, 1947 the heat of the sun and the cooler nights, or the cold of winter to continue the splitting process. By "soundings" on the surface, that is, tapping the granite with a hammer, it is possible by the sound produced to tell how far the split extends in all direc-tions from the original base of the hole. If it is dis-covered that the split is not extending in the direc-tions desired to get the sheet (if four to eight feet thick granite can be called a sheet) , then a new hole is drilled further along in that direction to a similar depth and black powder is exploded to extend the split already started. This undersurface split can and sometimes is extended over an area including several acres. So, it is possible to split off a sheet four to eight feet thick and acres in area. PEEL OFF HUGE GRANITE SHEETS Naturally, such large -sheets cannot be handled. When the area is sufficient for current needs, holes are drilled perpendicularly a few inches deep and a few inches apart. The wedge principle is used to separate the entire sheet of the blocks. Wedges are driven into these shallow holes and tightened grad-ually. Due to the markings made by the drilled holes, the granite splits perpendicularly almost as regularly and evenly as it does horizontally. The heat and cold expansion and contraction also help this process of cutting the blocks of granite to the size needed. Sizes of granite blocks are limited to capacity of railroad cars. It is possible for cars to carry a max-imum of 100 tons, although 50 tons is nearer the usual car. Twelve cubic feet of granite weigh about a ton. Maximum sizes of blocks are 40 feet by 5 feet by 5 feet. More usual sizes are 30x4x4 feet. The Arlington Memorial Bridge, connecting Wash-ington and Arlington Cemetery over the Potomac River, is one of the largest masses of Mount Airy granite. In its construction 685 carloads of granite were used. The weight of this granite is about nil^fP1*^ 'IP iBIIillllli Pennsylvania Monument at Gettysburg, Pa., honoring military leaders in War Between the States, including General Reynolds, one of the heroic figures.

A solid train of freight cars sufficient to haul the granite used in this bridge would be more than four miles in length. The Mississippi River bridge at Memphis, Tenn., now under construction and about 85 percent com-plete, will contain 320 carloads of granite. In this bridge will be seven granite piers, 100 feet high, 90 feet long and 20 feet wide. BY-PRODUCTS BECOME IMPORTANT At the Mount Airy granite quarry there is prac-tically no loss. The sizes are all used, from the largest cut stone to the fine grit fed to baby chicks to help them grind the food they take into their craws. The range is from cut and dimension stone down through paving blocks and street curbing, flagstones, rough ashlar, rubble, rip-rap, crushed stone, gravel and poultry grit. This poultry grit production is de-velopinging into one of the firm's important sources of income. Several carloads are shipped each week, graded into grit for turkeys, grown chickens, broil-ers, fryers and for baby chicks. It supplies a needed product for another growing North Carolina indus-try— poultry raising. And, large quantities go to all states east of Colorado. Full utilization of the granite quarried is due to ex-tensive study and planning to take advantage of all sizes of stone and over a long period. Cut stone and dimension stone form more than two-thirds of the total sales, yet utilize only slightly more than one-fourth of the total volume of material. By-products are just that when attention is directed toward pro-ducing the main items, but when periods of slack big business occur, the by-products become the more im-portant products of the quarry. In the early 1890s the Cape Fear and Yadkin Val-ley Railroad was completed from Mount Airy to Wilmington, thus giving Mount Airy granite an out-let to other railroads. A spur track surrounds "The Rock" and passes the cutting and crushing houses. This railroad, now the Atlantic and Yadkin Railway, WINTER, 1947 THE E. S. C. QUARTERLY PAGE 7 connects at nearby points with other far-reaching railroad lines. Power for operation is supplied by electricity and by a 175-horsepower engine and two 150 -horsepower coal burning boilers. Electric cranes, compressors, granite crushers, locomotives, granite lathes, steam cranes, diesel shovels, granite saws, sand blast and other equipment are in operation at the plant. In-dicative of the value of this equipment is a new crusher just installed which cost $35,000. The Mount Airy granite quarry operates with a normal force of about 400 workers. With veterans returning for training they are gradually getting back to that level. Many former G. I.'s are learning the granite business. And more could be used. At the peak of operations in 1925-1926 about 800 workers were employed. During the war period and the later restrictions in building, the industry was hard hit in its bigger operations, the by-products saving the day. However, production is gradually returning to normal, and the granite industry hopes to get going in a big way in the next few years. The labor at the quarry is native, efficient and sat-isfied. Many workers have been on the payroll al-most since they became old enough to work. In fact, at "The Rock" may be found grandfathers, fathers and sons working side by side. Notable is the cleanliness and neatness observed at the quarry. Unsuitable parts are cleaned up just about as soon as they accumulate in the production of the many by-products of the quarry. The keep-clean thought is stressed and new workers soon re- . alize that they are to keep the place clean and neat. It soon becomes regu-lar routine. That is why the place al-ways has the ap-pearance of just having been scrub-bed and swept. Mount Airy gran-ite officials are awaiting the all-clear signal, when the immediate needs of veterans and others for housing have been met. Then conditions are ex-pected to be so they can proceed with big contracts for build-ings and bridges, as well as for monu-ments, memorials, mausoleums and other smaller prod-ucts of the quarry.

TALC MINING IS AN IMPORTANT ACTIVITY IN CHEROKEE COUNTY Talc mining is developing into an important indus-try in Cherokee County. Two or three talc mines have been operated in various sections of the country, but a rich vein has been struck not far from the town limits of Murphy and is now being worked extensive-ly. Large quantities of talc are being mined a short dis-tance underground by the Hitchcock Corporation, headed by Francis Bourne, and is being processed in a plant at the mouth of the mine. Talcum powder, of course, is the first item thought of when talc is mentioned—and is an important item produced by the Cherokee County Plant. The lump talc is ground into a fine powder and that is talcum powder, practically the finished product, except for the addition of perfume. The Hitchcock Corporation also produces talc pen-cils which are used in marking all kinds of materials, especially iron and steel, which have to be subjected to intense heat. Talc marks, numbers to identify iron and steel parts, are just as plain after these ma-terials have been subjected to intense heat as they were before. Two types of pencils are made by this plant. Both are about six inches long. One is a round pencil, about the size of the usual lead pencil, but composed entirely of talc. The other is a flat pencil, approxi-mately the shape of a carpenter's pencil, also com-posed entirely of talc. The waste talc from trimming or turning these pencils is suitable for making talcum powder. Talc is described as a mineral composed of mag-nesium, silica and water, and is commonly classed as hydrous, magnesian silicate. It is soft and has a greasy or soapy feeling. Talc is related to soapstone, although talc is classified as a mineral and soapstone is of the rock family and is composed of talc, chlorite, and impurities. Like talc, soapstone is soft and has a greasy or oily feeling. PAGE 8 THE E. S. C. QUARTERLY WINTER, 1947 President James Buchanan Memorial, Meridian Hill Park, Washington. D. €., Balfour Pink granite from Rowan County. Balfour Pink Most Noted of Rowan County Granites By M. R. Dunnagan, Informational Service Representative, ESC Nearly 200 years ago a settler moved into Rowan County, North Carolina, and took up his abode. Within a few years he built a house. Many other settlers built houses. The difference is that this set-tler built a house which is still standing, while other houses have been built and burned or rotted away, and the settlers rebuilt or moved on. But this settler, Michael Braun, by name, built a house of stone, or more accurately, of granite, and had the foresight to place his name in the stone over the doorway. That stone, the name and the stone house are still there, now honored landmark, known as the "Old Stone House" and visited as a place of unusual interest by people of many states. Michael Braun's house, erected in 1766, was made of neighbohood surface stone, probably chipped and chiseled into shape and formed into a dwelling by slave labor Today, as 180 years have passed, it stands intact, except in spots where the woodwork has decayed and allowed the stone to shift. Near the "Old Stone House," the Balfour Pink, the Carolina Pink, the Shuping and the Dunn Moun-tain quarries are owned by The Harris Granite Quar-ries Co., and, since Michael Braun's day, have fur-nished great quantities of the highest test, most in-destructable granite to be found on earth for erec-tion of millions of dollars worth of public buildings, bridges, mausoleums, monuments, memorials, and in building highways and streets in many states, and in foreign countries. Note—Material used in this article was furnished largely by John E. Ram-sey, vice-president and general manager of the Harris Granite Quarries Co., Salisbury, N. C. "Old Stone House" four miles out of Salisbury. Erected in 1776 by Micnael Braun of Roivan County granite, near one of the present famous quarries. Still standing and almost intact, it is one of the shoto places of the State. BALFOUR PINK—"GRANITE ETERNAL" Balfour Pink—the best known of the Rowan County granites, by U. S. Government tests, is one of the hardest, toughest and most durable granites known. It takes a very high polish. It is truly a "Granite Eternal." The Federal Trade Commission, desiring "truth" in advertising, questioned the trade mark "Granite Eternal" under which it was sold. John Ernest Ramsay, vice-president and general manager of The Harris Granite Quarries Co., who has been in charge of quarrying and testing Balfour Pink Granite, replied as follows : "We use the word 'Eternal' in the same sense as it is found in the Holy Scripture when it speaks of "The Eternal Hills." The hills are in many instances based on granite, their surfaces change, but Balfour Pink Granite, cooled and formed before the existence of man has not shown but slight erosion since its formation, and it is more permanent than 'The Eternal Hills'." The trade mark "Granite Eternal" continues. Official tests show that Balfour Pink Granite is composed of: Silica (quartz) 76.06, Alumina 14.10, Potash 6.00, Soda 2.01, Iron Oxide 1.20, and traces of lime manganese and Titanium Oxide, Sulphuric and Phosphoric Anhydride. Other qualities: Loss on ignition .12, water absorption .772, crushing strength 34,860, percent of wear 2.0, hardness 18.7. Microscopic examination reveals the complete inter-locking and entwining of its crystals, showing its dense and compact and homogeneous structure. The above chemical and physical tests, setting forth low absorption and dense structure, prove Bal-four Pink Granite to be eminently suitable for polish-ed, hammered, honed, stippled and quarry face fin-ishes, and for use in permanent structures, monu-ments, mausoleums, public buildings, bridges and highway construction. Liner blocks for tubular mills, pebbles for pulverizing and grinding, Durax and paving blocks for heavy traffic and steep grades in streets are manufactured from the high test and durable granite and are receiving a ready sale. Balfour Pink, "highest test" of the Rowan County granites takes an unusually high polish, revealing WINTER, 1947 THE E. S. C. QUARTERLY RAGE 9 a slight purplish tint. When carved or lettered, it has a decided contrast of color, and is extensively used for memorials and public buildings. Carolina Pink Granite, when polished is slightly darker, having a creamy peach-glow tint. It is not quite as hard as Balfour Pink Granite, and is manu-factured at a slightly lower cost. The Harris Gran-ite Quarries Co. also owns Dunn Mountain, Shuping, Powlas Mountain, and Rowan quarries which are not in operation—owing to labor shortages. WENDELL WILLKIE MEMORIAL Recently a Memorial to Wendell L. Willkie, Can-didate for President of the United States, has been cut from Carolina Pink Granite and erected at Rush-ville, Indiana, and unveiled last fall.

The turn of the century brought many mechanical inventions and im-provements in the methods of quarry-ing and cutting granite. More than forty years ago, F. W. Ruckstuhl, French sculptor of the Con-federate Monument, Salisburg, called upon Mr. Ramsay, a Salisbury architect requesting informa-t i o n concerning Rowan granites. As Wendell L.

Loading a railroad car with the famous Rowan County granite at the quarry near Salisbury. the pedestal of their memorial of "Native Stone," Ruckstuhl was taken to the small opening of the Bal-four Pink Granite Quarry, by Mr. Ramsay, and upon examination of the granite, was so highly pleased that he said: "This is one of the most beautiful granites I have ever seen. If I were you, I would soon be in the granite business." Mr. Ramsay later became as-sociated with Mr. George R. Collins who came to Salisbury from Asheville in the operation of the Bal-four Quarry. Subsequently, after several years, Mr. Ramsay became vice-president and general manager of The Harris Granite Quarries Co., largely owned and organized by the late Charles J. Harris of Dills-boro, N. C. IMPORTANT LOCAL INDUSTRY The quarries are all open-face pits. The Balfour Pink quarry now covers more than five acres and in places is more than one hundred feet deep. All of the quarries are within a radius of six miles of Salisbury, N. C. The Cutting Plant is within the city limits of Salisbury, on the Southern Railway line to Atlanta. The offices of the company are in the Wallace Build-ing. Representatives of the companies have travelled extensively presenting the beauty and qualities of Rowan County Granites. Many contracts have been secured, and thousands of dollars have been brought into the county from the sale of one of nature's de-posits. During World War II, practically all granite products were declared to be non-essential, labor from the quarries left for other industries, and have not all returned, and the companies are greatly be-hind in making deliveries. During the War Period, liners, grinding and pulverizing stone could not be obtained from over seas. The Harris Granite Quar-ries Co. erected mills, produced pebbles of various sizes for grinding and pulverizing, and lines blocks for lining tubular mills, thereby assisting in the War effort. The Harris Granite Quarries Co. has a large plant located in South Salisbury, equipped with highpow-ered electric cranes, air compressors, granite saws, polishers, carbo saws, surfacers, sandblast room, (Continued on Page 27) PAGE 10 THE E. S. C. QUARTERLY WINTER, 1947 International Demand for Cherokee County Marble James Chadwick, Assistant Secretary Columbia Marble Company, Marble, N. C. Marble is one of Cherokee County's valuable raw materials. The main marble outcroppings are evi-dent at Hewitts in Swain County near the Nantahala River and extend almost due south into Cherokee County approximately twenty-five miles to Valley River. In the center of this zone, near Marble, the choice blue and grey marble is quarried. A smaller marble belt begins at the head of Peachtree Creek and runs parallel to the above marble nearly ten miles to Little Brasstown Creek. Perhaps the first marble quarried in Cherokee County for a commercial purpose was by the Notla Marble and Talc Company in 1900. Their quarry was located five miles southwest of Murphy and was named Kinsey Quarry. The marble quarried was good but the only sales made were for flux. In 1902, the Regal Marble Company was opened by Captain Brady at Regal, three and one-half miles northeast of Murphy with B. M. Harben as general manager. The company had a personnel of thirty men and this marked the real beginning of the marble industry as a manufacturing enterprise. The first operations of this company was quarrying the marble and sawing it into slabs for shipment. The next owner of the Regal company was the Casparis Marble Company. This company began the fabrication of the marble into monuments. CHEROKEE COUNTY COURTHOUSE Raymond Harris was the next manager. It was under his direction that the stone for the Murphy courthouse was made. The courthouse, a two story structure approximately three hundred by two hun-dred fifty feet, was built in 1926 and 1927 out of Regal Blue marble. It contains about twenty-five offices and the courtroom. Four massive blue marble William Jennings Bryan, "the Great Commoner," three times candidate for President. The base is of Ten-nessee marble, hut the carving was done at the plant of the Columbia Marble Co. at Marble, N. C. It con-tains about 500 cubic feet of Marble.

The Murphy General Hospital at Murphy is also constructed of a conglomerate of Cherokee County marble. columns support the roof beneath the dome. In the dome, the town clock, an eleven hundred pound bell, and a siren are located. The entrance to the courthouse leads in-to a rotunda fifty feet high. From the rotunda, hallways lead to the various offices. During the Regal operations, three quarries were open-ed. They ranged in depth from one hun-dred to one hundred thirty-five feet and all yielded blue mar-ble. Business became dull and J. A. Martin bought the company and moved to Mar-ble, ten miles north-east of Murphy. His operations were chiefly crush-ed stone and its products. The company was then acquired by Hinds and Adams of New York. They kept it only a short time and the Columbia Marble Company of which B. F. Coggins was president purchased it. In 1931, the company moved one mile east of Marble and located on the Southern Railway. A steel finishing plant one hundred fifty feet by two hundred sixty feet was built. Modern machinery was installed and two overhead cranes were erected to facilitate operations. When operations began, there was approximately forty-five thousand square feet in the quarry area. MANUFACTURING PROCESSES The company uses the following process to manu-facture a monument or slabs for buildings. Four gang saws divide the blocks into slabs and these are sent to two diamond saws for further division. Three rubbing beds are operated to put a smooth finish on the marble. At this point, the marble begins to take the shape of monuments or slabs of buildings. After the smoothing process, it is sent to the cutters benches where it is cut in various designs by pneu-matic air hammers and carborundum saws. Two polishing machines are used to put the silk like gloss on the marble and to bring out its beautiful texture. Expert designers then place the designs and letters WINTER, 1947 THE E. S. C. QUARTERLY PAGE 1 1 on the marble with tools and sandblast equipment. The memorial is then finished and sent to the ship-ping department to be crated and shipped. Columbia Marble Company contributed a large part to the defense program by selling the steel shed and two overhead cranes to Hinderliter Tool Com-pany of Tulsa, Oklahoma in the early part of the war. They dismantled the building and moved it to Tulsa where it was reconstructed as a part of a defense plant. After the steel building was removed, the company built another finishing plant at the same location. In 1945, T. A. McGahey of Columbus, Mississippi purchased the Columbia Marble Company. At the present time, he is President-Treasurer. The other company officials are : T. A. McGahey, Jr., Vice-Presi-dent- Secretary ; James Chadwick, Assistant-Secre-tary ; and Edward Plesko, General Manager. The quarries of the Columbia Marble Company produce two types of marble. They are Regal Blue and Sterling Grey. These marbles are crystalline in texture and their main constituent is limestone. They take a high polish and the absorption of water is low. The stone is durable and suitable for both monu-mental and building material. Although practically all the marble quarried is manufactured into a finish-ed product, there is some waste or scrap. This is sold locally to build buildings or sent to paint com-panies or iron mills for fluxing purposes. Alabama, Vermont, and Tennessee marble are also bought and sold by the Columbia Marble Company. The sales of the Columbia Marble Company have become almost universal. The marble is sold in all states, Canada, Hawaii, and in the islands south of Florida. Sales have consisted of monuments, bank fronts, mausoleums, soda founts, baptismal bowls, grave vaults, and interior and exterior marble for buildings. MARBLE IN NOTABLE BUILDINGS Some of the outstanding jobs completed at Co- Statesville Post Office, lobby view, showing the wainscoating of Sterling Grey marble and base course of Regal Blue marble from, the Columbia Marble Go. plant at Marble, N. G. lumbia Marble Company are parts of the following: Supreme Court Library in Washington, D.

Post Office and Courthouse in Statesville, North Carolina ; Saint Mary's Roman Catholic Church in Saint Petersburg, Florida ; and The Schwob Company in Columbus, Georgia. The outstanding monument processed was the memorial to William Jennings Bryan. This monu-ment had approximately five hundred cubic feet of Tennessee marble in it and required about thirty days to carve. A five-ton crane would not lift one piece of this monument because of its weight. The Columbia Marble Company is operating six days a week and furnishing gainful employment to about forty-five people. It's officials are looking to-ward the future with optimism in anticipation of do-ing a larger and better business in the marble in-dustry. In December, 1946, it was found by UCC officials that 62 claimants for unemployment benefits in the regular UCC program had received benefits in prior months to which they were not entitled, aggregating $2,362.00. In 16 cases involving evidence of fraud, the UCC has or will prosecute the recipients. In the other cases demand for repayment of the amount in-volved has been made. Those not refunding the amount will have it charged against their accounts and deducted from any benefits they may be due to receive when and if they file claims for benefits later.

"*: i ' : '. -. PAGE 12 THE E. S. C. QUARTERLY WINTER, 1947 Behind Scene In Locating Stone for Duke University By Brent S. Drane, Engineer, Construction Division United States Civilian Production Board Several months ago a chance inquiry by a friend of mine started me on the task of recapturing the record of the chain of events which located the stone from which the new Duke University was built. It was surprising how disjointed and scattered I found the links in the record, and, most of all, how inade-quate was the record of the matter in the files of the Geological Survey. Now that I have the record in hand, it seems to me that I ought to take pains to see that the full account gets into the Survey's public rec-ords ; because it reflects upon the Survey credit in keeping with its highest traditions. I am therefore addressing this letter to you for that purpose. I take the privilege of writing it as a friendly personal narrative rather than in crabbed, scientific report style ; but it is, I believe, entirely ac-curate for all that. For the background picture I am using John Wilbur Jenkins' account in his "James B. Duke, Master Builder." In this matter he gives a trained journal-ist's straighforward account of events then quite re-cent, involving people whom he knew and understood. Mr. Jenkins describes the 1924 establishment of the Duke Foundation, which transformed Trinity College into Duke University; Mr. Duke's close per-sonal concern with every detail of the evolution; his choice of the architect whose Princeton buildings he liked. He tells of the apparent impasse when prices of adjacent land needed for expansion of the old Trinity Campus climbed to levels which Mr. Duke de-clined to pay ; of the proposal to buy the large unde-veloped woodland area which the new Duke Univer-sity now occupies, and of Mr. Duke's pessimistic dis-belief that the purchase could be negotiated secretly enough to prevent another hold-up ; of how Professor Flowers, the University Treasurer, had to beg to be NOTE: This article is in the form of a letter from Brent S. Drane, Washington, D. C, who, at the time of the inci-dents described in it, was State Director of the old North Carolina Geological and Economic Survey, to Dr. Jasper L. Stuekey, then, and now, State Geologist, with the State De-partment of Conservation and Development, which succeed-ed the Geological and Economic Survey. Mr. Drane, formerly of Charlotte, was for some years an engineer with the Water Resources Division of the National Planning Board in Washington. Subsequently he served in the Water Division of War Utilities of the War Production Board. He is now with the Construction Division of the Civilian Production Board. He first wrote the letter to Louis Graves, Chapel Hill publisher. A copy happened to fall into the hands of our M. R. Dunnagan, who, because of its historic value, asked Mr. Drane's permission to use it. Realizing the importance of the information to posterity, Mr. Drane embraced it in a second letter to Dr. Stuekey, so it could become a part of the public records of the Mineral Resources Unit of the Department of Conservation and De-velopment. Since the original letter was addressed to Mr. Graves, he was given opportunity to make public the letter to Dr. Stuekey, which he published in his Chapel Hill Weekly of January 31, 1947. Mr. Dunnagan was also given permission to use it in this issue devoted largely to granite, marble and other stone products in North Carolina.—Henry E. Kendall. allowed to see what he could do, and of his success that astonished and delighted Mr. Duke. He tells how Mr. Duke had test panels built of the various building stones proposed by his advisers so that he could see for himself just what each looked like ; and how, when the general choice fell on a stone from a distant State which would have cost a fortune to transport, he called for backing up and starting all over again with more study of what lay nearer at hand. MR. DUKE CALLS FOR STONE So much for the stage setting. Mr. Duke had told his employees and Duke faculty collaborators to get out and find him a new quarry. There is no doubt in the world but that under those circumstances a new quarry was going to be found, and a good one; for there was a great deal of pressure behind the old gentleman's mild expression of his desires, as I had HURONIAN SLATE, USED IN DUKE UNIVERSITY BUILDINGS, DEFINED By Dr. Jasper L. Stuckey, State Geologist State Department of Conservation and Development The Huronian Slate Belt, from which the stone for the buildings on the west campus of Duke University was ob-tained, has been of interest for more than one hundred years. It was first described by Denison Olmstead in 18 25 in a print-ed report entitled "Report on the Geology of North Carolina Conducted Under the Board of Agriculture," published by J. Gale and Son, Winston-Salem, North Carolina. In this report, Olmstead described the "Great Slate Formation" in Person, Orange, Chatham, Montgomery and other counties. The slate belt was further described by Ebenezer Emmons in his "Geology of the Midland Counties of North Carolina," published in 18 56. W. C. Kerr, in his "Geology of North Carolina," published in 1875, added the name "Huronian" in his description of the slates. Olmstead, Emmons, and Kerr all considered the rocks of the slate belt to be normal sediments which had been changed to slate by metamorphism. G. H. Williams, Professor of Geology in the Johns Hop-kins University, studied a small area of the slate belt in Chatham County and published a paper on his work in the Journal of Geology, Vol. 2, 1894. He described the rocks as volcanic flows and breccias with finer tuff deposits, all metamorphosed into slates by dynamic agencies. The Carolina Slate Belt, as it is known today, embraces a belt of country which varies in width from eight to fifty miles and extends in a general northeast-southwesterly di-rection across the State. Its western boundary is marked by a line a few miles east of Greensboro, Lexington, and Charlotte. Its eastern boundary is marked by a line a few miles west of Durham, Sanford, and Wadesboro. The rocks of the area, because of the complex character and well defined cleavage, have been called "slates"; but the name is misleading and confusing. They consist of vol-canic- sedimentary formations made up of slates and tuffs with which are long interbedded bands and lenses of vol-canic breccia, flows and ash. There are two distinct types of tuffs, breccias and flows: one is acid and the other a more basic phase. The acid phase consists of fine and coarse tuft's, and breccias chiefly of a rhyolitic and dacitic character, with flows of rhyolite and dacite. In the basic phase the breccia and flow types are more common than the fine and coarse tuffs, but the latter are usually present in at least small amounts. Both phases are more or less stained and colored by weathering. The acid phase contains gray, red-dish, and brown colors while much of the basic phase is greenish in color due to the formation of epidote in it. WINTER, 1947 THE E. S. C. QUARTERLY PAGE 13 observed in an interesting experience I had once had with him. The only question now was how to find it in an atmosphere so over-charged with suspicious fearfulness and secrecy, a hang-over from the land-price impasse which had just been escaped. Your and my connection with the business began, as I connect up the dates, early in January, 1925, when I was the new Director of the State Geological and Economic Survey and you were the new State Duke University Aik View—Duke University's massive build-ings. West Campus, erected on a plateau nearly a mile long and one-third of a mile wide and located about a mile west of the City of Durham, were constructed of stone taken from a quarry about 15 miles away, located a few miles west of Hills-boro, near the Eno River, close to the Southern Railway tracks and a short distance from the State Highway between Hillsboro and Efland. The stone is classified as Huronian slate, similar to a stone found near Lake Huron. In the quarry, owned by Duke Univer-sity, were found all of the seven primary colors and seventeen different shades of these colors, making it particularly suitable and beautiful for development of a great university plant. The quarry is said to contain enough desirable stone to erect an-other group of buildings as large as those which make up the main part of Duke University. To the left is the Duke Chapel. To the rear right is the front of Duke Hospital. The Duke Stadium, not shown, is to the lower left. Geologist. I was on an evening train for Greensboro, just past Durham, when I was joined by a Charlotte friend, member of the construction company which was doing Mr. Duke's experimental work in Durham. After a little he got me to go with him to his seat to look at some stone specimens he had in his bag. With extravagant caution against being seen or over-heard, he showed me several pieces of lustrous black hornblende gneiss, and asked me if I knew where it could be found in quantity. I thought that I did and proposed to verify my ideas and write to him. He knew that I knew enough of Mr. Duke's plans and of his own connection with the sample panels of mason-ry on Trinity Campus to make his present interest no mystery to me. Upon undertaking to keep our talk confidential, he told me in some detail of the Princeton buildings that Mr. Duke had picked as his prototype. In conclusion I advised him to consult with you, the State Geologist. DR. STUCKEY IS CONSULTED Promptly after this the Business Manager of the new Duke University came into the picture, a Pro-fessor of English whose keenness in practical matters PAGE 14 THE E. S. C. QUARTERLY WINTER, 1947 had brought him to the front in Trinity College's business management. He called at the Geological Survey offices in Raleigh and was promptly turned over to you. Happily, you were extraordinarily well prepared for just such a consultation. Back in 1920 at Dr. Pratt's suggestion you had made a collection of more than a hundred specimens representing the range of building stones found in North Carolina, and the collection was still intact at the Survey's old quarters at Chapel Hill. After a general discussion with him, you made an appointment to meet him later in Chapel Hill to show him the specimens and give him more information based upon them. Very shortly after that you had a visit in Raleigh from my contractor friend. He told you of our earlier discussion on the train, showed you what doubtless were the same specimens of hornblende gneiss he had shown me, and gave you to understand that they represented a type of stone sought in con-nection with the Duke University building program. Your knowledge of the occurrence of this stone in western North Carolina was of course much more definite than mine had been ; and you gave him what information you could about its occurences nearest to Durham. Several days later you got a letter from him and a small package containing several other specimens of stone ; the letter stated that these, rather than those he had shown you on his visit were of the type par-ticularly wanted for the Duke buildings. You brought the new specimens to me for examination, and we discussed them in some detail. We both recognized the mailed-in samples as similar to material used for flagstone in Chapel Hill ; and we recalled that it was quarried somewhere near Hillsboro. As a result of our discussion we agreed that you ought to learn all you could about the Hillsboro sources before meeting the Duke Business Manager, Professor Brown, at Chapel Hill. LOUIS GRAVES' FLAGSTONES Here is where some of my close personal friends become active helpers. I recalled particularly the flagstones Louis Graves had at his home in Chapel Duke Hospital—Showing entrances to lobby and clinic. Hill ; I had noticed them and asked him about them. I consequently wrote from the Survey Office in Ral-eigh on January 15, 1925, to my friend Cheshire Webb, an active and public-spirited business man in Hillsboro. ''I am very much interested to know where the old stone flagging used around Hillsboro came from. I recall that Louie Graves sent to Hillsboro for flags to put in his yard. Won't you try to get all the dope you can to me from the old residenters?" Mr. Webb replied at once that he knew the quarry from which the flagstone had come; and that he would be glad to show it to me or to anyone I might send to him. That one was, of course, yourself. On the morning of the day set for your afternoon ap-pointment with the Duke Business Manager, Mr. Brown, in Chapel Hill, you went first to Hillsboro and got in touch with Mr. Webb. He took you out to the old quarry, and there you collected a number of speci-mens. That afternoon after reviewing with Mr. Brown your collection in the old Survey Offices in Chapel Hill, you showed him your Hillsboro specimens. He professed to be somewhat critical of them, but he could not entirely conceal an eager interest; and he asked permission to take several of the specimens with him. Bright and early the next morning he wag in Hillsboro, calling on Mr. Webb. That ends the story of the finding; but Mr. Webb's concern in the matter, which was of major import-ance, continued. At Mr. Brown's request he obtained a purchase-option on the quarry-farm. I have a letter which Mr. Brown wrote him dated "24 January," cautioning him ; "Please be sure to have the man's wife sign it ; otherwise it is not of much value ... As soon as the option is signed I shall be grateful if you will notify me that we may make an examination of the quarry." CHESHIRE WEBB HANDLES DEAL Two options are recorded in the Hillsboro Court House, both signed January 31, 1925, and filed for registration February 3. One was a 60-day option on the right to acquire for $595 in cash, the right to mine and remove the rock and stone from the land, except an 8-acre tract immediately surrounding the dwelling house. The other was an option on the right to buy the 72-acre farm outright for $4,000. I have a letter which the University Treasurer, Professor Flowers, wrote to Mr. Webb on March 26, 1925. The options were about to expire, and Mr. Webb had evi-dently told him that if the University did not want the property he intended to buy it. The letter states that Professor Flowers wishes "to confirm the state-ment made on the telephone last evening" ; that if Mr. Webb will relinquish the options to him he will undertake to endorse them back to him if they are not exercised before the date of their expiration ; and if the options are exercised and the stone then found not suitable for the University's purpose, he will give Mr. Webb the opportunity to acquire the rights under the options at the same price they cost. "I appreciate WINTER, 1947 THE E. S. C. QUARTERLY PAGE 15 very highly the help you have rendered us," he said. I have also a letter from Mr. Brown to Mr. Webb rather elaborately stating his appreciation for his "fine and unselfish spirit in being so willing to do such a service for the institution." On March 31, 1925, the land was bought under the purchase option by a Durham real estate agent acting for Duke Uni-versity, and he gave deed to Duke University on April 24 following. Your records show that you made five subsequent trips to the property with Mr. Brown. In the course of the investigation the latter got the State Highway Commission to make some tests of the Hillsboro stone, with the arrangement that you should write the interpretation of the tests. Later on, Professor Flowers arranged for tests and a report by the United States Bureau of Standards at Washington, and he sent you a copy of that report. It pleased you to find that you had been more conservative in your inter-pretation of the Highway Commission tests than was the interpretation of its own tests by the Bureau of Standards. Its soundness having been proven by tests, the great value of that particular body of stone lay in its nearness to the Hillsboro-Durham railroad. It cost relatively little to build a short spur-track into the quarry, so that quarried stone coud be mechanically loaded at very low cost directly into a railroad car and cheaply transported to the very site of the build-ing for which it was destined. The perfect combina-tion of high quality, easy accessibility, and low-cost transportation—to say nothing of its low purchase-cost, all made that particular quarry the kind of a find that delights a construction man's heart ; and at heart Mr. Duke was a construction man. This was exactly what he had told his people to get out and find. GEOLOGICAL SURVEY HELP RECORDED But the way in which it was found has, I think not heretofore been recorded so as to give proper credit to the Geological Survey. The well-established tradi-tion that a business-like Professor did the finding has exalted a middle-man. to the complete obscura-tion of how the desired stone actually came to be found in this particular outcrop. It was inconspicu-ous, little known, not actively worked as a quarry, and the chance was infinitesimal that it ever could have been thought of as a site for a larger quarrying oper-ation. But the Duke University Business Manager had more luck than anyone could have had any right to expect when he followed the logical course and consulted the State Geologist. That State Official happened to have been particularly prepared for this very job by his eminent predecessor, Dr. Joseph Hyde Pratt. But beyond and entirely apart from that, "The long arm of coincidence" must be given a large share of the credit ; in the circumstance that I hap-pened at the time to be Director of the State Geolog-ical and Economic Survey, that Louis Graves and his flagstones in Chapel Hill were my good friends, and that Cheshire Webb in Hillsboro was a good and loyal ally of mine, ready and zealous to help bring to a handsome conclusion a matter of the old Geological Survey's business in which I had asked his friendly help. UNEMPLOYMENT DECREASES: AVERAGE WEEKLY WAGES SHOW AN INCREASE Industry in North Carolina is making a strong effort, and with a marked degree of success, to over-come the natural and man-made handicaps that grew out of the World War II crisis, as indicated by the increase of workers in covered employment. In a compilation prepared by S. F. Campbell, of the Bureau of Research and Statistics, it is revealed that covered employment in North Carolina in the second quarter of 1946 was only 8.7 percent below the highest level reached during the all-time high period in the early war year of 1942, when 591,391 workers were in covered employment. During 1942 war camp construction was at its height and Selective Service withdrawals had not reached their peak. In one quarter of that year covered employment exceeded 600,000. Selective Service withdrawals, demand for workers in war industries in other states and halting construction work generally reduced the covered labor force in the State to 509,352 workers in July, 1945, the lowest point reached. From that date employment began to increase, despite the lay-off of about 70,000 war workers in August, 1945 ; by September 527,527 were employed and by December 539,180 covered workers were employed. Also, during this period, wages were showing a steady increase, an increase of 30.9 percent from $23.75 average weekly wage in 1942 to $31.10 in 1945. From an average weekly wage of $17.44 in 1940, the increase was 78.3 percent by 1945. By comparing the wage increases in North Caro-lina with those of the nation, Mr. Campbell points out that the State still has nothing to boast about. Whereas, he finds, the average weekly wage of wage earners or production workers is still below the national level, the average salaries of corporate officials and administrative personnel are lower still when compared with the national level. Indications are that a small drop may be seen in average weekly wages of covered workers in 1946, as compared with 1945, due to the discontinuance of war-time shipbuilding, ordnance and electrical ap-paratus. Skilled workers in these industries are not being replaced by activities which require labor of comparable skill and earning capacity. Unemployed workers in North Carolina had been paid through March, 1947, a total of $32,059,842.20 from January 1938, when benefits were first paid under the Employment Security program. Liable employers had paid $147,227,679.30 in contributions into the fund, which, deposit in the U. S. Treasury, had earned $9,810,204.10 in interest. This gives total receipts of $157,037,883.40, and a balance on March 31 of $124,979,041.20. PAGE 16 THE E. S. C. QUARTERLY WINTER, 1947 State's Limitless Store of Non-Metallic Minerals By T. G. Murdock, Assistant State Geologist North Carolina Department of Conservation and Development GENERAL FEATURES OF THE GEOLOGY It would be expected that the first state to have sponsored geologic research and to have had a formal-ly organized geological survey since 1852 would be an important producer of a wide variety of rock products. Although a generous nature has endowed North Carolina with over 300 different minerals and many kinds of rocks, the deposits of metals and min-eral fuels are small in comparison with other states. This situation has led to the development of the in-dustrial rocks and minerals—the less spectacular non-metallics. The Mineral Resources Division of the North Caro-lina Department of Conservation and Development is actively engaged in a broad program of geologic re-search under the direction of Dr. Jasper L. Stuckey, State Geologist. Since 1936 the total value of the State's mineral production has more than doubled, and in 1944 established an all-time record. North Carolina has a total length from east to west of 503 miles and lies across three geological prov-inces : The Coastal Plain, Piedmont Plateau, and the Appalachian Mountains. The rocks and minerals and their geologic relations in each province are dis-tinctive. Stratigraphically the rock formations range from ancient pre-Cambrian crystallines of the Mountain Province to coastal and estuarine sands and gravels of Quaternary age, constituting the most easterly formations. Thus the State's mineral re-sources have been formed by various processes and at many different times, in rocks ranging in age from half a billion years to a few thousand. The structure of the rock units in some parts of the State is simple and in others very complex. The Coastal Plain extends from the Atlantic Ocean on the east to the Piedmont Plateau on the west. Its area is about two-fifths of that of the State, exceed-ing 21,000 square miles and embracing wholly, or in part, 42 of the 100 counties. It is underlain by rela-tively young, loosely consolidated sediments that dip gently towards the ocean. The most important known mineral resources of the Coastal Plain are ce-ment materials, clay, greensand, phosphate rock, sand and gravel, shell limestone, shell marl, and peat. The Tuscaloosa formation is the earliest of the Cretaceous sediments in North Carolina and rests on the eroded edges of the basement rocks.

The Black Creek sands and clays and the Pee Dee sands are representative formations of the upper Cretaceous. An ideal section of the overlying Tertiary sediments shows that the Eocene is repre-sented by the Castle Hayne marls and shell rock ; the Miocene by the Trent, St. Mary's, Duplin, and York-town formations; and, the Pliocene by the Wacca-maw and so-called "Lafayette." "CAROLINA SLATE BELT" The central hill country, known as the Piedmont Plateau, attains a greater width in North Carolina than in the states to the north, and is also far more rugged. The western margin of this Plateau has an altitude of 1200-1500 feet above sea level. At places precipitious spurs of the Blue Ridge Mountains pro-ject eastward and southeastward across the Pied-mont section in irregular, straggling ranges. The area of this region is about 22,000 square miles ; its altitude descends gradually from 1500 to about 300 feet, with an average close to 1000 feet. The Piedmont Plateau is largely underlain by very old, highly deformed crystalline rocks with smaller amounts of well consolidated, gently folding sedi-ments. Mesozoic sediments, mainly shales and sand-stones, are represented by two areas of Triassic strata: The Dan River area of Stokes and Rocking-ham counties, and the larger Deep River area, com-prising the belt of central and south central counties from Granville to Montgomery. Algonkian rocks cover a large portion of the middle and lower Pied-mont Plateau—the area known as the "Carolina Slate Belt"—and consist of a great series of schistose volcanics and slates. This series is composed of ash and tuff of rhyolitic and andesitic compositition, flows of rhyolite and andesite, and beds of shale, all of which have been metamorphosed into schistose and slate-like rocks. "CAROLINA IGNEOUS BELT" The "Carolina Igneous Belt," composed principally of Carboniferous granite, occupies a nearly central position in the Piedmont Plateau and extends in a northeast-southwest direction from South Carolina on the south nearly to Virginia on the north. The width is 15-50 miles and it is traversed for most of its length by the main line of the Southern Railway. In addition to granite, this area is composed of diorite and there are numerous dikes of diabase and other basic igneous rocks which penetrate the older rock. The rocks of the western Piedmont are mainly of the pre-Cambrian Carolina gneiss formation, whose original nature is in doubt but it probably consisted of igneous and sedimentary rocks. The Carolina gneiss consists of a great series of interbedded gneisses and schists, chiefly composed of quartz, WINTER, 1947 THE E. S. C. QUARTERLY PAGE 1 7 varying amounts of acid feldspar and either musco-vite or biotite or both. At times either garnet or kyanite may be dominant minerals in the gneiss or schist. The rocks are light or dark gray, and have a fine grain, marked schistosity and, except for the larger crystals of kyanite and garnet, an even tex-ture. The Cambrian metamorphosed sediments form scattered belts and irregular areas in the upper Pied-mont Plateau and Mountain sections of the State. In their present condition these formations are largely schist, slate, and quartzite. The most important known industrial mineral deposits of the Piedmont Plateau are barite, clay and shale, granite and gneiss, kyanite, kaolin, limestone, marble, mica, monazite, pyrophyllite, quartz, sandstone, sillimanite, slate, soapstone, spodumene, and trap rock. The Mountain region of North Carolina includes the Blue Ridge, the Great Smoky Mountains, and the country between, which is occupied by numerous ir-regular ranges, often separated by narrow valleys and deep gorges. The average altitude of this re-gion is about 2700 feet above sea level but the sum-mits of many ridges exceed 5000 feet, and a consid-erable number of peaks tower above 6000 feet. Over the larger part of this region are to be found the older crystalline rocks, largely gneisses and granites, which are continuous with those of the western part of the Piedmont Plateau, and, like these, are con-sidered of pre-Cambrian age. These rocks are often greatly folded and faulted and extreme metamor-phism has frequently obscured or completely obliter-ated all traces of their original character. On the western and eastern borders of this mountain region, approximately along the line of the Blue Ridge and Great Smokies, are two narrow belts of younger rocks consisting of limestones, sandstones, shales, and conglomerates, and their metamorphic equiva-lents, crystalline limestones, slates, and quartzites. ANCIENT ROCK FORMATIONS The Mountain and Piedmont regions of North Car-olina are but a portion of the great belt of crystalline rocks that is coextensive with the Appalachian Moun-tain system. On account of their complex structure, and highly crystalline character, these rocks are generally considered to be of Archaen age. The prin-cipal constituent of this system is banded gneiss, which includes many masses of granitic and other distinctly igneous rocks, and which often, through higher development of lamination, passes into mica schists and amphibole-schists. The gneisses have been usually considered, in part, sedimentary rocks that have lost most of their orig-inal characteristics in the great earth movements and other metamorphosing agencies to which they have been subjected. Some of them are undoubtedly gran-ites, diorites, and other igneous rocks that have been sheared or squeezed by the same agencies, and tran-sitions from the massive to the laminated forms are common. £ (a s_ •"> „o o _i 5- <D QC g. 2 _s 1- <n Co Of (A 2 ro '<5 Q LL £; (0 UJ <j" o OS UJ Z o 1_ Q zo UJ UJ a.2 UJ r- Z < _l CD UJ c o - 4« UJ UJ 2 < £4 O -i _j O £ <n $<®$ Map of North Carolina Showing Diversity of Stone Deposits Map courtesy "Rock Products," MacLean-Hunter Pub. Corp., Chicago. PAGE 18 THE E. S. C. QUARTERLY WINTER, 1947 The different formations of the Mountain region have furnished suitable materials for construction and have in some cases been the host rock for eco-nomic mineralization, both metallic and non-metallic. However the pegmatites and peridotites have been the source of the major mineral development. Pegmatites are quite widespread throughout the Mountain region and even in some parts of the Pied-mont Pleateau. These rocks are closely allied to granite in composition and are commonly regarded as emanations from granitic magmas that have solidi-fied in dikelike bodies in the enclosed rocks. As in granite the essential constituents are feldspar and quartz, with more or less mica and other accessory minerals. The feldspar occurs in masses and rough crystals, some of them with a diameter of several feet. These rocks vary considerably in form, some being typically lenticular in shape and others more or less persistent in length. The lens-shaped bodies are generally conformable with the schistosity of the enclosing rock. They may lie in the same line of bed-ding or schistosity and be connected by smaller streaks or stringers of pegmatite, or by mere seams in the rock. Many of them, on the other hand, lie in planes of schistosity more or less separated from one another and form parallel or overlapping bodies. MICA AND FELDSPAR SOURCES Although pegmatites may be one mile or more long and 100 to 300 feet wide, they may be streaks a few feet, or even inches in length and width. Notwith-standing their deep-seated origin, they may pinch out in depth as well as laterally. The pegmatites have been extensively exploited and have been the source of the commercial mica and feldspar production of the State. Some of the quartz from pegmatites has been marketed and small amounts of beryl and co-lumbite recovered as by-products. At least 44 differ-ent minerals have been reported from the pegmatites of the Spruce Pine District. In addition to the typical occurrence of pegmatites a coarse-grained pegmatitic granite crops out over rather extensive areas in Mitchell, Avery, and Yan-cey counties. This material has been denominated "alaskite" and consists essentially of oligoclase, quartz, microcline, and muscovite, in order of abund-ance. Unlike pegmatites, in which irregular mineral distribution is the rule, the alaskite has a relatively uniform mineral composition and grain size. The alaskite was originally intruded as a magma into mica schist and biotite-hornblende gneiss ; these intrusions were later affected by much folding and faulting, and they now crop out in large irregular bodies. Upon weathering and decomposition the alaskite yields a kaolinized product, about 10 to 15 percent of which is recoverable as the residual china clay of the cera-mic trade. STATE LEADER IN KAOLIN For about 50 years North Carolina has been a lead-ing producer of this commodity, which when refined has an alumina content of 37-38 percent and consti-tutes a potential low-grade source of aluminum. In some places workable kaolin has been found to depths of 100 feet ; in others the proportion of hard feldspar is too great for profitable operation, even near the surface. A later development has been the process-ing of the unkaolinized alaskite and the recovery of the feldspar by flotation. Most of the peridotites and related magnesian rocks in western North Carolina are confined to the belt of gneisses and schists that lies chiefly west of the Blue Ridge, and are arranged generally in a some-what well-defined belt or belts within these gneisses. These peridotites are intruded into the central part of a great geanticline and many of these intrusives are thought to have been a part of a volcanic system once active in pre-Cambrian times. Many of the perido-tites are of the dunite and saxonite type and contain essentially pure olivine with smaller amounts of as-sociated primary minerals. Some formations and parts of others have undergone serpentinization. However there are at least 25 deposits which are re-markably sound and in North Carolina and adjacent parts of Georgia there are at least 230,000,000 tons of high-grade forsterite olivine, averaging 48.09 per-cent magnesia. The earliest development of the peridotites was for corundum and nickel silicates ; later associated talc, chromite, and anthophyllite as-bestos were produced ; and still more recently a ver-miculite industry has been developed to exploit this very unique group of minerals. For the past decade there has been a small but increasing production of olivine, for the refractory trade and for making mag-nesium salts. Olivine is also regarded by many as a future ore of magnesium metal. II.—COMMERCIAL ROCK DEPOSITS Granite and allied rocks have, for many years, been a chief mineral asset of North Carolina. The State ranks first in quality and second in quantity only to Georgia in the southeastern states. Quarries have been successfully developed from a location in the Coastal Plain near Wilson throughout the Piedmont Plateau and into the Appalachian Mountain region as far west as Hendersonville. "Balfour Pink" from Rowan County and "Mount Airy granite" from Surry County are names that have already become well established in the trade and are accepted as a guar-antee of high-grade monumental and building stone. The workable granites of the Coastal Plain region are exposed in Anson and Richmond Counties along the South Carolina line, and in Wilson, Edgecombe, and Nash Counties to the east of Raleigh. The gran-ites are essentially biotite granites and they show a considerable range in variation of color and texture, from light gray to pink with a very pleasing mixed yellowish and pink appearance in places. Within the northeastern Carolina Granite Belt, comprising Wake, Franklin, Warren, Vance, and Granville Counties, extensive workable areas of dif-ferent grades of granite are found, suited for all grades of work in which granite is used, except for the better grades of monumental stock. Although WINTER, 1947 THE E. S. C. QUARTERLY PAGE 19 production has been reported from numerous locali-ties in this belt the principal quarries are at Roles-ville and Wendell in Wake County and at Greystone in Vance County. GRANITE IN TEN COUNTIES The Carolina Igneous Belt comprises the main granite belt of the State. Extensive areas of granite are exposed more or less in each of the 10 counties included within the belt and, in each county some stone has been quarried from time to time, usually to satisfy local demands. The principal development is to the east and south of Salisbury where the earliest quarrying was many years before the Civil War. The Balfour stone is produced in the Salisbury area. Im-portant quarries for the production of crushed stone have been operated in the Greensboro, Burlington, Charlotte, Winston-Salem, Reidsville, and Salisbury areas. Massive granites are less abundantly distributed over the western Piedmont gneiss and granite belt than over some other parts of the State. The princi-pal development within the belt has been in Surry, Wilkes, Alleghany, and Alexander Counties. The granites of the belt are all-biotite bearing, usually of light color and of medium texture. The most import-ant commercial granite deposit in this belt, or even in the South, occurs in the northeastern section of Surry County, near Mt. Airy. The famous "Mount Airy granite" is noted for its beautiful white color. It is composed essentially of quartz and feldspar with a very small amount of mica, zircon, epidote, and very little iron oxide. The minerals are so arranged that a very uniform color is to be had throughout the en-tire deposit. The Appalachian Mountain granite area includes several of the mountain counties which lie between the Piedmont area and the Tennessee line. However, only three, Buncombe, Henderson, and McDowell, have shown a production during recent years. STATE CAPITOL OF GNEISS Gneiss made an important entry into construction in North Carolina more than one hundred years ago when the State Capitol was built of this type of rock which was quarried just east of Raleigh. In recent years there has been renewed interest in this rock throughout the State. Limestone, marble, and marl, although not present in unlimited amounts, are important mineral re-sources. More than one hundred years ago farmers in the eastern section were using marl as a fertilizer. During the recent military construction in that re-gion shell limestone was produced on a large scale from the Maysville-Belgrade area and from Warsaw. The marls and shell limestones of the New Bern area constitute a source of raw material for cement manu-facture and it is possible that such a utilization will eventually result. The crystalline limestones and marbles of the western part of the State have found a ready utilization. During recent years quarries have been operated in the vicinity of Kings Mountain, Yadkinville, Newton, Fletcher, Marion, Ashford, Nantahala, and Hot Springs. A dolomitic phase is recognizable in several of the limestones exploited, and a pure dolomite deposit is found in Mitchell County. Marble has been quarried in Cherokee County for more than 35 years. There are import-ant reserves of marble in this County—especially a dark blue or black variety known as Regal Blue which is very desirable as a monumental and ornamental stone. The exploitation of the sandstones in the State is limited wholly to the Triassic beds. These rocks are geologically and lithologically equivalent to the cele-brated brownstones in states further north. Al-though these stones have in the past been used lo-cally in Anson, Moore, Chatham, Orange, Wake, and Durham Counties successful quarry development has been retarded by the abundant jointing of the beds and a lack of uniformity in color. During re-cent years a small amount of sandstone and quartzite has been used for crushed stone. MONUMENTAL-ORNAMENTAL STONE The granites of North Carolina, in addition to a wide utilization as a monumental and ornamental stone, have been used in the past as paving stones and blocks. The wider use of concrete and asphalt has led to a decreased use for these purposes and a greater use as crushed stone. Granite millstones, from the Salisbury area, were formerly an important product, but these too are now produced on a very small scale. During the war period when imported grinding pebbles and mill liners were not available, the Salisbury granites were successfully used, the pebbles being formed by tumbling cubes of granite. A poultry grit by-product is made from the Mount Airy granite and has found wide acceptance. The stone industry is an important industry in North Carolina. The average annual production of all crushed stone in the State, for the period of 1935-44, inclusive, was 3,648,315 short tons valued at $4,- 577,137. The total value of the crushed stone pro-duction during 1944 was $5,349,378, a figure which was exceeded only slightly by that of the leading state—Pennsylvania. Clay for the production of brick, building tile, and sewer pipe comes from two sources in North Caro-lina. For many years the entire production came from the sedimentary clays of the Coastal Plain and from flood-plain clays along streams. Today import-ant amounts of clay products are being made from clays found near or on the flood-plains of the Roanoke, the Tar, the Neuse, and the Cape Fear rivers of the Coastal Plain and from flood-plain clays of the Yad-kin, Catawba, and French Broad Rivers and their tributaries in the Piedmont Plateau and Mountain sections of the State. During the past 25 years the clay shales of the State have become of importance for the production of structural clay products. Im-portant plants using Triassic shales are located near Sanford and Durham in the Deep River area and near Pine Hall in the Dan River area. A large plant near PAGE 20 THE E. S. C. QUARTERLY WINTER, 1947 Greensboro uses shales from both the Deep River and Dan River areas. Plants near Monroe, Norwood, Mt. Gilead, Denton, and New London use the pre-Cam-brian shales. The Cambrian shales are processed in a plant near Brevard. Structural clay products con-stitute the State's third mineral resource in value. MICA MINING STARTED EARLY Mica in North Carolina antedates historical rec-ords. Stone implements unearthed in old deposits show that, older even than Indian tradition, a race of men valued and mined for mica. Since 1903 North Carolina has supplied more than one-half of the total mica production of the United States. During World War II over 1500 mines and prospects produced stra-tegic grades of mica and in 1943 the production of sheet mica amounted to 1,901,120 pounds valued at $1,772,324. The mica belt covers twenty counties in western North Carolina and extends northeast and southwest across the State, reaching an extreme width of 100 miles. The most important mica pro-ducing counties are Ashe, Avery, Buncombe, Burke, Catawba, Cleveland, Gaston, Haywood, Jackson, Lin-coln, Macon, Stokes, Transylvania, Watauga, Wilkes, Yadkin, and Yancey. The State is also the leading producer of scrap mica which is ground by wet or dry process. Plants are in operation near Spruce Pines, Franklin, and Asheville. In addition to a production of ground mica from the scrap obtained by processing sheet mica and mined for scrap some mica schist is ground and the mica is recovered from kaolin-refin-ing operations. The first feldspar was shipped from North Carolina in 1911. By 1915 the State had become an important producer and has furnished approximately half of all the feldspar mined in the United States since then. The production has been from pegmatite dikes widely distributed throughout the upper Piedmont Plateau and Mountain sections of the State. Production at present comes chiefly from Mitchell, Yancey, Avery, and Swain Counties. Grinding plants are located in the Spruce Pine district, and near Burnsville and Dillsboro. KAOLIN, QUARTZ, TALC PLENTIFUL North Carolina has for many years been the lead-ing State in the production of true, non-plastic, resi-dual kaolin. Approximately 100 deposits, mines and prospects have been described at one time or other throughout the Piedmont Plateau and Mountain sec-tions. Some of the deposits have been formed through the kaolinization of the feldspar of pegma-tite dikes, however the bodies of kaolinized "alaskite" granite are the source of the present production which is from Mitchell, Avery, and Yancey Counties, an area where five refining plants are in operation. Halloysite, another clay mineral, is being produced from near Alexander, Buncombe County. Quartz occurs in veins of varying size at numer-ous localities in the Piedmont Plateau and Mountain section and also in pegmatite dikes in these regions. Small amounts of quartz were at one time mined in the Piedmont region and ground at Charlotte. Some quartz is also recovered as a by-product in feldspar mining and from sand and gravel washing operations. Talc is found associated with the Murphy marbles as lenses and irregular bodies in Cherokee and Swain Counties. A recent intensive exploration campaign has led to the opening up of two new mines and a re-vival of operations at others. A high-grade material is produced which can be utilized for the various re-quirements of the market. Talc also occurs at many places in western North Carolina in association with the peridotites ; Madison County has been the prin-cipal producer of this kind of talc. North Carolina is the chief producer of pyrophyl-lite in the United States. This talc-like mineral which contains aluminum instead of magnesium has been known to occur in Moore County since 1850 ; as a result of detailed geologigal investigation of the deposits, an important industry has been developed with mines in Moore, Randolph, and Alamance Counties. The pyrophyllite occurs chiefly in acid tuffs of the "Carolina Slate Belt." The 1943 produc-tion was valued at approximately $500,000. OLIVINE AND MONAZITE ABOUND Olivine production has been chiefly from Jackson and Yancey Counties. Although vermiculite deposits are known from Clay County northeastward to Avery County, the main development has been around Elli-jay, Macon County, and Swannonoa, Buncombe County. There is an important production of antho-phyllite asbestos in Yancey County and Avery County has likewise been active in this field. Monazite was formerly produced from placer de-posits, particularly in Burke, Cleveland, and Ruther-ford Counties. Barite mining operations have been carried out near Kings Mountain and in Madison County. More recently spodumene-bearing pegma-tites have been mined and milled near Kings Moun-tain. For some years kyanite was recovered from a large lens of kyanitic gneiss on Little Celo Mountain, near Burnsville, Yancey County, but the operation has now been suspended. A recent discovery of con-siderable importance is the occurrence of a belt of sillimanite schist extending from Rutherford County northeastward to the Yadkin River—a distance of about 95 miles. The development of the industrial minerals in North Carolina is a good example of the importance of progressive research to determine local resources, their technology and uses. Much has already been accomplished and much remains to be done. Ill—SAND AND GRAVEL DEPOSITS North Carolina has a fair amount of sand and gravel in the water-formed deposits. These deposits, are fluviatal (streams), fluviomarine (streams and sea), marine (sea), and lacustrine (lake) in origin. In the Mountain and upper Piedmont regions, de-posits occur along the bottom or flood plain areas of the streams. In the lower Piedmont and Coastal Plain, deposits are rather widespread and roughly follow the old shore line. The best deposits are found in the beach terrace areas. WINTER, 1947 THE E. S. C. QUARTERLY PAGE 21 The commercial sand consists chiefly of quartz; the chief impurities are feldspar, mica, hornblende, and clay, the products of the weathering of the crys-talline rocks, and organic matter. Most of the impur-ities are eliminated when the material is washed and screened. The lower Piedmont and Coastal Plain gravels are composed of more or less rounded quartz pebbles which are derived from the quartz veins that cut the pre-Cambrian rocks to the west of the fall line (the western boundary of the Coastal Plain). The round form is due to the wearing caused by stream and wave action before and during deposition. The gravels of the upper Piedmont and Mountain sections are composed of quartz pebbles and frag-ments of older crystalline rocks. These gravels are also more or less rounded and vary in size from coarse sand to large-sized boulders. These gravels must be crushed as well as screened before they are suitable for commercial use. The most important sand and gravel deposits cross the State in a northeast-southwest direction and lie east of the fall line. The richest deposits occur where the larger rivers enter the ocean. Geologically they belong to a formation formerly known as the "Lafay-ette," of Pliocene age. This formation is well devel-oped in parts of Anson, Richmond, Moore, Harnett, Johnston, Nash, Halifax and Northampton Counties. The important deposits are near the Pee Dee River in Anson County; well distributed over Moore County, along the Cape Fear River near Lillington in Harnett County and, in Halifax and Northampton Counties along the Roanoke River. All of these de-posits are of varying value and have been exploited to some extent. VALUABLE GRAVEL IN PEE DEE AREA The Anson County deposits occur in lenses and beds from 10 to 40 feet thick, chiefly on the west side of the Pee Dee River, where the "Lafayette" forma-tion overlies the crystalline rocks. In most places the deposits are covered by 10 to 20 feet of overbur-den. They cover about 300 acres, part of which have been worked. The gravel is a high grade material consisting of quartz and quartzite pebbles mixed in sand and clay. The pebbles range in size from three inches in diameter down to fine sand. Six miles southeast of Wadesboro and one mile east of Bennett Station some small deposits, containing clay, sand, and gravel, are found. The average depth is from two to six feet and covers about 30 acres. In the eastern part of the County small lenses of sand and gravel are found in the Coastal Plain formations, south of Wadesboro. The "Lafayette" formation also contains extensive sand and gravel deposits in Moore County. One de-posit has an irregular outline, varying in width from i/2 to 1^2 miles, and extends for four or five miles southeast of Carthage. The deposit consists of rounded pebbles of quartz and quartzite, and sand ; it occurs as a covering 1 to 12 feet thick along the tops of the highest hills and ridges. Deposits also occur west of Carthage. These range in width from '/•> to 2 miles and are about 10-12 miles long. They consist of semi-rounded and crushed quartz mixed with soil, sand, and clay, and occur along the tops of hills and ridges. In another area to the southeast of Carthage the gravel consists of white to orange-colored quartz and quartzite pebbles, well-rounded and mixed with a quartz sand. The gravel is clean and easily washed. In places the deposits run as high as 70 percent grav-el, not counting sand. SAND AND GRAVEL NEAR CAPE FEAR In Harnett County, just east of the fall line and along the Cape Fear River rich and extensive deposits occur. The greatest development has been between Lillington and the River. The deposits occur in hills and ridges and range in depth from 10 to 40 feet. They consist of gravel pebbles composed mainly of quartzite, quartz, and sand grains that are almost pure quartz. The gravel and sand are easily washed and cleaned. In many parts of the deposit the amount of foreign matter is not over two or three percent. The washing opera-tion produces concrete gravel, cementing gravel, roofing gravel, concrete sand, and filter sand. In some parts of the deposit an excess of clay makes those portions not of a washable grade. These, however, have been utilized for roads and streets, particularly at nearby Fort Bragg. Other deposits are situated southwest and northwest of Lillington. Some of these contain a high proportion of clay, but others contain a satisfactory material; all of these have a depth much less than that of the principal deposit between Lillington and the Cape Fear. Johnston County is crossed by the "Lafayette" ter-race formation and deposits of gravel are found along the Neuse River just west of Smithfield and near Selma. Good deposits of sand occur about two miles west of Selma and about one mile east of the Neuse, on a low flat ridge that rises a few feet above the river valley. A foundry sand is found there, overlain by 12 to 15 inches of soil. Below this is a bed of filter sand which at a greater depth grades into a clayey gravel. About one mile west of Selma is a very good gravel deposit. The geology there consists of shal-low deposits of sand, clay, and gravel, with exposures of older basement rock. This gravel has been used as railroad ballast; the more sandy, porous grades were sought and the clayey grades were left in the pit. The material is mainly quartzitic and quartz and ranges in size from one inch down to a coarse sand. Some of the clayey gravel has been used with consid-erable success in local road construction. The gravel deposits around Smithfield are shallow—3 to 10 feet deep—but they are of a good quality and are locally important. SAND PITS NEAR NEUSE RIVER Lenoir County has been extensively prospected for sand. The deposits are rather large and rich. The Neuse River valley is about three miles wide in the vicinity of Kinston and is filled with plenty of good sand which yields several grades, ranging in size from PAGE 22 THE E. S. C. QUARTERLY WINTER, 1947 small gravel to ordinary plaster sand. It is angular and remarkably free from mica and organic matter. A number of sand pits have been in operation in the Kinston area ; one of these covers 3 to 4 acres and has an average depth of 20 feet. The finer product has found a utilization as sheet asphalt filler. In Edgecombe County sand and gravel occur along the streams and in the old stream valleys. The most important deposits occur along the Tar River. Near Tarboro where this stream makes a long bend there is a sandbar which supplied a great deal of high grade sand. At each freshet the sandbar is rebuilt thereby effecting a continuous supply of sand. Also just to the southeast of Tarboro a very good building sand is found. The sand is composed chiefly of quartz, very clean and free of mica. One mile north of Tarboro on the inside of a bend of the Tar River a very exten-sive deposit of a clean, hard, angular sand is found, ranging in depth from 4 to 10 feet and covering sev-eral acres. Halifax and Northampton Counties have rather extensive but not deep deposits of gravel. The "La-fayette" formation is rather well marked in the sec-tion around Thelma and near Weldon. In this area and especially along the old valley of the Roanoke River there are large deposits of gravel. Near Thel-ma there are gravelly hills that are parallel to the river valley. The topography is rolling to hilly and is deeply cut by several small streams. The gravel shows a depth of from 15 feet on the tops of the ridges to 4 feet along the hillsides and valleys ; it con-sists of well-rounded quartz and quartzite pebbles in a matrix of sand and clay. Although there are sev-eral other localities in these counties the most im-portant is near Garysburg where the gravel occurs along a rolling and hilly area on the north edge of the Roanoke River Valley. A modern washing plant has been in operation there for some years. The gravel ranges in depth from 15 to 20 feet and consists of both sand and clay gravel. The gravel itself is a quartz-quartzite material ranging in size from 3 inches in diameter down to coarse sand. The average size is from 11/2 inches to 14 inch. Wake County has little gravel and sand. A few small deposits are found along the fall line and near streams. There is one good deposit of crushed quartz near Garner. In the southwestern section are de-posits of gravel that are of local importance. None of these are great in extent or depth. The gravel consists mostly of a mixture of water-worn pebbles in clay. The pebbles are quartz and quartzite, com-prising an excellent road material. GRAVEL DEPOSITS ON PIEDMONT STREAMS In the western counties there are no extensive sand and gravel deposits, but there are many local ones which may be worked commercially. The gravel de-posits of these counties occur principally along the main stream valleys and in the stream terraces, caused by the streams meandering across the broader valleys. The most outstanding deposit is in Bun-combe County near Swannanoa, where a modern plant of the Grove Stone Company has been producing sand and gravel for many years. Most of the counties along the foot of the Blue Ridge Mountains, as Polk, Rutherford, McDowell, Burke, Caldwell, Wilkes, and Surry, have stream gravel deposits. These gravels are composed of quartz, quartzite, and rounded fragments of the old crystalline rocks. They range in size from sand to large boulders. In most of the deposits the gravel has to be crushed, washed, and screened before being suitable for the various trades. No real good quartz gravel deposits, as those just below the fall line, are found. Only occasionally are deposits found where the gravel is uniform. As a result of this condition the deposits have not been worked to any extent. Then too there are so many exposures of rocks of dif-ferent varieties which are easily quarried for the various trades. Along the Yadkin River from the boundary of For-syth County westward to North Wilkesboro and be-yond there is an abundance of sand which has been worked at several places. Most of this sand was put down in the 1916 flood. Much of it is too fine for ordi-nary concrete use. However, locally, there are de-posits that are very good. Besides concrete sand, much fine sand for sheet asphalt and filler can be ob-tained. In the mountain district some exploitation of com-mercial sand and gravel is in Burke County, especial-ly along Silver Creek; on the headwaters of this stream a great deal of quartz is mixed in the gravel but no true quartz gravels are found. In some places the material is quite angular although in others it is well rounded. Other localities, where the most im-portant deposits occur, include along the Catawba River in Iredell County, and between Old Fort and Marion. Rounded fragments of crystalline rocks constitute extensive deposits along the river bottoms between the Broad and Second Broad Rivers in Ruth-erford County. For the ten year period of 1935 to 1944 inclusive the average annual production of sand and gravel in North Carolina was 2,659,356 short tons ; the average annual value was $1,265,736. The maximum produc-tion was in 1941 and amounted to 4,473,297 short tons, valued at $2,345,165. REFERENCES 1. Bryson, H.

QUARTERLY PAGE 23 Summary of Provisions of Amendments to U. C. Law By W. D. Holoman, Chief Counsel, ESC EMPLOYMENT SECURITY COMMISSION IS NEW NAME OF THE FORMER UCC "Employment Security Commission of North Carolina" and "Employment Security Law" now take the place of the former "Unemployment Compensation Commission of North Carolina" and the "Unemployment Compensation Law," the change in name having heen provided in an amendment in-troduced in the General Assembly by Senator Lee B. Weath-ers of Cleveland County and enacted by that body. The change in name was considered as more nearly re-flecting' the activities of the two principal divisions of the Commission, since both the North Carolina Employment Service Division and the Unemployment Compensation Divi-sion deal with employment security. Several states have made the change in recent years, indicating a trend toward a name which comes closer to describing the activities of the Commission. Change in the name became effective upon passage of the amendment, but provision was made by which the Commis-sion is authorized to continue to use its old forms, checks, letterheads, stationery and other printed materials bearing the former name until they become exhausted. All new sup-plies will bear the new name. The new amendment makes several provisions, includ-ing the following: The Commission shall cooperate with other state agencies to oppose federalization of state employment security pro-grams. The Commission may enter into reciprocal agreements by which wages earned in covered employment in more than one state, if producing less than the eligible amount, may be combined and the individual paid benefits, to be charged to the partially pooled account, and not to any employer. If an employer operating in more than one state pays an individual $3,000 for services in another state prior to his employment in North Carolina, and had paid unemployment compensation taxes to such other state, such individual's wages earned in this State; would be exempt. The bonds of the Commission's field representatives are increased from $2,000 to $3,000 to conform to the amounts for other state employees in comparable positions. An unemployed person is disqualified to draw benefits under the E. S. Law if he asserts his right to benefits against another state or the Federal Government, unless such claim is filed under a reciprocal agreement plan with another state. Two amendments recently passed, relating to reciprocal agreements, are deleted to make the law conform to changes made by this act. EARLIER AMENDMENTS The first Unemployment Compensation Law in North Carolina was passed at a special session of the General Assembly in December 1936. The original law was prepared primarily from suggested drafts furnished by the Social Security Board. Due to the urgency of the passage of this Act by the special session, the members of the Legislature and the officials sponsoring it, did not have an opportunity to give its provisions the careful consideration which an Act of such proportions required. At that time the over-all Social Security Program, and particu-larly the Unemployment Compensation Program, which was a part thereof, constituted a new experi-ment in this country. The only precedents which the Federal Government and the respective states had to follow were those precedents established in European countries. As this program was in its infancy it could not be expected that the original law would be adequate to meet the needs of this state. Since that time, there-fore, it has been necessary to amend the original law to meet changing conditions and to remedy de-fects found from time to time. It has also been necessary to make changes relative to a more efficient administration of the program in North Carolina. At each session of the Legislature since the adoption of the original law certain amendments have been necessary, and the year 1947 is no exception. The amendments suggested by the Commission and passed by the 1947 Legislature, in general are not controversial, but primarily deal with a more efficient administration of the law, and were neces-sary by reason of certain changes by Congress in the Federal Unemployment Tax Act. It is needless to comment on the minor adminis-trative amendments. However, a few changes de-serve comment as they affect workers and employers generally throughout the state. SPECIAL ADMINISTRATIVE FUND A new fund was created in the State treasury which was designated as a Special Unemployment Compen-sation Administration Fund. It was provided by the amendment that subsequent to June 30, 1947, all interest and penalties collected from employers under the Unemployment Compensation Law shall be paid into such special fund. No part of such special fund shall be used or expended in lieu of any Federal funds made available to the Commission for the administration of the law. Out of this Special Un-employment Compensation Fund will be paid all re-funds of interest erroneously collected by the Com-mission provided such interest was paid into the fund. Prior to the adoption of the amendment, if the So-cial Security Administration found that any amount had been expended from the Unemployment Compen-sation Administration Fund for any purposes other than those found necessary by the Social Security Administration, the State was required to replace such funds, and it further required the Governor to submit to the Legislature a request for an appro-priation to replace such amounts. As an example, an employee who is paid the entire month's salary on the 25th of the month might fail to report back to work after that date. It is obvious that such em-ployee is overpaid. If, after the Commission ex-hausts its efforts to collect such amount and fails, then the Legislature would be required to appro-priate an amount so that the Unemployment Com-pensation fund might be reimbursed. The special fund would take care of such contingencies and the Commission could reimburse the Unemployment Compensation Administration fund from the special fund. MARITIME SERVICES COVERED Several amendments were passed relating to Mari-time coverage to bring the State law into conformity PAGE 24 THE E. S. C. QUARTERLY WINTER, 1947 with a recent Federal Amendment. On August 10, 1946, Congress passed an amendment to the Federal Unemployment Tax Act, effective July 1, 1946, pro-viding that salaries and wages paid for services per-formed by the officers or members of a crew in con-nection with the operation of an American vessel, are taxable under the Federal Unemployment Tax Act. The amendment to the North Carolina Law brings under its coverage like services performed on such vessels when the operations are controlled from an office located in the State of North Carolina. These amendments conform to the Federal Act and tax only the same type of services as does the Federal Act. An individual who maintains an operating office in this State from which such individual supervises, manages, directs, and controls the operation of an American vessel operating on the navigable waters within or within and without the United States, is brought under the State law. TIPS NOT COUNTED AS WAGES Under the Unemployment Compensation Law wages means all remuneration for services from whatever source and the term wages, prior to a recent amendment, has been defined by the Act to include gratuities customarily received by an indi-vidual in the course of his work from persons other than his employing unit. This definition of wages, therefore, made it necessary for the Commission to attempt to tax tips received by individuals from per-sons other than the employing unit just as if such amounts had been paid by the employing unit. The employers throughout North Carolina found it prac-tically impossible to keep account of the amount of tips received by individuals in their employ as the individuals did not report the tips to the employing unit. So, it was practically impossible to administer that portion of the law. A recent amendment de-leted from the definition of wages those gratuities which constituted tips. Such amendment should meet with the whole-hearted approval of all em-ployers who are faced with such a problem. REMUNERATION TAXED IN YEAR PAID Another amendment was adopted in which all em-ployers should be particularly interested and which they should bear in mind when preparing any and all future returns. This amendment amends Section 96-9, subsection (a), paragraph (2) of the Unem-ployment Compensation Law, by providing that from and after January 1, 1947, the term wages shall in-clude the first $3,000 paid by an employer to an employee during a calendar year without regard to the year in which the employment occurred. Prior to the amendment remuneration not in excess of $3,000 was taxable with respect to the year in which it was earned regardless of the year in which it was paid ; therefore, subsequent to January 1, 1947, em-ployers in preparing their returns should report and pay contributions only on remuneration up to $3,000 which has actually been paid employees during the calendar year irrespective of the year in which the employment occurred. SIMPLIFIES VOLUNTARY CONTRIBUTIONS Prior to the recent amendments, the Unemploy-ment Compensation Law provided, in its Employer Experience Rating plan that an employer could make a voluntary contribution, in addition to the contri-butions required under the law, for the purpose of reducing his tax rate for the following year, but it was necessary for such voluntary contributions to be made not later than July 31 of the calendar year in order for such contribution to be taken into con-sideration in computing the tax rate for the follow-ing year. Under the statute, prior to the amendment, it was impossible for the employer to know what voluntary contribution it would be necessary for him to make in order to get the desired reduction, as he was not cognizant of what charges had been made to his reserve account for the three months' period ending July 31. The law, as amended, places upon the Commission the responsibility of notifying an employer, as soon after July 31 as possible, of all charges made against his reserve account for the three months preceding August 1, so that such em-ployer can accurately compute the amount of volun-tary contribution necessary to reduce his rate. As a result of the amendment the employer may, within ten days after the mailing of such notice of charges against his account by the Commission, make con-tributions which will be credited back as of July 31 so that he may get the benefit of the reduced rate. This will materially benefit those employers who de-sire to make a voluntary contribution for the purpose of getting a reduced rate for the following year. SPECIFIES DATE OF STARTING SUIT No suit or proceeding for the collection of unpaid contributions may be begun by the Commission after five years from the date on which such contributions became due; this in effect is a five-year statute of limitation on the collection of unpaid contributions. An amendment was adopted recently for the purpose of defining when a proceeding shall be deemed to have been instituted or begun. Under the amend-ment a proceeding shall be deemed to have been in-stituted upon the date of the issuance of an order by the Chairman of the Commission directing a hearing to be held to determine liability or non-liability, or upon the date notice and demand is mailed by regis-tered mail to the last known address of an employing unit. Since the adoption of the amendment there can be no question raised by any employer or em-ploying unit, or interested party as to when a pro-ceeding is deemed to have begun as it relates to the five-year statute of limitations. THAWS FROZEN CREDITS In 1941 the General Assembly amended the Un-employment Compensation Law to provide that wage credits of workers entering military service would be available to the workers when they were dis-charged. The purpose of such amendment in 1941 was to freeze wage credits so that the returned veteran would be entitled to some unemployment benefits from prior credits after discharge from WINTER, 1947 THE E. S. C. QUARTERLY PAGE 25 military service and until he could find work and readjust himself. Subsequent to the passage of such amendment the Servicemens Readjustment Allow-ance Act was passed by Congress and under the Act, veterans who are unemployed through no fault of their own, after discharge from military service are entitled to $20 per week for a maximum of 52 weeks. It was felt, therefore, that since the veterans' rights were so well taken care of by the Servicemens Re-adjustment Allowance Act, which the Unemployment Compensation Commission of this State is adminis-tering for the Federal Government, that their credits should no longer be frozen under the North Carolina Law, therefore, the freezing provisions above-referred to were deleted from the law by a recent amendment. Before the amendment to delete such freezing provisions was offered to the Legislature, the Legislative Committee of the American Legion was notified that an amendment of that nature was contemplated and no objections were raised by that committee. Under the law as amended a veteran who is unemployed through no fault of his own, who is able and available for work, and otherwise eligible for benefits, may draw readjustment allowances, which are paid by the Federal Government, for a maximum of 52 weeks. If after exhausting the benefits available for him under the Readjustment Allowance Act, he is still unemployed, he may then draw benefits under the Unemployment Compensa-tion Law of North Carolina, provided that he has built up wage credits in a base period subsequent to his return from military service. CLAIMANT MUST SEEK WORK There is another amendment which should be of interest to employers and employees alike. To be entitled or eligible to receive any benefits under the Unemployment Compensation Law, it is necessary for an individual to show to the satisfaction of the Commission that he has registered for work at a public employment office; that he has filed a claim for benefits, and that he is able to work and available for work. A recent amendment adds a proviso to these eligibility conditions which provides that no individual shall be deemed available for work unless he shows to the satisfaction of the Commission that he is actively seeking work. This puts a definite responsibility on the unemployed individual to go out and try to find a job himself. Prior to the amend-ment the mere fact that an individual had registered at an employment office and filed a claim, and stated that he was able and available for work, was taken as evidence of his availability. Now, it will be neces-sary for him to show that he has made real efforts on his own behalf to secure employment. REPEALS SUBCONTRACTOR CLAUSE The General Assembly saw fit to repeal that sec-tion of the law which is commonly known as the subcontractor clause. This provision of the law is Section 96-8 (f) (8) of the General Statutes of North Carolina. The repeal of the subcontractor clause was not suggested to the General Assembly by the Commission. That section of the law was the one under which contractors or subcontractors hav-ing a contractual relationship with a principal covered employer, were held liable even though they did not have as many as eight or more individuals in their employment. Such section also provided that even though neither the principal nor the subcon-tractor had as many as eight individuals in the respective employ of each, and by combining the employment record of each, they would jointly have eight or more, then because of such contractual re-lationship, both the principal and the subcontractor were liable. Since the repeal of this section of the law, it will be necessary for the Commission to more closely scrutinize the relationship between the prin-cipal employer and contractor or subcontractor in order to determine whether or not the contractor or subcontractor comes within the definitions of em-ployment. No changes were made in the coverage under the Unemployment Compensation Law except as to maritime workers. No changes were made in re-spect to increasing weekly benefit amounts, nor in respect to the extension of weeks of unemployment benefits. It is felt that the amendments as a whole were constructive amendments. • MARBLE, GRANITE, CRUSHED STONE In 26 North Carolina counties various types of granite, marble and crushed stone are produced in commercial quantities and in 1945 the UCC records show that 2,615 covered workers were engaged in this industry. The record follows : Employment Average—1945 Alleghany—Miscellaneous Non-Metalic Mining 2 Anson—Sand and Gravel : 70 Avery—Miscellaneous Non-Metalic Mining 130 Buncombe—Sand and Gravel Quarries 3 3 Buncombe—Miscellaneous Non-Metalic Mining-- 761 Cherokee—Dimension Stone (Marble) 50 Cherokee—Miscellaneous

Cover for Winter, 191fl—North Carolina's Capitol, located in
the center of a six-acre tract, around which was laid out the
City of Raleigh as a State Capital, of Grecian Doric design
copied from the Temple of Minerva (The Parthenon) in
Athens and with other Grecian and Roman architectural
features, was designed and built by David Paton, Scotch
architect, who was brought to Raleigh to design and super-vise
its construction. Seven years, 1833-1840, were required
for its completion, at a total cost of $531,674.46, which was
appropriated by seven annual sessions of the General As-sembly.
The stone of which it was constructed was quarried
within one mile of the Capitol, largely by convict labor, and
was hauled to Capitol Square on a narrow-gauge railroad
track from the quarry to the Square. The stone is gneiss,
particularly suitable for construction of large buildings.
"The old rock quarry," long a deep hole caused by quarrying
the stone, partially filled with water for 100 years and located
south-east of Capitol Square, was finally filled in during the
early 1940s.

OUR NAME CHANGES TO "THE
E.S.C. QUARTERLY": NEW SSZE
Because the recent session of the North Carolina
General Assembly changed the name of the "Unem-ployment
Compensation Commission of North Caro-lina"
to the "Employment Security Commission of
North Carolina" and the "Unemployment Compen-sation
Law" to the "Employment Security Law," the
name of "The U.C.C. Quarterly" is also changed to
"The E.S.C. Quarterly."
Articles in this issue were written before the
change was made, so wherever the initials "U.C.C",
or the longer name for which they stand, appear, it
means "E.S.C." or Employment Security Commis-sion.
With this issue the size of our quarterly changes,
but only in one respect—the overall size, which is
reduced slightly. Type sizes and type pages remain
the same. Only the margins are slightly reduced.
N. C. GRANITE PRODUCED IN
YEAR 1945 VALUED AT $312,794
"The South, a Leader in Stone Production" is the
title of an article written by Oliver Bowles and Rob-ert
P. Willing and, with eight illustrations, occupies
several pages in the February issue of Manufactur-ers
Record, Baltimore, Md.
Three of the illustrations are from North Carolina.
One is the exterior view of the U. S. gold depository
at Fort Knox, Ky., made of Mount Airy granite;
another is of a big granite lathe at the Mount Airy
plant, turning a round granite post; and the third
shows a stack of granite being crushed for highway
construction, with the information that four quarries
and four plants of one North Carolina company (not
identified) produce gravel and crushed stone.
For many years, the authors relate, the South has
been one of the country's leading stone producers.
Figures based on the report of the Minerals Year
Book of the Bureau of Mines, the South produced
nearly 30 percent of the nation's total in 1945, or
43,999,610 short tons valued at $53,033,607. Pro-duction
includes ornamental stone such as that used
in Washington's magnificent structures and other
dimension stone for building, as well as crushed and
broken stone used in lime and cement and highway
construction, the article relates.
Reference is made to the granite operations at
Mount Airy and near Salisbury, the marble develop-ments
in Cherokee County and crushed stone activi-ties
in many parts of the State. One paragraph in
the article reads as follows
:
"North Carolina also produces considerable quantities of di-mension
granite near Mount Airy in Surry County near the
northern State boundary. The cut stone produced in this re-gion
is widely used in bridges, dry docks and in large build-ings.
An extensive market likewise has developed for the
smaller fragments—ashlar—for constructing moderate priced
homes. Both quarries and mills at Mount Airy are equipped
with modern machinery. In addition to Surry County, granite
is found in Rowan, Davidson, Wake and Henderson Counties.
In 1945 North Carolina produced 13,990 short tons of granite
valued at $312,794."
WINTER, 1947 THE E. S. C. QUARTERLY PAGE 3
Mount Airy Granite Famous for Buildings and Monuments
By M. R. Dunnagan, hifovulational Service Representative, ESC
About 75 years ago, one Robert S. Gilmer purchased
a large farm in Surry County, on a portion of which
part of the Town of Mount Airy is now located.
Within the farm area, about two miles from the site
of the Town of Mount Airy, was a huge rock forma-tion,
known locally as "The Rock," about 50 acres in
area and in appearance something like a huge oyster
shell. The farm was bought at a "per acre" rate,
and, as it was not suitable for farm purposes, "The
Rock" was not counted in the acreage, but was given
to the purchaser without charge as a part of the farm
area.
That part of the farm which was then considered
worthless is now famous as the largest open-faced
granite quarry in the world, with 80 acres of work-able
granite exposed. From its surface many thous-ands
of tons of granite have been quarried and sold
for millions of dollars for use in public buildings,
bridges, homes, memorials, and mausoleums in prac-tically
every state in the nation.
In 1889, while the Cape Fear and Yadkin Valley
Railroad was being built from Wilmington to Mount
Airy, an English-born family named Woodruff, then
living in Greensboro, had the contract for building
the railroad stations between Greensboro and Mount
Airy. Four sons in this family, William, George,
Thomas and Frank, lived in Mount Airy while com-pleting
the construction work on that end of the line.
Seeing possibilities in "The Rock," whose principal
use up to that time was as a location for picnics for
the people in the surrounding countryside, these
Woodruff brothers purchased it and some of the sur-rounding
land from Mr. Gilmer for about $5,000.
They set about quarrying the granite immediately
upon purchase in 1889, and several years later in
1904, The North Carolina Granite Corporation was
formed.
Around 1910, John Davis Sargent, an experienced
quarryman from Vermont was brought to Mount
Airy to operate the quarry. Mr. Sargent soon saw
the possibilities of cutting stone for buildings, monu-ments,
etc., and leased from the Woodruff brothers
the cutting sheds which they had been operating
along with the quarry. Mr. Sargent then formed
the J. D. Sargent Granite Co. on his own and began
cutting the granite into dimension, monumental, and
other types of stone. The J. D. Sargent Granite Co.
bought the rough granite from the Woodruff's cor-poration,
which Mr. Sargent continued to run for
them.
It was not long before the young cutting company
became the largest part of the operation, and having
proved itself was taken into the larger corporation
with Mr. Sargent as president of the North Carolina
Granite Corporation.
Note—Information for this article was furnished largely by John P. Frank,
president, N. C. Granite Corp., Caleb H. Haynes, Mount Airy, N. C, and from
an article published in "Rock Products," McLean-Hunter Pub. Corp., Chi-cago
6, III.
Shortly after this Francis H. Fries and W. F.
Shaffner, bankers of Winston-Salem, and Charles B.
Keesee, a banker in Martinsville, Va. became inter-ested
financially in the corporation, and they together
with Mr. Sargent formed the "big four" stockhold-ers,
after buying out the interests of all other stock-holders,
including the Woodruff brothers. Messrs.
Fries, Shaffner, and Keesee had come to know of the
quarry through dealings, and vacations spent at
White Sulphur Springs, near Mount Airy.
"BIG FOUR" DEVELOP QUARRY
This "big four," sparked by the dynamic Mr. Sar-
KILLED GENERAL, LATER SHARPENED
TOOLS TO CARVE MONUMENT TO HIM
The State of Pennsylvania, during the years after the War
Between the States, decided to erect a monument to its illus-trious
sons, and gave the contract to the owners of the Mount
Airy granite quarry for the stone, the Ionic columns and the
heroic statues of the citizens it was to honor. The material was
produced and the monument was erected at Gettysburg, com-memorating
that famous battle and rising high above the
battleground.
When most of the figures of noted Pennsylvania men had
been completed or were Hearing completion, a resident of
Pennsylvania came to North Carolina on other matters. He
knew of the plans for the monument and visited the quarry
more than once. Taking others to see the work, he pointed
out the various distinguished men represented. He pointed to
one statue, explaining that it was of General Reynolds, of
Pennsylvania, and that he had been killed in the Battle of
Gettysburg.
"I think it is entirely appropriate," spoke up one of his
guests, "for Pennsylvania to have this work done in North
Carolina, in Surry County and here at Mount Airy. For it
was," he continued, "a Surry County and a Mount Airy man
who killed General Reynolds. In fact, the man who killed
General Reynolds is the man who is now and has been for some
years in charge of making and sharpening the tools with which
the statue of General Reynolds was carved."
And, as the man who had shot General Reynolds was pointed
out, as he went about his forge working on tools used in the
quarry, the story was unfolded. It has been picked out of the
blacksmith, who previously had operated a blacksmith shop
near Dobson, by friends who knew something of the incident.
The blacksmith and tool sharpener was so modest that they
had to keep picking and questioning to get him to relate what
happened.
Sharpshooter Frank Wood and Private Cox, it developed,
were in the thick of the fight at Gettysburg. In some way they
became separated from their company and found themselves
in a railroad cut, right in the line of fire. Nearby, they saw
a rail fence and ducked to it for protection. From this cover
they surveyed the scene. A few hundred yards away they saw
on a big horse a man, gold braid on his hat, epauletts on his
shoulders, scabbard and boots with spurs and other accoutre-ments
speaking of high rank. He was standing up in his stir-rups,
waving his sword and shouting to his men.
"Give them hell, boys. Give them the grape. Give them hell.
Give them the grape."
Private Cox asked Sharpshooter Wood if he couldn't pick
that man off at that distance. Wood wasn't sure, but thought
he could. He estimated the distance, raised the sights on his
musket, took deliberate aim, and fired. The man fell from his
horse, dead.
That was General Reynolds and Sharpshooter Wood, back
home and a blacksmith for several years, went with the Mount
Airy granite firm to make and sharpen tools, and produced
the tools with which the statue of General Reynolds was cut
and chiseled and formed. (See picture of Pennsylvania Monu-ment,

gent, actually and figuratively, put Mount Airy gran-ite
on the map of most states in the Union. Novel
methods of advertising and publicizing this granite
were promoted by Mr. Sargent and his associates.
By-products of the quarry were utilized and many
new uses for granite from the screening to dimension
blocks were devised and developed.
During this time the "big four" would take into
the firm promising young men, test them, give them
positions of importance and trust, and when they
proved their mettle, allow them to purchase stock,
or, in some cases, give them stock to increase their
interest in the success of the firm.
One of these employees was John Prather Frank,
son of Methodist missionaries to Japan. Mr. Frank
was taught by his parents in Japan. His entire
formal schooling included one year in high school at
Mount Airy, two years at Trinity Park school on the
Trinity College campus, and four years at Duke Uni-versity.
He specialized in business administration.
After finishing college at 20 years of age, Mr. Frank
applied for a job at the quarry, was hired at $15 a
week and paid $20 for his second week. He started
in the drafting room, worked there about eight
months and was transferred to the business office,
doing clerical work.
After four years Mr. Frank was elected assistant
secretary-treasurer of the firm. In 1935 he was pro-moted
to secretary-treasurer, in 1940 to vice-presi-dent,
and in July, 1945, following the death of Mr.
Sargent, was elected president of The North Carolina
Granite Corporation.
Chris Binder was brought into the business in 1916
by Mr. Sargent, who recognized his ability as a cut
stone man. Mr. Binder's experience was gathered
from operations in New England, Pennsylvania, and
Georgia. It was not long before he became Manager
of the Cut Stone Department of the corporation, and
has operated that department successfully for the

at present.
COMPOSITION AND CONDITIONS
"The Rock" at Mount Airy still has the appear-ance
of a monstrous oyster shell, even though prob-ably
50,000,000 cubic feet of granite have been re-moved.
During periods of normal operations about
3,000 carloads are removed each year, yet it is esti-mated
that 500 years of quarrying at that rate will
not exhaust the supply. The granite surface is still
above or even with the surrounding land area—no
underground or below surface operations.
Mount Airy granite is described as a biotite gran-ite
of medium grain, almost white, but with a light
grey appearance. The feldspar, principal constitu-ent,
is white; the quartz is blue-gray and the small
amount of mica is black. All of these parts are even-ly
distributed throughout the entire deposit, result-ing
in a remarkable uniformity.
Tests are interesting. They show that a cubic
foot of this granite weighs 165 pounds; that the
crushing strength per square inch is 23,069 pounds.
They also reveal that the water absorbed by a cubic
Well-knotvn Arlington Memorial Bridge, connecting Arlington
Cemetery and the City of Washington. Bridge and approaches
contain 685 carloads of finished white Mount Airy granite.
foot of this granite is only 0.33 of a pound. This
means that if 165 pounds of this granite were sub-merged
in water, it would absorb less than one-third
of a pound of the water. Its crushing strength and
water resistant qualities are pointed to as particu-larly
desirable in the construction of large buildings
and bridges.
The average person will be surprised at the sim-plicity
of the quarrying processes. Dynamite is
never used for quarrying. Results of its use would
be disastrous. Its force would shatter and crack the
granite, causing flaws in the blocks. Nor is com-pressed
air used in the lifting process, although it is
used extensively in granite quarrying and cutting.
Mother Nature, with her heat expansion in sum-mer
and cold contraction in winter, is a most valu-able
worker at this quarry. Her chief ally and aide
is one of the oldest of explosives, black gunpowder,
and this is used sparingly. The splitting quality of
the granite aids in the quarrying. The grain of the
granite is horizontal and a light force starts a split
which gives a smoother surface than is achieved in
splitting boards. Also, regular and even force ex-erted
through the principle of the wedge gives a
smooth and remarkably even perpendicular split. It
is the same principle used by the ice man who marks
a chunk of ice with his axe, gives a harder stroke and
a smooth, even, 50-pound piece of ice separates itself.
So, when a sheet of granite is needed for large cut
or dimension stone construction, a hole, about 2V->
inches in diameter, is drilled perpendicularly into the
granite four to eight feet deep. A small, very small,
charge of black powder is placed at the bottom of
this hole and exploded. The explosion merely starts
a small horizontal crack in all directions from the
bottom of the hole. A slightly larger charge of pow-der
is exploded, extending this crack or split in the
granite. Another slightly larger charge is exploded,
extending the split still further, but not damaging
the granite. This process is continued until the hori-zontal
split is as large as is needed, or it is left for
HUGE CUT STONES AND FINE GRIT
COME FROM MOUNT AIRY GRANITE
The wide range of sizes and wider range of uses for Mount
Airy granite is shown in the following list:
Cut Stone—Huge blocks, shaped and sculptured, form mauso-leums,
monuments and memorials, columns, heroic figures
and other decorations for buildings.
Dimension Stone—Used in constructing buildings, bridges
and other large structures.
Paving Blocks—Usually 4y2 x5xl0 inches or size desired, and
Street Curbing, usual or unusual sizes.
Flagstones—Made from quarry blisters, from one to five
inches thick, form artistic, rough natural stones for walkways
in gardens, floors of open places and other bases.
Rough Ashlar—Suitable for schools and churches, 6x9x4
inches, and larger, ready for use as it comes from the quarry.
Rubble—Needs shaping, before use in building walls.
Rip-Rap—Odd sizes of quarry refuse, suitable for sea walls,
embankments and aggregates for heavy concrete foundations.
Crushed Stone—Crushed to various sizes. One machine re-duces
granite to 2% inches or down to one inch, screened for
size. Another crusher reduces it further. It is used as road
material and concrete aggregates, 2V2 inches and down; for
roofing gravel, % to % inch; aggregates for making concrete
blocks and lamp posts; station yard and track ballast, 14 inch
and down; poultry grit, in sieye sizes for turkeys and old, young
and baby chicks.

the heat of the sun and the cooler nights, or the cold
of winter to continue the splitting process.
By "soundings" on the surface, that is, tapping the
granite with a hammer, it is possible by the sound
produced to tell how far the split extends in all direc-tions
from the original base of the hole. If it is dis-covered
that the split is not extending in the direc-tions
desired to get the sheet (if four to eight feet
thick granite can be called a sheet) , then a new hole
is drilled further along in that direction to a similar
depth and black powder is exploded to extend the
split already started. This undersurface split can
and sometimes is extended over an area including
several acres. So, it is possible to split off a sheet
four to eight feet thick and acres in area.
PEEL OFF HUGE GRANITE SHEETS
Naturally, such large -sheets cannot be handled.
When the area is sufficient for current needs, holes
are drilled perpendicularly a few inches deep and a
few inches apart. The wedge principle is used to
separate the entire sheet of the blocks. Wedges are
driven into these shallow holes and tightened grad-ually.
Due to the markings made by the drilled
holes, the granite splits perpendicularly almost as
regularly and evenly as it does horizontally. The
heat and cold expansion and contraction also help
this process of cutting the blocks of granite to the
size needed.
Sizes of granite blocks are limited to capacity of
railroad cars. It is possible for cars to carry a max-imum
of 100 tons, although 50 tons is nearer the
usual car. Twelve cubic feet of granite weigh about
a ton. Maximum sizes of blocks are 40 feet by 5 feet
by 5 feet. More usual sizes are 30x4x4 feet.
The Arlington Memorial Bridge, connecting Wash-ington
and Arlington Cemetery over the Potomac
River, is one of the largest masses of Mount Airy
granite. In its construction 685 carloads of granite
were used. The weight of this granite is about

30,000 tons. A solid train of freight cars sufficient
to haul the granite used in this bridge would be more
than four miles in length.
The Mississippi River bridge at Memphis, Tenn.,
now under construction and about 85 percent com-plete,
will contain 320 carloads of granite. In this
bridge will be seven granite piers, 100 feet high, 90
feet long and 20 feet wide.
BY-PRODUCTS BECOME IMPORTANT
At the Mount Airy granite quarry there is prac-tically
no loss. The sizes are all used, from the
largest cut stone to the fine grit fed to baby chicks to
help them grind the food they take into their craws.
The range is from cut and dimension stone down
through paving blocks and street curbing, flagstones,
rough ashlar, rubble, rip-rap, crushed stone, gravel
and poultry grit. This poultry grit production is de-velopinging
into one of the firm's important sources
of income. Several carloads are shipped each week,
graded into grit for turkeys, grown chickens, broil-ers,
fryers and for baby chicks. It supplies a needed
product for another growing North Carolina indus-try—
poultry raising. And, large quantities go to all
states east of Colorado.
Full utilization of the granite quarried is due to ex-tensive
study and planning to take advantage of all
sizes of stone and over a long period. Cut stone and
dimension stone form more than two-thirds of the
total sales, yet utilize only slightly more than one-fourth
of the total volume of material. By-products
are just that when attention is directed toward pro-ducing
the main items, but when periods of slack big
business occur, the by-products become the more im-portant
products of the quarry.
In the early 1890s the Cape Fear and Yadkin Val-ley
Railroad was completed from Mount Airy to
Wilmington, thus giving Mount Airy granite an out-let
to other railroads. A spur track surrounds "The
Rock" and passes the cutting and crushing houses.
This railroad, now the Atlantic and Yadkin Railway,
WINTER, 1947 THE E. S. C. QUARTERLY PAGE 7
connects at nearby points with other far-reaching
railroad lines.
Power for operation is supplied by electricity and
by a 175-horsepower engine and two 150 -horsepower
coal burning boilers. Electric cranes, compressors,
granite crushers, locomotives, granite lathes, steam
cranes, diesel shovels, granite saws, sand blast and
other equipment are in operation at the plant. In-dicative
of the value of this equipment is a new
crusher just installed which cost $35,000.
The Mount Airy granite quarry operates with a
normal force of about 400 workers. With veterans
returning for training they are gradually getting
back to that level. Many former G. I.'s are learning
the granite business. And more could be used.
At the peak of operations in 1925-1926 about 800
workers were employed. During the war period and
the later restrictions in building, the industry was
hard hit in its bigger operations, the by-products
saving the day. However, production is gradually
returning to normal, and the granite industry hopes
to get going in a big way in the next few years.
The labor at the quarry is native, efficient and sat-isfied.
Many workers have been on the payroll al-most
since they became old enough to work. In fact,
at "The Rock" may be found grandfathers, fathers
and sons working side by side.
Notable is the cleanliness and neatness observed
at the quarry. Unsuitable parts are cleaned up just
about as soon as they accumulate in the production
of the many by-products of the quarry. The keep-clean
thought is stressed and new workers soon re-
. alize that they are
to keep the place
clean and neat. It
soon becomes regu-lar
routine. That is
why the place al-ways
has the ap-pearance
of just
having been scrub-bed
and swept.
Mount Airy gran-ite
officials are
awaiting the all-clear
signal, when
the immediate needs
of veterans and
others for housing
have been met. Then
conditions are ex-pected
to be so they
can proceed with big
contracts for build-ings
and bridges, as
well as for monu-ments,
memorials,
mausoleums and
other smaller prod-ucts
of the quarry.

TALC MINING IS AN IMPORTANT
ACTIVITY IN CHEROKEE COUNTY
Talc mining is developing into an important indus-try
in Cherokee County. Two or three talc mines
have been operated in various sections of the country,
but a rich vein has been struck not far from the town
limits of Murphy and is now being worked extensive-ly.
Large quantities of talc are being mined a short dis-tance
underground by the Hitchcock Corporation,
headed by Francis Bourne, and is being processed in
a plant at the mouth of the mine.
Talcum powder, of course, is the first item thought
of when talc is mentioned—and is an important item
produced by the Cherokee County Plant. The lump
talc is ground into a fine powder and that is talcum
powder, practically the finished product, except for
the addition of perfume.
The Hitchcock Corporation also produces talc pen-cils
which are used in marking all kinds of materials,
especially iron and steel, which have to be subjected
to intense heat. Talc marks, numbers to identify
iron and steel parts, are just as plain after these ma-terials
have been subjected to intense heat as they
were before.
Two types of pencils are made by this plant. Both
are about six inches long. One is a round pencil,
about the size of the usual lead pencil, but composed
entirely of talc. The other is a flat pencil, approxi-mately
the shape of a carpenter's pencil, also com-posed
entirely of talc. The waste talc from trimming
or turning these pencils is suitable for making talcum
powder.
Talc is described as a mineral composed of mag-nesium,
silica and water, and is commonly classed as
hydrous, magnesian silicate. It is soft and has a
greasy or soapy feeling. Talc is related to soapstone,
although talc is classified as a mineral and soapstone
is of the rock family and is composed of talc, chlorite,
and impurities. Like talc, soapstone is soft and has a
greasy or oily feeling.

Washington. D. €., Balfour Pink granite from Rowan County.
Balfour Pink Most Noted of Rowan County Granites
By M. R. Dunnagan, Informational Service Representative, ESC
Nearly 200 years ago a settler moved into Rowan
County, North Carolina, and took up his abode.
Within a few years he built a house. Many other
settlers built houses. The difference is that this set-tler
built a house which is still standing, while other
houses have been built and burned or rotted away,
and the settlers rebuilt or moved on.
But this settler, Michael Braun, by name, built a
house of stone, or more accurately, of granite, and
had the foresight to place his name in the stone over
the doorway. That stone, the name and the stone
house are still there, now honored landmark, known
as the "Old Stone House" and visited as a place of
unusual interest by people of many states.
Michael Braun's house, erected in 1766, was made
of neighbohood surface stone, probably chipped and
chiseled into shape and formed into a dwelling by
slave labor Today, as 180 years have passed, it
stands intact, except in spots where the woodwork
has decayed and allowed the stone to shift.
Near the "Old Stone House," the Balfour Pink,
the Carolina Pink, the Shuping and the Dunn Moun-tain
quarries are owned by The Harris Granite Quar-ries
Co., and, since Michael Braun's day, have fur-nished
great quantities of the highest test, most in-destructable
granite to be found on earth for erec-tion
of millions of dollars worth of public buildings,
bridges, mausoleums, monuments, memorials, and in
building highways and streets in many states, and
in foreign countries.
Note—Material used in this article was furnished largely by John E. Ram-sey,
vice-president and general manager of the Harris Granite Quarries Co.,
Salisbury, N. C.
"Old Stone House" four miles out of Salisbury. Erected in 1776
by Micnael Braun of Roivan County granite, near one of the
present famous quarries. Still standing and almost intact, it
is one of the shoto places of the State.
BALFOUR PINK—"GRANITE ETERNAL"
Balfour Pink—the best known of the Rowan
County granites, by U. S. Government tests, is one
of the hardest, toughest and most durable granites
known. It takes a very high polish. It is truly a
"Granite Eternal." The Federal Trade Commission,
desiring "truth" in advertising, questioned the trade
mark "Granite Eternal" under which it was sold.
John Ernest Ramsay, vice-president and general
manager of The Harris Granite Quarries Co., who
has been in charge of quarrying and testing Balfour
Pink Granite, replied as follows : "We use the word
'Eternal' in the same sense as it is found in the Holy
Scripture when it speaks of "The Eternal Hills."
The hills are in many instances based on granite,
their surfaces change, but Balfour Pink Granite,
cooled and formed before the existence of man has
not shown but slight erosion since its formation, and
it is more permanent than 'The Eternal Hills'." The
trade mark "Granite Eternal" continues.
Official tests show that Balfour Pink Granite is
composed of: Silica (quartz) 76.06, Alumina 14.10,
Potash 6.00, Soda 2.01, Iron Oxide 1.20, and traces
of lime manganese and Titanium Oxide, Sulphuric
and Phosphoric Anhydride. Other qualities: Loss
on ignition .12, water absorption .772, crushing
strength 34,860, percent of wear 2.0, hardness 18.7.
Microscopic examination reveals the complete inter-locking
and entwining of its crystals, showing its
dense and compact and homogeneous structure.
The above chemical and physical tests, setting
forth low absorption and dense structure, prove Bal-four
Pink Granite to be eminently suitable for polish-ed,
hammered, honed, stippled and quarry face fin-ishes,
and for use in permanent structures, monu-ments,
mausoleums, public buildings, bridges and
highway construction. Liner blocks for tubular
mills, pebbles for pulverizing and grinding, Durax
and paving blocks for heavy traffic and steep grades
in streets are manufactured from the high test and
durable granite and are receiving a ready sale.

a slight purplish tint. When carved or lettered, it
has a decided contrast of color, and is extensively
used for memorials and public buildings.
Carolina Pink Granite, when polished is slightly
darker, having a creamy peach-glow tint. It is not
quite as hard as Balfour Pink Granite, and is manu-factured
at a slightly lower cost. The Harris Gran-ite
Quarries Co. also owns Dunn Mountain, Shuping,
Powlas Mountain, and Rowan quarries which are
not in operation—owing to labor shortages.

Ruckstuhl was taken to the small opening of the Bal-four
Pink Granite Quarry, by Mr. Ramsay, and upon
examination of the granite, was so highly pleased that
he said: "This is one of the most beautiful granites
I have ever seen. If I were you, I would soon be in
the granite business." Mr. Ramsay later became as-sociated
with Mr. George R. Collins who came to
Salisbury from Asheville in the operation of the Bal-four
Quarry. Subsequently, after several years, Mr.
Ramsay became vice-president and general manager
of The Harris Granite Quarries Co., largely owned
and organized by the late Charles J. Harris of Dills-boro,
N. C.
IMPORTANT LOCAL INDUSTRY
The quarries are all open-face pits. The Balfour
Pink quarry now covers more than five acres and in
places is more than one hundred feet deep. All of the
quarries are within a radius of six miles of Salisbury,
N. C. The Cutting Plant is within the city limits of
Salisbury, on the Southern Railway line to Atlanta.
The offices of the company are in the Wallace Build-ing.
Representatives of the companies have travelled
extensively presenting the beauty and qualities of
Rowan County Granites. Many contracts have been
secured, and thousands of dollars have been brought
into the county from the sale of one of nature's de-posits.
During World War II, practically all granite
products were declared to be non-essential, labor
from the quarries left for other industries, and have
not all returned, and the companies are greatly be-hind
in making deliveries. During the War Period,
liners, grinding and pulverizing stone could not be
obtained from over seas. The Harris Granite Quar-ries
Co. erected mills, produced pebbles of various
sizes for grinding and pulverizing, and lines blocks
for lining tubular mills, thereby assisting in the War
effort.
The Harris Granite Quarries Co. has a large plant
located in South Salisbury, equipped with highpow-ered
electric cranes, air compressors, granite saws,
polishers, carbo saws, surfacers, sandblast room,

International Demand for Cherokee County Marble
James Chadwick, Assistant Secretary Columbia Marble Company, Marble, N. C.
Marble is one of Cherokee County's valuable raw
materials. The main marble outcroppings are evi-dent
at Hewitts in Swain County near the Nantahala
River and extend almost due south into Cherokee
County approximately twenty-five miles to Valley
River. In the center of this zone, near Marble, the
choice blue and grey marble is quarried. A smaller
marble belt begins at the head of Peachtree Creek
and runs parallel to the above marble nearly ten
miles to Little Brasstown Creek.
Perhaps the first marble quarried in Cherokee
County for a commercial purpose was by the Notla
Marble and Talc Company in 1900. Their quarry
was located five miles southwest of Murphy and was
named Kinsey Quarry. The marble quarried was
good but the only sales made were for flux.
In 1902, the Regal Marble Company was opened
by Captain Brady at Regal, three and one-half miles
northeast of Murphy with B. M. Harben as general
manager. The company had a personnel of thirty
men and this marked the real beginning of the marble
industry as a manufacturing enterprise. The first
operations of this company was quarrying the marble
and sawing it into slabs for shipment.
The next owner of the Regal company was the
Casparis Marble Company. This company began the
fabrication of the marble into monuments.
CHEROKEE COUNTY COURTHOUSE
Raymond Harris was the next manager. It was
under his direction that the stone for the Murphy
courthouse was made. The courthouse, a two story
structure approximately three hundred by two hun-dred
fifty feet, was built in 1926 and 1927 out of
Regal Blue marble. It contains about twenty-five
offices and the courtroom. Four massive blue marble

The entrance to the
courthouse leads in-to
a rotunda fifty
feet high. From the
rotunda, hallways
lead to the various
offices.
During the Regal
operations, three
quarries were open-ed.
They ranged in
depth from one hun-dred
to one hundred
thirty-five feet and
all yielded blue mar-ble.
Business became
dull and J. A. Martin
bought the company
and moved to Mar-ble,
ten miles north-east
of Murphy. His operations were chiefly crush-ed
stone and its products.
The company was then acquired by Hinds and
Adams of New York. They kept it only a short time
and the Columbia Marble Company of which B. F.
Coggins was president purchased it.
In 1931, the company moved one mile east of
Marble and located on the Southern Railway. A
steel finishing plant one hundred fifty feet by two
hundred sixty feet was built. Modern machinery
was installed and two overhead cranes were erected
to facilitate operations. When operations began,
there was approximately forty-five thousand square
feet in the quarry area.
MANUFACTURING PROCESSES
The company uses the following process to manu-facture
a monument or slabs for buildings. Four
gang saws divide the blocks into slabs and these are
sent to two diamond saws for further division. Three
rubbing beds are operated to put a smooth finish on
the marble. At this point, the marble begins to take
the shape of monuments or slabs of buildings. After
the smoothing process, it is sent to the cutters
benches where it is cut in various designs by pneu-matic
air hammers and carborundum saws. Two
polishing machines are used to put the silk like gloss
on the marble and to bring out its beautiful texture.
Expert designers then place the designs and letters
WINTER, 1947 THE E. S. C. QUARTERLY PAGE 1 1
on the marble with tools and sandblast equipment.
The memorial is then finished and sent to the ship-ping
department to be crated and shipped.
Columbia Marble Company contributed a large
part to the defense program by selling the steel shed
and two overhead cranes to Hinderliter Tool Com-pany
of Tulsa, Oklahoma in the early part of the war.
They dismantled the building and moved it to Tulsa
where it was reconstructed as a part of a defense
plant. After the steel building was removed, the
company built another finishing plant at the same
location.
In 1945, T. A. McGahey of Columbus, Mississippi
purchased the Columbia Marble Company. At the
present time, he is President-Treasurer. The other
company officials are : T. A. McGahey, Jr., Vice-Presi-dent-
Secretary ; James Chadwick, Assistant-Secre-tary
; and Edward Plesko, General Manager.
The quarries of the Columbia Marble Company
produce two types of marble. They are Regal Blue
and Sterling Grey. These marbles are crystalline in
texture and their main constituent is limestone. They
take a high polish and the absorption of water is low.
The stone is durable and suitable for both monu-mental
and building material. Although practically
all the marble quarried is manufactured into a finish-ed
product, there is some waste or scrap. This is
sold locally to build buildings or sent to paint com-panies
or iron mills for fluxing purposes. Alabama,
Vermont, and Tennessee marble are also bought and
sold by the Columbia Marble Company.
The sales of the Columbia Marble Company have
become almost universal. The marble is sold in all
states, Canada, Hawaii, and in the islands south of
Florida. Sales have consisted of monuments, bank
fronts, mausoleums, soda founts, baptismal bowls,
grave vaults, and interior and exterior marble for
buildings.
MARBLE IN NOTABLE BUILDINGS

Philip Liberman Synagogue in Miami, Florida;
U. S. Post Office and Courthouse in Statesville, North
Carolina ; Saint Mary's Roman Catholic Church in
Saint Petersburg, Florida ; and The Schwob Company
in Columbus, Georgia.
The outstanding monument processed was the
memorial to William Jennings Bryan. This monu-ment
had approximately five hundred cubic feet of
Tennessee marble in it and required about thirty days
to carve. A five-ton crane would not lift one piece of
this monument because of its weight.
The Columbia Marble Company is operating six
days a week and furnishing gainful employment to
about forty-five people. It's officials are looking to-ward
the future with optimism in anticipation of do-ing
a larger and better business in the marble in-dustry.
In December, 1946, it was found by UCC officials
that 62 claimants for unemployment benefits in the
regular UCC program had received benefits in prior
months to which they were not entitled, aggregating
$2,362.00. In 16 cases involving evidence of fraud,
the UCC has or will prosecute the recipients. In the
other cases demand for repayment of the amount in-volved
has been made. Those not refunding the
amount will have it charged against their accounts
and deducted from any benefits they may be due to
receive when and if they file claims for benefits
later.

Behind Scene In Locating Stone for Duke University
By Brent S. Drane, Engineer, Construction Division United States Civilian Production Board
Several months ago a chance inquiry by a friend
of mine started me on the task of recapturing the
record of the chain of events which located the stone
from which the new Duke University was built. It
was surprising how disjointed and scattered I found
the links in the record, and, most of all, how inade-quate
was the record of the matter in the files of the
Geological Survey. Now that I have the record in
hand, it seems to me that I ought to take pains to see
that the full account gets into the Survey's public rec-ords
; because it reflects upon the Survey credit in
keeping with its highest traditions.
I am therefore addressing this letter to you for
that purpose. I take the privilege of writing it as a
friendly personal narrative rather than in crabbed,
scientific report style ; but it is, I believe, entirely ac-curate
for all that.
For the background picture I am using John Wilbur
Jenkins' account in his "James B. Duke, Master
Builder." In this matter he gives a trained journal-ist's
straighforward account of events then quite re-cent,
involving people whom he knew and understood.
Mr. Jenkins describes the 1924 establishment of
the Duke Foundation, which transformed Trinity
College into Duke University; Mr. Duke's close per-sonal
concern with every detail of the evolution; his
choice of the architect whose Princeton buildings he
liked. He tells of the apparent impasse when prices
of adjacent land needed for expansion of the old
Trinity Campus climbed to levels which Mr. Duke de-clined
to pay ; of the proposal to buy the large unde-veloped
woodland area which the new Duke Univer-sity
now occupies, and of Mr. Duke's pessimistic dis-belief
that the purchase could be negotiated secretly
enough to prevent another hold-up ; of how Professor
Flowers, the University Treasurer, had to beg to be
NOTE: This article is in the form of a letter from Brent
S. Drane, Washington, D. C, who, at the time of the inci-dents
described in it, was State Director of the old North
Carolina Geological and Economic Survey, to Dr. Jasper L.
Stuekey, then, and now, State Geologist, with the State De-partment
of Conservation and Development, which succeed-ed
the Geological and Economic Survey.
Mr. Drane, formerly of Charlotte, was for some years an
engineer with the Water Resources Division of the National
Planning Board in Washington. Subsequently he served in
the Water Division of War Utilities of the War Production
Board. He is now with the Construction Division of the
Civilian Production Board. He first wrote the letter to
Louis Graves, Chapel Hill publisher. A copy happened to
fall into the hands of our M. R. Dunnagan, who, because of
its historic value, asked Mr. Drane's permission to use it.
Realizing the importance of the information to posterity,
Mr. Drane embraced it in a second letter to Dr. Stuekey, so
it could become a part of the public records of the Mineral
Resources Unit of the Department of Conservation and De-velopment.
Since the original letter was addressed to Mr. Graves, he
was given opportunity to make public the letter to Dr.
Stuekey, which he published in his Chapel Hill Weekly of
January 31, 1947. Mr. Dunnagan was also given permission
to use it in this issue devoted largely to granite, marble and
other stone products in North Carolina.—Henry E. Kendall.
allowed to see what he could do, and of his success
that astonished and delighted Mr. Duke.
He tells how Mr. Duke had test panels built of the
various building stones proposed by his advisers so
that he could see for himself just what each looked
like ; and how, when the general choice fell on a stone
from a distant State which would have cost a fortune
to transport, he called for backing up and starting
all over again with more study of what lay nearer at
hand.
MR. DUKE CALLS FOR STONE
So much for the stage setting. Mr. Duke had told
his employees and Duke faculty collaborators to get
out and find him a new quarry. There is no doubt in
the world but that under those circumstances a new
quarry was going to be found, and a good one; for
there was a great deal of pressure behind the old
gentleman's mild expression of his desires, as I had
HURONIAN SLATE, USED IN DUKE
UNIVERSITY BUILDINGS, DEFINED
By Dr. Jasper L. Stuckey, State Geologist
State Department of Conservation and Development
The Huronian Slate Belt, from which the stone for the
buildings on the west campus of Duke University was ob-tained,
has been of interest for more than one hundred years.
It was first described by Denison Olmstead in 18 25 in a print-ed
report entitled "Report on the Geology of North Carolina
Conducted Under the Board of Agriculture," published by
J. Gale and Son, Winston-Salem, North Carolina. In this
report, Olmstead described the "Great Slate Formation" in
Person, Orange, Chatham, Montgomery and other counties.
The slate belt was further described by Ebenezer Emmons
in his "Geology of the Midland Counties of North Carolina,"
published in 18 56. W. C. Kerr, in his "Geology of North
Carolina," published in 1875, added the name "Huronian"
in his description of the slates. Olmstead, Emmons, and
Kerr all considered the rocks of the slate belt to be normal
sediments which had been changed to slate by metamorphism.
G. H. Williams, Professor of Geology in the Johns Hop-kins
University, studied a small area of the slate belt in
Chatham County and published a paper on his work in the
Journal of Geology, Vol. 2, 1894. He described the rocks as
volcanic flows and breccias with finer tuff deposits, all
metamorphosed into slates by dynamic agencies.
The Carolina Slate Belt, as it is known today, embraces
a belt of country which varies in width from eight to fifty
miles and extends in a general northeast-southwesterly di-rection
across the State. Its western boundary is marked
by a line a few miles east of Greensboro, Lexington, and
Charlotte. Its eastern boundary is marked by a line a few
miles west of Durham, Sanford, and Wadesboro.
The rocks of the area, because of the complex character
and well defined cleavage, have been called "slates"; but
the name is misleading and confusing. They consist of vol-canic-
sedimentary formations made up of slates and tuffs
with which are long interbedded bands and lenses of vol-canic
breccia, flows and ash. There are two distinct types
of tuffs, breccias and flows: one is acid and the other a more
basic phase. The acid phase consists of fine and coarse
tuft's, and breccias chiefly of a rhyolitic and dacitic character,
with flows of rhyolite and dacite. In the basic phase the
breccia and flow types are more common than the fine and
coarse tuffs, but the latter are usually present in at least
small amounts. Both phases are more or less stained and
colored by weathering. The acid phase contains gray, red-dish,
and brown colors while much of the basic phase is
greenish in color due to the formation of epidote in it.

observed in an interesting experience I had once had
with him. The only question now was how to find it
in an atmosphere so over-charged with suspicious
fearfulness and secrecy, a hang-over from the land-price
impasse which had just been escaped.
Your and my connection with the business began,
as I connect up the dates, early in January, 1925,
when I was the new Director of the State Geological
and Economic Survey and you were the new State
Duke University Aik View—Duke University's massive build-ings.
West Campus, erected on a plateau nearly a mile long
and one-third of a mile wide and located about a mile west of
the City of Durham, were constructed of stone taken from a
quarry about 15 miles away, located a few miles west of Hills-boro,
near the Eno River, close to the Southern Railway tracks
and a short distance from the State Highway between Hillsboro
and Efland.
The stone is classified as Huronian slate, similar to a stone
found near Lake Huron. In the quarry, owned by Duke Univer-sity,
were found all of the seven primary colors and seventeen
different shades of these colors, making it particularly suitable
and beautiful for development of a great university plant. The
quarry is said to contain enough desirable stone to erect an-other
group of buildings as large as those which make up the
main part of Duke University.

Geologist. I was on an evening train for Greensboro,
just past Durham, when I was joined by a Charlotte
friend, member of the construction company which
was doing Mr. Duke's experimental work in Durham.
After a little he got me to go with him to his seat to
look at some stone specimens he had in his bag.
With extravagant caution against being seen or over-heard,
he showed me several pieces of lustrous black
hornblende gneiss, and asked me if I knew where it
could be found in quantity. I thought that I did and
proposed to verify my ideas and write to him. He
knew that I knew enough of Mr. Duke's plans and of
his own connection with the sample panels of mason-ry
on Trinity Campus to make his present interest
no mystery to me. Upon undertaking to keep our
talk confidential, he told me in some detail of the
Princeton buildings that Mr. Duke had picked as his
prototype. In conclusion I advised him to consult
with you, the State Geologist.
DR. STUCKEY IS CONSULTED
Promptly after this the Business Manager of the
new Duke University came into the picture, a Pro-fessor
of English whose keenness in practical matters
PAGE 14 THE E. S. C. QUARTERLY WINTER, 1947
had brought him to the front in Trinity College's
business management. He called at the Geological
Survey offices in Raleigh and was promptly turned
over to you. Happily, you were extraordinarily well
prepared for just such a consultation. Back in 1920
at Dr. Pratt's suggestion you had made a collection
of more than a hundred specimens representing the
range of building stones found in North Carolina,
and the collection was still intact at the Survey's old
quarters at Chapel Hill. After a general discussion
with him, you made an appointment to meet him
later in Chapel Hill to show him the specimens and
give him more information based upon them.
Very shortly after that you had a visit in Raleigh
from my contractor friend. He told you of our
earlier discussion on the train, showed you what
doubtless were the same specimens of hornblende
gneiss he had shown me, and gave you to understand
that they represented a type of stone sought in con-nection
with the Duke University building program.
Your knowledge of the occurrence of this stone in
western North Carolina was of course much more
definite than mine had been ; and you gave him what
information you could about its occurences nearest to
Durham.
Several days later you got a letter from him and a
small package containing several other specimens of
stone ; the letter stated that these, rather than those
he had shown you on his visit were of the type par-ticularly
wanted for the Duke buildings. You brought
the new specimens to me for examination, and we
discussed them in some detail. We both recognized
the mailed-in samples as similar to material used for
flagstone in Chapel Hill ; and we recalled that it was
quarried somewhere near Hillsboro. As a result of
our discussion we agreed that you ought to learn all
you could about the Hillsboro sources before meeting
the Duke Business Manager, Professor Brown, at
Chapel Hill.
LOUIS GRAVES' FLAGSTONES
Here is where some of my close personal friends
become active helpers. I recalled particularly the
flagstones Louis Graves had at his home in Chapel
Duke Hospital—Showing entrances to lobby and clinic.
Hill ; I had noticed them and asked him about them.
I consequently wrote from the Survey Office in Ral-eigh
on January 15, 1925, to my friend Cheshire
Webb, an active and public-spirited business man in
Hillsboro.
''I am very much interested to know where the old
stone flagging used around Hillsboro came from. I
recall that Louie Graves sent to Hillsboro for flags
to put in his yard. Won't you try to get all the dope
you can to me from the old residenters?"
Mr. Webb replied at once that he knew the quarry
from which the flagstone had come; and that he
would be glad to show it to me or to anyone I might
send to him. That one was, of course, yourself. On
the morning of the day set for your afternoon ap-pointment
with the Duke Business Manager, Mr.
Brown, in Chapel Hill, you went first to Hillsboro and
got in touch with Mr. Webb. He took you out to the
old quarry, and there you collected a number of speci-mens.
That afternoon after reviewing with Mr. Brown
your collection in the old Survey Offices in Chapel
Hill, you showed him your Hillsboro specimens. He
professed to be somewhat critical of them, but he
could not entirely conceal an eager interest; and he
asked permission to take several of the specimens
with him. Bright and early the next morning he wag
in Hillsboro, calling on Mr. Webb.
That ends the story of the finding; but Mr. Webb's
concern in the matter, which was of major import-ance,
continued. At Mr. Brown's request he obtained
a purchase-option on the quarry-farm. I have a letter
which Mr. Brown wrote him dated "24 January,"
cautioning him ; "Please be sure to have the man's
wife sign it ; otherwise it is not of much value ... As
soon as the option is signed I shall be grateful if you
will notify me that we may make an examination of
the quarry."
CHESHIRE WEBB HANDLES DEAL
Two options are recorded in the Hillsboro Court
House, both signed January 31, 1925, and filed for
registration February 3. One was a 60-day option
on the right to acquire for $595 in cash, the right to
mine and remove the rock and stone from the land,
except an 8-acre tract immediately surrounding the
dwelling house. The other was an option on the right
to buy the 72-acre farm outright for $4,000. I have
a letter which the University Treasurer, Professor
Flowers, wrote to Mr. Webb on March 26, 1925. The
options were about to expire, and Mr. Webb had evi-dently
told him that if the University did not want
the property he intended to buy it. The letter states
that Professor Flowers wishes "to confirm the state-ment
made on the telephone last evening" ; that if
Mr. Webb will relinquish the options to him he will
undertake to endorse them back to him if they are
not exercised before the date of their expiration ; and
if the options are exercised and the stone then found
not suitable for the University's purpose, he will give
Mr. Webb the opportunity to acquire the rights under
the options at the same price they cost. "I appreciate
WINTER, 1947 THE E. S. C. QUARTERLY PAGE 15
very highly the help you have rendered us," he said.
I have also a letter from Mr. Brown to Mr. Webb
rather elaborately stating his appreciation for his
"fine and unselfish spirit in being so willing to do
such a service for the institution." On March 31,
1925, the land was bought under the purchase option
by a Durham real estate agent acting for Duke Uni-versity,
and he gave deed to Duke University on
April 24 following.
Your records show that you made five subsequent
trips to the property with Mr. Brown. In the course
of the investigation the latter got the State Highway
Commission to make some tests of the Hillsboro
stone, with the arrangement that you should write
the interpretation of the tests. Later on, Professor
Flowers arranged for tests and a report by the United
States Bureau of Standards at Washington, and he
sent you a copy of that report. It pleased you to find
that you had been more conservative in your inter-pretation
of the Highway Commission tests than was
the interpretation of its own tests by the Bureau of
Standards.
Its soundness having been proven by tests, the
great value of that particular body of stone lay in its
nearness to the Hillsboro-Durham railroad. It cost
relatively little to build a short spur-track into the
quarry, so that quarried stone coud be mechanically
loaded at very low cost directly into a railroad car
and cheaply transported to the very site of the build-ing
for which it was destined. The perfect combina-tion
of high quality, easy accessibility, and low-cost
transportation—to say nothing of its low purchase-cost,
all made that particular quarry the kind of a
find that delights a construction man's heart ; and at
heart Mr. Duke was a construction man. This was
exactly what he had told his people to get out and
find.
GEOLOGICAL SURVEY HELP RECORDED
But the way in which it was found has, I think not
heretofore been recorded so as to give proper credit
to the Geological Survey. The well-established tradi-tion
that a business-like Professor did the finding
has exalted a middle-man. to the complete obscura-tion
of how the desired stone actually came to be
found in this particular outcrop. It was inconspicu-ous,
little known, not actively worked as a quarry, and
the chance was infinitesimal that it ever could have
been thought of as a site for a larger quarrying oper-ation.
But the Duke University Business Manager
had more luck than anyone could have had any right
to expect when he followed the logical course and
consulted the State Geologist. That State Official
happened to have been particularly prepared for this
very job by his eminent predecessor, Dr. Joseph Hyde
Pratt. But beyond and entirely apart from that,
"The long arm of coincidence" must be given a large
share of the credit ; in the circumstance that I hap-pened
at the time to be Director of the State Geolog-ical
and Economic Survey, that Louis Graves and his
flagstones in Chapel Hill were my good friends, and
that Cheshire Webb in Hillsboro was a good and loyal
ally of mine, ready and zealous to help bring to a
handsome conclusion a matter of the old Geological
Survey's business in which I had asked his friendly
help.
UNEMPLOYMENT DECREASES:
AVERAGE WEEKLY WAGES
SHOW AN INCREASE
Industry in North Carolina is making a strong
effort, and with a marked degree of success, to over-come
the natural and man-made handicaps that grew
out of the World War II crisis, as indicated by the
increase of workers in covered employment.
In a compilation prepared by S. F. Campbell, of
the Bureau of Research and Statistics, it is revealed
that covered employment in North Carolina in the
second quarter of 1946 was only 8.7 percent below
the highest level reached during the all-time high
period in the early war year of 1942, when 591,391
workers were in covered employment.
During 1942 war camp construction was at its
height and Selective Service withdrawals had not
reached their peak. In one quarter of that year
covered employment exceeded 600,000. Selective
Service withdrawals, demand for workers in war
industries in other states and halting construction
work generally reduced the covered labor force in
the State to 509,352 workers in July, 1945, the
lowest point reached. From that date employment
began to increase, despite the lay-off of about 70,000
war workers in August, 1945 ; by September 527,527
were employed and by December 539,180 covered
workers were employed.
Also, during this period, wages were showing a
steady increase, an increase of 30.9 percent from
$23.75 average weekly wage in 1942 to $31.10 in
1945. From an average weekly wage of $17.44 in
1940, the increase was 78.3 percent by 1945.
By comparing the wage increases in North Caro-lina
with those of the nation, Mr. Campbell points
out that the State still has nothing to boast about.
Whereas, he finds, the average weekly wage of wage
earners or production workers is still below the
national level, the average salaries of corporate
officials and administrative personnel are lower still
when compared with the national level.
Indications are that a small drop may be seen in
average weekly wages of covered workers in 1946,
as compared with 1945, due to the discontinuance of
war-time shipbuilding, ordnance and electrical ap-paratus.
Skilled workers in these industries are not
being replaced by activities which require labor of
comparable skill and earning capacity.
Unemployed workers in North Carolina had been
paid through March, 1947, a total of $32,059,842.20
from January 1938, when benefits were first paid
under the Employment Security program. Liable
employers had paid $147,227,679.30 in contributions
into the fund, which, deposit in the U. S. Treasury,
had earned $9,810,204.10 in interest. This gives
total receipts of $157,037,883.40, and a balance on
March 31 of $124,979,041.20.

State's Limitless Store of Non-Metallic Minerals
By T. G. Murdock, Assistant State Geologist North Carolina Department of Conservation and Development
GENERAL FEATURES OF THE GEOLOGY
It would be expected that the first state to have
sponsored geologic research and to have had a formal-ly
organized geological survey since 1852 would be
an important producer of a wide variety of rock
products. Although a generous nature has endowed
North Carolina with over 300 different minerals and
many kinds of rocks, the deposits of metals and min-eral
fuels are small in comparison with other states.
This situation has led to the development of the in-dustrial
rocks and minerals—the less spectacular
non-metallics.
The Mineral Resources Division of the North Caro-lina
Department of Conservation and Development is
actively engaged in a broad program of geologic re-search
under the direction of Dr. Jasper L. Stuckey,
State Geologist. Since 1936 the total value of the
State's mineral production has more than doubled,
and in 1944 established an all-time record.
North Carolina has a total length from east to west
of 503 miles and lies across three geological prov-inces
: The Coastal Plain, Piedmont Plateau, and the
Appalachian Mountains. The rocks and minerals
and their geologic relations in each province are dis-tinctive.
Stratigraphically the rock formations
range from ancient pre-Cambrian crystallines of the
Mountain Province to coastal and estuarine sands
and gravels of Quaternary age, constituting the most
easterly formations. Thus the State's mineral re-sources
have been formed by various processes and
at many different times, in rocks ranging in age from
half a billion years to a few thousand. The structure
of the rock units in some parts of the State is simple
and in others very complex.
The Coastal Plain extends from the Atlantic Ocean
on the east to the Piedmont Plateau on the west. Its
area is about two-fifths of that of the State, exceed-ing
21,000 square miles and embracing wholly, or in
part, 42 of the 100 counties. It is underlain by rela-tively
young, loosely consolidated sediments that dip
gently towards the ocean. The most important
known mineral resources of the Coastal Plain are ce-ment
materials, clay, greensand, phosphate rock,
sand and gravel, shell limestone, shell marl, and peat.
The Tuscaloosa formation is the earliest of the
Cretaceous sediments in North Carolina and rests on
the eroded edges of the basement rocks. This forma-

gray or greenish-gray in color, though locally stained
by iron. The Black Creek sands and clays and the
Pee Dee sands are representative formations of the
upper Cretaceous. An ideal section of the overlying
Tertiary sediments shows that the Eocene is repre-sented
by the Castle Hayne marls and shell rock ; the
Miocene by the Trent, St. Mary's, Duplin, and York-town
formations; and, the Pliocene by the Wacca-maw
and so-called "Lafayette."
"CAROLINA SLATE BELT"
The central hill country, known as the Piedmont
Plateau, attains a greater width in North Carolina
than in the states to the north, and is also far more
rugged. The western margin of this Plateau has an
altitude of 1200-1500 feet above sea level. At places
precipitious spurs of the Blue Ridge Mountains pro-ject
eastward and southeastward across the Pied-mont
section in irregular, straggling ranges. The
area of this region is about 22,000 square miles ; its
altitude descends gradually from 1500 to about 300
feet, with an average close to 1000 feet.
The Piedmont Plateau is largely underlain by very
old, highly deformed crystalline rocks with smaller
amounts of well consolidated, gently folding sedi-ments.
Mesozoic sediments, mainly shales and sand-stones,
are represented by two areas of Triassic
strata: The Dan River area of Stokes and Rocking-ham
counties, and the larger Deep River area, com-prising
the belt of central and south central counties
from Granville to Montgomery. Algonkian rocks
cover a large portion of the middle and lower Pied-mont
Plateau—the area known as the "Carolina
Slate Belt"—and consist of a great series of schistose
volcanics and slates. This series is composed of ash
and tuff of rhyolitic and andesitic compositition,
flows of rhyolite and andesite, and beds of shale, all
of which have been metamorphosed into schistose
and slate-like rocks.
"CAROLINA IGNEOUS BELT"
The "Carolina Igneous Belt," composed principally
of Carboniferous granite, occupies a nearly central
position in the Piedmont Plateau and extends in a
northeast-southwest direction from South Carolina
on the south nearly to Virginia on the north. The
width is 15-50 miles and it is traversed for most of its
length by the main line of the Southern Railway. In
addition to granite, this area is composed of diorite
and there are numerous dikes of diabase and other
basic igneous rocks which penetrate the older rock.
The rocks of the western Piedmont are mainly of
the pre-Cambrian Carolina gneiss formation, whose
original nature is in doubt but it probably consisted
of igneous and sedimentary rocks. The Carolina
gneiss consists of a great series of interbedded
gneisses and schists, chiefly composed of quartz,

varying amounts of acid feldspar and either musco-vite
or biotite or both. At times either garnet or
kyanite may be dominant minerals in the gneiss or
schist. The rocks are light or dark gray, and have
a fine grain, marked schistosity and, except for the
larger crystals of kyanite and garnet, an even tex-ture.
The Cambrian metamorphosed sediments form
scattered belts and irregular areas in the upper Pied-mont
Plateau and Mountain sections of the State. In
their present condition these formations are largely
schist, slate, and quartzite. The most important
known industrial mineral deposits of the Piedmont
Plateau are barite, clay and shale, granite and gneiss,
kyanite, kaolin, limestone, marble, mica, monazite,
pyrophyllite, quartz, sandstone, sillimanite, slate,
soapstone, spodumene, and trap rock.
The Mountain region of North Carolina includes
the Blue Ridge, the Great Smoky Mountains, and the
country between, which is occupied by numerous ir-regular
ranges, often separated by narrow valleys
and deep gorges. The average altitude of this re-gion
is about 2700 feet above sea level but the sum-mits
of many ridges exceed 5000 feet, and a consid-erable
number of peaks tower above 6000 feet. Over
the larger part of this region are to be found the
older crystalline rocks, largely gneisses and granites,
which are continuous with those of the western part
of the Piedmont Plateau, and, like these, are con-sidered
of pre-Cambrian age. These rocks are often
greatly folded and faulted and extreme metamor-phism
has frequently obscured or completely obliter-ated
all traces of their original character. On the
western and eastern borders of this mountain region,
approximately along the line of the Blue Ridge and
Great Smokies, are two narrow belts of younger
rocks consisting of limestones, sandstones, shales,
and conglomerates, and their metamorphic equiva-lents,
crystalline limestones, slates, and quartzites.
ANCIENT ROCK FORMATIONS
The Mountain and Piedmont regions of North Car-olina
are but a portion of the great belt of crystalline
rocks that is coextensive with the Appalachian Moun-tain
system. On account of their complex structure,
and highly crystalline character, these rocks are
generally considered to be of Archaen age. The prin-cipal
constituent of this system is banded gneiss,
which includes many masses of granitic and other
distinctly igneous rocks, and which often, through
higher development of lamination, passes into mica
schists and amphibole-schists.
The gneisses have been usually considered, in part,
sedimentary rocks that have lost most of their orig-inal
characteristics in the great earth movements and
other metamorphosing agencies to which they have
been subjected. Some of them are undoubtedly gran-ites,
diorites, and other igneous rocks that have been
sheared or squeezed by the same agencies, and tran-sitions
from the massive to the laminated forms are
common.
