MINE INSPECTOR FOR THE TERRITORY OF NEW MEXICO. SILVER CITY, N. MEX., August 11, 1900. SIR: In compliance with section 3 of an act of Congress approved March 3, 1891, entitled "An act for the protection of the lives of miners in the Territories," I herewith beg leave to submit the eighth annual report of this office, covering the fiscal year ended June 30, 1900. JOHN W. FLEMING, United States Mine Inspector for the Territory of New Mexico. Hon. MIGUEL A. OTERO, Governor of the Territory of New Mexico, Santa Fe, N. Mex. BERNALILLO COUNTY. W. A. CLARK COAL MINE. [W. L. Bretherton, agent.] This mine is located about 5 miles west of the town of Gallup, Bernalillo County, N. Mex. Owned and operated by W. A. Clark. Kind of coal, lignite; thickness of vein, 5 to 7 feet; total output for fiscal year ending June 30, 1900, 90,050 tons; estimated value of output, $124,269; length of slope, 3,000 feet; value of improvements this year, $17,000; average number of men employed outside, 35; average number of boys employed outside, 3; average number of men employed inside, 190; average number of boys employed inside, 10; where coal is marketed, New Mexico, Arizona, and California; number of days mine worked, 290; number of tons of coal used at mine, 1,900. This mine also produced 6,250 tons of fire clay, which is of an excellent quality, and is shipped to Jerome, Ariz., where it is used for furnace lining in the copper furnaces at that place. This mine is situated on a spur connecting with the Santa Fe Pacific Railway, about 4 miles west of Gallup station. Is operated by a slope 3,000 feet in length and has a capacity of 1,000 tons per day. This property consists of 1,280 acres of coal land, which carries several seams of coal, only one seam being worked at present. The workings are dry and free from gas or fire damp. The coal is a soft lignite, good for steam and domestic purposes. This mine shows an increase in production of 43,064 tons, an increase of 135 men employed, an increase of 20 days more worked, and 1,500 feet increase in length of slope over that of the fiscal year ending June 30, 1899. This mine is excellently equipped with first-class electrical appliances and with modern mining machinery. On my last visit to the mine it was ventilated by air shafts from the vein of coal to the surface, but a new air shaft has been sunk on the mine and connected with the underground workings and a new fan has been ordered. Just as soon as the fan arrives at the mine it will be erected, as I was informed by the agent on June 19, the date of my last visit to this mine. I was informed that the fan which was ordered would have a capacity of 100,000 cubic feet per minute. When this fan is erected it will greatly improve the ventilation throughout the workings of the mine. RECORD OF INSPECTION. September 26, 1899.-On this date I was engaged in inspecting the mine known as the W. A. Clark mine. I measured 6,980 cubic feet of air entering the mine per minute and measured 7,140 cubic feet of air returning per minute. I found the workings of the mine well ventilated and in good condition. November 9, 1899.-On this date I again inspected the mine known as the W. A. Clark mine. I measured 10,960 cubic feet of air entering the mine per minute and measured 12,310 cubic feet of air returning per minute. I found the workings of the mine well ventilated and found the working places well timbered and in good condition. January 8, 1900.-On this day I again inspected the mine known as the W. A. Clark mine. I measured 6,600 cubic feet of air entering the mine per minute and measured 6,820 cubic feet of air returning per minute. I then inspected the workings of the mine and found the rooms on the first east entry driven too far in advance of the air and ordered crosscuts driven between the rooms. Otherwise I found the mine in good condition. March 15, 1900.-On this day I again inspected the mine known as the W. A. Clark mine. I measured 11,880 cubic feet of air entering the mine per minute and measured 12,620 cubic feet of air returning per minute. I then inspected the underground workings of the mine and found some of the rooms driven too far without having crosscuts driven between them. The underground workings of this mine are quite extensive, and I ordered Mr. Bretherton to erect a fan on the mine. April 17, 1900.-On this day I again inspected the mine known as the W. A. Clark mine. I measured 6,780 cubic feet of air entering the mine per minute and measured 6,900 cubic feet of air returning per minute. I then inspected all of the underground workings of the mine and found the workings well ventilated and in good condition. May 9, 1900.-On this day, early in the morning, it was rumored in the town of Gallup that there was powder stored in the W. A. Clark mine, and I immediately went to the telegraph office and sent the following dispatch to the manager of the W. A. Clark mine, which is located at Clarksville, N. Mex. W. L. BRETHERTON, Agent, Clarksville, N. Mex.: GALLUP, N. MEX., May 9, 1900. It is rumored here that there is powder stored in the coal mine which you are manager of, known as the W. A. Clark mlne. If any powder is stored in the mine have it removed at once. Answer. To the above dispatch I received the following reply: J. W. FLEMING, JOHN W. FLEMING, United States Mine Inspector. CLARKSVILLE, N. MEX., May 9, 1900. United States Mine Inspector, Gallup, N. Mex.: We always have stored our powder in a magazine, but just keep a little in the mine for daily delivery. Let me know if this is dangerous. W. L. BRETHERTON, I immediately sent the following dispatch to Mr. Bretherton: W. L. BRETHERTON, Clarksville, N. Mex.: GALLUP, N. MEX., May 9, 1900. Your telegram received. I consider it dangerous to have any powder stored in the mine, and have it removed as soon as possible. JOHN W. FLEMING, United States Mine Inspector. May 10, 1900.--On this day Mr. Bretherton drove into the town of Gallup and informed me that the powder had been removed from the mine. May 12, 1900.-On this date I again inspected the mine known as the W. A. Clark mine. I measured 13,860 cubic feet of air entering the mine per minute and measured 11,310 cubic feet of air returning per minute. The discrepancy between the intake and the outcast was caused by some of the air escaping through an old shaft on the east workings of the mine, which I ordered closed. I found several rooms on the first east entry driven up too far without having crosscuts driven between them, and ordered crosscuts driven between the rooms so as to cause the air to circulate up to the face of the workings. I also found considerable dust on the slope and entries and ordered Mr. Bretherton to have the slope and entries wet down and allow no dust to accumulate in the mine. I also took particular care to examine the place where the powder had been stored in the mine and found that the powder had been removed from the mine on May 9. A new air shaft is being sunk on this mine and when the shaft is connected with the underground workings a fan will be erected 280 measured the mine condition Januar Clark mi measured ings of tE of the ai mine in g March mine.
