 rely satisfactory and has reduce le cost of cutting and handling tim CTS very appreciably The Copper Queen mines used for the year in the eighborhood of eighteen million feet timber.
 The central steel sharpening plant which replaced four small plants is regarded by all who have visited it, ] and possess knowledge in different dis tricts of such plants, as being one of the most efficient in operation any where. The cost of sharpening steel has been considerably reduced. The bits all being made by the same men and in standard machines are exact as to size and the tempering of the | steel for the same reason is most sa:- isfactory This steel sharpening plant is recognized by experts as one of the best of its kind in the United States.
 An interesting operation that was commenced the latter part of the year was the concreting of the Sacramento Shaft Since it was necessary to ope-
 
 eight hour shifts per day. it was neces- sary to develop a system of concreting | in which one set of concrete could be put in during one shift of eight hours. ] A set of steel forms were made for the purpose and a number of sets of new plan. After five sets were put in 
 i it was evident that the plan previously outlined was success and the work is progressing rapidly at present. Three hundred and five feet were put in from October 4th to December 31st, 1915. l There are three complete sets of forms and the shaft is being concreted at three different places.
 Fifteen lessees are. working on the surface of the Copper Queen ground and are taking out and shipping to 1 Douglas shelter considerable ton mage each month. This is almost all copper ore.
 The record of the Copper Queen i mines for 1915 in regard to accidents is one of which both the company and the men may well be proud and gees to show what can be done when CO., operation in safety work is obtained. Fatal accidents in the mines for the year were two, as compared to six in | 1914. The serious and minor acci- dents were also considerably decreas- ed. A plan has been worked out whereby the ten shift bosses who have the least number of accidents for three consecutive months receive bo- |! nus. This method insures the strict est attention at alltimes of the bosses in regard to matters of safety. In case of fatal accidents. or serious in uries, the Safety First Inspector pub fishes bulletin describing the nature { of the accident, surrounding circum- stances, the cause if it can be ascer- tained and if possible the resporsibil- ity if the same can be determined. Some of the safety appliances put in i during the year, 1915, were installa- tion of Welch safety devices on all main hoist engines. These devices make it impossible for the engine to go beyond a certain speed, pull the cage into the head frame, or drop it beyond a certain distance below the bottom of the shaft The latest type of springs are used on all cages, daily | examination made of the same by a competent man and an experienced hoisting engineer inspector has also been appointed whose duty it is to make daily inspection of all hoisting engines.
 The mine fans in the Lowell ard Sacramento divisions have been re- placed by fans of larger type, so that the full quantity of air delivered at present in the two divisions is about 13O,000 GU. ft.,s per minute. Since these blowers have been installed, Di- visions have been wonderfully improv- ed, as there is ample air for the men and the mines are very much cooler than formerly. There were two mine fires during the year, one in the Hol- brook and the other in the Lowell. Both these fires started near old fire stopes. The one in the Holbrook was extinguished in a short time, while the Lowell fire is sealed up by con crete bulkheads and efforts are being made to drift over the fire areas and get water into that portion of the mine with a piew to putting it out.
 Altogether, 1915 was one of the best years in regard to production and costs that this company has ever had and will compare most favorably with that of any preceding year. Notwith- standing the high wage rate the ton mage costs have been considerably lowered, and as the grade of ore for the year was kept at high level the per pound copper costs are probably the lowest in the history of the com pany. This is an accomplishment of which the operating department and all connected with the company should feel proud.
 SOME SHATTUCK FACTS.
 The report of Supt. Arthur Houle of the Shattuck mine for the 27 days, ending December 31 contains much in teresting information. The ore de velopment news is especially impor-
