SONORA MINES
(Joseph l. Cohn)

CANANEA. Son, Mex, Dec. e The new reverberatory furnace which has been under construction for the past months at Cananea Consolidated Copper company's shelter, was com pleted this week and placed in opera. tion. The new furnace replaces old No. l and takes the same name. stand. ing. as it does, on the spot formerly occupied by the old furnace. The new reverberatory is patterned after the new furnace installed during the year, which has been successfully operating and found to be a great improvement over the old furnace. When No. l finished its last run it was decided to demolish it and replace it by a fur. mace built on the same lines as she new one. This was done and the new No. l is an improvement over No. 9 in some instances.
 The two furnaces are Of the same dimensions. 17x10O feet and the arch also. in like proportion. No. 1, how ever, has beeen greatly reinforced, the walls being thicker and the re. Inducements at the end improved upon. The front contains the same number Of burner apertures as No. 2
 
 the steel plate, this being considera- ply lighter than that in No. ?.
 The furnace has been operating successfully since it was blown in and promises to be able 10 make a longer run than No. 2, which is a great improvement on old No. l. This is the newest reyerberatory furnace in operation ill the copper world.
 
 Supt. Aug Fritche of the Mexican Metals company reDorts excellenet progress in the sinking of the Alacran shaft on the Moctezuma Arizpe prop erty of the company The shaft has reached 8 depth Of l31 feet and con siderable ore is being encountered.
 Ore running high in silver content has been extracted. the values averag- ing around 100 ounces. The lead and zinc each average in the neighbor. hood of IS per cent, while the copper values are around 2 per cent. A small shipment Of the ore was treated al the Calumet & Sonora mill recently which gave good returns.
 Twelve men are at work sinking the shaft and are divided into two shifts.
 It is stated that the Tarasca mine. located near Torres, which has been idle for the past few months, will re sume operations on the first of the year. F. C. Carruthers will have charge of the operations.
 The Cobre Grande mine, located about fl miles below Douglas. in the Cabullona district. is showing up well and some ore has already been shipped to the Copper Queen smelter. Ten men are being employed at pres ent The property is owned by Brad. ley ( Wallace.
 The Elisa mine of the Cananea company was closed down this week for three shifts. The cause was on &C., count of the employees taking, TO rather attempting, the management of the affairs. It seems that the shift boss. Fritsche, was taken in charge of four miners to a policeman and charged with threatening them with "a revolver. FTitsche denies that he Idrew his gun except when he pre-. scented 1t to his guards. As a result of the affair of the company closed down the property and after the men came to their senses the mine was again opened. The four men, it is needless to state, are not now in the company's pay roll. When these men were questioned they finally admitted that Fritsche did not draw his gun, but they knew he had one.
