500 MINING INDUSTRY. 



The eastern part of the ground is better than that further west, and has 

 therefore been more extensively worked. When visited by the writer there 

 was a good vein of smelting ore in this part of the mine, varying from 12 to 

 18 inches in width, accompanied by about 24 inches of fair milling ore. The 

 upper part of the mine is pretty thoroughly worked out, but the deeper portion 

 has been opened by levels, making the ground available for backstoping. As 

 this had been done only to a limited extent the force that could be employed 

 in producing ore was not large. During the season previous to closing the 

 mine its average product was 240 or 250 tons of milling ore per month, yield- 

 ing about $15, in coin, per ton, besides which, during the foregoing year, 

 some 20 tons per month of first-class ore had been sold at the Smelting 

 Works, at an average price of little less than $70 per ton, in currency.^ 



The hoisting machinery on this mine has been provided with a view to 

 permanent work, and is very well adapted to its purpose. It is substantial 

 and is compactly arranged, and but one or two other mines in the Territory 

 are equally well equipped. It consists of two engines, each having a cylinder 

 10 inches in diameter by 20 inches stroke, geared together to drive a com- 

 mon shaft, by which the winding reels are set in motion. The. reels are 

 operated by friction-gear. The style of this hoisting machinery is generally 

 similar to that in use at the North Star mine, on the Illinois lode, which will 

 be described in more detail forther on. 



There are two spools, one of which is devoted to the incline, the other 

 to the vertical shaft at the west end of the mine, near the engine-house, thus 

 commanding three shafts. 



The engines have greater power than is necessary for the work of the 

 mine, and were provided with the view of furnishing power to a stamp mill 

 to be built on the same premises. Steam is furnished by a single locomotive 

 boiler of about 35 horse-power capacity, consuming two and a half cords of 

 wood per day. The machinery is inclosed in a neat engine-house built of 

 stone, with which is connected a spacious shaft-house, covering the ore- 

 assorting floors, forge, and repair shops. The drainage of the whole lode is 

 effected by the pumping apparatus on the adjoining claim. 



^ The relation of the value of the ore to the price paid by the Smelting Works will 

 be shown further on.
