THE COMSTOCK MINES.

whicli the winding reels are operated by means of clutches and brakes, as 

 already described. The water is removed from the mine by means of vessels, 

 raised and lowered like the cages, and operated by the same machinery. A 

 pumping engine is provided, but the pumps are not yet in place. 



There are four tubular boilers, 16 feet long and 52 inches in diameter. 

 The whole of this estabhshment is inclosed in a large building, with which 

 are connected carpenter and smith shops for all necessary work of construc- 

 tion and repair. The total cost of sinking this shaft, and establishing the 

 surface works appertaining to it, and conducting the explorations in connec- 

 tion with the same, amounts already, according to the reports of the two 

 companies, to about $400,000. The following statements present a summary 

 of the operations of the two companies, Imperial and Empire.
