a. Not including ores taken out by other parties, purchasing of the company. 



b. Not including revenue derived from hoisting ores from adjoining claims, and from some other sources.- 



c. Estimated ; the company having published no report for the year referred to. 



Note. — The costs of mining and milling are not definitely stated ; as an average, the whole expense, including everything 

 connected with the working of the mine and the management of the business, amounts to about $20 00 per ton of ore. 



The principal group of mines south of the last named, comprises the 

 Yellow Jacket, Kentuck, and Crown Point. These are intimately related to 

 each other. Their ore-bodies form one simple group or system, and the 

 mines, working at about an equal depth, one with the other, are all connected 

 together in their lower levels. The Kentuck, owning but a short strip of 

 ground between the Yellow Jacket and Crown Point, is worked chiefly 

 through the shafts of its neighbors. 



The bodies of ore developed in these mines, and their relations to each 

 other, have been already discussed. A brief statement of the operations of 

 the several companies will therefore suffice for the purpose of this review. 



Yellow Jacket. — The ground of the Yellow Jacket mine is 943 feet in 

 length, measured on the course of the lode, but the organization of the com- 

 pany is based on a length of 1,200 feet, each foot, at least until recently, 

 representing one share of the stock.^ 



The ore-bearing ground of the Yellow Jacket is in two parts, one of 

 which is in the northern, the other in the southern portion of the claim, the 

 intermediate ground, at least in the upper levels, being poor. The northern 



^ If tlie writer be correctly informed, each foot now represents a larger number of 

 shares, probably 20.
