MINING INDUSTET. 



which is 10 per cent, of all the expenses of the company. As the mine 

 has no connection with its neighbors, the shaft can only aid in the develop- 

 ment of a small part of the ground for which it would be sufficient if the claim 

 were longer. The cost of hoisting works, the consumption of fuel, labor of 

 the engineers and some other men, the cost of superintendence and other 

 management of the company's affairs, are nearly or quite as much as they 

 would be if the production of the mine were ten-fold greater. Thus the costs 

 per ton are much increased, and ore, rich enough to afford a profit under fa- 

 vorable circumstances, is produced at a loss under existing conditions. 



This is true of many of the mines in Colorado. Some of the best lodes, 

 apparently possessing all the necessary qualities for profitable working, under 

 one comprehensive and economical management, are divided into a multitude 

 of short claims, worked independently of each other, at great expense, and 

 losing their possible profits for the lack of consolidation. 



The following statement shows the operations of the mine, in detail, for 

 five weeks, from October 9 to November 13, 1869:
