Conditions of the futuee affecting costs. — The Comstock lode, 

 judged by present appearances, would hold out but doubtful promise for the 

 future, if there were no hope of greatly reducing the present costs of mining 

 and milling. 



There has been, during the last few years, a steady decrease in the 

 value of the ores raised from the mines, as the foregoing table makes plainly 

 evident; while some of the mines that, until lately, have contributed most 

 largely to the annual bullion production of the lode, are rapidly exhausting 

 the deposits hitherto supplying ore, or have already done so. The deeper 

 explorations of those mines which furnished large products from ground 

 within 500 or 600 feet of the surface, such as the Ophir, Gould and Curry, 

 Chollar-Potosi, Empire and Imperial, have thus far afforded little or no en- 

 couragement; so that, while fortunate discoveries of new ore-bodies in the
