tain uniformity in course, dip, and width, and in the character of its ore. 

 The walls are well defined, and both foot and hanging walls are the same 

 metamoi-phic slate. The ore is very much decomposed, and consists chiefly 

 of oxidized products, containing a good deal of "base metal." The silver 

 occurs in the form of sulphuret. The vein rock is cut by seams of soft, white, 

 clayey material, which carries finely disseminated silver sulphurets. 



The Golconda mine is one mile and a half north of the small town of 

 Cumberland. A force of thirteen men was employed in this mine in the 

 summer of 1868. The company have a mill situated seven and a half miles 

 north of the mine, which is furnished with eight stamps, five Varney pans, 

 and eight Knox pans, used as settlers. The mill was then working about 

 10 tons per day, of which the average yield was $35 per ton. 



The other mines had been less developed than the Golconda. The 

 more prominent of these were the Cumberland, Register, and Jeiferson. 

 The last named, at the south end of the vein, near the '^ split," has an incline, 

 sunk to a depth of 65 feet on the vein. The mill assay of eight tons of ore 

 from this claim gave $48 per ton. 



Battle Mountain Disteict. — This district, about 30 miles further east, 

 is one that is rapidly growing in importance. It is south of the Humboldt 

 River and near the railroad. The station of the same name, by which the 

 mines of this region are made accessible from the road, is 379 miles from 

 Sacramento. The district is about 12 miles long, in a north and south direc- 

 tion, by something less in width. It lies on the west side of Reese River 

 Valley, and in the eastern foot-hills of the Battle Mountain range. The river 

 bed here is dry during a portion of the year. The mountain streams, in the 

 neighborhood of the mines, furnish water enough for mining, milling, and 

 domestic purposes, and, in some cases, for driving power. There is a fair 

 supply of wood and timber, suitable for fuel and for use in the mines, in por- 

 tions of the district and in the adjacent country. 



The principal mine in the neighborhood is the Little Giant, chiefly 

 owned and worked by Mr. G. W. Fox. It is eight miles from the railroad 

 station. The vein, on which this mine is opened, was first prospected in 

 1867, and was developed by a small force until May, 1868, when the work 

 was prosecuted with greater vigor. During the following summer a five-
