explored, had been stoped out in 1868, shortly before the mine closed; but 

 there was still a good show of ore between the 400-foot and 500-foot levels, 

 where the ground was standing. According to the quarterly returns of the 

 county assessor the product of this mine, from September 30, 1866, to June 

 30, 1869, amounted to about 1,000 tons, yielding about $236,000 in coin. 



The profits of this work are said by the superintendent, Mr. E. A. Sher- 

 man, to be about $100,000, currency, which amount, however, has been re- 

 invested in machinery for the mine, and in the prosecution of other exploring 

 works. These latter consist mainly in two vertical shafts, located on the 

 ridge of the hill, or "divide," overlooking the opposite vaUey, These shafts 

 were projected to be sunk to the depth of a thousand feet or more, with the 

 view of striking and working some of the ledges belonging to the company 

 and cropping out on Lander Hill; also, with the somewhat visionary expecta- 

 tion of finding the many seams and fissures of the surface concentrated in 

 one grand vein below. The Sherman shaft had reached a depth of 250 feet. 

 It is 15 feet by 5, divided into three compartments, cased with three-inch 

 plank. It is liberally provided with hoisting power, an engine, with cylinder 

 of 16 inches diameter by 34 inches stroke, driving friction gear for hoisting, 

 and furnished with pumping gear. Two tubular boilers, 50 inches in diam- 

 eter, supply steam. The sinking of the shaft to depth mentioned above, and 

 equipment of machinery, cost $56,000. The Burns shaft is located 1,500 

 feet west, and is similar in character and purpose. It is not yet provided with 

 machinery. It is 90 feet deep, and has cost $12,000. The work on both 

 these enterprises had been suspended in the summer of 1868. Neither had, 

 at that time, made any important developments. The mine itself suspended 

 operations in 1869. 



DiANA.^The Diana is situated below most of the important veins on Lan- 

 der Hill, and is on the western portion of the ground, its ores partaking of the 

 character of the baser zone, that hes west of the richer mines. Its course is 

 north 15° west, true, and it dips from 45° to 50° easterly. The claim is 1,200 

 feet long. On the surface the vein was stripped for 180 or 200 feet in length, 

 yielding rich chloride ores; in depth it has been worked some 300 feet, yield- 

 ing some ore of high grade, but the greater part of it is mixed with base 

 metals, which not only diminish the value but increase the cost of treatment.
