542 MINII^G INDUSTEY. 



about one ounce of retorted amalgam per ton; this, however, contains suffi- 

 cient silver to reduce its value considerably below that of the bullion produced 

 by those mines whose ores are poor in silver. The average value of the 

 ounce of bullion obtained from the Flack ores is stated at $13, in coin. 



The higher class of ores, carrying considerable silver and combined with 

 lead, zinc, and copper, are reserved for smelting. One lot of nine tons, sold 

 to Professor Hill early in 1869, gave, by assay, seven ounces of fine gold and 

 sixty-eight ounces of fine silver per ton. 



The total production of the mine, since the present management began 

 operations, could not be ascertained. The mine is provided with a small 

 portable engine, of which the cylinder is 9 inches in diameter, that is placed 

 between the two working shafts, but near the western one, commanding both 

 for hoisting. The winding apparatus is operated in the manner already de- 

 scribed, by means of belting. 



Califoenia. — The California lode has of late attracted more attention than 

 any of its neighbors, having, within a year or little more, gained a great repu- 

 tation by reason of the abundance and richness of its ores. It was discovered 

 several years since, and has been worked more or less since 1864. It is nearly 

 parallel to the Flack, and 300 or 400 feet north of that lode. It is traced for 

 many hundred feet in length. West of the dry gulch, near the Stalker and 

 Stanley claim, the lode is known as the Indiana, and has been sunk upon in 

 various places along its course. The only parties working on that part of 

 the lode in 1869 were three men, who had reached a depth of 150 feet, and 

 were taking out good ore of both classes — that is, for smelting and milling. 

 East of the gulch is the principal claim on the lode, formerly known as that 

 of Stalker and Stanley, but the ownership has lately changed hands. This 

 claim is 300 feet long. East of it the lode has been traced and somewhat 

 prospected for a distance of some hundreds of feet, and apparently continues 

 in its course until it merges into or becomes identical with the Gardner. 

 This is not fully established as a fact, and is doubted by some; but it seems 

 quite probable from present developments. 



The Stalker and Stanley claim has been worked to a depth of 475 feet. 

 The main shaft, 50 feet east of the west boundary, had reached that depth in 

 August, 1869, while the east shaft, 130 feet east of the last named, was down
