CENTRAL KSD EASTERN NEVADA. 367 



body is a fault, or slide, which appeared to be the same that had been encoun- 

 tered in the upper levels, and which has already been noticed. The distance, 

 upward, from this lower level to the deepest level opened by the incline is 230 

 feet, measured on the dip of the ledge, and a large portion of this ground 

 appears to be productive. 



At the time referred to there were 45 men at work in the mine. The 

 production of ore was varying between 100 and 200 tons per month. All 

 hoisting and pumping was done through the Lane and Fuller shaft, the old 

 works at the incline having been abandoned. The shaft was still sinking and 

 had reached a depth of 500 feet. It is sunk in three compartments, two for 

 hoisting and one for pumping. It is cased with plank, no heavy frames of 

 timber being required. The shaft is provided with two engines, each having 

 cylinders 10 inches in diameter and 20 inches stroke; one of these is used 

 for hoisting, driving friction-gear; the other is employed in pumping; but 

 both are so placed that one may do the work of the other if necessary. The 

 pump is a force-pump, six inches in diameter and four-foot stroke. The object 

 of this shaft is not only to work the North Star ledge, but to afford the means 

 for the discovery and development of other veins. It has already cut a num- 

 ber of ledges, some of which are thought to be identified with some of those 

 cropping out on the hill below the shaft ; others of which are claimed as new. 



The veins cut in the shaft to the depth of 300 feet are described as 

 follows : 



Depth. 



Black ledge, cropping at the surface, near the shaft, cut at 10 feet. 



Florida, cropping at the surface, extension of Florida company's vein 103 feet. 

 Oleander, cropping at the surface, extension of Oleander company's 



vein 130 feet. 



Miner, claimed as hitherto unknown 140 feet. 



Tyler, claimed as hitherto unknown 160 feet. 



Dyer, claimed as hitherto unknown 233 feet. 



Warren, claimed as hitherto unknown 285 feet. 



The last named is described as four feet thick and carrying valuable ore. 

 It has been worked to some extent. At a depth of 400 feet, a drift is car- 

 ried in a northeasterly direction from the shaft, which at a distance of little
