400 feet above the lowest depression, and 2,739 feet distant, to which point 

 the water is forced by its own pressure in the inverted syphon. At this sta- 

 tion other pumping works are established, using four Martin pumps, and rais- 

 ing the water to Treasure City, 682 feet higher. This is accomplished in a 

 7-inch pipe. The supply pipes for the towns are 3-inch tubing. The capacity 

 of these works is stated by the engineer, Colonel Buckley, at 2,500,000 gallons 

 daily. The supply at the spring is said to be not less than 5,000,000 gallons. 

 The cost of the works is stated at $300,000 in coin. They commenced run- 

 ning in October, 1869. 



Newark District. — The Newark district is 25 or 30 miles north of White 

 Pine, being by that distance nearer to Elko, its point of connection with the 

 Pacific railroad. It was organized in October, 1866, and, until eclipsed by the 

 later developments of White Pine, was the principal mining region in that part 

 of the State. It is on the east slope of the Diamond Range. The principal 

 developments have been made by the Centenary Company, who own claims on 

 several veins, the most important, according to present appearances, being the 

 Chihuahua. This ledge occurs in an outlying spur of the range, in which the 

 limestone strata appear to strike northwesterly, dipping flatly to the westward. 

 The vein has a similar course, but nearly a vertical dip, inclining a little to the 

 westward. Its croppings are very prominent, standing up 30 feet or more 

 above the surface. The vein is from 6 to 15 feet wide, and is filled with 

 quartz and calcspar. The ore, which is usually associated with the former, 

 consists of antimonial and sulphureted combinations of lead, copper, and silver. 

 It requires to be roasted for the extraction of the latter. Its average yield 

 appears to be between $80 and $100 per ton. The ledge and its inclosing 

 rocks are cut through transversely by a deep canon, which affords a favorable 

 opportunity of working the mine by means of tunnels or adits. Two or three 

 of these have been driven, one above the other, and several hundred feet long. 

 As nearly as could be ascertained by the writer, about 900 or 1,000 tons of 

 ore have been produced, yielding something less than $100 on the average. 



The company own a fine mill, situated about three-fourths of a mile from 

 the mine. It contains 20 stamps, 8 reverberatory roasting furnaces, 10 pans, 

 and 5 settlers, driven by an engine of 140 horse-power. It is said to have 

 cost $130,000 in currency. The cost of the mine improvements is stated at 

 $50,000 more.
