174 MINING INDUSTET. 



well as the prospecting of tlie ground in depth ; but if ore-bodies exist there 

 they have yet to be discovered. Since the beginning of 1870 an assessment 

 of $10 per share has been called. 



Hale and Noeceoss. — This mine is situated next south of the Savage. 

 Its claim covers 400 feet along the length of the lode and the present organ- 

 ization of the company is based on a subdivision of each foot in 20 shares. 

 Operations vv^ere begun in 1861 or 1862. A shaft was located near the crop- 

 pings of the lode and was sunk vertically until striking the west wall at a 

 depth of 535 feet, when its direction was changed so as to follow the inclina- 

 tion of the foot-wall of the vein, reaching in that manner a vertical depth of 

 780 feet. During the progress of this work exploring drifts were made from 

 the shaft at various depths, and though the ground in the upper levels was 

 carefully and persistently prospected, no important bodies of ore were found 

 until attaining a depth of about 500 feet. Here, late in 1865, a very valua- 

 ble deposit was discovered, and the company then entered upon a very pros- 

 perous career. In 1866 a new shaft, located in the eastern country-rock, and 

 resembling in general features the shafts of the Gould and Curry and the 

 Savage, was begun and has since served in the development and exploitation 

 of the deeper portion of the mine. It is now between 1,000 and 1,100 feet 

 deep. The present sources of ore in the mine are not confined to the lower 

 levels, as the old works are still mined through the shaft that was sunk on 

 the croppings, and, in the summer of 1869, were contributing largely to the 

 general product. The ore-bodies of the mine and their mode of occurrence 

 have been noticed in the foregoing chapter. The deep shaft of this mine re- 

 sembles those already described but has only three compartments. One for 

 pumping, is 5 feet square ; the other two, for hoisting, are 4 by 5 feet, in the 

 clear. The pumping and hoisting works have been already referred to. 

 Their method of arrangement is shown on Plate XIII. 



The pumps are 11 inches in diameter. The pumping engine has a cylin- 

 der 20 inches in diameter by 48 inches stroke. The hoisting engine has 

 an 18-inch cylinder with 30 inches stroke. The winding reels are 10 

 feet in diameter and have a winding capacity of 2,300 feet of flat steel rope, 

 4 inches wide by § of an inch thick. The method of controlling the reels
