Where Money Gee. In Mining.

AauA FRIA, January l9.-ICorres- pondence. In looking over some of my old notes of 1879, see some items that think will interest many miners in this section of the country. I worked for the com pany mentioned be low for three years, and know exactly what l am writing about.
 Now, just to show the vast amount of money some men, who have the proper staying qualities. will expend in developing proper ties, l will cite the following from my note book as it lies before me: The boiler house Is 102 feet long by 90 feet wide, containing 10 boilers 54 inches in diameter and 16 feet long, each; one main hoisting room 152 feet long by 40 feet wide, and 67 feet high to base of flag pole; carpenter-shop 50 feet wide by 100 feet long, for framing the timbers for the shaft; machine -shop h0 by 100 feet, and blacksmith-shop 40 by 60 feet. At the shaft is a double cylinder, high pressure, direct-acting engine, both cylinders being con nectcl with one shaft carrying two reels for winding ropes. The en- zine was of 12O0-horse power, and capable of hoistrng 10 tons of ore nearly one mile. Tho crank shaft (which, thank God, was n t mel weighed nearly 50 tons, and was one piece of wrought iron taken from steamship, in San Francisco). The intended piston speed was 900 feet per minute, and would take a cage through the shaft at railroad speed, and wanid make the round trip, at the time I left there, in 1880, 6,2O0 feet in the remarkable short time of 2s minutes The cables used were made of annealed steel wire (put up in Englandl 5 inches wide and three quarters of an inch thick, and wound on the reels like a ribbon on a spool Tho reels used were Ia feet in diameter and would hold 1000 feet of cable, each fitted with powerful brakes worked by haudraulic power, and safety clutches to regulate tho cages in case of accident. The engine foun- dations were of solid masonry, 56 feet long, 3S feet wide and 22 feet deep, to which the engine founda- tions were bolted with So 3-iach and 3s anchor bolts. The plston-rod and all af the valve rods were of steel, and the valves of hard brass. The pumping engine was horizon tai compound condensing one, and direct acting. Tho cylinders were of the following dimensions: The initial cylinder, 39 inchas in diane ter, and 12 feet stroke; the expan- sion cylinder, 66 inches in diameter, and 12 feet stroke. The engine shaft, 20 inches in diameter, Is feet long, and fy-wheel on each end 90 feet in diameteS each wheel weigh ing 90 tons. The engine and line of pumps for the first l200 feet weigh ed 75O tons; the cost price before erection &40,0O0, and was consid- cred the finest machinery that ever left the Risdon iron works of San Francisco.
 Now, my old brother miners and engineers, my reason for giving the above is this, merely to give you an idea of the amount expended for nothing. We put that shaft down 3,lOO feet in the Yellow Jacket mine, to which I refer, Major otey being our treasurer,
 Hoping have not taken up too much space in trying to explain some of the gigantic undertakings and heroic efforts that are made by capitalists to develop our western country. Respectfully, yours.
