powder,
a small
of shaft-
;e, 300 lb,
The main opening is an incline shaft, 6 x 8 ft. in clear, 450 ft,
deep, and provided with a skip road, consisting of 6 x 6's, shod
with iron straps, and a good ladder road. Said ladder road is
not provided vrith at at ions as: it ie on the incline, The average
dip of a shaft is 4b degrees to the north.
The other workings consist of a 100 ft, level, called the 1st level,
(old and abandoned) 230 ft. level, called the 2nd level, (old and
abandoned) 330 ft, level, called the 3rd level, running 200 ft,
wrest, and caned on the east. At a point 238 ft, S. I", of main
shaft, a shaft is sunk on the vein, which connects with each of the
above levels, thus serving as an air shaft and exit. At the
present time, the only work carried on, is that of sinking the shaft.
The hoisting is done with a one ton skip, 22" x 22" x 36", on vahich
men are raised and lowered. Fleight of load hoisted, 2500~f, distance
hoisted, 450 ft, A good 5~8^ steel cable, provided with socket,
ie employed, same having been in use for one year. The bell line
employed, is a wire line placed in skip rope, adjacent to the ladder-
way, same being attached to gong. The Colorado code of signals is
employed, though no copies of same v/ere found posted. The method
of ore extraction employed, is that of over hand stoping, vaith hand
drills. The timbering is square set (sawedl in shaft, s.nd stalled
timbering in atopea- good red spruce and pine being employed, One
ton steel end dumping care, are employed. 'fhe trac]c is furnished
with 8f~ steel rails. The drainage is affected by hoisting 200 gals,
water per hour, vrith skip. Ventilation, natural, and quite
sufficient, Sanitary conditions, i'air. hxit is had by both
main shaft, and shaft situated 23ES ft. west of same, which oon-
neote vaith 1st, 2nd, and 3rd levels as above stated. Candles are
used for lighting underground.
