chlnery Of the Belcher Mining Com
pany at the main shaft Of their Valua-
BILE mine being completed and now in
full and efficient operation, we will
give a description Of the same for the
benefit Of those who take an apprecia-
tive interest In such matters.
The shaft
Is In perfect order throughout Its vari-
Gus compartments, provided with the
latest and most approved styles Of ore
hoi.ting cages, wire cables, etc, and Is
$50 feet deep perpendiculSrly. From
the s5O-foot level the shaft Is contin-
ued In the form Of IN incline TO the
l2OO.foot level Of the mine, following
the dip or inclination Of the ledge
about As degrees-at the west wall.
Through this shaft Is hoistcd the daily
orc yield Of the mine, which, during
the past week, has been about $50 tons
per day.
The HeistinE Machinery
At the surface is among the most
powerful on the Comstocs, and capable
Of working the mine to a much greater
dsp.h than at present. The hosting
or gsllows frame owe the shaft Is 10
tces high, the reels, brakes, etc. OF the
moot substantial description, and the
hoisting Is done by two powerful,
horizontal engines. from the kisdon
Iron Works, San Francisco, with ~
inch cylinders and 30-inch stroke. The
main building covering the shaft and
hoIsting machinery Is SIS by III feet
In size. In it Is also a neat little u
zine Of l0-inch cylinder and "a inch
stroke for running the blowers which
drive air down into the mine, also an
ag compressed air engine,

The Boilers.
In the commodious boiler room, III
by 40 feet In size, at the north side OF
the main building. are the six boilers
which supply the steam power, Tour OF
them being In use at time, leaving
two snare ones for an emergency.
They are l6 feet long feet long. oy o
inches In diameter, containing 40
3.inch tubes each. Two neat little
Blake steam feed-pumps, back Oh d
boilers, inject the requisite supply o.
water into the boilers, anu are also
prepared for use In case Of fire, having
hose ready for attachment. lhey gan

to twenty. Under II pair OF boilers
Rocky Mountain coal has been USED LOT
about a week, and wood under the
other pair, burning 5}a tons OF coal or
AZ cords Of wood per day. IL Is im-
possible to decide as to the relative
merits, efficiency, or cheapness OF tue
two kinds of fuel without 4 conSldera-
bly, longer and o satisfactory 'rlS''
New style Of Boiler.
At the north side of the main ouild-
Ing. In a room IS by Is feet In size, Is
one Of Roots wrought iron, sectional,
safety boilers, lately introduced and
being set up for Use. It is a queer ar
rangement, being simply a combina-
ton Of about $50 four-inch iron tubes
about 10 feet In length arranged in
square form, within a brick furnace
Enclosure, and all connected NJ the
ends, leaving interstices between each
for the heat TO pass. It Is clained that
tbi, style of boiler Is not only safe from
sxnlosIon, but will make steam faster
than any other.
The Carpoater shop
Adjoining the south side Of the main
building Is 80 by 90 feet in size and
here are fitted and prepared any unu-
,ual timbers required in the mine or
works, the ordinary styled timoers OF
tbe mine being all prepared ready ior
nee by machinery, at Carson, before
hrinoing them over the railroad. Here,
too. the planking for the fioorings IN
the mine are sawed to the proper
length by a circular saw in a swinging
frame. A timber car Of peculiar shape
for running up and down the incline
