stroke, and one 15-inch, 4-foot stroke |
Knowles pumps, throwing water
400 feet to the 100 foot level. There
are also in This shaft two smaller
pumps, and one 12-inch, 2-foot
stroke pump. the latter being held
as a reserve in case of accident to
either of the. others. In No. 2 shaft,
on the 6o0-foot level there are one
finch plunger, 2-foot stroke, and two
smaller pumps, throwing water 800
feet to the first level. On the TOO
foot level there is 14-inch plunger,
3-foot stroke, pumping 200feet to the
fifth level, and on the S00-foot level.
a 17-inch plunger, 4-foot stroke-the
largest pump III any mine in the
west-capable of throwing 1,400 gal
Ions of water per minute 800 feet to
the fifth level. at every station
there are extra pumps ready for use
in case of mishap. From the
lOO-foot level, the water flows to the
surface in the gulch below, through
Union tunnel, pouring out at the
steady flow of 1900 gallons min
ute. All the pumps are ope atad by
steam from the fourteen boilers
at the surface, and which also sup
ply the steam for the two 25O-horse-
power hosting engines. Were it
not for the water the Ontario stock
holders would often receive extra
dividends. This fact will be under
stood when it is stated that the
daily consumption of coal at the
mine, chiefly for pumping, is forty
six tons, the cost being $3.50 per
ton. One of these days the cost of
getting rid of the water viii be
greatly reduced. Last summer the
HERALD gave the particulars OF the
starting of tunnel below the mill,
a nile and quarter down the can
yon from the mine. This tunnel
has now been bored to the length of
nearly 600 feet, and is steadily adj
vancing towards the Ontario work
ingS, which it is expected to reach
some time in 1888. 1t will run into
the mine on the 6O0-foot level, and
drain the water from above that
point, as well as provide cheaper
and easier means for transporting
much Of the ore to the mill.
NO. 3 SHAFT.
Nothing has been said of No. 3
shaft. Westward from the present
hosting works, across the gulch,
over on the Last Chance ground,
1 900 feet away, loom the new
works." that is to say, the building
looms. This is a massive structure,
perhaps 100 feet in height and hav-
ing proportionate dimensions, with
LIS, lean-to's, ETC., for boiler houses,
and machine shops, and
such other departments as are ne
ceSSary to extensive and complete
hOiSting works. The shell" ONLY
of this immense building is com.
pleted, and the iron roof fastened,
while inside the hammer, the auger,
the saw, are in constant motion,
framing large timbers, such as do
not grow in Utah, and preparing for
the work to he done at No. 3. Be
meath this building, and down now
nearly 800 feet, is a broad shaft, of
three compartments, gradually near
ing the ore body, which it will prob
ably cut at depth of between l,5OOI
and 1900 feet. When this is accom-
plished the Ontario will be at. a
loss to know what to do with its
ore, for it's present mill capacity is
not more than half equal to what
the output of the mine might be
made now. However, as some time
will necessarily elapSe before no.
can be made seryiceable as an ore
or water hoist, perhaps a way for
of the extra ore will then
be devised. Now, hosting works
are immense arrangements, and this
particular one, it is proposed, shall
be like the Ontario mine, the most
if not the largest in the
United States. This will be under
stood when we say that the original
cost of No. was 100000, and oil
No. 2 S150,000, and that No. 81
will cost, it is estimated, between
S225.OoO and $25O,OOU. This, of
course, includes the machinery,
which forms a large share of the
expenditure To obtain an accurate
idea Of where all this money can
be wisely expended one would have
to visit the works, and see what is be-
ing done, but we will attempt to con-
vey an impression of the thorough
ness as well as the expensive char
acter of the work, by briefly de-
scribing portion of it, namely: the
pump pit or foundation. In order
to reach firm bed it was found
necessary to dig a pit fifty-two feet
deep, when solid rock was encoun-
tered, and from this they are build
ing piece Of masonry that will
stand till the end Of the world, defy
ing earthquakes and grimly smiling
at mundane commissions The aver
age depth of the foundation is forty
five feet, and the width tWenty-one1
feet, and when finished it will con-
tain 5000 tons of rock, firmly united
by 600 bushels of Portland cement.
Not only this, but it is tied together
by numerous iron anchor bolts. three
inches in diameter, and 36.5 feet
long: The coping is OF cut Cotton
wood granite. transported by rail,
the massive blocks being from five
to seven feet-long, two to three feet
wide and two feet thick. Other
large blocks of rock have been
brought from the sandstone quar-
ries at Croydon, in Weber CANYON,
