of the boiler, similarly to the Scotch
marine.
This mine lies low on the south side
or the HILL and owing to the immense
seepage. has more water to contend
with than any other single mine in the
district. 1t is therefore provided with
pumping machinery of unusual power.
On the 1000 foot level there is Rider
compound pump capable of raising 900
gallons a minute / 900 feet. This is the
largest and most powerful pump in the
Butte district. 1t is reinforced by
Nordberg. with capacity of 400 gal
IONS minute, raised height of 1000
feet. The Nordberg is likewise upon
the LOO foot level. There is also No.
II cameron pump on the same level.
rms pumps from the 1000 foot to the
7oo, and its capacity is $50 gallons
minute for height of 400 feet. Finally
there is a Wellington pump on the 700
loot level which raises the water to the
surface from that point at the rate of
300 feet per minute. At the present
time the quantity of water being pump
ed is about 700 gallons a minute. 1t is
high colored and evidently heavily
charged with copper
There are two water columns in the
shaft, one of 10 inches and the other of
nine. Both are Of iron and lined with
wood. There is also a x-inch brass
water pipe from the surface down to the
1G0-foot level In addition to these there
is five-inch steam pipe which works
the pumps, and four-inch line for
the transmission of compressed air.
Quite worthy of mention as part
of this plant is the hydraulic power on
the 900 foot level. This was designed
by Assistant Superintendent Batter
| man. and Is used in repairing the pipes.
1t is so arranged that when it Is neces-
sary to take out length 1t clutches
the pipe while the hydraulic pressure
applied, raises the entire column suffi-
GENTLY to admit of the operation The
weight of the largest column is said to
be 10 tons. but the machine lifts it
with ease and does it's work admirably.
The other machinery of this mine is
not of unusual power, but ample for the
work it has to perform.
The immense stream of water forced
from the mine passes over sluices, fill
ed with old iron scraps, which precipi-
tate the copper contained in the usual
way--the sulphurc acid which holds
the copper in solution, dropping it and
taking up iron instead, the acid hav-
ing a stronger affinity for the iron than
for copper. These sluices are worked
by lessees. and the copper savings must
be very considerable in amount.
At the Berkeley and No. 8, the plants
are small, but ample. Neither mine is
uoWn " any Sieal uep'n, the bei heiey
being $50 feet and No. 3, $50. The Grey
rock is down 1850 feet, the Bluejay
1850. and Silver Bow No. l is 1000 feet
in the shaft. but the workings in the
Silver Bow are all from the 1000 foot
| level upward.
| More detailed mention will be made
of the Greyrock Bluejay. Berkeley and
| No. in subsequent issues. The reduc-
| ton works must also be reserved for
| separate mention, in order that this
article may not be unduly extended.
In conclusion, it may be simply remark
| ed that since the reorganization the
company has worked in the face of
many complications and disadvantages:
but that there is great future before
| it, no one familiar with the properties
| has the slightest doubt.
