MINING MATTERS.
Deep Mining Will Certainly be Re-
sumed.

MANY of the miners in Arizona are
old Comstockers and will read with in
terest the following from the Virginia
City Enterprise of recent date.
Deep mining will certainly be resum-
ed rpon the Comstock at a very early
date. This statement comes dlrectfr
those most deeply interested IN mining
upon the lode. 1t is nearly as sure as
anything that happened yesterday.
The first work to be done will be at
the Combination shaft. A ropeman
named jackson has already been taken
away from the Hale & Norcross and put
to work at the Combination with an in
crease of pay.
1t is intended to start up the Cornish
pumps and lower the water to the 24OO
level, where the first of three hydraulic
pumps in the shaft will be recovered.
The third hydraulic pump is on the
1900 level. 1t is believed that these
pumps will be found in a retrievable
condition, though some miners believe
they have been eaten through and
| through.
The calculation is TO start two pump
ing plants on the Virginia end of the
| lode-ons at the Combination and the
other probably at the g. d G. shaft
There is a very good Cornish pump at
| the &. & -. shaft that always gave salts
faction, and worked steadily wiILUut
| bother. But the &. il 4. shaft is only
26O0 feet deep, ard would have 10 be
sunk deeper 10 assist IN draining the
| lode. At the Combination shaft, where
there is a duplicate pumping plant To
| that of the G. i O., bulkhead was put
| in on the lower levels which cut off the
north end water from the water that
was being pumped by the Combination
| pumps in the 1855. 1t is believed that
by an intelligent system of bulkheadIng
| the lode can be drained In sections at
will, barring seepage water through the
| ground. The water courses along the
| ledge follow clay seams, and by bulk
heading openings shat tap clay seams
all of it can be held back, except such
| water as seeps through the ground.
The engInery at the Combination is OF
the very best, and can be readily put in
working order. The pipes have been
taken out to the water level and put IN
the Ckollar shaft and incline to run the
dynamos that supply motive power to
| the Nevada mill, but new pipes can soon
| be put in place.
At the c. g. G. shaft the Cornish pump
Ing enginery was somewhat displaced to
make room for the wire rope system OF
transmission of energy, but can also
readily be replaced.
There seems to be tide, or rise and
fall of water in the depths, irrespective
OF pumping operations. Mining Super
| intendents who have taken observations
| of the nights of the water below the tun-
mel level, have observed this fact and
wondered at il, but can offer no explana-
| ton for it. The rise and fall OF the
water. which 50 far has not even been
| connected with the seasons OF the year,
is from ten to sixteen feet.
At the Con. Cal. Il Va, from the read
ing Of the report OF Superintendent ID. b.
Lyman. published in Sundays Enter
prise, il Will be seen that the grade OF
the ore has improved II several parts OF
the mine. The street rumors are TO the
| effect that the mine has not looked as
well, generally, in four years as 1t does
today.
