1xrERIAL PuxrrSo MAcnsrnr.-

IMPERIAL PuxrrNa MAcMNERY.-
We are pleased to note the prepare.
lions made by some Of the companies
operating on the Comstoek, for carry
ing OF mining operations at great
depths by the Introduction Of ma
chinery commensurate with the work
to be performed. We give herewith a
somewhat detailed description Of the
pumping machinery now In operation
in the Imperial mine The foundation
consists OF "a feet Of stone laid In ce-
ment, to which the pumping machinery
Is anchored by bolts having eyes turned
ut the bottom, through which bars Of
iron are passed. 30 that each bolt has
the weight Of the entire foundation,
estimated at 5000, 900 pounds. The
engine, l69-horse power, has a 22.inch
cylinder and a 42.inch stroke ; length
Of walking beam "a feet. The weight
Of the engine he'd, complete, Is ID tons.
The engine shaft Is nine inches In
diameter and has two fiy-whects Of II
feet in diameter and weighing about
IL, 600 pounds each. There are two
pinion-wheels on this shaft for driving
the spur-whesls /; also q reel with q 2I
inch hemp cable for handling the
pumps in the shaft. There are two
spur-wheels, each IL feet 6 inches In
diameter. II inch face and Weighing
20. 600 pounds each. These wheels are
placed Is inches apart, and the wrist
pin, 10 which Is attached the pitman
rod for working the pumps, passes
through both wheels, thus insurlng
great steadiness and strength. The
whole foundation Of woodwork 10 made
Of California spruce, each n OF the
timbers being "a by 26 inches. This Is
the first pumping machinery so al
ranged, and from the satisfactory man.
e in which it appears to work. we
have no doubt the plan will hereafter
be universally adopted for similar
work. The spur-wheei shafts are 10
inches In diameter. There are six 10
inch pumps In the perpendicular shaft,
and two OF 9-inch In the incline shaft.
The pumps are all Of the kind known
as :" plungers." The pump rods are Of
timber, IL inches square, and heavily
strapped with iron. The weight of the
rod Is counterbalanced by four balance
hobs, carrying 100000 pounds Of bal.
last ; the chord to the main bob Is "
by q inches and 80 feet in length.
The pumps at present are pumping
from a depth OF LOO feet, and with
the present quantity of water will re-
quire to be run not to exceed eight
hours each In q. The capacity OF
this machinery Is estimated to be equal
to draining the mine to a depth OF
5000 feet. Every portion Of It Is made
In the best manner, and certainly It 10
not equaled In power or completeness
by any on the Pacific coast, and so far
as we know, BY none In the United
States. As showing the energetic
character Of this machinery. We may
mention that ON being set to work yes
terday afternoon, it pumped up to the
surface %. $50 gallons Of water ia the
short space Of 1.-TWO hours!
GRAND BILLIARD TouRNAMESr.-
This evening there will be a grand ex-
hibltlon billiard contest at Odd Eel
lows new Hall, Virginia City. The

there will be a four handed four-ball
game, in which all will participate.
The exhibition will conclude with
some fancy shots by McCleery aud
Kraker. Seats will be reserved for
ladies and their escorts who wish to

taken impression that ladies who pur-
pose attending the ball tonight will
not have time to witness the billiard
tournament. There will be ample
time to attend both, as the billiard ex-
hibition will commence at 8 sharp aud
onclude at 9}2 or 10 o'clock.
