The New Maek Point Viii.

preaching completion, stands the
new Rock Point Mill, and, it is not
exageration to say that when finished
in all its details it will stand a mode
of perfection never excelled in the
history Of quartz mill building in
Nevada. Its crushing
consist of four five stamp batteries,
so geared that each set Of stamps are
run independently of the others, and
either or all of these batteries ale
| kept 10 motion as the circumstances
Of the case may require. There are
eight pans for grinding and amaIga-
mating purposes, four settlers, one
clean up pan and one agitator. There
is also machine shop situated con-
veniently in the rear of the batteries
and a Blake Rock Breaker in posi-
ton where the ore which is too large
for the batteries falls after having
passed over the grizzlies. A thirty
six inch Lefel turbine wheel under
twenty feet of head or water pressure
furnishes the power, it having been
so arranged that another wheel of
the same kind may be readily added,
should it be found that the power
already provided is insufficient. The
ore dump is located on the point of
the hill on a level with the roof of
the mill, and from thence extends
stantial trestle to the grizzlies. The
ore which is already small enough
for batteries falls through the griz-
lilies into bins prepared for its recep-
ton, and the larger pieces pass on
and are landed at the rock breaker
as before indicated. The ore falls
from its own gravity i"to the auto
matte ore feeders &c. G. Stevenson's
invention and patent) and is by them
regularly and evenly supplied to its
| batteries. The steam necessary for
heating the pans is furnished from a
fine large tubular boiler back of
which stands the returt. Both the
boiler and retort are substantially
walled in with brick and are on what
may be ed the ground floor of
the mill. Ample preparations have
also been made for saving the sui
phurets, slums and tailiugs. The
water is taken from the Carson Riv-
er about two hundred yards below
the stage road bridge. The dam is
constructed of rock and timbers aud
appears sufficiently strong and sub
stantial to Withstand the wear and
tear of many years. Between the
abulments Is an apron two hundred
feet in length by seventy feet in
width made of two in CHI plank, most
securely spiked TO the heavy timbers
below, over which the surplus water
is permitted to escape, that which
revolves the mill machinery passes
through an equally substantial gate
way, constructed of framed timbers
aud plank, into an ample ditch or
canal, which conducts the water to a
hume through which 1t passes the
distance of one thousand feet, aud is
finally discharged upon the Turbine
wheel. The flume is also a very
substantial structure, four feet in
depth and eight feet in width. The
excavation of this ditch was done by
Mr.. McCutchen who is an experience
ed hand at this kind of labor. He
Is the right man in the right place
when there is any eScavating to be
done. This eutire work has been
constructed from plans drawn by
Mr.. ID. IL. Bisbee, for many years in
the employ of the Banana nm OF
Virginia CITY, aud also under his i'm
mediate supervision, and the exact
ness with which each part fits into
its attendant part and performs the
duties which were assigned to it.,
proves Mr.. Bisbee to be a master OF
his profession and a "workman that
needeth rot to be ashamed" The
milling aud reducing the ore and ex
tracing the precious metals there
from, Is under the able management
OF Mr.. VIM. Shirley, well known in
| milling circles as one of the most eX
