EUREKA MILL.

! our State, the discovery and develope
ment of rich mine, is not only fortune
to the lucky owners, but great benefit
to the whole community. But as mines
| and rich ore alone, are of no value with
out process and machinery to extract
the precious metal, so next in rank
comes the invention, and combination OF
machinery the best calculated to extract
the greatest per cent. of value from the
ores, at the least cost to the owners. The
Eureka mill perhaps, comes the nearest
to perfection of any mill on the coast; as
it combines the largest amount of ma
chinery of the most approved patterns,
under the charge of one superintendent,
the successful working of which depends
on his skill and business capacity. Thus
mill was commenced in July 1871 under
the direct charge of S. Fountain as Gen
eral Superintendent of Construction and
Mechanical Engineer, and the late Il. A.
Chase as Civil Engineer. 1t Is located
on the Carson river about two miles be-
low the Santiago mill, and Is run by
water, using the river as motive power.
About half mile above the mill the river
is damned by an immense structure of
wood over two hundred feet in Length, SIN
ty-one feet wide at the bottom and sutfi-
cientlv high to raise the water twen-
ty-four feet to the apron, with abutments
eight feet higher. This is built of tim
bers fourteen inches square, bolted to-
sether and filled with rock. In the con-
struction of this over six hundred thou
sand feet of timber were used. The
fears of its destruction by the floods that
sometimes spread far beyond the banks
Of this stream were all banlshed by the
flood of December last, which We're una
bic to stir it in the least, and is now con-
sidered as much q fixture as the noun
tains themselves A hume carries the
water to the wheel. This tiume Is twelve
feet wide and five feet deep, and has a
capacity of eight Thousand cubic feet
per minute. The wheel is a Laffelle
Turbine, fifty inches in diameter, and the
fall Is thirty-eight feet. The registered
power of this wheel with the gwen fall
and using that amount of water is Al
horse power. The mill is very large and
built on a side hill in such q manner that
the ore delivered at the stamps wo'ks down
grade through all the manipulations Of
reduction. There are sixty $40 pound
stamps, with fall of ten inches, dropping
ninety times minute. Twenty-slx pans
grind and amalgumate the pulp
and proportionate number OF settlers,
agitators, and Stun tanks finish the
process of reduction The capacity of
this mill, running full speed, is two hun
bred tons per day, and averages about one
hundred and eighty of ore reduced. A
Ifh fhe /
Virginia and Truckee Railroad, receiving
the ore from the latter road through a
dry chute four hundred feet long, stand
ing at an elevation of 81 degrees from the
pl ne. The cars of this narrow gague
mold about four tons and are hauled up
the road by horses and return by grayita- |
ton to the dam down uniform grade of
one bundled and thirty feet to the mile. |
From that point the railroad runs on the |
top of the hume, and the grade is such as |
to require the use OF horses in hauling |
ore to the mill. When there the cars are |
lifted by machinery connected with the |
waterwheel, tifty-two feet high, up an in
cline and dumped upon iron CRATES that |
let the fine ore pass through, and carries !
the larger pieces to the rock breaker,
where they are broken tit for the stamps. |
This large mill has demonstrated the fact |
that large mills if properly constructed are
more profitable than smaller ones, and
that the cost of working the same num-
Der of tons of ore in this is not much !
over half the cost in a five or ten stamp |
mill This valuable property is owned |
by the Union Mill Company, and since it |
started last March, has been constantly |
doing splendid work; giving perfect salts |
faction to the owners. Mr.. King Is the |
who has made this mill |
do the work Mr.. Fountain intended it |
should do. He has the, reputation Of be- !
ing the best mill Superintendent in Ne
vada, and was chosen for this place for |
that reason, and his success speaks for |
itself and justiies the opinion.
