WHEN Doctor,, Differ, Etc.

The opinions which have been ex-
pressed by professors, experts, and SCI
entiic men generally, respecting the
| character and permanency Of the veins
of the Reese River District, especially
those of Lander Hill, are as numerous
and varying as the hills which hold
them. With some the rock is too new,
with others it is too old, and a third
class Of philosophers it is sort of be-
twi1t and between, and, do you see, it
canuot be the bearer Of, permanent sill
yer veins. In our poor judgment it is q
good plan to take the silver in whatever
shape or place it may be found, and let
the rocks take care of themselves. One
distinguished professor writes thus Of
the permanency Of these mines: 1.-THE
incasing rock in the Reese River Dis
trict is granite and quartzose, both Of
which are of the azoic age Of rocks. and
of the class in which metalliferous veins
are most likely to be found. The veins
through Nevada are declared to be true
assure veins, and reach to indefinite
depths in the bowels Of the earth. These
may be mined o. far as the ingenuity Of
man can devise means for extracting the
ore, at a cost not exceeding the product.
Their practical ineIhaustibility is.ex-
empli6ed by the tin mines of Cornwall.
These were known to have been worked
in the time Of Solomon. from these
came the tin that formed the bronze
that ornamented the Temple. For thou
sands Of years the exhaustion has been
going on, and although the Duchy Of
Cornwall, from which so vast an amount
of metal has been taken, is not half as
large as Lander county, still it produces
as great quantities IS ever, and new
veins are often found of as great value
as those that have been worked for CEN
turtles.
The veins of Cornwall are thin, and
in granite, as are those of Austin. If
they have lasted so many thousands of
years, and turned out such great
amounts of metal, why should not thesef
We cannot count upon the time, when
mining will cease to be profitable in
these hills" Another skillful engineer
and metallurgist gives the following

figures are at all correct, it is 4 matter
of little moment whether the mines will
be productive to a great depth. A small
vein that will produce $40, 200 900 or
$l2, 900, 900 Of silver at a perpendicular
depth Of less than 200 feet, may be
reasonably regarded Is permanent.
But to the glowing figures. |
"My first estimate Is Of the amount Of
ore above your present levels. You are
down on your vein l2o feet, and l take
as the minimum average Of the thick
ness of the pay matter in your veln'two
feet, and as the minimum net yield of
your ore over and above the cost of
milling $3.50 per ton. Six hundred feet
in -FOUR claim, 100 feet Of vein, with two
feet of pay matter, gives $4,000 cubic
feet. Ten cubic feet in place make a
ton; this gives l4,400 tons of ore; at
$3.50 per ton net, gives q net yield Of
So, 5000, 900. My second estimate'is Of
the amount Of ore belop your present
levels, and down to the level of the tun-
mel which / propose you run in your
vein. The tunnel will strike the vein
at a perpendicular depth Of 1874 feet,
making an incline depth of 220 feet.
Tho same calculation as above will show
a result Of $4,000 tons Of pay ore; at
$3.50 per ton net, gives a yield Q f$6,6oo,-
600. This 10 the amount.o of pay ore
in your vein, that can, DO got
