THE MINE.

r eight miles north of the smelters,
d and is up in the hills. There is
d little or nothing in the scenery to
s attract ones attention, but vast
S deal ia the mine itself What would
g ordinarily be considered a serious
Y obstacle to the working of the mine
a has proved decided advantage
q all the water used for culinary,
4 drinking, engine and other pur-
e poses alike, has to be hauled to the
. mine a distance of nearly eight
: miles. The good fortune in this
? consideration is explained in this
wise: AS q mine is worked deeper,
r the more difficulty is usually expe-
rienced in handling the water which,
, as it increases, has to be hoisted
greater distance to the surface;
when anything goes wrong with
! the pumps, or when a new stream
is reached, the mine iSoften flooded so
badly that work has to be suspended
! for longer or shorter periods as the
case may be; and if no damage is
worked to the timbers or in loosen
: ing the earth, vast deal is lost in
wasted time. 1t has been said of
the mines on the famous Comstock
lode that the owners would rather
have imported every drop of water
, they needed from Europe in ounce
walls than to handle the water that
the mines have loosened as they
sank lower. To lave brought it
, from Europe as described would
have been mere bagatelle, a pit
lance, compared with the colossal
fortunes that have been consumed
. in handling it as has had to be done.
!, However, it will be seen that the
+ absence of water in the Mammoth
will prove of the most incalculable
. value in an economic point of view.
Q Another peculiar feature may be
+ mentioned in this connection. Both
Z milling and smelling ores may be
r found side by side In the same level,
and almost intermingling. This is
!. due to the absense Of water. AS
q rule smelling ores, containing
as they do the baser metals,a ARE only
found below the water line of q
. mine. The water has tendency
~ to lexiVate-that is,With the chemi-
. Gals in the earth it acts as q solvent,
, and carries the baser metals In a
dissolved form down, leaving only
:. the nobler metals such as withstand
. the aqueous action, behind. The
= consequence is that milling ores are
? generally above, and the smelling
II generally below the water line. In
\ the Mammoth, there being no trace
u of water, the baser and n0bler met
e ais are closely associ ted.
At the mine there are at present
q employed about $50 men, who man
= age to take out between seventy-Rve
e to 100 tons of ore daily, more than
"a the mills are capable of Handling
Il but an extra output will be re-
l. quired when the other furnaces are
L in readiness for working. The
d mine is pronounced by the ablest Of
q experts to be true assure vein
d and patented and free from law
Is suits. 1t is opened up in an aggre'
j. gate Of several thousand linear feet
Of Of shafts, tunnels, levels, drifts
" etc., and has been entered at differ
# emit points, and a new tunnel is now
: being run in. Wherever new de-
velopments have been made, they
tend only to show the almost bound
less ore supply, and the great width
n of the vein, which is recorded a.
% ninety feet in width. A depth Of
10 go feet has been reached, aud {
n practical miner, who has had ex
~ rerience on the Comstock and mines
n all over the west, after getting tt
If the bottom of this mine, and exam
re lining the ore at a depth of 600 feet
IA declared that it looked a great dea
ID better there than at any point in thu
m niue, and he looked upon it as ont
II of the biggest things his eyes hac
Id ever opened upon. Wherever ;
at pick is struck or q development
ss prosecuted, new and surprising re
ar suits are noted. It is as useless a
q impossible to 90 into a detailed
o description of the mine, as /;
n, general idea for the intelligence 0
ar the public is all that sucl
a paper is expected to give. A
ed before stated, the output of tn
ne mine is now placed by Mr.. Johnson
an the foreman, at seventy-fve ton
