THE COSMOPOLITAN NINE.
Present Status Of Development.

before given very elaborate notice
of the discovery, working and devel-
opment of the mine, and can now

GAN EXTENSION"
On the previous notes. The total
length of the main tunnel is now 500
feet, the face of which is 200 feet
from the surface, between good solid
we'll defined walls, and into quartz
which gives fair prospect, though
not as rich as some that has been en-
cOuntcred.
ABOVE THE TUNNEL
For $50 feet, after striking the vein,
the quartz has been stopped out and
millcd in the Hope mill, to distance
of from so feet to the surface of the
lead. The rock from the slopes has
all paid handsome profit, and is in
extent and quality sufficient to give
the best of encouragement for deeper
development. About 80 feet from
THE FACE OF THE TUNNEL
A Wine has been put down and well
timbcrcd on the vein to a distance OF
IS feet, and is now in ore of dark
brown color, intermiXed with yellow
quartz, blush clay and occasionally
stringers of gypsum. The gypsum
is gradually but surely working out
of the vein matter as the depth is in
creased, and from present indications
will soon disappear altogether. AT
this depth the vein is about four feet
wide and is very much broken up,
though the foot and hanging walls
are as perfect as at the top OF the
Wine, and that means
PERFECTION ITSELF.
Work in Tie Wine as also in the face
of the tunnel, is being rapidly pushed
ahead by Mr.. Brannan, the foreman,
who. by the way, is not only thor
oughly posted quartz miner, but also
a courteous and polished gentleman.
With change of officers would most
naturally come a change in the sys-
TEN of development, each well posted
man having his own peculiar views
about the course of development to
be pursued. From an inspection of
the previous workings of the mine
and comparison of them with the line
of development now pursued, we can
only say that we coincide fully with
the expressed judgment Of Superin-
tcndent Eagan, us to the system
adopted. The sinking of the Wine
alluded to is to be continued steadily
until the arrival and arr ,ngcmcnt OF

can be calculated, 300 feet from the
surface. In raising the Wine it will
pass through pay ore for nearly, il
not quite, the entire distance, and

ADEIFT
Is now being run into the present
working drift to tap it 20 feet from
the face. This drift will be for the
purpose of vcntilating the mine, and
will afford all of the air necessary fol
comfort for some time to come. The
ore from the Cosmopolitan, is mostly
productive of gold, the production OF
silver being onc-fourth or one-fifth
as is well known, and has been
crushed at the Hope mill with an av-
cragc result of about $50 per ton
The mill Is now shut down, it being
deemed advisable and of much more
importance to rapidly develop tho
mine than to devote the time to the

From the slopes. In many places

75-foot Wine, as also in driving the
face of the tunnel, rich, dark-coored

which give reasonable hope of crowd
ing out the gypsum and barren rock
at deeper prospect. We regard the
appearance of the formation in the
bottom of the winzc as highly favor.
