STEVENS.
All examination of the Stevens mine shows
this excellent mining property to be in supe-
rior shape at the close of the week. The east
level from the main shaft has been advanced
a distance Of 1872 feet, running on the foot
wall and following the vein all the way, thus
opening the vein, which is in places fully sew
en- feet wide, pretty tho oughly. This level
starts from the main shaft at a depth of 100
feet and as it advances east gains greater
depth from the surface. At ITO feet in this
level, from the shaft, a cross-cut has been run
from the foot Nall to strike the vein on the
hanging wall, or in other words to strike the
parallel vein of the mine. This We n has
been ST. uck, and yesterday the drift had been
put into the vein two feet. An assay of the
ore hrst struck, showed fifty-three ounces to
the ton in silver, with the ore improving i'll
looks as the drift nears the hanging wall.
Iu the end of the level advancing east the
ore-vein is enlarging, and an assay of the ore
coming out showed 1S9 ounces of silver to
the ton. The new steam hosting and pump
ing machinery for the Stevens mining com
pany has been ordered from the Pacific
Works, San Francisco, and is expected to
arrive shortly. This new machinery, of a
similar pattern to that now in successful oper-
alton at the Anselmo mine, will be placed in
position at the middle shaft of the mine.
The vein of the mine at the middle shaft is
very strong and of a high grade. This new
machinery is Of sufficient power to work the
mine to a depth OF seven hundred feet, and
will be erected with the greatest dispatch
possible on its arrival.
ANsELMo.
The main shaft OF the Anselmo mine,
which is about eighty feet from the west
boundary of the claim, has reached adrpthof
265 feet on the incline Of the vein. la the
bottom of the shaft the ore vein is widening,
with unmistakable evidence of increasing in
thickness. The ore lifted is full of fine par
ticles of silver, and pretty thoroughly impreg-
mated with black sulphurets. The level be-
ing driven cast from this shaft is in about
fifty feet on the vein, which is yielding Gre of
an exceedingly rich claracter-'he ore on the
dump being very nearly all Of that quality in
which native silver is easily seen. As the
| shaft drops downward no perccptible ~inerease
in the head of water is manifested, the pump
handling the water easily without being at
work half of the time. At the old shaft to
the east the new steam hosting machinery
was in active motion yesterday, draining that
portion of the mine by means of an ron
bound barrel, which was lowered and raised
very rapidly. About twenty feet of water
had flied in the shaft and levels during the
suspension of work caused by putting up the
new machinery. Within a day o. SO the
water will be out aud the work of level run
ing to the east and west will be vigorously
resumed, besides the work of Stopping in the
levels. The new double machinery now Ill
use at the Anselmo mine will enable Mr..
Lacatf, lessee of the mine, to extract thous-
ands of tons of first-class ore before the lease
expires.
MORNING TAR
In order to sink the main shaft deeper ana
provide against the necessary increase of
water in the Morning Star mine,a new No. u
Knowles pump has just been ordered tor the
mine and is now on the way. The present
machinery is able to contend with the volume
Of water now to pump, but cannot stand the
pressure of an increase. Work at the main
shaft OF ,he mine goes ahead with the usual
energy displayed at this mine. The ore TAX
en- from the slope in the east level, about
thirty feet from the shaft, shows ID ounces in
silver, besides considerable gold, to the ton.
The west level had been pushed forward yes
terlay to a distance of l03 feet from the
shaft, and is about under the sidewalk on
| Montana street. The end of this level is in u
tine vein Of ore, al assay of which showed 221
ounces in silver per ton, and $50 in gold.
The ore hoisted from this level, and the
slopes therein, is uniformly of a good quality,
and the assays made daily show a high aver
age. The ore-product of the Morning Star
for twenty-five days during the month Of
April was 220 tots, which was a fraction over
nine tons per day. This can be readily in
erased when the levels are heightened. In
the west shaft the vein is looking better and
growing thicker. This shaft, on which Il
hand windlass is still used is down 100 feet.
An assay from the ore in the bottom Of the
shaft yesterday showed l16 ounces of silver
to the ton.
MOUNT MORIAH.
The Mount Moriah mine is being opened
in a thorough manner. Level running both
ways from the main shaft continues. The
west level is in from the main shaft 40 feet.
This level is following the vein, and is now
running in a vein of four feet M width of
high grade ore, with two shifts of miners
pushing it ahead. The east level has been
driven forward 100 feet, and Is daily advanc-
ed eastward with two shifts employed. In
