will be found the official letters of superiu-
tendents of operations in the Comstock
mines:
Cox. CAL 4 VA.-1100 level-Tne old
crosscut from the south drift 80 feet south
from the shaft station has been extended
10 feet; total length reopened 60 feet A
drain has been placed at the mouth Of this
crosscut and water let in through pipe in
the dam is now running along the crosseut
to the old stope timber. The main south
drift has been reopened to the sill floor
slopes and we are closing the Wine con-
nection with the 1850 level by filling it
with waste rock to shut off the heated air
and gas which come up from that level. After
doing some necessary work at this point we
will be prepared to resume the work of ex-
tracing ore for these slopes. There has
been gradual decrease during the week of
gas escaping through The Con. Va. shaft.
1000 level-We are repairing the main south
drift aud the east crosscut leading there
from to the upralSe connection with the 1900
level, north drift 1850 level-We have con-
tinued making necessary repairs to the
drifts on the sill floors of this level. We
have extracted from the old slopes eight
floors up in upraiSe 6, carried up from
the main northwest drift. and raised TO the
surface forty-four tous of ore OF an average
car assay value of $50 10 per ton.
OPHIR-1465 level-The upraise started
on the sill floor on the north side of the
crosscut run east from the drift run south
from the Mexican into the Ophir ground.
10l feet below the sill floor of this level, has
been carried IA feet, total height.'66 feet
continuing in porphyrY with quartz
MEXIcAN-On the 1866 level the drift run
north from the bottom of the Wine sunk
10l feet below the sill floor of this level
No n IA
advanced Is feet. total length 443 feet, con-
tinuing in porphyry and clay. showing lines
of quartz.
UNION CoN-900 leyel-The joint Union
Con. and Sierra Nevada west drift has been
extended during the week % feet; total
length west from the joint shaft 2795 feet
The face is in porphyry with small streaks
OF clay from which there is a strong flow of
water.
SIERRA NEvADA-West crosscut from
kenosha tunnel started from the north drift
500 feet in has been advanced 80 feet; total
length 566 feet; face in soft porphyry with
stringers of quartz and clay. The joint
Sierra Nevada and Union west drift, 900
level. has been advanced &c feet; total dis
lance west of shaft 2795 feet; face in por-
pbyry with small seams of clay from which
there is q strong flow of water.
CHoLLAR-The north drift from the south
line $50 level is out IS feet. The face con-
tinues in quartz which gives fair assays
Two compartments in the main shaft have
been retimbered for 10 feet above the $50
level. The north drift from the east cross
cut 100 feet south of the north line $50 level
is out II feet following clay wall on the
west side of which there are punches OF
quartz which yield fair assays.
POTOSI-The east croSscut from the PotOsl
Wine station, 1000 level. has been connected
with the west crosscut from the top of the
raise from the HOO level. giving US good ven
sIx&sZ A-sf I'd In
southeast corner of the raise, which Is now
out feet, face in porphyry. Extracted and
sent to the mill during the past week 3l6
tons and 1900 rounds of ore from the 900,
900 and 1150 levels; milled during the week
800 tons; on hand at mill, IS tons and 1850
pounds average battery assays, S25 40;
average car sample assays. S31 10; shipped
TO Carson mint, $50 pounds OF crude bullion.
BULIIoN-The EAST croSscut 100 feet north
of the top of the raise from the east cross
cut 800 feet south of the north line, 1900
level, is out % feet; the face is in quartz
northwest drift 800 feet south of the north
line 1900 level of the Ward shaft is out 125
feet; face In quartz yielding low assays.
ALPHA--The joint Alpha and ExcheQuer
east crosscut on the north line of Alpha,
1900 level of the Ward shaft, Is out 1870 feet;
face in porphyry. Heretofore We have been
running the blower with compressed air.
which has been expensive. We are now
putting in water-eolumn in the Ward
shaft 10 enable us to run the blower with
Pelton wheel.
ExcHEoUER--Tn joint Alpha and Ex-
cheQuer east crosscut ON the north line OF

feet; face in p0rphyry.
