VIRGINIA CITY, New, Dec. 10-Appended Will
be found the official letters of superintendents OF
operations In the Comstock mines:
Con. CAL. & YA.-11oo evel-The west
crosscut from the main north lateral drift 315
feet north from the shaft station, has been ad-
yaneed Is feet. total length 4S4 feet; face In
pOrphyry and low-grade quartz of nominal
value. 1900 level-From the south drift at
the point of connection win the old slopes
We continue TO extract some ore and filings
Of average milling value. 1900 leyei-We
The old sill floor of The old slopes. from
which some ore OF fair quality Is being ex-
tracted. 1860 level-Con.inued TO extract some
ore from the drift run east from wnZe down

some ore from the old stopes at the north end of
The California ground. From the crosscut run
west from tile northwest drift. we are running
north in the old slopes and extracting ore. 1850
leye-Hsve continued 10 extract some good
milling ore from the point where the up

south from the eUd OF the main southwest DRIFT
connects With the nlnth-toor openings. Are

Upraise-45 feet up-wtth the upraiSe "A feet
east. Have continued stopping out ore along the
drift run north from the crosscut run west from
the main southwest cFOsscut. The north drift
started from The old west erosScut. 80 feet north
from east croSScut >, from main southwest drift,
has been extended 2 feet; total length 46 feet.
Al this point are enlarging the drift and making
preparations To upraise Iherefrom. 1900 level
In Stopping upward from he drift run south from
the crOsscut run east from the bottom OF winze
2 down 40 feeO. have extracted some milling
ore. Owing to tile increase Of gas coming from
the 1900 ana 1850 level Old stoDes on The west
side OF the ledge and south OF the Con. Virginia
shaft, operations through the shaft, which is an
upcast or outlet for air. have been sus-
pendea for for the past few days: The gas
some years ago. and are not accessible
as all the drifts and openings have partially
closed from ground movement and heavy crush
Ing. There is undoubtedly fire in some part OF
these old slopes, caused by friction from the
ground crushing and breaking tile tlmbers. All
drifts and openings leading 10 the points where
the gas escapes on the 1850 level being
closed. leaving small opening for the escape OF
gas up through the Consolidated Virginia shaft.
On the 100 level work has been SUSPENDED.
On the 800 level we have resumed work In the
Slopes. sending the ore through au upraise north
from the shaft 10 the 1850 level, then to
Ihe surface through the Con. Cal. snaft.
There has been extracted from all parts of the
mine during the week SS31490 1000 tons OF ore,
which was shipped 10 the Morgan mill, the aver
age value OF which per car samples was S23 68
per ton. The average assay value Of all the ore
worked at that mill during The week (9S0 tons
was $50 63 per ton per battery samples. Bullion
shipped TO the Carson mint had an assay value
of SIT ,904 Is.
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 lol feet below
the sill floor OF this level has been carried up
eight feet total height thirty feet, continuing in
porphyry and quartz OF very low assay value.
Bullion shipped TO Carson miEt assay value
MEXICAN-On the 1865 level the dfift run
north from the crosseut run east from the bottom
OF the winZe sunk 101 feet below the sill floor OF
this level, near the south line OF the mine, has
been advanced twenty-five feet. total length 373
feet, continuing In a porphyry formation with
lines OF lOw-grade quartz.
UNION CoN.-At the 900 level the Joint Union

tended during the week 20 feet; total length
west from the joint shaft 2ToS feet; the face in
porphyry. Sierra Nevada west crosscut from
