are repairing the main rough drift and
the east crosSeut leading therefrom to the
upraise connection with the north drift on
the 1900 level 1860 leyel-We have cOntin-
ued making necessary repairs to the drifts
or the sill floor of this level. We continue
to extract some ore from the old slopes
eight floors up 10 the upraise, No. g. carried
uD from the old slopes in working north
from the crOsscut run west from the north
west drift The drift run west from these
north workings, 81 feet up the upraise, started
so feet in from the mouth OF the drift, has
been carried up II feet, total height 80 feet,
the top being in quartz formation carry
ing a low assay value. We have continued
to stOpe out ore Of fair quality in working
the north and south sides of the drift run
east (tt a point twenty feet down from the
Wine which was sunk from the croSscut
run west from The main northwest drift
We have extracted during the week from
all parts of the nine CAT cars OF ore, making
about $40 tons. Shipped TO the Morgan mill
6J8 lO30-20O0 tons of ore. Average assay

HALE 81 NoRCRoss-In the main shaft
we have finished easing the timbeTs between
the 900 and 1100 levels. Main inclIne-We
continue 10 make the necessary re;airS. 1880
leYel-We have advanced the west crosScut
on our south boundary % feet; total length
