Superintendent Richard says: I beg to
hand you my report Of the different opera
tons for the past week. The 200 westerly
drift has been advanced three feet; ground
hard. The 200 northwest drift has been
extended IS feet, without any change to
mention. The winze from end of 200
main drift has been sunk nine feet; now
down a total depth Of 81 feet; the ore in
the bottom is narrow. A drift has been
started from the bottom of the winze.
drifting easterly in good ore. The 400
north from No. Is chamber has been ad-
vanced 10 feet; the present end is in hard
limestone. The 400 north from No. 8
chamber has been drifted II feet, without
any change to mention. The 400 north
from No. IL chamber has been extended IS
feet, in very favorable looking ground for
ore. The 500 north from No. IL chamber
has been drifted six feet; the present end is
in favorable ground. The 600 west drift
has been advanced six feet in hard ground.
The 500 No. l cross-cut west from south
fissure has been extended II feet; the
ground is more favorable for drifting.
The 600 No. 2 cross-cut west has been ad-
vanced 10 feet in hard ground. There is
no change to mention in either of the
wines sinking below the 600. The 800
west has been extended nine feet in hard
limestone. There is no change to Mention
in either Of the 900 drifts. All the chambers
are opening well, and turning out the
usual amount Of good grade ore.

Superintendent Potter reports as fol-
lows: Work has been carried on in the mine
during the week with most satisfactory re-
suits, and a steady improvement on the
ore reserves as prospecting is carried on.
The east winze has been pushed down since
my last report Through a solid body Of
ore) a distance OF 6 feet, making a total
depth Of SO feet. The probability Of this
ore body proving itself to be permanent is
more favorable than at my last writing, II
that Is possible. About 40 tons of ore
have been taken out OF these workings
during the week, the majority of which 10

has been run O distance OF 8 feet, follow

The local management furnishes this in
formation The winze from the 400 to
the 500 foot lsvel has gone down IS feet
now down 90 feet still in good ore. At
the south end Of the ore body we have
been rising this week, and got up 20 feet
still in ore, but somewhat smaller. There
is considerable improvement in the ore
body at the $50 foot level only two men

in 66 feet. We have struck q small body Of
ore, which is undoubtedly a continuation
of the ore body found In the 400 foot level,
but not sufficiently developed to enable me
to form any opinion as to its extent, but it
looks very favorable. At present we are
shipping about 10 tons per day
