| carnage was done at the Quincy than
year ago. The most serious damage
was done in No. 2 shaft. In this
SMART hosting operations were sus-
pended for several years and at this
writing have been resumed at half
tonnage rates, so that No. is send
ing to the mill but 600 tons of rock
per day instead of 1000 tons as
formerly. 1t ought to be stated too
that this rock tonnage is coming from
the levels much nearer the surface
than those which were operated to
advantage before the air blasts broke
down so much rock and blocked the
shaft. At the present time the total
rock tonnage of the Quincy is being
maintained so that the mill is not
suffering from any lack of rock 10
handle. The 600 tons shortage of the
No. shaft is coming from the Mes
nard shaft Al the worst. the rock
shipments were not shut off by more
than 500 tons. and that was but for a
few days, so that the production of
the Quincy mine for the month of No
vember is not likely to show any ma
terlal falling off, despite the diff
culties under which work has con-
tinued. However it will require some
time and considerable expense to put
No. 2 SHAFT back in readiness for regu-
lar operations again. At first it was
supposed that the shaftway was
blocked for distance of 1900 feet
but an investigation shows that there
are but two bad places where the top
walls OF the shaft came down and
blocked the passage. The debris will
be cleaned away rapidly and repair
work started. AS to the origin of
these disturbances local mining and
scientific authorities disagree. The
blast theory is the most reasonable
one, explaining the earth tremors by
the theory that old worked out Slopes
levels and drifts cave in, forcing the
air pressure with such rapidity that
the earthquake effect is noted. Others
really earthquakes. local in origin, and
that the damage is done to the Quincy
mine because It is so deep and be-
cause ii has such large worked out
underground openings. 1t ought to
be explained, for the credit off the
of the mine that every
precaution to- avoid these
air blasts has been taken. Six years
ago the company quit taking out the
pillars and started i'm with the under
ground filling system. calculated to do
a great deal toward preventing air
blasts. The directors of the quincy
ut their meeting on Wednesday, de-
clared the regular dividend.
Lake Copper Company
Great things were expected from the
stampmiI test OF the copper rock from
the Lake mine and the expectations
were more than realized. These let
tiers have repeatedly asserted that no
new lode ever opened in the Michigan
district made such a spectacular show
ing as has the Lake lode. 1t has sur
passed the showing of the Baltic or the
when the first shafts were
started at these mines. And the most
thing about the Lake show
ing is the fact that it has never pinch
ed out with depth, as the majority of
the so-called experts expected II to
10. Tn fact the lower openings have
been richer than those nearer surface
and there has been substantial copper
evidence from the time the sod was
first turned. This mill test was con-
lucted at the Franklin. a total of 165
IONS and 1000 pounds were sent to the
nill. From this copper rock 1927
pounds of mineral were secured. 1t
S estimated that this mineral win re-
Inc IS per cent at least. The mineral
output is, therefore, at the rate of 80
pounds to the ton of rock. The Frank
