IMPROVEMENT WORK UNDER
WAY At CALUMET & ARIZONA
CONCRETE rs TO REPLACE TIM.
Der IN JUNCTION SHAFT
OF PROPERTY.

Preparations are under way by the
Calumet and Arizona company Tor
project of Importance and magnitude
that is of considerable interest To the
district. says the Bisbee Review. This
is the replacing of the timbering in the
Junction shaft of that company with
concrete The preparations thus fan
for this work have consisted in tho
making Of molds but actual work Is
expected TO be started within the next
few days. It is learned that this con
crete work will be done 10y the COM
parry ana not under contract as there
has beer heard some talk that IN
would be- Don RAFT is TO be IN charge
of the work under w. L. Mckee and it
Is expected that a force of at least
thirty men will be given employment
from nine 10 ten months, that being
The estimated time for completion.
Since the Junction is a Ave COM
partmcnt shaft 1890 feet In depth ant
the concrete work will extend down
TO the 1900 level some magnitude of
the undertaking may be formed. The
concrete Will take up less space than
does the present timberins and in the
end win prove an economical meas-
ure. IL is the first experiment of tn.
kind to be attempted in the camp anl
may mark the beginning of such work
in all of tho shafts, or at least many of
them so 1t will be- watched with inter
est by all In putting in the concrete
the molds will be placed In position |
below while all material will DO mixed |
ON the surface. This concrete mix
ture will be pipcd down into the molds |
at the lower levels thus avoiding the |
working of so many men in the shaft |
as to crowd one another There are
TO be three shifts employed each day |
Beyond the announcement of the |
starting of this work at the Junction |
there is nothing out of the ordinary |
reported by G. ~ \. officials as to the |
mines Development and production |
work both go on as usual. The prod
uctiou keeps up with the normal and |
the development work is largely in the
Briggs ana cole countries with con-
tinuance OF the same excellent results
and the blocking QUO of large ore bod
ies that continue TO extend the known
values of the bonanza properties.
