and lower tools and timbers, as well as
hoist orc, II r. not easy to estimate the
ore production they can handle. but It will
be q material increase on what has been
possible with the old machinery.
The two mines. which are being operated
Jointly by separate companies both con-
frolled by the 0oodenham- Black stock
syndicate. now have several compressors
with q combined capacity Of between fifty
and slxty drills, part Of which r. being used
to run diamond drills the mine pumps. also
the auxiliary hoist at the zo-focf level In
the War Eagle. A forty-drin compressor Il
being built for installation on the Center
star ground where the building and found
ations are now ready. This Will Increase
the capacity for the two mines to nearly
100 drills. alnncst tho whole of which VIII
become available when the auxiliary hoist
Of the War Eagle In done away with, as
viii shortly be the case.
Steam to operate all the machinery Of
both mines win be furnished by boiler
plant OF 1000 horse power. which has been
installed on the Center Star ground. with
an auxiliary plant Of 800 horse power In
the 9silch below. Steam IL conveyed up
the mountain to the War Eagle hoist by an
eight-inch pipe 1000 feet long. which II
inclosed In a wooden box four feet square.
Radiation OF heat II prevented by filling
this box with coal cinders, Afted fine. and
the pipe Is also protected from water by a
train underneath. In connection with the
nav compressor a tower about forty feet
high II being erected to cool the circulat-
ing water for condensing. a measure of
economy very necessary In the dry season.
All the pumps. compreesers and boilers
are 70 arranged that they can do service
for either mine.
Grading ts In progress for timber-fram-
ing building which win be annexed 10 tho
Center Star hoist house and will he equip
ped with framing machine and all tho
necessary eaws. Plans are also In course
of preparation for an ore-crushing and
sorting plant for each mine.
The new hoist. compressor and buildings
