The only other important opening is
the working shaft, which is an incline
500 feet deep, equipped with a gasoline
hoist, skip, etc. The driving of this
shaft to such depth before further ex-
ploring the vein was done to develop
a water supply for hitherto the mine
had been a dry one, water being hauled
even for camp purposes. Water was
first found at $50 feet, but sinking con-
tinued to 500 feet, when cross cuts
made north and south for the dual
purpose OF determining the nature and
width of the vein. the cross cuts to be
used later as reservoirs while ore was
being taken from upper levels. The
cross cut to the north was run 100 feet
through two thin granite strata the
rest OF the distance being solid diorite
or black rock carrying values of about
SO to the ton. The level had to be de-
serted on account of the water before
the wall was reached in either di-
rection. The cross cut to the south
was through 80 feet of granite, then
