of the mine where it is needed. The
hoist at the b shaft and at the Grey
shaft will be equipped for electrical
operation as soon a. the necessary
equipment can be secured.
Eventually wires will be run from
the power house To the Buckeye anu

Dominion lands proper. These parts
OF the Old Dominion property will
thus be worked by means of electric
power when all arrangements there

large steam pump on the 1,200-foot
level. The smaller pumps, located in
the various parts of the mine, will
pump the water into the large stump
prepared for il on the twelfth level,
and from this stump. the large steam
pump will raise the water to the
tunnel through which it will flow to
the surface.
