the new and complete steam plant of
the Grand Central mine is practically

appointed surface buildings nearly
completed. If the new plant of the
Grand Central does not surpass AL
others in UIan in point OF power and
capacity, it unquestionably leads IN en-
bodying the latest devices in safety and

against loss of life and property
through accident and fire.

The gallows-frame, which is fifty feet
to center of sheaves, is also built OF
structural steel, and rests on piers OF
solid masonry. The building and gal
lows-frame were designed and erected

one tubular feed water heater and one
Knowles boiler feed pump.
The power-house contains double

ing engine, equipped with the
most approved steam brakes, Lanes
steam clutch and steam reverse gear.
The rope reels have a capacity of 200
feet of fiat wire rope. The engine, DC

required to a depth of 1000 feet, was

The pumping plant now being in
stalled at Robinson will supply the
mine with water. and when all of the
new plants are doing their respective
duties, attention will be directed to-

which will convey the ore from the
mine to the railway
The magnificent plant reflects much
credit on the management judgment
and liberality, and in providing so COM

be able to make an output commensur-
