creased to 14 feet ; and with it has been
connected a fore-bay, 450 feet in length,
extending along the top of the cliff.
Station No. 2, 170 feet long by 100 feet
wide, is situated at the water’s edge in the
gorge, and is so designed that the water
can be used, under the full
available head of 210 feet, by
the turbines and generators
mounted on horizontal shafts.
There are now in operation
Houses. in this power-house sixteen
turbines, with a combined ca-
pacity of 34,000 horse-power, most of them re-
ceiving their supply of water through 11 feet
steel penstocks. The electrical equipment is,
in the main, in the form of low potential
direct-current apparatus. For lighting, how-
ever, it includes one 2,200-volt alternating
current generator, and for power service two
11,000-volt alternators.
The latest station of the Hydraulic Power
Company is 500 feet long by 95 feet wide,
also built at the base of the cliff. Running

lengthwise through the building is a solid
concrete wall, separating the
water - wheel and generator-
rooms. The turbines, each
having a capacity of 10,000
horse-power, are of the hori-
zontal shaft type, and make
300 revolutions per minute. A
considerable percentage of the
power generated at this station
is supplied, in the form of
direct current at 625 volts, to
the new plant of the Alu-
minium Company of America,
situated at the top of the cliff,
and within 100 yards of the
power-house. For the us© of
other local consumers—the Hy-
draulic Power Company has no
