ever, to the outbreak of the Civil War,
further operations ceased, and for years the
stream flowed over the cliff unused. In 1877
the Hydraulic Power and Manufacturing Com-
pany was formed, purchased the canal, and
began the construction of a mill equipped to
give 900 horse-power under a 50 feet head
of water. The iron flumes, 9 feet in diameter,
carrying water to the wheels, were the first
iron penstocks to be used at Niagara. The
head on the mill was eventually increased to
86 feet, the highest up to that time utilized
in the district.
With the construction, in 1881, of its first
hydro-electric station, the same company
opened a new epoch in the history of industrial
development, and showed the world how to
use large volumes of high-pressure water.
Pits were sunk in the rock near the edge of
the cliff to depths varying from 25 to 86 feet,
and at the bottoms were placed turbines with
vertical shafts for bringing the pcnyer to the sur-
face of the ground, the “dead” water being dis-
charged through tunnels into the gorge below.
Within a few years, however, such rapid pro-
gress was made in the methods applied to the
development of power under high heads that
this enterprise was dwarfed to comparative
insignificance by the side of the larger opera-
tions initiated by the same company and
other corporations.
In the map printed on page 296 are shown
positions occupied by the generating
stations, etc., of the principal power-
supply companies on the Canadian and
American sides, taking water directly
from the Niagara River. These under-
takings, it should be clearly understood,
however, only partially represent the
present stage of development of power
production in the Niagara region.
Although, of course, each of the great
plants has distinctive features, hydraulic
or electrical, all are based upon fixed
principles. These are :—An upper level,
