horsepower and, later on, 4725OO
horsepower Recognizing the prospective greater
demands for electricity in the course of the next
few years, the projects discussed in the current
issue are of timely interest. In the order of their
preference, they are first, dam few miles be-
low the Falls which will make use of the full flow
of the river, and second, an installation at Goat
Island which, of necessity, would have to absorb
waters that might diminish the impressiveness of
the present Falls.
So says the editor of the Scientific American in
an editorial note article in the Scientific
American with the title Making the Most of Nj
Ggara.' Robert c. Skerrett furnishes both the
text and the diagrams herewith reproduced.
AS everybody knows, Niagara Falls is a natural
wonder of beauty and power over which the ma
ture lovers and the commercial interests have
been fighting for years The article follows:
The Niagara river will inevitably be utilized
more extensively than now for the development
of hydrO-electric energy. The rush of those de.
scending waters must be put to greater practical
service wherever feasible without seriously impair
ing the scenic beauty of the Falls. Upon both
of the governments concerned the people are max
ing insistent demands for bigger blocks of power
and the authorities are listening sympathetically
because of the logical promise of vast savings
through the corresponding nOn-use of coal No
fewer than ten projects for water rights on the
Niagara river have been filed with the United
States federal power commission, and among them
are two that are sufficiently matured to warran.

Both Of these contemplated hyro-electric propo-
sitions may well be considered as a single CO.
Ordinated system, for they have been conceived
and espOused by the same men, /. e., T. Kennard
Thomson, c. E., of New York CITY, and Peter a.
Porter, of Niagara Falls The dual project en-

massive foundation of Goat Island so that water
may be led through them to large turbo-gener-

citizens of this country would benefit by both of
these engineering undertakings.
According to the existing treaty arrangement
between the neighboring countries 1t Is not now
permissible to divert for power purposes above
Niagara Falls more than $4,000 cubic feet of wa
ter a second; and for certain reasons the Ameri-
can allotment of this is 10000 cubic feet. 1t has
been proposed that the combined total be raised
to $4,000 cubic feet, and thet each of the nations
share equally. In other words Canada would
have 1900 cubic feet more than Is the case TO-DAY

fact that 1t is an integral part of the massive
ledge there underlying the river, and this has
very important bearing upon power development
at that point. From the crest to the base Of the
Horseshoe falls is drop of about 1876 feet, but
the plan is to Increase this head to substantially
200 feet by frightening Goat island. From east
to west, along its major axis, the island is today
$500 feet long, but there is nothing to prevent
extending 1t 600 feet by raising abQye the surface
Of the river the slightly submerged area at the
upstream end.
BY doing this it would then be practicable to
drive the tunnels from water level to water level
at a moderate angle and so insure difference in
drop of about 200 feet between the intake and
the discharge ports of the conduits. At the same
time. the bores in their entirety could be cut
through solid rock. Each aqueduct, when finished
with a concrete lining. would have an internal
diameter Of 20 feet and the descending waters led
by IT would be capable of developing 100000 horse
mower through the medium Of suitable turbo-gen-
orators. AS now projected, only two tunnels would

horsepower but the physical conditions Will Ill
