to it the right to develop on the Canadian side at least 250,000 

 horsepower, but this has been modified and in 1904 additional 

 developments are in process on the Canadian side by the Ontario 

 Power Company and the "Electrical Development Company of 

 Ontario. The Canadian Niagara Power Company proposes to 

 limit its development to 110,000 horsepower while the Ontario 

 Power Company will develop 180,000 horsepower. The Develop- 

 ment Company of Ontario has a capacity of 125,000 horsepower. 

 The total possible power which may be developed in the future 

 at Niagara Falls is about as follows: 1 



Horsepower 



Niagara Falls Power Company's present tunnel 100,000 



Niagara Falls Power Company's second tunnel 100.000 



Niagara Falls Hydraulic Power & Manufacturing Com- 

 pany's canal 150.000 



Canadian Niagara Power Company's t unnels 110,000 



Ontario Power Company 180,000 



Development Company of Ontario 125,000 



Total 765.000 



The developments in progress at Niagara Falls are being car- 

 ried out on very broad lines and probably furnish the best exam- 

 ples of modern hydraulic work. They certainly lead so far as the 

 United States and Canada are concerned. A complete account 

 of the works, giving details of all the engineering features, 

 would make a large-sized monograph. 2 



1 For an interesting discussion as to the effect of diverting large quantities 

 of water from Niagara river for power purposes, see report of Clemens 

 Herschel, made December 12, 1S9.">. on the Diversion of Water from the 

 Niagara River for Power Purposes by the Niagara Falls Hydraulic Power 

 and Manufacturing Company and by the Niagara Falls Power Company, 

 and the Unimportant Effect of such Diversion upon the River. Mr. Her- 

 schel bases his discussion on the data of the lake survey of an ordinary and 

 usual flow of 200.000 cubic feet per second. Reasoning from this premise 

 he concludes that even when 300.000 or 100.000 horsepower are in use the 

 effed upon the depth of the river will be insignificant, it seems clear 

 enough that this proposition is open to discussion. 



The main facts in regard to the plant of Niagara Falls Power Company 

 have been furnished by L. H. Groat, former secretary of the company. For 

 more extended information the reader is referred to 1) Cassier's Magazine.
