full bibliography of 30 pages, and appendices giving, among other 

 things, the text of the laws concerning the export of power and 

 also of the treaty recently concluded with the United States re- 

 garding the establishment of an International Joint Commission. 



The volume opens with two chapters of an introductory nature 

 that are concerned mainly with the general economic bearing of 

 waterpowers on national development. The relation of water to 

 agriculture, mining, navigation, domestic supply and so forth, 

 is dealt with, and the principles to be used in the interpretation of 

 waterjx)wers data are stated and discussed critically. The broad 

 and optimistic statements very often made on the platform and 

 in the press regarding our vast waterpower resources are de- 

 precated. 



A chapter is devoted to the waterpowers of each province in 

 which the general features of the province as regards waterpower 

 development are discussed, and an outline given of the law where- 

 by powers are granted or leased to private individuals or cor- 

 porations. The larger developments are also described. The 

 statistical data given in tabular form includes the height of the 

 fall, the horsepower that may be developed, the present develop- 

 ment and the main uses to which the power is applied, such as 

 lighting, pulp and paper making, etc. Reference is also made 

 to the possibility of increasing the amount of power developed 

 by storage reservoirs and dams where such are feasible. 



The power situation in Ontario is treated very fully, special at- 

 tention being given to the power possibilities at Niagara and the 

 conditions affecting development there. The report states that 

 the low-water flow of the Niagara River would yield at the Falls, 

 about 2,250,000 horsepower, of which Canada's share (one-half), 

 would be 1,125,000 horsepower. Franchises have already been 

 granted and plants partially completed, for the development on 

 the Canadian side of the river, of about 450,000 horsepower. In 

 other words, instead of "millions" of horsepower being available, 

 as has been sometimes stated, it appears that about half, and by 

 all odds the better half of Canada's usable share of Niagara Falls 

 power has already been placed under private control. 



The volume embodies all the useful information regarding 

 the waterpowers of Canada that has heretofore been collected, 

 and this has been supplemented and, in many cases, verified, by
