in doubt as to whether the population served is sufficiently large to warrant 

 the capital expenditure. 



Now, this was in 1914, and I presume Sanderson & Porter based 

 their opinion on the per capita use of hydroelectric power in the 

 United States, which works out at 0.10 horsepower per inhabitant, 

 according to the textbooks. 



Since then, however, newer data have come to my hand, and if 

 these data are accurate, as I presume they are, the complexion of 

 affairs has changed and the Hopewell plant is a really good com- 

 mercial proposition at the present time and needs only the govern- 

 mental help accorded by a good charter. 



The data that I speak of were published in Saturday Night about 

 February, 1919, and are contained in a very interesting table 

 which shows the per capita use of hydroelectric power for every 

 Province of Canada and for the Dominion as a whole. It shows that 

 British Columbia uses 0.36 horsepower per capita; Ontario, 0.288; 

 Quebec, 0.267; and the whole of Canada, 0.206, and these figures are 

 for the total population, and they should be increased at least 30 per 

 cent for the per capita use of population served. It will thus be 

 seen that Ontario, per capita served, is using about 0.37 and Quebec 

 about 0.35, and I think we may properly assume that 0.36 would be 

 used by the inhabitant of the Maritime Provinces as soon as you 

 could give him really cheap electricity. 3 



On this basis, then, the population of 250,000 would require 90,000 

 gross horsepower, or, say, 45,000 horsepower at the delivery points : 

 and I think the initial development at Hopewell should be for 90,000 

 horsepower, 4 with every provision made for increasing the output 

 as already outlined in this paper up to 200,000 gross horsepower, as 

 the population and demand increased, as they undoubtedly would 

 when cheap power was available. 



COSTS 



We now turn to the question of costs, and I have made an estimate 

 of this as follows and in accordance with the textbooks on the 

 subject: 



Dam cost in Cyclopean concrete 

 Western dam : 



730 lineal feet, at equivalent height of 38 feet and $210 per 



lineal foot $153, 000 



4,100 lineal feet, at equivalent height of 65 feet and $480 per 



lineal foot 1, 965, 000 



3 The latest data show that since tills was written (1919) the per capita use in 

 Canada of hydropower has increased 22% per cent and it is steadily increasing. 



4 Probably now 110,000 horsepower in view of the above noted increase in per capita 

 use.
