Industrial Niagara 



generator with its wheel must be about equal to the head of 19 * )S 

 water, and that the weight and cost of the shaft and of its sup- 

 ports must be correspondingly great. 



For these reasons, the plants now under construction about 

 Niagara Falls have either their generators and wheels in pits as 

 close as possible to the falls, so as to reduce the amount of 

 excavation in both pits and tunnels, or else have them located 

 in the gorge or at the foot of the escarpment and supplied with 

 water through a canal or pipe line. For future plants designed 

 to develop power with water from the upper river, canals or pipe 

 lines are quite certain to have the preference.

A discussion of power development in progress on the Canadian side, 

 taking up the problems presented, the difficulties to be met, the engineering 

 features of the various constructions, the uses of the power developed, and 

 the effects of diversion. The author thinks that " the real danger to the 

 falls will come from the granting of additional franchises in the future."
