canal. The plan adopted was to widen the original channel at 

 one side to 70 feet, and make the new part 14 feet deep. This 

 work is cut entirely through rock, below the water line. The 

 enlargement of one side was completed in 1896. The canal as 

 enlarged to date has a capacity of about 3000 cubic feet per 

 second, giving under present conditions a total of from 40,000 to 

 50,000 horsepower, the cross-section being about 400 square feet. 



In a letter from John Harper, engineer of the company, written 

 under date of .May 24, 1004. it is stated that the total present 

 development of this company is 43,000 horsepower, and that work 

 is now in progress on an additional 100,000-horsepower plant to 

 be entirely located below the cliff. Of this quantity 10,000 

 horsepower is by water from the company's waterway. 



This company has a grant from the State of the right to draw 

 from Niagara river as much water as can be taken through a 

 canal 100 feet wide and 14 feet deep. 



To July 1. 1897, about 100,000 cubic yards of material had been 

 taken out at a cost of $250,000, the average cuttings in the original 

 canal from the surface of the ground to the surface of the water 

 being about 8 feet. 



The development by this company is very interesting. A bulk- • 

 head is located at the top of the high bank with a forebay back 

 of it connected with the main hydraulic canal by a shortbranch 

 canal. From the forebay a large penstock leads vertically down 

 the cliff to a powerhouse located directly on the shore of the 

 lower river. In this power-house horizontal turbine water wheels 

 are placed, with dynamos directly connected, the power therefrom 

 being transmitted either to the mills on the bluff above or to 

 establishments at a distance. Without taking into account the 

 cost of water in the canal, the cost of the development of power 

 in the way in which it is now being developed by this company 

 may be placed at §35 per horsepower. 1
