From the intake, ten penstocks carry the water downto the power house which extends along the river bank. The power house is a one-story brick structure, 70 ft. 10ins. x 392 ft. inside. The house is divided lengthwise, intotwo rooms by a brick wall 6 ins. thick. Across the upper endof the building is the transformer and switchboard room, andthe remainder is divided by the wall mentioned into generatorand wheel rooms.

Each of the ten tubesconnects with a wheel case that contains a pair of turbinewheels, mounted on a horizontal shaft. In eight of these tubesthe turbines are rated at 5000 hp each, under a head of 80 ft.,and in the other two cases the wheels are rated at 3400 hp. Thelarger wheels are direct-connected by shaft extending throughinto the generator rooms to generators rated
