Lombard governorfor regulation, and the exciter wheels with one type No. 2Lombard governor. Other engravings show the dam which forms the reser-voir in the process of construction, the entrance of the feeder, the exit of the 8-ft. feeders and the engineersresidence in the distance; also an end and side view of thepower house and a bank of three 8-ft. feeders now have been built into the dam for the future installa-tion of five additional 8-ft. feeders to supply 2000 hp. Thepower house is built of brick and is plastered inside andout with cement. Trimmings are of cut granite. All frame. MAIN PIPE LINE, 12 FT. IN DIAMETER supported every 12 ft. by steel saddles. The design of thesaddles where the pipe crosses an old river channel is shownin the above cut, where the pipe is within 4 ft. of the sur-face of the ground; the saddles are not provided with steel-post supports as shown, but rest on masonry pipe is provided with three expansion joints and isdesigned to pass water at a speed of 11 ft. per second dur-ing peak-load periods. In order to provide for slow veloci-ties on to the turbines the water is discharged into a reser-voir formed by building a second dam across a reservoir has a capacity of 500,000 cu. ft., and from itthe water is led to the turbines through feeders 8 ft. indiameter and 245 ft. long. Each feeder leads directly intothe water chamber of a pair of 48-in. horizontal cylindergate wheels, direct coupled to the generators. They weremanufactured by the Stilwell-Bierce & Smith-Vaile Com-pany. Each p
