Electrical news and engineering . running down the whole length of the building will bo part ofthe equipment of the power house.

The framework for the crane and trusses is main section, comprising the water wheel and generatorroom, is 110 feet long by 40 feet wide. To this will be added agate house over the tail race, a transformer room at the downstream end, and an office section. A 15-ton travelling crane. Two 100 h. p. Exciters—Sherbrooke. 22 feet long, inclined at 30 degrees to the vertical. The gov-erning of these units is effected by Lombard governors ofliberal capacity to insure a very close regulation. One of thesewheels, tested at the factory at Holyoke, showed the very highefficiency of 85 per cent, at slightly over three-quarter two turbines, having a capacity of 100 eachat 750 , are of the single horizontal scroll case type. Theywill take their water from a common feeder opening from thestandpipe through hand operated gate valves. They are con-trolled by Woodward governors. Electrical Equipment. This part of the installation has been carefully designedto conform with the best modern standards. The three mainunits have a rated capacity of 940 at 2,300 volts, 3phase, 60 cycles, 360 These generators are of ratherspecial design in order to insure close regulation and absence ofhunting. The rotors will have a weight of 24,000 pounds each,
