HUGE GENERATORS YIELD BEAUTY TO PHOTOGRAPHER
Throbbing electric generators, the machines that are the heart of the great system supplying light and power to more than 120 millions, are odd and beautiful subjects for the talented photographer. In the picture on the cover, Rittase of Philadelphia has caught the spirit of one of the largest hydroelectric generators.
It is one of the seven 54,000-horsepower units of the Conowingo plant on the Susquehanna River in Maryland. This plant supplies a large share of the industrial load of the Philadelphia district and is designed so that its 378,000-horsepower installed capacity can be increased at the demand of the market.
