Solid red brick were used in the no engine fly-wheel is required, the revolving field beingmade of sufficient diameter and weight to give all the fly-wheel effect required. In other words the generator isbuilt on the fly-wheel instead of beside it. This does awaywith one huh and set of spokes, and makes a simpler,neater looking unit. The fly-wheel effect of the re-volving field is 81,700 lbs., at a radius of ft. Theother unit is a similar Rice-Sargent engine, cylinders 20ins. x 40 ins x 42 ins., rated from 800 hp to J 500 hp, accord-ing to cut-off, and operating at 107 r. p. m., direct-con- K.
