W. General Electric genera-tors. Although each engine was only required to de-velop soo-horvse-power with its best economy, each ofthem has nearly doubled this requirement, having oper-ated individually a load of 900-horse-power. The regu-lation is sensitive and there is an elasticity in cut-off up toand including 3-4 of the stroke. These engines are not built of the same proportions asmill engines, but are of special design for the trying con- condensing apparatus. The feed water is pumped throughthe compound heater to a supplementary heater which.
