The high and low-pressure cylin-ders of the engine are 11 ins. and 19 ins. in diameter, respec-tively, and the stroke 11 ins. The generator has four poles,and gives about 150 amps, at from 500 volts to 550 volts, theset running at 300 r. p. m. The armature ofthe generator is pressed direct on to the ex-tended crank shaft of the engine. The ma-chine is compounded so as to give 550 voltswith a full load of 136 amps. The machinewill also carry a 25 per cent overload for halfan hour, and a 50 per cent overload for a fewminutes. The two 15-kw boosters are four-pole ma-chines, running at 575 r. p. m., the motor voltsbeing 500 and the booster volts 50. The main switchboard has thirteen whitemarble panels, 2 ins. thick, and is set in anangle-iron frame. Som
