The arrangement of the various buildings belonging to the com-pany is shown in Fig. i. In the engine area arc three generatingunits, each and every consisting o( an horizontal tandem compouiul en-gine rated at 150 h. p. at two.35 r. p. m., belted to a six-pole con-tinuous existing soo-volt generator. The generators had been suppliedby the Union I^lektricitats-Gesellschaft. of Berlin. Each enginehas two fly-wheels, 1 carrying the generator belt, and the otherthe governor belt, and the machines are arranged to run con-densing or non-condensing as preferred. A surface condenser of theWorthington kind has been installed. The pumping method is ina separate area adjoining the boiler area as shown in Fig. i.There arc two Worthington feed pumps every obtaining a capacityof 2,500 gallons per hour, two injectors obtaining a capacity of 800

The boilerfeed pumps draw straight from this tank, forcing the water througha Green economizer ahead of it reaches the boilers. In the boiler area are three boilers as shown in Fig. 2. Thesearc of the double drum variety, and have a heating surface of 1,030sq. ft., and a normal evaporating capacity of 3.300 lb. per hour.The drums are 6 ft. 11 in. in diameter, the upper drum getting 20ft. long and the decrease a single 23 ft. long. The two water and steamspaces arc straight connected by enclosed tubes. Each drums possibly separately fed, and any section of the feed pipes amongst theboilers and pumps may be cut off. The fuel employed is .•^ustraliancoal, despite the fact that it is proposed to make use of petroleum waste for thispurpose at an early date, as this material can be secured on thegrounds
