with the sizes of the buildings. A description of one ofthem will, therefore, answer for all. It should be noted thatthere are two heaters in the locomotive shop, offering the ad-vantage of closer regulation of the heating in moderateweather than would be possible to obtain with a single largeheater. Each of the locomotive shop heaters has 22 sections, eachhaving SO eight-foot pipes and giving a radiating surface of14,740 lineal feet of one-inch pipe. The blower is the Bostonsteel plate exhauster with full housing. The height of thefan is about 10 feet, the fan wheel is 72 inches in diameter by34 inches wide at the periphery, and 42 inches wide over all.The inlet has a diameter of 50 inches, while the outlet is 44by 40 inches. The housing is of heavy steel plate, braced withT and angle iron. The fan is directly connected to a seven byseven-inch engine, as usual in this system of heating. Thesteam manifolds are subdivided and piped so that either live 114 AMERICAN ENGINEER, CAR BUILDER

They are providedwith concrete floors, brick side walls and plank covers. Theheating pipes extend north from the power house a distanceof 780 feet and south 890 feet. They carry a pressure of 30pounds per square inch. All of the condensation, except thatfrom the heaters themselves, is returned to the boiler househot water tank. The steam piping was put in by Messrs. IsaacCoffin & Co., of Boston. By returning to the plan of the pi
