It is discharged througha galvanized duct into the boiler room above the main steam header is located along the divisionwall on the boiler-room side, and the steam connectionfor the turbine is taken off above the boilers and passesthrough the division wall direct to the turbine.

Steam for the auxiliaries istaken off a short distance above the bottom of the dropleg. The accident was due to a failure in a 2-in. union ina pipe between the bottom of the drop leg and the 702 Electric Railway Journal Vol. 52, No. 16 steam trap, about 6 ft. from the bulkhead door in thewall of the air duct leading to the generator. This doorwas necessary for removing condenser tubes. Thisbulkhead door was built to insurance specifications andwas originally a close-fit. A slight inequality in themason work at the bottom had been produced, however,in removing condenser tubes. Steam from this leak atthe union was sucked through the bulkhead door intothe air duct and the generator. The damage to the generator consisted of the burn-ing off of three leads from the
