_Auxiliary steam pipes._--The five single-ended boilers and those in boiler rooms Nos. 2 and 4 had separate steam connections to the pipe supplying steam for working the auxiliary machinery, and the five single-ended boilers and the two port boilers in boiler room No. 2 had separate steam connections to the pipe supplying steam for working the electric-light engines. A cross connection was also made between the main and auxiliary pipes in the reciprocating-engine room, so that the auxiliaries could be worked from any boiler in the ship. Steam pipes also were led separately from three of the boiler rooms (Nos. 2, 3, 5) above the water-tight bulkheads and along the working passage to the emergency electric-light engines placed above the load line in the turbine room. Pipes were also led from this steam supply to the pumps in the engine room, which were connected to the bilges throughout the ship. _Main steam pipes._--There were two main lines of steam pipes led to the engine room, with shut-off valves at three of the bulkheads. Besides the shut-off valves at the engine-room bulkhead, a quick-acting emergency valve was fitted on each main steam pipe, so that the steam could at once be shut off in case of rupture of the main pipe. _Condensing plant and pumps._--There were two main condensers, having a combined cooling surface of 50,550 square feet, designed to work under a vacuum of 28 inches with cooling water at 60° F. The condensers were pear shaped in section, and built of mild steel plates. Four gun-metal centrifugal pumps were fitted for circulating water through the condensers. Each pump had suction and discharge pipes of 29-inch bore, and was driven by a compound engine. Besides the main sea suctions, two of the pumps had direct bilge suctions from the turbine room and the other two from the reciprocating-engine room. The bilge suctions were 18 inches diameter. Four of Weir's "Dual" air pumps were fitted, two to each condenser, and discharged to two feed tanks placed in the turbine engine room. _Bilge and ballast pumps._--The ship was also fitted with the following pumps: Five ballast and bilge pumps, each capable of discharging 250 tons of water per hour; three bilge pumps, each of 150 tons per hour capacity.
