One independent air-pump and a circulating pump for. i- iii. IJ.—Fire-boat Nt-w-VorRer. the condenser are provided. The condenser is of the tubular pattern, with about sq. condensing surface. Steam-steering gear and engine are provided in addition to theregular hand-steering apparatus. For signaling, a steam-chime whistle and a steam calliopeare provided. The pumping-machinerv is of great power. It comprises two duplex vertical direct-actingpumps. Each has two steam and two water cylinders. The steam-cylinders are 16 by 11 in. stroke. The water-cylinders of the same stroke are of 10 in. working pressure allowed for the water-cylinder is 200 lbs. to the sq. in. The pumjisdraw water in through two 16-in. suction-openings in the bottom of the vessel, to whichsuction-pipes are connected. The discharge is delivered through ))i-in. connections into a 12-in. main, that runs around the trunk of deck-house, and which is provided with numerousconnections for hose-couplings. Several 12-iii. valves are placed
