Steam-steering gear and engine are offered in addition to theregular hand-steering apparatus. For signaling, a steam-chime whistle and a steam calliopeare offered. The pumping-machinerv is of fantastic energy. It comprises two duplex vertical direct-actingpumps. Each and every has two steam and two water cylinders. The steam-cylinders are 16 in.diameter by 11 in. stroke. The water-cylinders of the same stroke are of 10 in. diameter.The functioning pressure permitted for the water-cylinder is 200 lbs. to the sq. in.

When in working con-dition, tlie base is broadened by jacking up and throwing the weight on the functioning side outto a third mil, 7 ft. ilistant from the line-rail. The ladder over which the buckets travel ishung on an axis on the l^ack of the machine, but throws the center of gravity toward theworking side, and. to offset this, ballast of railroad-iron is loaded on the extension on the Imckof the maciiine. The boilers are usually horizontal, giving a low center of gravity, and thewater-tank of iron and a coal-bunker of inm are placed on the boiler-end of the platform.The endless chain of buckets is operated on the more than-and-beneath system. The liuckets aremade with a (piadrangular hemispherical face and no Ijack. The hyperlinks are hung at the rearof the buckets.
