They are Babcock & Wilcox water-tube boil-ers, with 126 4-in. tubes 18 ft. long and two 42-in. drums 9-16 of aninch thick and 23 ft. 3?^ ins. long. The boilers are built to carry200 lbs., but at the pressure adopted for the station, 160 lbs., theyhave a rated capacity of 250 hp, although they can develop 400hp.

The boilers were equipped with Roney mechanical stokers byWestinghouse, Church, Kerr & Company, and this plant has thedistinction of being the largest installation of mechanical stokers rightly claim the distinction of leader in number and capacity ofstokers as well as in character of equipment. A brief description of the present form of the Roney mechanicalstoker, which is playing such an important part in these large powerequipments, will be interesting at this time, when so many largeplants are being installed.
