THE POWER PLANT As may be seen from the view of the power plant it is con-veniently located for access to an abundant supply of water forcondensing purposes, being located at Karmous upon a canal stations to deliver the direct-currentsupply to the trolley wires. The steam generating equipment ofthe plant consists of ten boilers of theelephant type, arranged as illustratedin the accompanying illustration ofthe boiler room. They are designedto operate at a steam pressure of 135lbs. per square inch. They are hand-fired, using bituminous coal, and areequipped with Green economizers forthe heating of feed water. .The boilerfeed and other pumps used in theplant are Worthington pumps.

Two horizontal tandem-compound condensing engines, eachof which operating at 107 r. p. m., with a steam pressure of 135lbs., develops 800 hp. These engines were designed particularlyfor use with alternating-current generators, being guaranteednot to vary in angular velocity more than one-fourth of 1 percent per revolution under constant load; the governor is of the
