The level of the platform iseven with that of the main operating room floor, so that it maybe freely used by the water tenders and by the operating engi-neers without being obstructed by the firemen or their platform in front of the boilers will also be used for clean-ing purposes and, in this respect, it will do away with the un-sightly and objectionable scaffolds usually employed for thiswork. The water tenders will also be brought nearer to the. VIEW IN THE PIPE AREA OF THE STEAM PIPING CONNEC-TION TO A MAIN ENGINE water columns than when operating on the main floor. Thefeed-water valves will be regulated from the platform, as wellas the speed of the boiler-feed pumps. Following European practice, each boiler is provided withtwo water columns, one on each outside drum, and each boilerwill have one steam gage above the platform for the watertenders and one below the platform for the firemen. The stopand check valves on each boiler drum have been made spe-cially heavy for the requirements of this power house, and thisspecial increase of weight has been applied to all the severalminor boiler fittings. Hand-fired grates of the shaking pattern have been orderedfrom the Gibson Iron Works, for thirty-six boilers, and foreach of these grates a special lower front has been fronts are of sheet steel, and the coal passes down to thefloor through two steel buckstays which have been enlarge
