The cover, d. closes the box while the turbine cleaneris in use. Such a truck can be made at a moderate cost bya blacksmith, carpenter and pipefitter. If it is profitable toconstruct permanent metal platforms for cleaning the ver-tical type of water-tube boilers, would it not seem equallyprofitable to supply plants having horizontal water-tube boil-ers with devices for similar work. In addition to the branches from the auxiliary mainwhich have already been described, there are numerous low-pressure lines. These lines will be described more fullyunder Class H—Low-Pressure Water Lines. Ordinarilyit would be safe to assume that there should be as many volume of piston displacement. If absolute pressure is as-sumed as 15 pounds, the piston displacement in such pumpswould reduce the pressure in the cylinder to poundswhich, in case of starting a pump without priming, wouldmake the head about 2i^ feet l
