Electric railway review . handling ofloose and wet earth, the laying of pipe on a soft bottom whilewater is flowing and difficulties with the men who are doingthe work, because they must either be ignorant and incompe-tent men who are obliged to do such labor or if more capa-ble, they are working with a grievance. For such work sewer pipe can be used and satisfactoryresults obtained, if the work is properly done, but under such conditions as prevail in this character of work it is nextto impossible to lay sewer pipe properly. Cast-iron pipe ismade in longer lengths which affords an opportunity forsupporting the sections by filling around the centers leavingthe joints clear for caulking. If pumps are used to keep thewater away from the work it will be necessary to have oneon either side of the hole in which the work is carried onso that the water will not interfere with the leading of thejoints. Another method of constructing such line is illustratedin Figure 215-(Fl-2). With this method the larger part of Sp^. Figure 216—(F1-3). the cost is for material as the work can all be done withcommon labor. Referring to the illustration the form, a, Ismade up of plates connected by handles in the shape of aninverted U. In beginning the work the trench is first dug,then the pipe, b, is screwed together and placed in approxi-mately its final position. The metal form is then set aboutthe pipe as shown in the drawing, and the space outside ofthe form filled with dirt while the inside of the form isfilled with concrete to encase the pipe. As soon as the con-crete and dirt have been rammed the form is withdrawn andthe trench then loose filled up to the point, d, at the bottomof the planking. With this type of construction old pipemay be used as it is surrounded by concrete through whichno water can leak. The work can be carried on even whenthe trench is wet as the pipe may serve to lead away thewater during the progress of the work and the concrete canbe placed in water. Two o
