PROPERTIES. The steel from which the pipe.-is, made shall halre approximately the following physical properties; Tensile strength not less than 50,000 lbs. per square inch. Elastic limit not less than one -half the tensile strength. Elongation in 811 not less than 20%. Reduction in area not less than 50%. BEND TEST. Veen required, a test specimen out lengthwise from finished pipe and filed smooth on the edges,.shall bend to an angle of 1800 with an inner diameter equal to.the thickness of the material, without fracture. THREADING. Pipe and couplings shall be threaded and tested according to Briggs Standard. Thread must be a good commercial thread and must not leak when subjected to an internal pressure of 600 pounds per square inch. The thread must not vary more than 1 1/2 turns either way.

SPOIL BANKS. The .materials excavated shall.be laid compactly along the side of the trench, and kept..trimmed up so as to cause as little in- convenience as possible to the public travel. In case the street is not wide enough to hold the earth without stopping the passage- way on the sidewalk, the Contractor shall eaect a board fence and keep a passageway - six feet wide - open. on said sidewalk.
