Steel Pipes for Sewers.

An engineer suggests that sewers of rive.ed steel pipe, coated with pure asphalt or other suitable compound, are in every way adapted to t leir purpose. It is claimed that for large sewers this pipe is cheaper than brick, lasts longer, and will not cave in. The editor of a leading engineering news journal, by way of comment on this suggest.on. says that before any city a .opts steel pipes fir sewers it must settle the question whether the sewage carries a sufficient amount of acid dr alkaline matte - to cau e corro-ion, and whether the steel could be so protected a; to prevent corrosion. Another question to be considered would he the relative cost of steel and iron pipe. Both steel an 1 iron can now be bought at marvelouslv low figures, and the difference in their cost is less than ever before. Most sewer work is done in streets that' are fairly accessible, and this fact in a great measure lessens the urgency of using steel pipe; on the score of lightness and greater ease cf handling. Furthermore, the advantage of cast iron is that it resists corrosion better, and furnist.es a gi eater thickness of metal which must rust away before leakage will occur.
