The vest. practice is to encircle a city with a larre vipe tren sunrly the different parts by feeders, lending fror the main nine. This is not. possible in “ewayso because of tho toposraphy, part of the town being in a valley and the rest on separate hills. Because of thts there are single pipes which result. in four dead ends, there bein now no chance to close on another vipe. The ordinary city should have the large mains arranced geo that smaller cross pipes can be fed from both ends. In this principle lier tne biz advantare of a szridiron syste, since the cross main is equivalent to two piper and can fure- nish double the number of fire streems with the same lora of heed, or the sar.c number of Tire stress with one fourth the loce ne when fed fror one ent only. Another advantsare af the circulating eystem ie tneat. any pert of tne avetem rey be cut out for repairs an) the reet of toe eitv need not be affected. Yead ends are also objectionable on eccount of stagnation which existe in the Pines ant the detertoration of water whicn is lirely to enceue. The pdipes will rust and so-called iron “tubercles” will form on the inside. Also ovinm to stagnation tho water may ecmulre a distinct chalybeate turte and appear unsirshtly from flakes of iron rust. “esd ends should be flushed quite frequently to be rept in the beet of condition. Cnoe dead end would be elivinated in our pronvosed extension.
