A. W. Leland Eivers, of Charleston, S. C, has taken measures to secure a patent for an improvement in water tanks for locomotives, the nature of which improvement consists in constructing a tank in two halves, or with two separate chambers which are secured together fay bolts. Each chamber has a manhole on the bottom, for the hose, and the water can be let out of the one and retained in the other, if desired. The object of the im-psovement is to allow of one part of the tank being taken off and repaired easily, if injured, without disturbing the other, thus effecting a considerable saving in the course of a year on a railroad.
