In other respects, excepting of course the al-terations in the boiler necessitated by the application of thesuperheater, it does not differ from the remainder of the order. This design of superheater, the details of which are shown inthe illustrations, is a distinct departure from the arrangementpreviously applied by locomotive builders 111 this country andovercomes most of the defects that service has shown the formerarrangements to have.

These defects for the fire tube super-heaters have been, in general, the large number of steam jointsto inspect and maintain, the difficulty of getting at the jointsbetween the superheater pipes and the steam headers; the ab-sence of an opportunity for taking care of the difference in ex-pansion of the superheater pipes, thus leading directly to leakyjoints: and to the liability of nuts and screw threads in theheaders to corrosion.
