The design of thistruck seems a year ago this road experimented with a new ashpan in order to avoid the serious trouble of cast iron hopperscracking under the heat. The result was So satisfactory as tolead to the adoption of the new plan. This construction em-bodies a cast steel frame, with plate steel side sheets. Theframe, being on the outside, is protected from the heat causedby accumulations of ashes inside the pan. All sheets arepunched to templets, and if one burns out, it is easily replaced,involving no further injury to the ash pan. With this con-struction the Brooks hopper slides are applied as indicated inthe THE NEW ASH PAN CONSTRUCTION, OF PLATE STEEL SHEETS UPON A CAST STEEL FRAME. 14 AMERICAN ENGINEER AND RAILROAD JOURNAL.

Thedistance between chain sprocket centers could be redu
