This must all be donewithout extending the wheel base too much to prevent the en-gine from curving. Now, there is not much difficulty in doingall these things, excepting supplying a firebox of the size andproportions designated. Leaving out compound locomotives, the most marked depart-ures in design which have recently been made have been theattempts to supply such fireboxes. In all of them all the driv-ing wheels and axles have been placed in front of the firebox,and the latter is carried on a pair of trailing wheels. This hasbeen the case in some locomotives of the Atlantic and Colum-bia types, and later in Mr. Delanos locomotive, which was il- Supplement to American Engine. A RAILROAD.

It must be admitted that all of these forms of locomotiveshave been accepted with a good deal of hesitation by locomo-tive superintendents and master mechanics generally, whichmay in part be due to the fact that in a number of instancesthe feature which is the distinguishing merit of this form ofdesign has been omitted—that is, the wide fireboxes—and inone or two other instances unfortunate deficiencies of designof such fireboxes resulted in their failure. In this evolutionaryworld every newcomer must adapt himself or itself to Its envi-ronment. Many ca
