With this system of automatic thermalcontrol, there is no necessity of using avariable number of coils to meet the re-quirements of the outside all or none of the coils are in useat any one time. In ordinary practice the thermometers. FIG. 7.

In order to equalize the 236 RAILWAY AND LOCOMOTIVE ENGINEERING September, 1922 distribution of heat, the amount of radiatorsurface is made greater at. the ends thanat the center. A system of piping that isrecommended for the accomplishment ofthis purpose is shown in Fig. 8, using merce. The reports from our inspectorsindicate a very general letdown in the mat-ter of inspection by the carriers whichgives cause for concern. The carriers re-port various reasons for not making these
