Although long a member of the medical profession,Dr. Harris was formerly a mechanical engineer, and the sub-ject of fuel economy has always been of great interest tohim. It is well known that the imperfect combustion in an ordi-nary furnace causes the generation of carbon gases of high. TRAIL CAR FOR PITTSBURG RAILWAYS COMPANY calorific value, which are utterly lost unless enough hot oxygenis introduced to consume them. To overcome this loss it is now common practice to increasethe grate surface for a given amount of fuel to permit in-creased air circulation by spreading the coal in thin layersover the grate bars. This, however, often works more harmthan good, for if too much cold air passes through the fuel thetemperature of the fuel gases is lowered and their volume in-
