Thecost of fuel for a steam engine on a basis of 6 pounds of coalper horse-power is the equivalent of 1 1-5 cents per horse-power hour, but this economy cannot be obtained in smallengines that are in most common use. Mr. Whitney estimatesthe average consumption of small engines at about 10 poundsof coal per horse-power hour when actually at work, and thecost of the power at 2 cents for the same unit against 1 1-5cents for the gas engine.

Cheaper gas may l>e expected to induce a general increasein the use of gas engines, and a movement now on foot inBoston may exert a marked influence in this direction.
