When coal for this purposeis used on vehicles it has been found dif-ficult to regulate the supply to the fur-nace with the accuracy necessary to pro-duce satisfactory running, while thescrubbing process has not infrequentlybeen found defective, the tar declining tostay behind entirely in the scrubber. Iutit has always seemed to me that be no insuperable difficulty inusing heavy oils in this fashion, regulat-ing the Iced to some kind of furnace sim-. \Ki-:K \ .\l.\ I- the model is not on the gearing, as appliedto a locomotive, but is very convenient asapplied to a model, as it avoids the neces-sity of using a reach rod with reversinglever and attachments, as in the modelthe gear may be placed in the forward orbackward motion by loosening an ad-justable screw attached to the sliding pinin the quadrant when the screw may betightened at the desired place on thequadrant, the reverse being readily movedby hand. Liqtiid and Other Concentrated Fuel. The high price of gasoline and the de-mand for smokeless combustion are lead-ing to various experiments with fuel andfurnaces that will take the place of oilfuel. Powdered coal makes a highly ef-ficient and smokeless fuel when burned,and furnaces suitable for its combustinn,while gas produced by special isgiving promising results. Our Glasgow agent, A. F. Sinclair, inone of his weekly contributions to theGlasgow Herald, writes about a liquidfue
