To day tlie automobile for traction is con-structed in a great variety of forms and for avariety of special purposes, and steam, air, va-por, and electric drives are employed ; the latterfinding extensive use in the cities, where cun-cnt is easily obtained for charging its batteries ; thefirst-named motor fluid is used for the heavierwork, and petroleum vapors serve well in long-distance work of a lighter character. All are ina tentative stage in the sense that no one can sayyet which, if either, will ultimately prove themost generally useful; but it would now seemextremely probable that all will continue, for along time to come, to find employment in one oranother of the many branches of automobilework looming up before the mechanical present it can only be said that for heavywork, such as is the subject of our discussion,and especially for long-distance tiansportation,steam seems likely to retain that preeminencewhich it has acquired during the two-thirds of a. thobneycrofts steam wagon. century in which it has been growing up to itstask and evolving satisfactory forms and propor-tions of moclianism. The electric motor andtraction engine is proving itself capable of doinggood work wherever current can be found witlicertainty, of the riglit kind and in ample quan-tity whenever demanded, and the later vaporengines are coming into use for intermediateconditions where curient is not to be obtained aswanted and where rapid motion over long routesis desired. !~>team road locomotives are in use inthousands and have been numerous, whereverextensive operations have been carried on, formany years. Petroleum vapor machines ai-enow built in hundreds, and tlie electro-mobileti-action engine is coming to be a familiar machinein cities, at steam railioad tunnels, and in compressed-air automobile finds a placewhei-e air is stored for use in accessible locationsand ample volume.
