Locomotive boilers are handicapped by the requirement tnatthe boiler itself and all its appurtenances must come within rig-idly defined limits of space, and by the fact that they are forcedto work at very high rates of power. Notwithstanding thishandicap, it is apparent that the zone of practicable improvementwhich lies between present-day results and those which mayreasonably be regarded as obtainable is not so wide as to makefuture progress rapid or easy. Material improvement is lesslikely to come in large measures as the result of revolutionarychanges than as a series of relatively small savings in the sev-eral items to which attention has been called.

Southern Pacific Company. It has been suggested a number of times that with oil burninglocomotives it would be possible to reverse the customary direction of running and by placing the tender at the other end ofthe locomotive the engineer could be located where he wouldhave a perfect view ahead without separation from the firemanand leaving him in a position where he could watch the condi-tion of the fire, height of water level, etc. This idea has beenput into practice on some of the Italian railways, and, as is
