Many of the objections that obtained with the handSanders are overcome with the advent of pneumatictrack sanding devices. There was, perhaps, but one advantage in the oldhand sander- -that it would deliver more sand in agiven time -but this was offset by its many points ofdisadvantage. Too much sand on the rails makes atrain puh hard and, too, most of the sand deliveredby gravity at the mouth of the pipe falls or isblown off the rail, and is wasted, and the loco-motive, after a very few miles of continuous sand-ing, is entirely out of sand. To apply the handsanding device efficiently to both front and rear ofdriving wheels (as on switching engines) requiredtwo sand boxes instead of one, while with manyof
