Acetyleneis used for lighting trains on the dustlessroad of anthracite, and it can also beused for a shop illuminant. The D., L.& W. have a neat little generating plantcapable of supplying gas for about 75ato 1, 000 cars a month, and the way thatthey do it is this: In a neat little two-story building thereare a couple of generators which arelarge circular tanks, filled with water, and from a hopper above containingwhat the man calls carbide, the op-erator is able to drop what amounts toa good sized handful at .a time. Whenthe calcium carbide drops into the water, acetylene gas is given off, and it raisesin large bubbles to the surface and isconveyed through suitable pipes to agasometer capable o
