(2) Some of the theory obtained in college is never US d in industrial work: it is laid aside for future us if need be. (3) (iood common sense with a will to work and a mind that can think in that line of work are the es -entials for a college man in industry. (4) A gas engineer should be primarily a chemical engineer, with a good knowledge of mechanical engineering, electrical engineering, and mining engineei ing. To illustrate this point, one of the problems to be investigated involved running a steam engine, an electric furnace, two gas furnaces, making pipe coni. 'ions and pyromctry connections. For several days plumbing was first and chemistry second: joints, elbows, unions. T's. nipp! plugs, reducing elbows and pi: hreading were primary and carbon, hydrogen, en, and nitropen were secondary.

CARBURETED WATER GAS is made in two steps. First, usually coke is charged into the hot generator and made nearly white hot by blowing air through it. Then the steam is forced through the 1 coke.
