The Pifth Exposition of Chemical Industries was impressive in its showing of the completeness of the development of American chemical industry. Those industries whose development has completed our independence were well represented. The by-products coke in-dustry has reached the point where plentiful supplies of organic raw material are assured, so plentiful that benzol. toluol, xylol mixtures are offered as a motor fuel a t a prim that competes with gasoline. The production of naphthalene is so great that we now have a surplus for export. Paracoumarone resin of American origin is now available a t a low price.

American-made tungsten, molybdenum, cerium, vanadium, uranium, and titanium, as metals and as salts, are available for commercial and research use. For research use also there were exhibits by firms which are producing rare bacterio!opicaI sugars, bacteriological stains, organic chemicals, and other materials that have formerly made
