interesting and helpful and which On another page in the same issue would call to their attention the many is an account of the growing use of ways in which lead is being used and the then newly developed tetraethyl can be used to accomplish both the lead treatment of gasoline, citing an routine and special objectives of their increase in the amount of lead used work, SS e are encouraged bv the for this purpose from 650 tons in numerous responses we have received 1927 to an estimated 4.000 tons in to believe that we have been success 1930.

A reduced tariff might permit a large part of these impor tations, if not all, to continue after the war, thus replacing a major market for domestic lead. (3) If it is desired to increase foreign production of other commodities such as food and rubber, which are vitally needed for our war requirements, we main tain that our "trading" position is obviously better if we leave in the hands of the proper Governmental departments the purchasing negotiations for lead. (4) Lead is a war material, needed in munitions, submarine, tank, and other storage batteries, signal corps cables, solder, bearing metals, degaussing cable, red lead, tetraethyl lead for gasoline and many other indispensable war uses.

Tetraethyl Lead Helps Engine Efficiency Boost TRl CK Heel operators have profited from a big bonus since 1949.

Materials handled in these hoods would include tetraethyl lead, radioactive materials, beryllium compounds, carbonyls, benzene, VCM, and materials having a similar high order of toxicity. 2.
