This is at least as simple as the present method of making alumina from bauxite ore, which is by no means pure when mined. Its gross impurities, such as sand, are removed by crushing, washing, sifting. It is then dissolved in hot caustic soda or "lye," which does not dissolve the subtler impurities. When the hot lye cools in towering tanks, pure aluminum hydroxide separates from it and is ready to be baked and electrolyzed...
...Ordinary soil mixed with 15% cement paves the three 3,000-ft. runways of a new 300-acre airfield owned by Brewster Aeronautical Corp. in Bucks County, Pa. This saved hauling countless tons of gravel and sand to mix with the cement, cut costs 40%, saved time too. The cement-and-dirt pavement can scarcely be broken with sledge hammers, can easily absorb the pounding of Flying Fortresses, is expected to last over ten years.

...Mullet Line's future under Harry Edwards looks bright. Specifications for a new Marine air base at Cherry Point call for 32,000 carloads of sand and gravel-more than twice the line's normal annual traffic. Soon to start at Morehead City is a $5,000,000 Marine supply base which will mean still more carloadings...
