...Chert (gravel) cost the Government $80-90,000 too much. Low bidder was the Cartwright Construction Co. at $1.63 per cubic yard. But Cartwright's contract was canceled, Memphis Stone and Gravel Co. took over at $2 per cubic yard...
...eastern bulge, A.D.P. took over another Air France field, flanked by an extremely powerful Lati radio station. Lati planes still use this field too, almost grazing the heads of A.D.P. workmen. To enlarge the runway from 800 to 1,550 meters, A.D.P. is moving by hand labor 120,000 cubic meters of soil, cutting and filling spots often 20 feet off-grade. But Superintendent Fred Wohn had trouble getting enough of the necessary small, hand-pushed dump trucks. A German contractor had some; when Wohn tried to rent them for the A.D.P. project, he flatly refused. Wohn finally...
Magnesium is everywhere. It is a vital ingredient of chlorophyll, and without it leaves would not be green. Every cubic mile of sea water contains 5,700,000 tons of it. Whole mountains of its ores lie among the Austrian Alps, the southern Appalachians, the Sierra Nevada. The far Western States are strewn with it; salt lakes are saturated with it.

...individual dustlike particles in a cubic centimeter of metal powder may have a total surface of approximately 384,000 square centimeters, making a tremendous amount of surface energy available ; but even so the cold-pressed briquets are not very strong and can be easily broken by hand unless they are strengthened by sintering-consolidating heat treatment by baking at temperatures well below their melting points. This heat also shrinks the pressed part, in some cases very little, in others 20%. Yet in each metal the shrinkage is controllable enough so that parts can be made precise to within...
