...make up the balance by shipping vast stores of raw materials that the U.S. badly needs. Thus the U.S., which will scrape the bottom of its manganese and tungsten deposits in three years, will be able to stockpile these from Russia, along with high-grade molybdenum, chrome, mercury, zinc...
...water, which is an excellent electrolytic bath, the metal is swiftly eaten away. Durham had no idea where the metal went, but he hit on a simple way to stop it: suspending in the water another metal higher in the electrolytic scale. Thus, when he installed a piece of zinc, electrically wired to the ship, near a bronze propeller, the propeller picked up zinc deposits instead of losing bronze...
Durham & Cheadle then developed a zinc alloy for the job (pure zinc soon gets coated with an oxide that interferes with electrolysis), and adapted their discovery to protect condensers, hulls, bulkheads, ballast tanks, etc. The device has already worked well on dozens of ships. So far as condensers, specifically, are concerned, Cheadle figures that his electrolysis eliminator doubles or triples normal life...
...hunters are 350 U.S. geologists. They have bagged millions of tons of war-critical ores. WPB has just scratched aluminum and zinc off the list of U.S. shortages. Copper may soon follow suit. The Government now knows of big U.S. deposits of manganese, vanadium, tantalum and chromite-not one of which was produced in quantity in the U.S. before the war. Already the nation can produce most of its own chromite and tantalum (crucially important in a secret war job). The hunters have also discovered 3,000,000 tons of high-grade bauxite (for aluminum), new sources of tungsten, magnesium...
...Survey Director William Embry Wrather, who looks like a country schoolteacher, and chubby, loud-tied Chief Geologist Gerald Francis Loughlin. Since 1938 the Survey has sent forth hundreds of prospecting parties to promising fields from Alaska to Latin America. They have hunted for copper in Vermont, bauxite in Alabama, zinc in Wisconsin, oil in Alaska. In the past year alone the geologists have made more than 700 field investigations...
