...would be a provocative gesture even if excused by Japan's alleged fortification of islands in the absorbed mandate groups (Caroline and Marshall)-and particularly when viewed in connection with the British desire to control Japan's approach to the Netherlands Indies and British Malaya (oil, coal, rubber, food). More provocative, Guam is only 1,356 miles from Yokohama...
...Deal's dam program will not harness all this, experts foresee a big surplus over municipal and irrigation power needs. They also claim they know how to mop it up-build electrochemical factories near damsites, with hungry electricity-eaters like furnaces to produce calcium carbide (from limestone and coal electrically heated to 4,000° F.), acetylene, alcohol, acetone, fertilizers, insecticides, plastics. One modern, three-electrode calcium carbide furnace requires 225,000 amperes-enough current to light a million and a half household lamps...
Since October 1, 1938, when Newspaper Guildsmen walked out on city-wide strike, no daily newspaper has been published in Wilkes-Barre, Pa., a coal-mining and silk-weaving city whose retail stores serve about 300,000 persons. Deprived of their No. 1 advertising medium, the five biggest Wilkes-Barre stores have distributed a weekly "Shoppers Bulletin" to 73,000 homes. (Total circulation of the dormant evening News, Times-Leader and morning Record: 73,000.) Smaller stores have combined to publish a 24-page tabloid "Buyers Guide" with about 53.000 circulation, which also takes paid classified ads. By agreement...
...will be so for billions of years more, have long cudgeled their brains for a reason why. Most favored of recent theories is that hydrogen is the fuel. It is known that the sun does not "burn" hydrogen, in the sense of releasing stored chemical energy as from coal; it physically changes fragments of hydrogen atoms directly into radiation. But the question remains: Just what atomic processes enable the hydrogen to be utilized as fuel...
...from waste, using liquids of higher specific gravity than water, has been used for nearly a century. For over three decades E. I. du Pont de Nemours & Co. has been trying to devise an economical flotation method for separating impurities such as shale and slate from low-grade anthracite coal. For "parting liquids," they needed mixtures of controllable specific gravity up to three times that of water. Pentachlorethane and tetrabromethane filled this bill-after the Du Pont men worked out a way to use them over & over again cheaply...
