Small compared to the quantitative increase in U. S. productive capacity in 1920-29, the Five-Year Plans represented a greater rate of increase. They doubled Russia's industrial stature, made her an industrial power, left her self-sufficient in production of oil, coal, iron ore, manganese, cellulose, cotton, super phosphates. But it set a vast segment of the Russian proletariat moving from factory to factory, from village to city, in one of the great tidal movements of humanity that Tolstoy long ago described as the ceaseless wanderings of workmen over the earth. It ended uniform wages. Breakdowns, delays...
Welfare & Warfare. Yet, though Reich chemists are working night and day, Germany is less able today to support a long war than she was in 1914. With Lorraine gone the iron ore supply is not enough. The available soil, even including the Bohemian and what could be seized in Poland, Hungary and Rumania, is not sufficient to produce both fodder crops for the cattle and breadstuffs, sugar beets, potatoes, vegetables, flax and hemp for the 152,300,000 population of a Middle European empire. Intensive grain cultivation operations are now being set up in East Prussia, but most...
Since 1920 steelmaking has had a big swing to the open-hearth process. These furnaces, lined with dolomite (lime and magnesia oxide), are primed with plate scrap and limestone, then charged with pig iron, scrap and ore, and heated. Gas expelled from the limestone stirs the mixture, helps form the slag. A furnaceman spoons out samples, cools them to test quality, then adjusts the heat to get just the quality he wants. After about twelve hours the furnace is tapped, the steel ladled off. The Bessemer process is three times faster than the open-hearth, and correspondingly cheaper; but since...
Over Portland, Ore. one day last week buzzed a trim two-motored airplane that outwardly looked like any other U. S. aircraft, but inwardly was as different as a hickory basket from a ship's hull. For while the skeleton of other planes is built up of longitudinal braces, bulkheads and stringers, the framework of this Greenwood-Yates Geodetic Bi-Craft is woven of spruce strips. It resembles nothing more than a woven basket covered with fabric to keep out the breeze, powered with two 50-h.p. engines to pull it through the air. Its structure is called geodetic...
