...drought and the cost-price squeeze, have become too enmeshed in the U.S. subsidy program ever to vote their own way into the uncertainties of a free market. The 1958 quotas will do little to solve wheatmen's problems. Despite the acreage limitation program and the soil-banking of more than 12 million acres (in reality often poor land) at a cost of $231 million, the 1957 crop promises to be only a fraction smaller than last year, further adding to the nation's ominous 1.3 billion-bu. surplus...
After many cycles of this, they opened the jars. The dry soil inside was still alive with bacteria which had triumphantly survived "Martian" dryness and cold. The hardiest strains could reproduce during warm spells when the moisture content of their soil was only two-fifths of 1%. When the moisture rose above 1%, as it may during the Martian spring when the icecap melts or evaporates, the bacteria throve...
Mars Chamber. Last week Dr. Strughold reported at Flagstaff that this experiment has been performed successfully by Dr. Roland B. Mitchell and Lieut. John A. Kooistra Jr. of the Air Force School of Aviation Medicine. They collected soil samples from the high slopes of Mt. McKinley, the Painted Desert and the Grand Canyon, where the climate in some respects is almost as tough as on Mars. They put the samples in jars and replaced the oxygen-rich earthly air with dry nitrogen. They lowered the moisture content to below 1% and reduced the pressure to 1.2 Ibs. per square inch...
BUMPER WHEAT CROP is due despite retirement of more than 12 million acres into soil bank, may total only 3% less than 1956, thus piling up bigger surpluses. Farmers retired poor land, are producing more on good land, while drought-breaking rains have already pushed winter wheat harvest 27% above ten-year average of 18.6 bushels per acre...
...sandy tip of a new superhighway pushing across the hills from Richmond to the industrial town of Crockett, an army of mammoth machines comes noisily to life; their motors growl and their exhausts spout blue fumes into the mountain air. Tough, broadnosed bulldozers hungrily tear up the soil; potbellied scrapers scoop and level it; lumbering compact-ers press it down with their massive weight. Directly before the machines looms a 500-ft. hill that stood in the way of the inland-bound gold seekers of the 1840s, forced the Southern Pacific railroad and later a highway to slink humbly around...
