...AUTOBIOGRAPHICAL NOVEL, by Kenneth Rexroth. With a cast of 1,000 people least likely to get into Who's Who, Kenneth Rexroth, last of the old bohemians, crams the stage of a crowded biography. Fortunately, the old political evangelist ceases to wave the flags of social revolt in favor of chronicling the reign of a minor king of the Big Rock Candy Mountain...
...just a year ago that the first wave of U.S. Marines, M-14 rifles clutched at high port, waded ashore at Danang. The landing came at a dismally low point in South Viet Nam's long struggle for independence, with the Viet Cong on the offensive and threatening to cut the country in half. The marines were the U.S. reply, the commitment of the first organized American combat units to the ground war in Southeast Asia...
...wild, almost desperate thought. Three closely spaced spectral lines on his photographic plate resembled hydrogen lines. But they were not in the blue segment of the spectrum where they belonged: they were superimposed on the red portion instead. Could they actually be hydrogen lines that had shifted to longer wave lengths...
...racing away from earth, Schmidt realized, the wave length of its light would be lengthened - just as the wave length of sound from a train's whistle lengthens (thereby dropping in pitch) as it speeds away from a listener at the railroad station. Such an effect on light is known to astronomers as a "red shift" because it moves the characteristic lines of spectral light toward the red, longer wave length end of the spectrum...
Homestake not only reopened but also prospered by introducing cost-cutting technical innovations. Among them: automated hoisting equipment; TV monitoring and short-wave communications; tungsten carbide bits, used to drill holes for explosives, that last for 450 ft. of drilling v. 16 in. for the old steel bits, and have doubled each miner's productivity. It takes an average three tons of ore to produce a single ounce of gold, but Homestake literally wrings out every ounce. The company salvages $300,000 worth of gold a year by such thrifty measures as washing workers' clothes and hands, vacuuming...
