...Price spoke, his veterans' office approved the educational qualifications of still another new school. Its curriculum: deep-sea diving...
...year-old Cornelius Vanderbilt ("Sonny") Whitney, inheritor of $20 million, avid pursuer of the outdoor life (horses, deep-sea fishing, hunting, aviation). An instructor pilot in World War I, Whitney entered World War II as a major, served ably in Africa, the Pacific and Washington, came out a colonel with the Distinguished Service Medal...
...weeks later, another fisherman hauled in a 32½-pounder, then a world's record for Kamloops (now it's a 36-pounder). Then the rush began. Anglers converged on Pend Oreille, equipped with deep-sea tackle and high hopes. When the Kamloops bit, they bit hard. One man, rowing along the shore one morning with his rod draped over the stern, suddenly saw the rod fly up as if alive. He dropped his oars and dived for it, splitting his chin open on the boat's gunwale. The fish got away, taking rod & reel with...
...deep-sea divers working on the sunken British submarine Thetis were a scientific problem to famed Biologist J.B.S. Haldane. One day, early in World War II, Briton Haldane impetuously clapped on an oxygen mask and, breathing pure oxygen (to study its effects), "dived" in a pressure chamber to a depth of seven atmospheric pressures (200 feet). The experiment nearly killed the experimenter, but it proved to him that oxygen, under pressure, is a violent poison...
Nervous Knockout. Deep-sea divers generally have been fed pure oxygen and helium, pumped to a pressure matching the depth of their dive. Divers sometimes unaccountably passed out during relatively shallow dives (up to four atmospheres of pressure used to be considered safe). The British study, involving some 2,000 tests, proved that oxygen, forced into the tissues under pressure, somehow intoxicates the central nervous system and poisons the brain cortex. (Whales, biologists have observed, bypass the whole oxygen problem by collapsing their lungs during deep dives...
