...reason to respect Dirac's reasoning. He had earlier predicted the existence of a positron, or positively charged counterpart of the electron. The positron was subsequently discovered during cosmic-ray experiments in 1932, but the monopole proved more elusive. Physicists searched for it without success in everything from ocean-floor minerals to meteorites and moon rocks...
Missing Deposit. More subtle clues came out of the ocean depths, although few scientists at first recognized their importance. By 1959, Columbia University's marine geologists had completed charting a mysterious 47,000-mile-long chain of undersea mountains and ridges that twist through the middle of the major oceans like the seams of a giant basketball. Strangely enough, the water temperatures near these ridges are considerably higher than those elsewhere in the ocean. In addition, there are ocean-floor fault lines or cracks that were apparently caused by movement of the seabed itself. Although the oceans are billions...
When Rouse presented his little globe and big theory to Colorado School of Mines Geochemistry Professor Ramon Bisque last September, Bisque was overwhelmed by the implications. "My God!" he said. "Yes," Rouse solemnly agreed. In the months since, Rouse and Bisque have discovered that primary mineral deposits, mountains, ocean-floor ridges and trenches and island chains also lie along the Rouse belts. They have even correlated variations in the earth's magnetic and gravitational fields with their all-telling circles...
...pearl bed off a nearby island. Because of the rescue Barker loses the race and his ship. But with the pearls the dying man gave him he buys back the boat and sets out for the pearl-island. Schultz hears of it and follows. While Barker is on the ocean-floor investigating, cannibals attack his ship. Sensing that something is amiss Barker cuts the connecting lines on his diving suit and with commendable sureness of foot and direction walks to shore. He wanders about dazed, unable to get his suit off, and eventually stumbles upon the cannibals who are about...
Since then he has improved the observation tube. It is flexable, having joints like the bellows of an accordion, and provides comfortable seating-room for six people at a time in the chamber at its lower end, from which they may observe the phenomena of the ocean-floor through a pane six feet in diameter. The tube, which may be raised or lowered at will, is suspended from the side of the mother ship...
