...Navy's bathyscaph Trieste reached its goal last week: the bottom of the Marianas Trench, which is believed to be the deepest place in all the world's oceans. Manned by Jacques Piccard, son of the bathyscaph's inventor, Auguste Piccard, and Lieut. Don Walsh, the Trieste took 4 hr. 48 min. to settle slowly down to the Pacific Ocean's bottom, landing gently on soft silt that billowed up and looked like dust clouds when the lights were turned on. When the clouds cleared, Piccard and Walsh could see living creatures that moved unbothered...
...effects of guns, liquor, and women appear in Casablanca without seeming to be the cliches. Maybe it is because Humphrey Bogart is holding both the guns and his liquor, and maybe it is because Ingrid Bergman is the woman. At any rate, Casablanca is outstanding. Few people wear a trench coat or a frown as well as Bogie and no one can rival Ingrid in looking wistful...
Final target of Trieste and her crew is the Marianas Trench, which runs east...
...geophysicists, the ocean trenches are some of the most interesting places on earth. A well-supported theory holds that the trenches are places where the earth's crust is being sucked slowly into the depths by currents in the plastic inner material. When Trieste has penetrated the Marianas Trench and studied its rugged bottom, her reports may explain the origin not only of the earth's ocean deeps but also of its mountains...
...Revelle suspects that the trenches may be part of the mechanism by which continents grow. The first step, he thinks, is for a slow current in the earth's plastic mantle to start flowing horizontally and then curve downward (see diagram). Where it makes the dive, it drags down a strip of the crust, forming a V-bottomed trench which after many millions of years fills with sediment. Eventually the downward current in the mantle stops flowing. Since the mantle rock at its sides is heavier, it moves in, forcing upward the dragged-down crust and the sediments...
