Following the Fifth Army in 1944 from the winter standoff in the mountains south of Rome to the headlong drive through the hills of Tuscany, he stays clear of both the trench-foot and the snafu schools of war writing. He explains why things worked rather than why they did not. His target is the "armed corporation" that has crossed the ocean to send U.S. steel flying at the enemy, bringing shiploads of filing cabinets and efficiency experts whose battle cries are phrases like "production quota" and "good management...
...boundary layer between the earth's crust and mantle by drilling off the coast of Mexico, so far has penetrated only ordinary, surface-type rocks. Last week, the Woods Hole Oceanographic Institution reported far better success with another method. From the fractured north wall of the Puerto Rico Trench, its research ship Chain has dredged up the first samples of "third layer" rock ever gathered...
...thick. Below it lies the third layer, which seismic waves have proved to be made of unusually heavy rock. The third layer is normally unreachable, but scientists making a seismic survey in 1959 got hints that it might be exposed on the sides of the Puerto Rico Trench. In 1960 Dr. Earl Hays of Woods Hole took photographs showing fractured rock on the trench's north wall...
Misplaced Pacific. To geophysicists, the Puerto Rico Trench is one of the most interesting places on earth. Lying north of Puerto Rico, it is something like the Grand Canyon sunk under three to four miles of water. Like other deep ocean trenches, it is believed to be a place where the earth's crust is sinking into the interior, perhaps carried down by slow, enormous currents in the plastic mantle. Since trenches are characteristic of the Pacific Ocean, where they abound, some geophysicists consider the Puerto Rico Trench a part of the Pacific that has bulged into the Atlantic...
When Woods Hole scientists took a closer look at the Trench, they found by echo sounding that its north wall is scored by fractures where deep-down rock seemed to be freshly exposed. Photographs showed the rock too, but bringing it to the surface was no easy task. Any sort of dredging in deep water is difficult; pulling a dredge among rocks and crags at the end of many miles of cable looked almost impossible...
