...tons admitted by Britain. At the same time Germany declared that only three U-boats had been sunk. Britain and France each replied with a report of another U-boat sunk, bringing the number claimed by them to more than 20 or nearly one-third of the known Nazi undersea fleet. From a smashed U-boat found on Goodwin Sands, British divers took more than 50 bodies. Score for the war's eighth week of all shipping sunk by German mines and torpedoes: six vessels, 28,677 tons. Score for the Allied blockade of contraband goods was not given...
...foreign submarines in U. S. waters had been Lieut.-Commander Cooke's Commander in Chief, Franklin Roosevelt (who was seeing submersibles as late as Oct. 7 off Miami). Last week the President cited no visiting submarines, but he made submarine news of the first importance. By denying belligerent undersea boats right of entry to U. S. ports, save in dire emergency, he drew a significant distinction between prospective German raiders and the surface warships and armed merchantmen of Great Britain and France...
Since the loss of the submarine S-4 in 1927, Commander Momsen had been devoting his energies to experiment in undersea rescue work; during this time he had developed his famous "Momsen lung," a last-chance device which would have been used in rescuing the crew of the Squalus one at a time, had the rescue chamber failed...
...September 1920, the 5-5 sank off the Delaware Capes. Evidence was that she, too, was flooded through the pipes which supply a subrftarine's Diesel engines and crew with air when on the surface. (Undersea, battery-driven motors propel a submarine, stored air supplies the crew.) A Board of Inquiry thereafter recommended steps to find out whether an automatic, interlocking control could be developed so that when air valves were open, the ballast tanks which weight a submarine with water and make it dive could not be filled...
Submarine Canyons. Modern methods of exploring the ocean bottom by echo-sounding have disclosed several huge undersea canyons. One of these submerged gorges, lying off the Hudson River's mouth, is 130 miles long and its lower end lies under 7,500 ft. of Atlantic Ocean. One theory has it that submarine canyons were cut during the Glacial Age by surface rivers. This could have occurred only if the sea level was then nearly two miles lower than it is now - a presumption difficult to account for, even allowing for water drawn into the great Glacial Age ice sheets...
