Show HOW WOULD YOU FIGHT A SUBMARINE? American Inventive genius may win glory and relievo a nation of much suspense by pointing out how the submarine sub-marine menace which now confronts England can be ended. The difficulties difficul-ties to be overcome seem almost insurmountable. in-surmountable. The submarine exposes ex-poses a little tube, called a periscope, which cannot be seen at a distance greater than a few hundred feet. Through reflecting glasses in this tube, the officer of tho submerged vessel ves-sel scans the horizon. If danger is In sight, the undersea craft entirely disappears; if an unsuspecting warship war-ship presents an inviting target or i an unprotected merchant ship is near, , Lho submarine launches a torpedo and, if the torpedo strikes home, whether dreadnaught or clipper, the ship goes down. How to meet that method of naval warfare is today puzzling many mind?, and the one that evolves a success ful plan to safeguard ships against the submarine will be in a position to exact not only money, but enduring fame. There are ships equipped with electric elec-tric diaphragms, or ears, below the water line, which by catching the pul- satlons of a submarine engine, servo to warn the crew of the presence of the undersea craft, but they cannot be of service except at short ranpo and, therefore, are not a complete protection. The hydroplane is said to bo able to detect a submerged submarine, sub-marine, when directly over the submersible, sub-mersible, but so far the aerial has failed as a guard. Who can suggest a weapon with which to fight the undersea craft9 Some day that question may be put direct to the American people, the answer to which may mean much to our own shipping and national security. |
