Show I To Destroy Submarines U1 RANCE and England have begun to breathe easier when contemplating the submarine. A New Yorker named William Dubiller, working with Professor Tissot of the French Academy, says they have invented a sea telephone by which a submarine in motion anywhere within seventy-five seventy-five miles can be located and a destroyer sent to sink it; that from the deck of a ship on which he came out of Boulogne harbor, he saw a submarine, sub-marine, located and destroyed. It is a small instrument, Dut it records the vibration of the propeller of a submarine and also its speed and the direction it is m'oving in. He says the French harbors and coast are protected by them and that n they are being installed around the coasts of the u British isles. J The English claim that they have invented a I new type of mine for destroying submarines, and a new and very swift ocean motor boat to over take and annihilate submarines and that they have already destroyed more than fifty German ' submarines. |
