AID TO SHIPS’ SAFETY
ECHO-SOUNDING DEVICE STRIKING TRIBUTE PAID Times Cable Reed. 9.5 a.m. LONDON, Monday. “Echo-sounding as an aid to navigation is making rapid progress ia the British Mercantile Marine,” says the naval correspondent of “The Times.” The British Admiralty pioneered the new system by installing surveying vessels; but difficulty was encountered in cutting the necessary holes in existing ships. The instruments are now built in the shell of new ships, without perforation. Fifty British merchantmen have been fitted inside two years. A striking tribute to the device comes from the navigating officer of the cruiser Australia. Referring especially to navigation in the vicinity of Halifax and the St. Lawrence, he said echo sounding had proved of the utmost use, adding 25 per cent, to a ship’s safety in thick weather in pilotage waters.
