Wonders of Ship Guidance by Electricity Philadelphia, Nov. 28.
Admiral W. H. Bullard, Director of Naval Communication Service, in a paper read before the Franklin Institute here, said wireless telegraphy is making navigation simple and safe.
"There will be a time when ships will be without chronometers, and will be in constant wireless touch with New York until they reach the British channel," said Admiral Bullard. This is not a dream; it is near at hand.
"By means of the compass a ship can get her bearings when she calls for it, anywhere along the coast of the United States. This instrument has already saved ships which were heading straight for the shore.
"The depth of water under the chip can now be accurately determined by the hydro-phone, which works on the reflexion from the ocean bottom of the sound of the ship's propel By this device shallow water can be avoided, and even the proximity of icebergs detected. Ships also can communicate with each other by wnderwater waves, sent out by oscillators.
/Ry means of a cable laid along the bottom of New York channel and energized with current, a pilot, blindfolded, guided a destroyer safely to port, never getting more than 50 yards from the cable, The waves sent out by the cable were detected in telephone receivers, one fon each ear, telling him whether he was to right or left of the guiding cable.
"Hurricanes can be detected by sensitive radio telephones, and overt the general direction of storms, are felt on wireless receiving apparatus. The tinie is now sent broadcast by coastal stations, and by the time given for certain longitudes the ship can tell its location. Weather warnings and location of wrecks, derelicts and icebergs are also given out."—Reuter.
