Dangers of Navigation
Locating Icebergs
JLFFORTS are still being made to devise a practical iceberg finder that will give infallible warning to an ocean liner of the presence of the danger. Radio has been of some aid in preventing a repetition of a disaster such as that which caused the loss of the Titanic some years ago, but even this medium is not entirely successful. coast-guard ice patrols, by eans of radio, are able to warn vessels of the presence of icebergs they have located, but -no instrument has been found sufficiently practical to pay for its installation on liners themselves. Sounding apparatus has been made which will detect icebergs a mile or so distant, but such apparatus is not very successful because of the speed of modern ships and the lack of accuracy in making distance measurements. The development of the radio compass, or directional-finder, however, now enables rescue ships to reach a boat in distress much more quickly than was possible at the time of the Titanic disaster.
