WIRELESS TELEGRAPHY.

THE MARCONI CONTRACT. London, March 13. In the -House of Commons, Captain C. W. Norton, in reply to a question on the subject of the Marconi Committee’s decision, said the Post Office was prepared to grant long distance licenses to any' British wireless company on proof of financial stability and technical competency. NEW WIRELESS SYSTEM. Some attention is being directed in England to the Kelway sound-locat-ing wireless system, which it is claimed would enable vessels to be safeguarded against the possibility of running ashore or colliding in thick weather by means of communication from ship to shore, and from ship to ship. The system involves the instantaneous sending off of Hertzian waves, which ring a bell in the chart room of the vessel provided with a simple receiver, together with the firing of an explosive fog signal. The interval between the receipt of the bell message and the explosion indicates exactly the distance of the signaller. The signals and explosions are repeated every three minutes. On a second series being received the navigator knows instantly by a simple calculation, based on the speed of his ship, and made exact by the use of the telemeter, not only his distance from the signalling station, but also the exact direction in which it lies off his course. The signals, it is claimed, can easily be sent over a radius of at least sixty miles, and Mr. C. E. Kelway, the inventor, advocates the system'for use at navigation centres, so that vessels in crowded and dangerous shipping ways would be in no danger of running ashore. The apparatus can, it is stated, be carried and manipulated without difficulty, and other ships receiving urgent calls for assistance would be able instantly to make for the exact part of the seas where their services are required. Mr. Kelway asserts that, if his system had been adopted, the Californian would have been able to reach the Titanic speedily, and have saved nearly everyone on board.
