WIRELESS TELEPHONY

RAPID DEVELOPMENTS. DANGERS OF INTERCEPTION. A NEW COMMERCIAL USE. (Press Association —By Telegraph—Copyright) VIENNA, January 9. A correspondent mentions a new instance of interception of the AngloAmerican telephoning. The owner of a three-valve set, occupying a house in a noisy street in the centre of the city, tuned in and heard every word, and even passed on part of the conversation to a local newspaper by placing the receiver of his set against the mouthpiece of a telephone connected with the newspaper. Marconi, in conjunction with the Austrian Broadcasting Company, is inaugurating an Austro-German wireless transmission of photographs of bills of exchange. It is expected that the system will shortly be extended to Britain. — The Times.

OTTAWA TO ENGLAND. NEW INTER-EMPIRE PROJECT. BEAM RADIO SYSTEM USED. OTTAWA, January 9. (Received Jan. 10, at 8.20 p.m.) The Empire wireless telephone was connected between Ottawa and England to-day over the Beam radio system from England to Drummondville, in Quebec, to which Ottawa is connected by land wire. Several conversations were conducted between the two countries, the distance being 3500 miles. These tests are not connected with the radiophone inaugurated between New York and London, and foreshadows the opening of direct telephone communication to all parts of the Empire. It is a new distinct interEmpire project, which it is hoped to carry out through the Marconi Beam system.— A. and N.Z. Cable.

ACROSS THE ATLANTIC. THREE COLUMNS OP NEWS. LONDON, January 9. (Received Jan. 10, at 8.5 p.m.) The first newspaper matter received by Transatlantic wireless telephony from New York was published in the Daily Telegraph, occupying three columns Pew calls were made to-day. Those using the system found conditions remarkably suitable. Reports come from various parts of the country of amateurs overhearing the conversations. The Post Office admits that it is unable yet to guarantee the same secrecy as with a telephone, but it denies that an entire conversation can be picked up.—A. and N.Z. Cable.
