HUMAN VOICE TRANSMISSION. CORNWALL TO SYDNEY. A GREAT ACHIEVEMENT. (Receiver I 9 a.m.) SYDNEY, This Day. Mr E. T. Fisk, managing director of Amalgamated Wireless of Australasia, announced that the human voice was successfully transmitted from Poldliu, Cornwall, England, to Vaucluse, Sydney, on Sunday, the first successful wireless telephonic communication between England and Australia. —A. and N.Z.

THE BEAM SYSTEM. KNOWS NO BOUNDS. "ANYWHERE TO ANYWHERE." (Received 9 a.m.) LONDON, .1 une 3. The "Daily Telegraph," in an interview with the Chevalier Marconi, confirmed the successful experiment in wireless telephony between England and Aussalia. He said: "My system was not employed. It is entirely because the arrangements are not completed, the system has been used without a beam; but nevertheless without a beam it has been possible to do what has never been done before. Speech was transmitted quite clearly and 1 am convinced it would be quite easy to conduct conversations between England and Australia; and if it is possible to conduct such conversations it will be practical, by the beam system, from anywhere to anywhere. There will be no distance in the future over which we cannot telephone." The interviewer asked the Chevalier Marconi if it would be correct to say, "Your new system was used without a beam ?" Signor Marconi replied: "Yes, ex* perimentally. The new system comprises something more than a beam. That something we ivon't speak about at present. An earlier successful experiment between Ireland and Melbourne was telegraphy, not telephony." —A. and N.Z.

NO SPECIAL DIRECTION. HEARD IN MONTREAL. (Received 2.30 p.m.) LONDON, June 4. Mr Marconi, at a conference with Press representatives, said that tlie experiments with. Australia were conducted without utilising a beam, although he employed many features of that system. The electrical wave which carried the voice was not directed to any particular part of the globe. The messages were also heard distinctly in Montreal by a simple receiver; in fact, any fairly reasonable receiver could have picked them up. The arrangements here and in Aust-'alif. were not elaborate, but purely experimental. The transmitting power was approximately 20 kilowatts. He was not prepared at present to disclose the wave lengths. No doubt when the beam system was utilised with the same wave length the results would be most satisfactory. It would be available for high-speed telegraphy between "Engl ind and Australia or telephony when required. They would certainly follow up this success. Fis expectations were mostly biased on the beam system, with which one tenth of a kilowatt would give as satisfactory results as 20 by non-directional wireless. Mr Godfrey Isaacs stated: "We are prepared to erect stations for highspeed telegraphy and telephony here and in other parts of the world the moment, facility is accorded.''''—A. and N.Z.
