TELEPHONY WITHOUT WIRES.

POSSIBILITY OF TALKING TO ' AMERICA. London, July 20. Wireless telephony is at last an established fact, both scientifically and commercially. A director of the Amalgamated Radio-Telegraphy Company told a press representative that his company is ready to take orders for the installation of a wireless telephony system to cover a distance up to twentyfive miles, over fairly flat land or over water. "Last Monday," he said, "I spoke in our laboratory at Berlin to a temporary laboratory which we had erected some seven miles away from that city, and that was not under the best conditions, because the aerial (or wire) at the temporary station was suspended between two factory shafts instead of the usual masts. "From experiments which we have been conducting in Berlin, we arc able to guarantee perfect communication by wireless telephony over twenty-five miles if not too hilly country. "The inventor of the continuous undamped wave, by which means only is wireless telephony made possible, was M. Valdemar Poulsen, a noted Danish electrical engineer. About eight months ago we bought M. Poulsen's invention, together with all his plant and experimental stations, and we have secured patents for the whole world with the exception of the United biatcs. '•We are now converting our stations at Oxford and Cambridge into wireless telephony stations on the Poulsen system, and when the work is completed, which will proliably be in six weeks' time, we shall begin to experiment there. 1 am confident that we shall be successful in establishing wireless telephonic communication over the sixty miles which separate the two university towns and I do not hesitate to express my conviction that in a few years' time we shall be able to speak across the Atlantic."
