THE WIRELESS TELEPHONE

The rapid development of the wireless telephone is one of the romances of the war. In 1914 the wireless telephone was still in the experimental stage ami' was regarded as a kind of promising side-line to wireless telegraphy. But when the aeroplane began to be largely used for reconnaissance and for directing artillery fire, tie demand for some more easy and flexible mode of communication from the air to the land became urgent. British inventors responded magnificently to the call, and the crude apparatus of 1914 became rapidly perfected so that it could be relied upon in speaking between aeroplanes and land stations up to fifteen miles and beyond. Owing to'the necessities of secrecy very little was known to' the public about the improvements which had been effected, but their extent may l>e judged by the generous tribute paid by the director of an American electricai company which had been engaged on the same field. He has stated that British wireless telephones were better, '<a range and reliability, than, any which had been produced elsewhere. In the dedevelopment of electric cooking m Great less telephony, as well as wireless telegraphy, is likely to play an important part, since the safety of a service depends upon maintaining contact with aerodromes and aeroplanes, but aviation is far from being the only field of application The wireless te'ephone may supplement the newspaper as a means of international communication. As was pointed out by a leading British man of science, Mr. Campbell Swimonf F.R.S., a speech delivered in London may be heard simultaneously in Calcutta. -Cairo. Paris, Petrogradj New York, and on Vessels in mid-ocean; and by the use of loud-speaking telephones iaree audiences iray listen to the transmitted tone.', as if they were being addressed by the original speaker.
