19,000 Miles by Phone

New World Record A WORLD'S record in long-distance y telephony was established recently/ by means. of a call from Christchurch, via Sydney and London, to Buenos Aires. The test was made with a view to ascertaining the commercial efficiency of the circuit over this route. From Christchurch to Wellington the gap was, of course, bridged by ordinary telephone lines, and from Wellington to Sydney the trans-Tasman wireless service was used. The next link was the A.W.A. radiophone to London, and from there the trans-Atlantic wireless telephone to Buenos Aires completed the talk. The technical operators report that voices, not only from each end of the circuit, but at every point between, were marvellously clear. Recently a world record for long-dis-tance radio telephony was created by bridging the distance of 17,000 miles between Sydney and Valparaiso, but the conversation from Christchurch to Buenos Aires constitutes a new record of 19.000 miles As the time oeeupied by the voice travelling over such a circuit is only about one-eighth of a second, persons conversing do not ndtice any lag in the words spoken.
