WIRELESS TELEPHONY

<f»01l OUR' OWN COMBfPOfB INT.) SYDNEY, sth July. ' ; Such progress has been made in wine* less telephony in Australia of late that those who havo been following its de* velopment predict that it will be hi commercial use before many years h«v» passed, and that it will eventually super*" sede wireless telegraphy. Almost daily after the wireless st»» tious have finished their" night's work, which is somewhere about la.m. or 2' a.m., the Melbourne radio station, indulges in a little wireless telephony practice, and gramophone records '. and the human voice are "despatched" into the ether. Amateurs 1200 miles away who possess wireless telegraphy receive ing sets have frequently heard the strains .of music from .Melbourne; "aiid even as far away as Townsville. which, of course, is a powerful rstation,'. the records have been heard quite clearly/ It ljae been demonstrated.-, that ...the human voice is not so,easy to transmit, as"music for every word lias a different: vibration, bht portions of speeches have been picked up at the distances men' tioned. A more remarkable incident "occurred recently, when the words used in an experiment by a person communicating with 'the wireless office in Melbourne over a land line, and transmitted by wireless telephony, were heard in Bris-' bane. " Unfortunately wireless developments in Australia are hampered -by senseless restrictions imposed by the Federal Government—restrictions that . are ; much more severe eveu than those in force >in England. Despite this, the wonderful science is developing in the Common, wealth. In regard to wireless telegraphy, the suggestion has just been put forward by an important authority, that every boy should be taught to learn the Morse code.
