WIRELESS FOR EVERYONE.

, Guglielino Marconi. the famous scientist, contributes a signed article to the | Nuovo Giornale of Florence on the imminent revolution in wireless communication . , Writing'of • wireless, telephony., Signor i Marconi announces that within the present year vocal communications transmitted without wires will replace the cumbrous system of to-day. He says: "Remarkable economic advantages will follow tliis, because it will dispense altogether with the cost involved in apparatus and the maintenance of lines—not to speak of the utter 'elimination of interruption now so frequent through the effects of bad weather and the occasional isolation of entire regions in conseI quenee of snowfalls. ..It is ,a curious | phenomenon that, whilst the most pro-' (.g-ressivo- peoples'-of Western Europe j have not yet contrived to adopt wireless ■ telephony on an essentially commercial i basis, China the most retrograde | among nations—is making daily usc-of ; the wireless telephone for communicai tions between•urban centres and rural districts which have not-h'een linked up [with the ordinary telephone system. America stands in the forefront of progress, its inventors having shown themselves capable of producing a really practical instrument for transmitting the human voice by means of electric waves. To-day we cannot concentrate the expansion of energy within a limited sector of .the circle so as to reach the furthest distance; but _ eventually science will find, a way of directing vlectric energy without wires- in an absolutely straight line. The result will lie less expenditure of energy for short distarices, and hence, less expense for messages. Once directive control lias been established, we shall undoubtedly be able, by means of powerful machines, to gird the whole world with waves of electric energy without wires simple pressing of a finger upon a transmitting buttou." •

t Turning to the subject of wireless I. telegraphy. . Signqr Marconi refers to : the notable developments inspired by the great war. He describes a marvellous radio-telegraphic receiver no bigger than gramophone, by .means of which—without any other wonted communication with the atmospherehe. is* receiving- all "day. long in -his study every s<jrajv of wireless news sent to the European Press. He says that very 'shortly, with an instrument of this kind, biinkc-rs, politicians.. and business men in general will, lie able from miiiuto to .minute Ho keep themselves in contact -with.. lioth hemispheres. He adds: "Yerv soon, too, that miserable licking machine whereon all newspaper offices -depend will yield place to this linghtv invention—whieii is apt lor newrt-seiidmg. news-receiv-mtr. and .simultaneous communication with iinv number of: receiving stations.In this why the journals will bis able "ttf ;wipo .<)ut ciJ!isjdferable costs; besides saving, the great -.loss of time now nc: fe«sit\ !oi dispiuhnur epii't mi 4 ■ sages..
