Device  to  Supplant  News  Tickers
By  GUGLIELMO  MARCONI

    Notwithstanding that the transmission of electric force by wireless radiation is already one of the indispensable factors in the world's social and commercial economy, the science of wireless transmission is yet in its infancy. The marvels which remain to be achieved in the field of electric radiation pass the compass of the human imagination.
    During the past five years of war, little apparent progress was made, so far as the layman is concerned, in the development of commercial wireless. The layman, however, is totally unaware of what has been going on behind the scenes in the wireless world since 1914, for the reason that all new inventions have been commandeered by the various belligerent governments and held scrupulously secret for fear improvement might be seized upon by enemy interests to further military plans. automobile ticker

SMALL  BUT  MARVELOUS.

    I have in my home, for instance, a marvelous little contrivance, no bigger than the ordinary phonograph, which is a self-contained wireless receiving set, so accurate and so sensitive that, without a single exterior or other solid communication with the outer atmosphere it registers for me the entire important wireless activity of the world and brings into my own sitting room the wireless press news of all Europe. With an instrument similar to this bankers, brokers and business men generally will be able to keep in touch with the entire world's activity from minute to minute.
    The conventional news ticker, upon which all newspaper offices are dependent to-day will shortly be supplemented by this powerful adjunct to news transmission, which permits a single operator at the sending point to communicate with an indefinite number of receiving stations simultaneously, thus cutting down the tremendous expense and loss of time entailed in sending separate messages over as many wires as there are receiving points.

EDUCATIONAL  EFFECT.

    It is difficult to conceive of the tremendous educational effect of this appliance along when its possibilities are fully developed, as they will be very shortly, to such a point that, in conjunction with an automatic ticker, the day's news from the four corners of the earth will be registered in clear language without the necessity of a Morse code expert to handle the receiving end.
    With such a wireless receiving set installed in every public school, university and library throughout the civilized world the average interest in public and international affairs will be tremendously augmented and there will no longer be any reason why the school boy and girl should not be as well informed in matters of current importance and at no expense, as the most inveterate newspaper reader.
    The war contributed a notable impulse to the development of wireless telephony. America was particularly forward in this field and succeeded, through the genius of its inventors and experts, in producing a really practical apparatus for the transmission of the human voice over considerable distances by means of wireless electric waves.

CHINA  USES  RADIOPHONE.

    It is a curious fact that while the most progressive nations of the western hemisphere have not adopted the wireless telephone on a commercial basis and are still experimenting on possible improvements, China, most backward of all the great nations, is making current use of the wireless telephone as a means of communication between outlying towns and villages which have not as yet been connected with the ordinary telephone system
    Within 50 years wireless voice communication will in all likelihood supplant the present cumbersome system and materially cut down the expense of wire laying and upkeep and the inconvenience of broken communication which today isolates whole regions every winter following the damage wrought by rain and sleet.
    In the past five years of military secrecy we have been making progress in the problem of directing wireless energy. Hitherto electric energy transmitted through the air has spread out with equal intensity in all directions, thus dispensing the total force employed over a vast area and limiting the distances at which communication was possible.

REACHING  FARTHER.

    Today we are able to concentrate the energy expended to a limited sector of the circle and thus reach far greater distances than ever before attempted. Eventually science will find a way to send wireless electric waves along an absolutely straight line. The result will be far less expenditure of power for short distances and therefore less expense involved in wireless communication. And there is nothing to prove that when direction control has been completely established we shall not be able, with a powerful sending set, to girdle the entire world with wireless waves by the pressure of a single finger on a transmitting key.
