WIRELESS COMMUNICATION.
Communication hy Hertzian waves is tlie only practical method of transmitting messages beyond the horizon, to recipients whoso position is nob known or whose position is continually changing. Hence, wireless telegraphy; and telephony have no rivals, for the purpose of communicating with distant ships, aeroplanes, surveyors and explorers. Again, it is characteristic of wireless or radio communication that its waves tend to spread equally in all directions and thus the messages can be made available to all who possess the necessary apparatus. Exmples of this quality are seen in the modern art of radio broadcasting and in the wireless call for help of a ship in distress. Hero again, wireless has no competitor. —From P. R.
