Wireless Telegraphy.

fl wo articles in another column are fascinating reading. One from our Paris correspondent tells the story of the scientific success in the measurement of time which has obtained for the Eiffel Tower a free pardon for the unpardonable sin—in Paris at all events ugliness. The other translated for us from the German, narrates the marvellous discovery by which wireless telegraphy is made absolutely safe against all possible prying and all conceivable inquisitiveness. It is the invention of Capt. Hovland, of the Norwegian Navy, who has made a great record. The marvel of ingenuity here is a cynher which is sent through space to Us destination, which keeps up its incognito all the way, and on arrival automatically translates itself into ordinary (printed) letter for the information of the person entitled to receive it, and for him alone. All that is necessary is for two stations to agree on is a letter combination, and after that a simple regulator keeps the two instruments in tune within negligeable limits of error. It will be seen that neither Marconi, nor de Forrest, nor Yaldemar Paulsen, nor the Telefunken people possess this device. It is the invention of the Norwegian officer, and may be applied to any system. We trust the New Zealand Government will display its usual promptitude in the provision of an installation. ‘
