     summary: The companies began to place their wires underground, and Vail saw to it that the experiments with coverings for telephone wires were continued. While working and waiting and saving, Morse conceived the idea of laying telegraph wires beneath the water.

     summary: However, with incomparably higher frequencies, which we may yet find means to produce efficiently, and provided that electric impulses of such high frequencies could be transmitted through a conductor, the electrical characteristics of the brush discharge would completely vanish--no spark would pass, no shock would be felt--yet we would still have to deal with an _electric_ phenomenon, but in the broad, modern interpretation of the word. But on the whole I find it preferable when using such high frequencies to employ only one electrode and one connecting wire.

       title: Hertzian Wave Wireless Telegraphy

      flesch: 53
     summary: The practical problem of electric wave wireless telegraphy, which has been variously called Hertzian wave telegraphy, Marconi telegraphy, or spark telegraphy (_Funkentelegraphie_), is that of the production of an effect called an electric wave or train of electric waves, which can be sent out from one place, controlled, detected at another place, and interpreted into an alphabetic code. Hence it appeared probable that a service would be rendered by an endeavour to present an account of the present condition of electric wave telegraphy in a manner acceptable to those unversed in the advanced technicalities of the subject, but acquainted at least with the elements of electrical science.
