  Telegraph \Tel"e*graph\, n. [Gr. ? far, far off (cf. Lith. toli)
     + -graph: cf. F. t['e]l['e]graphe. See Graphic.]
     An apparatus, or a process, for communicating intelligence
     rapidly between distant points, especially by means of
     preconcerted visible or audible signals representing words or
     ideas, or by means of words and signs, transmitted by
     electrical action.
     [1913 Webster]
     Note: The instruments used are classed as indicator,
           type-printing, symbol-printing, or chemical-printing
           telegraphs, according as the intelligence is given by
           the movements of a pointer or indicator, as in Cooke &
           Wheatstone's (the form commonly used in England), or by
           impressing, on a fillet of paper, letters from types,
           as in House's and Hughe's, or dots and marks from a
           sharp point moved by a magnet, as in Morse's, or
           symbols produced by electro-chemical action, as in
           Bain's. In the offices in the United States the
           recording instrument is now little used, the receiving
           operator reading by ear the combinations of long and
           short intervals of sound produced by the armature of an
           electro-magnet as it is put in motion by the opening
           and breaking of the circuit, which motion, in
           registering instruments, traces upon a ribbon of paper
           the lines and dots used to represent the letters of the
           alphabet. See Illustration in Appendix, and Morse
           [1913 Webster]
     Note: In 1837, Samuel F. B. Morse, an American artist,
           devised a working electric telegraph, based on a rough
           knowledge of electrical circuits, electromagnetic
           induction coils, and a scheme to encode alphabetic
           letters. He and his collaborators and backers
           campaigned for years before persuading the federal
           government to fund a demonstration. Finally, on May 24,
           1844, they sent the first official long-distance
           telegraphic message in Morse code, "What hath God
           wrought," through a copper wire strung between
           Washington, D.C., to Baltimore, Maryland. The phrase
           was taken from the Bible, Numbers 23:23. It had been
           suggested to Morse by Annie Ellworth, the young
           daughter of a friend. --Library of Congress, American
           Memories series
     Acoustic telegraph. See under Acoustic.
     Dial telegraph, a telegraph in which letters of the
        alphabet and numbers or other symbols are placed upon the
        border of a circular dial plate at each station, the
        apparatus being so arranged that the needle or index of
        the dial at the receiving station accurately copies the
        movements of that at the sending station.
     Electric telegraph, or Electro-magnetic telegraph, a
        telegraph in which an operator at one station causes words
        or signs to be made at another by means of a current of
        electricity, generated by a battery and transmitted over
        an intervening wire.
     Facsimile telegraph. See under Facsimile.
     Indicator telegraph. See under Indicator.
     Pan-telegraph, an electric telegraph by means of which a
        drawing or writing, as an autographic message, may be
        exactly reproduced at a distant station.
     Printing telegraph, an electric telegraph which
        automatically prints the message as it is received at a
        distant station, in letters, not signs.
     Signal telegraph, a telegraph in which preconcerted
        signals, made by a machine, or otherwise, at one station,
        are seen or heard and interpreted at another; a semaphore.
     Submarine telegraph cable, a telegraph cable laid under
        water to connect stations separated by a body of water.
     Telegraph cable, a telegraphic cable consisting of several
        conducting wires, inclosed by an insulating and protecting
        material, so as to bring the wires into compact compass
        for use on poles, or to form a strong cable impervious to
        water, to be laid under ground, as in a town or city, or
        under water, as in the ocean.
        [1913 Webster]
