Everyone laughed at the idea of women signalling, but to-day the members are recognized officially, one holding an important appointment in the college of wireless telegraphy.

But no strictly electromagnetic apparatus for telegraphic signalling was put to successful use until 1836, when, in England, Charles Wheatstone, who is commonly regarded as the first inventor of practical electric telegraphy, constructed an apparatus whereby thirty signals were transmitted through nearly four miles of wire.

For fire-alarms and for all sorts of purposes, domestic telegraphy is part and parcel of the nature of an American, and the result was that when the telephone was brought to him, he adopted it with avidity.

End-of-course test in basic telegraphy and telephony.

He stated that he wished to draw special attention to increasing the safety of navigation against storms, fogs, fire, and collisions with wrecks, icebergs, or vessels, and recommending the development of maritime telegraphy.

He further adds how the Chinese, whose, "chronicles antedate the historic records of all other nations, seem to have had a simple but complete mode of communicating ideas by means of florigraphic signs;" whereas, "the monuments of the old Assyrian and Egyptian races bear upon their venerable surfaces a code of floral telegraphy whose hieroglyphical meaning is veiled or but dimly guessed at in our day.

No one else was wagging and waving in that way: a gestureless mute telegraphy seemed to pass between the other boxes.

All the officers of the different fleets, seated near them, had at their disposition cannon, ram, torpedo, great speed and aerial telegraphy.

" From that time forward Hubbard took every occasion to encourage Bell to carry forward his experiments in musical telegraphy.

There was a throb of passionate joy in the ranks when this eulogium reached the men, for the words were hardly spoken when they were known in every company by that mysterious telegraphy which makes the human body a conductor swift as an electric wire among large masses of men.

It can be shown by the testimony and experience of those most eminent in the science and practice of oceanic telegraphy, that neither length of distance, within the limits with which the Atlantic Company has to deal, nor depth of water, is any insuperable impediment to efficient communication by such improved conductors of electricity as are now proposed to be laid down.

With preternatural vigilance she watched each movement of the Caïd, who never spoke to her, looked at her, or made her the slightest perceptible sign, but whose least wish she instantly divined, refilling his tea-cup, passing the plates of sweets, or removing our empty glasses, in obedience to some secret telegraphy on which her whole being hung.

These gutta-percha-covered wires were used for underground telegraphy both in England and on the Continent.

The improvement of navigation, he said, meant an international code of police to improve police rules of navigation; an international code of universal telegraphy for navigation; an international office of meteorology and navigation to collect the studies; experiments on the weather, on the sea, on the casualties; and the discovery by experiment of new apparatus and appliances to diminish maritime disaster.

This little telegraphy was all we could manage; we were as far apart as if the Atlantic were between us.

Submarine telegraphy was in its infancy, and aërial telegraphy had scarcely outgrown its swaddling-clothes.

Automatic telegraphy, 53, 105, 266. B Baltimore-Washington Telegraph Line, 86.

But no strictly electromagnetic apparatus for telegraphic signalling was put to successful use until 1836, when, in England, Charles Wheatstone, who is commonly regarded as the first inventor of practical electric telegraphy, constructed an apparatus whereby thirty signals were transmitted through nearly four miles of wire.

And so it was the reading of the discovery of Hertz that started the boy on the train of thought and the series of experiments that ended with practical, everyday telegraphy without the use of wires.
