No hint of it was even flashed through space by that wireless telegraphy which has existed between kin souls ever since men and women contrived to raise human affinities to a plane not far removed from the divine. He had small store of German, but he knew enough to be perplexed by the way in which Helen's driver expressed "beautiful thanks" for her gift.
He had seen Indian telegraphy before, and had learned to comprehend a great deal of those mysterious signs and signals by which news is carried across mountain and prairie with incredible speed. He had ridden his fleet mustang to death to head off some of these telegrams, and yet in every case the Indians, by some trickery unexplained to him, had outsped him.
Our policy of isolation corresponded with the situation as it existed a hundred years ago, but not with the situation as it exists to-day and as it has existed for some years past. We no longer occupy a "detached and distant situation." Steam and electricity, the cable and wireless telegraphy have overcome the intervening space and made us the close neighbors of Europe.
The greater the fires, the greater were the vibrations and consequently they carried farther to the receiver, which was the eye. If a signal is to be sent a great distance by light the source of that light must be correspondingly powerful in order to disturb the ether sufficiently. The same principle holds good in wireless telegraphy.
So it came about that he was probably the last person on board to hear the news that wireless telegraphy was bringing to the airship in throbs and fragments of a great naval battle in progress in mid-Atlantic. He learnt it at last from Kurt. Kurt came in with a general air of ignoring Bert, but muttering to himself in English nevertheless. "Stupendous!" Bert heard him say.
As usual, he listened with that wonderfully luminous face of his and that close attention to the discourse, which, like the cable-ships, ran out unseen telegraphy of sympathy.
To-day no large city in America is without a service of this character, but its function was sharply limited by the introduction of the telephone. Returning to the automatic telegraph it is interesting to note that so long as Edison was associated with it as a supervising providence it did splendid work, which renders the later neglect of automatic or "rapid telegraphy" the more remarkable.
Although the Tarapai sheriff knew nothing about wireless telegraphy, he did understand some of the methods which savage tribes in many countries use in order to send news hundreds of miles; sometimes by a chain of drums stationed on the hill tops miles apart; or it may be by the waving of a red flag. "And I want to tell you, Frank," Mr.
This is the size of tube generally used by amateurs for long distance continuous wave telegraphy. A single tube will develop 2 to 3 amperes in your aerial. The filament takes a 10 volt current and a plate potential of 1,000 volts is needed. A tube socket to fit it costs $2.50 extra. The Aerial Ammeter. This should read to 5 amperes and the cost is $6.25. The Grid Leak Resistance.
He could only think that the secret telegraphy of his love had sent her messages of confidence. And yet he did not even know her name. The house was just such a one as he might have imagined to be her home beautiful, with the air of a longer family tradition than is commonly found in the Middle West unobtrusive but complete.
