Cablegram

“ For example, a cablegram from the Philippines to Nome, Alaska, will be transmitted by Continental Morse (commercial cable) from Manila to San Francisco, by American Morse (commercial land line) from San Francisco to Seattle, by Continental Morse (military cable) from Seattle to Valdez, by American Morse (military land line) from Valdez to Nulato and by Continental Morse (military radio) from Nulato to Nome. ”

“ As Barrat sipped his coffee and munched his rolls with the silent energy of a hungry man, the Colonel turned and strode up and down the terrace, pulling at his mustache and glancing sideways. When the Baron had lighted a cigarette and thrown himself back in his chair, Erhaupt halted and surveyed him in some anxiety.
"You have been gone over two weeks," he said. "I should like to see you accomplish as much in as short a time," growled the other. "You know Paris. You know how hard it is to get people to be serious there. I had the devil's own time at first. You got my cablegram?" ”

“ Have no more. Nor credit. Can not provision ship.
(signed) d’Alvarez, Admiral."
“Treasury empty. You used last money to buy ship. This is a war not a tea fight. Hurry over. Bombard San Sonate port. Then collect war indemnity.
(signed) Zelaya, President”
“Can’t sail without money.
(signed) d’Alvarez, Admiral.”
“Borrow. (signed) Zelaya, President.”
“No credit. (signed) d’Alvarez, Admiral.”
“Get money or credit somehow.
(signed) Zelaya, President.”
“How? (signed) d’Alvarez, Admiral.”
There had been no reply to his last cablegram. The gunboat had stopped taking on provisions. ”

“ If it had proved to be imperfect, all the labor spent upon it would have been lost. The electricians waited breathlessly for an answer. The clerk in the signal-house at Valentia was drowsy when their message came, and disbelieved his ears. Many disinterested people, and even some of the promoters of the cable, did not think it possible to recover a wire that had sunk in thousands of fathoms of water. But the clerk in the little station connected with the shore-end of the cable of 1865 suddenly found himself in communication with a vessel situated in the middle of the Atlantic. ”

“ In a recess of the room which I caused Sir Marcus Coverly to visit at the Red House, I placed this duplicate telephone; the false cable communicating with the instrument was attached to a plug in the wall above, but communicated with a gas cylinder in the adjoining room. In short, what appeared to be cable was in reality tubing and the act of taking the receiver from the hook released through the mouthpiece a sufficient quantity of L.K. Vapor to have asphyxiated a dozen men. ”

“ The best operators cannot send over thirty-five words per minute by hand, but a hundred and twenty words or more per minute can be transmitted by an automatic sender, and the recorder has been found on land lines and short cables to write off the message at this incredible speed. When we consider that every word is, on the average, composed of fifteen separate waves, we may better appreciate the rapidity with which the siphon can move. On an ordinary cable of about a thousand miles long, the working speed is about twenty words per minute. ”

“ Thank God the cable has been successfully laid and is in perfect working order. I am sure that no one will be as thankful to God as you and our dear children. Now we shall be a united family. We leave in about a week to recover the cable of last year. Please telegraph at once and write in full, and I shall receive your letters on my return here.
“On the 15th inst. I received through the cable from Valentia your message from Newport and Grace’s telegram from Newburg, and on the 22d inst. your telegraphic despatch of the 10th inst., and this moment your letter of the 12th inst. ”

“ On the 14th of September the cable dispatch was sent to the office of the Observatory at Washington, with orders to figure out the final consequences upon geographical locations. Two days afterwards the problem was all worked out. The Old World was notified of the results by cable and the New World by telegram. After this calculation had been published by thousands of papers, it was the only thing talked of in the great cities and everywhere. What will happen?
This was the question which everybody was asking at every point of the globe. ”

“ A twisted cable of telephone wire may, when each circuit is formed by diametrically opposite wires, be placed in the same tube with similar cables employed for telegraph purposes. The central wire of the cable may be used either as a telegraph line or as a telephone line having an earth return. Another method is to use powerful telephone transmitters and insensitive receivers ; that is to say, make the telephone currents so powerful that the telegraphic induced currents will be small in comparison, and use receivers so insensitive as to suit such currents. ”

“ The life and experiments of Morse are then pictured and the dramatic story of the invention and development of the telegraph is set forth. The submarine cable followed with the struggles of Field, the business executive, and Thomson, the inventor and scientific expert, which finally culminated in success when the Great Eastern landed a practical cable on the American coast. The early life of Alexander Graham Bell was full of color, and I have told the story of his patient investigations of human speech and hearing, which, finally culminated in a practical telephone. ”

“ Those who had leisure for sleep were able to dream about cable-laying and the terrible effects of too great a strain. The first question which such as these ask on awakening is about the cable, and on being informed that it is all right, satisfaction ensues until the appearance of breakfast, when it is presumed this feeling is intensified. For those who do not derive any particular pleasure from the mere asking of questions, the harmonious music made by the paying-out machine during its revolutions supplies the information. ”

“ Thus the carrying capacity of the wire is in practice nearly doubled, and recorders are busy writing at both ends of the cable at once, as if the messages came up out of the sea itself.
We have thus far followed out the recorder in its practical application to submarine telegraphy. Let us now regard it for a moment in its more philosophic aspect. We are at once struck with its self-dependence as a machine, and even its resemblance in some respects to a living creature. All its activity depends on the galvanic current. ”

“ After passing through such elaborate tests, all will be glad to see the final product of so much care and skill. As the long line begins to reel off from the great wheels and drums, we may examine it in its completed and more perfect form. It is only necessary to compare it with the cable laid in 1858, to show its immense superiority. A glance at the two as they appear on the preceding page will show that the cable had grown since first it was planted in the ocean, as if it were a living product of the sea. This growth had been in every part, from core to circumference. ”

“ Digital signals are transmitted as compressed data in the form of binary digits, or “bits.” (Id. ¶¶ 19–20, 38) . The number of bits that can be sent in a second is known as the “bitrate.” (Id. ¶ 41) . Digital signals allow for a greater variety in television programming—because more signals can be transmitted in the same space—as well as interactive services and, often, better audio and image quality than analog television. (Id. ¶¶ 39–42) . The RS-DVR would be offered as part of Cablevision’s digital cable service. ”

“ I feel that the toast which I have the honour to propose deserves a foremost place in the toasts of the day, and that you will heartily respond to it, namely, Success to the Telegraph Construction and Maintenance Company, for that Company has laid scores of cables since its formation, and has now successfully commenced, and will doubtless triumphantly complete, the laying of the cable which we have met to celebrate to-day—the fourth great enterprise, I may remark, which the Company has undertaken—the cable that is soon to connect India with England. ”

“ There was a strange, unnatural silence in the ship. Men paced the deck with soft and muffled{66} tread, speaking only in whispers, as if a loud or heavy footfall might snap the vital cord. So much had they grown to feel for the enterprise, that the cable seemed to them like a human creature, on whose fate they themselves hung, as if it were to decide their own destiny.
“There are some who will never forget that first night at sea. Perhaps the reaction from the excitement on shore made the impression the deeper. There are moments in life when everything comes back to us. ”

“ Facsimile of siphon recorder message. matic curb sender the cable is put to one or the other pole of the battery and then to the reverse pole for definite proportionate times during each signal. The cable is thus charged first positively and then negatively, or vice versa, for each signal. This method not only facilitates the discharge of the cable, and so accelerates the return of the index of the receiving instrument to zero, but provides the means of sending positive and negative currents into the cable at the proper times and for the proper intervals. ”

“ One can never be sure when the line may be unfit for duty. Sometimes from storms, sometimes from the assassination of the operators in wild districts through which the land wires pass, and sometimes from the destruction of lines out of pure mischief, the telegraph is often beaten by the mail.”
“There seems, indeed, much need for a cable direct,” said Sam, “which will make us independent of Turks, Persians, Arabs, and all the rest of them. By the way, how long is your cable?” ”

“ The ordinary double current cable key with two levers, was arranged with an additional lever in such a manner that while in ordinary use in the telegraph office, it could also be put in circuit with the chronometer and chronograph in the observatory, and a signal sent through the cable would have its time of sending registered on the chronograph. Ordinarily in speaking over a cable line, connection is made in such a way that the current sent does not pass through the recorder at the sending station, as a violent movement of the siphon would result. ”

“ The cable may run on a level—as when it spans some great gorge between two mountain peaks—or it may be strung up to any incline not too great to make precarious the grip of the grooved overhead wheels of the basket. I was not able to learn what this limit is, but I have never seen a cable run at an angle of over forty-five degrees. Wherever a cable does not form a single great span it has to be supported at varying intervals by running over steel towers to prevent its sagging too near the earth.
A teleferica has never more than its two terminal stations. ”

“ To make the telephone an annex of the post office or the telegraph has become absurd. There are now in the whole world very nearly as many messages sent by telephone as by letter; and there are THIRTY-TWO TIMES as many telephone calls as telegrams. In the United States, the telephone has grown to be the big brother of the telegraph. It has six times the net earnings and eight times the wire. And it transmits as many messages as the combined total of telegrams, letters, and railroad passengers. ”

“ Now that we have reached the tail of the cable excitement, let us propound a simple query: What have we gained by all this frenzy beyond the glorification of one or two individuals, who have suddenly discovered themselves to be great? We have foolishly spent a large sum of money—we have made an exhibition of ourselves, and have no equivalent to show in exchange for our funds and our honor. By the tail of the cable hangs a curious tale indeed. ”

“ The knob on the lid is made of silver and is decorated with an anchor and a rope in silver. No maker’s mark is discernible.
While the public adulation was at its peak the cable suddenly stopped working. Immediately public opinion changed and Field was accused of being a fake. He suffered severe business reverses and in 1860 went into bankruptcy. The outbreak of the Civil War prevented any further activity on the cable until 1865. Field engaged the world’s largest steamer, the Great Eastern, to make the next attempt. ”

“ Since that time great improvements have been made until now it is difficult to recognize in the delicate mechanisms of the relay, key, sounder, duplex, quad, and multiplex, the principle first promulgated in the old Morse register. Its influence was at once felt in all walks of life; it was an art to be an expert telegrapher. Keeping pace with the strides of advancing civilization, the telegraph has spread its slender wires, until now almost the entire world is connected by its magnetism. ”

“ The observers leaving their assistants to take care of the chronographs, go to the respective telegraph offices, and all being ready, the observer A taps his key. This sends an impulse through the cable, which appears on A's recorder, as a violent jump or kick of the siphon. On B's recorder it is registered as a deflection like the ordinary dot or dash, at the same instant is recorded on A's chronograph the time of sending. As soon as B sees the signal on his recorder, he taps his key also registering the signals on both recorders and on his chronograph. ”

“ The famous steamer Great Eastern took the cable, but after going some 1,200 miles, the great vessel gave a lurch that broke the cable and an attempt to grapple it was unsuccessful. In 1866, however, a cable was successfully laid. A private citizen seldom receives such honors as was showered on Mr. Field, in 1866, when Europe and America realized that largely through the exertions of one man, they were joined by the Atlantic cable. He had pushed a vast project to a successful consummation in spite of incredulity, ridicule, indifference and strenuous opposition. ”
