Morse and his associates now had a telegraph which they were confident would prove a genuine success. But the great work of introducing this new wonder to the public, of overcoming indifference and skepticism, of securing financial support sufficient to erect a real line, still remained to be done. We shall see that this burden remained very largely upon Morse himself. Had Morse not been a forceful and able man of affairs as well as an inventor, the introduction of the telegraph might have been even longer delayed.
The new telegraph was exhibited in New York and Philadelphia without arousing popular appreciation. It was viewed as a scientific toy; few saw in it practical possibilities. Morse then took it to Washington and set up his instruments in the room of the Committee on Commerce of the House of Representatives in the Capitol. Here, as in earlier exhibitions, a majority of those who saw the apparatus in operation remained unconvinced of its ability to serve mankind. But Morse finally made a convert of the Hon. Francis O.J. Smith, chairman of the Committee on Commerce. Smith had previously been in correspondence with the inventor, and Morse had explained to him at length his belief that the Government should own the telegraph and control and operate it for the public good. He believed that the Government should be sufficiently interested to provide funds for an experimental line a hundred miles long. In return he was willing to promise the Government the first rights to purchase the invention at a reasonable price. Later he changed his request to a line of fifty miles, and estimated the cost of erection at $26,000.
Smith aided in educating the other members of his committee, and one day in February of 1838 he secured the attendance of the entire body at a test of the telegraph over ten miles of wire. The demonstration convinced them, and many were their expressions of wonder and amazement. One member remarked, "Time and space are now annihilated." As a result the committee reported a bill appropriating $30,000 for the erection of an experimental line between Washington and Baltimore. Smith's report was most enthusiastic in his praise of the invention. In fact, the Congressman became so much interested that he sought a share in the enterprise, and, securing it, resigned from Congress that he might devote his efforts to securing the passage of the bill and to acting as legal adviser. At this time the enterprise was divided into sixteen shares: Morse held nine; Smith, four; Alfred Vail, two; and Professor Gale, one. We see that Morse was a good enough business man to retain the control.
Wheatstone and others were developing their telegraphs in Europe, and Morse felt that it was high time to endeavor to secure foreign patents on his invention. Accompanied by Smith, he sailed for England in May, taking with him a new instrument provided by Vail. Arriving in London, they made application for a patent. They were opposed by Wheatstone and his associates, and could not secure even a hearing from the patent authorities. Morse strenuously insisted that his telegraph was radically different from Wheatstone's, laying especial emphasis on the fact that his recording instrument printed the message in permanent form, while Wheatstone's did not. Morse always placed great emphasis on the recording features of his apparatus, yet these features were destined to be discarded in America when his telegraph at last came into use.
With no recourse open to him but an appeal to Parliament, a long and expensive proceeding with little apparent possibility of success, Morse went to France, hoping for a more favorable reception. He found the French cordial and appreciative. French experts watched his tests and examined his apparatus, pronouncing his telegraph the best of all that had been devised. He received a patent, only to learn that to be effective the invention must be put in operation in France within two years, under the French patent law. Morse sought to establish his line in connection with a railway, as Wheatstone had established his in England, but was told that the telegraph must be a Government monopoly, and that no private parties could construct or operate. The Government would not act, and Morse found himself again defeated. Faring no better with other European governments, Morse decided to return to America to push the bill for an appropriation before Congress.
While Morse was in Europe gaining publicity for the telegraph, but no patents, his former fellow-passenger on theSully, Dr. Charles Jackson, had laid claim to a share in the invention. He insisted that the idea had been his and that he had given it to Morse on the trip across the Atlantic. This Morse indignantly denied.
Congress would now take no action upon the invention. A heated political campaign was in progress, and no interest could be aroused in an invention, no matter what were its possibilities in the advancement of the work and development of the nation. Smith was in politics, the Vails were suffering from a financial depression, Professor Gale was a man of very limited means, and so Morse found himself without funds or support. In Paris he had met M. Daguerre, who had just discovered photography. Morse had learned the process and, in connection with Doctor Draper, he fitted up a studio on the roof of the university. Here they took the first daguerreotypes made in America.
Morse's work in art had been so much interrupted that he had but few pupils. The fees that these brought to him were small and irregular, and he was brought to the very verge of starvation. We are told of the call Morse made upon one pupil whose tuition was overdue because of a delay in the arrival of funds from his home.
"Well, my boy," said the professor, "how are we off for money?"
The student explained the situation, adding that he hoped to have the money the following week.
"Next week!" exclaimed Morse. "I shall be dead by next week—dead of starvation."
"Would ten dollars be of any service?" asked the student, astonished and distressed.
"Ten dollars would save my life," was Morse's reply.
The student paid the money—all he had—and they dined together, Morse remarking that it was his first meal for twenty-four hours.
Morse's situation and feelings at this time are also illustrated by a letter he wrote to Smith late in 1841.
I find myself [he wrote] without sympathy or help from any who are associated with me, whose interests, one would think, would impell them to at least inquire if they could render me some assistance. For nearly two years past I have devoted all my time and scanty means, living on a mere pittance, denying myself all pleasures and even necessary food, that I might have a sum, to put my telegraph into such a position before Congress as to insure success to the common enterprise. I am crushed for want of means, and means of so trifling a character, too, that they who know how to ask (which I do not) could obtain in a few hours…. As it is, although everything is favorable, although I have no competition and no opposition—on the contrary, although every member of Congress, so far as I can learn, is favorable—yet I fear all will fail because I am too poor to risk the trifling expense which my journey and residence in Washington will occasion me. I will not run in debt, if I lose the whole matter. No one can tell the days and months of anxiety and labor I have had in perfecting my telegraphic apparatus. For want of means I have been compelled to make with my own hands (and to labor for weeks) a piece of mechanism which could be made much better, and in a tenth the time, by a good mechanician, thus wasting time—time which I cannot recall and which seems double-winged to me.
"Hope deferred maketh the heart sick." It is true, and I have known the full meaning of it. Nothing but the consciousness that I have an invention which is to mark an era in human civilization, and which is to contribute to the happiness of millions, would have sustained me through so many and such lengthened trials of patience in perfecting it.
A patent on the telegraph had been issued to Morse in 1840. The issuance had been delayed at Morse's request, as he desired to first secure foreign patents, his own American rights being protected by the caveat he had filed. Although the commercial possibilities, and hence the money value of the telegraph had not been established, Morse was already troubled with the rival claims of those who sought to secure a share in his invention.
While working and waiting and saving, Morse conceived the idea of laying telegraph wires beneath the water. He prepared a wire by wrapping it in hemp soaked in tar, and then covering the whole with rubber. Choosing a moonlight night in the fall of 1842, he submerged his cable in New York Harbor between Castle Garden and Governors Island. A few signals were transmitted and then the wire was carried away by a dragging anchor. Truly, misfortune seemed to dog Morse's footsteps. This seems to have been the first submarine cable, and in writing of it not long after Morse hazarded the then astonishing prediction that Europe and America would be linked by telegraphic cable.
Failing to secure effective aid from his associates, Morse hung on grimly, fighting alone, and putting all of his strength and energy into the task of establishing an experimental line. It was during these years that he demonstrated his greatness to the full. His letters to the members of the Congressional Committee on Commerce show marked ability. They outline the practical possibilities very clearly. Morse realized not only the financial possibilities of his invention, but its benefit to humanity as well. He also presented very practical estimates of the cost of establishing the line under consideration. The committee again recommended that $30,000 be appropriated for the construction of a Washington-Baltimore line. The politicians had come to look upon Morse as a crank, and it was extremely difficult for his adherents to secure favorable action in the House. Many a Congressman compared Morse and his experiments to mesmerism and similar "isms," and insisted that if the Government gave funds for this experiment it would be called upon to supply funds for senseless trials of weird schemes. The bill finally passed the House by the narrow margin of six votes, the vote being taken orally because so many Congressmen feared to go on record as favoring an appropriation for such a purpose.
The bill had still to pass the Senate, and here there seemed little hope. Morse, who had come to Washington to press his plan, anxiously waited in the galleries. The bill came up for consideration late one evening just before the adjournment. A Senator who noticed Morse went up to him and said:
"There is no use in your staying here. The Senate is not in sympathy with your project. I advise you to give it up, return home, and think no more about it."
The inventor went back to his room, with how heavy a heart we may well imagine. He paid his board bill, and found himself with but thirty-seven cents in the world. After many moments of earnest prayer he retired.
Early next morning there came to him Miss Annie Ellsworth, daughter of his friend the Commissioner of Patents, and said, "Professor, I have come to congratulate you."
"Congratulate me!" replied Morse. "On what?"
"Why," she exclaimed, "on the passage of your bill by the Senate!"
The bill had been passed without debate in the closing moments of the session. As Morse afterward stated, this was the turning-point in the history of the telegraph. His resources were reduced to the minimum, and there was little likelihood that he would have again been able to bring the matter to the attention of Congress.
So pleased was Morse over the news of the appropriation, and so grateful to Miss Ellsworth for her interest in bringing him the good news, that he promised her that she should send the first message when the line was complete. With the Government appropriation at his disposal, Morse immediately set to work upon the Washington-Baltimore line. Professors Gale and Fisher served as his assistants, and Mr. Vail was in direct charge of the construction work. Another person active in the enterprise was Ezra Cornell, who was later to found Cornell University. Cornell had invented a machine for laying wires underground in a pipe.
It was originally planned to place the wires underground, as this was thought necessary or their protection. After running the line some five miles out from Baltimore it was found that this method of installing the line was to be a failure. The insulation was not adequate, and the line could not be operated to the first relay station. A large portion of the $30,000 voted by Congress had been spent and the line was still far from completion. Disaster seemed imminent. Smith lost all faith in the enterprise, demanded most of the remaining money under a contract he had taken to lay the line, and a quarrel broke out between him and Morse which further jeopardized the undertaking.
Morse and such of his lieutenants as remained faithful in this hour of trial, after a long consultation, decided to string the wire on poles. The method of attaching the wire to the poles was yet to be determined. They finally decided to simply bore a hole through each pole near the top and push the wire through it. Stringing the wire in such fashion was no small task, but it was finally accomplished. It was later found necessary to insulate the wire with bottle necks where it passed through the poles. On May 23, 1844, the line was complete. Remembering his promise to Miss Ellsworth, Morse called upon her next morning to give him the first message. She chose, "What hath God wrought?" and early on the morning of the 24th Morse sat at the transmitter in the Supreme Court room in the Capitol and telegraphed these immortal words to Vail at Baltimore. The message was received without difficulty and repeated back to Morse at Washington. The magnetic telegraph was a reality.
Still the general public remained unconvinced. As in the case of Wheatstone's needle telegraph a dramatic incident was needed to demonstrate the utility of this new servant. Fortunately for Morse, the telegraph's opportunity came quickly. The Democratic national convention was in session at Baltimore. After an exciting struggle they dropped Van Buren, then President, and nominated James K. Polk. Silas Wright was named for the Vice-Presidency. At that time Mr. Wright was in Washington. Hearing of the nomination, Alfred Vail telegraphed it to Morse in Washington. Morse communicated with Wright, who stated that he could not accept the honor. The telegraph was ready to carry his message declining the nomination, and within a very few minutes Vail had presented it to the convention at Baltimore, to the intense surprise of the delegates there assembled. They refused to believe that Wright had been communicated with, and sent a committee to Washington to see Wright and make inquiries. They found that the message was genuine, and the utility of the telegraph had been strikingly established.

For some time the telegraph line between Washington and Baltimore remained on exhibition as a curiosity, no charge being made for demonstrating it. Congress made an appropriation to keep the line in operation, Vail acting as operator at the Washington end. On April 1, 1845, the line was put in operation on a commercial basis, service being offered to the public at the rate of one cent for four characters. It was operated as a branch of the Post-office Department. On the 4th of April a visitor from Virginia came into the Washington office wishing to see a demonstration. Up to this time not a paid message had been sent. The visitor, having no permit from the Postmaster-General, was told that he could only see the telegraph in operation by sending a message. One cent being all the money he had other than twenty-dollar bills, he asked for one cent's worth. The Washington operator asked of Baltimore, "What time is it?" which in the code required but one character. The reply came, "One o'clock," another single character. Thus but two characters had been used, or one-half cent's worth of telegraphy. The visitor expressed himself as satisfied, and waived the "change." This penny was the line's first earnings.
Under the terms of the agreement by which Congress had made the appropriation for the experimental line, Morse was bound to give the Government the first right to purchase his invention. He accordingly offered it to the United States for the sum of $100,000. There followed a distressing example of official stupidity and lack of foresight. With the opportunity to own and control the nation's telegraph lines before it the Government declined the offer. This action was taken at the recommendation of the Hon. Cave Johnson, then Postmaster-General, under whose direction the line had been operated. He had been a member of Congress at the time the original appropriation was voted, and had ridiculed the project. The nation was now so unfortunate as to have him as its Postmaster-General, and he reported "that the operation of the telegraph between Washington and Baltimore had not satisfied him that, under any rate of postage that could be adopted, its revenues could be made equal to its expenditures." And yet the telegraph, here offered to the Government for $100,000, was developed under private management until it paid a profit on a capitalization of $100,000,000.
Morse seems to have had a really patriotic motive, as well as a desire for immediate return and the freedom from further worries, in his offer to the Government. He was greatly disappointed at its refusal to purchase, a refusal that was destined to make Morse a wealthy man. Amos Kendall, who had been Postmaster-General under Jackson, was now acting as Morse's agent, and they decided to depend upon private capital. Plans were made for a line between New York and Philadelphia, and to arouse interest and secure capital the apparatus was exhibited in New York City at a charge of twenty-five cents a head. The public refused to patronize in sufficient numbers to even pay expenses, and the entire exhibition was so shabby, and the exhibitors so poverty-stricken, that the sleek capitalists who came departed without investing. Some of the exhibitors slept on chairs or on the floor in the bare room, and it is related that the man who was later to give his name and a share of his fortune to Cornell University was overjoyed at finding a quarter on the sidewalk, as it enabled him to buy a hearty breakfast. Though men of larger means refused to take shares, some in humbler circumstances could recognize the great idea and the wonderful vision which Morse had struggled so long to establish—a vision of a nation linked together by telegraphy. The Magnetic Telegraph Company was formed and work started on the line.
In August of 1845 Morse sailed for Europe in an endeavor to enlist foreign capital. The investors of Europe proved no keener than those of America, and the inventor returned without funds, but imbued with increased patriotism. He had become convinced that the telegraph could and would succeed on American capital alone. In the next year a line was constructed from Philadelphia to Washington, thus extending the New York-Philadelphia line to the capital. Henry O'Reilly, of Rochester, New York, took an active part in this construction work and now took the contract to construct a line from Philadelphia to St. Louis. This line was finished by December of 1847.
The path having been blazed, others sought to establish lines of their own without regard to Morse's patents. One of these was O Reilly, who, on the completion of the line to St. Louis, began one to Now Orleans, without authority from Morse or his company. O'Reilly called his telegraph "The People's Line," and when called to account in the courts insisted not only that his instruments were different from Morse's, and so no infringement of his patents, but also that the Morse system was a harmful monopoly and that "The People's Line" should be encouraged. It was further urged that Wheatstone in England and Steinheil in Germany had invented telegraphs before Morse, and that Professor Henry had invented the relay which made it possible to operate the telegraph over long distances. The suits resulted in a legal victory for Morse, and his patents were maintained.
But still other rival companies built lines, using various forms of apparatus, and though the courts repeatedly upheld Morse's patent rights, the pirating was not effectively checked. The telegraph had come to be a necessity and the original company lacked the capital to construct lines with sufficient rapidity to meet the need. Within ten years after the first line had been put into operation the more thickly settled portions of the United States were served by scores of telegraph lines owned by a dozen different companies. Hardly any of these were making any money, though the service was poor and the rates were high. They were all operating on too small a scale and business uses of the telegraph had not yet developed sufficiently.
An amalgamation of the scattered, competing lines was needed, both to secure better service for the public and proper dividends for the investors. This amalgamation was effected by Mr. Hiram Sibley, who organized the Western Union in 1856. The plan was ridiculed at the time, some one stating that "The Western Union seems very like collecting all the paupers in the State and arranging them into a union so as to make rich men of them." But these pauper companies did become rich once they were united under efficient management.
The nation was just then stretching herself across to the Pacific. The commercial importance of California was growing rapidly. By 1857 stage-coaches were crossing the plains and the pony-express riders were carrying the mail. The pioneers of the telegraph felt that a line should span the continent. This was then a tremendous undertaking, and when Mr. Sibley proposed that the Western Union should undertake the construction of such a line he was met with the strongest opposition. The explorations of Frémont were not far in the past, and the vast extent of country west of the Mississippi was regarded as a wilderness peopled with savages and almost impossible of development. But Sibley had faith; he was possessed of Morse's vision and Morse's courage. The Western Union refusing to undertake the enterprise, he began it himself. The Government, realizing the military and administrative value of a telegraph line to California, subsidized the work. Additional funds were raised and a route selected was through Omaha and Salt Lake City to San Francisco.
The undertaking proved less formidable than had been anticipated, for, instead of two years, less than five months were occupied in completing the line. Sibley's tact and ability did much to avoid opposition by the Indians. He made the red men his friends and impressed upon them the wonder of the telegraph. When the line was in operation between Fort Kearney and Fort Laramie he invited the chief of the Arapahoes at Fort Kearney to communicate by telegraph with his friend the chief of the Sioux at Fort Laramie. The two chiefs exchanged telegrams and were deeply impressed. They were told that the telegraph was the voice of the Manitou or Great Spirit. To convince them it was suggested that they meet half-way and compare their experiences. Though they were five hundred miles apart, they started out on horseback, and on meeting each other found that the line had carried their words truly. The story spread among the tribes, and so the telegraph line became almost sacred to the Indians. They might raid the stations and kill the operators, but they seldom molested the wires.
Among many ignorant peoples the establishment of the telegraph has been attained with no small difficulty. The Chinese showed a dread of the telegraph, frequently breaking down the early lines because they believed that they would take away the good luck of their district. The Arabs, on the other hand, did not oppose the telegraph. This is partly because the name is one which they can understand,telmeaning wire to them, andaraph, to know. Thus in Arabictele-agraphmeans to know by wire.
Just as the Indians of our own plains had difficulty in understanding the telegraph, so the primitive peoples in other parts of the world could scarce believe it possible. A story is told of the construction of an early line in British India. The natives inquired the purpose of the wire from the head man.
"The wire is to carry messages to Calcutta," he replied.
"But how can words run along a wire?" they asked.
The head man puzzled for a moment.
"If there were a dog," he replied, "with a tail long enough to reach from here to Calcutta, and you pinched his tail here, wouldn't he howl in Calcutta?"
Once Sibley and the other American telegraph pioneers had spanned the continent, they began plans for spanning the globe. Their idea was to unite America and Europe by a line stretched through British Columbia, Alaska, the Aleutian Islands, and Siberia. Siberia had been connected with European Russia, and thus practically the entire line could be stretched on land, only short submarine cables being necessary. It was then seriously doubted that cables long enough to cross the Atlantic were practicable. The expedition started in 1865, a fleet of thirty vessels carrying the men and supplies. Tremendous difficulties had been overcome and a considerable part of the work accomplished when the successful completion of the Atlantic cable made the work useless. Nearly three million dollars had been expended by the Western Union in this attempt. Yet, despite this loss, its affairs were so generally successful and the need for the telegraph so real that it continued to thrive until it reached its present remarkable development.
While the line-builders were busy stretching telegraph wires into almost every city and town in the nation, others were perfecting the apparatus. Alfred Vail was a leading figure in this work. Already he had played a large part in designing and constructing the apparatus to carry out Morse's ideas, and he continued to improve and perfect until practically nothing remained of Morse's original apparatus. The original Morse transmitter had consisted of a porte-rule and movable type. This was cumbersome, and Vail substituted a simple key to make and break the circuit. Vail had also constructed the apparatus to emboss the message upon the moving strip of paper, but this he now improved upon. The receiving apparatus was simplified and the pen was replaced by a disk smeared with ink which marked the dots and dashes upon the paper.
As we have noticed, Morse took particular pride in the fact that the receiving apparatus in his telegraph was self-recording, and considered this as one of the most important parts of his system. But when the telegraph began to come into commercial use the operators at the receiving end noticed that they could read the messages from the long and short periods between the clicks of the receiving mechanism. Thus they were taking the message by ear and the recording mechanism was superfluous. Rules and fines failed to break them of the habit, and Vail, recognizing the utility of the development, constructed a receiver which had no recording device, but from which the messages were read by listening to the clicks as the armature struck against the frame in which it was set. Thus the telegraph returned in its elements to the form of Professor Henry's original bell telegraph.
With his bell telegraph and his relay Henry had the elements of a successful system. He failed, however, to develop them practically or to introduce them to the attention of the public. He was the man of science rather than the practical inventor. Alfred Vail, joining with Morse after the latter had conceived the telegraph, but before his apparatus was in practical form, was a tireless and invaluable mechanical assistant. His inventions of apparatus were of the utmost practical value, and he played a very large part in bringing the telegraph to a form where it could serve man effectively. After success had been won Morse did not extend to Vail the credit which it seems was his due.
Yet, though Morse made free use of the ideas and assistance of others, he was richly deserving of a major portion of the fame and the rewards that came to him as inventor of the telegraph. Morse was the directing genius; he contributed the idea and the leadership, and bore the brunt of the burdens when all was most discouraging.
Honors were heaped upon Morse both at home and abroad as his telegraph established itself in all parts of the world. Orders of knighthood, medals, and decorations were conferred upon him. Though he had failed to secure foreign patents, many of the foreign governments recognized the value of his invention, and France, Austria, Belgium, Netherlands, Russia, Sweden, Turkey, and some smaller nations joined in paying him a testimonial of four hundred thousand francs. It is to be noticed that Great Britain did not join in this testimonial, though Morse's system had been adopted there in preference to the one developed by Wheatstone.
In 1871 a statue of Morse was erected in Central Park, New York City. It was in the spring of the next year that another statue was unveiled, this time one of Benjamin Franklin, and Morse presided at the ceremonies. The venerable man received a tremendous ovation on this occasion, but the cold of the day proved too great a strain upon him. He contracted a cold which eventually resulted in his death on April 2, 1872.
While extended consideration cannot be given here to the telegraphic inventions of Thomas A. Edison, no discussion of the telegraph should close without at least some mention of his work in this field. Edison started his career as a telegrapher, and his first inventions were improvements in the telegraph. His more recent and more wonderful inventions have thrown his telegraphic inventions into the shadow. On the telegraph as invented by Morse but one message could be sent over a single wire at one time. It was later discovered that two messages' could be sent over the single wire in opposite directions at the same time. This was called duplex telegraphy. Edison invented duplex telegraphy by which two messages could be sent over the same wire in the same direction at the same time. Later he succeeded in combining the two, which resulted in the quadruplex, by which four messages may be sent over one wire at one time. Though Edison received comparatively little for this invention, its commercial value may be estimated from the statement by the president of the Western Union that it saved that company half a million dollars in a single year. Edison's quadruplex system was also adopted by the British lines.
Before this he had perfected an automatic telegraph, work on which had been begun by George Little, an Englishman. Little could make the apparatus effective only over a short line and attained no very great speed. Edison improved the apparatus until it transmitted thirty-five hundred words a minute between New York and Philadelphia. Such is the perfection to which Morse's marvel has been brought in the hands of the most able of modern inventors.

The idea of laying telegraph wires beneath the sea was discussed long before a practical telegraph for use on land had been attained. It is recorded that a Spaniard suggested submarine telegraphy in 1795. Experiments were conducted early in the nineteenth century with various materials in an effort to find a covering for the wires which would be both a non-conductor of electricity and impervious to water. An employee of the East India Company made an effort to lay a cable across the river Hugli as early as 1838. His method was to coat the wire with pitch inclose it in split rattan, and then wrap the whole with tarred yarn. Wheatstone discussed a Calais-Dover cable in 1840, but it remained for Morse to actually lay an experimental cable. We have already heard of his experiments in New York Harbor in 1842. His insulation was tarred hemp and India rubber. Wheatstone performed a similar experiment in the Bay of Swansea a few months later.
Perhaps the first practical submarine cable was laid by Ezra Cornell, one of Morse's associates, in 1845. He laid twelve miles of cable in the Hudson River, connecting Fort Lee with New York City. The cable consisted of two cotton-covered wires inclosed in rubber, and the whole incased in a lead pipe. This cable was in use for several months until it was carried away by the ice in the winter of 1846.
These early experimenters found the greatest difficulty in incasing their wires in rubber, practical methods of working that substance being then unknown. The discovery of gutta-percha by a Scotch surveyor of the East India Company in 1842, and the invention of a machine for applying it to a wire, by Dr. Werner Siemens, proved a great aid to the cable-makers. These gutta-percha-covered wires were used for underground telegraphy both in England and on the Continent. Tests were made with such a cable for submarine work off Dover in 1849, and, proving successful, the first cable across the English Channel was laid the next year by John Watkins Brett. The cable was weighted with pieces of lead fastened on every hundred yards. A few incoherent signals were exchanged and the communication ceased. A Boulogne fisherman had caught the new cable in his trawl, and, raising it, had cut a section away. This he had borne to port as a great treasure, believing the copper to be gold in some new form of deposit. This experience taught the need of greater protection for a cable, and the next year another was laid across the Channel, which was protected by hemp and wire wrappings. This proved successful. In 1852 England and Ireland were joined by cable, and the next year a cable was laid across the North Sea to Holland. The success of these short cables might have promised success in an attempt to cross the Atlantic had not failures in the deep water of the Mediterranean made it seem an impossibility.
We have noted that Morse suggested the possibility of uniting Europe and America by cable. The same thought had occurred to others, but the undertaking was so vast and the problems so little understood that for many years none were bold enough to undertake the project. A telegraph from New York to St. John's, Newfoundland, was planned, however, which was to lessen the time of communication between the continents. News brought by boats from England could be landed at St. John's and telegraphed to New York, thus saving two days. F.N. Gisborne secured the concession for such a line in 1852, and began the construction. Cables were required to connect Newfoundland with the continent, and to cross the Gulf of St. Lawrence, but the rest of the line was to be strung through the forests.
Before much had been accomplished, Gisborne had run out of funds, and work was suspended. In 1854 Gisborne met Cyrus West Field, of New York, a retired merchant of means. Field became interested in Gisborne's project, and as he examined the globe in his library the thought occurred to him that the line to St. John's was but a start on the way to England. The idea aroused his enthusiasm, and he determined to embark upon the gigantic enterprise. He knew nothing of telegraph cables or of the sea-bottom, and so sought expert information on the subject.
One important question was as to the condition of the sea-bottom on which the cable must rest. Lieutenant Berryman of the United States Navy had taken a series of soundings and stated that the sea-bottom between Newfoundland and Ireland was a comparatively level plateau covered with soft ooze, and at a depth of about two thousand fathoms. This seemed to the investigators to have been provided for the especial purpose of receiving a submarine cable, so admirably was it suited to this purpose. Morse was consulted, and assured Field that the project was entirely feasible, and that a submarine cable once laid between the continents could be operated successfully.
Field thereupon adopted the plans of Gisborne as the first step in the larger undertaking. In 1855 an attempt was made to lay a cable across the Gulf of St. Lawrence, but a storm arose, and the cable had to be cut to save the ship from which it was being laid. Another attempt was made the following summer with better equipment, and the cable was successfully completed. Other parts of the line had been finished, the telegraph now stretched a thousand miles toward England, and New York was connected with St. John's.
Desiring more detailed information of the ocean-bed along the proposed route, Field secured the assistance of the United States and British governments. Lieutenant Berryman, U.S.N., in theArctic, and Lieutenant Dayman, R.N., in theCyclops, made a careful survey. Their soundings revealed a ridge near the Irish coast, but the slope was gradual and the general conditions seemed especially favorable.
The preliminary work had been done by an American company with Field at the head and Morse as electrician. Now Field went to England to secure capital sufficient for the larger enterprise. With the assistance of Mr. J.W. Brett he organized the Atlantic Telegraph Company, Field himself supplying a quarter of the capital. Associated with Field and Brett in the leadership of the enterprise was Charles Tiltson Bright, a young Englishman who became engineer for the new company.
Besides the enormous engineering difficulties of producing a cable long enough and strong enough, and laying it at the bottom of the Atlantic, there were electrical problems involved far greater than Morse seems to have realized. It had been discovered that the passage of a current through a submarine cable is seriously retarded. The retarding of the current as it passes through the water is a difficulty that does not exist with the land telegraph stretched on poles. Faraday had demonstrated that this retarding was caused by induction between the electricity in the wire and the water about the cable. The passage of the current through the wire induces currents in the water, and these moving in the opposite direction act as a drag on the passage of the message through the wire. What the effect of this phenomenon would be on a cable long enough to cross the Atlantic wan a serious problem that required deep study by the company's engineers. It seemed entirely possible that the messages would move so slowly that the operation of the cable, once it was laid, would not pay.
Faraday failed to give any definite information on the subject, but Professor William Thomson worked out the law of retardation accurately and furnished to the cable-builders the accurate information which was required. Doctor Whitehouse, electrician for the Atlantic Company, conducted some experiments of his own and questioned the accuracy of Thomson's statements. Thomson maintained his position so ably, and proved himself so thoroughly a master of the subject that Field and his associates decided to enlist him in the enterprise. This addition to the forces was one of the utmost importance. William Thomson, later to become Lord Kelvin, was probably the ablest scientist of his generation, and was destined to prove his great abilities in his early work with the Atlantic cable.
William Thomson was born in Belfast, Ireland, in 1824. His father was a teacher and took an especially keen interest in the affairs of his boys because their mother had died while William was very young. When William was eight years of age his father removed to Glasgow, Scotland, where he had secured the chair of mathematics in Glasgow University. His early education he secured from his father, and this training, coupled with his natural brilliancy, enabled him to develop genuine precocity. At the age of eight he attended his father's university lectures as a visitor, and it is reported that on one occasion he answered his father's questions when all of the class had failed. At the age of ten he entered the university, together with his brother James, who was but two years older. The brothers displayed marked interest in science and invention, eagerly pursued their studies in these branches, and performed many electrical experiments together.

James took the degrees B.A. and M.A. in successive years. Though William also passed the examinations, he did not take the degrees, because he had decided to go to Cambridge, and it was thought best that he take all his degrees from that great school. In writing to his older brother at this time, William was accustomed to sign himself "B.A.T.A.I.A.P.," which signified "B.A. to all intents and purposes." After finishing their work at Glasgow the boys traveled extensively on the Continent.
At seventeen William entered St. Peter's College, Cambridge University, taking courses in advanced mathematics and continuing to distinguish himself. He took an active part in the life of the university, making something of a record us an athlete, winning the silver sculls, and rowing on a 'varsity crew which took the measure of Oxford in the great annual boat-race. He also interested himself in literature and music, but his real passion was science. Already he had written many learned essays on mathematical electricity and was accomplishing valuable research work. On the completion of his work at Cambridge he secured a fellowship which brought him an income of a thousand dollars a year and enabled him to pursue his studies in Paris.
When he was but twenty-two years of age he was made professor of natural philosophy at the University of Glasgow. Though young, he proved entirely successful, and wan immensely popular with his students. At that time the university had no experimental laboratory, and Professor Thomson and his pupils performed their experiments in the professor's room and in an abandoned coal-cellar, slowly developing a laboratory for themselves. His development continued until, when at the age of thirty-three he was called upon to assist with the work of laying an Atlantic cable, he was possessed of scientific attainments which made him invaluable among the cable pioneers.
Making the Cable—The First Attempt at Laying—Another EffortChecked by Storm—The Cable Laid at Last—Messages Cross theOcean—The Cable Fails—Professor Thomson's Inventions andDiscoveries—Their Part in Designing and Constructing an ImprovedCable and Apparatus.
Field and his business associates were extremely anxious that the cable be laid with all possible speed, and little time was allowed the engineers and electricians for experimentation. The work of building the cable was begun early in 1857 by two English firms. It consisted of seven copper wires covered with gutta-percha and wound with tarred hemp. Over this were wound heavy iron wires to give protection and added strength. The whole weighed about a ton to the mile, and was both strong and flexible. The distance from the west coast of Ireland to Newfoundland being 1,640 nautical miles, it was decided to supply 2,500 miles of cable, an extra length being, of course, necessary to allow for the inequalities at the bottom of the sea, and the possibility of accident.
The British and American governments had already provided subsidies, and they now supplied war-ships for use in the work of laying the cable. TheAgamemnon, one of the largest of England's war-ships, and theNiagara, giant of the United States Navy, were to do the actual work of cable-laying, the cable being divided between them. They were accompanied by the United States frigateSusquehannaand the British war-shipsLeopardandCyclops. In August of 1857 the fleet assembled on the Irish coast for the start, and the American sailors landed the end of the cable amid great ceremony.
The work of cable-laying was begun by theNiagara, which steamed slowly away, accompanied by the fleet. The great cable payed out smoothly as the Irish coast was left behind and the frigate increased her speed. The submarine hill with its dangerous slopes was safely passed, and it was felt that the greatest danger was past. The paying-out machinery seemed to be working perfectly. Telegraphic communication was constantly maintained with the shore end. For six days all went well and nearly four hundred miles of cable had been laid.
With the cable dropping to the bottom two miles down it was found that it was flowing out at the rate of six miles an hour while theNiagarawas steaming but four. It was evident that the cable was being wasted, and to prevent its running out too fast at this great depth the brake controlling the flow of the cable was tightened. The stern of the vessel rising suddenly on a wave, the strain proved too great and the cable parted and was lost. Instant grief swept over the ship and squadron, for the heart of every one was in the great enterprise. It was felt that it would be useless to attempt to grapple the cable at this great depth, and there seemed nothing to do but abandon it and return.
The loss of the cable and of a year's time—since another attempt could not be made until the next season—resulted in a total loss to the company of half a million dollars. Public realization of the magnitude of the task had been awakened by the failure of the first expedition and Field found it far from easy to raise additional capital. It was finally accomplished, however, and a new supply of cable was constructed.
Professor Thomson had been studying the problems of submarine telegraphy with growing enthusiasm, and had now arrived at the conclusion that the conductivity of the cable depended very largely upon the purity of the copper employed. He accordingly saw to it that in the construction of the new section all the wires were carefully tested and such as did not prove perfect were discarded. In the mean time the engineers were busy improving the paying-out machinery. They designed an automatic brake which would release the cable instantly upon the strain becoming too great. It was thus hoped to avoid a recurrence of the former accident. Chief-Engineer Bright also arranged a trial trip for the purpose of drilling the staff in their various duties.
The same vessels were provided to lay the cable on the second attempt and the fleet sailed in June of 1858, this time without celebration or public ceremony. On this occasion the recommendation of Chief-Engineer Bright was followed, and it was arranged that theNiagaraandAgamemnonshould meet in mid-ocean, there splice the cable together and proceed in opposite directions, laying the cable simultaneously. On this expedition Professor Thomson was to assume the real scientific leadership, Professor Morse, though he retained his position with the company, taking no active part.
The ships had not proceeded any great distance before they ran into a terrible gale. TheAgamemnonhad an especially difficult time of it, her great load of cable overbalancing the ship and threatening to break loose again and again and carry the great vessel and her precious cargo to the bottom. The storm continued for over a week, and when at last it had blown itself out theAgamemnonresembled a wreck and many of her crew had been seriously injured. But the cable had been saved and the expedition was enabled to proceed to the rendezvous. TheNiagara, a larger ship, had weathered the storm without mishap.
The splice was effected on Saturday, the 26th, but before three miles had been laid the cable caught in the paying-out machinery on theNiagaraand was broken off. Another splice was made that evening and the ships started again. The two vessels kept in communication with each other by telegraph as they proceeded, and anxious inquiries and many tests marked the progress of the work. When fifty miles were out, the cable parted again at some point between the vessels and they again sought the rendezvous in mid-Atlantic. Sufficient cable still remained and a third start was made. For a few days all went well and some four hundred miles of cable had been laid with success as the messages passing from ship to ship clearly demonstrated. Field, Thomson, and Bright began to believe that their great enterprise was to be crowned with success when the cable broke again, this time about twenty feet astern of theAgamemnon. This time there was no apparent reason for the mishap, the cable having parted without warning when under no unusual strain.
The vessels returned to Queenstown, and Field and Thomson went to London, where the directors of the company were assembled. Many were in favor of abandoning the enterprise, selling the remaining cable for what it would bring, and saving as much of their investment as possible. But Field and Thomson were not of the sort who are easily discouraged, and they managed to rouse fresh courage in their associates. Yet another attempt was decided upon, and with replenished stores theAgamemnonandNiagaraonce again proceeded to the rendezvous.
The fourth start was made on the 29th of July. On several occasions as the work progressed communication failed, and Professor Thomson on theAgamemnonand the other electricians on theNiagaraspent many anxious moments fearing that the line had again been severed. On each occasion, however, the current resumed. It was afterward determined that the difficulties were because of faulty batteries rather than leaks in the cable. On both ships bad spots were found in the cable as it was uncoiled and some quick work was necessary to repair them before they dropped into the sea, since it was practically impossible to stop the flow of the cable without breaking it. TheNiagarahad some narrow escapes from icebergs, and theAgamemnonhad difficulties with ships which passed too close and a whale which swam close to the ship and grazed the precious cable. But this time there was no break and the ships approached their respective destinations with the cable still carrying messages between them. TheNiagarareached the Newfoundland coast on August 4th, and early the next morning landed the cable in the cable-house at Trinity Bay. TheAgamemnonreached the Irish coast but a few hours later, and her end of the cable was landed on the afternoon of the same day.
The public, because of the repeated failures, had come to look upon the cable project as a sort of gigantic wild-goose chase. The news that a cable had at last been laid across the ocean was received with incredulity. Becoming convinced at last, there was great rejoicing in England and America. Queen Victoria sent to President Buchanan a congratulatory message in which she expressed the hope "that the electric cable which now connects Great Britain with the United States will prove an additional link between the two nations, whose friendship is founded upon their mutual interest and reciprocal esteem." The President responded in similar vein, and expressed the hope that the neutrality of the cable might be established.
Honors were showered upon the leaders in the enterprise. Charles Bright, the chief engineer, was knighted, though he was then but twenty-six years of age. Banquet after banquet was held in England at which Bright and Thomson were the guests of honor. New York celebrated in similar fashion. A grand salute of one hundred guns was fired, the streets were decorated, and the city was illuminated at night. The festivities rose to the highest pitch in September with Field receiving the plaudits of all New York. Special services were held in Trinity Church, and a great celebration was held in Crystal Palace. The mayor presented to Field a golden casket, and the ceremony was followed by a torchlight parade. That very day the last message went over the wire.
The shock to the public was tremendous. Many insisted that the cable had never been operated and that the entire affair was a hoax. This was quickly disproved. Aside from the messages between Queen and President many news messages had gone over the cable and it had proved of great value to the British Government. The Indian mutiny had been in progress and regiments in Canada had received orders by mail to sail for India. News reached England that the mutiny was at an end, and the cable enabled the Government to countermand the orders, thus saving a quarter of a million dollars that would have been expended in transporting the troops.
The engineers to whom the operations of the cable had been intrusted had decided that very high voltages were necessary to its successful operation. They had accordingly installed huge induction coils and sent currents of two thousand volts over the line. Even this voltage had failed to operate the Morse instruments, the drag by induction proving too great. The strain of this high voltage had a very serious effect upon the insulation. Abandoning the Morse instruments and the high voltage, recourse was then had to Professor Thomson's instruments, which proved entirely effective with ordinary battery current.
Because of the effect of induction the current is much delayed in traveling through a long submarine cable and arrives in waves. Professor Thomson devised his mirror galvanometer to meet this difficulty. This device consists of a large coil of very fine wire, in the center of which, in a small air-chamber, is a tiny mirror. Mounted on the back of the mirror are very small magnets. The mirror is suspended by a fiber of the finest silk. Thus the weakest of currents coming in over the wire serve to deflect the mirror, and a beam of light being directed upon the mirror and reflected by it upon a screen, the slightest movement of the mirror is made visible. If the mirror swings too far its action is deadened by compressing the air in the chamber. The instrument is one of the greatest delicacy. Such was the greatest contribution of Professor Thomson to submarine telegraphy. Without it the cable could not have been operated even for a short period. Had it been used from the first the line would not have been ruined and might have been used for a considerable period.
Professor Thomson together with Engineer Bright made a careful investigation of the causes of failure. The professor pointed out that had the mirror galvanometer been used with a moderate current the cable could have been continued in successful operation. Ha continued to improve this apparatus and at the same time busied himself with a recording instrument to be used for cable work. Both Thomson and Bright had recommended a larger and stronger cable, and other failures in cable-laying in the Red Sea and elsewhere in the next few years bore out their contentions. But with each failure new experience was gained and methods were perfected. Professor Thomson continued his work with the utmost diligence and continued to add to the fund of scientific knowledge on the subject. So it was that he was prepared to take his place as scientific leader of the next great effort.

The early 'sixties were trying years for the cable pioneers. It required all of Field's splendid genius and energy to keep the project alive. In the face of repeated failures, and doubt as to whether messages could be sent rapidly enough to make any cable a commercial success, it was extremely difficult to raise fresh capital. America continued to evince interest in the cable, but with, the Civil War in progress it was not easy to raise funds. But no discouragement could deter Field. Though he suffered severely from seasickness, he crossed the Atlantic sixty-four times in behalf of the great enterprise which he had begun.
It was necessary to raise three million dollars to provide a cable of the improved type decided upon and to install it properly. The English firm of Glass, Eliot & Company, which was to manufacture the cable, took a very large part of the stock. The new cable was designed in accordance with the principles enunciated by Professor Thomson. The conductor consisted of seven wires of pure copper, weighing three hundred pounds to the mile. This copper core was covered with Chatterton's compound, which served as water-proofing. This was surrounded by four layers of gutta-percha, cemented together by the compound, and about this hemp was wound. The outer layer consisted of eighteen steel wires wound spirally, each being covered with a wrapping of hemp impregnated with a preservative solution. The new cable was twice as heavy as the old and more than twice as strong, a great advance having been made in the methods of manufacturing steel wire.
It was decided that the cable should, be laid by one vessel, instead of endeavoring to work from two as in the past. Happily, a boat was available which was fitted to carry this enormous burden. This was theGreat Eastern, a mammoth vessel far in advance of her time. This great ship of 22,500 tons had been completed in 1857, but had not proved a commercial success. The docks of that day were not adequate, the harbors were not deep enough, and the cargoes were insufficient. She had long lain idle when she was secured by the cable company and fitted out for the purpose of laying the cable, which was the first useful work which had been found for the great ship. The 2,300 miles of heavy cable was coiled into the hull and paying-out machinery was installed upon the decks. Huge quantities of coal and other supplies were added.
Capt. James Anderson of the Cunard Line was placed in command of the ship for the expedition, with Captain Moriarty, R.N., as navigating officer. Professor Thomson and Mr. C.F. Varley represented the Atlantic Telegraph Company as electricians and scientific advisers. Mr. Samuel Canning was engineer in charge for the contractors. Mr. Field was also on board.
It was on July 23, 1865, that the expedition started from the Irish coast, where the eastern end of the cable had been landed. Less than a hundred miles of cable had been laid when the electricians discovered a fault in the cable. TheGreat Easternwas stopped, the course was retraced, and the cable picked up until the fault was reached. It was found that a piece of iron wire had in some way pierced the cable so that the insulation was ruined. This was repaired and the work of laying was again commenced. Five days later, when some seven hundred miles of cable had been laid, communication was again interrupted, and once again they turned back, laboriously lifting the heavy cable from the depths, searching for the break. Again a wire was found thrust through the cable, and this occasioned no little worry, as it was feared that this was being done maliciously.
It was on August 2d that the next fault was discovered. Nearly two-thirds of the cable was now in place and the depth was here over one mile. Raising the cable was particularly difficult, and just at this juncture theGreat Eastern'smachinery broke down, leaving her without power and at the mercy of the waves. Subjected to an enormous strain, the precious cable parted and was lost. Despite the great depth, efforts were made to grapple the lost cable. Twice the cable was hooked, but on both occasions the rope parted and after days of tedious work the supply of rope was exhausted and it was necessary to return to England. Still another cable expedition had ended in failure.
Field, the indomitable, began all over again, raising additional funds for a new start. TheGreat Easternhad proved entirely satisfactory, and it was hoped that with improvements in the grappling-gear the cable might be recovered. The old company gave way before a new organization known as the Anglo-American Telegraph Company. It was decided to lay an entirely new cable, and then to endeavor to complete the one partially laid in 1865.
With no services other than private prayers at the station on the Irish shore, theGreat Easternsteamed away for the new effort on July 13, 1866. This time the principal difficulties arose within the ship. Twice the cable became tangled in the tanks and it was necessary to stop the ship while the mass was straightened out. Most of the time the "coffee-mill," as the seamen called the paying-out machinery, ground steadily away and the cable sank into the sea. As the work progressed Field and Thomson, who had suffered so many failures in their great enterprise, watched with increasing anxiety. They were almost afraid to hope that the good fortune would continue.
Just two weeks after the Irish coast had been left behind theGreat Easternapproached Newfoundland just as the shadows of night were added to those of a thick fog. On the next morning, July 28th, she steamed into Trinity Bay, where flags were flying in the little town in honor of the great accomplishment. Amid salutes and cheers the cable was landed and communication between the continents was established. Almost the first news that came over the wire was that of the signing of the treaty of peace which ended the war between Prussia and Austria.
Early in August theGreat Easternagain steamed away to search for the cable broken the year before. Arriving on the spot, the grapples were thrown out and the tedious work of dragging the sea-bottom was begun. After many efforts the cable was finally secured and raised to the surface. A new section was spliced on and the ship again turned toward America. On September 7th the second cable was successfully landed, and two wires were now in operation between the continents. Thus was the great task doubly fulfilled. Once again there were public celebrations in England and America. Field received the deserved plaudits of his countrymen and Thomson was knighted in recognition of his achievements.
[Illustration: THE "GREAT EASTERN" LAYING THE ATLANTIC CABLE. 1866]
The new cables proved a success and were kept in operation for many years. Thomson's mirror receiver had been improved until it displayed remarkable sensitiveness. Using the current from a battery placed in a lady's thimble, a message was sent across the Atlantic through one cable and back through the other. Professor Thomson was to give to submarine telegraphy an even more remarkable instrument. The mirror instrument did not give a permanent record of the messages. The problem of devising a means of recording the messages delicate enough so that it could be operated with rapidity by the faint currents coming over a long cable was extremely difficult. But Thomson solved it with his siphon recorder. In this a small coil is suspended between the poles of a large magnet; the coil being free to turn upon its axis. When the current from the cable passes through the coil it moves, and so varies the position of the ink-siphon which is attached to it. The friction of a pen on paper would have proved too great a drag on so delicate an instrument, and so a tiny jet of ink from the siphon was substituted. The ink is made to pass through the siphon with sufficient force to mark down the message by a delightfully ingenious method. Thomson simply arranged to electrify the ink, and it rushes through the tiny opening on to the paper just as lightning leaps from cloud to earth.
Professor, now Sir, Thomson continued to take an active part in the work of designing and laying new cables. Not only did he contribute the apparatus and the scientific information which made cables possible, but he attained renown as a physicist and a scientist in many other fields. In 1892 he was given the title of Lord Kelvin, and it was by this name that he was known as the leading physicist of his day. He survived until 1907.
To Cyrus W. Field must be assigned a very large share of the credit for the establishment of telegraphic communication between the continents. He gave his fortune and all of his tremendous energy and ability to the enterprise and kept it alive through failure after failure. He was a promoter of the highest type, the business man who recognized a great human need and a great opportunity for service. Without his efforts the scientific discoveries of Thomson could scarcely have been put to practical use.
The success of the first cable inspired others. In 1869 a cable from France to the United States was laid from theGreat Eastern. In 1875 the Direct United States Cable Company laid another cable to England, which was followed by another cable to France. One cable after another was laid until there are now a score. This second great development in communication served to bring the two continents much closer together in business and in thought and has proved of untold benefit.
