The plan of operations this time was for the vessels to proceed to a given point in mid-ocean, and there unite the two ends of the cable, after which the "Niagara" should proceed toward Newfoundland and the "Agamemnon" toward Ireland, and it was supposed that each vessel would make land about the same time. This was believed to be a better plan than the one pursued in the first expedition.

The squadron sailed from Plymouth on the 10th of June. The weather was favorable for the first two or three clays of the voyage, but on the 13th a severe gale set in, which lasted for over a week, and came near causing the "Agamemnon" to founder beneath her immense load, a portion of which broke loose in her hold. All the vessels succeeded in weathering the storm, however, and on the 25th reached the rendezvous in mid-ocean. The next day the splice was made, and the ships set out for their respective destinations. Before they had gone three miles the machinery of the "Niagara" caught the cable and broke it. A second splice was made, but when each ship had paid out about forty miles, the electric current suddenly ceased. The cable was cut promptly, and the two vessels at once returned to the rendezvous, where they rejoined each other on the 28th. A comparison of the logs of the two ships "showed the painful and mysterious fact that at the same second of time each vessel discovered that a total fracture had taken place, at a distance of certainly not less than ten miles from each ship, in fact, as well as can be judged, at the bottom of the ocean." A third splice was made without delay, and the two ships again set out for the opposite shores of the Atlantic. This time about two hundred miles of the cable were successfully laid, when it parted about twenty feet from the stern of the "Agamemnon." The "Niagara," being unable to communicate with the English frigate, bore away for Queenstown, where she was joined a few days later by the "Agamemnon."

This second failure greatly disheartened the directors, and it required all Mr. Field's persuasiveness to induce them to sanction another attempt. Yet he prevailed, and, hastening from London to Queenstown, sailed with the telegraph fleet on the third attempt to lay the cable, leaving Queenstown on the 17th of July. The rendezvous was reached on the 28th, and on the 29th the splice was made; and the "Niagara" and "Agamemnon" parted company. This time the undertaking was successful. The cable was laid across the Atlantic, the "Niagara" reaching Trinity Bay, Newfoundland, on the 5th of August, and the "Agamemnon" arriving at Valentia, Ireland, a few hours later on the same day. Signals were sent across the entire length of the line, from shore to shore, with ease and rapidity, and nothing occurred to mar the success of the mighty undertaking.

The successful laying of the cable was hailed with the liveliest joy on both sides of the Atlantic, and those who had participated in it were regarded as heroes. But great as was the achievement, it was not destined to be a lasting success. After working for four weeks, the electric current suddenly ceased on the 1st of September. It never worked perfectly at any period of its existence, but it did transmit a number of messages with intelligibleness, and thus put an end to all doubt in the minds of the scientific men of the expedition of the feasibility of laying a successful line across the ocean.

The public generally and the directors of the company were greatly disappointed, and many of-the latter and nearly all of the former declared that all such attempts must of necessity fail. Some persons even went so far as to avow their belief that the statements as to the successful transmission of signals over the wire were false; but the proofs that the wire did work properly for awhile are too strong to allow us to accord the slightest weight to this disbelief. But whether signals had passed over the wire or not, there could be no doubt that the cable had ceased to respond to the efforts of the electricians, and was a total failure, and the discouragement of nearly every one connected with it was most profound.

Mr. Field and one or two others were the only persons who retained the slightest confidence in the enterprise, and it was clear to them that any further effort to secure the aid of private capital would be useless just then. An appeal was made to the British Government. It was urged that the work was too great to be undertaken by private capital alone, and that, since it was to be more of a public than a private nature, it was but just that the Government should undertake it. The company asked the Government to guarantee the interest on a certain amount of stock, even if the second attempt should not prove a complete success. The failure of the Red Sea cable, to which the British Government had given an unconditional guarantee, had just occurred, and had caused a considerable loss to the treasury, and the Government was not willing to assume another such risk. Anxious, however, for the success of the Atlantic telegraph, it increased its subsidy from fourteen thousand to twenty thousand pounds, and agreed to guarantee eight per cent, on six hundred thousand pounds of new capital for twenty-five years, upon the single condition that the cable should be made to work successfully.

This was not all, however. The Government caused further soundings to be made off the coast of Ireland, which effectually dispelled all the fears which had been entertained of a submarine mountain which would prove an impassable barrier in the path of an ocean telegraph. In addition to this, it caused the organization of a board of distinguished scientific men for the purpose of determining all the difficult problems of submarine telegraphy. This board met in 1859, and sat two years. The result of its experiments and investigations was a declaration, signed by the members, that a cable properly made, "and paid into the ocean with the most improved machinery, possesses every prospect of not only being successfully laid in the first instance, but may reasonably be relied upon to continue many years in an efficient-state for the transmission of signals."

Meanwhile, Mr. Field labored energetically to revive the company. The war which had broken out in the United States brought home to our Government the urgent need of telegraphic communication with Europe, and Mr. Field had no difficulty in obtaining from the President an assurance that this Government would be most happy to join with Great Britain in promoting this great international work. He addressed meetings of merchants in various American cities, and displayed the greatest energy in his efforts to enlist the aid of American capital. Very little was accomplished, however, until 1863. By this time the success of the lines in the Mediterranean and in the Persian Gulf had demonstrated the practicability of long submarine telegraphs, and the public confidence in the attempt had been revived to such an extent that the directors ventured to call for proposals for the manufacture of a cable. Seventeen offers were made, from which that of Messrs. Glass, Elliott & Co., of London, was selected. Mr. Field now renewed his indomitable efforts, and in a few months the new capital of six hundred thousand pounds was subscribed, Messrs. Glass, Elliott &, Co. taking three hundred and fifteen thousand pounds, besides one hundred thousand pounds in bonds. This was accomplished in 1864, and work on the cable was immediately begun. The cable now adopted was very different from, and much more sensitive than, those which had been used before. It was heavier, and less liable to be injured by the water.

The "Great Eastern" steamship, the greatest wonder of naval architecture, was at this time advertised for sale, and it occurred to several of the gentlemen interested in the telegraph company that she was the best vessel for laying the cable that could be found. They at once organized themselves into a company, purchased the ship, and fitted her up for that service. They were fortunate in securing the services of Captain James Anderson, and placing him in charge of her, sent her to Sheerness, where the cable was sent down to her in lighters from the factory at Greenwich. When the cable was on board, and all the other arrangements had been completed, the big ship left the Thames and sailed for Valentia harbor.

The point of landing had been changed from Valentia harbor, five or six miles, to Foilhommerum Bay. On the 23d of July, 1865, the shore end was connected with the cable on board the ship, and the voyage was begun. It would be interesting to follow the huge steamer on this remarkable voyage, and to relate to the reader the almost marvelous manner in which faults were detected in the line hundreds of miles from the shore, and how the cable was successfully hauled in and the damage repaired. All went well until twelve hundred miles of cable had been paid out, and the ship was but six hundred miles from the shores of Newfoundland, when the cable broke again and plunged into the sea.
