In January, 1858, the Board of Directors offered Mr. Field the sum of five thousand dollars per annum if he would assume the post of general manager of the company. He at once undertook the duties of the position, but declined all compensation.
Every thing being in readiness for the second attempt at laying the cable, the "Niagara" sailed from New York in March, 1858, to take on her portion of the cable at Plymouth. The "Agamemnon" was again ordered to assist in the undertaking, and the "Gorgon" was made her consort Mr. Field had hoped that the "Susquehanna" would again be the consort of the "Niagara," but a few days before the sailing of the fleet he was officially informed that he could not have the ship, as she was then in the West Indies, with the greater part of her crew down with the yellow fever. This was a keen disappointment, as every arrangement had been made with the expectation of having the assistance of the "Susquehanna." It was too late to ask the Government at Washington for another ship, and it was by no means certain that the request would be granted if made. In this dilemma Mr. Field frankly stated his disappointment to the Lords of the Admiralty of England, and asked for a ship to accompany the "Niagara." He was informed that the English Government was at that moment chartering vessels to convey troops to Malta, as it had not ships enough of its own, and that it was doubtful whether it could contribute a third ship to the expedition. Still, so greatly did the government desire the success of the enterprise, that a little later on the same day the "Valorous" was ordered to take the place of the "Susquehanna" in the telegraph fleet. This generous assistance was all the more praiseworthy, as it was given at a time when the need of England for ships was very urgent.
After shipping the cable, the squadron sailed from Plymouth on the 29th of May, 1868, for the Bay of Biscay, where the cable was subjected to numerous and thorough tests, which demonstrated its strength and its sensitiveness to the electric current. This accomplished, the vessels returned to Plymouth.
