During the summer of 1842 he insulated a wire two miles long with hempen threads saturated with pitch-tar and surrounded with india-rubber. On October 18, during bright moonlight, he submerged this wire in New York Harbour, between Castle Garden and Governor's Island, by unreeling it from a small boat rowed by a man. After signals had been sent through it, the wire was cut by an anchor, and a portion of it carried off by sailors. This appears to be the first experiment in signalling on a subaqueous wire. It was repeated on a canal at Washington the following December, and both are described in a letter to the Secretary of the Treasury, December 23, 1844, in which Morse states his belief that 'telegraphic communication on the electro-magnetic plan may with certainty be established across the Atlantic Ocean. Startling as this may now seem, I am confident the time will come when the project will be realised.'
In December, 1842, the inventor made another effort to obtain the help of Congress, and the Committee on Commerce again recommended an appropriation of 30,000 dollars in aid of the telegraph. Morse had come to be regarded as a tiresome 'crank' by some of the Congressmen, and they objected that if the magnetic telegraph were endowed, mesmerism or any other 'ism' might have a claim on the Treasury. The Bill passed the House by a slender majority of six votes, given orally, some of the representatives fearing that their support of the measure would alienate their constituents. Its fate in the Senate was even more dubious; and when it came up for consideration late one night before the adjournment, a senator, the Hon. Fernando Wood, went to Morse, who watched in the gallery, 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.'
Morse retired to his rooms, and after paying his bill for board, including his breakfast the next morning, he found himself with only thirty-seven cents and a half in the world. Kneeling by his bed-side he opened his heart to God, leaving the issue in His hands, and then, comforted in spirit, fell asleep. While eating his breakfast next morning, Miss Annie G. Ellsworth, daughter of his friend the Hon. Henry L. Ellsworth, Commissioner of Patents, came up with a beaming countenance, and holding out her hand, 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!'
It had been voted without debate at the very close of the session.
Years afterwards Morse declared that this was the turning-point in the history of the telegraph. 'My personal funds,' he wrote,' were reduced to the fraction of a dollar; and had the passage of the Bill failed from any cause, there would have been little prospect of another attempt on my part to introduce to the world my new invention.'
Grateful to Miss Ellsworth for bringing the good news, he declared that when the Washington to Baltimore line was complete hers should be the first despatch.
The Government now paid him a salary of 2,500 dollars a month to superintend the laying of the underground line which he had decided upon. Professors Gale and Fisher became his assistants. Vail was put in charge, and Mr. Ezra Cornell, who founded the Cornell University on the site of the cotton mill where he had worked as a mechanic, and who had invented a machine for laying pipes, was chosen to supervise the running of the line. The conductor was a five-wire cable laid in pipes; but after several miles had been run from Baltimore to the house intended for the relay, the insulation broke down. Cornell, it is stated, injured his machine to furnish an excuse for the stoppage of the work.
The leaders consulted in secret, for failure was staring them in the face. Some 23,000 dollars of the Government grant were spent, and Mr.
Smith, who had lost his faith in the undertaking, claimed 4000 of the remaining 7000 dollars under his contract for laying the line. A bitter quarrel arose between him and Morse, which only ended in the grave. He opposed an additional grant from Government, and Morse, in his dejection, proposed to let the patent expire, and if the Government would use his apparatus and remunerate him, he would reward Alfred Vail, while Smith would be deprived of his portion. Happily, it was decided to abandon the subterranean line, and erect the conductor on poles above the ground. A start was made from the Capitol, Washington, on April 1, 1844, and the line was carried to the Mount Clare Depot, Baltimore, on May 23, 1843. Next morning Miss Ellsworth fulfilled her promise by inditing the first message. She chose the words, 'What hath God wrought?' and they were transmitted by Morse from the Capitol at 8.45 a.m., and received at Mount Clare by Alfred Vail.
This was the first message of a public character sent by the electric telegraph in the Western World, and it is preserved by the Connecticut Historical Society. The dots and dashes representing the words were not drawn with pen and ink, but embossed on the paper with a metal stylus.
The machine itself was kept in the National Museum at Washington, and on removing it, in 1871, to exhibit it at the Morse Memorial Celebration at New York, a member of the Vail family discovered a folded paper attached to its base. A corner of the writing was torn away before its importance was recognised; but it proved to be a signed statement by Alfred Vail, to the effect that the method of embossing was invented by him in the sixth storey of the NEW YORK OBSERVER office during 1844, prior to the erection of the Washington to Baltimore line, without any hint from Morse. 'I have not asserted publicly my right as first and sole inventor,' he says, 'because I wished to preserve the peaceful unity of the invention, and because I could not, according to my contract with Professor Morse, have got a patent for it.'
