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.'
