While Morse had been in Paris, in 1839, he had heard of Daguerre, who had discovered the method of fixing the image of the camera, which feat was then creating a great sensation among scientific men. Professor Morse was anxious to see the results of this discovery before leaving Paris, and the American consul, Robert Walsh, arranged an interview between the two inventors. Daguerre promised to send to Morse a copy of the descriptive publication which he intended to make so soon as a pension he expected from the French Government for the disclosure of his discovery should be secured. He kept his promise, and Morse was probably the first recipient of the pamphlet in this country. From the drawings it contained he constructed the first photographic apparatus made in the United States, and from a back window in the University Building he obtained a good representation of the tower of the Church of the Messiah on Broadway. This possesses an historical interest as being the first photograph in America. It was on a plate the size of a playing-card. With Professor J.W. Draper, in a studio built on the roof of the University, he succeeded in taking likenesses of the living human face. His subjects were compelled to sit fifteen minutes in the bright sunlight, with their eyes closed, of course. Professor Draper shortened the process and was the first to take portraits with the eyes open.
At the session of Congress of 1842-1843 Morse again appeared with his telegraph, and on February 21, 1843, John P. Kennedy, of Maryland, moved that a bill appropriating $30,000, to be expended, under the direction of the Secretary of the Treasury, in a series of experiments for testing the merits of the telegraph, should be considered. The proposal met with ridicule. Johnson, of Tennessee, moved, as an amendment, that one-half should be given to a lecturer on mesmerism, then in Washington, to try mesmeric experiments under the direction of the Secretary of the Treasury; and Mr. Houston said that Millerism ought to be included in the benefits of the appropriation. After the indulgence of much cheap wit, Mr. Mason, of Ohio, protested against such frivolity as injurious to the character of the House and asked the chair to rule the amendments out of order. The chair (John White, of Kentucky) ruled the amendments in order because "it would require a scientific analysis to determine how far the magnetism of the mesmerism was analogous to that to be employed in telegraphy." This wit was applauded by peals of laughter, but the amendment was voted down and the bill passed the House on February 23d by the close vote of 89 to 83. In the Senate the bill met with neither sneers nor opposition, but its progress was discouragingly slow. At twilight on the last evening of the session (March 3, 1842) there were one hundred and nineteen bills before it. It seemed impossible for it to be reached in regular course before the hour of adjournment should arrive, and Morse, who had anxiously watched the dreary course of business all day from the gallery of the Senate chamber, went with a sad heart to his hotel and prepared to leave for New York at an early hour the next morning. His cup of disappointment seemed to be about full. With the exception of Alfred Vail, a young student in the University, through whose influence some money had been subscribed in return for a one-fourth interest in the invention, and of Professor L.D. Gale, who had shown much interest in the work and was also a partner in the enterprise, Morse knew of no one who seemed to believe enough in him and his telegraph to advance another dollar.
As he came down to breakfast the next morning a young lady entered and came forward with a smile, exclaiming, "I have come to congratulate you." "Upon what?" inquired the professor. "Upon the passage of your bill," she replied. "Impossible! Its fate was sealed last evening. You must be mistaken." "Not at all," answered the young lady, the daughter of Morse's friend, the Commissioner of Patents, H.L. Ellsworth; "father sent me to tell you that your bill was passed. He remained until the session closed, and yours was the last bill but one acted upon, and it was passed just five minutes before the adjournment. And I am so glad to be able to be the first one to tell you. Mother says you must come home with me to breakfast."
Morse, overcome by the intelligence, promised that his young friend, the bearer of these good tidings, should send the first message over the first line of telegraph that was opened.
He writes to Alfred Vail that day: "The amount of business before the Senate rendered it more and more doubtful, as the session drew to a close, whether the House bill on the telegraph would be reached, and on the last day, March 3, 1843, I was advised by one of my Senatorial friends to make up my mind for failure, as he deemed it next to impossible that it could be reached before the adjournment. The bill, however, was reached a few minutes before midnight and passed. This was the turning point in the history of the telegraph. My personal funds 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."
The appropriation by Congress having been made, Morse went to work with energy and delight to construct the first line of his electric telegraph. It was important that it should be laid where it would attract the attention of the government, and this consideration decided the question in favor of a line between Washington and Baltimore. He had as assistants Professor Gale and Professor J.C. Fisher. Mr. Vail was to devote his attention to making the instruments and the purchase of materials. Morse himself was general superintendent under the appointment of the government and gave attention to the minutest details. All disbursements passed through his hands. In point of accuracy, the preservation of vouchers, and presentation of accounts, General Washington himself was not more precise, lucid, and correct. Ezra Cornell, afterward one of the most successful constructors of telegraph lines, was employed to take charge of the work under Morse. Much time and expense were lost in consequence of following a plan for laying the wires in a leaden tube, and it was only when it was decided to string them on posts that work began to proceed rapidly.
In expectation of the meeting of the National Whig Convention, May 1, 1844, to nominate candidates for President and Vice-President, energy was redoubled, and by that time the wires were in working order twenty-two miles from Washington toward Baltimore. The day before the convention met, Professor Morse wrote to Vail that certain signals should mean the nomination of a particular candidate. The experiment was approaching its crisis. The convention assembled and Henry Clay was nominated by acclamation to the Presidency. The news was conveyed on the railroad to the point reached by the telegraph and thence instantly transmitted over the wires to Washington. An hour afterward passengers arriving at the capital, and supposing that they had brought the first intelligence, were surprised to find that the announcement had been made already and that they were the bearers of old news. The convention shortly afterward nominated Frelinghuysen as Vice-President, and the intelligence was sent to Washington in the same manner. Public astonishment was great and many persons doubted that the feat could have been performed. Before May had elapsed the line reached Baltimore.
