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.' The powers of the telegraph having been demonstrated, enthusiasm took the place of apathy, and Morse, who had been neglected before, was in some danger of being over-praised. A political incident spread the fame of the telegraph far and wide. The Democratic Convention, sitting in Baltimore, nominated Mr. James K. Polk as candidate for the Presidency, and Mr. Silas Wright for the Vice-Presidency. Alfred Vail telegraphed the news to Morse in Washington, and he at once told Mr. Wright. The result was that a few minutes later the Convention was dumbfounded to receive a message from Wright declining to be nominated. They would not believe it, and appointed a committee to inquire into the matter; but the telegram was found to be genuine. On April 1, 1845, the Baltimore to Washington line was formally opened for public business. The tariff adopted by the Postmaster-General was one cent for every four characters, and the receipts of the first four days were a single cent. At the end of a week they had risen to about a dollar. Morse offered the invention to the Government for 100,000 dollars, but the Postmaster-General declined it on the plea that its working 'had not satisfied him that under any rate of postage that could be adopted its revenues could be made equal to its expenditures.' Thus through the narrow views and purblindness of its official the nation lost an excellent opportunity of keeping the telegraph system in its own hands. Morse was disappointed at this refusal, but it proved a blessing in disguise. He and his agent, the Hon. Amos Kendall, determined to rely on private enterprise.
