Shortly after the completion of the line the National Democratic Convention, which nominated Polk and Dallas for President and Vice-President, assembled in Baltimore [May, 1844].  Reports of the convention proceedings were promptly telegraphed to the capital city, where the telegraph office was thronged with Members of Congress interested in the news.  These reports created an immense sensation in Washington and speedily removed all doubts as to the practical success of the new system of communication.  A despatch from the Honorable Silas Wright, then United States Senator from New York, refusing to accept the nomination for Vice-President, was read in the National Convention and produced an extraordinary interest from the fact that very few of the delegates had ever heard of the telegraph, and it required much explanation to satisfy them of the genuineness of the alleged communication.

Having thus established beyond all reasonable question the practical utility of the telegraph as a superior means of public and private communication, Professor Morse and his associates offered their patents to the United States Government for the very moderate price of one hundred thousand dollars, with a view of having the system adopted for general use in connection with the postal establishment.  This proposition was referred to the Postmaster-General for consideration and report.  After due deliberation that officer reported that “Although the invention is an agent vastly superior to any other ever devised by the genius of man, yet the operation between Washington and Baltimore has not satisfied me that, under any rate of postage that can be adopted, its revenues can be made to cover its expenditures.”  Under the influence of this report Congress very naturally declined the offer of the patentees, and the telegraph was thereupon relegated to the domain of private enterprise.  The result was that the patentees finally realized for their interests many times the amount of their offer to the Government.

During the autumn of 1844 short exhibition lines were erected in Boston and New York, for the purpose of familiarizing business men of those cities with the characteristics of the new invention, but they attracted little attention and the promoters had much cause of discouragement on account of public indifference.  For the purpose of arousing more attention to the system, appeals were made to the public press for favorable notice, which were also generally declined.  The proprietor of one of the most prominent and enterprising of the New York daily papers distinctly refused to encourage the establishment of telegraph lines, for the reason, as he freely acknowledged, that if the new method of transmitting intelligence were to come into general use his competitors could use it as well as himself, and he would therefore be deprived of his present advantage over them for procuring early news by the use of an expensive system of special despatch then maintained by his paper.  Two years later he refused to join other papers in receiving the Governor’s message by telegraph from Albany, and was so badly beaten by his rivals in this instance that his paper was thenceforward one of the most generous patrons of the telegraph.
