Circumstances delayed the construction of a recording telegraph by Morse, but the subject slumbered in his mind. During his absence abroad he had been elected professor of the literature of the arts of design, in the University of the City of New York, and this work occupied his attention for some time. Three years afterward, in November, 1835, he completed a rude telegraph instrument--the first recording apparatus; but it embodied the mechanical principle now in use the world over. His whole plan was not completed until July, 1837, when by means of two instruments he was able to communicate from as well as to a distant point. In September hundreds of people saw the new instrument in operation at the university, most of whom looked upon it as a scientific toy constructed by an unfortunate dreamer. The following year the invention was sufficiently perfected to enable Morse to direct the attention of Congress to it and ask its aid in the construction of an experimental line between Washington and Baltimore. Late in the long session of 1838 he appeared before that body with his instrument. Before leaving New York with it he had invited a few friends to see it work. Now began in the life of Morse a period of years during which his whole time was devoted to convincing the world, first, that his electric telegraph would really communicate messages, and, secondly, that if it worked at all, it was of great practical value. Strange to say that this required any argument at all. But that in those days it did may be inferred from the fact that Morse could then find no help far or near. His invention was regarded as interesting, but of no importance either scientifically or commercially. In Washington, where he first went, he found so little encouragement that he went to Europe with the hope of drawing the attention of foreign governments to the advantages, and of securing patents for the invention; he had filed a caveat at the Patent Office in this country. His mission was a failure. England refused him a patent, and France gave him only a useless paper which assured for him no special privileges. He returned home disappointed but not discouraged, and waited four years longer before he again attempted to interest Congress in his invention. [Illustration: The Modern Morse Telegraph.]
