PROFESSOR MORSE AND THE TELEGRAPH.        583

municate intelligence between far distant places out of the line of vision by means of electro-magnetism, and he saw an electromagnetic semaphore in operation. He was aware that so early as 1649, Strada, a Jesuit priest, had in fable prophesied of an electric telegraph; and that for half a century or more, philosophers had been, from time to time, partially succeeding in the discovery of the anxiously-looked for result. But no telegraph proper-no instrument for writing at a distance-had yet been invented.*

In the ship Sully, in which Mr. Morse voyaged from Havre to New York in the autumn of 1832, the recent discovery in France of the means for obtaining the electric spark from a magnet was a fruitful topic of conversation among the cultivated passengers; and it was during the voyage that a revelation was made to the mind of Morse, which enabled him to conceive the idea of an electro-magnetic and chemical recording telegraph, substantially and essentially as it now exists. Before the Sully had reached New York, he had elaborated his conceptions in the form of drawings and specifications, which he exhibited to his fellow-passengers. This fact, proven by the testimony of those passengers given in a court of justice, fixes the date of the invention of Morse's electro-magnetic recording telegraph at the autumn of 1832.

Circumstances delayed the construction of a complete recording telegraph by Mr. Morse, and the subject slumbered in his mind. During his absence abroad he had been elected to the professorship of the Literature of the Arts of Design in the University of the City of New York, and this field of occupied 

*In 1774, Le Sage constructed an electric semaphore with twenty-four wires corresponding to the 24 letters of the alphabet. In 1793, Claude Chappé established an aërial line of electric semaphores. From 1780 to 1800, German, Italian, and Spanish philosophers made interesting experiments in this direction. In 1810 Schweiger discovered the multiplying power of the magnet by an electric coil, and in 1819 Oersted perfected the discovery of electro-magnetism, Ronalds constructed an electric semaphore, which made signals at a distance of eight miles, in 1816. In 1825 Sturgeon invented the electro-magnet. In 1830 Professor Henry applied Schweiger's coil to Sturgeon's magnet, and wonderfully increased the magnetic force which Morse subsequently used. Arago, Faraday, Ampère, Gauss and Weber, and Steinheil had made many valuable advances towards the great discovery, and Wheatstone very nearly reached it.

MORSE'S FIRST RECORDING TELEGRAPH.

his attention for some time. Finally, in November, 1835, he completed a rude telegraphic instrument-the first recording apparatus-which is now in the library of his country-seat near Poughkeepsie. It embodied the mechanical principles of those now in use in every quarter of the globe. But 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 it in operation at the University, the larger portion of whom looked upon it as a scientific toy constructed by an unfortunate dreamer.

In the following year Mr. Morse's invention was sufficiently perfected to induce him to call the attention of the National Congress to it, and ask their aid in the construction of an experimental line between the cities of 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 invited a few friends to see it work. The written invention ran thus,-I copy one now before me:
