On the second of September, 1837, the author, with several others, witnessed the first exhibition of this electric telegraph, and soon after became a partner with the inventor. Immediate steps were taken for constructing an instrument for the purpose of exhibiting its powers before the members of Congress. This was done at the Speedwell Iron Works, Morristown, N.J. and exhibited in operation with a circuit of two miles. A few days after, it was again exhibited at the University of the City of New York, for several days, to a large number of invited ladies and gentlemen. The circuit at this time was increased to ten miles. Immediately after this exhibition the instruments and ten miles of wire were taken to Washington, and continued in operation for several months, in the room of the Committee on Commerce at the capitol. Its history and progress, after this period, may be gathered from the preceding documents, printed by order of Congress. _Schilling Electric Telegraph._ We make the following extract in relation to Schilling’s telegraph from the Polytechnic Central Journal, Nos. 31, 32, 1838: “Baron Schilling, of Caunstadt, a Russian Counsellor of State, likewise occupied himself with telegraphs by electricity, (see Allgem Bauztg, 1837, No. 52, p. 440,) and had the merit of having presented a much simpler contrivance, and of removing some of the difficulties of the earlier plans. He reckoned many variations to the right, or left, following in a certain order for a telegraphic sign, as, indeed, in this manner, the needle was strongly varied, and only came to rest gradually, after many repeated vibrations; he introduced a small rod of platinum, with a scoop, which dipped into a vessel of quicksilver, placed beneath the needle, and by the check given, changed the vibration of the needle into sudden jerks. In order to apprise the attendant of a telegraphic despatch, he loosed an alarm. How much of this contrivance was Schilling’s own, or whether a portion of it was not an imitation of Gauss and Weber, the author cannot decide, but that Schilling had already experimented, probably with a more imperfect apparatus, before the Emperor Alexander, and still later before Emperor Nicholas, is affirmed by the documents quoted.” From the report of the “Academy of Industry,” Paris, February, 1839, we make the following extract, in relation to the same subject:
