Besides the evidence these testimonials furnish of the excellence of Professor Morse’s system, your committee, as well as the greater part of the members of both Houses of Congress, have had a practical demonstration of the operation of the electro magnetic telegraph, and have witnessed the perfect facility and extraordinary rapidity with which a message can be sent by means of it from one extremity of the capitol to the other. This rapidity is not confined in its effects to a few hundred feet, but science makes it certain that the same effects can be produced, at any distance on the globe, between any two given points connected by the conductors. Your committee have alluded to other electric telegraphs; for, as is not uncommon in the birth of great inventions, scientific minds have, at nearly the same period of time, in various parts of Europe, conceived and planned electric telegraphs; but it is a matter of national pride, that the invention of the _first electro magnetic telegraph_, by Professor Morse, as well as the _first conception_ of using electricity as the means of transmitting intelligence, by Doctor Franklin, is the offspring of American genius. Your committee beg leave to refer to the letter of Professor Morse, (marked 13,) in the appendix, to C. G. Ferris, one of the committee, giving, at his request a brief history of the telegraph since it was before Congress, in 1838, for some interesting information concerning it, and for Professor Morse’s estimate of the probable expense of establishing his system of telegraphs for thirty or forty miles. They would also refer to the House document, No. 15, (December 6, 1837,) and to House report, No. 753, (April 6, 1838,) for valuable information on the subject of telegraphs.
