I am the more minute in adducing this evidence of priority of invention to you, sir, since I have frequently been charged by Europeans, in my own country, with merely imitating long known European inventions. It is, therefore due to my own country, as well as to myself, that in this matter the facts should be known.
Professor Steinheil’s telegraph is the only European telegraph that professes to write the intelligence. He records, however, by the delicate touch of the needle in its deflections, with what practical effect I am unable to say; but I should think that it was too delicate and uncertain, especially as compared with the strong and efficient power which may be produced in any degree by the electro magnet.
I have devoted many years of my life to this invention, sustained in many disappointments by the belief that it is destined eventually to confer immense benefits upon my country and the world.
I am persuaded that whatever facilitates intercourse between the different portions of the human family will have the effect, under guidance of sound moral principles, to promote the best interests of man. I ask of Congress the means of demonstrating its efficiency.
I remain, sir, with great respect, your most obedient servant,
SAM. F. B. MORSE.
Hon. Charles G. Ferris,
Member of the House of Representatives from the city of New York and one of the Committee on Commerce, to whom was referred the subject of the expediency of adopting a system of electro magnetic telegraphs for the United States.
