How simple it all seems to us now, and yet its very simplicity is its sublimest feature, for it was this which compelled the admiration of scientists and practical men of affairs alike, and which gradually forced into desuetude all other systems of telegraphy until to-day the Morse telegraph still stands unrivalled. That many other minds had been occupied with the same problem was a fact unknown to the inventor at the time, although a few years later he was rudely awakened. A fugitive note, written many years later, in his handwriting, although speaking of himself in the third person, bears witness to this. It is entitled "Good thought":-- "A circumstance which tends to confuse, in fairly ascertaining priority of invention, is that a subsequent state of knowledge is confounded in the general mind with the state of knowledge when the invention is first announced as successful. This is certainly very unfair. When Morse announced his invention, what was the general state of knowledge in regard to the telegraph? It should be borne in mind that a knowledge of the futile attempts at electric telegraphs previous to his successful one has been brought out from the lumber garret of science by the research of eighteen years. Nothing was known of such telegraphs to many scientific men of the highest attainments in the centres of civilization. Professor Morse says himself (and certainly he has not given in any single instance a statement which has been falsified) that, at the time he devised his system, he supposed himself to be the first person that ever put the words 'electric telegraph' together. He supposed himself at the time the originator of the phrase as well as the thing. But, aside from his positive assertion, the truth of this statement is not only possible but very probable. The comparatively few (very few as compared with the mass who now are learned in the facts) who were in the habit of reading the scientific journals may have read of the thought of an electric telegraph about the year 1832, and even of Ronald's, and Betancourt's, and Salva's, and Lomond's impracticable schemes previously, and have forgotten them again, with thousands of other dreams, as the ingenious ideas of visionary men; ideas so visionary as to be considered palpably impracticable, declared to be so, indeed, by Barlow, a scientific man of high standing and character; yet the mass of the scientific as well as the general public were ignorant even of the attempts that had been made. The fact of any of them having been published in some magazine at the time, whose circulation may be two or three thousand, and which was soon virtually lost amid the shelves of immense libraries, does not militate against the assertion that the world was ignorant of the fact. We can show conclusively the existence of this ignorance respecting telegraphs at the time of the invention of Morse's telegraph."
