"You say, 'I trust you will take care that the proper share of credit shall be given to me when you make public your doings.' This I always have done and with pleasure. I have always given you credit for great genius and acquirements, and have always said, in giving any account of my Telegraph, that it was during a scientific conversation with you on board the ship that I first conceived the thought of an electric Telegraph. Is there really any more that you will claim or that I could in truth and justice give?

"I have acknowledgments of a similar kind to make to Professor Silliman and to Professor Gale; to the former of whom I am under precisely similar obligations with yourself for several useful hints; and to the latter I am most of all indebted for substantial and effective aid in many of my experiments. If any one has a claim to be considered as a mutual inventor on the score of aid by hints, it is Professor Gale, but he prefers no claim of the kind."

And he never did prefer such a claim (although it was made for him by others), but remained always loyal to Morse. Jackson, on the other hand, insisted on pressing his demand, although it was an absurd one, and he was a thorn in the flesh to Morse for many years. It will not be necessary to go into the matter in detail, as Jackson was, through his wild claims to other inventions and discoveries, thoroughly discredited, and his views have now no weight in the scientific world.

The third person who came to the assistance of Morse at this critical period was Alfred Vail, son of Judge Stephen Vail, of Morristown, New Jersey. In 1837 he was a young man of thirty and had graduated from the University of the City of New York in 1836. He was present at the exhibition of Morse's invention on the 2d of September, 1837, and he at once grasped its great possibilities. After becoming satisfied that Morse's device of the relay would permit of operation over great distances, he expressed a desire to become associated with the inventor in the perfecting and exploitation of the invention. His father was the proprietor of the Speedwell Iron Works in Morristown, and young Vail had had some experience in the manufacture of mechanical appliances in the factory, although he had taken the theological course at the University with the intention of entering the Presbyterian ministry. He had abandoned the idea of becoming a clergyman, however, on account of ill-health, and was, for a time, uncertain as to his future career, when the interest aroused by the sight of Morse's machine settled the matter, and, after consulting with his father and brother, he entered into an agreement with Morse on the 23d day of September, 1837.

In the contract drawn up between them Vail bound himself to construct, at his own expense, a complete set of instruments; to defray the costs of securing patents in this country and abroad; and to devote his time to both these purposes. It was also agreed that each should at once communicate to the other any improvement or new invention bearing on the simplification or perfecting of the telegraph, and that such improvements or inventions should be held to be the property of each in the proportion in which they were to share in any pecuniary benefits which might accrue.

As the only way in which Morse could, at that time, pay Vail for his services and for money advanced, he gave him a one-fourth interest in the invention in this country, and one half in what might be obtained from Europe. This was, in the following March, changed to three sixteenths in the United States and one fourth in Europe.

Morse had now secured two essentials most necessary to the rapid perfection of his invention, the means to purchase materials and an assistant more skilled than he in mechanical construction, and who was imbued with faith in the ultimate success of the enterprise. Now began the serious work of putting the invention into such a form that it could demonstrate to the skeptical its capability of performing what was then considered a miracle. It is hard for us at the present time, when new marvels of science and invention are of everyday occurrence, to realize the hidebound incredulousness which prevailed during the first half of the nineteenth century. Men tapped their foreheads and shook their heads in speaking of Morse and his visionary schemes, and deeply regretted that here was the case of a brilliant man and excellent artist evidently gone wrong. But he was not to be turned from his great purpose by the jeers of the ignorant and the anxious solicitations of his friends, and he was greatly heartened by the encouragement of such men as Gale and Vail. They all three worked over the problems yet to be solved, Morse going backwards and forwards between New York and Morristown. That both Gale and Vail suggested improvements which were adopted by Morse, can be taken for granted, but, as I have said before, to modify or elaborate something originated by another is a comparatively easy matter, and the basic idea, first conceived by Morse on the Sully, was retained throughout.

All the details of these experiments have not been recorded, but I believe that at first an attempt was made to put into a more finished form the principle of the machine made by Morse, with its swinging pendulum tracing a waving line, but this was soon abandoned in favor of an instrument using the up-and-down motion of a lever, as drawn in the 1832 sketch-book. In other words, it was a return to first principles as thought out by Morse, and not, as some would have us believe, something entirely new suggested and invented independently by Vail.

It was rather unfortunate and curious, in view of Morse's love of simplicity, that he at first insisted on using the dots and dashes to indicate numbers only, the numbers to correspond to words in a specially prepared dictionary. His arguments in favor of this plan were specious, but the event has proved that his reasoning was faulty. His first idea was that the telegraph should belong to the Government; that intelligence sent should be secret by means of a kind of cipher; that it would take less time to send a number than each letter of each word, especially in the case of the longer words; and, finally, that although the labor in preparing a dictionary of all the most important words in the language and giving to each its number would be great, once done it would be done for all time.

I say that this was unfortunate because the fact that the telegraphic alphabet of dots and dashes was not used until after his association with Vail has lent strength to the claims on the part of Vail's family and friends that he was the inventor of it and not Morse. This claim has been so insistently, and even bitterly, made, especially after Morse's death, that it gained wide credence and has even been incorporated in some encyclopedias and histories. Fortunately it can be easily disproved, and I am desirous of finally settling this vexed question because I consider the conception of this simplest of all conventional alphabets one of the grandest of Morse's inventions, and one which has conferred great good upon mankind. It is used to convey intelligence not only by electricity, but in many other ways. Its cabalistic characters can be read by the eye, the ear, and the touch.
