There can be no doubt that Fulton derived his general plan from the experiments of Symington. While that engineer was conducting his experiments under the patronage of Lord Dundas, a stranger came to the banks of the Forth and Clyde Canal and requested an interview, announcing himself as Mr. Fulton, of the United States, whither he intended to return, and expressing a desire to see Mr. Symington’s boat and machinery, and to procure some information of the principles on which it was moved, before he left Europe. He remarked that, however beneficial the invention might be to Great Britain, it would be of more importance to North America, considering the numerous navigable rivers and lakes of that continent, and the facility for procuring timber for building vessels and supplying them with fuel; that the usefulness of steam-vessels in a mercantile point of view could not fail to attract the attention of every observer; and that, if he were allowed to carry the plan to the United States, it would be advantageous to Mr. Symington, as, if his engagements would permit, the constructing or superintending the construction of such vessels would naturally devolve upon him. Mr. Symington, in compliance with the stranger’s request, caused the engine-fire to be lighted, and the machinery put in motion. Several persons entered the boat, and along with Mr. Fulton were carried from where she then lay to Lock No. 16 on the Forth and Clyde Canal, about four miles west, and returned to the starting-place in one hour and twenty minutes, being at the rate of six miles an hour, to the astonishment of Mr. Fulton and the other gentlemen. Mr. Fulton obtained leave to take notes and sketches regarding the boat and engine, “but he never afterwards communicated with Mr. Symington.”(27) He, it has been shown, almost immediately afterwards ordered a marine engine from Messrs. Boulton and Watt, of Soho, near Birmingham. This engine reached America before the _Clermont_, which had been constructed at the instance of Fulton and Livingston, had been launched from the yard of Charles Brown, on the East (Hudson) River. She was decked for a short distance only, at stem and stern, her engines being open to view, while a house on deck, and over the boiler, accommodated passengers and crew. _The boiler was set in masonry._ Her engine was of almost identical size to that of the _Charlotte Dundas_. It is right to add that Fulton claimed no patent or privilege for this engine, which was so evidently founded on that of Symington. Her hull was quite as distinctly his own design, and was vastly superior in build to the Scotch vessel. The first trip of the _Clermont_ was from New York to Clermont, the seat of Mr. Livingston, returning to Albany, and the average speed was five miles per hour. [Illustration: THE “CLERMONT.”]
