[Sidenote: Robert Fulton.] In 1793, Robert Fulton, of whose exertions in the development of steam-engines and their early application to useful purposes[81] the Americans are justly proud, is said to have conceived some time previously the idea of propelling vessels by steam. It was not, however, until 1796 that any of his inventions were brought under notice: when, in that year, his plan for using small canals as a means of transit and for raising and lowering vessels on them by inclined planes was published. In the same year, 1796, it is said that he also suggested and used an apparatus for propelling vessels under water, to be employed in war,[82] but it was not until 1798 that he tried successfully to propel a boat with a steam-engine and a four bladed screw-propeller.[83] That he had shown an early taste for mechanical pursuits there can be no doubt, and, in 1801, when Napoleon contemplated the conquest of England, we know that Fulton made the friendly proposal to convey the legions of French soldiers who were to invade our shores by means of rafts propelled by steam; but, though the Emperor rejected the proposal as chimerical, Fulton, by his intercourse with the French Government, was afforded an opportunity of becoming intimately acquainted with Mr. Livingston, at that time Minister of the United States at Paris, with whom he frequently conversed on the subject of steam navigation, these communications having in the sequel very important results. [Sidenote: And Mr. Livingston.] Mr. Livingston, who had previously been associated with Stevens in the United States in experiments and in various plans for promoting steam navigation, entered readily into the proposals of Fulton, and, on his suggestion, a boat was built on the Seine, the engine for which was ordered in England. This experimental boat, 66 feet long, and 8 feet wide, was completed in 1803. When on the point of making her first trial, the weight of the machinery broke the boat in two and both sank. They were, however, soon raised and the necessary repairs were shortly completed, but, on trial, the boat did not move with as much speed as Mr. Fulton expected. [Sidenote: Plan really derived from English experiments of Symington.] Before describing Fulton’s further experiments, it may be convenient to direct attention to a statement made by Symington soon afterwards in the newspapers of the period, which remains uncontradicted, for the purpose of showing that whatever merit is due to Fulton, his information was derived from others.
