For Fulton soon realised that he had made his hull insufficiently strong for the weight of the machinery. This is the truth of the incident, and not that jealous enemies had maliciously sunk her, nor that Fulton had himself sent her to the bottom through the lack of appreciation which Napoleon’s Commissioners were exhibiting. This is confirmed by an eyewitness of the event, named Edward Church. But Fulton soon set to work to get his ship built more strongly, and by July of the same year she was ready for her trials. A contemporary account, in describing the strange sight which was witnessed on August 9, 1803, says that at six o’clock in the evening, “aided by only three persons,” the boat was set in motion, “with two other boats attached behind it, and for an hour and a half he [Fulton] produced the curious spectacle of a boat moved by wheels, like a chariot, these wheels being provided with paddles or flat plates, and being moved by a fire-engine.” The same account prophesies great things for the invention and that it will confer great benefits on French internal navigation: for, by this means, whereas it then required four months for barges to be towed from Nantes to Paris, the new method would cause them to do the distance in ten or fifteen days. Very quaintly this account speaks of the existence behind the paddle-wheels of “a kind of large stove with a pipe, as if there were some kind of a small fire-engine intended to operate the wheels of the boat!” These experiments were made in the vicinity of the Chaillot Quay in the presence of many people, including Périer and some of the leading Parisian _savants_, and the boat was found to steam at a rate of 3¼ miles per hour. It is therefore both inaccurate and unjust to dismiss, as at least one writer has done, Fulton’s achievements on the Seine in one line by referring to them as unsuccessful and merely experimental. True, this vessel did not show that amount of speed which Fulton had hoped to get out of her, but she was very far from being a failure. Fulton had left nothing to chance, and the misfortune of the weakness of his first hull and the error in the speed actually obtained were the results rather of inexperience than of carelessness. It is difficult to-day, when we are in possession of so much valuable knowledge connected with naval architecture and marine propulsion, to realise that these early experimenters were feeling in the dark for an object they had never seen. At one time Fulton had estimated that a steamboat could be driven at a rate of sixteen to twenty-four miles an hour, but he found that so much power was lost in getting a purchase on the water that he altered his opinion and put forward the speed of five or six miles as the utmost limit which could be obtained by any boat using the best engines then in existence.
