While on a visit to Paris, Fulton was struck with the injury which standing navies of men-of-war inflicted on the mercantile marine, and gave his whole attention, as he says, "to find out the means of destroying such engines of oppression, by some method which would put it out of the power of any nation to maintain such a system, and compel every government to adopt the simple principles of education, industry, and a free circulation of its produce." The means presented itself to his mind in the shape of an explosive shell, called the torpedo, by which any ship of war could be blown to pieces; and for six or seven years he occupied himself in fruitless attempts to get first the government of France, and then that of England, to take up his project. He did not abandon his schemes with regard to steam-vessels, however; but, under the auspices of Mr. Livingstone, the American ambassador, made several experiments. One vessel of considerable size broke through the middle when the engines were placed on board, but a second one was rather more successful, though but a slow rate of movement was attained. His project came under the notice of Napoleon, then First Consul, who did not fail to appreciate its value. "It was," he said, "capable of changing the face of the world;" and he directed a commission to inquire into its merits. Nothing came of it, however. Shortly after, Fulton visited Scotland, and got an introduction to Symington, whom he pressed for a sight of his boat. Symington generously consented, and gave him a short sail on board the steam-tug. Fulton made no concealment of his intention of starting steamboats in his own country, whither he was about to return, and asked Symington to allow him to make a few notes of his observations on board. Symington had no objections; and, therefore, he says, "Fulton pulled out a memorandum book, and after putting several pointed questions respecting the general construction and effect of the machine, which I answered in a most explicit manner, he jotted down particularly everything then described, with his own remarks upon the boat while moving with him on board along the canal." Fulton was very liberal in his promises not to forget his assistance, if he got steamboats established in America; but Symington never heard anything more of him. Fulton was at New York in 1806, and busy getting a steamboat put together. It was a costly undertaking, and he had little spare cash of his own; so he offered shares in the concern to his friends, but no one would have anything to do with so ridiculous a scheme, as they thought. "My friends," says Fulton, "were civil, but shy. They listened with patience to my explanations, but with a settled cast of incredulity on their countenances. I felt the full force of the lamentation of the poet,-- 'Truths would you teach, to save a sinking land, All shun, none aid you, and few understand.'
