In the spring of 1807, Fulton's first American boat was launched from the shipyard of Charles Brown, on the East River. The engine from England was put on board, and in August she was completed, and was moved by her machinery from her birthplace to the Jersey shore. Livingston and Fulton had invited many of their friends to witness the first trial, among them Dr. Mitchell and Dr. M'Neven, to whom we are indebted for some account of what passed on this occasion. Nothing could exceed the surprise and admiration of all who witnessed the experiment. The minds of the most incredulous were changed in a few minutes. Before the boat had gone a quarter of a mile, the greatest unbeliever must have been converted. The man who, while he looked on the expensive machine, thanked his stars that he had more wisdom than to waste his money on such idle schemes, changed his mind as the boat moved from the wharf and gained speed, and his complacent expression gradually stiffened into one of wonder. This boat, which was called the Clermont, soon after made a trip to Albany. Fulton gives the following account of this voyage in a letter to his friend, Mr. Barlow: [Illustration: Departure of the Clermont on her First Voyage.] "My steamboat voyage to Albany and back, has turned out rather more favorable than I had calculated. The distance from New York to Albany is one hundred and fifty miles; I ran it up in thirty-two hours, and down in thirty. I had a light breeze against me the whole way, both going and coming, and the voyage has been performed wholly by the power of the steam-engine. I overtook many sloops and schooners beating to windward, and parted with them as if they had been at anchor. The power of propelling boats by steam is now fully proved. The morning I left New York there were not, perhaps, thirty persons in the city who believed that the boat would even move one mile an hour, or be of the least utility; and while we were putting off from the wharf, which was crowded with spectators, I heard a number of sarcastic remarks. This is the way in which ignorant men compliment what they call philosophers and projectors. Having employed much time, money, and zeal, in accomplishing this work, it gives me, as it will you, great pleasure to see it fully answer my expectations. It will give a cheap and quick conveyance to the merchandise on the Mississippi, Missouri, and other great rivers, which are now laying open their treasures to the enterprise of our countrymen; and although the prospect of personal emolument has been some inducement to me, yet I feel infinitely more pleasure in reflecting on the immense advantage that my country will derive from the invention."
