Third. The tendency of its action to rack the vessel, and render it leaky.
Fourth. The expense of maintenance.
Fifth. The irregularity of its motion, and the motion of the water in the boiler and cistern, and of the fuel-vessel in rough water.
Sixth. The difficulty arising from the liability of the paddles and oars to break, if light, and from the weight, if made strong.
Nor have I ever heard of an instance, verified by other testimony than that of the inventor, of a speedy and agreeable voyage having been performed in a steamboat of any construction.
I am well aware that there are still many very respectable and ingenious men who consider the application of the steam-engine to the purpose of navigation as highly important, and as very practicable, especially on the rapid waters of the Mississippi, and who would feel themselves almost offended at the expression of an opposite opinion. And, perhaps, some of the objections against it may be avoided. That founded on the expense and weight of the fuel may not, for some years, exist on the Mississippi, where there is a redundance of wood on the banks; but the cutting and loading will be almost as great an evil.
Scientific men and amateurs all agreed in pronouncing Fulton's scheme impracticable; but he went on with his work, his boat attracting no less attention and exciting no less ridicule than the ark had received from the scoffers in the days of Noah. The steam-engine ordered from Boulton and Watt was received in the latter part of 1806; and in the following spring the boat was launched from the ship-yard of Charles Brown, on the East River. Fulton named her the "Clermont," after the country-seat of his friend and partner, Chancellor Livingston. She was one hundred and sixty tons burthen, one hundred and thirty feet long, eighteen feet wide, and seven feet deep. Her engine was made with a single cylinder, two feet in diameter, and of four feet stroke; and her boiler was twenty feet long, seven feet deep, and eight feet broad. The diameter of the paddle-wheels was fifteen feet, the boards four feet long, and dipping two feet in the water. The boat was completed about the last of August, and she was moved by her machinery from the East River into the Hudson, and over to the Jersey shore. This trial, brief as it was, satisfied Fulton of its success, and he announced that in a few days the steamer would sail from New York for Albany. A few friends, including several scientific men and mechanics, were invited to take passage in the boat, to witness her performance; and they accepted the invitation with a general conviction that they were to do but little more than witness another failure.
Monday, September 10, 1807, came at length, and a vast crowd assembled along the shore of the North River to witness the starting. As the hour for sailing drew near, the crowd increased, and jokes were passed on all sides at the expense of the inventor, who paid little attention to them, however, but busied himself in making a final and close inspection of the machinery. Says Fulton, "The morning I left New York, there were not, perhaps, thirty persons in the city who believed that the boat would ever move one mile per 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."
One o'clock, the hour for sailing, came, and expectation was at its highest. The friends of the inventor were in a state of feverish anxiety lest the enterprise should come to grief, and the scoffers on the wharf were all ready to give vent to their shouts of derision. Precisely as the hour struck, the moorings were thrown off, and the "Clermont" moved slowly out into the stream. Volumes of smoke and sparks from her furnaces, which were fed with pine wood, rushed forth from her chimney, and her wheels, which were uncovered, scattered the spray far behind her. The spectacle she presented as she moved out gradually from her dock was certainly novel to the people of those days, and the crowd on the wharf broke into shouts of ridicule. Soon, however, the jeers grew silent, for it was seen that the steamer was by degrees increasing her speed. In a little while she was fairly under weigh, and making a steady progress up the stream at the rate of five miles per hour. The incredulity of the spectators had been succeeded by astonishment, and now this feeling gave way to undisguised delight, and cheer after cheer went up from the vast throng. Many people followed the boat for some distance up the river shore. In a little while, however, the boat was observed to stop, and the enthusiasm of the people on the shore at once subsided. The scoffers were again in their glory, and unhesitatingly pronounced the boat a failure. Their chagrin may be imagined when, after a short delay, the steamer once more proceeded on her way, and this time even more rapidly than before. Fulton had discovered that the paddles were too long, and took too deep a hold on the water, and had stopped the boat for the purpose of shortening them.
Having remedied this defect, the "Clermont" continued her voyage during the rest of the day and all night, without stopping, and at one o'clock the next day ran alongside the landing at Clermont, the seat of Chancellor Livingston. She lay there until nine the next morning, when she continued her voyage toward Albany, reaching that city at five in the afternoon, having made the entire distance between New York and Albany (one hundred and fifty miles) in thirty-two hours of actual running time, an average speed of nearly five miles per hour. On her return trip, she reached New York in thirty hours running time—exactly five miles per hour. Fulton states that during both trips he encountered a head wind.
