Those immemorial pathways, the great rivers, were the main avenues of traffic with the interior. So, of course, when men thought of improving transportation, they had in mind chiefly transportation by water; and that is why the earliest efforts of American inventors were applied to the means of improving traffic and travel by water and not by land. The first men to spend their time in trying to apply steam power to the propulsion of a boat were contemporaries of Benjamin Franklin. Those who worked without Watt's engine could hardly succeed. One of the earliest of these was William Henry of Pennsylvania. Henry, in 1763, had the idea of applying power to paddle wheels, and constructed a boat, but his boat sank, and no result followed, unless it may be that John Fitch and Robert Fulton, both of whom were visitors at Henry's house, received some suggestions from him. James Rumsey of Maryland began experiments as early as 1774 and by 1786 had a boat that made four miles an hour against the current of the Potomac. The most interesting of these early and unsuccessful inventors is John Fitch, who, was a Connecticut clockmaker living in Philadelphia. He was eccentric and irregular in his habits and quite ignorant of the steam engine. But he conceived the idea of a steamboat and set to work to make one. The record of Fitch's life is something of a tragedy. At the best he was an unhappy man and was always close to poverty. As a young man he had left his family because of unhappy domestic relations with his wife. One may find in the record of his undertakings which he left in the Philadelphia Library, to be opened thirty years after its receipt, these words: "I know of nothing so perplexing and vexatious to a man of feelings as a turbulent Wife and Steamboat building." But in spite of all his difficulties Fitch produced a steamboat, which plied regularly on the Delaware for several years and carried passengers. "We reigned Lord High Admirals of the Delaware; and no other boat in the River could hold its way with us," he wrote. "Thus has been effected by little Johnny Fitch and Harry Voight [one of his associates] one of the greatest and most useful arts that has ever been introduced into the world; and although the world and my country does not thank me for it, yet it gives me heartfelt satisfaction." The "Lord High Admirals of the Delaware," however, did not reign long. The steamboat needed improvement to make it pay; its backers lost patience and faith, and the inventor gave up the fight and retired into the fastnesses of the Kentucky wilderness, where he died.
