Steam Navigation. In December, 1736, a patent for a steam-boat was taken out by Jonathan Hull, and a drawing and description of the same was published in the following year. From want of encouragement to the inventor the boat was never constructed. About twenty years later, two Americans, and Thomas Payne, each claimed the honour of inventing steam-boats, but none of the plans were brought into practice. It is believed that the first steamboat ever known to succeed, was the joint invention of Mr. Miller, a Scotchman, and his family tutor, Mr. James Taylor. In 1788 they constructed a boat with paddles, moved by steam-power, which was tried on the lake of Dalswinton, Dumfriesshire, and found to realize the expectations of the inventors. In the following year a larger vessel was constructed, by Mr. Miller, at the Carron Foundry; it was tried on the Forth and Clyde Canal, in November, 1789, and was found to travel at the rate of seven miles an hour. A misunderstanding having occurred between Messrs. Miller and Taylor, Mr. Symington, the maker of the engines in their boats, took up the project, and built another experimental steam-vessel, which was tried with success on the Forth and Clyde Canal, but was interdicted by the Canal Company, on account of its motion destroying the banks. This vessel, while it lay at Lock 16, was inspected by Mr. Fulton, accompanied by Mr. H. Bell, of Glasgow. In 1807, Mr. Fulton launched a steam-vessel on the Hudson; and in 1812, Mr. Bell launched another on the Clyde. These were the first vessels used for the service of the public. Fulton's first vessel was ill-constructed, but he afterwards built vessels with various improvements, and every effort added to their utility and fame. In a few years afterwards steam-boats were generally Introduced, when " every feasible method that ingenuity could suggest towards their improvement was called into action ; till at length the inexhaustible resources of national art and science produced those ocean steamers which float across the Atlantic - the triumph of art, and the admiration of the world."
