Read appears to have never succeeded in even experimentally making his plans successful. He deserves credit for his early and intelligent perception of the importance of the subject, and for the ingenuity of his devices. As the inventor of the vertical multi-tubular fire-box boiler, he has also entitled himself to great distinction. This boiler is now in very general use, and is a standard form.

In 1792, Elijah Ormsbee, a Rhode Island mechanic, assisted pecuniarily by David Wilkinson, built a small steamboat at Winsor’s Cove, Narragansett Bay, and made a successful trial-trip on the Seekonk River. Ormsbee used an “atmospheric engine” and “duck’s-foot” paddles. His boat attained a speed of from three to four miles an hour.

In Great Britain, Lord Dundas and William Symmington, the former as the purveyor of funds and the latter as engineer, followed by Henry Bell, were the first to make the introduction of the steam-engine for the propulsion of ships so completely successful that no interruption subsequently took place in the growth of the new system of water-transportation.

Thomas, Lord Dundas, of Kerse, had taken great interest in the experiments of Miller, and had hoped to be able to apply the new motor on the Forth and Clyde Canal, in which he held a large interest. After the failure of the earlier experiments, he did not forget the matter; but subsequently, meeting with Symmington, who had been Miller’s constructing engineer, he engaged him to continue the experiments, and furnished all required capital, about £7,000. This was ten years after Miller had abandoned his scheme.

Symmington commenced work in 1801. The first boat built for Lord Dundas, which has been claimed to have been the “first practical steamboat,” was finished ready for trial early in 1802. The vessel was called the “Charlotte Dundas,” in honor of a daughter of Lord Dundas, who became Lady Milton.

The vessel ([Fig. 75]) was driven by a Watt double-acting engine, turning a crank on the paddle-wheel shaft. The sectional sketch below exhibits the arrangement of the machinery. A is the steam-cylinder, driving, by means of the connecting-rod, B C, a stern-wheel, E E. F is the boiler, and G the tall smoke-pipe. An air-pump and condenser, H, is seen under the steam-cylinder.

In March, 1802, the boat was brought to Lock No. 20 on the Forth and Clyde Canal, and two vessels of 70 tons burden each taken in tow. Lord Dundas, William Symmington, and a party of invited guests, were taken on board, and the boat steamed down to Port Glasgow, a distance of about 20 miles, against a strong head-wind, in six hours.
