A history of the growth of the steam-engine . gust 20, 1785, addressed a commendatoryletter to an ex-Memher of Congress, William C. Houston, asking him to assist Pitch in securing the aid of the GeneralGovernment. The latter referred the inventor, by a letterof recommendation, to a delegate from New Jersey, Mr.Lambert Cadwalader. With this, and other letters. Fitchproceeded to New York, where Congress then met, andmade his application in proper form. He was unsuccess-ful, and equally so in attempting to secure aid from theSpanish minister, who desired that the profits should besecured, by a monopoly of the invention, to the King ofSpain. Pitch declined further negotiation, determinedthat, if successful at all, the benefit should accrue to hisown countrymen. In September, 1785, Pitch presented to the AmericanPhilosophical Society, at Philadelphia, a model in which hehad substituted an endless chain and floats for the paddle-wheels, with drawings and a descriptive account of hisscheme. This model is shown in the accompanying figure.. Fig. 6T.—Fitchs Model, 1785. In March, 1786, Fitch was granted a patent by theState of New Jersey, for the exclusive right to the naviga-tion of the waters of the State by steam, for 14 years. Amonth later, he was in Philadelphia, seeking a similarpatent from the State of Pennsylvania. He did not at oncesucceed, but in a few days he had formed a company, raised$300, and set about finding a place in which to constructhis engine. Henry Voight, a Dutch watchmaker, a goodmechanic, and a very ingenious man, took an interest in the STEAM-NAVIGATION. 237 company, and with him Fitch set about his work with greatenthusiasm. After making a little model, having a steam-cylinder but one inch in diameter, they built a model boatand engine, the latter having a diameter of cylinder of thi-eeinches. They tried the endless chain, and other methods ofpropulsion, without success, and finally succeeded with a setof oars worked by the engine. In. August, 177
