. Bulletin - United States National Museum. Science. invented in 1787 and experimented with the follow- ing year on the Potomac River. The boat was driven by a steam pump on the hydraulic-jet principle and its trials appear to ha\-e been considered successful. Rumsey is usually credited with inv^enting this boat in 1784 but recent research indicates that his first boat was probably mechanically propelled and intended to demonstrate only a mode of propulsion employing setting poles. After Rumsey completed the tests of his steamboat he went to England and obtained backing that permitted him to start con- struction of another boat there. However, he died before it was completed. The boat was tried out on the Thames by his backers but the demonstration did not impress onlookers enough to create any great interest, and nothing developed from this final experiment. Supposed to represent the second boat, built for the Potomac River trials, the model is no more than a rowboat somewhat like a contemporary ship's loiigboat. having a full entrance, a short and heavy run, and a square stern with the rudder hung out- board. The engine and other details arc not in agreement with contemporary descriptions. The authority for the form of the model is unknown. Scale of model is 2 inches to the foot. The model was made in the Museum.
