James Rumsey was a successful businessman in Bath， Virginia in 1784 when he met George Washington. When the hero of the Revolutionary War stopped in Bath， Rumsey showed Washington his invention. It was a model of a boat using the power of a river’s current（水流）to travel against the current. The boat had a set of wheels with two long poles fastened under the boat. Rumsey placed the boat in the Potomac River and the current turned the wheels round and round quickly， which in turn， forced the poles to push against the riverbed moving the boat against the current.

Washington wrote of the invention in his diary on September 6， 1784， “The model， and its operation upon the water， which had been made to run fast， not only made me believe what I before thought， but that it might be turned to the greatest possible means of transportation.” Washington even gave Rumsey a letter stating that he had seen the boat in operation.

The following year， Washington became president of the Patowmac Company. One of Washington’s first problems was he couldn’t find anyone with experience of building canal. In July 1785， Washington remembered Rumsey’s walking boat and decided that Rumsey was the man to build the canal.

Rumsey had continued his work on the mechanical boat， but a full-scale model had not worked as well as the smaller version. The larger boat’s poles would stick or slip on the bottom of the river and when the boat moved， it lurched（蹒跚）and leaned dangerously.

As making this idea a success seemed to be slipping away， Rumsey turned his sights to a new way to allow a boat to move against the current-steam power. However， Washington employed Rumsey just as he was considering the solution. Washington hired him at an annual salary of 200 pounds.
