Being requested to see an experiment made by Mr. James Rumsey's Steam Boat, on Potowmack river, on Tuesday the 11th of December 1787, it was with great pleasure we saw her get under way with upwards of three tons on board, and move against the current at the rate of four miles an hour, by the force of steam, without any external application whatever : We are well informed, and believe, that the machinery at present is very imperfect, and by no means capable of performing what it would do, if completed ; we are persuaded that it may be brought into common and beneficial use, and be of great advantage to navigation, as the machine is simple, light and cheap, and does not occupy a space of more than four feet by two and a half.
