I have seen the model of Mr. Ramsey's Boats constructed to work against Stream; examined the powers upon which it acts; been eye witness to an actual experiment in running water of some rapidity; and give it as my opinion (altho' I had little faith before) that he has discovered the art of Working Boats by Mechanism and small manual assistance against rapid currants; that the discovery is of vast importance; may be of the greatest usefulness in our land navigation and if it succeeds of which I have no doubt, that the value of it is greatly enhanced by the simplicity of the works; which when seen and explained to, may be executed by the most common Mechanic.
