 Roosevelt's papers came into the possession of Richard S. Cox, his executor, from whom they were obtained in 1828, and from these, with others from the papers of Chancellor Livingston, a case was prepared and submitted to Roger B. Taney, which had been already submitted to William Wirt, and, both opinions being favorable, a suit was about to be begun when the consideration of the great expense involved in its prosecution caused the whole matter to be abandoned.Roosevelt had by this time retired from active life, residing with his family at Skaneateles.In the case submitted for Wirt's opinion, it is said that Fulton never made oath to the application for a patent for vertical wheels over the sides; and that the application itself was signed by another person — a statement that would seem to be corroborated to a great extent by Fulton's own account of his invention in an interview with Benjamin H. Latrobe on February 7, 1809, when the latter was endeavoring to bring about what subsequently took place — a connection between Fulton and Roosevelt in regard to the introduction of steamboats on the western waters.
