Miscellanious papers by and about Bushnell. Only two items are in his hand: a letter(1787) claiming land due him as a result of his service in the American Revolution, and a description of a model for a sailing torpedo [1824?]. Papers on his inventions include a letter by Ezra Lee (1815) with an account of Bushnell's submarine and Lee's operation of it in August, 1787 in New York harbor. Also three letters by Joel Abbot (1825)to Bushnell (then known as David Bush) on his attempts to promote Bushnell's naval warning device. Correspondence (1826-1827) between his executor and his heirs, Ezra and Nehemiah Bushnell of Saybrook, Connecticut, includes a final accounting of Bushnell's estate. In the later papers (1881-1956) are four letters to Anson Phelps Stokes with biographical information on Bushnell and publications on his submarine.
