MS (DLC: TJ Papers, 190:33832, 33831); entirely in Fitz’s hand; undated; with drawing on verso of brief covering letter of 12 June 1810 written from Opelousas Church and stating that “A letter necessary to accompany this is transmitted through a different rout, and I imagine will arrive before this does” (RC in DLC; date reworked from 10 June 1810; addressed: “The Honourable, Thomas Jefferson, Late President of the United States Milton Virginia”; endorsed by TJ as a letter of 10 June 1810 received 16 Aug. 1810 and so recorded in SJL); key to letters sent with Fitz to TJ, 10 June 1810.

This representation of Fitz’s machine is as much a model as a drawing, with the sails cut out and hinged. Fitz did not patent his windmill.
