Thomas Ellicott (1738-1799) did indeed write and include drawings in his section "The Practical Millwright" which was combined into Oliver Evans'
Young Mill-wright and Miller's Guide, 1795. Ellicott was listed in the subscribers list at the end of the book for buying 150 copies at $2 each; and also wrote a 10 page article about his new mill in Occoquon, Va in the journal
Repertory of Arts and Manufactures, London: 1796. Thomas Ellicott was not involved in the mills in Maryland started by his brothers and now called Ellicott City.
