See if you can find a copy of: Howell, Charles, and Keller, Allan. The Mill at Philipsburg Manor and a Brief History of Milling. Tarrytown, New York: Sleepy Hollow Restorations, 1977. I find it the best brief account of watermill construction and use. >>> [log in to unmask] 02/04/03 05:05PM >>> I am working on mill deeds from the 1815 period and have come across the term "Mill Irons" in connection to a small rural grist mill.
