The history and processes of milling - Resilience

The Northeastern area of the United States also produced soft wheat varieties, so stone milling was also used there. In the late 18th century, Oliver Evans invented the first automated mill in the United States that did the work of seven men (Basey 7). It used millstones, had an enormous amount of levers and pulleys, and was very noisy.
