It was not until Oliver Evans made his improvements in a mill on Red Clay Creek in Delaware. A mill in the early or middle 1700's looked like a mill in the 1600's, 1500's, 1400's, or 1300's. The milling process was very labor intensive, and a mill could not increase its output unless it increased its labor, installed more duplicate machinery.
