Manchaug was a mill town for a while. Here are old drawings of the three mills. They are from the Sutton History Volume 1, written in 1878.
Mill #1 - old mill
You can see current photos of Mill #1 on the Manchaug Page
Mill #2 - middle mill
Mill #3 - new mill
Mill #3 again
There was also another mill separate from those 3 - F.B. Smith's Mill
