The first two photos show where the old Leavenworth sawmill used to stand on Blind Pond Brook. The two stone walls were built to channel the water to the mill.
A sluice was created utilizing the large vertical posts placed vertically in the brook. Horizontal boards would be raised or lowered against the posts. In this way the flow of water to the waterwheel could be regulated.—The Mill on Halfway Brook, p. 43.
A special thank you to my cousin Cynthia for the photos.
