This is just about the best picture I have ever seen of the Merchant's Mill still intact.
July 4, 1920
The North side of the Merchant's Mill.
"Above the old village of Occoquan are the falls in the creek and utilizing the difference in the level of the water; a flume or race which might be called a small canal was built ever so many years ago to carry water to turn the wheel of a cotton facrory, now a gray and stately ruin and also to turn the wheel of a venerable grist mill."
July 4, 1920

"The village of Occoquan, the old mill town to which the Mary Washington [River Boat] used to run on excursions...was established a town by Act of Virginia legislature January 5, 1804, though it was quite a milling and manufacturing seat before the town was created"
