An additional virtue of the tub mill is that it doesn't require a dam or "fall." It can be constructed by merely seating the horizontal wheel in the path of a stream current.

(b) a horizontal water-wheel with spiral floats; = DANAIDE. Citation: 1858 Simmonds Dict. Trade, Tub-wheel, a peculiar kind of wheel to a water-mill. From this I would guess that a tub mill could be a grist mill with a tub-wheel. From a Google search on the internet I find reference to a Tub Mill (painting) in Great Smokey Mountains National Park. There is also a Tub Mill Run in Somerset County, Pa. Apparently there is also a mill at Old Sturbridge Village in Massachusetts with a tub wheel. The village is reconstructed to ca. 1810. See http://www.osv.org/ for a animated diagram and description of the tub wheel. (Search for "tub mill" there, click on choices then find (Ctrl+F) "tub") Here is part of the text: The tub wheel in its simplest form is just a small undershot wheel mounted horizontally on a vertical axle. This configuration was developed in the early middle ages and was called a Norse wheel. Turned by the impact of a stream of falling water striking its paddles, its efficiency was increased somewhat by building a bottomless wooden tub around it. This tub harnessed more of the potential energy of the water before the water fell below the wheel. The tub wheel is easy to build and maintain, and is fairly dependable. While it is not very efficient and does not generate a great deal of power, its relatively small diameter (usually less than six feet) allows it to operate at moderately high speeds, often eliminating the need for gearing. Sometimes it could be directly connected to the machinery it was to run. Small neighborhood mills often made use of tub wheels in the 18th and 19th centuries. Hope these clues help you.
