Scope and Content Lade and waterwheel, Boloquoy Steading and Mill, Sanday, Orkney Islands This early to mid-19th-century farm complex with its meal mill and parallel byre range are significant survivors of a working farm. In 1996 when this photograph was taken, Boloquoy housed the last working, oil-powered threshing machine on Sanday. This shows the lade and waterwheel viewed from the south. The water which turned the wheel came down the concrete-lined lade from a mill-pond located to the south-east of the mill. The wheel is undershot, as the water hits the wooden floats from below rather than above, turning the wheel clockwise, that is, against the flow of water. The waterwheel is the simplest form of turbine and can be overshot, where the water pours over the wheel from the top or undershot where the water runs under the wheel. In both cases power is derived from the action of water turning the blades. Source: RCAHMS contribution to SCRAN.
