Near Shawbost, on the northern coast of the Isle of Lewis, James Crawford (with red cap) and his family are re-thatching a two hundred year old watermill. The cornmill was used by local farmers into the 1930s. Its horizontal paddle wheel is housed in the stone structure beneath the thatched roof. These mills are generally called "Norse", an adjective given in the 19th century when people erroneously thought they were a remnant of the Viking occupation of the Hebrides. Photo Mick Palarczyk.
