"GWITHIAN, a parish in the E. division of the hundred of Penwith, county Cornwall, 7 miles W. of Redruth. The village is situated near the bridge over the river Gwithian, which falls into St. Ives Bay. This parish extends along the coast of the Bristol Channel, and has been partly inundated with shifting shell sand. To protect the village from a similar Me, the sea-rush has been planted in sufficient quantities to bind the loose sand. The subsoil is slate with veins of copper, which was formerly more extensively worked than at present. The tithes have been commuted for a rent-charge of £234 19s. 6d. There are quarries of good building stone, and of a peculiar variety of sandstone, which is used instead of bricks in the construction of chimneys. The living is a rectory annexed to that of Phillack. The church is dedicated to St. Gothian. There is a place of worship for Wesleyans. In the vicinity are extensive earthworks called Trevarnon Rounds."
"GODREVY, a village and low island situated N. of St. Ives Bay, in the parish of Gwithian, county Cornwall, about 9 miles W. of Redruth. It is the property of the Basset family. Off the shore here is a reef that renders the approach to the island somewhat dangerous."
