Cornwall (322), a county in the SW. extremity of England, forming a peninsula between the English and the Bristol Channels, with a rugged surface and a rocky coast, indented all round with more or less deep bays inclosed between high headlands; its wealth lies not in the soil, but under it in its mines, and in the pilchard, mackerel, and other fisheries along its stormy shores; the county town is Bodmin (5), the largest Penzance (12), and the mining centre Truro (11).
