The largest and richest of the Channel Islands, lies 15 m. off the French coast, 100 m. S. of Portland Bill, is oblong in shape, with great bays in the coast, and slopes from the N. to the SW.; the soil is devoted chiefly to pasture and potato culture; the exports are early potatoes for the London market and the famous Jersey cattle, the purity of whose breed is carefully preserved; the island is self-governing, has a somewhat primitive land tenure, is remarkably free from poverty and crime, has been under the English crown since 1066; the capital is St. Helier, where there is a college, a public library, a harbour, and a good market.
