A rugged group of islands belonging to Cornwall, 27 m. SW. of Land's End; consists of six larger islands—St. Mary's (1528 acres, pop. 1200), the largest—and some 30 smaller, besides numerous rock clusters, the name Scilly being strictly applicable to a rocky islet in the NW. of the group; climate is damp and mild; the cultivation and export of large quantities of lilies is the principal industry, but generally industries have decayed, lighthouses have reduced greatly the hereditary occupation of pilotage, and emigration goes on; the only town is Hugh Town (with two hotels, banks, pier, &c.), on St. Mary's; there are some interesting ecclesiastical ruins, &c.; since 1834 much has been done to improve the condition of the islanders by the then proprietor Mr. A. J. Smith, and his nephew, T. A. Darien Smith, who succeeded in 1872.
