SCARBA, an island, in the parish of Jura-and-Colonsay, district of Islay, county of Argyll. This island, which is separated from the northern extremity of the isle of Jura by the gulf of Coryvreckan, is about three miles in length and nearly of equal breadth, comprising an area of eight square miles. Its surface is mountainous and rocky, and, towards the west, rises from the Atlantic in abrupt and rugged precipices many hundred feet in height. The cast side is indented by a beautifid semicircular bay, from which the shore ascends in rapid acclivities, interspersed with rocks, and crowned with considerable tracts of birch and alder, presenting a strikingly romantic appearance. The gulf of Coryvreckan, which is about a mile and three-quarters in breadth, has in stormy weather a terrific aspect. Exposed to all the fury of the Atlantic on the west, it forms a dangerous wliirljjool fatal to small vessels at all times, and frc(|uently to vessels of large burthen.
