an island in the British channel, subject to the crown of Great Britain. It is about eight miles in compass, and is separated from Cape la Hogue, in Normandy, by a narrow strait, called the Race of Alderney, which is a very dangerous passage in stormy weather when the two currents meet; otherwise it is safe, and has depth of water for the largest ships. Through this strait the French fleet made their escape after their defeat at La Hogue, in 1692. It is a healthy island, has but one church, is fruitful both in corn and pasture, and is remarkable for a fine breed of cows. The inhabitants, for their greater safety, live together in a town of the same name. The number of houses is said to be 200, and the inhabitants 1300. It has but one harbour, called Crabby, which is at a good distance from the town; and is only fit for small vessels. To the west lie the range of rocks called the Caskets, so dangerous to mariners.
