Andros, an island of the Bahamas, giving name to a small group of islands which are but thinly inhabited, and the passages between which are intricate and difficult. The main island, 20 m. W. of New Providence, is of irregular shape, 65 m. long and 45 m. wide. It is chiefly composed of salt-water marshes and fresh-water swamps, in which there are a few elevated oases bearing excellent cedar timber. It has a population of about 800, nearly all colored, a school, and the privilege of sending one member to the Bahamas assembly.
