or TERCEIRA, one of the largest islands of the Azores, or Western islands, lying in the Atlantic ocean. It is about 40 miles in circumference; and surrounded with craggy rocks, which render it almost inaccessible. The soil is fertile, abounding in corn, wine, and fruits; and they have plenty of cattle to supply the ships which call there. Their principal trade is wood. The inhabitants are lively, addicted to gallantry, and are said to be extremely revengeful. It is subject to Portugal; and Angra is the capital town. W. Long, 27. 1. N. Lat. 28. 45.
