or Midullu (the ancient Lesbos), an island of the Grecian Archipelago, belonging to Turkey, and lying off the west coast of Asia Minor. It is about 45 miles in length by 30 in extreme width, and contains an estimated area of 168,320 acres. The island is traversed by wooded hills, beautifully diversified by plains and valleys; while the two inlets Ports Culoni and Lero extend into the land for several miles, almost severing the island into two portions. The soil is excellent, and the climate salubrious; but want of proper irrigation has much impeded farm operations. The principal articles produced are,—olive oil, silk, cotton, fruit, and indifferent wine. Grain is not grown in sufficient quantity to supply the home consumption. The principal towns are Castro, on the S.E. coast, with 10,000 inhabitants; Molivo; and Culoni. Mitylene suffered much in the Greek war of independence, in the course of which it lost nearly the half of its inhabitants. Pop. 40,000, the majority of whom are Turks. (See LESBOS.)
