FERNANDO PO or FERNANDO POO, a Spanish island on the west coast of Africa, in the Bight of Biafra, about 20 m. from the mainland, in 3° i 2' N. and 8° 48' E. It is of volcanic origin, related to the Cameroons system of the adjacent main land, is the largest island in the Gulf of Guinea, is 44 m. long from N.N.E. to S.S.W., about 20 m. broad, and has an area of about 810 sq. miles. The shores are steep and rocky and the coast plain narrow. This plain is succeeded by mountain slopes which culminate in the cone of Clarence peak or Pico de Santa Isabel (9,369 ft.), in the north-central part of the island. The Misterio peak in the south is 8,600 feet. There are numerous other peaks between 4,000 and 6,000 ft. high. The mountains contain craters and crater lakes, and are covered, most of them to their summits, with forests. Torrential streams run down the intervening valleys. The forest trees include oil palms and tree ferns, but there are many varieties, embracing ebony, mahogany and the African oak. The undergrowth is dense; it includes the sugar-cane and cotton and indigo plants. The fauna includes an telopes, monkeys, lemurs, the civet cat, porcupine, pythons and green tree-snakes, crocodiles and turtles. The mean temperature on the coast is 78° F and varies little. In the higher altitudes there is considerable daily variation. While the lowlands are very unhealthy, the climate at 2,000 ft. and above is fairly good and in the south temperate. The average annual rainfall is about loo in.; July to October are the wettest months.
The principal settlement is Santa Isabel, otherwise known as Port Clarence (pop. 1,400), a safe and commodious harbour on the north coast.
In Santa Isabel resides the governor of Spanish Guinea, as the Spanish islands in the Gulf of Guinea and, on the mainland, the Muni River settlement, are collectively called. In its graveyard are buried Richard Lander and several other explorers of West Africa. The chief industry until the close of the 19th century was the collection of palm oil ; since then cocoa has become the main product for export.
The administration of the island is in the hands of a governor general, assisted by a council, and responsible to the Direction General de Colonias y Protectorados, a department in the Presi dencia del Consejo (Prime Minister's Office) at Madrid. The governor-general has under his authority the sub-governors of the other Spanish possessions in the Gulf of Guinea, namely, the Muni River Settlement, Corisco and Annobon (qq.v.). None of these possessions is self-supporting. The metropolis contributes two and a half million pesetas (LIoo,000) p.a. to their expenses. In 1926 a special credit of 26,000,000 pesetas was set aside to develop the resources of the islands and mainland territories, to be spent in a period of ten years. The programme includes the construction of roads, harbours, hospitals, schools, health organ ization, telephones and telegraphs and an agricultural school with model farms.
