Abstract: Nigeria divided for administrative purposes into three regions (northern western and eastern) forming a Protectorate is situated on the northern shore of the Gulf of Guinea and bounded on the west north and east by the French territories of French West Africa French Equatorial Africa and part of the Cameroons under French Trusteeship. It is the largest British dependency in West Africa with a total area of 372674 square miles (964853 km(2)). Along the entire coast of Nigeria is a belt 1-60 miles (1.6-97 km) wide of mangrove swamp forest. Farther inland is a zone 50-100 miles (80-160 km) wide of tropical rain forest. Beyond this zone the vegetation changes to dry forest and farther north to open woodland and to grass savannah interspersed with scrub. In the extreme north desert conditions prevail. Most of the south of the country is less than 1000 feet (300 m) above sea level while most of the north is between 1000 and 2000 feet (300-600 m) above sea level. Nigeria possesses few mountains except along the eastern boundary where the Cameroons mountain rises to 13350 feet (4070 m) and on the central Bauchi plateau which rises to over 6000 feet (1800 m) above sea level. The river Niger enters the territory from the north-west and after flowing nearly 500 miles (800 km) is joined by its principal tributary the Benue at Lokoja about 340 miles (550 km) from the sea. From here it flows due south into its delta which extends for over 100 miles (160 km) along the coast and for about 140 miles (225 km) inland. The Niger has two almost independent floods--in the upper river from July to January and in the lower river in September-October. Second in importance to the river Niger (with its main tributary the Benue) is the river Cross. In southern Nigeria several rivers flow into the coastal creeks and lagoons. In northern Nigeria a few smaller rivers drain from the Bauchi highlands toward the Lake Chad basin. (excerpt)
