ORANGE FREE STATE, an inland province of the Union of South Africa. It is divided from Natal by the Drakenberg, from Basutoland by the Caledon river, from the Transvaal by the Vaal river and from the Cape of Good Hope by the Orange river, and in the west by a line drawn across the veld from the Orange to the Vaal. It lies between 3o' and 4o' S. and between 1o' and 4o' E. Its area is 49,647 sq. miles.
The country forms part of the inner plateau of South Africa, and most of it lies between 4,000 and 5,000 ft. above sea level.
From the mountainous, eastern districts it slopes gradually west ward, no natural boundary marking its western frontier. The aspect of the country is that of vast, undulating, treeless plains, with a certain number of willows and thorn trees along the streams.
The latter were formerly more widely spread, but have nearly all been cut down for fuel. The Australian black wattle, gums and the pepper tree have been successfully introduced and are grown along the streets of the towns, and in plantations on farms, especially in the eastern districts, to provide shelter, poles and firewood. The general level of the surface is broken by low ridges, and isolated table mountains, the latter attaining considerable elevation above the plain. They are particularly numerous and well developed in the east, and are due to the outcrop of beds of sandstones and dolerites. The rivers, except the Orange, Vaal and Caledon, are dry or nearly dry, for three or four months dur ing the dry winter season, but after rain even the small spruits may become raging torrents. (For geology, climate, flora and fauna, see SOUTH AFRICA, UNION OF.) Population.—In 1931 the white population numbered 205,375. The corresponding figures are not available for others than the European elements, but in 1921 their numbers amounted to 421, 306 natives, 395 Asiatics and 17,898 mixed and others. The largest element among the natives is probably the Basuto, who are largely represented in the districts of Harrismith, Bethlehem, Ficksburg and Ladybrand. A considerable number of Barolong live in the districts of Thaba'nchu and Bloemfontein, and the Amazulu are well represented chiefly in the north-eastern area, adjoining Zulu land. Other tribes include Fingoes, Ama-xosa, etc. The popula
tion of the country as a whole, which amounts to 9.08% of the Union, and which has an average density of 12.67 per sq. m., is concentrated in the eastern and better-watered districts.
