BOLIVAR, an inland State of Venezuela, lying south of the Orinoco, with the Delta-Amacuro territory and British Guiana on the east, the Coroni river forming the boundary, and the Amazonas territory and Brazil on the south. Frequent political changes in Venezuela have led to various modifications in the size and out lines of this State, which comprises large areas of uninhabited ter ritory. It is a country of extensive plains (Ilanos) covered in the rainy season with nutritious grass which disappears completely in the dry season, and of great forests and numerous rivers. Its area is 91,891 sq.m. and its population in 1920 was 65,852, and in 1926 the census found 98,258. The capital is Ciudad Bolivar, formerly called Angostura, which is situated on the right bank of the Orinoco about 24om. above its mouth; pop. 19,712. Vessels of light draught easily ascend the Orinoco to this point, and a con siderable trade is carried on, the exports being gold (from the famous El Callao mines), hides, balata and other forest products.
