Twenty-two volumes of official documents bearing on Bolivar's career were officially published at Caracas in 1826-1833. There are lives by Larrazabal (New York, 1866); Rojas (Madrid, 1883); and Ducoudray-Holstein (Paris, 1831). Two volumes of his correspondence were published in New York in 1866. BOLIVAR, till 1908 a department of Colombia, bounded N. and W. by the Caribbean Sea, E. by the departments of Magdalena and Santander, S. by Antioquia and S.W. by Cauca. It has an area of 27,028 sq. m., composed in great part of low, alluvial plains, densely wooded, but slightly cultivated and unsuited for north European labour. The population, estimated at 323,097 in 1899, is composed largely of mixed races; in some localities the inhabitants of mixed race are estimated to constitute four-fifths of the population. The capital, Cartagena on the Caribbean coast, was once the principal commercial entrepot of Colombia. Other important towns are Barranquilla and Mompox (8000), on the Magdalena river, and Corozal (9000) and Lorica (10,596 in 1902), near the western coast. BOLIVAR, an inland state of Venezuela, lying S. of the Orinoco and Apure, with the Yuruari territory on the E., the Caroni river forming the boundary, and the Amazonas territory and Brazil on the S. Frequent political changes in Venezuela have led to various modifications in the size and outlines of this state, which comprises large areas of uninhabited territory. It is a country of extensive plains (_llanos_) covered in the rainy season with nutritious grass which disappears completely in the dry season, and of great forests and numerous rivers. Its population was given in 1894 as 135,232, but its area has been largely reduced since then. The capital is Ciudad Bolivar, formerly called Angostura, which is situated on the right bank of the Orinoco about 240 m. above its mouth; pop. 11,686. Vessels of light draught easily ascend the Orinoco to this point, and a considerable trade is carried on, the exports being cocoa, sugar, cotton, hides, jerked beef and various forest products. BOLIVIA, an inland republic of South America, once a part of the Spanish vice-royalty of Peru and known as the province of Charcas, or Upper Peru. It is the third largest political division of the continent, and extends, approximately, from 9 deg. 44' to 22 deg. 50' S. lat., and from 58 deg. to 70 deg. W. long. It is bounded N. and E. by Brazil, S. by Paraguay and Argentina, and W. by Chile and Peru. Estimates of area vary widely and have been considerably confused by repeated losses of territory in boundary disputes with neighbouring states, and no figures can be given which may not be changed to some extent by further revisions. Official estimates are 640,226 and 703,633 sq. m., but Supan (_Die Bevolkerung der Erde_, 1904) places it at 515,156 sq. m.
