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.
He came to the front in the war of independence against Spain, and his military career, which began about 1810, was distinguished by the defeat of the Spanish forces at Mata de la Miel (1815), at Montecal and throughout the province of Apure (1816), and at Puerto Cabello (1823).
It consists of two portions - a vast, hilly or mountainous area, densely wooded, in the south-east and south, and level plains in the north-west between the Orinoco and the Apure and the mountains.
As far as Calabozo (about one-third of the distance between the hills and the Apure) it was now chaparros (Curatella americana), now mimosas, which were the prevailing feature of the landscape.
The Orinoco is supposed to have 436 tributaries, of which, among the largest, the Caroni-Paragua, Aro, Caura, Cuchivero, Suapure, Sipapo and Ventuari have their sources in the Guiana highlands; the Suata, Manapere and Guaritico in the northern sierras; and the Apure, Uricana, Arauca, Capanaparo, Meta, Vichada and Guaviare (the last three being Colombian rivers) in the llanos and Andes.
The Apure receives two large tributaries from the northern sierras - the Guarico and Portuguesa.
This mass also forms the bed of the Orinoco from its junction with the Apure nearly to its mouth, and it probably extends northwards for some distance beneath the more recent deposits of the plain.
A regular service is maintained on Lake Maracaibo, one on Lake Valencia, and another on the Orinoco, Apure and Portuguesa rivers, starting from Ciudad Bolivar.
In 1901 there was one saladero, or meatpacking establishment, in the Orinoco-Apure region, but it did not.
Among these the Apure, Arauca, Meta and Guaviare hold the first rank.
The Apure is formed by two great rivers, the Uribante and Sarare.
From the Uribante-Sarare junction to the Orinoco the length of the Apure is 645 m., of which Codazzi makes the doubtful claim that 564 are navigable, for there are some troublesome rapids 114 m.
Above its mouth, where the Apure is 3 m.
A few large streams enter the lower Apure from the south, but they are frequently entangled in lateral canals, due to the slight elevation of the plains above sea-level, the waters of the Apure, especially during flood time, having opened a great number of canos before reaching the Orinoco.
The "Oriental" Andes of Colombia give birth to another great affluent of the Orinoco, the Arauca, which soon reaches the plain and parallels the Apure on the south.
Perez says that the Sarare branch of the Apure has formed a gigantic dam across its own course by prodigious quantities of trees, brush, vines and roots, and thus, impounding its own waters, has cut a new channel to the southward across the lowlands and joined the Arauca, from which the Sarare may be reached in small craft and ascended to the vicinity of Pamplona.
Wide, but as it flows northwards it increases its width until, at the point where it receives its Apure affluent, it is over 2 m.
Maintaining its eastern course from the Apure, the main stream finds its way along the southern side of the delta, where it is called the Corosimi river, and enters the sea at the Boca Grande; but in front of the Tortola island, at the beginning of the Corosimi and too m.
It is a stoppingpoint for the incipient steamer traffic of the valley, which is principally confined to the Apure and lower Orinoco.
