The riches of the few Spaniards and creoles settled in this province, consists in cattle, of which the missionary Franciscans alone possess more than 150,000 head.

The trade of Guiana consists entirely in the export of cattle and mules, with some tobacco, cotton, and indigo, and in 1803 they had thirty-four small vessels employed in trading to Trinidad and the neighbouring Spanish ports.

In the history of the discovery of Guiana much obscurity prevails; but Martin Silva, in 1568, obtained a patent to conquer some tribes to the westward of the present limits. After penetrating through Venezuela, his people deserted him; when he returned to Spain, and collected new followers. Silva then attempted to cross the country from the coast between the Maranon and Orinoco, but he and his followers were slain and devoured by the Caribs. The missionaries, Pizarro's brother, and Diego Ordaz, also attempted to enter and explore Guiana, but were all frustrated by the natives.

Sir Walter Raleigh also twice tried to reach the pretended city of Manoa, or El Dorado, which is supposed to have been situated in lake Parima, and whose streets were paved with gold; which marvellous story had most probably its origin in an Indian village, built on an island whose soil contained mica, which glittering, and appearing splendid in the sunshine, deceived the adventurers who had observed it.

In later times the Spaniards have endeavoured to conquer these regions, but have always been unsuccessful; one of them has had the courage to cross the greater part of the country in the dress of an Indian; and from his researches, the direction of the ranges of mountains has been ascertained. Humboldt, also contrived to go a great distance along the chain of the cataracts, but was prevented from exploring the sources of the Orinoco and the celebrated lake of Parima by the Guayecas, a race of Indians who, though of very diminutive stature, display the utmost courage and activity in defending their possessions. These people resist all persuasion to become the converts of the monks who had visited their frontiers, and equally defy the armed force which generally accompanies these priests.

The rivers flowing through Guiana, which are best known, are the Orinoco, into which, on the north, the Caroni, the Aruy, the Caura, and several smaller ones empty themselves; on the west the Suapure, the Sippapu, &c., join that stream, while on the south the Guaviare, the Ynritta and the Atabapo also add to the magnificence of its course. The Rio Negro also flows through a part of Guiana, and forms, by means of the Cassiquiari, a junction between the Maranon and the Orinoco, thus constituting Guiana an immense island detached in every direction by a broad expanse of water from the continent of South America.

The Yapura and the Uapes run through the southern or continental parts of this province, and join the Maranon.

Many large rivers issue from, or rise near lake Parima and the interior; of which Rio Branco and the Siaba are the most noted, but as the lake itself, and all the surrounding country are as unknown as the internal parts of Africa, it will be useless to repeat names that are gathered from maps, often imaginary, and generally erroneous.

The capital of Guiana is Santo Tomé, or Angostura, (the strait, so called, because situated in a narrow part of the Orinoco;) it was originally built in 1586, nearer the sea, at the distance of fifty leagues from the mouth of the river, but having suffered successively from the invasions of the English, French and Dutch, it was removed, in 1764, to its present scite, ninety leagues from the Atlantic, on the right bank of the river, at the foot of a small mountain. Opposite the city is a village and fortress on the left bank of the Orinoco.

This place was built for the defence of the passage of the Strait, and is called Port Rafael. Between this port and the city is the island Del Medio, a low rocky islet, covered during the floods. The channel lies between this shoal and the town, the river being 200 feet broad at low water. Santo Tomé is the seat of government, the bishop and governor of Guiana residing in it, but its buildings are said to be mean, and its appearance unworthy of a better title than that of a large village.
