The most remarkable natural curiosity in Maynas is the Pongo or straight, through which the Lauricocha passes the Andes. The river above the Pongo, runs down a mountain channel, forming rapids, cataracts, &c., approaching the eastern ridge of the Andes, where it suddenly contracts its bounds, from 1600 to 600 feet, and rushes through a crevice of tremendous height for the space of eight miles.

The vortices are so powerful here, that a missionary was kept in one for two days, and would have perished with his raft, if the river had not suddenly swollen and carried him out of it. Balsas are always used in this strait, as the spring they have resists the shocks which they experience when dashed against the rocks; in such cases, a canoe or boat would be broke to pieces.

La Condamine was carried through on his balsa at the rate of nine miles an hour, and emerging from the jaws of the mountain, he found himself in a new world, separated from all human intercourse, on a fresh water sea, surrounded by a maze of rivers and lakes, which struck in every direction into the gloom of an immense forest, impenetrable but for them. New plants and animals were exhibited to his view, the soil covered with a dense mass of vegetation never appeared, and nothing was to be seen but verdure and water. Below Borja, and four or 500 hundred leagues beyond it a stone or a pebble is as rare as a diamond.

In Maynas the Indians are great adepts in fishing, and the rivers swarm with tortoises on their shores and islands, which they catch in great numbers. The manati or sea-cow is also sought after by them for food; it is about three or four yards long, and very broad, with two large wing fins. This animal feeds on the herbage growing along shore, and has obtained its name from its great size, and from its suckling its young in the manner of a cow, and its flesh tastes also like beef.

This country, particularly along the rivers, is infested with large snakes, or boa constrictors, and in the places where these abound, the air is generally hot and unhealthy, as is the case along the whole range of the vast river Maranon, which likewise swarms with alligators, venomous reptiles, and insects.

THE GOVERNMENT OF QUIXOS.

The government of Quixos and Macas is the last and most easterly of those of the audience of Quito and kingdom of New Granada; it is bounded on the north by Popayan and the plains; east by Portuguese Guiana; on the west it is separated from Latacunga and Ibarra by the Cordilleras of Cotopaxi, Cayambe, &c., and on the south, it is limited by Maynas and Bracamoros.

This country was first discovered by Gonzalo de Pineda, as before related, in 1536. The viceroy Canete, commissioned Davalos to govern the province, reduce the Indians, and found towns. He accordingly erected Baeza the capital, in 1559, and this was soon followed by the building of Archidona, Avila, and other places.

In Quixos the climate is very hot and moist, the rains being almost continual. It is covered with thick forests, some of the trees in which are of prodigious magnitude. In the south-west of Quixos, is the country called Los Canelos, a sort of spice resembling cinnamon growing there. The south part of Quixos is called Macas, and is separated into a distinct district, under that appellation, of which the chief town is the city of Macas, or Sevilla de Oro.

The climate of Macas is better than that of Quixos, as the proximity of the Andes occasions to be much cooler. The winter here begins in April, and lasts till September, the summer then commences, and the north winds blowing constantly, renders it very mild. The chief occupation of the settlers is the cultivation of tobacco which is exported to Peru; sugar canes thrive very well, as do cotton, grain, &c. Among the infinite variety of trees, which the forests are composed of, is the storax, distinguished by the exquisite fragrancy of its gum. Great quantities of copal are brought from Macas as well as wild wax, and the district contains eight principal villages, and numerous missionary settlements, two priests or superiors governing the spiritual affairs. At the conquest, this country was very populous, owing to the quantity of gold drawn from the neighbourhood of Macas.
