In the forest region of the Amazon there is much precipitation. The open plains of the Orinoco section have less rain, with a dry season when the rivers, which overflow in the wet season, return to their channels and the vegetation withers. Farther north, the Sierra de Perija of the East Cordillera condenses the moisture of the northeast trade winds, causing heavy rainfall on the eastern slope, but having a dry section on the west. The Caribbean coast near Panamá has plenty of rain, which diminishes towards the north, Goajira being quite arid. Excessive precipitation occurs on the West Cordillera, on the Baudó Range, and on the southern part of the Pacific Coast, where the plains are heavily forested and unhealthful like the valleys of the San Juan and Atrato farther north. The lower valleys of the Magdalena and Cauca, shut off from the prevailing winds, are decidedly hot. These and other lowland plains have the tropical climate, in general great humidity, and many dense forests, except for the open drier llanos.

Above this region are enjoyable climates, the sub-tropical ranging from 1500 to 7500 feet; still higher to 10,000 feet the seasons are agreeably temperate in character. Beyond this altitude it becomes quite cold, with bleak plains and passes, here called paramos, mostly from 12,000 to 15,000 feet above the sea. Higher yet are regions of perpetual snow.

The Santa Marta Plateau, the upper section of the Cauca Valley, the greater part of the country traversed by the East Cordillera, and the northern end of the Central enjoy the subtropical or the temperate climate. Here is a large proportion of the white population, and here the chief industries are located. In the tropical forests and in the lower plains and valleys the annual mean temperature is from 82° to over 90°; at Medellín with an altitude of 5000 feet it is 70°, and at Bogotá, altitude 8600 feet, it is 57°.

In the north there are two seasons a year, a wet and a dry, though not everywhere well defined; nearer the equator there are four, two wet and two drier, as the sun passes overhead twice a year. On the damp paramos the moist wintry seasons are long and cold, so these parts are unfrequented save by shepherds in the warmer periods. It is estimated that a section of 150,000 square miles, twice the size of England, has an elevation of 7000 feet or more, and there are few points on the coast from which an agreeable climate could not be reached in a few hours by automobile or train if roads were provided.

CHAPTER IV
COLOMBIA: THE CAPITAL, THE STATES AND TERRITORIES, CHIEF CITIES

The Capital

Bogotá, the Capital of Colombia, is situated on a plateau or savanna, a sort of shelf over 8000 feet above the sea, on the west side of the East Cordillera. The shelf, overlooked by fine snowclad volcanoes, has a low rim on the west and a high ridge on the east. About 70 miles long and 30 wide, it is entirely covered with towns and farms. The city is the largest in Colombia (population probably 150,000), on account of its being the capital and having a good climate; the mean temperature ranges from 54° to 64°. 600 miles from the north coast and 210 from the Pacific, Bogotá is the most difficult of access of any of the South American capitals. Nevertheless, the city has always been noted as the home of culture and of intellectual tastes. It is well laid out and covers a large area, as the houses are of only one or two stories with interior patios or courts, as in most South American cities. Many streets have asphalt pavements; there are hundreds of carriages and automobiles, also 23 miles of electric tramways. Like all South American cities, it has large plazas, open squares usually with trees and other green in the centre, and public gardens. The Capitol is an imposing building covering two and a half acres. Other good public buildings include the Presidential Palace, a public library, a museum, etc. Of course there is a cathedral and many churches, two theatres of the first rank, several fair hotels, a large bull ring, a hippodrome, polo grounds, etc. Here are telephones and electric lights as in all other considerable cities. The people are industrious, intelligent, and fond of amusement.

A more precise idea of the geography of Colombia and of the commercial possibilities of the different sections will be gained by reviewing them in order, beginning with the north coast, going around the outside, and concluding with the interior.

States and Territories

The Goajira Peninsula, a Comisaría at the northeast, is inhabited chiefly by Indians who are practically independent. They gather forest products such as tagua nuts (vegetable ivory), breed useful horses, and do some trading at the port of Riohacha in Magdalena. A few savage tribes make travel in some sections dangerous. The peninsula contains much wet lowlands, as well as mountains, extensive forests, and fine fertile country, with considerable mineral wealth yet unexploited: gold, and probably extensive veins of coal. Large sections covered with guinea grass are capable of supporting great herds of cattle.
