Colombia and Ecuador occupy the northwestern part of South America. They are situated on both sides of the Andes, and have every variety of climate. The country is well watered; fertile but unhealthy on the coast, fertile and healthy on the elevated plains, cold and barren on the mountains.
In Brazil, besides the Amazon, La Plata and San Francisco, there are several large rivers with fertile valleys; but occasional droughts, sometimes lasting for two years, will prevent portions of Brazil from becoming densely inhabited.
On the Pacific coast south of Ecuador, the rainfall becomes less and less. For three thousand miles along the coast of Peru and Chili there is no natural harbor; a plain from ten to fifty miles in width extends from the Pacific to the foot-hills of the Andes. The Antarctic current runs along this coast; the southeasterly winds blow over it on to the land and cool the air; but as the winds are of low temperature their scanty vapor is dissipated by the heat radiated from the land, and not a drop of rain refreshes the thirsty soil. Many mountain torrents run from the snow-clad summits of the Andes, and the beauty of their narrow valleys forms a grateful contrast to the dry and barren sands of the plain.
In the southern part of Chili and in that part formerly called Patagonia, rain is abundant and the country is fertile.
The longest stretch of low and comparatively level land to be found in the world extends through the center of South America. A boat starting from the Caribbean sea could sail up the Orinoco over a thousand miles, then down the Casquiare, which runs from the Orinoco into the Rio Negro, down that river to the Amazon, up the Amazon to the Madeira, then up that river and one of its branches through Brazil and Bolivia, and with a short portage of six and a half miles to one of the branches of the Paraguay, down the Paraguay and La Plata to the ocean.
The level land crosses the La Plata and continues southward through the Argentine Republic and Patagonia to the Straits of Magellan. Within this plain lie all the interior of Venezuela and Brazil, a part of Bolivia, all Paraguay, Uruguay, and the Argentine Republic. The pampas resemble our prairies, but run from north to south, while the prairies run from east to west.
The streams in the plain south of the valley of the La Plata rise in the Andes and flow southeastward to the Atlantic.
THE ABORIGINES.
The aborigines of America, except the Esquimaux, are unlike the natives of other countries; the most marked difference is in their language. They are divided into a number of tribes differing from each other in some respects, yet with manners, customs and religious beliefs generally similar.
In South America there are more than one hundred distinct languages, and two thousand dialects. About five or six million Indians have as many dialects as are found among the 800,000,000 inhabitants of Europe and Asia. Their languages are polysynthetic, being of a higher type than the agglutinative languages. In the polysynthetic tongue the substantive, adjective and verb are joined or combined, and oftentimes a whole sentence will be comprised in a single word.
