The Cordillera of the Andes extends through the whole length of this giant peninsula, from the Strait of Magellan to the Isthmus of Panama, a distance of forty-five hundred miles, forming one of the most remarkable physical features of the globe, and presenting the highest mountains on its surface, except those of the snowy Himalayas which separate India from Thibet. The principal range of the Andes runs nearly parallel with the Pacific coast, at an average distance of about one hundred miles from it, and contains several active volcanoes. If we were to believe a late school geography, published in London, Cotopaxi, one famous peak of this Andean range, throws up flames three thousand feet above the brink of its crater, which is eighteen thousand feet above tide water; but to be on the safe side, let us reduce these extraordinary figures at least one half, as regards the eruptive power of Cotopaxi. This mountain chain, near the border between Chili and Peru, divides into two branches, the principal one still called the Cordillera of the Andes, and the other, nearer to the ocean, the Cordillera de la Costa. Between these ranges, about three thousand feet above the sea, is a vast table-land with an area larger than that of France.

It will be observed that we are dealing with a country which, like our own, is one of magnificent distances. It is difficult for the nations of the old world, where the population is hived together in such circumscribed space, to realize the geographical extent of the American continent. When informed that it required six days and nights, at express speed upon well-equipped railroads, to cross the United States from ocean to ocean, a certain editor in London doubted the statement. Outside of Her Majesty's dominions, the average Englishman has only superficial ideas of geography. The frequent blunders of some British newspapers in these matters are simply ridiculous.

It should be understood that South America is a land of plains as well as of lofty mountains, having the llanos of the Orinoco region, the selvas of the Amazon, and the pampas of the Argentine Republic. The llanos are composed of a region about as large as the New England States, so level that the motion of the rivers can hardly be discerned. The selvas are for the most part vast unbroken forests, in which giant trees, thick undergrowth, and entwining creepers combine to form a nearly impenetrable region. The pampas lie between the Andes and the Atlantic Ocean, stretching southward from northern Brazil to southern Patagonia, affording grass sufficient to feed innumerable herds of wild cattle, but at the extreme south the country sinks into half overflowed marshes and lagoons, resembling the glades and savannahs of Florida.

The largest river in the world, namely, the Amazon, rises in the Peruvian Andes, within sixty miles of the Pacific Ocean, and flows thousands of miles in a general east-northeast direction, finally emptying into the Atlantic Ocean. This unequaled river course is navigable for over two thousand miles from its mouth, which is situated on the equatorial line, where its outflow is partially impeded by the island of Marajo, a nearly round formation, one hundred and fifty miles or thereabouts in diameter. This remarkable island divides the river's outlet into two passages, the largest of which is a hundred and fifty miles in width, forming an estuary of extraordinary dimensions. The Amazon has twelve tributaries, each one of which is a thousand miles in length, not to count its hundreds of smaller ones, while the main stream affords water communication from the Atlantic Ocean to near the foothills of the Andes.

We are simply stating a series of condensed geographical facts, from which the intelligent reader can form his own deductions as regards the undeveloped possibilities of this great southland.

Our own mammoth river, the Mississippi, is a comparatively shallow stream, with a shifting channel and dangerous sandbanks, which impede navigation throughout the most of its course; while the Amazon shows an average depth of over one hundred feet for the first thousand miles of its flow from the Atlantic, forming inland seas in many places, so spacious that the opposite banks are not within sight of each other. It is computed by good authority that this river, with its numerous affluents, forms a system of navigable water twenty-four thousand miles in length! There are comparatively few towns or settlements of any importance on the banks of the Amazon, which flows mostly through a dense, unpeopled evergreen forest, not absolutely without human beings, but for very long distances nearly so. Wild animals, anacondas and other reptiles, together with many varieties of birds and numerous tribes of monkeys, make up the animal life. Now and again a settlement of European colonists is found, or a rude Indian village is seen near the banks, but they are few and far between. There are occasional regions of low, marshy ground, which are malarious at certain seasons, but the average country is salubrious, and capable of supporting a population of millions.

This is only one of the large rivers of South America; there are many others of grand proportions. The Plate comes next to it in magnitude, having a length of two thousand miles, and being navigable for one half the distance from its mouth at all seasons. It is over sixty miles wide at Montevideo, and is therefore the widest known river. Like the great stream already described, it traverses a country remarkable for the fertility of its soil, but very thinly settled. The Plate carries to the ocean four fifths as much, in volume of water, as does the mighty Amazon, the watershed drained by it exceeding a million and a half square miles. One can only conceive of the true magnitude of such figures when applied to the land by comparing the number of square miles contained in any one European nation, or any dozen of our own States.

Juan Diaz de Solis discovered the estuary of the Plate in 1508, and believed it at that time to be a gulf, but on a second voyage from Europe, in 1516, he ascended the river a considerable distance, and called it Mar Dulce, on account of the character of the waters. Unfortunately, this intelligent discoverer was killed by Indian arrows on attempting to land at a certain point. For a considerable period the river was called after him, and we think should have continued to be so, but its name was changed to the Plate on account of the conspicuous silver ornaments worn in great profusion by the natives, which they freely exchanged for European gewgaws.

Though nearly four hundred years have passed since its discovery, a large portion of the country still remains comparatively unexplored, much of it being a wilderness sparsely inhabited by Indians, many of whom are without a vestige of civilization. We know as little of portions of the continent as we do of Central Africa, yet there is no section of the globe which suggests a greater degree of physical interest, or which would respond more readily and profitably to intelligent effort at development. When the Spaniards first came to South America, it was only in Peru, the land of the Incas, that they found natives who had made any substantial progress in civilization. The earliest history extant relating to this region of the globe is that of the Incas, a warlike race of sun-worshipers, who possessed enormous treasures of gold and silver, and who erected magnificent temples enriched with the precious metals. It was the almost fabulous wealth of the Incas that led to their destruction, tempting the cupidity of the avaricious Spaniards, and causing them to institute a system of cruelty, oppression, robbery, and bloodshed which finally obliterated an entire people from the face of the globe. The empire of the Incas extended from Quito, in Ecuador (on the equator), to the river Monté in Chili, and eastward to the Andes. The romantic career of Pizarro and Cortez is familiar to us all. There are few palliating circumstances connected with the advent of the Spaniards, either here, in the West Indies, or in Mexico. The actual motive which prompted their invasion of this foreign soil was to search for mineral treasures, though policy led them to cover their bloodthirsty deeds with a pretense of religious zeal. Their first acts were reckless, cruel, and sanguinary, followed by a systematic oppression of the native races which was an outrage upon humanity. The world at large profited little by the extortion and golden harvest reaped by Spain, to realize which she adopted a policy of extermination, both in Peru and in Mexico; but let it be remembered that her own national ruin was brought about with poetical justice by the very excess of her ill-gotten, blood-stained treasures. The Spanish historians tell us, as an evidence of the persistent bravery of their ancestors, that it took them eight hundred years of constant warfare to wrest Spain from her Moorish conquerors. It is for us to remind them how brief has been the continuance of their glory, how rapid their decline from splendid continental and colonial possessions to their present condition, that of the weakest and most insignificant power in Europe.

There are localities which have been visited by adventurous explorers, especially in Chili and Peru, where ruins have been found, and various monuments of antiquity examined, of vast interest to archæologists, but of which scarcely more than their mere existence is recorded. Some of these ruins are believed to antedate by centuries the period of the Incas, and are supposed to be the remains of tribes which, judging from their pottery and other domestic utensils, were possibly of Asiatic origin. Comparatively few travelers have visited Lake Titicaca, in the Peruvian Andes, with its sacred islands and mysterious ruins, from whence the Incas dated their mythical origin. The substantial remains of some grand temples are still to be seen on the islands near the borders of the lake, the decaying masonry decked here and there with a wild growth of hardy cactus. This remarkable body of water, Lake Titicaca, in the mountain range of Peru, lies more than twelve thousand feet above the level of the Pacific; yet it never freezes, and its average depth is given as six hundred feet, representing an immense body of water. It covers an area of four thousand square miles, which is about four fifths as large as our own Lake Ontario, the average depth being about the same. Titicaca is the largest lake in the world occupying so elevated a site.

The population of South America is mostly to be found on the coast, and is thought to be about thirty-five millions, though, all things considered, we are disposed to believe this an overestimate. There are tribes far inland who are not brought in contact with civilization at all, and whose numbers are not known. The magnitude and density of the forests are remarkable; they cover, it is intelligently stated, nearly two thirds of the country. The vegetation, in its various forms, is rich beyond comparison. Professor Agassiz, who explored the valley of the Amazon under the most favorable auspices, tells us that he found within an area of half a mile square over one hundred species of trees, among which were nearly all of the choicest cabinet and dye woods known to the tropics, besides others suitable for shipbuilding. Some of these trees are remarkable for their gigantic size, others for their beauty of form, and still others are valuable for their gums and resins. Of the latter, the india-rubber tree is the most prolific and important known to commerce. From Brazil comes four fifths of the world's supply of the raw material of rubber.

The great fertility of the soil generally would seem to militate against the true progress of the people of South America, absolutely discouraging, rather than stimulating national industry. One cannot but contrast the state of affairs in this respect with that of North America, where the soil is so much less productive, and where the climate is so universally rigorous. The deduction is inevitable that, to find man at his best, we must observe him where his skill, energy, and perseverance are all required to achieve a livelihood, and not where exuberant nature is over-indulgent, over-productive. The coast, the valleys, and indeed the main portion of South America are tropical, but a considerable section of the country is so elevated that its climate is that of perpetual spring, resembling the great Mexican plateau, both physically and as regards temperature. The population is largely of Spanish descent, and that language is almost universally spoken, though Portuguese is the current tongue in Brazil. These languages are so similar, in fact, that the people of the two nations can easily understand each other. It is said to be true that, in the wild regions of the country, there are tribes of Indians found to-day living close to each other, separated by no physical barriers, who differ materially in language, physiognomy, manners, and customs, having absolutely nothing in common but their brown or copper colored skins. Furthermore, these tribes live most frequently in deadly feuds with each other. That cannibalism is still practiced among these interior tribes is positively believed, especially among some of the tribes of the extreme south, that is, among the Patagonians and the wild, nomadic race of Terra del Fuego. These two tribes, on opposite sides of the Strait of Magellan, are quite different from each other in nearly every respect, especially in size, nor will they attempt to hold friendly intercourse of any sort with each other.

There are certain domestic animals which are believed to be improved by crossing them with others of a different type, but this does not seem to apply, very often, advantageously to different races of human beings. It is plain enough in South America that the amalgamation of foreigners and natives rapidly effaces the original better qualities of each, the result being a mongrel, nondescript type, hard to analyze and hard to improve. That keen observer, Professor Agassiz, especially noticed this during his year of scientific research in Brazil. This has also been the author's experience, as illustrated in many lands, where strictly different races, the one highly civilized, the other barbarian, have unitedly produced children. It is a sort of amalgamation which nature does not favor, recording her objections in an unmistakable manner. It is the flow of European emigration towards these southern republics which will infuse new life and progress among them. The aboriginal race is slowly receding, and fading out, as was the case in Australia, in New Zealand, and in the instance of our western Indians. A new people will eventually possess the land, composed of the several European nationalities, who are already the virtual masters of South America so far as regards numbers, intelligence, and possession.

Since these notes were written, the Argentine government has sold to Baron Hirsch three thousand square leagues of land in the province of Chaco, for the formation of a Jewish colony. Agents are already at work, aided by competent engineers and practical individuals, in preparing for the early reception of the new occupants of the country. The first contingent, of about one thousand Jews, have already arrived and are becoming domesticated. Argentina wants men perhaps more than money; indeed, one will make the other. A part of Baron Hirsch's scheme is to lend these people money, to be repaid in small installments extending over a considerable period. For this extensive territory the Baron paid one million three hundred thousand dollars in gold, thus making himself the owner of the largest connected area of land in the world possessed by a single individual. It exceeds that of the kingdom of Montenegro.

As to the zoölogy of this part of the continent, it is different from that of Europe, Africa, Asia, and North America. The number of dangerous beasts of prey is quite limited. There is nothing here to answer to the African lion, the Asiatic tiger, the elephant of Ceylon, or the grisly bear of Alaska. The jaguar is perhaps the most formidable animal, and resembles the leopard. There are also the cougar, tiger-cat, black bear, hyena, wolf, and ocelot. The llama, alpaca, and vicuña are peculiar to this country. The monkey tribe exceeds all others in variety and number. There are said to be nearly two hundred species of them in South America, each distinctly marked, and varying from each other, in size, from twelve pounds to less than two. The smallest of the little marmosets weigh less than a pound and a half each, and are the most intelligent animal of their size known to man. There are also the deer, tapir, armadillo, anteater, and a few other minor animals. The pampas swarm with wild cattle and horses, descended from animals originally brought from Europe. In the low, marshy grounds the boa-constrictor and other reptiles abound. Eagles, vultures, and parrots are found in a wild state all over the country, while the rivers and the waters near the coast are well filled with fish, crocodiles, and turtles. Scientists have found over two thousand species of fish in the Amazon River alone.
