On the solution of this problem depends, in the West India Islands only, and exclusive of the republic of Hayti, the security of 875,000 free men (whites and men of colour* (* Namely: 452,000 whites, of which 342,000 are in the two Spanish Islands (Cuba and Porto Rico), and 423,000 free men of colour, mulattoes, and blacks.)) and the mitigation of the sufferings of 1,150,000 slaves. It is evident that these objects can never be attained by peaceful means, without the concurrence of the local authorities, either colonial assemblies, or meetings of proprietors designated by less dreaded names, by the old parent state. The direct influence of the authorities is indispensable; and it is a fatal error to believe that we may leave it to time to act. Time will act simultaneously on the slaves, on the relations between the islands and the inhabitants of the continent, and on events which cannot be controlled, when they have been waited for with the inaction of apathy. Wherever slavery is long established, the increase of civilization solely has less influence on the treatment of slaves than many are disposed to admit. The civilization of a nation seldom extends to a great number of individuals; and does not reach those who in the plantations are in immediate contact with the blacks. I have known very humane proprietors shrink from the difficulties that arise in the great plantations; they hesitate to disturb established order, to make innovations, which, if not simultaneous, not supported by the legislation, or (which would be more powerful) by public feeling, would fail in their end, and perhaps aggravate the wretchedness of those whose sufferings they were meant to alleviate. These considerations retard the good that might be effected by men animated by the most benevolent intentions, and who deplore the barbarous institutions which have devolved to them by inheritance. They well know that to produce an essential change in the state of the slaves, to lead them progressively to the enjoyment of liberty, requires a firm will on the part of the local authorities, the concurrence of wealthy and enlightened citizens, and a general plan in which all chances of disorder and means of repression are wisely calculated. Without this community of action and effort slavery, with its miseries and excesses, will survive as it did in ancient Rome,* along with elegance of manners, progressive intelligence, and all the charms of the civilization which its presence accuses, and which it threatens to destroy, whenever the hour of vengeance shall arrive. (* The argument deduced from the civilization of Rome and Greece in favour of slavery is much in vogue in the West Indies, where sometimes we find it adorned with all the graces of erudition. Thus, in speeches delivered in 1795, in the Legislative Assembly of Jamaica, it was alleged that from the example of elephants having been employed in the wars of Pyrrhus and Hannibal, it could not be blamable to have brought a hundred dogs and forty hunters from the island of Cuba to hunt the maroon negroes. Bryan Edwards volume 1 page 570.) Civilization, or slow national demoralization, merely prepare the way for future events; but to produce great changes in the social state there must be a coincidence of certain events, the period of the occurrence of which cannot be calculated. Such is the complication of human destiny, that the same cruelties which tarnished the conquest of America have been re-enacted before our own eyes in times which we suppose to be characterized by vast progress, information and general refinement of manners. Within the interval embraced by the span of one life we have seen the reign of terror in France, the expedition to St. Domingo,* (* The North American Review for 1821 Number 30 contains the following passage: Conflicts with slaves fighting for their freedom are not only dreadful on account of the atrocities to which they give rise on both sides; but even after freedom has been gained they help to confound every sentiment of justice and injustice. Some planters are condemning to death all the male negro population above six years of age. They affirm that those who have not borne arms will be contaminated by the example of those who have been fighting. This merciless act is the consequence of the result of the continued misfortunes of the colonies. Charault, Reflexions sur Saint Domingue.), the political re-action in Naples and Spain, I may also add, the massacres of Chio, Ipsara and Missolonghi, the work of the barbarians of Eastern Europe, which the civilized nations of the north and west did not deem it their duty to prevent. In slave countries, where the effect of long habit tends to legitimize institutions the most adverse to justice, it is vain to count on the influence of information, of intellectual culture, or refinement of manners, except in as much as all those benefits accelerate the impulse given by governments and facilitate the execution of measures once adopted. Without the directive action of governments and legislatures a peaceful revolution is a thing not to be hoped for. The danger becomes the more imminent when a general inquietude pervades the public mind; when amidst the political dissensions of neighbouring countries the faults and the duties of governments have been revealed: in such cases tranquillity can be restored only by a ruling authority which, in the noble consciousness of its power and right, sways events by entering itself on the career of improvement.
CHAPTER 3.32.
GEOGNOSTIC DESCRIPTION OF SOUTH AMERICA, NORTH OF THE RIVER AMAZON, AND EAST OF THE MERIDIAN OF THE SIERRA NEVADA DE MERIDA.
The object of this memoir is to concentrate the geological observations which I collected during my journeys among the mountains of New Andalusia and Venezuela, on the banks of the Orinoco and in the Llanos of Barcelona, Calabozo and the Apure; consequently, from the coast of the Caribbean Sea to the valley of the Amazon, between 2 and 10 1/2 degrees north latitude.
The extent of country which I traversed in different directions was more than 15,400 square leagues. It has already formed the subject of a geological sketch, traced hastily on the spot, after my return from the Orinoco, and published in 1801. At that period the direction of the Cordillera on the coast of Venezuela and the existence of the Cordillera of Parime were unknown in Europe. No measure of altitude had been attempted beyond the province of Quito; no rock of South America had been named; there existed no description of the superposition of rocks in any region of the tropics. Under these circumstances an essay tending to prove the identity of the formations of the two hemispheres could not fail to excite interest. The study of the collections which I brought back with me, and four years of journeying in the Andes, have enabled me to rectify my first views, and to extend an investigation which, by reason of its novelty, had been favourably received. That the most remarkable geological relations may be the more easily seized, I shall treat aphoristically, in different sections, the configuration of the soil, the general division of the land, the direction and inclination of the beds and the nature of the primitive, intermediary, secondary and tertiary rocks.
SECTION 1.
Configuration of the Country.
Inequalities of the Soil.
Chains and Groups of Mountains.
Divisionary Ridges.
Plains or Llanos.
South America is one of those great triangular masses which form the three continental parts of the southern hemisphere of the globe. In its exterior configuration it resembles Africa more than Australia. The southern extremities of the three continents are so placed that, in sailing from the Cape of Good Hope (latitude 33 degrees 55 minutes) to Cape Horn (latitude 55 degrees 58 minutes), and doubling the southern point of Van Diemen's Land (latitude 43 degrees 38 minutes), we see those lands stretching out towards the south pole in proportion as we advance eastward. A fourth part of the 571,000 square sea leagues* (* Almost double the extent of Europe.) which South America comprises is covered with mountains distributed in chains or gathered together in groups. The other parts are plains forming long uninterrupted bands covered with forests or gramina, flatter than in Europe, and rising progressively, at the distance of 300 leagues from the coast, between 30 and 170 toises above the level of the sea. The most considerable mountainous chain in South America extends from south to north according to the greatest dimension of the continent; it is not central like the European chains, nor far removed from the sea-shore, like the Himalaya and the Hindoo-Koosh; but it is thrown towards the western extremity of the continent, almost on the coast of the Pacific Ocean. Referring to the profile which I have given* of the configuration of South America (* Map of Columbia according to the astronomical observations of Humboldt by A.H. Brue 1823.), in the latitude of Chimborazo and Grand Para, across the plains of the Amazon, we find the land low towards the east, in an inclined plane, at an angle of less than 25 seconds on a length of 600 leagues; and if, in the ancient state of our planet, the Atlantic Ocean, by some extraordinary cause, ever rose to 1100 feet above its present level (a height one-third less than the table-lands of Spain and Bavaria), the waves must, in the province of Jaen de Bracamoros, have broken upon the rocks that bound the eastern declivity of the Cordilleras of the Andes. The rising of this ridge is so inconsiderable compared to the whole continent that its breadth in the parallel of Cape Saint Roche is 1400 times greater than the average height of the Andes.
We distinguish in the mountainous part of South America a chain and three groups of mountains, namely, the Cordillera of the Andes, which the geologist may trace without interruption from Cape Pilares, in the western part of the Straits of Magellan, to the promontory of Paria opposite the island of Trinidad; the insulated group of the Sierra Nevada de Santa Marta; the group of the mountains of the Orinoco, or of La Parime; and that of the mountains of Brazil. The Sierra de Santa Marta being nearly in the meridian of the Cordilleras of Peru and New Grenada, the snowy summits descried by navigators in passing the mouth of the Rio Magdalena are commonly mistaken for the northern extremity of the Andes. I shall soon prove that the colossal group of the Sierra de Santa Marta is almost entirely separate from the mountains of Ocana and Pamplona which belong to the eastern Cordillera of New Grenada. The hot plains through which runs the Rio Cesar, and which extend towards the valley of Upar, separate the Sierra Nevada from the Paramo de Cacota, south of Pamplona. The ridge which divides the waters between the gulf of Maracaibo and the Rio Magdalena is in the plain on the east of the Laguna Zapatoza. If, on the one hand, the Sierra de Santa Marta has been erroneously considered (on account of its eternal snow, and its longitude) to be a continuation of the Cordillera of the Andes, on the other hand, the connexion of that same Cordillera with the coast mountains of the provinces of Cumana and Caracas has not been recognized. The littoral chain of Venezuela, of which the different ranges form the Montana de Paria, the isthmus of Araya, the Silla of Caracas and the gneiss-granite mountains north and south of the lake of Valencia, is joined between Porto Cabello, San Felipe and Tocuyo to the Paramos de las Rosas and Niquitao, which form the north-east extremity of the Sierra de Merida, and the eastern Cordillera of the Andes of New Grenada. It is sufficient here to mention this connexion, so important in a geological point of view; for the denominations of Andes and Cordilleras being altogether in disuse as applied to the chains of mountains extending from the eastern gulf of Maracaibo to the promontory of Paria, we shall continue to designate those chains (stretching from west to east) by the names of littoral chain, or coast-chain of Venezuela.
Of the three insulated groups of mountains, that is to say, those which are not branches of the Cordillera of the Andes and its continuation towards the shore of Venezuela, one is on the north, and the other two on the west of the Andes: that on the north is the Sierra Nevada de Santa Marta; the two others are the Sierra de la Parime, between 4 and 8 degrees of north latitude, and the mountains of Brazil, between 15 and 28 degrees south latitude. This singular distribution of great inequalities of soil produces three plains or basins, comprising a surface of 420,600 square leagues, or four-fifths of all South America, east of the Andes. Between the coast-chain of Venezuela and the group of the Parime, the plains of the Apure and the Lower Orinoco extend; between the group of Parime and the Brazil mountains are the plains of the Amazon, of the Rio Negro and the Madeira, and between the groups of Brazil and the southern extremity of the continent are the plains of Rio de la Plata and of Patagonia. As the group of the Parime in Spanish Guiana, and of the Brazil mountains (or of Minas Geraes and Goyaz), do not join the Cordillera of the Andes of New Grenada and Upper Peru towards the west, the three plains of the Lower Orinoco, the Amazon, and the Rio de la Plata, are connected by land-straits of considerable breadth. These straits are also plains stretching from north to south, and traversed by ridges imperceptible to the eye but forming divortia aquarum. These ridges (and this remarkable phenomenon has hitherto escaped the attention of geologists) are situated between 2 and 3 degrees north latitude, and 16 and 18 degrees south latitude. The first ridge forms the partition of the waters which fall into the Lower Orinoco on the north-east, and into the Rio Negro and the Amazon on the south and south-east; the second ridge divides the tributary streams of the right bank of the Amazon and the Rio de la Plata. These ridges, of which the existence is only manifested, as in Volhynia, by the course of the waters, are parallel with the coast-chain of Venezuela; they present, as it were, two systems of counter-slopes partially developed, in the direction from west to east, between the Guaviare and the Caqueta, and between the Mamori and the Pilcomayo. It is also worthy of remark that in the southern hemisphere the Cordillera of the Andes sends an immense counterpoise eastward in the promontory of the Sierra Nevada de Cochabamba, whence begins the ridge stretching between the tributary streams of the Madeira and the Paraguay to the lofty group of the mountains of Brazil or Minas Geraes. Three transversal chains (the coast-mountains of Venezuela, of the Orinoco or Parime, and the Brazil mountains) tend to join the longitudinal chain (the Andes) either by an intermediary group (between the lake of Valencia and Tocuyo), or by ridges formed by the intersection of counter-slopes in the plains. The two extremities of the three Llanos which communicate by land-straits, the Llanos of the Lower Orinoco, the Amazon, and the Rio de la Plata or of Buenos Ayres, are steppes covered with gramina, while the intermediary Llano (that of the Amazon) is a thick forest. With respect to the two land-straits forming bands directed from north to south (from the Apure to Caqueta across the Provincia de los Llanos, and the sources of the Mamori to Rio Pilcomayo, across the province of Mocos and Chiquitos) they are bare and grassy steppes like the plains of Caracas and Buenos Ayres.
