Though the celebrity of the riches of Spanish Guiana is chiefly assignable to the geographical situation of the country and the errors of the old maps, we are not justified in denying the existence of any auriferous land in the tract of country of eighty-two thousand square leagues, which stretches between the Orinoco and the Amazon, on the east of the Andes of Quito and New Granada. What I saw of this country between the second and eighth degrees of latitude, and the sixty-sixth and seventy-first degrees of longitude, is entirely composed of granite, and of a gneiss passing into micaceous and talcous slate. These rocks appear naked in the lofty mountains of Parima, as well as in the plains of the Atabapo and the Cassiquiare. Granite predominates there over the other rocks; and though, in both continents, the granite of ancient formation is pretty generally destitute of gold-ore, we cannot thence conclude that the granite of Parima contains no vein, no stratum of auriferous quartz. On the east of the Cassiquiare towards the sources of the Orinoco, we observed that the number of these strata and these veins increased. The granite of these countries, by its structure, its mixture of hornblende, and other geological features alike important, appears to me to belong to a more recent formation, perhaps posterior to the gneiss, and analogous to the stanniferous granites, the hyalomictes, and the pegmatites. Now the least ancient granites are also the least destitute of metals; and several auriferous rivers and torrents in the Andes, in the Salzburg, Fichtelgebirge, and the table-land of the two Castiles, lead us to believe that these granites sometimes contain native gold, and portions of auriferous pyrites and galena disseminated throughout the whole rock, as is the case with tin and magnetic and micaceous iron. The group of the mountains of Parima, several summits of which attain the height of one thousand three hundred toises, was almost entirely unknown before our visit to the Orinoco. This group, however, is a hundred leagues long and eighty broad; and though wherever M. Bonpland and I traversed this vast group of mountains, its structure seemed to us extremely uniform, it would be wrong to affirm that it may not contain very metalliferous transition rocks and mica-slates superimposed on the granite.

I have already observed that the silvery lustre and frequency of mica have contributed to give Guiana great celebrity for metallic wealth. The peak of Calitamini, glowing every evening at sunset with a reddish fire, still attracts the attention of the inhabitants of Maypures. According to the fabulous stories of the natives, the islets of mica-slate, situate in lake Amucu, augment by their reflection the lustre of the nebulae of the southern sky. "Every mountain," says Raleigh, "every stone in the forests of the Orinoco, shines like the precious metals; if it be not gold, it is madre del oro (mother of gold)." Raleigh asserts that he brought back gangues of auriferous white quartz ("harde white sparr"); and to prove the richness of this ore he gives an account of the assays that were made by the officers of the mint at London.* (* Messrs. Westewood, Dimocke, and Bulmar.) I have no reason to believe that the chemists of that time sought to lead Queen Elizabeth into error, and I will not insult the memory of Raleigh by supposing, like his contemporaries,* that the auriferous quartz which he brought home had not been collected in America. (* See the defence of Raleigh in the preface to the Discovery of Guiana, 1596 pages 2 to 4.) We cannot judge of things from which we are separated by so long an interval of time. The gneiss of the littoral chain* contains traces of the precious metals (* In the southern branch of this chain which passes by Yusma, Villa de Cura and Ocumare, particularly near Buria, Los Teques and Los Marietas.); and some grains of gold have been found in the mountains of Parima, near the mission of Encaramada. How can we infer the absolute sterility of the primitive rocks of Guiana from testimony merely negative, from the circumstance that during a journey of three months we saw no auriferous vein appearing above the soil?

In order to bring together whatever may enlighten the government of this country on a subject so long disputed, I will enter upon a few more geological considerations. The mountains of Brazil, notwithstanding the numerous traces of embedded ore which they display between Saint Paul and Villa Rica, have furnished only stream-works of gold. More than six-sevenths of the seventy-eight thousand marks (52,000 pounds) of this metal, with which at the beginning of the 19th century America annually supplied the commerce of Europe, have come, not from the lofty Cordilleras of the Andes, but from the alluvial lands on the east and west of the Cordilleras. These lands are raised but little above the level of the sea, like those of Sonora in Mexico, and of Choco and Barbacoas in New Granada; or they stretch along in table-lands, as in the interior of Brazil.* (* The height of Villa Rica is six hundred and thirty toises; but the great table-land of the Capitania de Minas Geraes is only three hundred toises in height. See the profile which Colonel d'Eschwege has published at Weimar, with an indication of the rocks, in imitation of my profile of the Mexican table-land.) Is it not probable that some other depositions of auriferous earth extend toward the northern hemisphere, as far as the banks of the Upper Orinoco and the Rio Negro, two rivers which form but one basin with that of the Amazon? I observed, when speaking of El Dorado de Canelas, the Omaguas and the Iquiare, that almost all the rivers which flow from the west wash down gold in abundance, and very far from the Cordilleras. From Loxa to Popayan these Cordilleras are composed alternately of trachytes and primitive rocks. The plains of Ramora, of Logrono, and of Macas (Sevilla del Oro), the great Rio Napo with its tributary streams* (the Ansupi and the Coca, in the province of Quixos (* The little rivers Cosanga, Quixos, and Papallacta or Maspa, which form the Coca, rise on the eastern slope of the Nevado de Antisana. The Rio Ansupi brings down the largest grains of gold: it flows into the Napo, south of the Archidona, above the mouth of the Misagualli. Between the Misagualli and the Rio Coca, in the province of Avila, five other northern tributary streams of the Napo (the Siguna, Munino, Suno, Guataracu, and Pucono) are known as being singularly auriferous. These local details are taken from several manuscript reports of the Governor of Quixos, from which I traced the map of the countries east of the Antisana.)), the Caqueta de Mocoa as far as the mouth of the Fragua, in fine, all the country comprised between Jaen de Bracamoros and the Guaviare,* (* From Rio Santiago, a tributary stream of the Upper Maranon, to the Llanos of Caguan and of San Juan.) preserve their ancient celebrity for metallic wealth. More to the east, between the sources of the Guainia (Rio Negro), the Uaupes, the Iquiare, and the Yurubesh, we find a soil incontestably auriferous. There Acunha and Father Fritz placed their Laguna del Oro; and various accounts which I obtained at San Carlos from Portuguese Americans explain perfectly what La Condamine has related of the plates of beaten gold found in the hands of the natives. If we pass from the Iquiare to the left bank of the Rio Negro, we enter a country entirely unknown, between the Rio Branco, the sources of the Essequibo, and the mountains of Portuguese Guiana. Acunha speaks of the gold washed down by the northern tributary streams of the Lower Maranon, such as the Rio Trombetas (Oriximina), the Curupatuba, and the Ginipape (Rio de Paru). It appears to me a circumstance worthy of attention that all these rivers descend from the same table-land, the northern slope of which contains the lake Amucu, the Dorado of Raleigh and the Dutch, and the isthmus between the Rupunuri (Rupunuwini) and the Rio Mahu. There is no reason for denying the existence of auriferous alluvial lands far from the Cordilleras of the Andes on the north of the Amazon; as there are on the south in the mountains of Brazil. The Caribs of the Carony, the Cuyuni and the Essequibo, have practised on a small scale the washing of alluvial earth from the remotest times.* (* "On the north of the confluence of the Curupatuba and the Amazon," says Acunha, "is the mountain of Paraguaxo, which, when illumined by the sun, glows with the most beautiful colours; and thence from time to time issues a horrible noise (revienta con grandes struenos)." Is there a volcanic phenomenon in this eastern part of the New Continent? or is it the love of the marvellous, which has given rise to the tradition of the bellowings (bramidos) of Paraguaxo? The lustre emitted from the sides of the mountain recalls to mind what we have mentioned above of the miraculous rocks of Calitamini, and the island Ipomucena, in the imaginary Lake Dorado. In one of the Spanish letters intercepted at sea by Captain George Popham, in 1594, it is said, "Having inquired of the natives whence they obtained the spangles and powder of gold, which we found in their huts, and which they stick on their skin by means of some greasy substances, they told us that in a certain plain they tore up the grass, and gathered the earth in baskets, to subject it to the process of washing." Raleigh page 109. Can this passage be explained by supposing that the Indians sought thus laboriously, not for gold, but for spangles of mica, which the natives of Rio Caura still employ as ornaments, when they paint their bodies?) When we examine the structure of mountains and embrace in one point of view an extensive surface of the globe, distances disappear; and places the most remote insensibly draw near each other. The basin of the Upper Orinoco, the Rio Negro, and the Amazon is bounded by the mountains of Parime on the north, and by those of Minas Geraes, and Matogrosso on the south. The opposite slopes of the same valley often display an analogy in their geological relations.

I have described in this and the preceding volume the vast provinces of Venezuela and Spanish Guiana. While examining their natural limits, their climate, and their productions, I have discussed the influence produced by the configuration of the soil on agriculture, commerce, and the more or less rapid progress of society. I have successively passed over the three regions that succeed each other from north to south; from the Mediterranean of the West Indies to the forests of the Upper Orinoco and of the Amazon. The fertile land of the shore, the centre of agricultural riches, is succeeded by the Llanos, inhabited by pastoral tribes. These Llanos are in their turn bordered by the region of forests, the inhabitants of which enjoy, I will not say liberty, which is always the result of civilization, but a sort of savage independence. On the limit of these two latter zones the struggle now exists which will decide the emancipation and future prosperity of America. The changes which are preparing cannot efface the individual character of each region; but the manners and condition of the inhabitants will assume a more uniform colour. This consideration perhaps adds interest to a tour made in the beginning of the nineteenth century. We like to see, traced in the same picture, the civilized nations of the sea-shore, and the feeble remains of the natives of the Orinoco, who know no other worship than that of the powers of nature; and who, like the ancient Germans, deify the mysterious object which excites their simple admiration.* (* Deorum nominibus appellant secretum illud, quod sola reverentia vident. Tacitus Germania 9.)

CHAPTER 3.26.

THE LLANOS DEL PAO, OR EASTERN PART OF THE PLAINS OF VENEZUELA. MISSIONS OF THE CARIBS. LAST VISIT TO THE COAST OF NUEVA BARCELONA, CUMANA, AND ARAYA.

Night had set in when we crossed for the last time the bed of the Orinoco. We purposed to rest near the little fort San Rafael, and on the following morning at daybreak to set out on our journey through the plains of Venezuela. Nearly six weeks had elapsed since our arrival at Angostura; and we earnestly wished to reach the coast, with the view of finding, at Cumana, or at Nueva Barcelona, a vessel in which we might embark for the island of Cuba, thence to proceed to Mexico. After the sufferings to which we had been exposed during several months, whilst sailing in small boats on rivers infested by mosquitos, the idea of a sea voyage was not without its charms. We had no idea of ever again returning to South America. Sacrificing the Andes of Peru to the Archipelago of the Philippines (of which so little is known), we adhered to our old plan of remaining a year in New Spain, then proceeding in a galleon from Acapulco to Manila, and returning to Europe by way of Bassora and Aleppo. We imagined that, when we had once left the Spanish possessions in America, the fall of that ministry which had procured for us so many advantages, could not be prejudicial to the execution of our enterprise.

Our mules were in waiting for us on the left bank of the Orinoco. The collection of plants, and the different geological series which we had brought from the Esmeralda and Rio Negro, had greatly augmented our baggage; and, as it would have been dangerous to lose sight of our herbals, we expected to make a very slow journey across the Llanos. The heat was excessive, owing to the reverberation of the soil, which was almost everywhere destitute of vegetation; yet the centigrade thermometer during the day (in the shade) was only from thirty to thirty-four degrees, and during the night, from twenty-seven to twenty-eight degrees. Here, therefore, as almost everywhere within the tropics, it was less the absolute degree of heat than its duration that affected our sensations. We spent thirteen days in crossing the plains, resting a little in the Caribbee (Caraibes) missions and in the little town of Pao. The eastern part of the Llanos through which we passed, between Angostura and Nueva Barcelona, presents the same wild aspect as the western part, through which we had passed from the valleys of Aragua to San Fernando de Apure. In the season of drought, (which is here called summer,) though the sun is in the southern hemisphere, the breeze is felt with greater force in the Llanos of Cumana, than in those of Caracas; because those vast plains, like the cultivated fields of Lombardy, form an inland basin, open to the east, and closed on the north, south and west by high chains of primitive mountains. Unfortunately, we could not avail ourselves of this refreshing breeze, of which the Llaneros, or the inhabitants of the plains, speak with rapture. It was now the rainy season north of the equator; and though it did not rain in the plains, the change in the declination of the sun had for some time caused the action of the polar currents to cease. In the equatorial regions, where the traveller may direct his course by observing the direction of the clouds, and where the oscillations of the mercury in the barometer indicate the hour almost as well as a clock, everything is subject to a regular and uniform rule. The cessation of the breezes, the setting-in of the rainy season, and the frequency of electric explosions, are phenomena which are found to be connected together by immutable laws.

On entering the Llanos of Nueva Barcelona, we met with a Frenchman, at whose house we passed the first night, and who received us with the kindest hospitality. He was a native of Lyons, and he had left his country at a very early age. He appeared extremely indifferent to all that was passing beyond the Atlantic, or, as they say here, disdainfully enough, when speaking of Europe, on the other side of the great pool (al otro lado del charco). Our host was employed in joining large pieces of wood by means of a kind of glue called guayca. This substance, which is used by the carpenters of Angostura, resembles the best animal glue. It is found perfectly prepared between the bark and the alburnum of a creeper* of the family of the Combretaceae. (* Combretum guayca.) It probably resembles in its chemical properties birdlime, the vegetable principle obtained from the berries of the mistletoe, and the internal bark of the holly. An astonishing abundance of this glutinous matter issues from the twining branches of the vejuco de guayca when they are cut. Thus we find within the tropics a substance in a state of purity and deposited in peculiar organs, which in the temperate zone can be procured only by artificial means.

We did not arrive until the third day at the Caribbee missions of Cari. We observed that the ground was less cracked by the drought in this country than in the Llanos of Calabozo. Some showers had revived the vegetation. Small gramina and especially those herbaceous sensitive-plants so useful in fattening half-wild cattle, formed a thick turf. At great distances one from another, there arose a few fan-palms (Corypha tectorum), rhopalas* (chaparro (* The Proteaceae are not, like the Araucaria, an exclusively southern form. We found the Rhopala complicata and the R. obovata, in 2 degrees 30 minutes, and in 10 degrees of north latitude.)), and malpighias* with coriaceous and glossy leaves. (* A neighbouring genus, Byrsonima cocollobaefolia, B. laurifolia, near Matagorda, and B. ropalaefolia.) The humid spots are recognized at a distance by groups of mauritia, which are the sago-trees of those countries. Near the coast this palm-tree constitutes the whole wealth of the Guaraon Indians; and it is somewhat remarkable that we also found it one hundred and sixty leagues farther south, in the midst of the forests of the Upper Orinoco, in the savannahs that surround the granitic peak of Duida.* (* The moriche, like the Sagus Rumphii, is a palm-tree of the marshes, not a palm-tree of the coast, like the Chamaerops humilis, the common cocoa-tree, and the lodoicea.) It was loaded at this season with enormous clusters of red fruit, resembling fir-cones. Our monkeys were extremely fond of this fruit, which has the taste of an over-ripe apple. The monkeys were placed with our baggage on the backs of the mules, and they made great efforts to reach the clusters that hung over their heads. The plain was undulating from the effects of the mirage; and when, after travelling for an hour, we reached the trunks of the palm-trees, which appeared like masts in the horizon, we observed with astonishment how many things are connected with the existence of a single plant. The winds, losing their velocity when in contact with the foliage and the branches, accumulate sand around the trunk. The smell of the fruit and the brightness of the verdure attract from afar the birds of passage, which love to perch on the slender, arrow-like branches of the palm-tree. A soft murmuring is heard around; and overpowered by the heat, and accustomed to the melancholy silence of the plains, the traveller imagines he enjoys some degree of coolness on hearing the slightest sound of the foliage. If we examine the soil on the side opposite to the wind, we find it remains humid long after the rainy season. Insects and worms, everywhere else so rare in the Llanos, here assemble and multiply. This one solitary and often stunted tree, which would not claim the notice of the traveller amid the forests of the Orinoco, spreads life around it in the desert.
