2. The Guaraons or Gu-ara-una, almost all free and independent, are dispersed in the Delta of the Orinoco, with the variously ramified channels of which they alone are well acquainted. The Caribbees call the Guaraons U-ara-u. They owe their independence to the nature of their country; for the missionaries, in spite of their zeal, have not been tempted to follow them to the tree-tops. The Guaraons, in order to raise their abodes above the surface of the waters at the period of the great inundations, support them on the hewn trunks of the mangrove-tree and of the Mauritia palm-tree.* (* Their manners have been the same from time immemorial. Cardinal Bembo described them at the beginning of the 16th century, "quibusdam in locis propter paludes incolae domus in arboribus aedificant." (Hist. Venet. 1551.) Sir Walter Raleigh, in 1595, speaks of the Guaraons under the names of Araottes, Trivitivas, and Warawites. These were perhaps the names of some tribes, into which the great Guaraonese nation was divided. (Barrere Essai sur l'Hist. Naturelle de la France Equinoctiale.)) They make bread of the medullary flour of this palm-tree, which is the sago of America. The flour bears the name of yuruma: I have eaten it at the town of St. Thomas, in Guiana, and it was very agreeable to the taste, resembling rather the cassava-bread than the sago of India.* (* M. Kunth has combined together three genera of the palms, Calamus, Sigus, and Mauritia, in a new section, the Calameae.) The Indians assured me that the trunks of the Mauritia, the tree of life so much vaunted by father Gumilla, do not yield meal in any abundance, unless the palm-tree is cut down just before the flowers appear. Thus too the maguey,* (* Agave Americana, the aloe of our gardens.) cultivated in New Spain, furnishes a saccharine liquor, the wine (pulque) of the Mexicans, only at the period when the plant shoots forth its long stem. By interrupting the blossoming, nature is obliged to carry elsewhere the saccharine or amylaceous matter, which would accumulate in the flowers of the maguey and in the fruit of the Mauritia. Some families of Guaraons, associated with the Chaymas, live far from their native land, in the Missions of the plains or llanos of Cumana; for instance, at Santa Rosa de Ocopi. Five or six hundred of them voluntarily quitted their marshes, a few years ago, and formed, on the northern and southern banks of the Orinoco, twenty-five leagues distant from Cape Barima, two considerable villages, under the names of Zacupana and Imataca. When I made my journey in Caripe, these Indians were still without missionaries, and lived in complete independence. Their excellent qualities as boatmen, their perfect knowledge of the mouths of the Orinoco, and of the labyrinth of branches communicating with each other, give the Guaraons a certain political importance. They favour that clandestine commerce of which the island of Trinidad is the centre. The Guaraons run with extreme address on muddy lands, where the European, the Negro, or other Indians except themselves, would not dare to walk; and it is, therefore, commonly believed, that they are of lighter weight than the rest of the natives. This is also the opinion that is held in Asia of the Burat Tartars. The few Guaraons whom I saw were of middle size, squat, and very muscular. The lightness with which they walk in places newly dried, without sinking in, when even they have no planks tied to their feet, seemed to me the effect of long habit. Though I sailed a considerable time on the Orinoco, I never went so low as its mouth. Future travellers, who may visit those marshy regions, will rectify what I have advanced.

3. The Guaiqueries or Guaikeri, are the most able and most intrepid fishermen of these countries. These people alone are well acquainted with the bank abounding with fish, which surrounds the islands of Coche, Margareta, Sola, and Testigos; a bank of more than four hundred square leagues, extending east and west from Maniquarez to the Boca del Draco. The Guaiqueries inhabit the island of Margareta, the peninsula of Araya, and that suburb of Cumana which bears their name. Their language is believed to be a dialect of that of the Guaraons. This would connect them with the great family of the Caribbee nations; and the missionary Gili is of opinion that the language of the Guaiqueries is one of the numerous branches of the Caribbean tongue.* (* If the name of the port Pam-patar, in the island of Margareta, be Guaiquerean, as we have no reason to doubt, it exhibits a feature of analogy with the Cumanagoto tongue, which approaches the Caribbean and Tamanac. In Terra Firma, in the Piritu Missions, we find the village of Cayguapatar, which signifies house of Caygua.) These affinities are interesting, because they lead us to perceive an ancient connection between nations dispersed over a vast extent of country, from the mouth of the Rio Caura and the sources of the Erevato, in Parima, to French Guiana, and the coasts of Paria.* (* Are the Guaiqueries, or O-aikeries, now settled on the borders of the Erevato, and formerly between the Rio Caura and the Cuchivero near the little town of Alta Gracia, of a different origin from the Guaikeries of Cumana? I know also, in the interior of the country, in the Missions of the Piritus, near the village of San Juan Evangelista del Guarive, a ravine very anciently called Guayquiricuar. These resemblances seem to prove migrations from the south-west towards the coast. The termination cuar, found so often in Cumanagoto and Caribbean names, means a ravine, as in Guaymacuar (ravine of lizards), Pirichucuar (a ravine overshaded by pirichu or piritu palm-trees), Chiguatacuar (a ravine of land-shells). Raleigh describes the Guaiqueries under the name of Ouikeries. He calls the Chaymas, Saimas, changing (according to the Caribbean pronunciation) the ch into s.)

4. The Quaquas, whom the Tamanacs call Mapoje, are a tribe formerly very warlike and allied to the Caribbees. It is a curious phenomenon to find the Quaquas mingled with the Chaymas in the Missions of Cumana, for their language, as well as the Atura, of the cataracts of the Orinoco, is a dialect of the Salive tongue; and their original abode was on the banks of the Assiveru, which the Spaniards call Cuchivero. They have extended their migrations one hundred leagues to the north-east. I have often heard them mentioned on the Orinoco, above the mouth of the Meta; and, what is very remarkable, it is asserted* that missionary Jesuits have found Quaquas as far distant as the Cordilleras of Popayan. (* Vater tome 3 part 2 page 364. The name of Quaqua is found on the coast of Guinea. The Europeans apply it to a horde of Negroes to the east of Cape Lahou.) Raleigh enumerates, among the natives of the island of Trinidad, the Salives, a people remarkable for their mild manners; they came from the Orinoco, and settled south of the Quaquas. Perhaps these two nations, which speak almost the same language, travelled together towards the coasts.

5. The Cumanagotos, or, according to the pronunciation of the Indians, Cumanacoto, are now settled westward of Cumana, in the Missions of Piritu, where they live by cultivating the ground. They number more than twenty-six thousand. Their language, like that of the Palencas, or Palenques, and Guarivas, is between the Tamanac and the Caribbee, but nearer to the former. These are indeed idioms of the same family; but if we are to consider them as simple dialects, the Latin must be also called a dialect of the Greek, and the Swedish a dialect of the German. In considering the affinity of languages one with another, it must not be forgotten that these affinities may be very differently graduated; and that it would be a source of confusion not to distinguish between simple dialects and languages of the same family. The Cumanagotos, the Tamanacs, the Chaymas, the Guaraons, and the Caribbees, do not understand each other, in spite of the frequent analogy of words and of grammatical structure exhibited in their respective idioms. The Cumanagotos inhabited, at the beginning of the sixteenth century, the mountains of the Brigantine and of Parabolata. I am unable to determine whether the Piritus, Cocheymas, Chacopatas, Tomuzas, and Topocuares, now confounded in the same villages with the Cumanagotos, and speaking their language, were originally tribes of the same nation. The Piritus take their name from the ravine Pirichucuar, where the small thorny palm-tree,* called piritu, grows in abundance (* Caudice gracili aculeato, foliis pinnatis. Possibly of the genus Aiphanes of Willdenouw.); the wood of this tree, which is excessively hard, and little combustible, serves to make pipes. On this spot the village of La Concepcion de Piritu was founded in 1556; it is the chief settlement of the Cumanagoto Missions, known by the name of the Misiones de Piritu.

6. The Caribbees (Carives). This name, which was given them by the first navigators, is retained throughout all Spanish America. The French and the Germans have transformed it, I know not why, into Caraibes. The people call themselves Carina, Calina, and Callinago. I visited some Caribbean Missions in the Llanos,* (* I shall in future use the word Llanos (loca plana, suppressing the p), without adding the equivalent words pampas, savannahs, meadows, steppes, or plains. The country between the mountains of the coast and the left bank of the Orinoco, constitutes the llanos of Cumana, Barcelona, and Caracas.) on returning from my journey to the Orinoco; and I shall merely mention that the Galibes (Caribi of Cayenne), the Tuapocas, and the Cunaguaras, who originally inhabited the plains between the mountains of Caripe (Caribe) and the village of Maturin, the Jaoi of the island of Trinidad and of the province of Cumana, and perhaps also the Guarivas, allies of the Palencas, are all tribes of the great Caribbee nation.

With respect to the other nations whose affinities of language with the Tamanac and Caribbee have been mentioned, they are not necessarily to be considered as of the same race. In Asia, the nations of Mongol origin differ totally in their physical organisation from those of Tartar origin. Such has been, however, the intermixture of these nations, that, according to the able researches of Klaproth, the Tartar languages (branches of the ancient Oigour) are spoken at present by hordes incontestably of Mongol race. Neither the analogy nor the diversity of language suffice to solve the great problem of the filiation of nations; they merely serve to point out probabilities. The Caribbees, properly speaking, those who inhabit the Missions of the Cari, in the llanos of Cumana, the banks of the Caura, and the plains to the north-east of the sources of the Orinoco, are distinguished by their almost gigantic size from all the other nations I have seen in the new continent. Must it on this account be admitted, that the Caribbees are an entirely distinct race? and that the Guaraons and the Tamanacs, whose languages have an affinity with the Caribbee, have no bond of relationship with them? I think not. Among the nations of the same family, one branch may acquire an extraordinary development of organization. The mountaineers of the Tyrol and Salzburgh are taller than the other Germanic races; the Samoiedes of the Altai are not so little and squat as those of the sea-coast. In like manner it would be difficult to deny that the Galibis are really Caribbees; and yet, notwithstanding the identity of languages, how striking is the difference in their stature and physical constitution!

Before Cortez entered the capital of Montezuma in 1521, the attention of Europe was fixed on the regions we have just traversed. In depicting the manners of the inhabitants of Paria and Cumana, it was thought that the manners of all the inhabitants of the new continent were described. This remark cannot escape those who read the historians of the Conquest, especially the letters of Peter Martyr of Anghiera, written at the court of Ferdinand the Catholic. These letters are full of ingenious observations upon Christopher Columbus, Leo X, and Luther, and are stamped by noble enthusiasm for the great discoveries of an age so rich in extraordinary events. Without entering into any detail on the manners of the nations which have been so long confounded one with another, under the vague denomination of Cumanians (Cumaneses), it appears to me important to clear up a fact which I have often heard discussed in Spanish America.

The Pariagotos of the present time are of a brown red colour, as are the Caribbees, the Chaymas, and almost all the nations of the New World. Why do the historians of the sixteenth century affirm that the first navigators saw white men with fair hair at the promontory of Paria? Were they of the same race as those Indians of a less tawny hue, whom M. Bonpland and myself saw at Esmeralda, near the sources of the Orinoco? But these Indians had hair as black as the Otomacs and other tribes, whose complexion is the darkest. Were they albinos, such as have been found heretofore in the isthmus of Panama? But examples of that degeneration are very rare in the copper-coloured race; and Anghiera, as well as Gomara, speaks of the inhabitants of Paria in general, and not of a few individuals. Both describe them as if they were people of Germanic origin,* (* "Aethiopes nigri, crispi lanati; Pariae incolae albi, capillis oblongis protensis flavis."—Pet. Martyr Ocean., dec. 50 lib. 6 (edition 1574). "Utriusque sexus indigenae albi veluti nostrates, praeter eos qui sub sole versantur." (The natives of both sexes are as white as our people [Spaniards], except those who are exposed to the sun.)—Ibid. Gomara, speaking of the natives seen by Columbus at the mouth of the river of Cumana, says: "Las donzellas eran amorosas, desnudas y blancas (las de la casa); los Indios que van al campo estan negros del sol." (The young women are engaging in their manners: they wear no clothing, and those who live in the houses ARE WHITE. The Indians who are much in the open country are black, from the effect of the sun.)—Hist. de los Indios, cap. 74. "Los Indios de Paria son BLANCOS y rubios."—(The Indians of Paria are WHITE and red.) Garcia, Origen de los Indios 1729, lib. 4 cap. 9.) they call them 'Whites with light hair;' they even add, that they wore garments like those of the Turks.* (* "They wear round their head a striped cotton handkerchief"—Ferd. Columb. cap. 71. (Churchill volume 2.) Was this kind of head-dress taken for a turban? (Garcia, Origen de los Ind., page 303). I am surprised that people of these regions should have worn a head-dress; but, what is more curious still, Pinzon, in a voyage which he made alone to the coast of Paria, the particulars of which have been transmitted to us by Peter Martyr of Anghiera, professes to have seen natives who were clothed: "Incolas omnes genu tenus mares, foeminas surarum tenus, gossampinis vestibus amictos simplicibus repererunt; sed viros more Turcorum insuto minutim gossypio ad belli usum duplicibus." (The natives were clothed in thin cotton garments; the men's reaching to the knee, and the women's to the calf of the leg. Their war-dress was thicker, and closely stitched with cotton after the Turkish manner.)—Pet. Martyr, dec. 2 lib. 7. Who were these people described as being comparatively civilized, and clothed with tunics (like those who lived an the summit of the Andes), and seen on a coast, where before and since the time of Pinzon, only naked men have ever been seen?) Gomara and Anghiera wrote from such oral information as they had been able to collect.

These marvels disappear, if we examine the recital which Ferdinand Columbus drew up from his father's papers. There we find simply, that "the admiral was surprised to see the inhabitants of Paria, and those of the island of Trinidad, better made, more civilized (de buena conversacion), and whiter than the natives whom he had previously seen."* (* Churchill's Collection volume 2, Herrera pages 80, 83, 84. Munoz, Hist. del Nuevo Mundo volume 1, "El color era baxo como es regular en los Indios, pero mas clara que en las islas reconocidas." (Their colour was dark, as is usual among the Indians; but lighter than that of the people of the islands previously known.) The missionaries are accustomed to call those Indians who are less black, less tawny, WHITISH, and even ALMOST WHITE.—Gumilla, Hist. de l'Orenoque volume 1 chapter 5 paragraph 2. Such incorrect expressions may mislead those who are not accustomed to the exaggerations in which travellers often indulge.) This certainly did not mean that the Pariagotos are white. The lighter colour of the skin of the natives and the great coolness of the mornings on the coast of Paria, seemed to confirm the fantastic hypothesis which that great man had framed, respecting the irregularity of the curvature of the earth, and the height of the plains in this region, which he regarded as the effect of an extraordinary swelling of the globe in the direction of the parallels of latitude. Amerigo Vespucci (in his pretended FIRST voyage, apparently written from the narratives of other navigators) compares the natives to the Tartar nations,* (* Vultu non multum speciosi sunt, quoniam latas facies Tartariis adsimilatas habent. (Their countenances are not handsome, their cheek-bones being broad like those of the Tartars.)—Americi Vesputii Navigatio Prima, in Gryn's Orbis Novus 1555.) not in regard to their colour, but on account of the breadth of their faces, and the general expression of their physiognomy.

But if it be certain, that at the end of the fifteenth century there were on the coast of Cumana a few men with white skins, as there are in our days, it must not thence be concluded, that the natives of the New World exhibit everywhere a similar organization of the dermoidal system. It is not less inaccurate to say, that they are all copper-coloured, than to affirm that they would not have a tawny hue, if they were not exposed to the heat of the sun, or tanned by the action of the air. The natives may be divided into two very unequal portions with respect to numbers; to the first belong the Esquimaux of Greenland, of Labrador, and the northern coast of Hudson's Bay, the inhabitants of Behring's Straits, of the peninsula of Alaska, and of Prince William's Sound. The eastern and western branches* of this polar race (* Vater, in Mithridates volume 3. Egede, Krantz, Hearne, Mackenzie, Portlock, Chwostoff, Davidoff, Resanoff, Merk, and Billing, have described the great family of these Tschougaz-Esquimaux.), the Esquimaux and the Tschougases, though at the vast distance of eight hundred leagues apart, are united by the most intimate analogy of languages. This analogy extends even to the inhabitants of the north-east of Asia; for the idiom of the Tschouktsches* at the mouth of the Anadir (* I mean here only the Tschouktsches who have fixed dwelling-places, for the wandering Tschouktsches approach very near the Koriaks.), has the same roots as the language of the Esquimaux who inhabit the coast of America opposite to Europe. The Tschouktsches are the Esquimaux of Asia. Like the Malays, that hyperborean race reside only on the sea-coasts. They are almost all smaller in stature than the other Americans, and are quick, lively, and talkative. Their hair is almost straight, and black; but their skin (and this is very characteristic of the race, which I shall designate under the name of Tschougaz-Esquimaux) is originally whitish. It is certain that the children of the Greenlanders are born white; some retain that whiteness; and often in the brownest (the most tanned) the redness of the blood is seen to appear on their cheeks.* (* Krantz, Hist. of Greenland 1667 tome 1. Greenland does not seem to have been inhabited in the eleventh century; at least the Esquimaux appeared only in the fourteenth, coming from the west.)

The second portion of the natives of America includes all those nations which are not Tschougaz-Esquimaux, beginning from Cook's River to the Straits of Magellan, from the Ugaljachmouzes and the Kinaese of Mount St. Elias, to the Puelches and Tehuelhets of the southern hemisphere. The men who belong to this second branch, are taller, stronger, more warlike, and more taciturn than the others. They present also very remarkable differences in the colour of their skin. In Mexico, Peru, New Grenada, Quito, on the banks of the Orinoco and of the river Amazon, in every part of South America which I have explored, in the plains as well as on the coldest table-lands, the Indian children of two or three months old have the same bronze tint as is observed in adults. The idea that the natives may be whites tanned by the air and the sun, could never have occurred to a Spanish inhabitant of Quito, or of the banks of the Orinoco. In the north-east of America, on the contrary, we meet with tribes among whom the children are white, and at the age of virility they acquire the bronze colour of the natives of Mexico and Peru. Michikinakoua, chief of the Miamis, had his arms, and those parts of his body not exposed to the sun, almost white. This difference of hue between the parts covered and not covered is never observed among the natives of Peru and Mexico, even in families who live much at their ease, and remain almost constantly within doors. To the west of the Miamis, on the coast opposite to Asia, among the Kolouches and Tchinkitans* of Norfolk Sound (* Between 54 and 58 degrees of latitude. These white nations have been visited successively by Portlock, Marchand, Baranoff, and Davidoff. The Tchinkitans, or Schinkit, are the inhabitants of the island of Sitka. Vater Mithridates volume 3 page 2. Marchand Voyages volume 2.), grown-up girls, when they have gashed their skin, display the white hue of Europeans. This whiteness is found also, according to some accounts, among the mountaineers of Chile.* (* Molina, Saggio sull' Istoria Nat. del Chile edition 2 page 293. May we believe the existence of those blue eyes of the Boroas of Chile and Guayanas of Uruguay; represented to us as nations of the race of Odin? Azara Voyage tome 2.)

These facts are very remarkable, and contrary to the opinion so generally spread, of the extreme conformity of organization among the natives of America. If we divide them into Esquimaux and non-Esquimaux, we readily admit that this classification is not more philosophical than that of the ancients, who saw in the whole of the habitable world only Celts and Scythians, Greeks, and Barbarians. When, however, our purpose is to group numerous nations, we gain something by proceeding in the mode of exclusion. All we have sought to establish here is, that, in separating the whole race of Tschougaz-Esquimaux, there remain still, among the coppery-brown Americans, other races, the children of which are born white, without our being able to prove, by going back as far as the history of the Conquest, that they have been mingled with European blood. This fact deserves to be cleared up by travellers who may possess a knowledge of physiology, and may have opportunities of examining the brown children of the Mexicans at the age of two years, as well as the white children of the Miamis, and those hordes* on the Orinoco (* These whitish tribes are the Guaycas, the Ojos, and the Maquiritares.), who, living in the most sultry regions, retain during their whole life, and in the fulness of their strength, the whitish skin of the Mestizoes.

In man, the deviations from the common type of the whole race are apparent in the stature, the physiognomy, or the form of the body, rather than on the colour of the skin.* (* The circumpolar nations of the two continents are small and squat, though of races entirely different.) It is not so with animals, where varieties are found more in colour than in form. The hair of the mammiferous class of animals, the feathers of birds, and even the scales of fishes, change their hue, according to the lengthened influence of light and darkness, and the intensity of heat and cold. In man, the colouring matter seems to be deposited in the epidermis by the roots or the bulbs of the hair:* (* Adverting to the interesting researches of M. Gaultier, on the organisation of the human skin, John Hunter observes, that in several animals the colorating of the hair is independent of that of the skin.) and all sound observations prove, that the skin varies in colour from the action of external stimuli on individuals, and not hereditarily in the whole race. The Esquimaux of Greenland and the Laplanders are tanned by the influence of the air; but their children are born white. We will not decide on the changes which nature may have produced in a space of time exceeding all historical tradition. Reason stops short in these matters, when no longer under the guidance of experience and analogy.

All white-skinned nations begin their cosmogony by white men; they allege that the negroes and all tawny people have been blackened or embrowned by the excessive heat of the sun. This theory, adopted by the Greeks,* (* Strabo, liv. 15.) though it did not pass without contradiction,* (* Onesicritus, apud Strabonem, lib. 15. Alexander's expedition appears to have contributed greatly to fix the attention of the Greeks on the great question of the influence of climates. They had learned from the accounts of travellers, that in Hindostan the nations of the south were of darker colour than those of the north, near the mountains: and they supposed that they were both of the same race.) has been propagated even to our own times. Buffon has repeated in prose what Theodectes had expressed in verse two thousand years before: "that nations wear the livery of the climate in which they live." If history had been written by black nations, they would have maintained what even Europeans have recently advanced,* that man was originally black, or of a very tawny colour (* See the work of Mr. Prichard, abounding with curious research. "Researches into the Physical History of Man, 1813," page 239.); and that mankind have become white in some races, from the effect of civilization and progressive debilitation, as animals, in a state of domestication, pass from dark to lighter colours. In plants and in animals, accidental varieties, formed under our own eyes, have become fixed, and have been propagated;* (* For example, the sheep with very short legs, called ancon sheep in Connecticut, and examined by Sir Everard Home. This variety dates only from the year 1791.) but nothing proves, that in the present state of human organization, the different races of black, yellow, copper-coloured, and white men, when they remain unmixed, deviate considerably from their primitive type, by the influence of climate, of food, and other external agents.

These opinions are founded on the authority of Ulloa.* (* "The Indians [Americans] are of a copper-colour, which by the action of the sun and the air grows darker. I must remark, that neither heat nor cold produces any sensible change in the colour, so that the Indians of the Cordilleras of Peru are easily confounded with those of the hottest plains; and those who live under the Line cannot be distinguished, by their colour, from those who inhabit the fortieth degree of north and south latitude."—Noticias Americanas. No ancient author has so clearly stated the two forms of reasoning, by which we still explain in our days the differences of colour and features among neighbouring nations, as Tacitus. He makes a just distinction between the influence of climate, and hereditary dispositions; and, like a philosopher persuaded of our profound ignorance of the origin of things, he leaves the question undecided. "Habitus corporum varii; atque ex eo argumenta, seu durante originis vi, seu procurrentibus in diversa terris, positio coeli corporibus habitum dedit."—Agricola, cap 2.) That learned writer saw the Indians of Chile, of the Andes of Peru, of the burning coasts of Panama, and those of Louisiana, situated in the northern temperate zone. He had the good fortune to live at a period when theories were less numerous; and, like me, he was struck by seeing the natives equally bronzed under the Line, in the cold climate of the Cordilleras, and in the plains. Where differences of colour are observed, they depend on the race. We shall soon find on the burning banks of the Orinoco Indians with a whitish skin. Durans originis vis est.

CHAPTER 1.10.

SECOND ABODE AT CUMANA. EARTHQUAKES. EXTRAORDINARY METEORS.

We remained a month longer at Cumana, employing ourselves in the necessary preparations for our proposed visit to the Orinoco and the Rio Negro. We had to choose such instruments as could be most easily transported in narrow boats; and to engage guides for an inland journey of ten months, across a country without communication with the coasts. The astronomical determination of places being the most important object of this undertaking, I felt desirous not to miss the observation of an eclipse of the sun, which was to be visible at the end of October: and in consequence I preferred remaining till that period at Cumana, where the sky is generally clear and serene. It was now too late to reach the banks of the Orinoco before October; and the high valleys of Caracas promised less favourable opportunities, on account of the vapours which accumulate round the neighbouring mountains.

I was, however, near being compelled by a deplorable occurrence, to renounce, or at least to delay for a long time, my journey to the Orinoco. On the 27th of October, the day before the eclipse, we went as usual, to take the air on the shore of the gulf, and to observe the instant of high water, which in those parts is only twelve or thirteen inches. It was eight in the evening, and the breeze was not yet stirring. The sky was cloudy; and during a dead calm it was excessively hot. We crossed the beach which separates the suburb of the Guayqueria Indians from the embarcadero. I heard some one walking behind us, and on turning, I saw a tall man of the colour of the Zambos, naked to the waist. He held almost over my head a macana, which is a great stick of palm-tree wood, enlarged to the end like a club. I avoided the stroke by leaping towards the left; but M. Bonpland, who walked on my right, was less fortunate. He did not see the Zambo so soon as I did, and received a stroke above the temple, which levelled him with the ground. We were alone, without arms, half a league from any habitation, on a vast plain bounded by the sea. The Zambo, instead of attacking me, moved off slowly to pick up M. Bonpland's hat, which, having somewhat deadened the violence of the blow, had fallen off and lay at some distance. Alarmed at seeing my companion on the ground, and for some moments senseless, I thought of him only. I helped him to raise himself, and pain and anger doubled his strength. We ran toward the Zambo, who, either from cowardice, common enough in people of this caste, or because he perceived at a distance some men on the beach, did not wait for us, but ran off in the direction of the Tunal, a little thicket of cactus and arborescent avicennia. He chanced to fall in running; and M. Bonpland, who reached him first, seized him round the body. The Zambo drew a long knife; and in this unequal struggle we should infallibly have been wounded, if some Biscayan merchants, who were taking the air on the beach, had not come to our assistance. The Zambo seeing himself surrounded, thought no longer of defence. He again ran away, and we pursued him through the thorny cactuses. At length, tired out, he took shelter in a cow-house, whence he suffered himself to be quietly led to prison.

M. Bonpland was seized with fever during the night; but being endowed with great energy and fortitude, and possessing that cheerful disposition which is one of the most precious gifts of nature, he continued his labours the next day. The stroke of the macana had extended to the top of his head, and he felt its effect for the space of two or three months during the stay we made at Caracas. When stooping to collect plants, he was sometimes seized with giddiness, which led us to fear that an internal abscess was forming. Happily these apprehensions were unfounded, and the symptoms, at first alarming, gradually disappeared. The inhabitants of Cumana showed us the kindest interest. It was ascertained that the Zambo was a native of one of the Indian villages which surround the great lake of Maracaybo. He had served on board a privateer belonging to the island of St. Domingo, and in consequence of a quarrel with the captain he had been left on the coast of Cumana, when the ship quitted the port. Having seen the signal which we had fixed up for the purpose of observing the height of the tides, he had watched the moment when he could attack us on the beach. But why, after having knocked one of us down, was he satisfied with simply stealing a hat? In an examination he underwent, his answers were so confused and stupid, that it was impossible to clear up our doubts. Sometimes he maintained that his intention was not to rob us; but that, irritated by the bad treatment he had suffered on board the privateer of St. Domingo, he could not resist the desire of attacking us, when he heard us speak French. Justice is so tardy in this country, that prisoners, of whom the jail is full, may remain seven or eight years without being brought to trial; we learnt, therefore, with some satisfaction, that a few days after our departure from Cumana, the Zambo had succeeded in breaking out of the castle of San Antonio.

On the day after this occurrence, the 28th of October, I was, at five in the morning, on the terrace of our house, making preparations for the observation of the eclipse. The weather was fine and serene. The crescent of Venus, and the constellation of the Ship, so splendid from the disposition of its immense nebulae, were lost in the rays of the rising sun. I had a complete observation of the progress and the close of the eclipse. I determined the distance of the horns, or the differences of altitude and azimuth, by the passage over the threads of the quadrant. The eclipse terminated at 2 hours 14 minutes 23.4 seconds mean time, at Cumana.

During a few days which preceded and followed the eclipse of the sun, very remarkable atmospherical phenomena were observable. It was what is called in those countries the season of winter; that is, of clouds and small electrical showers. From the 10th of October to the 3rd of November, at nightfall, a reddish vapour arose in the horizon, and covered, in a few minutes, with a veil more or less thick, the azure vault of the sky. Saussure's hygrometer, far from indicating greater humidity, often went back from 90 to 83 degrees. The heat of the day was from 28 to 32 degrees, which for this part of the torrid zone is very considerable. Sometimes, in the midst of the night, the vapours disappeared in an instant; and at the moment when I had arranged my instruments, clouds of brilliant whiteness collected at the zenith, and extended towards the horizon. On the 18th of October these clouds were so remarkably transparent, that they did not hide stars even of the fourth magnitude. I could distinguish so perfectly the spots of the moon, that it might have been supposed its disk was before the clouds. The latter were at a prodigious height, disposed in bands, and at equal distances, as from the effect of electric repulsions:—these small masses of vapour, similar to those I saw above my head on the ridge of the highest Andes, are, in several languages, designated by the name of sheep. When the reddish vapour spreads lightly over the sky, the great stars, which in general, at Cumana, scarcely scintillate below 20 or 25 degrees, did not retain even at the zenith, their steady and planetary light. They scintillated at all altitudes, as after a heavy storm of rain.* (* I have not observed any direct relation between the scintillation of the stars and the dryness of that part of the atmosphere open to our researches. I have often seen at Cumana a great scintillation of the stars of Orion and Sagittarius, when Saussure's hygrometer was at 85 degrees. At other times, these same stars, considerably elevated above the horizon, emitted a steady and planetary light, the hygrometer being at 90 or 93 degrees. Probably it is not the quantity of vapour, but the manner in which it is diffused, and more or less dissolved in the air, which determines the scintillation. The latter is invariably attended with a coloration of light. It is remarkable enough, that, in northern countries, at a time when the atmosphere appears perfectly dry, the scintillation is most decided in very cold weather.) It was curious that the vapour did not affect the hygrometer at the surface of the earth. I remained a part of the night seated in a balcony, from which I had a view of a great part of the horizon. In every climate I feel a peculiar interest in fixing my eyes, when the sky is serene, on some great constellation, and seeing groups of vesicular vapours appear and augment, as around a central nucleus, then, disappearing, form themselves anew.

After the 28th of October, the reddish mist became thicker than it had previously been. The heat of the nights seemed stifling, though the thermometer rose only to 26 degrees. The breeze, which generally refreshed the air from eight or nine o'clock in the evening, was no longer felt. The atmosphere was burning hot, and the parched and dusty ground was cracked on every side. On the 4th of November, about two in the afternoon, large clouds of peculiar blackness enveloped the high mountains of the Brigantine and the Tataraqual. They extended by degrees as far as the zenith. About four in the afternoon thunder was heard over our heads, at an immense height, not regularly rolling, but with a hollow and often interrupted sound. At the moment of the strongest electric explosion, at 4 hours 12 minutes, there were two shocks of earthquake, which followed each other at the interval of fifteen seconds. The people ran into the streets, uttering loud cries. M. Bonpland, who was leaning over a table examining plants, was almost thrown on the floor. I felt the shock very strongly, though I was lying in a hammock. Its direction was from north to south, which is rare at Cumana. Slaves, who were drawing water from a well more than eighteen or twenty feet deep, near the river Manzanares, heard a noise like the explosion of a strong charge of gunpowder. The noise seemed to come from the bottom of the well; a very curious phenomenon, though very common in most of the countries of America which are exposed to earthquakes.

A few minutes before the first shock there was a very violent blast of wind, followed by electrical rain falling in great drops. I immediately tried the atmospherical electricity by the electrometer of Volta. The small balls separated four lines; the electricity often changed from positive to negative, as is the case during storms, and, in the north of Europe, even sometimes in a fall of snow. The sky remained cloudy, and the blast of wind was followed by a dead calm, which lasted all night. The sunset presented a picture of extraordinary magnificence. The thick veil of clouds was rent asunder, as in shreds, quite near the horizon; the sun appeared at 12 degrees of altitude on a sky of indigo-blue. Its disk was enormously enlarged, distorted, and undulated toward the edges. The clouds were gilded; and fascicles of divergent rays, reflecting the most brilliant rainbow hues, extended over the heavens. A great crowd of people assembled in the public square. This celestial phenomenon,—the earthquake,—the thunder which accompanied it,—the red vapour seen during so many days, all were regarded as the effect of the eclipse.

About nine in the evening there was another shock, much slighter than the former, but attended with a subterraneous noise. The barometer was a little lower than usual; but the progress of the horary variations or small atmospheric tides, was no way interrupted. The mercury was precisely at the minimum of height at the moment of the earthquake; it continued rising till eleven in the evening, and sank again till half after four in the morning, conformably to the law which regulates barometrical variations. In the night between the 3rd and 4th of November the reddish vapour was so thick that I could not distinguish the situation of the moon, except by a beautiful halo of 20 degrees diameter.

Scarcely twenty-two months had elapsed since the town of Cumana had been almost totally destroyed by an earthquake. The people regard vapours which obscure the horizon, and the subsidence of wind during the night, as infallible pregnostics of disaster. We had frequent visits from persons who wished to know whether our instruments indicated new shocks for the next day; and alarm was great and general when, on the 5th of November, exactly at the same hour as on the preceding day, there was a violent gust of wind, attended by thunder, and a few drops of rain. No shock was felt. The wind and storm returned during five or six days at the same hour, almost at the same minute. The inhabitants of Cumana, and of many other places between the tropics, have long since observed that atmospherical changes, which are, to appearance, the most accidental, succeed each other for whole weeks with astonishing regularity. The same phenomenon occurs in summer, in the temperate zone; nor has it escaped the perception of astronomers, who often observe, in a serene sky, during three or four days successively, clouds which have collected at the same part of the firmament, take the same direction, and dissolve at the same height; sometimes before, sometimes after the passage of a star over the meridian, consequently within a few minutes of the same point of true time.* (* M. Arago and I paid a great deal of attention to this phenomenon during a long series of observations made in the year 1809 and 1810, at the Observatory of Paris, with the view of verifying the declination of the stars.)

The earthquake of the 4th of November, the first I had felt, made the greater impression on me, as it was accompanied with remarkable meteorological variations. It was, moreover, a positive movement upward and downward, and not a shock by undulation. I did not then imagine, that after a long abode on the table-lands of Quito and the coasts of Peru, I should become almost as familiar with the abrupt movements of the ground as we are in Europe with the sound of thunder. In the city of Quito, we never thought of rising from our beds when, during the night, subterraneous rumblings (bramidos), which seem always to come from the volcano of Pichincha, announced a shock, the force of which, however, is seldom in proportion to the intensity of the noise. The indifference of the inhabitants, who bear in mind that for three centuries past their city has not been destroyed, readily communicates itself to the least intrepid traveller. It is not so much the fear of the danger, as the novelty of the sensation, which makes so forcible an impression when the effect of the slightest earthquake is felt for the first time.

From our infancy, the idea of certain contrasts becomes fixed in our minds: water appears to us an element that moves; earth, a motionless and inert mass. These impressions are the result of daily experience; they are connected with everything that is transmitted to us by the senses. When the shock of an earthquake is felt, when the earth which we had deemed so stable is shaken on its old foundations, one instant suffices to destroy long-fixed illusions. It is like awakening from a dream; but a painful awakening. We feel that we have been deceived by the apparent stability of nature; we become observant of the least noise; we mistrust for the first time the soil we have so long trod with confidence. But if the shocks be repeated, if they become frequent during several successive days, the uncertainty quickly disappears. In 1784, the inhabitants of Mexico were accustomed to hear the thunder roll beneath their feet,* (* Los bramidos de Guanazuato.) as it is heard by us in the region of the clouds. Confidence easily springs up in the human breast: on the coasts of Peru we become accustomed to the undulations of the ground, as the sailor becomes accustomed to the tossing of the ship, caused by the motion of the waves.

The reddish vapour which at Cumana had spread a mist over the horizon a little before sunset, disappeared after the 7th of November. The atmosphere resumed its former purity, and the firmament appeared, at the zenith, of that deep blue tint peculiar to climates where heat, light, and a great equality of electric charge seem all to promote the most perfect dissolution of water in the air. I observed, on the night of the 7th, the immersion of the second satellite of Jupiter. The belts of the planet were more distinct than I had ever seen them before.

I passed a part of the night in comparing the intensity of the light emitted by the beautiful stars which shine in the southern sky. I pursued this task carefully in both hemispheres, at sea, and during my abode at Lima, at Guayaquil, and at Mexico. Nearly half a century has now elapsed since La Caille examined that region of the sky which is invisible in Europe. The stars near the south pole are usually observed with so little perseverance and attention, that the greatest changes may take place in the intensity of their light and their own motion, without astronomers having the slightest knowledge of them. I think I have remarked changes of this kind in the constellation of the Crane and in that of the Ship. I compared, at first with the naked eye, the stars which are not very distant from each other, for the purpose of classing them according to the method pointed out by Herschel, in a paper read to the Royal Society of London in 1796. I afterwards employed diaphragms diminishing the aperture of the telescope, and coloured and colourless glasses placed before the eye-glass. I moreover made use of an instrument of reflexion calculated to bring simultaneously two stars into the field of the telescope, after having equalized their light by receiving it with more or fewer rays at pleasure, reflected by the silvered part of the mirror. I admit that these photometric processes are not very precise; but I believe the last, which perhaps had never before been employed, might he rendered nearly exact, by adding a scale of equal parts to the moveable frame of the telescope of the sextant. It was by taking the mean of a great number of valuations, that I saw the relative intensity of the light of the great stars decrease in the following manner: Sirius, Canopus, a Centauri, Acherner, b Centauri, Fomalhaut, Rigel, Procyon, Betelgueuse, e of the Great Dog, d of the Great Dog, a of the Crane, a of the Peacock. These experiments will become more interesting when travellers shall have determined anew, at intervals of forty or fifty years, some of those changes which the celestial bodies seem to undergo, either at their surface or with respect to their distances from our planetary system.

After having made astronomical observations with the same instruments, in our northern climates and in the torrid zone, we are surprised at the effect produced in the latter (by the transparency of the air, and the less extinction of light), on the clearness with which the double stars, the satellites of Jupiter, or certain nebulae, present themselves. Beneath a sky equally serene in appearance, it would seem as if more perfect instruments were employed; so much more distinct and well defined do the objects appear between the tropics. It cannot be doubted, that at the period when equinoctial America shall become the centre of extensive civilization, physical astronomy will make immense improvements, in proportion as the skies will be explored with excellent glasses, in the dry and hot climates of Cumana, Coro, and the island of Margareta. I do not here mention the ridge of the Cordilleras, because, with the exception of some high and nearly barren plains in Mexico and Peru, the very elevated table-lands, in which the barometric pressure is from ten to twelve inches less than at the level of the sea, have a misty and extremely variable climate. The extreme purity of the atmosphere which constantly prevails in the low regions during the dry season, counterbalances the elevation of site and the rarity of the air on the table-lands. The elevated strata of the atmosphere, when they envelope the ridges of mountains, undergo rapid changes in their transparency.

The night of the 11th of November was cool and extremely fine. From half after two in the morning, the most extraordinary luminous meteors were seen in the direction of the east. M. Bonpland, who had risen to enjoy the freshness of the air, perceived them first. Thousands of bolides and falling stars succeeded each other during the space of four hours. Their direction was very regular from north to south. They filled a space in the sky extending from due east 30 degrees to north and south. In an amplitude of 60 degrees the meteors were seen to rise above the horizon at east-north-east and at east, to describe arcs more or less extended, and to fall towards the south, after having followed the direction of the meridian. Some of them attained a height of 40 degrees, and all exceeded 25 or 30 degrees. There was very little wind in the low regions of the atmosphere, and that little blew from the east. No trace of clouds was to be seen. M. Bonpland states that, from the first appearance of the phenomenon, there was not in the firmament a space equal in extent to three diameters of the moon, which was not filled every instant with bolides and falling stars. The first were fewer in number, but as they were of different sizes, it was impossible to fix the limit between these two classes of phenomena. All these meteors left luminous traces from five to ten degrees in length, as often happens in the equinoctial regions. The phosphorescence of these traces, or luminous bands, lasted seven or eight seconds. Many of the falling stars had a very distinct nucleus, as large as the disk of Jupiter, from which darted sparks of vivid light. The bolides seem to burst as by explosion; but the largest, those from 1 to 1 degree 15 minutes in diameter, disappeared without scintillation, leaving behind them phosphorescent bands (trabes) exceeding in breadth fifteen or twenty minutes. The light of these meteors was white, and not reddish, which must doubtless be attributed to the absence of vapour and the extreme transparency of the air. For the same reason, within the tropics, the stars of the first magnitude have, at their rising, a light decidedly whiter than in Europe.

Almost all the inhabitants of Cumana witnessed this phenomenon, because they had left their houses before four o'clock, to attend the early morning mass. They did not behold these bolides with indifference; the oldest among them remembered that the great earthquakes of 1766 were preceded by similar phenomena. The Guaiqueries in the Indian suburb alleged "that the bolides began to appear at one o'clock; and that as they returned from fishing in the gulf, they had perceived very small falling stars towards the east." They assured us that igneous meteors were extremely rare on those coasts after two o'clock in the morning.

The phenomenon ceased by degrees after four o'clock, and the bolides and falling stars became less frequent; but we still distinguished some to north-east by their whitish light, and the rapidity of their movement, a quarter of an hour after sunrise. This circumstance will appear less extraordinary, when I mention that in broad daylight, in 1788, the interior of the houses in the town of Popayan was brightly illumined by an aerolite of immense magnitude. It passed over the town, when the sun was shining clearly, about one o'clock. M. Bonpland and myself, during our second residence at Cumana, after having observed, on the 26th of September, 1800, the immersion of the first satellite of Jupiter, succeeded in seeing the planet distinctly with the naked eye, eighteen minutes after the disk of the sun had appeared in the horizon. There was a very slight vapour in the east, but Jupiter appeared on an azure sky. These facts bear evidence of the extreme purity and transparency of the atmosphere in the torrid zone. The mass of diffused light is the less, in proportion as the vapours are more perfectly dissolved. The same cause which checks the diffusion of the solar light, diminishes the extinction of that which emanates either from bolides from Jupiter, or from the moon, seen on the second day after its conjunction. The 12th of November was an extremely hot day, and the hygrometer indicated a very considerable degree of dryness for those climates. The reddish vapour clouded the horizon anew, and rose to the height of 14 degrees. This was the last time it appeared that year; and I must here observe, that it is no less rare under the fine sky of Cumana, than it is common at Acapulco, on the western coast of Mexico.

We did not neglect, during the course of our journey from Caracas to the Rio Negro, to enquire everywhere, whether the meteors of the 12th of November had been perceived. In a wild country, where the greater number of the inhabitants sleep in the open air, so extraordinary a phenomenon could not fail to be remarked, unless it had been concealed from observation by clouds. The Capuchin missionary at San Fernando de Apure,* (* North latitude 7 degrees 53 minutes 12 seconds; west longitude 70 degrees 20 minutes.), a village situated amid the savannahs of the province of Varinas; the Franciscan monks stationed near the cataracts of the Orinoco and at Maroa,* (* North latitude 2 degrees 42 minutes 0 seconds; west longitude 70 degrees 21 minutes.) on the banks of the Rio Negro; had seen numberless falling-stars and bolides illumine the heavens. Maroa is south-west of Cumana, at one hundred and seventy-four leagues distance. All these observers compared the phenomenon to brilliant fireworks; and it lasted from three till six in the morning. Some of the monks had marked the day in their rituals; others had noted it by the proximate festivals of the Church. Unfortunately, none of them could recollect the direction of the meteors, or their apparent height. From the position of the mountains and thick forests which surround the Missions of the Cataracts and the little village of Maroa, I presume that the bolides were still visible at 20 degrees above the horizon. On my arrival at the southern extremity of Spanish Guiana, at the little fort of San Carlos, I found some Portuguese, who had gone up the Rio Negro from the Mission of St. Joseph of the Maravitans. They assured me that in that part of Brazil the phenomenon had been perceived at least as far as San Gabriel das Cachoeiras, consequently as far as the equator itself.* (* A little to the north-west of San Antonio de Castanheiro. I did not meet with any persons who had observed this meteor, at Santa Fe de Bogota, at Popayan, or in the southern hemisphere, at Quito and Peru. Perhaps the state of the atmosphere, so changeable in these western regions, prevented observation.)

I was forcibly struck by the immense height which these bolides must have attained, to have rendered them visible simultaneously at Cumana, and on the frontiers of Brazil, in a line of two hundred and thirty leagues in length. But what was my astonishment, when, on my return to Europe, I learned that the same phenomenon had been perceived on an extent of the globe of 64 degrees of latitude, and 91 degrees of longitude; at the equator, in South America, at Labrador, and in Germany! I saw accidentally, during my passage from Philadelphia to Bordeaux,* (* In the Memoirs of the Pennsylvanian Society.) the corresponding observation of Mr. Ellicot (latitude 30 degrees 42); and upon my return from Naples to Berlin, I read the account of the Moravian missionaries among the Esquimaux, in the Bibliothek of Gottingen.

The following is a succinct enumeration of the facts:

First. The fiery meteors were seen in the east, and the east-north-east, at 40 degrees of elevation, from 2 to 6 a.m. at Cumana (latitude 10 degrees 27 minutes 52 seconds, longitude 66 degrees 30 minutes); at Porto Cabello (latitude 10 degrees 6 minutes 52 seconds, longitude 67 degrees 5 minutes); and on the frontiers of Brazil, near the equator, in longitude 70 degrees west of the meridian of Paris.

Second. In French Guiana (latitude 4 degrees 56 minutes, longitude 54 degrees 35 minutes) "the northern part of the sky was suffused with fire. Numberless falling-stars traversed the heavens during the space of an hour and a half, and shed so vivid a light, that those meteors might be compared to the blazing sheaves which shoot out from fireworks." The knowledge of this fact rests upon the highly trustworthy testimony of the Count de Marbois, then living in exile at Cayenne, a victim to his love of justice and of rational, constitutional liberty.

Third. Mr. Ellicot, astronomer to the United States, having completed his trigonometric operations for the rectification of the limits on the Ohio, being on the 12th of November in the gulf of Florida, in latitude 25 degrees, and longitude 81 degrees 50 minutes, saw in all parts of the sky, "as many meteors as stars, moving in all directions. Some appeared to fall perpendicularly; and it was expected every minute that they would drop into the vessel." The same phenomenon was perceived upon the American continent as far as latitude 30 degrees 42 minutes.

Fourth. In Labrador, at Nain (latitude 56 degrees 55 minutes), and Hoffenthal (latitude 58 degrees 4 minutes); in Greenland, at Lichtenau (latitude 61 degrees 5 minutes), and at New Herrnhut (latitude 64 degrees 14 minutes, longitude 52 degrees 20 minutes); the Esquimaux were terrified at the enormous quantity of bolides which fell during twilight at all points of the firmament, and some of which were said to be a foot broad.

Fifth. In Germany, Mr. Zeissing, vicar of Ittetsadt, near Weimar (latitude 50 degrees 59 minutes, longitude 9 degrees 1 minute east), perceived, on the 12th of November, between the hours of six and seven in the morning (half-past two at Cumana), some falling-stars which shed a very white light. Soon after, in the direction of south and south-west, luminous rays appeared from four to six feet long; they were reddish, and resembled the luminous track of a sky-rocket. During the morning twilight, between the hours of seven and eight, the sky, in the direction of south-west, was observed from time to time to be brightly illumined by white lightning, running in serpentine lines along the horizon. At night the cold increased and the barometer rose. It is very probable, that the meteors might have been observed more to the east, in Poland and in Russia.* (* In Paris and in London the sky was cloudy. At Carlsruhe, before dawn, lightning was seen in the north-west and south-east. On the 13th of November a remarkable glare of light was seen at the same place in the south-east.)

The distance from Weimar to the Rio Negro is 1800 nautical leagues; and from the Rio Negro to Herrnhut in Greenland, 1300 leagues. Admitting that the same fiery meteors were seen at points so distant from each other, we must suppose that their height was at least 411 leagues. Near Weimar, the appearance like sky-rockets was observed in the south and south-east; at Cumana, in the east and east-north-east. We may therefore conclude, that numberless aerolites must have fallen into the sea, between Africa and South America, westward of the Cape Verd Islands. But since the direction of the bolides was not the same at Labrador and at Cumana, why were they not perceived in the latter place towards the north, as at Cayenne? We can scarcely be too cautious on a subject, on which good observations made in very distant places are still wanting. I am rather inclined to think, that the Chayma Indians of Cumana did not see the same bolides as the Portuguese in Brazil and the missionaries in Labrador; but at the same time it cannot be doubted (and this fact appears to me very remarkable) that in the New World, between the meridians of 46 and 82 degrees, between the equator and 64 degrees north, at the same hour, an immense number of bolides and falling-stars were perceived; and that those meteors had everywhere the same brilliancy, throughout a space of 921,000 square leagues.

Astronomers who have lately been directing minute attention to falling-stars and their parallaxes, consider them as meteors belonging to the farthest limits of our atmosphere, between the region of the Aurora Borealis and that of the lightest clouds.* (* According to the observations which I made on the ridge of the Andes, at an elevation of 2700 toises, on the moutons, or little white fleecy clouds, it appeared to me, that their elevation is sometimes not less than 6000 toises above the level of the coast.) Some have been seen, which had not more than 14,000 toises, or about five leagues of elevation. The highest do not appear to exceed thirty leagues. They are often more than a hundred feet in diameter: and their swiftness is such, that they dart in a few seconds through a space of two leagues. Of some which have been measured, the direction was almost perpendicularly upward, or forming an angle of 50 degrees with the vertical line. This extremely remarkable circumstance has led to the conclusion, that falling-stars are not aerolites which, after having hovered a long time in space, unite on accidentally entering into our atmosphere, and fall towards the earth.* (* M. Chladni, who at first considered falling-stars to be aerolites, subsequently abandoned that idea.)

Whatever may be the origin of these luminous meteors, it is difficult to conceive an instantaneous inflammation taking place in a region where there is less air than in the vacuum of our air-pumps; and where (at the height of 25,000 toises) the mercury in the barometer would not rise to 0.012 of a line. We have ascertained the uniform mixture of atmospheric air to be about 0. 003, only to an elevation of 3000 toises; consequently not beyond the last stratum of fleecy clouds. It may be admitted that, in the first revolutions of the globe, gaseous substances, which yet remain unknown to us, have risen towards that region through which the falling-stars pass; but accurate experiments, made upon mixtures of gases which have not the same specific gravity, show that there is no reason for supposing a superior stratum of the atmosphere entirely different from the inferior strata. Gaseous substances mingle and penetrate each other on the least movement; and a uniformity of their mixture may have taken place in the lapse of ages, unless we believe them to possess a repulsive action of which there is no example in those substances we can subject to our observations. Farther, if we admit the existence of particular aerial fluids in the inaccessible regions of luminous meteors, of falling-stars, bolides, and the Aurora Borealis; how can we conceive why the whole stratum of those fluids does not at once ignite, but that the gaseous emanations, like the clouds, occupy only limited spaces? How can we suppose an electrical explosion without some vapours collected together, capable of containing unequal charges of electricity, in air, the mean temperature of which is perhaps 25 degrees below the freezing point of the centigrade thermometer, and the rarefaction of which is so considerable, that the compression of the electrical shock could scarcely disengage any heat? These difficulties would in great part be removed, if the direction of the movement of falling-stars allowed us to consider them as bodies with a solid nucleus, as cosmic phenomena (belonging to space beyond the limits of our atmosphere), and not as telluric phenomena (belonging to our planet only).

Supposing the meteors of Cumana to have been only at the usual height at which falling-stars in general move, the same meteors were seen above the horizon in places more than 310 leagues distant from each other.* (* It was this circumstance that induced Lambert to propose the observation of falling-stars for the determination of terrestrial longitudes. He considered them to be celestial signals seen at great distances.) How great a disposition to incandescence must have prevailed on the 12th November, in the higher regions of the atmosphere, to have rendered during four hours myriads of bolides and falling stars visible at the equator, in Greenland, and in Germany!

M. Benzenberg observes, that the same cause which renders the phenomenon more frequent, has also an influence on the large size of the meteors, and the intensity of their light. In Europe, the greatest number of falling stars are seen on those nights on which very bright ones are mingled with very small ones. The periodical nature of the phenomenon augments the interest it excites. There are months in which M. Brandes has reckoned in our temperate zone only sixty or eighty falling-stars in one night; and in other months their number has risen to two thousand. Whenever one is observed, which has the diameter of Sirius or of Jupiter, we are sure of seeing the brilliant meteor succeeded by a great number of smaller ones. If the falling stars be very numerous during one night, it is probable that they will continue equally so during several weeks. It would seem, that in the higher regions of the atmosphere, near that extreme limit where the centrifugal force is balanced by gravity, there exists at regular periods a particular disposition for the production of bolides, falling-stars, and the Aurora Borealis.* (* Ritter, like several others, makes a distinction between bolides mingled with falling-stars and those luminous meteors which, enveloped in vapour and smoke, explode with great noise, and let fall (chiefly in the day-time) aerolites. The latter certainly do not belong to our atmosphere.) Does the periodical recurrence of this great phenomenon depend upon the state of the atmosphere? or upon something which the atmosphere receives from without, while the earth advances in the ecliptic? Of all this we are still as ignorant as mankind were in the days of Anaxagoras.

With respect to the falling-stars themselves, it appears to me, from my own experience, that they are more frequent in the equinoctial regions than in the temperate zone; and more frequent above continents, and near certain coasts, than in the middle of the ocean. Do the radiation of the surface of the globe, and the electric charge of the lower regions of the atmosphere (which varies according to the nature of the soil and the positions of the continents and seas), exert their influence as far as those heights where eternal winter reigns? The total absence of even the smallest clouds, at certain seasons, or above some barren plains destitute of vegetation, seems to prove that this influence can be felt as far as five or six thousand toises high.

A phenomenon analogous to that which appeared on the 12th of November at Cumana, was observed thirty years previously on the table-land of the Andes, in a country studded with volcanoes. In the city of Quito there was seen in one part of the sky, above the volcano of Cayamba, such great numbers of falling-stars, that the mountain was thought to be in flames. This singular sight lasted more than an hour. The people assembled in the plain of Exido, which commands a magnificent view of the highest summits of the Cordilleras. A procession was on the point of setting out from the convent of San Francisco, when it was perceived that the blaze on the horizon was caused by fiery meteors, which ran along the skies in all directions, at the altitude of twelve or thirteen degrees.

CHAPTER 1.11.

PASSAGE FROM CUMANA TO LA GUAYRA. MORRO OF NUEVA BARCELONA. CAPE CODERA. ROAD FROM LA GUAYRA TO CARACAS.

On the 16th of November, at eight in the evening, we were under sail to proceed along the coast from Cumana to the port of La Guayra, whence the inhabitants of the province of Venezuela export the greater part of their produce. The passage is only a distance of sixty leagues, and it usually occupies from thirty-six to forty hours. The little coasting vessels are favoured at once by the wind and by the currents, which run with more or less force from east to west, along the coasts of Terra Firma, particularly from cape Paria to the cape of Chichibacoa. The road by land from Cumana to New Barcelona, and thence to Caracas, is nearly in the same state as that in which it was before the discovery of America. The traveller has to contend with the obstacles presented by a miry soil, large scattered rocks, and strong vegetation. He must sleep in the open air, pass through the valleys of the Unare, the Tuy, and the Capaya, and cross torrents which swell rapidly on account of the proximity of the mountains. To these obstacles must be added the dangers arising from the extreme insalubrity of the country. The very low lands, between the sea-shore and the chain of hills nearest the coast, from the bay of Mochima as far as Coro, are extremely unhealthy. But the last-mentioned town, which is surrounded by an immense wood of thorny cactuses, owes its great salubrity, like Cumana, to its barren soil and the absence of rain.

In returning from Caracas to Cumana, the road by land is sometimes preferred to the passage by sea, to avoid the adverse current. The postman from Caracas is nine days in performing this journey. We often saw persons, who had followed him, arrive at Cumana ill of nervous and miasmatic fevers. The tree of which the bark* furnishes a salutary remedy for those fevers (* Cortex Angosturae of our pharmacopaeias, the bark of the Bonplandia trifoliata.), grows in the same valleys, and upon the edge of the same forests which send forth the pernicious exhalations. M. Bonpland recognised the cuspare in the vegetation of the gulf of Santa Fe, situated between the ports of Cumana and Barcelona. The sickly traveller may perchance repose in a cottage, the inhabitants of which are ignorant of the febrifuge qualities of the trees that shade the surrounding valleys.

Having proceeded by sea from Cumana to La Guayra, we intended to take up our abode in the town of Caracas, till the end of the rainy season. From Caracas we proposed to direct our course across the great plains or llanos, to the Missions of the Orinoco; to go up that vast river, to the south of the cataracts, as far as the Rio Negro and the frontiers of Brazil; and thence to return to Cumana by the capital of Spanish Guiana, commonly called, on account of its situation, Angostura, or the Strait. We could not determine the time we might require to accomplish a tour of seven hundred leagues, more than two-thirds of that distance having to be traversed in boats. The only parts of the Orinoco known on the coasts are those near its mouth. No commercial intercourse is kept up with the Missions. The whole of the country beyond the llanos is unknown to the inhabitants of Cumana and Caracas. Some think that the plains of Calabozo, covered with turf, stretch eight hundred leagues southward, communicating with the Steppes or Pampas of Buenos Ayres; others, recalling to mind the great mortality which prevailed among the troops of Iturriaga and Solano, during their expedition to the Orinoco, consider the whole country, south of the cataracts of Atures, as extremely pernicious to health. In a region where travelling is so uncommon, people seem to feel a pleasure in exaggerating to strangers the difficulties arising from the climate, the wild animals, and the Indians. Nevertheless we persisted in the project we had formed. We could rely upon the interest and solicitude of the governor of Cumana, Don Vicente Emparan, as well as on the recommendations of the Franciscan monks, who are in reality masters of the shores of the Orinoco.

Fortunately for us, one of those monks, Juan Gonzales, was at that time in Cumana. This young monk, who was only a lay-brother, was highly intelligent, and full of spirit and courage. He had the misfortune shortly after his arrival on the coast to displease his superiors, upon the election of a new director of the Missions of Piritu, which is a period of great agitation in the convent of New Barcelona. The triumphant party exercised a general retaliation, from which the lay-brother could not escape. He was sent to Esmeralda, the last Mission of the Upper Orinoco, famous for the vast quantity of noxious insects with which the air is continually filled. Fray Juan Gonzales was thoroughly acquainted with the forests which extend from the cataracts towards the sources of the Orinoco. Another revolution in the republican government of the monks had some years before brought him to the coast, where he enjoyed (and most justly) the esteem of his superiors. He confirmed us in our desire of examining the much-disputed bifurcation of the Orinoco. He gave us useful advice for the preservation of our health, in climates where he had himself suffered long from intermitting fevers. We had the satisfaction of finding Fray Juan Gonzales at New Barcelona, on our return from the Rio Negro. Intending to go from the Havannah to Cadiz, he obligingly offered to take charge of part of our herbals, and our insects of the Orinoco; but these collections were unfortunately lost with himself at sea. This excellent young man, who was much attached to us, and whose zeal and courage might have rendered him very serviceable to the missions of his order, perished in a storm on the coast of Africa, in 1801.

The boat which conveyed us from Cumana to La Guayra, was one of those employed in trading between the coasts and the West India Islands. They are thirty feet long, and not more than three feet high at the gunwale; they have no decks, and their burthen is generally from two hundred to two hundred and fifty quintals. Although the sea is extremely rough from Cape Codera to La Guayra, and although the boats have an enormous triangular sail, somewhat dangerous in those gusts which issue from the mountain-passes, no instance has occurred during thirty years, of one of these boats being lost in the passage from Cumana to the coast of Caracas. The skill of the Guaiqueria pilots is so great, that accidents are very rare, even in the frequent trips they make from Cumana to Guadaloupe, or the Danish islands, which are surrounded with breakers. These voyages of 120 or 150 leagues, in an open sea, out of sight of land, are performed in boats without decks, like those of the ancients, without observations of the meridian altitude of the sun, without charts, and generally without a compass. The Indian pilot directs his course at night by the pole-star, and in the daytime by the sun and the wind. I have seen Guaiqueries and pilots of the Zambo caste, who could find the pole-star by the direction of the pointers alpha and beta of the Great Bear, and they seemed to me to steer less from the view of the pole-star itself, than from the line drawn through these stars. It is surprising, that at the first sight of land, they can find the island of Guadaloupe, Santa Cruz, or Porto Rico; but the compensation of the errors of their course is not always equally fortunate. The boats, if they fall to leeward in making land, beat up with great difficulty to the eastward, against the wind and the current.

We descended rapidly the little river Manzanares, the windings of which are marked by cocoa-trees, as the rivers of Europe are sometimes bordered by poplars and old willows. On the adjacent arid land, the thorny bushes, on which by day nothing is visible but dust, glitter during the night with thousands of luminous sparks. The number of phosphorescent insects augments in the stormy season. The traveller in the equinoctial regions is never weary of admiring the effect of those reddish and moveable fires, which, being reflected by limpid water, blend their radiance with that of the starry vault of heaven.

We quitted the shore of Cumana as if it had long been our home. This was the first land we had trodden in a zone, towards which my thoughts had been directed from earliest youth. There is a powerful charm in the impression produced by the scenery and climate of these regions; and after an abode of a few months we seemed to have lived there during a long succession of years. In Europe, the inhabitant of the north feels an almost similar emotion, when he quits even after a short abode the shores of the Bay of Naples, the delicious country between Tivoli and the lake of Nemi, or the wild and majestic scenery of the Upper Alps and the Pyrenees. Yet everywhere in the temperate zone, the effects of vegetable physiognomy afford little contrast. The firs and the oaks which crown the mountains of Sweden have a certain family air in common with those which adorn Greece and Italy. Between the tropics, on the contrary, in the lower regions of both Indies, everything in nature appears new and marvellous. In the open plains and amid the gloom of forests, almost all the remembrances of Europe are effaced; for it is vegetation that determines the character of a landscape, and acts upon the imagination by its mass, the contrast of its forms, and the glow of its colours. In proportion as impressions are powerful and new, they weaken antecedent impressions, and their force imparts to them the character of duration. I appeal to those who, more sensible to the beauties of nature than to the charms of society, have long resided in the torrid zone. How dear, how memorable during life, is the land on which they first disembarked! A vague desire to revisit that spot remains rooted in their minds to the most advanced age. Cumana and its dusty soil are still more frequently present to my imagination, than all the wonders of the Cordilleras. Beneath the bright sky of the south, the light, and the magic of the aerial hues, embellish a land almost destitute of vegetation. The sun does not merely enlighten, it colours the objects, and wraps them in a thin vapour, which, without changing the transparency of the air, renders its tints more harmonious, softens the effects of the light, and diffuses over nature a placid calm, which is reflected in our souls. To explain this vivid impression which the aspect of the scenery in the two Indies produces, even on coasts but thinly wooded, it is sufficient to recollect that the beauty of the sky augments from Naples to the equator, almost as much as from Provence to the south of Italy.

We passed at high water the bar formed at the mouth of the little river Manzanares. The evening breeze gently swelled the waves in the gulf of Cariaco. The moon had not risen, but that part of the milky way which extends from the feet of the Centaur towards the constellation of Sagittarius, seemed to pour a silvery light over the surface of the ocean. The white rock, crowned by the castle of San Antonio, appeared from time to time between the high tops of the cocoa-trees which border the shore; and we soon recognized the coasts only by the scattered lights of the Guaiqueria fishermen.

We sailed at first to north-north-west, approaching the peninsula of Araya; we then ran thirty miles to west and west-south-west. As we advanced towards the shoal that surrounds Cape Arenas and stretches as far as the petroleum springs of Maniquarez, we enjoyed one of those varied sights which the great phosphorescence of the sea so often displays in those climates. Bands of porpoises followed our bark. Fifteen or sixteen of these animals swam at equal distances from each other. When turning on their backs, they struck the surface of the water with their broad tails; they diffused a brilliant light, which seemed like flames issuing from the depth of the ocean.* (* See Views of Nature Bohn's edition page 246.) Each band of porpoises, ploughing the surface of the waters, left behind it a track of light, the more striking as the rest of the sea was not phosphorescent. As the motion of an oar, and the track of the bark, produced on that night but feeble sparks, it is natural to suppose that the vivid phosphorescence caused by the porpoises was owing not only to the stroke of their tails, but also to the gelatinous matter that envelopes their bodies, and is detached by the shock of the waves.

We found ourselves at midnight between some barren and rocky islands, which uprise like bastions in the middle of the sea, and form the group of the Caracas and Chimanas.* (* There are three of the Caracas islands and eight of the Chimanas.) The moon was above the horizon, and lighted up these cleft rocks which are bare of vegetation and of fantastic aspect. The sea here forms a sort of bay, a slight inward curve of the land between Cumana and Cape Codera. The islets of Picua, Picuita, Caracas, and Boracha, appear like fragments of the ancient coast, which stretches from Bordones in the same direction east and west. The gulfs of Mochima and Santa Fe, which will no doubt one day become frequented ports, lie behind those little islands. The rents in the land, the fracture and dip of the strata, all here denote the effects of a great revolution: possibly that which clove asunder the chain of the primitive mountains, and separated the mica-schist of Araya and the island of Margareta from the gneiss of Cape Codera. Several of the islands are visible at Cumana, from the terraces of the houses, and they produce, according to the superposition of layers of air more or less heated, the most singular effects of suspension and mirage. The height of the rocks does not probably exceed one hundred and fifty toises; but at night, when lighted by the moon, they seem to be of a very considerable elevation.

It may appear extraordinary, to find the Caracas Islands so distant from the city of that name, opposite the coast of the Cumanagotos; but the denomination of Caracas denoted at the beginning of the Conquest, not a particular spot, but a tribe of Indians, neighbours of the Tecs, the Taramaynas, and the Chagaragates. As we came very near this group of mountainous islands, we were becalmed; and at sunrise, small currents drifted us toward Boracha, the largest of them. As the rocks rise nearly perpendicular, the shore is abrupt; and in a subsequent voyage I saw frigates at anchor almost touching the land. The temperature of the atmosphere became sensibly higher whilst we were sailing among the islands of this little archipelago. The rocks, heated during the day, throw out at night, by radiation, a part of the heat absorbed. As the sun arose on the horizon, the rugged mountains projected their vast shadows on the surface of the ocean. The flamingoes began to fish in places where they found in a creek calcareous rocks bordered by a narrow beach. All these islands are now entirely uninhabited; but upon one of the Caracas are found wild goats of large size, brown, and extremely swift. Our Indian pilot assured us that their flesh has an excellent flavour. Thirty years ago a family of whites settled on this island, where they cultivated maize and cassava. The father alone survived his children. As his wealth increased, he purchased two black slaves; and by these slaves he was murdered. The goats became wild, but the cultivated plants perished. Maize in America, like wheat in Europe, connected with man since his first migrations, appears to be preserved only by his care. We sometimes see these nutritive gramina disseminate themselves; but when left to nature the birds prevent their reproduction by destroying the seeds.

We anchored for some hours in the road of New Barcelona, at the mouth of the river Neveri, of which the Indian (Cumanagoto) name is Enipiricuar. This river is full of crocodiles, which sometimes extend their excursions into the open sea, especially in calm weather. They are of the species common in the Orinoco, and bear so much resemblance to the crocodile of Egypt, that they have long been confounded together. It may easily be conceived that an animal, the body of which is surrounded with a kind of armour, must be nearly indifferent to the saltness of the water. Pigafetta relates in his journal recently published at Milan that he saw, on the shores of the island of Borneo, crocodiles which inhabit alike land and sea. These facts must be interesting to geologists, since attention has been fixed on the fresh-water formations, and the curious mixture of marine and fluviatile petrifactions sometimes observed in certain very recent rocks.

The port of Barcelona has maintained a very active commerce since 1795. From Barcelona is exported most of the produce of those vast steppes which extend from the south side of the chain of the coast as far as the Orinoco, and in which cattle of every kind are almost as abundant as in the Pampas of Buenos Ayres. The commercial industry of these countries depends on the demand in the West India Islands for salted provision, oxen, mules, and horses. The coasts of Terra Firma being opposite to the island of Cuba, at a distance of fifteen or eighteen days' sail, the merchants of the Havannah prefer, especially in time of peace, obtaining their provision from the port of Barcelona, to the risk of a long voyage in another hemisphere to the mouth of the Rio de la Plata. The situation of Barcelona is singularly advantageous for the trade in cattle. The animals have only three days' journey from the llanos to the port, while it requires eight or nine days to reach Cumana, on account of the chain of mountains of the Brigantine and the Imposible.

Having landed on the right bank of the Neveri, we ascended to a little fort called El Morro de Barcelona, situated at the elevation of sixty or seventy toises above the level of the sea. The Morro is a calcareous rock which has been lately fortified.

The view from the summit of the Morro is not without beauty. The rocky island of Boracha lies on the east, the lofty promontory of Unare is on the west, and below are seen the mouth of the river Neveri, and the arid shores on which the crocodiles come to sleep in the sun. Notwithstanding the extreme heat of the air, for the thermometer, exposed to the reflection of the white calcareous rock, rose to 38 degrees, we traversed the whole of the eminence. A fortunate chance led us to observe some very curious geological phenomena, which we again met with in the Cordilleras of Mexico. The limestone of Barcelona has a dull, even, or conchoidal fracture, with very flat cavities. It is divided into very thin strata, and exhibits less analogy with the limestone of Cumanacoa, than with that of Caripe, forming the cavern of the Guacharo. It is traversed by banks of schistose jasper,* (Kieselschiefer of Werner. )* black, with a conchoidal fracture, and breaking into fragments of a parallelopipedal figure. This fossil does not exhibit those little streaks of quartz so common in the Lydian stone. It is found decomposed at its surface into a yellowish grey crust, and it does not act upon the magnet. Its edges, a little translucid, give it some resemblance to the hornstone, so common in secondary limestones.* (* In Switzerland, the hornstone passing into common jasper is found in kidney-stones, and in layers both in the Alpine and Jura limestone, especially in the former.) It is remarkable that we find the schistose jasper which in Europe characterizes the transition rocks,* (The transition-limestone and schist.) in a limestone having great analogy with that of Jura. In the study of formations, which is the great end of geognosy, the knowledge acquired in the old and new worlds should be made to furnish reciprocal aid to each other. It appears that these black strata are found also in the calcareous mountains of the island of Boracha.* (* We saw some of it as ballast, in a fishing boat at Punta Araya. Its fragments might have been mistaken for basalt.) Another jasper, that known by the name of the Egyptian pebble, was found by M. Bonpland near the Indian village of Curacatiche or Curacaguitiche, fifteen leagues south of the Morro of Barcelona, when, on our return from the Orinoco, we crossed the llanos, and approached the mountains on the coast. This stone presented yellowish concentric lines and bands, on a reddish brown ground. It appeared to me that the round pieces of Egyptian jasper belonged also to the Barcelona limestone. Yet, according to M. Cordier, the fine pebbles of Suez owe their origin to a breccia formation, or siliceous agglomerate.

At the moment of our setting sail, on the 19th of November, at noon, I took some altitudes of the moon, to determine the longitude of the Morro. The difference of meridian between Cumana and the town of Barcelona, where I made a great number of astronomical observations in 1800, is 34 minutes 48 seconds. I found the dip of the needle 42.20 degrees: the intensity of the forces was equal to 224 oscillations.

From the Morro of Barcelona to Cape Codera, the land becomes low, as it recedes southward; and the soundings extend to the distance of three miles. Beyond this we find the bottom at forty-five or fifty fathoms. The temperature of the sea at its surface was 25.9 degrees; but when we were passing through the narrow channel which separates the two Piritu Islands, in three fathoms water, the thermometer was only 24.5 degrees. The difference would perhaps be greater, if the current, which runs rapidly westward, stirred up deeper water; and if, in a pass of such small width, the land did not contribute to raise the temperature of the sea. The Piritu Islands resemble those shoals which become visible when the tide falls. They do not rise more than eight or nine inches above the mean height of the sea. Their surface is smooth, and covered with grass. We might have thought we were gazing on some of our own northern meadows. The disk of the setting sun appeared like a globe of fire suspended over the savannah; and its last rays, as they swept the earth, illumined the grass, which was at the same time agitated by the evening breeze. In the low and humid parts of the equinoctial zone, even when the gramineous plants and reeds present the aspect of a meadow, a rich accessory of the picture is usually wanting; I allude to that variety of wild flowers, which, scarcely rising above the grass, seem as it were, to lie upon a smooth bed of verdure. Within the tropics, the strength and luxury of vegetation give such a development to plants, that the smallest of the dicotyledonous family become shrubs. It would seem as if the liliaceous plants, mingling with the gramina, assumed the place of the flowers of our meadows. Their form is indeed striking; they dazzle by the variety and splendour of their colours; but being too high above the soil, they disturb that harmonious proportion which characterizes the plants of our European meadows. Nature has in every zone stamped on the landscape the peculiar type of beauty proper to the locality.

We must not be surprised that fertile islands, so near Terra Firma, are not now inhabited. It was only at the early period of the discovery, and whilst the Caribbees, Chaymas, and Cumanagotos were still masters of the coast, that the Spaniards formed settlements at Cubagua and Margareta. When the natives were subdued, or driven southward in the direction of the savannahs, the preference was given to settlements on the continent, where there was a choice of land, and where there were Indians, who might be treated like beasts of burden. Had the little islands of Tortuga, Blanquilla, and Orchilla been situated in the group of the Antilles, they would not have remained without traces of cultivation.

Vessels of heavy burthen pass between the main land and the most southern of the Piritu Islands. Being very low, their northern point is dreaded by pilots who near the coast in those latitudes. When we found ourselves to westward of the Morro of Barcelona, and the mouth of the river Unare, the sea, till then calm, became agitated and rough in proportion as we approached Cape Codera. The influence of that vast promontory is felt from afar, in that part of the Caribbean Sea. The length of the passage from Cumana to La Guayra depends on the degree of ease or difficulty with which Cape Codera can be doubled. Beyond this cape the sea constantly runs so high, that we can scarcely believe we are near a coast where (from the point of Paria as far as Cape San Roman) a gale of wind is never known. On the 20th of November at sunrise we were so far advanced, that we might expect to double the cape in a few hours. We hoped to reach La Guayra the same day; but our Indian pilot being afraid of the privateers who were near that port, thought it would be prudent to make for land, and anchor in the little harbour of Higuerote, which we had already passed, and await the shelter of night to proceed on our voyage.

On the 20th of November at nine in the morning we were at anchor in the bay just mentioned, situated westward of the mouth of the Rio Capaya. We found there neither village nor farm, but merely two or three huts, inhabited by Mestizo fishermen. Their livid hue, and the meagre condition of their children, sufficed to remind us that this spot is one of the most unhealthy of the whole coast. The sea has so little depth along these shores, that even with the smallest barks it is impossible to reach the shore without wading through the water. The forests come down nearly to the beach, which is covered with thickets of mangroves, avicennias, manchineel-trees, and that species of suriana which the natives call romero de la mar.* (* Suriana maritima.) To these thickets, and particularly to the exhalations of the mangroves, the extreme insalubrity of the air is attributed here, as in other places in both Indies. On quitting the boats, and whilst we were yet fifteen or twenty toises distant from land, we perceived a faint and sickly smell, which reminded me of that diffused through the galleries of deserted mines, where the lights begin to be extinguished, and the timber is covered with flocculent byssus. The temperature of the air rose to 34 degrees, heated by the reverberation from the white sands which form a line between the mangroves and the great trees of the forest. As the shore descends with a gentle slope, small tides are sufficient alternately to cover and uncover the roots and part of the trunks of the mangroves. It is doubtless whilst the sun heats the humid wood, and causes the fermentation, as it were, of the ground, of the remains of dead leaves and of the molluscs enveloped in the drift of floating seaweed, that those deleterious gases are formed, which escape our researches. We observed that the sea-water, along the whole coast, acquired a yellowish brown tint, wherever it came into contact with the mangrove trees.

Struck with this phenomenon, I gathered at Higuerote a considerable quantity of branches and roots, for the purpose of making some experiments on the infusion of the mangrove, on my arrival at Caracas. The infusion in warm water had a brown colour and an astringent taste. It contained a mixture of extractive matter and tannin. The rhizophora, the mistletoe, the cornel-tree, in short, all the plants which belong to the natural families of the lorantheous and the caprifoliaceous plants, have the same properties. The infusion of mangrove-wood, kept in contact with atmospheric air under a glass jar for twelve days, was not sensibly deteriorated in purity. A little blackish flocculent sediment was formed, but it was attended by no sensible absorption of oxygen. The wood and roots of the mangrove placed under water were exposed to the rays of the sun. I tried to imitate the daily operations of nature on the coasts at the rise of the tide. Bubbles of air were disengaged, and at the expiration of ten days they formed a volume of thirty-three cubic inches. They were a mixture of azotic gas and carbonic acid. Nitrous gas scarcely indicated the presence of oxygen.* (* In a hundred parts there were eighty-four of nitrogen, fifteen of carbonic acid gas that the water had not absorbed, and one of oxygen.) Lastly, I set the wood and the roots of the mangrove thoroughly wetted, to act on a given volume of atmospheric air in a phial with a ground-glass stopple. The whole of the oxygen disappeared; and, far from being superseded by carbonic acid, lime-water indicated only 0.02. There was even a diminution of the volume of air, more than correspondent with the oxygen absorbed. These slight experiments led me to conclude that it is the moistened bark and wood which act upon the atmosphere in the forests of mangrove-trees, and not the water strongly tinged with yellow, forming a distinct band along the coasts. In pursuing the different stages of the decomposition of the ligneous matter, I observed no appearance of a disengagement of sulphuretted hydrogen, to which many travellers attribute the smell perceived amidst mangroves. The decomposition of the earthy and alkaline sulphates, and their transition to the state of sulphurets, may no doubt favour this disengagement in many littoral and marine plants; for instance, in the fuci: but I am rather inclined to think that the rhizophora, the avicennia, and the conocarpus, augment the insalubrity of the air by the animal matter which they contain conjointly with tannin. These shrubs belong to the three natural families of the Lorantheae, the Combretaceae, and the Pyrenaceae, in which the astringent principle abounds; this principle accompanies gelatin, even in the bark of beech, alder, and nut-trees.
