These white Guaharibos have constructed a bridge of lianas above the cataract, supported on rocks that rise, as generally happens in the pongos of the Upper Maranon, in the middle of the river. The existence of this bridge, which is known to all the inhabitants of Esmeralda,* seems to indicate that the Orinoco must be very narrow at this point. (* The Amazon also is crossed twice on bridges of wood near its source in the lake Lauricocha; first north of Chavin, and then below the confluence of the Rio Aguamiras. These, the only two bridges that have been thrown over the largest river we yet know, are called Puente de Quivilla, and Puente de Guancaybamba.) It is generally estimated by the Indians to be only two or three hundred feet broad. They say that the Orinoco, above the Raudal of the Guaharibos, is no longer a river, but a brook (riachuelo); while a well informed ecclesiastic, Fray Juan Gonzales, who had visited those countries, assured me that the Orinoco, in the part where its farther course is no longer known, is two-thirds of the breadth of the Rio Negro near San Carlos. This opinion appears to me hardly probable; but I relate what I have collected, and affirm nothing positively.

In the rocky dike that crosses the Orinoco, forming the Raudal of the Guaharibos, Spanish soldiers pretend to have found the fine kind of saussurite (Amazon-stone), of which we have spoken. This tradition however is very uncertain; and the Indians, whom I interrogated on the subject, assured me that the green stones, called piedras de Macagua* at Esmeralda, were purchased from the Guaicas and Guaharibos, who traffic with hordes much farther to the east. (* The etymology of this name, which is unknown to me, might lead to the knowledge of the spot where these stones are found. I have sought in vain the name of Macagua among the numerous tributary streams of the Tacutu, the Mahu, the Rupunury, and the Rio Trombetas.) The same uncertainty prevails respecting these stones, as that which attaches to many other valuable productions of the Indies. On the coast, at the distance of some hundred leagues, the country where they are found is positively named; but when the traveller with difficulty penetrates into that country, he discovers that the natives are ignorant even of the name of the object of his research. It might be supposed that the amulets of saussurite found in the possession of the Indians of the Rio Negro, come from the Lower Maranon, while those that are received by the missions of the Upper Orinoco and the Rio Carony come from a country situated between the sources of the Essequibo and the Rio Branco. The opinion that this stone is taken in a soft state like paste from the little lake Amucu, though very prevalent at Angostura, is wholly without foundation. A curious geognostic discovery remains to be made in the eastern part of America, that of finding in a primitive soil a rock of euphotide containing the piedra de Macagua.

I shall here proceed to give some information respecting the tribes of dwarf and fair Indians, which ancient traditions have placed near the sources of the Orinoco. I had an opportunity of seeing some of these Indians at Esmeralda, and can affirm that the short stature of the Guaicas, and the fair complexion of the Guaharibos, whom Father Caulin calls Guaribos blancos, have been alike exaggerated. The Guaicas, whom I measured, were in general from four feet seven inches to four feet eight inches high (old measure of France).* (* About five feet three inches English measure.) We were assured that the whole tribe were of this diminutive size; but we must not forget that what is called a tribe constitutes, properly speaking, but one family, owing to the exclusion of all foreign connections. The Indians of the lowest stature next to the Guaicas are the Guainares and the Poignaves. It is singular, that all these nations are found in near proximity to the Caribs, who are remarkably tall. They all inhabit the same climate, and subsist on the same aliments. They are varieties in the race, which no doubt existed previously to the settlement of these tribes (tall and short, fair and dark brown) in the same country. The four nations of the Upper Orinoco, which appeared to me to be the fairest, are the Guaharibos of the Rio Gehette, the Guainares of the Ocamo, the Guaicas of Cano Chiguire, and the Maquiritares of the sources of the Padamo, the Jao, and the Ventuari. It being very extraordinary to see natives with a fair skin beneath a burning sky, and amid nations of a very dark hue, the Spaniards have attempted to explain this phenomenon by the following hypotheses. Some assert, that the Dutch of Surinam and the Rio Essequibo may have intermingled with the Guaharibos and the Guainares; others insist, from hatred to the Capuchins of the Carony, and the Observantins of the Orinoco, that the fair Indians are what are called in Dalmatia muso di frate, children whose legitimacy is somewhat doubtful. In either case the Indios blancos would be mestizos, that is to say, children of an Indian woman and a white man. Now, having seen thousands of mestizos, I can assert that this supposition is altogether inaccurate. The individuals of the fair tribes whom we examined, have the features, the stature, and the smooth, straight, black hair which characterises other Indians. It would be impossible to take them for a mixed race, like the descendants of natives and Europeans. Some of these people are very little, others are of the ordinary stature of the copper-coloured Indians. They are neither feeble nor sickly, nor are they albinos; and they differ from the copper-coloured races only by a much less tawny skin. It would be useless, after these considerations, to insist on the distance of the mountains of the Upper Orinoco from the shores inhabited by the Dutch. I will not deny that descendants of fugitive negroes may have been seen among the Caribs, at the sources of the Essequibo; but no white man ever went from the eastern coast to the Rio Gehette and the Ocamo, in the interior of Guiana. It must also be observed, although we may be struck with the singularity of several fair tribes being found at one point to the east of Esmeralda, it is no less certain, that tribes have been found in other parts of America, distinguished from the neighbouring tribes by the less tawny colour of their skin. Such are the Arivirianos and Maquiritares of the Rio Ventuario and the Padamo, the Paudacotos and Paravenas of the Erevato, the Viras and Araguas of the Caura, the Mologagos of Brazil, and the Guayanas of the Uruguay.* (* The Cumanagotos, the Maypures, the Mapojos, and some hordes of the Tamanacs, are also fair, but in a less degree than the tribes I have just named. We may add to this list (which the researches of Sommering, Blumenbach, and Pritchard, on the varieties of the human species, have rendered so interesting) the Ojes of the Cuchivero, the Boanes (now almost destroyed) of the interior of Brazil, and in the north of America, far from the north-west coast, the Mandans and the Akanas (Walkenaer, Geogr. page 645. Gili volume 2 page 34. Vater, Amerikan. Sprachen page 81. Southey volume 1 page 603.) The most tawny, we might almost say the blackest of the American race, are the Otomacs and the Guamos. These have perhaps given rise to the confused notions of American negroes, spread through Europe in the early times of the conquest. (Herrera Dec 1 lib 3 cap 9, volume 1 page 79. Garcia, Origen de los Americanos page 259.) Who are those Negros de Quereca, placed by Gomara page 277, in that very isthmus of Panama, whence we received the first absurd tales of an albino American people? In reading with attention the authors of the beginning of the 16th century, we see that the discovery of America and of a new race of men, had singularly awakened the interest of travellers respecting the varieties of our species. Now, if a black race had been mingled with copper-colored men, as in the South-sea Islands, the conquistadores would not have failed to speak of it in a precise manner. Besides, the religious traditions of the Americans relate the appearance, in the heroic times, of white and bearded men as priests and legislators; but none of these traditions make mention of a black race.)

These phenomena are so much the more worthy of attention as they are observed in that great branch of the American nations generally ranked in a class totally opposite to that circumpolar branch, namely the Tschougaz-Esquimaux,* whose children are fair, and who acquire the Mongol or yellowish tint only from the influence of the air and the humidity. (* The Chevalier Gieseke has recently confirmed all that Krantz related of the colour of the skin of the Esquimaux. That race (even in the latitude of seventy-five and seventy-six degrees, where the climate is so rigorous) is not in general so diminutive as it was long believed to be. Ross' Voyage to the North.) In Guiana, the hordes who live in the midst of the thickest forests are generally less tawny than those who inhabit the shores of the Orinoco, and are employed in fishing. But this slight difference, which is alike found in Europe between the artisans of towns and the cultivators of the fields or the fishermen on the coasts, in no way explains the problem of the Indios blancos. They are surrounded by other Indians of the woods (Indios del monte) who are of a reddish-brown, although now exposed to the same physical influences. The causes of these phenomena are very ancient, and we may repeat with Tacitus, "est durans originis vis."

The fair-complexioned tribes, which we had an opportunity of seeing at the mission of Esmeralda, inhabit part of a mountainous country lying between the sources of six tributaries of the Orinoco; that is to say, between the Padamo, the Jao, the Ventuari, the Erevato, the Aruy, and the Paraguay.* (* They are six tributary streams on the right bank of the Orinoco; the first three run towards the south, or the Upper Orinoco; the three others towards the north, or the Lower Orinoco.) The Spanish and Portuguese missionaries are accustomed to designate this country more particularly by the name of Parima.* (* The name Parima, which signifies water, great water, is applied sometimes, and more especially, to the land washed by the Rio Parima, or Rio Branco (Rio de Aguas Blancas), a stream running into the Rio Negro; sometimes to the mountains (Sierra Parima), which divide the Upper and Lower Orinoco.) Here, as in several other countries of Spanish America, the savages have reconquered what had been wrested from them by civilization, or rather by its precursors, the missionaries. The expedition of the boundaries under Solano, and the extravagant zeal displayed by a governor of Guiana for the discovery of El Dorado, partially revived in the latter half of the eighteenth century that spirit of enterprise which characterised the Spaniards at the period of the discovery of America. In going along the Rio Padamo, a road was observed across the forests and savannahs (the length of ten days' journey), from Esmeralda to the sources of the Ventuari; and in two days more, from those sources, by the Erevato, the missions on the Rio Caura were reached. Two intelligent and enterprising men, Don Antonio Santos and Captain Bareto, had established, with the aid of the Miquiritares, a chain of military posts on this line from Esmeralda to the Rio Erevato. These posts consisted of block-houses (casas fuertes), mounted with swivels, such as I have already mentioned. The soldiers, left to themselves, exercised all kinds of vexations on the natives (Indians of peace), who had cultivated pieces of ground around the casas fuertes; and the consequence was that, in 1776, several tribes formed a league against the Spaniards. All the military posts were attacked on the same night, on a line of nearly fifty leagues in length. The houses were burnt, and many soldiers massacred; a very small number only owing their preservation to the pity of the Indian women. This nocturnal expedition is still mentioned with horror. It was concerted in the most profound secrecy, and executed with that spirit of unity which the natives of America, skilled in concealing their hostile passions, well know how to practise in whatever concerns their common interests. Since 1776 no attempt has been made to re-establish the road which leads by land from the Upper to the Lower Orinoco, and no white man has been able to pass from Esmeralda to the Erevato. It is certain, however, that in the mountainous lands, between the sources of the Padamo and the Ventuari (near the sites called by the Indians Aurichapa, Ichuana, and Irique) there are many spots where the climate is temperate, and where there are pasturages capable of feeding numerous herds of cattle. The military posts were very useful in preventing the incursions of the Caribs, who, from time to time carried off slaves, though in very small numbers, between the Erevato and the Padamo. They would have resisted the attacks of the natives, if, instead of leaving them isolated and solely to the control of the soldiery, they had been formed into communities, and governed like the villages of neophyte Indians.

We left the mission of Esmeralda on the 23rd of May. Without being positively ill, we felt ourselves in a state of languor and weakness, caused by the torment of insects, bad food, and a long voyage, in narrow and damp boats. We did not go up the Orinoco beyond the mouth of the Rio Guapo, which we should have done, if we could have attempted to reach the sources of the river. There remains a distance of fifteen leagues from the Guapo to the Raudal of the Guaharibos. At this cataract, which is passed on a bridge of lianas, Indians are posted armed with bows and arrows to prevent the whites, or those who come from their territory from advancing westward. How could we hope to pass a point where the commander of the Rio Negro, Don Francisco Bovadilla, was stopped when, accompanied by his soldiers, he tried to penetrate beyond the Gehette?* (* See above.) The carnage then made among the natives has rendered them more distrustful, and more averse to the inhabitants of the missions. It must be remembered that the Orinoco had hitherto offered to geographers two distinct problems, alike important, the situation of its sources, and the mode of its communication with the Amazon. The latter problem formed the object of the journey which I have described; with respect to the discovery of its sources, that remains to be done by the Spanish and Portuguese governments.

Our canoe was not ready to receive us till near three o'clock in the afternoon. It had been filled with innumerable swarms of ants during the navigation of the Cassiquiare; and the toldo, or roof of palm-leaves, beneath which we were again doomed to remain stretched out during twenty-two days, was with difficulty cleared of these insects. We employed part of the morning in repeating to the inhabitants of Esmeralda the questions we had already put to them, respecting the existence of a lake towards the east. We showed copies of the maps of Surville and La Cruz to old soldiers, who had been posted in the mission ever since its first establishment. They laughed at the supposed communication of the Orinoco with the Rio Idapa, and at the White Sea, which the former river was represented to cross. What we politely call geographical fictions they termed lies of the old world (mentiras de por alla). These good people could not comprehend how men, in making the map of a country which they had never visited, could pretend to know things in minute detail, of which persons who lived on the spot were ignorant. The lake Parima, the Sierra Mey, and the springs which separate at the point where they issue from the earth, were entirely unknown at Esmeralda. We were repeatedly assured that no one had ever been to the east of the Raudal of the Guaharibos; and that beyond that point, according to the opinion of some of the natives, the Orinoco descends like a small torrent from a group of mountains, inhabited by the Coroto Indians. Father Gili, who was living on the banks of the Orinoco when the expedition of the boundaries arrived, says expressly that Don Apollinario Diez was sent in 1765 to attempt the discovery of the source of the Orinoco; that he found the river, east of Esmeralda, full of shoals; that he returned for want of provision; and that he learned nothing, absolutely nothing, of the existence of a lake. This statement perfectly accords with what I heard myself thirty-five years later at Esmeralda. The probability of a fact is powerfully shaken when it can be proved to be totally unknown on the very spot where it ought to be known best; and when those by whom the existence of the lake is affirmed contradict each other, not in the least essential circumstances, but in all that are the most important.

When travellers judge only by their own sensations they differ from each other respecting the abundance of the mosquitos as they do respecting the progressive increase or diminution of the temperature. The state of our organs, the motion of the air, its degree of humidity or dryness, its electric intensity, a thousand circumstances contribute at once to make us suffer more or less from the heat and the insects. My fellow travellers were unanimously of opinion that Esmeralda was more tormented by mosquitos than the banks of the Cassiquiare, and even more than the two missions of the Great Cataracts; whilst I, less sensible than they of the high temperature of the air, thought that the irritation produced by the insects was somewhat less at Esmeralda than at the entrance of the Upper Orinoco. On hearing the complaints that are made of these tormenting insects in hot countries it is difficult to believe that their absence, or rather their sudden disappearance, could become a subject of inquietude; yet such is the fact. The inhabitants of Esmeralda related to us, that in the year 1795, an hour before sunset, when the mosquitos usually form a very thick cloud, the air was observed to be suddenly free from them. During the space of twenty minutes, not one insect was perceived, although the sky was cloudless, and no wind announced rain. It is necessary to have lived in those countries to comprehend the degree of surprise which the sudden disappearance of the insects must have produced. The inhabitants congratulated each other, and inquired whether this state of happiness, this relief from pain (feicidad y alivio), could be of any duration. But soon, instead of enjoying the present, they yielded to chimerical fears, and imagined that the order of nature was perverted. Some old Indians, the sages of the place, asserted that the disappearance of the insects must be the precursor of a great earthquake. Warm discussions arose; the least noise amid the foliage of the trees was listened to with an attentive ear; and when the air was again filled with mosquitos they were almost hailed with pleasure. We could not guess what modification of the atmosphere had caused this phenomenon, which must not be confounded with the periodical replacing of one species of insects by another.

After four hours' navigation down the Orinoco we arrived at the point of the bifurcation. Our resting place was on the same beach of the Cassiquiare, where a few days previously our great dog had, as we believe, been carried off by the jaguars. All the endeavours of the Indians to discover any traces of the animal were fruitless. The cries of the jaguars were heard during the whole night.* (* This frequency of large jaguars is somewhat remarkable in a country destitute of cattle. The tigers of the Upper Orinoco are far less bountifully supplied with prey than those of the Pampas of Buenos Ayres and the Llanos of Caracas, which are covered with herds of cattle. More than four thousand jaguars are killed annually in the Spanish colonies, several of them equalling the mean size of the royal tiger of Asia. Two thousand skins of jaguars were formerly exported annually from Buenos Ayres alone.) These animals are very frequent in the tracts situated between the Cerro Maraguaca, the Unturan, and the banks of the Pamoni. There also is found that black species of tiger* of which I saw some fine skins at Esmeralda. (* Gmelin, in his Synonyma, seems to confound this animal, under the name of Felis discolor, with the great American lion (Felis concolor) which is very different from the puma of the Andes of Quito.) This animal is celebrated for its strength and ferocity; it appears to be still larger than the common jaguar. The black spots are scarcely visible on the dark-brown ground of its skin. The Indians assert, that these tigers are very rare, that they never mingle with the common jaguars, and that they form another race. I believe that Prince Maximilian of Neuwied, who has enriched American zoology by so many important observations, acquired the same information farther to the south, in the hot part of Brazil. Albino varieties of the jaguar have been seen in Paraguay: for the spots of these animals, which may be called the beautiful panthers of America, are sometimes so pale as to be scarcely distinguishable on a very white ground. In the black jaguars, on the contrary, it is the colour of the ground which renders the spots indistinct. It requires to reside long in those countries, and to accompany the Indians of Esmeralda in the perilous chase of the tiger, to decide with certainty upon the varieties and the species. In all the mammiferae, and particularly in the numerous family of the apes, we ought, I believe, to fix our attention less on the transition from one colour to another in individuals, than on their habit of separating themselves, and forming distinct bands.

We left our resting place before sunrise on the 24th of May. In a rocky cove, which had been the dwelling of some Durimundi Indians, the aromatic odour of the plants was so powerful, that although sleeping in the open air, and the irritability of our nervous system being allayed by the habits of a life of fatigue, we were nevertheless incommoded by it. We could not ascertain the flowers which diffused this perfume. The forest was impenetrable; but M. Bonpland believed that large clumps of pancratium and other liliaceous plants were concealed in the neighbouring marshes. Descending the Orinoco by favour of the current, we passed first the mouth of the Rio Cunucunumo, and then the Guanami and the Puriname. The two banks of the principal river are entirely desert; lofty mountains rise on the north, and on the south a vast plain extends far as the eye can reach beyond the sources of the Atacavi, which lower down takes the name of the Atabapo. There is something gloomy and desolate in this aspect of a river, on which not even a fisherman's canoe is seen. Some independent tribes, the Abirianos and the Maquiritares, dwell in the mountainous country; but in the neighbouring savannahs,* bounded by the Cassiquiare, the Atabapo, the Orinoco, and the Rio Negro, there is now scarcely any trace of a human habitation. (* They form a quadrilateral plot of a thousand square leagues, the opposite sides of which have contrary slopes, the Cassiquiare flowing towards the south, the Atabapo towards the north, the Orinoco towards the north-west, and the Rio Negro towards the south-east.) I say now; for here, as in other parts of Guiana, rude figures representing the sun, the moon, and different animals, traced on the hardest rocks of granite, attest the anterior existence of a people, very different from those who became known to us on the banks of the Orinoco. According to the accounts of the natives, and of the most intelligent missionaries, these symbolic signs resemble perfectly the characters we saw a hundred leagues more to the north, near Caycara, opposite the mouth of the Rio Apure. (See Chapter 2.18 above.)

In advancing from the plains of the Cassiquiare and the Conorichite, one hundred and forty leagues further eastward, between the sources of the Rio Blanco and the Rio Essequibo, we also meet with rocks and symbolical figures. I have lately verified this curious fact, which is recorded in the journal of the traveller Hortsman, who went up the Rupunuvini, one of the tributary streams of the Essequibo. Where this river, full of small cascades, winds between the mountains of Macarana, he found, before he reached lake Amucu, rocks covered with figures, or (as he says in Portuguese) with varias letras. We must not take this word letters in its real signification. We were also shewn, near the rock Culimacari, on the banks of the Cassiquiare, and at the port of Caycara in the Lower Orinoco, traces which were believed to be regular characters. They were however only misshapen figures, representing the heavenly bodies, together with tigers, crocodiles, boas, and instruments used for making the flour of cassava. It was impossible to recognize in these painted rocks* (the name by which the natives denote those masses loaded with figures) any symmetrical arrangement, or characters with regular spaces. (* In Tamanac tepumereme. (Tepu, a stone, rock; as in Mexican, tetl, a stone, and tepetl, a mountain; in Turco-Tatarian, tepe.) The Spanish Americans also call the rock covered with sculptured figures, piedras pintadas; those for instance, which are found on the summit of the Paramo of Guanacas, in New Grenada, and which recall to mind the tepumereme of the Orinoco, the Cassiquiare, and the Rupunuvini.) The traces discovered in the mountains of Uruana, by the missionary Fray Ramon Bueno, approach nearer to alphabetical writing; but are nevertheless very doubtful.

Whatever may be the meaning of these figures, and with whatever view they were traced upon granite, they merit the examination of those who direct their attention to the philosophic history of our species. In travelling from the coast of Caracas towards the equator, we are at first led to believe that monuments of this kind are peculiar to the mountain-chain of Encaramada; they are found at the port of Sedeno, near Caycara,* (* In the Mountains of the Tyrant, Cerros del Tirano.) at San Rafael del Capuchino, opposite Cabruta, and in almost every place where the granitic rock pierces the soil, in the savannah which extends from the Cerro Curiquima towards the banks of the Caura. The nations of the Tamanac race, the ancient inhabitants of those countries, have a local mythology, and traditions connected with these sculptured rocks. Amalivaca, the father of the Tamanacs, that is, the creator of the human race (for every nation regards itself as the root of all other nations), arrived in a bark, at the time of the great inundation, which is called the age of water,* when the billows of the ocean broke against the mountains of Encaramada in the interior of the land. (* The Atonatiuh of the Mexicans, the fourth age, the fourth regeneration of the world.) All mankind, or, to speak more correctly, all the Tamanacs, were drowned, with the exception of one man and one woman, who saved themselves on a mountain near the banks of the Asiveru, called Cuchivero by the Spaniards. This mountain is the Ararat of the Aramean or Semitic nations, and the Tlaloc or Colhuacan of the Mexicans. Amalivaca, sailing in his bark, engraved the figures of the moon and the sun on the Painted Rock (Tepumereme) of Encaramada. Some blocks of granite piled upon one another, and forming a kind of cavern, are still called the house or dwelling of the great forefather of the Tamanacs. The natives show also a large stone near this cavern, in the plains of Maita, which they say was an instrument of music, the drum of Amalivaca. We must here observe, that this heroic personage had a brother, Vochi, who helped him to give the surface of the earth its present form. The Tamanacs relate that the two brothers, in their system of perfectibility, sought, at first, to arrange the Orinoco in such a manner, that the current of the water could always be followed either going down or going up the river. They hoped by this means to spare men trouble in navigating rivers; but, however great the power of these regenerators of the world, they could never contrive to give a double slope to the Orinoco, and were compelled to relinquish this singular plan. Amalivaca had daughters, who had a decided taste for travelling. The tradition states, doubtless with a figurative meaning, that he broke their legs, to render them sedentary, and force them to people the land of the Tamanacs. After having regulated everything in America, on that side of the great water, Amalivaca again embarked, and returned to the other shore, to the same place from whence he came. Since the natives have seen the missionaries arrive, they imagine that Europe is this other shore; and one of them inquired with great simplicity of Father Gili, whether he had there seen the great Amalivaca, the father of the Tamanacs, who had covered the rocks with symbolic figures.

These notions of a great convulsion of nature; of two human beings saved on the summit of a mountain, and casting behind them the fruits of the mauritia palm-tree, to repeople the earth; of that national divinity, Amalivaca, who arrived by water from a distant land, who prescribed laws to nature, and forced the nations to renounce their migrations; these various features of a very ancient system of belief, are well worthy of attention. What the Tamanacs, and the tribes whose languages are analogous to the Tamanac tongue, now relate to us, they have no doubt learned from other people, who inhabited before them the same regions. The name of Amalivaca is spread over a region of more than five thousand square leagues; he is found designated as the father of mankind, or our great grandfather, as far as to the Caribbee nations, whose idiom approaches the Tamanac only in the same degree as the German approaches the Greek, the Persian, and the Sanscrit. Amalivaca is not originally the Great Spirit, the Aged of Heaven, the invisible being, whose worship springs from that of the powers of nature, when nations rise insensibly to the consciousness of the unity of these powers; he is rather a personage of the heroic times, a man, who, coming from afar, lived in the land of the Tamanacs and the Caribs, sculptured symbolic figures upon the rocks, and disappeared by going back to the country he had previously inhabited beyond the ocean. The anthropomorphism of the divinity has two sources diametrically opposite; and this opposition seems to arise less from the various degrees of intellectual culture, than from the different dispositions of nations, some of which are more inclined to mysticism, and others more governed by the senses, and by external impressions. Sometimes man makes the divinities descend upon earth, charging them with the care of ruling nations, and giving them laws, as in the fables of the East; sometimes, as among the Greeks and other nations of the West, they are the first monarchs, priest-kings, who are stripped of what is human in their nature, to be raised to the rank of national divinities. Amalivaca was a stranger, like Manco-Capac, Bochica, and Quetzalcohuatl; those extraordinary men, who, in the alpine or civilized part of America, on the tablelands of Peru, New Grenada, and Anahuac, organized civil society, regulated the order of sacrifices, and founded religious congregations. The Mexican Quetzalcohuatl, whose descendants Montezuma* (* The second king of this name, of the race of Acamapitzin, properly called Montezuma-Ilhuicamina.) thought he recognized in the companions of Cortez, displays an additional resemblance to Amalivaca, the mythologic personage of savage America or the plains of the torrid zone. When advanced in age, the high-priest of Tula left the country of Anahuac, which he had filled with his miracles, to return to an unknown region, called Tlalpallan. When the monk Bernard de Sahagun arrived in Mexico, the same questions were put to him, as those which were addressed to Father Gili two hundred years later, in the forests of the Orinoco; he was asked whether he came from the other shore (del otro lado), from the countries to which Quetzalcohuatl had retired.

The region of sculptured rocks, or of painted stones, extends far beyond the Lower Orinoco, beyond the country (latitude 7 degrees 5 minutes to 7 degrees 40 minutes, longitude 68 degrees 50 minutes to 69 degrees 45 minutes) to which belongs what may be called the local fables of the Tamanacs. We again find these same sculptured rocks between the Cassiquiare and the Atabapo (latitude 2 degrees 5 minutes to 3 degrees 20 minutes; longitude 69 to 70 degrees); and between the sources of the Essequibo and the Rio Branco (latitude 3 degrees 50 minutes; longitude 62 degrees 32 minutes). I do not assert that these figures prove the knowledge of the use of iron, or that they denote a very advanced degree of culture; but even on the supposition that, instead of being symbolical, they are the fruits of the idleness of hunting nations, we must still admit an anterior race of men, very different from those who now inhabit the banks of the Orinoco and the Rupunuri. The more a country is destitute of remembrances of generations that are extinct, the more important it becomes to follow the least traces of what appears to be monumental. The eastern plains of North America display only those extraordinary circumvallations that remind us of the fortified camps (the pretended cities of vast extent) of the ancient and modern nomad tribes of Asia. In the oriental plains of South America, the force of vegetation, the heat of the climate, and the too lavish gifts of nature, have opposed obstacles still more powerful to the progress of human civilization. Between the Orinoco and the Amazon I heard no mention of any wall of earth, vestige of a dyke, or sepulchral tumulus; the rocks alone show us (and this through a great extent of country), rude sketches which the hand of man has traced in times unknown, and which are connected with religious traditions.

Before I quitted the wildest part of the Upper Orinoco, I thought it desirable to mention facts which are important only when they are considered in their connection with each other. All I could relate of our navigation from Esmeralda to the mouth of the Atabapo would be merely an enumeration of rivers and uninhabited places. From the 24th to the 27th of May, we slept but twice on land; our first resting-place was at the confluence of the Rio Jao, and our second below the mission of Santa Barbara, in the island of Minisi. The Orinoco being free from shoals, the Indian pilot pursued his course all night, abandoning the boat to the current of the river. Setting apart the time which we spent on the shore in preparing the rice and plantains that served us for food, we took but thirty-five hours in going from Esmeralda to Santa Barbara. The chronometer gave me for the longitude of the latter mission 70 degrees 3 minutes; we had therefore made near four miles an hour, a velocity which was partly owing to the current, and partly to the action of the oars. The Indians assert that the crocodiles do not go up the Orinoco above the mouth of the Rio Jao, and that the manatees are not even found above the cataract of Maypures.

The mission of Santa Barbara is situated a little to the west of the mouth of the Rio Ventuari, or Venituari, examined in 1800 by Father Francisco Valor. We found in this small village of one hundred and twenty inhabitants some traces of industry; but the produce of this industry is of little profit to the natives; it is reserved for the monks, or, as they say in these countries, for the church and the convent. We were assured that a great lamp of massive silver, purchased at the expense of the neophytes, is expected from Madrid. Let us hope that, after the arrival of this treasure, they will think also of clothing the Indians, of procuring for them some instruments of agriculture, and assembling their children in a school. Although there are a few oxen in the savannahs round the mission, they are rarely employed in turning the mill (trapiche), to express the juice of the sugar-cane; this is the occupation of the Indians, who work without pay here as they do everywhere when they are understood to work for the church. The pasturages at the foot of the mountains round Santa Barbara are not so rich as at Esmeralda, but superior to those at San Fernando de Atabapo. The grass is short and thick, yet the upper stratum of earth furnishes only a dry and parched granitic sand. The savannahs (far from fertile) of the banks of the Guaviare, the Meta, and the Upper Orinoco, are equally destitute of the mould which abounds in the surrounding forests, and of the thick stratum of clay, which covers the sandstone of the Llanos, or steppes of Venezuela. The small herbaceous mimosas contribute in this zone to fatten the cattle, but are very rare between the Rio Jao and the mouth of the Guaviare.

During the few hours of our stay at the mission of Santa Barbara, we obtained pretty accurate ideas respecting the Rio Ventuari, which, next to the Guaviare, appeared to me to be the most considerable tributary of the Orinoco. Its banks, heretofore occupied by the Maypures, are still peopled by a great number of independent nations. On going up by the mouth of the Ventuari, which forms a delta covered with palm-trees, you find in the east, after three days' journey, the Cumaruita and the Paru, two streams that rise at the foot of the lofty mountains of Cuneva. Higher up, on the west, lie the Mariata and the Manipiare, inhabited by the Macos and Curacicanas. The latter nation is remarkable for their active cultivation of cotton. In a hostile incursion (entrada) a large house was found containing more than thirty or forty hammocks of a very fine texture of spun cotton, cordage, and fishing implements. The natives had fled; and Father Valor informed us, that the Indians of the mission who accompanied him had set fire to the house before he could save these productions of the industry of the Curacicanas. The neophytes of Santa Barbara, who think themselves very superior to these supposed savages, appeared to me far less industrious. The Rio Manipiare, one of the principal branches of the Ventuari, approaches near its source those lofty mountains, the northern ridge of which gives birth to the Cuchivero. It is a prolongation of the chain of Baraguan; and there Father Gili places the table-land of Siamacu, of which he vaunts the temperate climate. The upper course of the Rio Ventuari, beyond the confluence of the Asisi, and the Great Raudales, is almost unknown. I was informed only that the Upper Ventuari bends so much towards the east that the ancient road from Esmeralda to the Rio Caura crosses the bed of the river. The proximity of the tributary streams of the Carony, the Caura, and the Ventuari, has facilitated for ages the access of the Caribs to the banks of the Upper Orinoco. Bands of this warlike and trading people went up from the Rio Carony, by the Paragua, to the sources of the Paruspa. A portage conducted them to the Chavarro, an eastern tributary stream of the Rio Caura; they descended with their canoes first this stream, and then the Caura itself as far as the mouth of the Erevato. After having gone up this last river south-west, and traversed vast savannahs for three days, they entered by the Manipiare into the great Rio Ventuari. I trace this road with precision not only because it was that by which the traffic of native slaves was carried on, but also to call the attention of those, who at some future day may rule the destiny of Guiana, to the high importance of this labyrinth of rivers.

It is by the four largest tributary streams, which the majestic river of the Orinoco receives on the right (the Carony, the Caura, the Padamo, and the Ventuari), that European civilization will one day penetrate into this region of forests and mountains, which has a surface of ten thousand six hundred square leagues, and which is bounded by the Orinoco on the north, the west, and the south. The Capuchins of Catalonia and the Observantins of Andalusia and Valencia, have already made settlements in the valleys of the Carony and the Caura. The tributary streams of the Lower Orinoco, being the nearest to the coast and to the cultivated region of Venezuela, were naturally the first to receive missionaries, and with them some germs of social life. Corresponding to the Carony and the Caura, which flow toward the north, are two great tributary streams of the Upper Orinoco, that send their waters toward the south; these are the Padamo and the Ventuari. No village has hitherto risen on their banks, though they offer advantages for agriculture and pasturage, which would be sought in vain in the valley of the immense river to which they are tributary. In the centre of these wild countries, where there will long be no other road than the rivers, every project of civilization should be founded on an intimate knowledge of the hydraulic features of the country, and the relative importance of the tributary streams.

In the morning of the 26th of May we left the little village of Santa Barbara, where we found several Indians of Esmeralda, who had come reluctantly, by order of the missionary, to construct for him a house of two stories. During the whole day we enjoyed the view of the fine mountains of Sipapo, which rise at a distance of more than eighteen leagues in the direction of north-north-west. The vegetation of the banks of the Orinoco is singularly varied in this part of the country; the aborescent ferns* descend from the mountains, and mingle with the palm-trees of the plain. (* The geographical distribution of these plants is extremely singular. Scarcely any are found on the eastern coast of Brazil. See the interesting work of Prince Maximilian of Neuwied, Reise nach Brasilien volume 1 page 274.) We rested that night on the island of Minisi; and, after having passed the mouths of the little rivers Quejanuma, Ubua, and Masao, we arrived, on the 27th of May, at San Fernando de Atabapo. We lodged in the same house which we had occupied a month previously, when going up the Rio Negro. We then directed our course towards the south, by the Atabapo and the Temi; we were now returning from the west, having made a long circuit by the Cassiquiare and the Upper Orinoco.

We remained only one day at San Fernando de Atabapo, although that village, adorned as it was by the pirijao palm-tree, with fruit like peaches, appeared to us a delicious abode. Tame pauxis* (* Not the ourax of Cuvier, Crax pauxi Linn., but the Crax alector.) surrounded the Indian huts; in one of which we saw a very rare monkey, which inhabits the banks of the Guaviare. This monkey is the caparro, which I have made known in my Observations on Zoology and comparative Anatomy; it forms, as Geoffroy believes, a new genus (Lagothrix) between the ateles and the alouates. The hair of this monkey is grey, like that of the marten, and extremely soft to the touch. The caparro is distinguished by a round head, and a mild and agreeable expression of countenance. I believe the missionary Gili is the only author who has made mention before me of this curious animal, around which zoologists begin to group other monkeys of Brazil. Having quitted San Fernando on the 27th of May, we arrived, by help of the rapid current of the Orinoco, in seven hours, at the mouth of the Rio Mataveni. We passed the night in the open air, under the granitic rock El Castillito, which rises in the middle of the river, and the form of which reminded us of the ruin called the Mouse-tower (Mausethurm), on the Rhine, opposite Bingen. Here, as on the banks of the Atabapo, we were struck by the sight of a small species of drosera, having exactly the appearance of the drosera of Europe.

The Orinoco had sensibly swelled during the night; and the current, strongly accelerated, bore us, in ten hours, from the mouth of the Mataveni to the Upper Great Cataract, that of Maypures, or Quituna. The distance which we passed over was thirteen leagues. We recalled to mind, with much satisfaction, the scenes where we had reposed in going up the river. We again found the Indians who had accompanied us in our herborizations; and we visited anew the fine spring that issues from a rock of stratified granite behind the house of the missionary: its temperature was not changed more than 0.3 degrees. From the mouth of the Atabapo as far as that of the Apure we seemed to be travelling as through a country which we had long inhabited. We were reduced to the same abstinence; we were stung by the same mosquitos; but the certainty of reaching in a few weeks the term of our physical sufferings kept up our spirits.

The passage of the canoe through the Great Cataract obliged us to stop two days at Maypures. Father Bernardo Zea, missionary at the Raudales, who had accompanied us to the Rio Negro, though ill, insisted on conducting us with his Indians as far as Atures. One of these Indians, Zerepe, the interpreter, who had been so unmercifully punished at the beach of Pararuma, rivetted our attention by his appearance of deep sorrow. We learned that his grief was caused by the loss of a young girl to whom he was engaged, and that he had lost her in consequence of false intelligence which had been spread respecting the direction of our journey. Zerepe, who was a native of Maypures, had been brought up in the woods by his parents, who were of the tribe of the Macos. He had brought with him to the mission a girl of twelve years of age, whom he intended to marry at our return from the Cataracts. The Indian girl was little pleased with the life of the missions, and she was told that the whites would go to the country of the Portuguese (Brazil), and would take Zerepe with them. Disappointed in her hopes, she seized a boat, and with another girl of her own age, crossed the Great Cataract, and fled al monte. The recital of this courageous adventure was the great news of the place. The affliction of Zerepe, however, was not of long duration. Born among the Christians, having travelled as far as the foot of the Rio Negro, understanding Spanish and the language of the Macos, he thought himself superior to the people of his tribe, and he no doubt soon forgot his forest love.

On the 31st of May we passed the rapids of Guahibos and Garcita. The islands which rise in the middle of the waters of the river were overspread with the purest verdure. The rains of winter had unfolded the spathes of the vadgiai palm-tree, the leaves of which rise straight toward the sky. The eye is never wearied of the view of those scenes, where the trees and rocks give the landscape that grand and severe character which we admire in the background of the pictures of Salvator Rosa. We landed before sunset on the eastern bank of the Orinoco, at the Puerto de la Expedicion, in order to visit the cavern of Ataruipe, which is the place of sepulchre of a whole nation destroyed. I shall attempt to describe this cavern, so celebrated among the natives.

We climbed with difficulty, and not without some danger, a steep rock of granite, entirely bare. It would have been almost impossible to fix the foot on its smooth and sloping surface, if large crystals of feldspar, resisting decomposition, did not stand out from the rock, and furnish points of support. Scarcely had we attained the summit of the mountain when we beheld with astonishment the singular aspect of the surrounding country. The foamy bed of the waters is filled with an archipelago of islands covered with palm-trees. Westward, on the left bank of the Orinoco, the wide-stretching savannahs of the Meta and the Casanare resembled a sea of verdure. The setting sun seemed like a globe of fire suspended over the plain, and the solitary Peak of Uniana, which appeared more lofty from being wrapped in vapours which softened its outline, all contributed to augment the majesty of the scene. Immediately below us lay a deep valley, enclosed on every side. Birds of prey and goatsuckers winged their lonely flight in this inaccessible circus. We found a pleasure in following with the eye their fleeting shadows, as they glided slowly over the flanks of the rock.

A narrow ridge led us to a neighbouring mountain, the rounded summit of which supported immense blocks of granite. These masses are more than forty or fifty feet in diameter; and their form is so perfectly spherical, that, as they appear to touch the soil only by a small number of points, it might be supposed, at the least shock of an earthquake, they would roll into the abyss. I do not remember to have seen anywhere else a similar phenomenon, amid the decompositions of granitic soils. If the balls rested on a rock of a different nature, as in the blocks of Jura, we might suppose that they had been rounded by the action of water, or thrown out by the force of an elastic fluid; but their position on the summit of a hill alike granitic, makes it more probable that they owe their origin to the progressive decomposition of the rock.

The most remote part of the valley is covered by a thick forest. In this shady and solitary spot, on the declivity of a steep mountain, the cavern of Ataruipe opens to the view. It is less a cavern than a jutting rock in which the waters have scooped a vast hollow when, in the ancient revolutions of our planet, they attained that height.* (* I saw no vein, no hole (four) filled with crystals. The decomposition of granitic rocks, and their separation into large masses, dispersed in the plains and valleys in the form of blocks and balls with concentric layers, appear to favour the enlarging of these natural excavations, which resemble real caverns.) In this tomb of a whole extinct tribe we soon counted nearly six hundred skeletons well preserved, and regularly placed. Every skeleton reposes in a sort of basket made of the petioles of the palm-tree. These baskets, which the natives call mapires, have the form of a square bag. Their size is proportioned to the age of the dead; there are some for infants cut off at the moment of their birth. We saw them from ten inches to three feet four inches long, the skeletons in them being bent together. They are all ranged near each other, and are so entire that not a rib or a phalanx is wanting. The bones have been prepared in three different manners, either whitened in the air and the sun, dyed red with anoto, or, like mummies, varnished with odoriferous resins, and enveloped in leaves of the heliconia or of the plantain-tree. The Indians informed us that the fresh corpse is placed in damp ground, that the flesh may be consumed by degrees; some months afterwards it is taken out, and the flesh remaining on the bones is scraped off with sharp stones. Several hordes in Guiana still observe this custom. Earthen vases half-baked are found near the mapires or baskets. They appear to contain the bones of the same family. The largest of these vases, or funeral urns, are five feet high, and three feet three inches long. Their colour is greenish-grey, and their oval form is pleasing to the eye. The handles are made in the shape of crocodiles or serpents; the edges are bordered with painted meanders, labyrinths, and grecques, in rows variously combined. Such designs are found in every zone among nations the farthest removed from each other, either with respect to their respective positions on the globe, or to the degree of civilization which they have attained. They still adorn the common pottery made by the inhabitants of the little mission of Maypures; they ornament the bucklers of the Otaheitans, the fishing-implements of the Esquimaux, the walls of the Mexican palace of Mitla, and the vases of ancient Greece.

We could not acquire any precise idea of the period to which the origin of the mapires and the painted vases, contained in the bone-cavern of Ataruipe, can be traced. The greater part seemed not to be more than a century old; but it may be supposed that, sheltered from all humidity under the influence of a uniform temperature, the preservation of these articles would be no less perfect if their origin dated from a period far more remote. A tradition circulates among the Guahibos, that the warlike Atures, pursued by the Caribs, escaped to the rocks that rise in the middle of the Great Cataracts; and there that nation, heretofore so numerous, became gradually extinct, as well as its language. The last families of the Atures still existed in 1767, in the time of the missionary Gili. At the period of our voyage an old parrot was shown at Maypures, of which the inhabitants said, and the fact is worthy of observation, that they did not understand what it said, because it spoke the language of the Atures.

We opened, to the great concern of our guides, several mapires, for the purpose of examining attentively the form of the skulls. They were all marked by the characteristics of the American race, with the exception of two or three, which approached indubitably to the Caucasian. In the middle of the Cataracts, in the most inaccessible spots, cases are found strengthened with iron bands, and filled with European tools, vestiges of clothes, and glass trinkets. These articles, which have given rise to the most absurd reports of treasures hidden by the Jesuits, probably belonged to Portuguese traders who had penetrated into these savage countries. May we suppose that the skulls of European race, which we saw mingled with the skeletons of the natives, and preserved with the same care, were the remains of some Portuguese travellers who had died of sickness, or had been killed in battle? The aversion evinced by the natives for whatever is not of their own race renders this hypothesis little probable. Perhaps fugitive mestizos of the missions of the Meta and Apure may have come and settled near the Cataracts, marrying women of the tribe of the Atures. Such mixed marriages sometimes take place in this zone, though they are more rare than in Canada, and in the whole of North America, where hunters of European origin unite themselves with savages, assume their habits, and sometimes acquire great political influence.

We took several skulls, the skeleton of a child of six or seven years old, and two of full-grown men of the nation of the Atures, from the cavern of Ataruipe. All these bones, partly painted red, partly varnished with odoriferous resins, were placed in the baskets (mapires or canastos) which we have just described. They made almost the whole load of a mule; and as we knew the superstitious feelings of the Indians in reference to the remains of the dead after burial, we carefully enveloped the canastos in mats recently woven. Unfortunately for us, the penetration of the Indians, and the extreme quickness of their sense of smelling, rendered all our precautions useless. Wherever we stopped, in the missions of the Caribbees, amid the Llanos, between Angostura and Nueva Barcelona, the natives assembled round our mules to admire the monkeys which we had purchased at the Orinoco. These good people had scarcely touched our baggage, when they announced the approaching death of the beast of burden that carried the dead. In vain we told them that they were deceived in their conjectures; and that the baskets contained the bones of crocodiles and manatees; they persisted in repeating that they smelt the resin that surrounded the skeletons, and that they were their old relations. We were obliged to request that the monks would interpose their authority, to overcome the aversion of the natives, and procure for us a change of mules.

One of the skulls, which we took from the cavern of Ataruipe, has appeared in the fine work published by my old master, Blumenbach, on the varieties of the human species. The skeletons of the Indians were lost on the coast of Africa, together with a considerable part of our collections, in a shipwreck, in which perished our friend and fellow-traveller, Fray Juan Gonzales, the young monk of the order of Saint Francis.

We withdrew in silence from the cavern of Ataruipe. It was one of those calm and serene nights which are so common in the torrid zone. The stars shone with a mild and planetary light. Their scintillation was scarcely sensible at the horizon, which seemed illumined by the great nebulae of the southern hemisphere. An innumerable multitude of insects spread a reddish light upon the ground, loaded with plants, and resplendent with these living and moving fires, as if the stars of the firmament had sunk down on the savannah. On quitting the cavern we stopped several times to admire the beauty of this singular scene. The odoriferous vanilla and festoons of bignonia decorated the entrance; and above, on the summit of the hill, the arrowy branches of the palm-trees waved murmuring in the air. We descended towards the river, to take the road to the mission, where we arrived late in the night. Our imagination was struck by all we had just seen. Occupied continually by the present, in a country where the traveller is tempted to regard human society as a new institution, he is more powerfully interested by remembrances of times past. These remembrances were not indeed of a distant date; but in all that is monumental antiquity is a relative idea, and we easily confound what is ancient with what is obscure and problematic. The Egyptians considered the historical remembrances of the Greeks as very recent. If the Chinese, or, as they prefer calling themselves, the inhabitants of the Celestial Empire, could have communicated with the priests of Heliopolis, they would have smiled at those pretensions of the Egyptians to antiquity. Contrasts not less striking are found in the north of Europe and of Asia, in the New World, and in every region where the human race has not preserved a long consciousness of itself. The migration of the Toltecs, the most ancient historical event on the tableland of Mexico, dates only in the sixth century of our era. The introduction of a good system of intercalation, and the reform of the calendars, the indispensable basis of an accurate chronology, took place in the year 1091. These epochs, which to us appear so modern, fall on fabulous times, when we reflect on the history of our species between the banks of the Orinoco and the Amazon. We there see symbolic figures sculptured on the rocks, but no tradition throws light upon their origin. In the hot part of Guiana we can go back only to the period when the Castilian and Portuguese conquerors, and more recently peaceful monks, penetrated amid so many barbarous nations.

It appears that to the north of the Cataracts, in the strait of Baraguan, there are caverns filled with bones, similar to those I have just described: but I was informed of this fact only after my return; our Indian pilots did not mention it when we landed at the strait. These tombs no doubt have given rise to a fable of the Ottomacs, according to which the granitic and solitary rocks of Baraguan, the forms of which are very singular, are regarded as the grandfathers, the ancient chiefs of the tribe. The custom of separating the flesh from the bones, very anciently practised by the Massagetes, is still known among several hordes of the Orinoco. It is even asserted, and with some probability, that the Guaraons plunge their dead bodies under water enveloped in nets; and that the small caribe-fishes, of which we saw everywhere an innumerable quantity, devour in a few days the muscular flesh, and thus prepare the skeleton. It may be supposed that this operation can be practised only in places where crocodiles are not common. Some tribes, for instance the Tamanacs, are accustomed to lay waste the fields of a deceased relative, and cut down the trees which he has planted. They say that the sight of objects which belonged to their relation makes them melancholy. They like better to efface than to preserve remembrances. These effects of Indian sensibility are very detrimental to agriculture, and the monks oppose with energy these superstitious practices, to which the natives converted to Christianity still adhere in the missions.

The tombs of the Indians of the Orinoco have not been very closely examined, because they do not contain valuable articles like those of Peru; and even on the spot no faith is now lent to the chimerical ideas, which were heretofore formed of the wealth of the ancient inhabitants of El Dorado. The thirst of gold everywhere precedes the desire of instruction, and a taste for researches into antiquity; in all the mountainous part of South America, from Merida and Santa Martha to the table-lands of Quito and Upper Peru, the labours of absolute mining have been undertaken to discover tombs, or, as the Creoles say, employing a word altered from the Inca language, guacas. When in Peru, at Mancichi, I went into the guaca from which, in the sixteenth century, masses of gold of great value were extracted. No trace of the precious metals has been found in the caverns which have served the natives of Guiana for ages as sepulchres. This circumstance proves that even at the period when the Caribs, and other travelling nations, made incursions to the south-west, gold had flowed in very small quantities from the mountains of Peru towards the eastern plains.

Wherever the granitic rocks do not present any of those large cavities caused by their decomposition, or by an accumulation of their blocks, the Indians deposit their dead in the earth. The hammock (chinchorro), a kind of net in which the deceased had reposed during his life, serves for a coffin. This net is fastened tight round the body, a hole is dug in the hut, and there the body is laid. This is the most usual method, according to the account of the missionary Gili, and it accords with what I myself learned from Father Zea. I do not believe that there exists one tumulus in Guiana, not even in the plains of the Cassiquiare and the Essequibo. Some, however, are to be met with in the savannahs of Varinas, as in Canada, to the west of the Alleghenies.* (* Mummies and skeletons contained in baskets were recently discovered in a cavern in the United States. It is believed they belong to a race of men analogous to that of the Sandwich Islands. The description of these tombs has some similitude with that of the tombs of Ataruipe.) It seems remarkable enough that, notwithstanding the extreme abundance of wood in those countries, the natives of the Orinoco were as little accustomed as the ancient Scythians to burn the dead. Sometimes they formed funeral piles for that purpose; but only after a battle, when the number of the dead was considerable. In 1748, the Parecas burned not only the bodies of their enemies, the Tamanacs, but also those of their own people who fell on the field of battle. The Indians of South America, like all nations in a state of nature, are strongly attached to the spots where the bones of their fathers repose. This feeling, which a great writer has beautifully painted in the episode of Atala, is cherished in all its primitive ardour by the Chinese. These people among whom everything is the produce of art, or rather of the most ancient civilization, do not change their dwelling without carrying along with them the bones of their ancestors. Coffins are seen deposited on the banks of great rivers, to be transported, with the furniture of the family, to a remote province. These removals of bones, heretofore more common among the savages of North America, are not practised among the tribes of Guiana; but these are not nomad, like nations who live exclusively by hunting.

We stayed at the mission of Atures only during the time necessary for passing the canoe through the Great Cataract. The bottom of our frail bark had become so thin that it required great care to prevent it from splitting. We took leave of the missionary, Bernardo Zea, who remained at Atures, after having accompanied us during two months, and shared all our sufferings. This poor monk still continued to have fits of tertian ague; they had become to him an habitual evil, to which he paid little attention. Other fevers of a more fatal kind prevailed at Atures on our second visit. The greater part of the Indians could not leave their hammocks, and we were obliged to send in search of cassava-bread, the most indispensable food of the country, to the independent but neighbouring tribe of the Piraoas. We had hitherto escaped these malignant fevers, which I believe to be always contagious.

We ventured to pass in our canoe through the latter half of the Raudal of Atures. We landed here and there, to climb upon the rocks, which like narrow dikes joined the islands to one another. Sometimes the waters force their way over the dikes, sometimes they fall within them with a hollow noise. A considerable portion of the Orinoco was dry, because the river had found an issue by subterraneous caverns. In these solitary haunts the rock-manakin with gilded plumage (Pipra rupicola), one of the most beautiful birds of the tropics, builds its nest. The Raudalito of Carucari is caused by an accumulation of enormous blocks of granite, several of which are spheroids of five or six feet in diameter, and they are piled together in such a manner, as to form spacious caverns. We entered one of these caverns to gather the confervas that were spread over the clefts and humid sides of the rock. This spot displayed one of the most extraordinary scenes of nature that we had contemplated on the banks of the Orinoco. The river rolled its waters turbulently over our heads. It seemed like the sea dashing against reefs of rocks; but at the entrance of the cavern we could remain dry beneath a large sheet of water that precipitated itself in an arch from above the barrier. In other cavities, deeper, but less spacious, the rock was pierced by the effect of successive filtrations. We saw columns of water, eight or nine inches broad, descending from the top of the vault, and finding an issue by clefts, that seemed to communicate at great distances with each other.

The cascades of Europe, forming only one fall, or several falls close to each other, can never produce such variety in the shifting landscape. This variety is peculiar to rapids, to a succession of small cataracts several miles in length, to rivers that force their way across rocky dikes and accumulated blocks of granite. We had the opportunity of viewing this extraordinary sight longer than we wished. Our boat was to coast the eastern bank of a narrow island, and to take us in again after a long circuit. We passed an hour and a half in vain expectation of it. Night approached, and with it a tremendous storm. It rained with violence. We began to fear that our frail bark had been wrecked against the rocks, and that the Indians, conformably to their habitual indifference for the evils of others, had returned tranquilly to the mission. There were only three of us: we were completely wet, and uneasy respecting the fate of our boat: it appeared far from agreeable to pass, without sleep, a long night of the torrid zone amid the noise of the Raudales. M. Bonpland proposed to leave me in the island with Don Nicolas Soto, and to swim across the branches of the river that are separated by the granitic dikes. He hoped to reach the forest, and seek assistance at Atures from Father Zea. We dissuaded him with difficulty from undertaking this hazardous enterprise. He knew little of the labyrinth of small channels, into which the Orinoco is divided. Most of them have strong whirlpools, and what passed before our eyes while we were deliberating on our situation, proved sufficiently that the natives had deceived us respecting the absence of crocodiles in the cataracts. The little monkeys which we had carried along with us for months were deposited on the point of our island. Wet by the rains and sensible of the least lowering of the temperature, these delicate animals sent forth plaintive cries, and attracted to the spot two crocodiles, the size and leaden colour of which denoted their great age. Their unexpected appearance made us reflect on the danger we had incurred by bathing, at our first passing by the mission of Atures, in the middle of the Raudal. After long waiting, the Indians at length arrived at the close of day. The natural coffer-dam by which they had endeavoured to descend in order to make the circuit of the island, had become impassable owing to the shallowness of the water. The pilot sought long for a more accessible passage in this labyrinth of rocks and islands. Happily our canoe was not damaged and in less than half an hour our instruments, provision, and animals, were embarked.

We pursued our course during a part of the night, to pitch our tent again in the island of Panumana. We recognized with pleasure the spots where we had botanized when going up the Orinoco. We examined once more on the beach of Guachaco that small formation of sandstone, which reposes directly on granite. Its position is the same as that of the sandstone which Burckhardt observed at the entrance of Nubia, superimposed on the granite of Syene. We passed, without visiting it, the new mission of San Borga, where (as we learned with regret a few days after) the little colony of Guahibos had fled al monte, from the chimerical fear that we should carry them off; to sell them as poitos, or slaves. After having passed the rapids of Tabaje, and the Raudal of Cariven, near the mouth of the great Rio Meta, we arrived without accident at Carichana. The missionary received us with that kind hospitality which he extended to us on our first passage. The sky was unfavourable for astronomical observations; we had obtained some new ones in the two Great Cataracts; but thence, as far as the mouth of the Apure, we were obliged to renounce the attempt. M. Bonpland had the satisfaction at Carichana of dissecting a manatee more than nine feet long. It was a female, and the flesh appeared to us not unsavoury. I have spoken in another place of the manner of catching this herbivorous cetacea. The Piraoas, some families of whom inhabit the mission of Carichana, detest this animal to such a degree, that they hid themselves, to avoid being obliged to touch it, whilst it was being conveyed to our hut. They said that the people of their tribe die infallibly when they eat of it. This prejudice is the more singular, as the neighbours of the Piraoas, the Guamos and the Ottomacs, are very fond of the flesh of the manatee. The flesh of the crocodile is also an object of horror to some tribes, and of predilection to others.

The island of Cuba furnishes a fact little known in the history of the manatee. South of the port of Xagua, several miles from the coast, there are springs of fresh water in the middle of the sea. They are supposed to be owing to a hydrostatic pressure existing in subterraneous channels, communicating with the lofty mountains of Trinidad. Small vessels sometimes take in water there; and, what is well worthy of observation, large manatees remain habitually in those spots. I have already called the attention of naturalists to the crocodiles which advance from the mouth of rivers far into the sea. Analogous circumstances may have caused, in the ancient catastrophes of our planet, that singular mixture of pelagian and fluviatile bones and petrifactions, which is observed in some rocks of recent formation.

Our stay at Carichana was very useful in recruiting our strength after our fatigues. M. Bonpland bore with him the germs of a cruel malady; he needed repose; but as the delta of the tributary streams included between the Horeda and Paruasi is covered with a rich vegetation, he made long herbalizations, and was wet through several times in a day. We found, fortunately, in the house of the missionary, the most attentive care; we were supplied with bread made of maize flour, and even with milk. The cows yield milk plentifully enough in the lower regions of the torrid zone, wherever good pasturage is found. I call attention to this fact, because local circumstances have spread through the Indian Archipelago the prejudice of considering hot climates as repugnant to the secretion of milk. We may conceive the indifference of the inhabitants of the New World for a milk diet, the country having been originally destitute of animals capable of furnishing it*; (* The reindeer are not domesticated in Greenland as they are in Lapland; and the Esquimaux care little for their milk. The bisons taken very young accustom themselves, on the west of the Alleghenies, to graze with herds of European cows. The females in some districts of India yield a little milk, but the natives have never thought of milking them. What is the origin of that fabulous story related by Gomara (chapter 43 page 36) according to which the first Spanish navigators saw, on the coast of South Carolina, stags led to the savannahs by herdsmen? The female bisons, according to Mr. Buchanan and the philosophical historian of the Indian Archipelago, Mr. Crawford, yield more milk than common cows.) but how can we avoid being astonished at this indifference in the immense Chinese population, living in great part beyond the tropics, and in the same latitude with the nomad and pastoral tribes of central Asia? If the Chinese have ever been a pastoral people, how have they lost the tastes and habits so intimately connected with that state, which precedes agricultural institutions? These questions are interesting with respect both to the history of the nations of oriental Asia, and to the ancient communications that are supposed to have existed between that part of the world and the north of Mexico.

We went down the Orinoco in two days, from Carichana to the mission of Uruana, after having again passed the celebrated strait of Baraguan. We stopped several times to determine the velocity of the river, and its temperature at the surface, which was 27.4 degrees. The velocity was found to be two feet in a second (sixty-two toises in 3 minutes 6 seconds) in places where the bed of the Orinoco was more than twelve thousand feet broad, and from ten to twelve fathoms deep. The slope of the river is in fact extremely gentle from the Great Cataracts to Angostura; and, if a barometric measurement were wanting, the difference of height might be determined by approximation, by measuring from time to time the velocity of the stream, and the extent of the section in breadth and depth. We had some observations of the stars at Uruana. I found the latitude of the mission to be 7 degrees 8 minutes; but the results from different stars left a doubt of more than 1 minute. The stratum of mosquitos, which hovered over the ground, was so thick that I could not succeed in rectifying properly the artificial horizon. I tormented myself in vain; and regretted that I was not provided with a mercurial horizon. On the 7th of June, good absolute altitudes of the sun gave me 69 degrees 40 minutes for the longitude. We had advanced from Esmeralda 1 degree 17 minutes toward the west, and this chronometric determination merits entire confidence on account of the double observations, made in going and returning, at the Great Cataracts, and at the confluence of the Atabapo and of the Apure.

The situation of the mission of Uruana is extremely picturesque. The little Indian village stands at the foot of a lofty granitic mountain. Rocks everywhere appear in the form of pillars above the forest, rising higher than the tops of the tallest trees. The aspect of the Orinoco is nowhere more majestic than when viewed from the hut of the missionary, Fray Ramon Bueno. It is more than two thousand six hundred toises broad, and it runs without any winding, like a vast canal, straight toward the east. Two long and narrow islands (Isla de Uruana and Isla vieja de la Manteca) contribute to give extent to the bed of the river; the two banks are parallel, and we cannot call it divided into different branches. The mission is inhabited by the Ottomacs, a tribe in the rudest state, and presenting one of the most extraordinary physiological phenomena. They eat earth; that is, they swallow every day, during several months, very considerable quantities, to appease hunger, and this practice does not appear to have any injurious effect on their health. Though we could stay only one day at Uruana, this short space of time sufficed to make us acquainted with the preparation of the poya, or balls of earth. I also found some traces of this vitiated appetite among the Guamos; and between the confluence of the Meta and the Apure, where everybody speaks of dirt-eating as of a thing anciently known. I shall here confine myself to an account of what we ourselves saw or heard from the missionary, who had been doomed to live for twelve years among the savage and turbulent tribe of the Ottomacs.

The inhabitants of Uruana belong to those nations of the savannahs called wandering Indians (Indios andantes) who, more difficult to civilize than the nations of the forest (Indios del monte), have a decided aversion to cultivate the land, and live almost exclusively by hunting and fishing. They are men of very robust constitution; but ill-looking, savage, vindictive, and passionately fond of fermented liquors. They are omnivorous animals in the highest degree; and therefore the other Indians, who consider them as barbarians, have a common saying, nothing is so loathsome but that an Ottomac will eat it. While the waters of the Orinoco and its tributary streams are low, the Ottomacs subsist on fish and turtles. The former they kill with surprising dexterity, by shooting them with an arrow when they appear at the surface of the water. When the rivers swell fishing almost entirely ceases.* (* In South America, as in Egypt and Nubia, the swelling of the rivers, which occurs periodically in every part of the torrid zone, is erroneously attributed to the melting of the snows.) It is then very difficult to procure fish, which often fails the poor missionaries, on fast-days as well as flesh-days, though all the young Indians are under the obligation of fishing for the convent. During the period of these inundations, which last two or three months, the Ottomacs swallow a prodigious quantity of earth. We found heaps of earth-balls in their huts, piled up in pyramids three or four feet high. These balls were five or six inches in diameter. The earth which the Ottomacs eat is a very fine and unctuous clay of a yellowish grey colour; and, when being slightly baked at the fire, the hardened crust has a tint inclining to red, owing to the oxide of iron which is mingled with it. We brought away some of this earth, which we took from the winter-provision of the Indians; and it is a mistake to suppose that it is steatitic, and that it contains magnesia. Vauquelin did not discover any traces of that substance in it but he found that it contained more silex than alumina, and three or four per cent of lime.

The Ottomacs do not eat every kind of clay indifferently; they choose the alluvial beds or strata, which contain the most unctuous earth, and the smoothest to the touch. I inquired of the missionary whether the moistened clay were made to undergo that peculiar decomposition which is indicated by a disengagement of carbonic acid and sulphuretted hydrogen, and which is designated in every language by the term of putrefaction; but he assured us that the natives neither cause the clay to rot, nor do they mingle it with flour of maize, oil of turtle's eggs, or fat of the crocodile. We ourselves examined, both at the Orinoco and after our return to Paris, the balls of earth which we brought away with us, and found no trace of the mixture of any organic substance, whether oily or farinaceous. The savage regards every thing as nourishing that appeases hunger: when, therefore, you inquire of an Ottomac on what he subsists during the two months when the river is at its highest flood he shows you his balls of clayey earth. This he calls his principal food at the period when he can seldom procure a lizard, a root of fern, or a dead fish swimming at the surface of the water. If necessity force the Indians to eat earth during two months (and from three quarters to five quarters of a pound in twenty-four hours), he eats it from choice during the rest of the year. Every day in the season of drought, when fishing is most abundant, he scrapes his balls of poya, and mingles a little clay with his other aliment. It is most surprising that the Ottomacs do not become lean by swallowing such quantities of earth: they are, on the contrary, extremely robust. The missionary Fray Ramon Bueno asserts that he never remarked any alteration in the health of the natives at the period of the great risings of the Orinoco.

The Ottomacs during some months eat daily three-quarters of a pound of clay slightly hardened by fire, but which they moisten before swallowing it. It has not been possible to verify hitherto with precision how much nutritious vegetable or animal matter they take in a week at the same time; but they attribute the sensation of satiety which they feel to the clay, and not to the wretched aliments which they take with it occasionally.

No physiological phenomenon being entirely insulated, it may be interesting to examine several analogous phenomena, which I have been able to collect. I observed everywhere within the torrid zone, in a great number of individuals, children, women, and sometimes even full-grown men, an inordinate and almost irresistible desire of swallowing earth; not an alkaline or calcareous earth to neutralize (as it is said) acid juices, but a fat clay, unctuous, and exhaling a strong smell. It is often found necessary to tie the children's hands or to confine them to prevent them eating earth when the rain ceases to fall. At the village of Banco, on the bank of the river Magdalena, I saw the Indian women who make pottery continually swallowing great pieces of clay. These women were not in a state of pregnancy; and they affirmed that earth is an aliment which they do not find hurtful. In other American tribes, people soon fall sick, and waste away, when they yield too much to this mania of eating earth. We found at the mission of San Borja an Indian child of the Guahiba nation, who was as thin as a skeleton. The mother informed us that the little girl was reduced to this lamentable state of atrophy in consequence of a disordered appetite, she having refused during four months to take almost any other food than clay. Yet San Borja is only twenty-five leagues distant from the mission of Uruana, inhabited by that tribe of the Ottomacs, who, from the effect no doubt of a habit progressively acquired, swallow the poya without experiencing any pernicious effects. Father Gumilla asserts that the Ottomacs take as an aperient, oil, or rather the melted fat of the crocodile, when they feel any gastric obstructions; but the missionary whom we found among them was little disposed to confirm this assertion. It may be asked, why the mania of eating earth is much more rare in the frigid and temperate than in the torrid zones; and why in Europe it is found only among women in a state of pregnancy, and sickly children. This difference between hot and temperate climates arises perhaps only from the inert state of the functions of the stomach caused by strong cutaneous perspiration. It has been supposed to be observed that the inordinate taste for eating earth augments among the African slaves, and becomes more pernicious when they are restricted to a regimen purely vegetable and deprived of spirituous liquors.

The negroes on the coast of Guinea delight in eating a yellowish earth, which they call caouac. The slaves who are taken to America endeavour to indulge in this habit; but it proves detrimental to their health. They say that the earth of the West Indies is not so easy of digestion as that of their country. Thibaut de Chanvalon, in his Voyage to Martinico, expresses himself very judiciously on this pathological phenomenon. "Another cause," he says, "of this pain in the stomach is that several of the negroes, who come from the coast of Guinea, eat earth; not from a depraved taste, or in consequence of disease, but from a habit contracted at home in Africa, where they eat, they say, a particular earth, the taste of which they find agreeable, without suffering any inconvenience. They seek in our islands for the earth most similar to this, and prefer a yellowish red volcanic tufa. It is sold secretly in our public markets; but this is an abuse which the police ought to correct. The negroes who have this habit are so fond of caouac, that no chastisement will prevent their eating it."

In the Indian Archipelago, at the island of Java, Labillardiere saw, between Surabaya and Samarang, little square and reddish cakes exposed for sale. These cakes called tanaampo, were cakes of clay, slightly baked, which the natives eat with relish. The attention of physiologists, since my return from the Orinoco, having been powerfully directed to these phenomena of geophagy, M. Leschenault (one of the naturalists of the expedition to the Antarctic regions under the command of captain Baudin) has published some curious details on the tanaampo, or ampo, of the Javanese. "The reddish and somewhat ferruginous clay," he says "which the inhabitants of Java are fond of eating occasionally, is spread on a plate of iron, and baked, after having been rolled into little cylinders in the form of the bark of cinnamon. In this state it takes the name of ampo, and is sold in the public markets. This clay has a peculiar taste, which is owing to the baking: it is very absorbent, and adheres to the tongue, which it dries. In general it is only the Javanese women who eat the ampo, either in the time of pregnancy, or in order to grow thin; the absence of plumpness being there regarded as a kind of beauty. The use of this earth is fatal to health; the women lose their appetite imperceptibly, and take only with relish a very small quantity of food; but the desire of becoming thin, and of preserving a slender shape, induces them to brave these dangers, and maintains the credit of the ampo." The savage inhabitants of New Caledonia also, to appease their hunger in times of scarcity, eat great pieces of a friable Lapis ollaris. Vauquelin analysed this stone, and found in it, beside magnesia and silex in equal portions, a small quantity of oxide of copper. M. Goldberry had seen the negroes in Africa, in the islands of Bunck and Los Idolos, eat an earth of which he had himself eaten, without being incommoded by it, and which also was a white and friable steatite. These examples of earth-eating in the torrid zone appear very strange. We are struck by the anomaly of finding a taste, which might seem to belong only to the inhabitants of the most sterile regions, prevailing among races of rude and indolent men, who live in the finest and most fertile countries on the globe. We saw at Popayan, and in several mountainous parts of Peru, lime reduced to a very fine powder, sold in the public markets to the natives among other articles of food. This powder, when eaten, is mingled with coca, that is, with the leaves of the Erythroxylon peruvianum. It is well known that Indian messengers take no other aliment for whole days than lime and coca: both excite the secretion of saliva, and of the gastric juice; they take away the appetite, without affording any nourishment to the body. In other parts of South America, on the coast of Rio de la Hacha, the Guajiros swallow lime alone, without adding any vegetable matter to it. They carry with them a little box filled with lime, as we do snuff-boxes, and as in Asia people carry a betel-box. This American custom excited the curiosity of the first Spanish navigators. Lime blackens the teeth; and in the Indian Archipelago, as among several American hordes, to blacken the teeth is to beautify them. In the cold regions of the kingdom of Quito, the natives of Tigua eat habitually from choice, and without any injurious consequences, a very fine clay, mixed with quartzose sand. This clay, suspended in water, renders it milky. We find in their huts large vessels filled with this water, which serves as a beverage, and which the Indians call agua or leche de llanka.* (* Water or milk of clay. Llanka is a word of the general language of the Incas, signifying fine clay.)

When we reflect on these facts, we perceive that the appetite for clayey, magnesian, and calcareous earth is most common among the people of the torrid zone; that it is not always a cause of disease; and that some tribes eat earth from choice, whilst others (as the Ottomacs in America, and the inhabitants of New Caledonia in the Pacific) eat it from want and to appease hunger. A great number of physiological phenomena prove that a temporary cessation of hunger may be produced though the substances that are submitted to the organs of digestion may not be, properly speaking, nutritive. The earth of the Ottomacs, composed of alumine and silex, furnishes probably nothing, or almost nothing, to the composition of the organs of man. These organs contain lime and magnesia in the bones, in the lymph of the thoracic duct, in the colouring matter of the blood, and in white hairs; they afford very small quantities of silex in black hair; and, according to Vauquelin, but a few atoms of alumine in the bones, though this is contained abundantly in the greater part of those vegetable substances which form part of our nourishment. It is not the same with man as with animated beings placed lower in the scale of organization. In the former, assimilation is exerted only on those substances that enter essentially into the composition of the bones, the muscles, and the medullary matter of the nerves and the brain. Plants, on the contrary, draw from the soil the salts that are found accidentally mixed in it; and their fibrous texture varies according to the nature of the earths that predominate in the spots which they inhabit. An object well worthy of research, and which has long fixed my attention, is the small number of simple substances (earthy and metallic) that enter into the composition of animated beings, and which alone appear fitted to maintain what we may call the chemical movement of vitality.

We must not confound the sensations of hunger with that vague feeling of debility which is produced by want of nutrition, and by other pathologic causes. The sensation of hunger ceases long before digestion takes place, or the chyme is converted into chyle. It ceases either by a nervous and tonic impression exerted by the aliments on the coats of the stomach; or, because the digestive apparatus is filled with substances that excite the mucous membranes to an abundant secretion of the gastric juice. To this tonic impression on the nerves of the stomach the prompt and salutary effects of what are called nutritive medicaments may be attributed, such as chocolate, and every substance that gently stimulates and nourishes at the same time. It is the absence of a nervous stimulant that renders the solitary use of a nutritive substance (as starch, gum, or sugar) less favourable to assimilation, and to the reparation of the losses which the human body undergoes. Opium, which is not nutritive, is employed with success in Asia, in times of great scarcity; it acts as a tonic. But when the matter which fills the stomach can be regarded neither as an aliment, that is, as proper to be assimilated, nor as a tonic stimulating the nerves, the cessation of hunger is probably owing only to the secretion of the gastric juice. We here touch upon a problem of physiology which has not been sufficiently investigated. Hunger is appeased, the painful feeling of inanition ceases, when the stomach is filled. It is said that this viscus stands in need of ballast; and every language furnishes figurative expressions which convey the idea that a mechanical distension of the stomach causes an agreeable sensation. Recent works of physiology still speak of the painful contraction which the stomach experiences during hunger, the friction of its sides against one another, and the action of the gastric juice on the texture of the digestive apparatus. The observations of Bichat, and more particularly the fine experiments of Majendie, are in contradiction to these superannuated hypotheses. After twenty-four, forty-eight, or even sixty hours of abstinence, no contraction of the stomach is observed; it is only on the fourth or fifth day that this organ appears to change in a small degree its dimensions. The quantity of the gastric juice diminishes with the duration of abstinence. It is probable that this juice, far from accumulating, is digested as an alimentary substance. If a cat or dog be made to swallow a substance which is not susceptible of being digested, a pebble for instance, a mucous and acid liquid is formed abundantly in the cavity of the stomach, somewhat resembling in its composition the gastric juice of the human body. It appears to me very probable, that when the want of aliments compels the Ottomacs and the inhabitants of New Caledonia to swallow clay and steatite during a part of the year, these earths occasion a powerful secretion of the gastric and pancreatic juices in the digestive apparatus of these people. The observations which I made on the banks of the Orinoco, have been recently confirmed by the direct experiments of two distinguished young physiologists, MM. Cloquet and Breschet. After long fasting they ate as much as five ounces of a silvery green and very flexible laminar talc. Their hunger was completely satisfied, and they felt no inconvenience from a kind of food to which their organs were unaccustomed. It is known that great use is still made in the East of the bolar and sigillated earths of Lemnos, which are clay mingled with oxide of iron. In Germany the workmen employed in the quarries of sandstone worked at the mountain of Kiffhauser spread a very fine clay upon their bread, instead of butter, which they call steinbutter* (stone-butter). (* This steinbutter must not be confounded with the mountain butter (bergbutter) which is a saline substance, produced by a decomposition of aluminous schists.)

The state of perfect health enjoyed by the Ottomacs during the time when they use little muscular exercise, and are subjected to so extraordinary a regimen, is a phenomenon difficult to be explained. It can be attributed only to a habit prolonged from generation to generation. The structure of the digestive apparatus differs much in animals that feed exclusively on flesh or on seeds; it is even probable that the gastric juice changes its nature, according as it is employed in effecting the digestion of animal or vegetable substances; yet we are able gradually to change the regimen of herbivorous and carnivorous animals, to feed the former with flesh, and the latter with vegetables. Man can accustom himself to an extraordinary abstinence and find it but little painful if he employ tonic or stimulating substances (various drugs, small quantities of opium, betel, tobacco, or leaves of coca); or if he supply his stomach, from time to time, with earthy insipid substances that are not in themselves fit for nutrition. Like man in a savage state some animals, when pressed by hunger in winter, swallow clay or friable steatites; such are the wolves in the northeast of Europe, the reindeer and, according to the testimony of M. Patrin, the kids in Siberia. The Russian hunters, on the banks of the Yenisei and the Amour, use a clayey matter which they call rock-butter, as a bait. The animals scent this clay from afar, and are fond of the smell; as the clays of bucaro, known in Portugal and Spain by the name of odoriferous earths (tierras olorosas), have an odour agreeable to women.* (* Bucaro (vas fictile odoriferum). People are fond of drinking out of these vessels on account of the smell of the clay. The women of the province of Alentejo acquire a habit of masticating the bucaro earth; and feel a great privation when they cannot indulge this vitiated taste.) Brown relates in his History of Jamaica that the crocodiles of South America swallow small stones and pieces of very hard wood, when the lakes which they inhabit are dry, or when they are in want of food. M. Bonpland and I observed in a crocodile, eleven feet long, which we dissected at Batallez, on the banks of the Rio Magdalena, that the stomach of this reptile contained half-digested fish, and rounded fragments of granite three or four inches in diameter. It is difficult to admit that the crocodiles swallow these stony masses accidentally, for they do not catch fish with their lower jaw resting on the ground at the bottom of the river. The Indians have framed the absurd hypothesis that these indolent animals like to augment their weight, that they may have less trouble in diving. I rather think that they load their stomach with large pebbles to excite an abundant secretion of the gastric juice. The experiments of Majendie render this explanation extremely probable. With respect to the habit of the granivorous birds, particularly the gallinaceae and ostriches, of swallowing sand and small pebbles, it has been hitherto attributed to an instinctive desire of accelerating the trituration of the aliments in a muscular and thick stomach.

We have mentioned that tribes of Negroes on the Gambia mingle clay with their rice. Some families of Ottomacs were perhaps formerly accustomed to cause the maize and other farinaceous seeds to rot in their poya, in order to eat earth and amylaceous matter together: possibly it was a preparation of this kind, that Father Gumilla described indistinctly in the first volume of his work when he affirms that the Guamos and the Ottomacs feed upon earth only because it is impregnated with the sustancia del maiz (substance of maize) and the fat of the cayman. I have already observed that neither the present missionary of Uruana, nor Fray Juan Gonzales, who lived long in those countries, knew anything of this mixture of animal and vegetable substances with the poya. Perhaps Father Gumilla has confounded the preparation of the earth which the natives swallow with the custom they still retain (of which M. Bonpland acquired the certainty on the spot) of burying in the ground the beans of a species of mimosacea,* (* Of the genus Inga.) to cause them to enter into decomposition so as to reduce them into a white bread, savoury, but difficult of digestion. I repeat that the balls of poya, which we took from the winter stores of the Indians, contained no trace of animal fat, or of amylaceous matter. Gumilla being one of the most credulous travellers we know, it almost perplexes us to credit facts which even he has thought fit to reject. In the second volume of his work he however gainsays a great part of what he advanced in the first; he no longer doubts that half at least (a lo menos) of the bread of the Ottomacs and the Guamos is clay. He asserts, that children and full grown persons not only eat this bread without suffering in their health, but also great pieces of pure clay (muchos terrones de pura greda.) He adds that those who feel a weight on the stomach physic themselves with the fat of the crocodile which restores their appetite and enables them to continue to eat pure earth.* (* Gumilla volume 2 page 260.) It is certain that the Guamos are very fond, if not of the fat, at least of the flesh of the crocodile, which appeared to us white, and without any smell of musk. In Sennaar, according to Burckhardt, it is equally esteemed, and sold in the markets.
