Chapter 2: 24 (4)

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.

The little village of Uruana is more difficult to govern than most of the other missions. The Ottomacs are a restless, turbulent people, with unbridled passions. They are not only fond to excess of the fermented liquors prepared from cassava and maize, and of palm-wine, but they throw themselves into a peculiar state of intoxication, we might say of madness, by the use of the powder of niopo. They gather the long pods of a mimosacea which we have made known by the name of Acacia niopo,* cut them into pieces, moisten them, and cause them to ferment. (* It is an acacia with very delicate leaves, and not an Inga. We brought home another species of mimosacea (the chiga of the Ottomacs and the sepa of the Maypures) that yields seeds, the flour of which is eaten at Uruana like cassava. From this flour the chiga bread is prepared, which is so common at Cunariche, and on the banks of the Lower Orinoco. The chiga is a species of Inga, and I know of no other mimosacea that can supply the place of the cerealia.) When the softened seeds begin to grow black, they are kneaded like a paste; mixed with some flour of cassava and lime procured from the shell of a helix, and the whole mass is exposed to a very brisk fire, on a gridiron made of hard wood. The hardened paste takes the form of small cakes. When it is to be used, it is reduced to a fine powder, and placed on a dish five or six inches wide. The Ottomac holds this dish, which has a handle, in his right hand, while he inhales the niopo by the nose, through the forked bone of a bird, the two extremities of which are applied to the nostrils. This bone, without which the Ottomac believes that he could not take this kind of snuff, is seven inches long: it appeared to me to be the leg-bone of a large sort of plover. The niopo is so stimulating that the smallest portions of it produce violent sneezing in those who are not accustomed to its use. Father Gumilla says this diabolical powder of the Ottomacs, furnished by an arborescent tobacco-plant, intoxicates them through the nostrils (emboracha por las narices), deprives them of reason for some hours, and renders them furious in battle. However varied may be the family of the leguminous plants in the chemical and medical properties of their seeds, juices, and roots, we cannot believe, from what we know hitherto of the group of mimosaceae, that it is principally the pod of the Acacia niopo which imparts the stimulant power to the snuff of the Ottomacs. This power is owing, no doubt, to the freshly calcined lime. We have shown above that the mountaineers of the Andes of Popayan, and the Guajiros, who wander between the lake of Maracaybo and the Rio la Hacha, are also fond of swallowing lime as a stimulant, to augment the secretion of the saliva and the gastric juice.

A custom analogous to the use of the niopo just described was observed by La Condamine among the natives of the Upper Maranon. The Omaguas, whose name is rendered celebrated by the expeditions attempted in search of El Dorado, have like the Ottomacs a dish, and the hollow bone of a bird, by which they convey to their nostrils their powder of curupa. The seed that yields this powder is no doubt also a mimosacea; for the Ottomacs, according to Father Gili, designate even now, at the distance of one hundred and sixty leagues from the Amazon, the Acacia niopo by the name of curupa. Since the geographical researches which I have recently made on the scene of the exploits of Philip von Huten, and the real situation of the province of Papamene, or of the Omaguas, the probability of an ancient communication between the Ottomacs of the Orinoco and the Omaguas of the Maranon has become more interesting and more probable. The former came from the Meta, perhaps from the country between the Meta and the Guaviare; the latter assert that they descended in great numbers to the Maranon by the Rio Jupura, coming from the eastern declivity of the Andes of New Grenada. Now, it is precisely between the Guayavero (which joins the Guaviare) and the Caqueta (which takes lower down the name of Japura) that the country of the Omagua appears to be situate, of which the adventurers of Coro and Tocuyo in vain attempted the conquest. There is no doubt a striking contrast between the present barbarism of the Ottomacs and the ancient civilization of the Omaguas; but all parts of the latter nation were not perhaps alike advanced in civilization, and the example of tribes fallen into complete barbarism are unhappily but too common in the history of our species. Another point of resemblance may be remarked between the Ottomacs and the Omaguas. Both of these nations are celebrated among all the tribes of the Orinoco and the Amazon for their employment of caoutchouc in the manufacture of various articles of utility.

The real herbaceous tobacco* (for the missionaries have the habit of calling the niopo or curupa tree-tobacco) has been cultivated from time immemorial by all the native people of the Orinoco; and at the period of the conquest the habit of smoking was found to be alike spread over both North and South America.

(* The word tobacco (tabacco), like the words savannah, maize, cacique, maguey (agave), and manati, belongs to the ancient language of Haiti, or St. Domingo. It did not properly denote the herb but the tube through which the smoke was inhaled. It seems surprising that a vegetable production so universally spread should have different names among neighbouring people. The pete-ma of the Omaguas is, no doubt, the pety of the Guaranos; but the analogy between the Cabre and Algonkin (or Lenni-Lenape) words which denote tobacco may be merely accidental. The following are the synonyms in thirteen languages.

North America. Aztec or Mexican; yetl: Algonkin; sema: Huron; oyngoua.

South America. Peruvian or Quichua; sayri: Chiquito; pais. Guarany; pety: Vilela; tusup: Mbaja (west of the Paraguay), nalodagadi: Moxo (between the Rio Ucayale and the Rio Madeira); sabare. Omagua; petema. Tamanac; cavas. Maypure; jema. Cabre; scema.)

The Tamanacs and the Maypures of Guiana wrap maize-leaves round their cigars, as the Mexicans did at the time of the arrival of Cortes. The Spaniards have substituted paper for the leaves of maize in imitation of them. The poor Indians of the forests of the Orinoco know as well as did the great nobles at the court of Montezuma that the smoke of tobacco is an excellent narcotic; and they use it not only to procure their afternoon nap, but also to put themselves into that state of quiescence, which they call dreaming with the eyes open, or day-dreaming. The use of tobacco appears to me to be now very rare in the missions; and in New Spain, to the great regret of the revenue-officers, the natives, who are almost all descended from the lowest class of the Aztec people, do not smoke at all. Father Gili affirms that the practice of chewing tobacco is unknown to the Indians of the Lower Orinoco. I rather doubt the truth of this assertion, having been told that the Sercucumas of the Erevato and the Caura, neighbours of the whitish Taparitos, swallow tobacco chopped small, and impregnated with some other very stimulant juices, to prepare themselves for battle. Of the four species of nicotiana cultivated in Europe* (* Nicotiana tabacum, N. rustica, N. paniculata, and N. glutinosa.) we found only two growing wild; but the Nicotiana loxensis, and the Nicotiana andicola, which I found on the back of the Andes, at the height of eighteen hundred and fifty toises (almost the height of the Peak of Teneriffe), are very similar to the N. tabacum and N. rustica. The whole genus, however, is almost exclusively American, and the greater number of the species appeared to me to belong to the mountainous and temperate region of the tropics.

It was neither from Virginia, nor from South America, but from the Mexican province of Yucatan, that Europe received the first tobacco seeds, about the year 1559.* (* The Spaniards became acquainted with tobacco in the West India Islands at the end of the 15th century. I have already mentioned that the cultivation of this narcotic plant preceded the cultivation of the potato in Europe more than 120 or 140 years. When Raleigh brought tobacco from Virginia to England in 1586, whole fields of it were already cultivated in Portugal. It was also previously known in France, where it was brought into fashion by Catherine de Medicis, from whom it received the name of herbe a la reine, the queen's herb.) The celebrated Raleigh contributed most to introduce the custom of smoking among the nations of the north. As early as the end of the sixteenth century bitter complaints were made in England of this imitation of the manners of a savage people. It was feared that, by the practice of smoking tobacco, Englishmen would degenerate into a barbarous state.* (* This remarkable passage of Camden is as follows, Annal. Elizabet. page 143 1585; "ex illo sane tempore [tabacum] usu cepit esse creberrimo in Anglia et magno pretio dum quamplurimi graveolentem illius fumum per tubulum testaceum hauriunt et mox e naribus efflant; adeo ut Auglornm corporum in barbarorum naturam degenerasse videantur, quum iidem ac barbari delectentur." We may see from this passage that they emitted the smoke through the nose; but at the court of Montezuma the pipe was held in one hand, while the nostrils were stopped with the other, in order that the smoke might be more easily swallowed. Life of Raleigh volume 1 page 82.)

When the Ottomacs of Uruana, by the use of niopo (their arborescent tobacco), and of fermented liquors, have thrown themselves into a state of intoxication, which lasts several days, they kill one another without ostensibly fighting. The most vindictive among them poison the nail of their thumb with curare; and, according to the testimony of the missionary, the mere impression of this poisoned nail may become a mortal wound if the curare be very active and immediately mingle with the mass of the blood. When the Indians, after a quarrel at night, commit a murder, they throw the dead body into the river, fearing that some indications of the violence committed on the deceased may be observed. "Every time," said Father Bueno, "that I see the women fetch water from a part of the shore to which they are not accustomed to go, I suspect that a murder has been committed in my mission."

We found in the Indian huts at Uruana the vegetable substance called touchwood of ants,* (* Yesca de hormigas.) with which we had become acquainted at the Great Cataracts, and which is employed to stop bleeding. This substance, which might less improperly be called ants' nests, is in much request in a region whose inhabitants are of so turbulent a character. A new species of ant, of a fine emerald-green (Formica spinicollis), collects for its habitation a cotton-down, of a yellowish-brown colour, and very soft to the touch, from the leaves of a melastomacea. I have no doubt that the yesca or touchwood of ants of the Upper Orinoco (the animal is found, we were assured, only south of Atures) will one day become an article of trade. This substance is very superior to the ants' nests of Cayenne, which are employed in the hospitals of Europe, but can rarely be procured.

On the 7th of June we took leave with regret of Father Ramon Bueno. Of the ten missionaries whom we had found in different parts of the vast extent of Guiana, he alone appeared to me to be earnestly attentive to all that regarded the natives. He hoped to return in a short time to Madrid, where he intended to publish the result of his researches on the figures and characters that cover the rocks of Uruana.

In the countries we had just passed through, between the Meta, the Arauca, and the Apure, there were found, at the time of the first expeditions to the Orinoco, in 1535, those mute dogs, called by the natives maios, and auries. This fact is curious in many points of view. We cannot doubt that the dog, whatever Father Gili may assert, is indigenous in South America. The different Indian languages furnish words to designate this animal, which are scarcely derived from any European tongue. To this day the word auri, mentioned three hundred years ago by Alonzo de Herrera, is found in the Maypure. The dogs we saw at the Orinoco may perhaps have descended from those that the Spaniards carried to the coast of Caracas; but it is not less certain that there existed a race of dogs before the conquest, in Peru, in New Granada, and in Guiana, resembling our shepherds' dogs. The allco of the natives of Peru, and in general all the dogs that we found in the wildest countries of South America, bark frequently. The first historians, however, all speak of mute dogs (perros mudos). They still exist in Canada; and, what appears to me worthy of attention, it was this dumb variety that was eaten in preference in Mexico,* and at the Orinoco. (* See on the Mexican techichi and on the numerous difficulties that occur in the history of mute dogs and dogs destitute of hair the Views of Nature Bohn's edition page 85.) A very well informed traveller, M. Giesecke, who resided six years in Greenland, assured me that the dogs of the Esquimaux, which pass their lives in the open air and bury themselves in winter beneath the snow, do not bark, but howl like wolves.* (* They sit down in a circle, one of them begins to howl alone and the others follow in the same tone. The groups of alouate monkeys howl in the same manner, and among them the Indians distinguish the leader of the band. It was the practice at Mexico to castrate the mute dogs in order to fatten them. This operation must have contributed to alter the organ of the voice.)

The practice of eating the flesh of dogs is now entirely unknown on the banks of the Orinoco; but as it is a Tartar custom spread through all the eastern part of Asia, it appears to me highly interesting for the history of nations to have ascertained that it existed heretofore in the hot regions of Guiana and on the table-lands of Mexico. I must observe, also, that on the confines of the province of Durango, at the northern extremity of New Spain, the Comanches have preserved the habit of loading the backs of the great dogs that accompany them in their migrations with their tents of buffalo-leather. It is well known that employing dogs as beasts of burthen and of draught is equally common near the Slave Lake and in Siberia. I dwell on these features of conformity in the manners of nations, which become of some weight when they are not solitary, and are connected with the analogies furnished by the structure of languages, the division of time, and religious creeds and institutions.

We passed the night at the island of Cucuruparu, called also Playa de la Tortuga, because the Indians of Uruana go thither to collect the turtles' eggs. It is one of the best determined points of latitude along the banks of the Orinoco. I was there fortunate enough to observe the passage of three stars over the meridian. To the east of the island is the mouth of the Cano de la Tortuga, which descends from the mountains of Cerbatana, continually wrapped in electric clouds. On the southern bank of the Cano, between the tributary streams Parapara and Oche, lies the almost ruined mission of San Miguel de la Tortuga. The Indians assured us that the environs of this little mission abound in otters with a very fine fur, called by the Portuguese water-dogs (perritos de agua); and what is still more remarkable, in lizards (lagartos) with only two feet. The whole of this country, which is very accessible between the Rio Cuchivero and the strait of Baraguan, is worthy of being visited by a well-informed zoologist. The lagarto destitute of hinder extremities is perhaps a species of Siren, different from the Siren lacertina of Carolina. If it were a saurian, a real Bimanis (Chirotes, Cuvier), the natives would not have compared it to a lizard. Besides the arrau turtles, of which I have in a former place given a detailed account, an innumerable quantity of land tortoises also, called morocoi, are found on the banks of the Orinoco, between Uruana and Encaramada. During the great heats of summer, in the time of drought, these animals remain without taking food, hidden beneath stones, or in the holes they have dug. They issue from their shelter and begin to eat, only when the humidity of the first rains penetrates into the earth. The terekay, or tajelu turtle which lives in fresh water, has the same habits. I have already spoken of the summer-sleep of some animals of the tropics. As the natives know the holes in which the tortoises sleep amidst the dried lands, they get out a great number at once, by digging fifteen or eighteen inches deep. Father Gili says that this operation, which he had seen, is not without danger, because serpents often bury themselves in summer with the terekays.

From the island of Cucuruparu, to the capital of Guiana, commonly called Angostura, we were but nine days on the water. The distance is somewhat less than ninety-five leagues. We seldom slept on shore but the torment of the mosquitos diminished in proportion as we advanced. We landed on the 8th of June at a farm (Hato de San Rafael del Capuchino) opposite the mouth of the Rio Apure. I obtained some good observations of latitude and longitude.* (* I had found, on the 4th of April, for the Boca del Rio Apure (on the western bank of the Orinoco), the latitude 7 degrees 36 minutes 30 seconds, the longitude 59 degrees 7 minutes 30 seconds; on the 8th of June I found, for the Hato del Capuchino (on the eastern bank of the Orinoco), the latitude 7 degrees 37 minutes 45 seconds, the longitude 69 degrees 5 minutes 30 seconds.) Having two months before taken horary angles on the bank opposite Capuchino, these observations were important for determining the rate of my chronometer, and connecting the situations on the Orinoco with those on the shore of Venezuela. The situation of this farm, being at the point where the Orinoco changes its course (which had previously been from south to north), and runs from west to east, is extremely picturesque. Granite rocks rise like islets amidst vast meadows. From their tops we discerned towards the north the Llanos of Calabozo bounding the horizon. We had been so long accustomed to the aspect of forests, that this view made a powerful impression on us. The steppes after sunset assume a tint of greenish gray. The visual ray being intercepted only by the rotundity of the earth, the stars seemed to rise as from the bosom of the ocean, and the most experienced mariner would have fancied himself placed on a projecting cape of a rocky coast. Our host was a Frenchman who lived amidst his numerous herds. Though he had forgotten his native language, he seemed pleased to learn that we came from his country, which he had left forty years before; and he wished to retain us for some days at his farm. The small towns of Caycara and Cabruta were only a few miles distant from the farm; but during part of the year our host was in complete solitude. The Capuchino becomes an island by the inundations of the Apure and the Orinoco, and the communication with the neighbouring farms can be kept up only by means of a boat. The horned cattle then seek the higher grounds which extend on the south toward the chain of the mountains of Encaramada. This granitic chain is intersected by valleys which contain magnetic sands (granulary oxidulated iron), owing no doubt to the decomposition of some amphibolic or chloritic strata.

On the morning of the 9th of June we met a great number of boats laden with merchandize sailing up the Orinoco, in order to enter the Apure. This is a commercial road much frequented between Angostura and the port of Torunos in the province of Varinas. Our fellow-traveller, Don Nicolas Soto, brother-in-law of the governor of Varinas, took the same course to return to his family. At the period of the high waters, several months are lost in contending with the currents of the Orinoco, the Apure, and the Rio de Santo Domingo. The boatmen are forced to carry out ropes to the trunks of trees and thus warp their canoes up. In the great sinuosities of the river whole days are sometimes passed without advancing more than two or three hundred toises. Since my return to Europe the communications between the mouth of the Orinoco and the provinces situated on the eastern slope of the mountains of Merida, Pamplona, and Santa Fe de Bogota, have become more active; and it may be hoped that steamboats will facilitate these long voyages on the Lower Orinoco, the Portuguesa, the Rio Santo Domingo, the Orivante, the Meta, and the Guaviare. Magazines of cleft wood might be formed, as on the banks of the great rivers of the United States, sheltering them under sheds. This precaution would be indispensable, as, in the country through which we passed, it is not easy to procure dry fuel fit to keep up a fire beneath the boiler of a steam-engine.

We disembarked below San Rafael del Capuchino, on the right, at the Villa de Caycara, near a cove called Puerto Sedeno. The Villa is merely a few houses grouped together. Alta Gracia, la Ciudad de la Piedra, Real Corona, Borbon, in short all the towns or villas lying between the mouth of the Apure and Angostura, are equally miserable. The presidents of the missions, and the governors of the provinces, were formerly accustomed to demand the privileges of villas and ciudades at Madrid, the moment the first foundations of a church were laid. This was a means of persuading the ministry that the colonies were augmenting rapidly in population and prosperity. Sculptured figures of the sun and moon, such as I have already mentioned, are found near Caycara, at the Cerro del Tirano.* (* The tyrant after whom these mountains are named is not Lope de Aguirre, but probably, as the name of the neighbouring cove seems to prove, the celebrated conquistador Antonio Sedeno, who, after the expedition of Herrera, sought to penetrate by the Orinoco to the Rio Meta. He was in a state of rebellion against the audiencia of Santo Domingo. I know not how Sedeno came to Caycara; for historians relate that he was poisoned on the banks of the Rio Tisnado, one of the tributary streams of the Portuguesa.) It is the work of the old people (that is of our fathers), say the natives. On a rock more distant from the shore, and called Tecoma, the symbolic figures are found, it is said, at the height of a hundred feet. The Indians knew heretofore a road, that led by land from Caycara to Demerara and Essequibo.

On the northern bank of the Orinoco, opposite Caycara, is the mission of Cabruta, founded by the Jesuit Rotella, in 1740, as an advanced post against the Caribs. An Indian village, known by the name of Cabritu,* had existed on the same spot for several ages. (* A cacique of Cabritu received Alonzo de Herrera at his dwelling, on the expedition undertaken by Herrera for ascending the Orinoco in 1535.) At the time when this little place became a Christian settlement, it was believed to be situate in 5 degrees latitude, or two degrees forty minutes more to the south than I found it by direct observations made at San Rafael, and at La Boca del Rio Apure. No idea was then conceived of the direction of a road that could lead by land to Nueva Valencia and Caracas, which were supposed to be at an immense distance. The merit of having first crossed the Llanos to go to Cabruta from the Villa de San Juan Baptista del Pao belongs to a woman. Father Gili relates that Dona Maria Bargas was so devoted to the Jesuits that she attempted herself to discover the way to the missions. She was seen with astonishment to arrive at Cabruta from the north. She took up her abode near the fathers of St. Ignatius, and died in their settlements on the banks of the Orinoco. Since that period the northern part of the Llanos has been considerably peopled; and the road leading from the valleys of Aragua by Calabozo to San Fernando de Apure and Cabruta is much frequented. The chief of the famous expedition of the boundaries made choice of the latter place in 1754 to establish dock-yards for building the vessels necessary for conveying his troops intended for the Upper Orinoco. The little mountain that rises northeast of Cabruta can be discerned from afar in the steppes and serves as a landmark for travellers.

We embarked in the morning at Caycara; and driving with the current of the Orinoco, we soon passed the mouth of the Rio Cuchivero, which according to ancient tradition is the country of the Aikeambenanos, or women without husbands; and we there reached the paltry village of Alta Gracia, which is called a Spanish town. It was near this place that Jose de Iturriaga founded the Pueblo de Ciudad Real, which still figures on the most modern maps, though it has not existed for fifty years past, on account of the insalubrity of its situation. Beyond the point where the Orinoco turns to the east, forests are constantly seen on the right bank, and the llanos or steppes of Venezuela on the left. The forests which border the river are not however so thick as those of the Upper Orinoco. The population, which augments perceptibly as you advance toward the capital, comprises but few Indians, and is composed chiefly of whites, negroes, and men of mixed descent. The number of the negroes is not great; but here, as everywhere else, the poverty of their masters does not tend to procure for them more humane treatment. An inhabitant of Caycara had just been condemned to four years' imprisonment, and a fine of one hundred piastres for having, in a paroxysm of rage, tied a negress by the legs to the tail of his horse, and dragged her at full gallop through the savannah till she expired. It is gratifying to record that the Audiencia was generally blamed in the country for not having punished more severely so atrocious an action. Yet some few persons, who pretended to be the most enlightened and most sagacious of the community, deemed the punishment of a white contrary to sound policy, at the moment when the blacks of St. Domingo were in complete insurrection. Since I left those countries, civil dissensions have put arms into the hands of the slaves; and fatal experience has led the inhabitants of Venezuela to regret that they refused to listen to Don Domingo Tovar, and other right-thinking men, who, as early as the year 1795, lifted up their voices in the cabildo of Caracas, to prevent the introduction of blacks, and to propose means that might ameliorate their condition.

After having slept on the 10th of June in an island in the middle of the river (I believe that called Acaru by Father Caulin), we passed the mouth of the Rio Caura. This, the Aruy and the Carony, are the largest tributary streams which the Orinoco receives on its right bank. All the Christian settlements are near the mouth of the river; and the villages of San Pedro, Aripao, Urbani, and Guaraguaraico, succeed each other at the distance of a few leagues. The first and the most populous contains only about two hundred and fifty souls. San Luis de Guaraguaraico is a colony of negroes, some freed and others fugitives from Essequibo. This colony merits the particular attention of the Spanish Government, for it can never be sufficiently recommended to endeavour to attach the slaves to the soil, and suffer them to enjoy as farmers the fruits of their agricultural labours. The land on the Caura, for the most part a virgin soil, is extremely fertile. There are pasturages for more than 15,000 beasts; but the poor inhabitants have neither horses nor horned cattle. More than five-sixths of the banks of the Caura are either desert, or occupied by independent and savage tribes. The bed of the river is twice choked up by rocks: these obstructions occasion the famous Raudales of Mura and of Para or Paru, the latter of which has a portage, because it cannot be passed by canoes. At the time of the expedition of the boundaries, a small fort was erected on the northern cataract, that of Mura; and the governor, Don Manuel Centurion, gave the name of Ciudad de San Carlos to a few houses which some families, consisting of whites and mulattos, had constructed near the fort. South of the cataract of Para, at the confluence of the Caura and the Erevato, the mission of San Luis was then situated; and a road by land led thence to Angostura, the capital of the province. All these attempts at civilization have been fruitless. No village now exists above the Raudal of Mura; and here, as in many other parts of the colonies, the natives may be said to have reconquered the country from the Spaniards. The valley of Caura may become one day or other highly interesting from the value of its productions, and the communications which it affords with the Rio Ventuari, the Carony, and the Cuyuni. I have shown above the importance of the four tributary streams which the Orinoco receives from the mountains of Parima. Near the mouth of the Caura, between the villages of San Pedro de Alcantara and San Francisco de Aripao, a small lake of four hundred toises in diameter was formed in 1790, by the sinking of the ground, consequent on an earthquake. It was a portion of the forest of Aripao, which sunk to the depth of eighty or a hundred feet below the level of the neighbouring land. The trees remained green for several months; and some of them, it was believed, continued to push forth leaves beneath the water. This phenomenon is the more worthy of attention as the soil of these countries is probably granitic. I doubt the secondary formations of the Llanos being continued southward as far as the valley of Caura.

On the 11th of June we landed on the right bank of the Orinoco at Puerto de los Frailes, at the distance of three leagues above the Ciudad de la Piedra, to take altitudes of the sun. The longitude of this point is 67 degrees 26 minutes 20 seconds, or 1 degree 41 minutes east of the mouth of the Apure. Farther on, between the towns of La Piedra and Muitaco, or Real Corona, are the Torno and Boca del Infierno, two points formerly dreaded by travellers. The Orinoco suddenly changes its direction; it flows first east, then north-north-west, and then again east. A little above the Cano Marapiche, which opens on the northern bank, a very long island divides the river into two branches. We passed on the south of this island without difficulty; northward, a chain of small rocks, half covered at high water, forms whirlpools and rapids. This is La Boca del Infierno, and the Raudal de Camiseta. The first expeditions of Diego Ordaz (1531) and Alonzo de Herrera (1535) have given celebrity to this bar. The Great Cataracts of the Atures and Maypures were then unknown; and the clumsy vessels (vergantines), in which travellers persisted in going up the river, rendered the passage through the rapids extremely difficult. At present no apprehension is felt in ascending or descending the Orinoco, at any season, from its mouth as far as the confluence of the Apure and the Meta. The only falls of water in this space are those of Torno or Camiseta, Marimara, and Cariven or Carichana Vieja. Neither of these three obstacles is to be feared with experienced Indian pilots. I dwell on these hydrographic details because a great political and commercial interest is now connected with the communications between Angostura and the banks of the Meta and the Apure, two rivers that lead to the eastern side of the Cordilleras of New Grenada. The navigation from the mouth of the Lower Orinoco to the province of Varinas is difficult only on account of the current. The bed of the river nowhere presents obstacles more difficult to be surmounted than those of the Danube between Vienna and Linz. We meet with no great bars, no real cataracts, until we get above the Meta. The Upper Orinoco, therefore, with the Cassiquiare and the Rio Negro, forms a particular system of rivers, where the active industry of Angostura and the shore of Caracas will remain long unknown.

I obtained horary angles of the sun in an island in the midst of the Boca del Infierno, where we had set up our instruments. The longitude of this point according to the chronometer is 67 degrees 10 minutes 31 seconds. I attempted to determine the magnetic dip and intensity, but was prevented by a heavy storm of rain. As the sky again became serene in the afternoon, we lay down to rest that night on a vast beach, on the southern bank of the Orinoco, nearly in the meridian of the little town of Muitaco, or Real Corona. I found the latitude by three stars to be 8 degrees 0 minutes 26 seconds, and the longitude 67 degrees 5 minutes 19 seconds. When the Observantin monks in 1752 made their first entradas on the territory of the Caribs, they constructed on this spot a small fort. The proximity of the lofty mountains of Araguacais renders Muitaco one of the most healthy places on the Lower Orinoco. There Iturriaga took up his abode in 1756, to repose after the fatigues of the expedition of the boundaries; and as he attributed his recovery to this hot rather than humid climate, the town, or more properly the village, of Real Corona took the name of Pueblo del Puerto sano. Going down the Orinoco more to the east, we left the mouth of the Rio Pao on the north, and that of the Arui on the south. The latter river, which is somewhat considerable, is often mentioned by Raleigh. The current of the Orinoco diminished in velocity as we advanced. I measured several times a base along the beach, to ascertain the time taken by floating bodies in traversing a known distance. Above Alta Gracia, near the mouth of the Rio Ujape, I had found the velocity of the Orinoco 2.3 feet in a second; between Muitaco and Borbon it was only 1.7 foot. The barometric observations made in the neighbouring steppes prove the small slope of the ground from the longitude of 69 degrees to the eastern coast of Guiana. We found in this country, on the right bank of the Orinoco, small formations of primitive grunstein, superimposed on granite (perhaps even embedded in the rock). We saw between Muitaco and the island of Ceiba a hill entirely composed of balls with concentric layers, in which we perceived a close mixture of hornblende and feldspar, with some traces of pyrites. The grunstein resembles that in the vicinity of Caracas; but it was impossible to ascertain the position of a formation which appeared to me to be of the same age as the granite of Parima. Muitaco was the last spot where we slept in the open air on the shore of the Orinoco: we proceeded along the river two nights more before we reached Angostura, which terminated our voyage.
