CHAPTER XVI. Lake of Tacarigua. — Hot Springs of Mariara. — Town of Nueva Valencia del Key. — Descent towards the Coasts of Porto Cabello. THE valleys of Aragua form a narrow basin between gra- nitic and calcareous mountains of unequal height. On the north, they are separated by the Sierra Mariara from the sea-coast ; and towards the south, the chain of Guacimo and Tusma serves them as a rampart against the heated air of the steppes. Groups of hills, high enough to deter- mine the course ol the waters, close this basin on the east and west like transverse dykes. We find these hUs between the Tuy and La Victoria, as well as on the road from Valencia to Nirgua, and at the mountains of Torito.* From * The lofty mountains of Los Teques, where the Tuy takes its source, may be looked upon as the eastern boundary of the valleys of Aragua. The level of the ground continues, in fact, to rise from La Victoria to the Hacienda de Tuy ; but the river Tuy, turning southward in the direction of the sierras of Guniraima and Tiara has found an issue on the east «, VOL. II. B LAKE OF VALENCIA. • this extraordinary configuration of the land, the little ri of the valleys of Aragua form a peculiar system, and direct their course towards a basin closed on all sides. These rivers do not bear their waters to the ocean ; they are collected in a lake ; and subject to the peculiar influence of evaporation, they lose themselves, if we may use the expression, in the atmosphere. On the existence of rivers and lakes, the fertility of the soil and the produce of culti- vation in these valleys depend. The aspect of the spot, and the experience of half a century, have proved that the level of the waters is not invariable ; the waste by evapora- tion, and the increase from the waters running into the lake, do not uninterruptedly balance each other. The labe being elevated one thousand feet above the neighbouring steppes of Calabozo, and one thousand three hundred and thirty-two feet above the level of the ocean, it has been suspected that there are subterranean communications and nitrations. The appearance of new islands, and the gradual retreat of the waters, have led to the belief that the lake may perhaps, in time, become entirely dry. An assemblage of physical circumstances so remarkable was well fitted to fix my attention on those valleys where the wild beauty of nature is embellished by agricultural industry, and the arts of rising civilization. The lake of Valencia, called Tacarigua by the Indians, exceeds in magnitude the lake of Neufchatel in Switzerland ; but its general form has more resemblance to the lake of Geneva, which is nearly at the same height above the level of the sea. As the slope of the ground in the- valleys of Aragua tends towards the south and the west, that* part of the basin still covered with water is the nearest to the southern chain of the mountains of Guigue, of Yusma, and of Guacimo, which stretch towards the high savannahs of Ocurnare. The opposite banks of the lake of Valencia display a singular contrast ; those on the south are desert, and almost uninhabited, and a screen of high momitains and it is more natural to consider as the limits of the basin of Aragua a line drawn through the sources of the streams flowing into the lake of Valencia. The charts and sections I have traced of the road from Cara- cas to Nueva Valencia, and from Porto Cabello to Villa de Cura. exhibit the whole of these geological relations. SCENERY OF THE LAKE. givea th< m a gloomy and monotonous aspect. The northern shore on the contrary, is cheerful, pastoral, and decked with the rich cultivation of the sugar-cane, coffee-tree, and cotton. Paths bordered with cestrums, azedaracs, and other shrubs always in flower, cross the plain, and join the scat- tered farms. Every house is surrounded by clumps of trees. The ceiba with its large yellow flowers* gives a peculiar character to the landscape, mingling its branches with those of the purple erythrina. This mixture of vind vegetable colours contrasts finely with the uniform tint of an un- clouded sky. In the season of drought, where the burning soil is covered with an undulating vapour, artificial irriga- tions preserve verdure and promote fertility. Here and there the granite rock pierces through the cultivated ground. Enormous stony masses rise abruptly in the midst of the valley. Bare and forked, they nourish a few succulent plants, which prepare mould for future ages. Often on the summit of these lonely hills may be seen a fig-tree or a clusia with fleshy leaves, which has fixed its roots in the rock, and towers over the landscape. With their dead and withered branches, these trees look like signals erected on a steep cliff. The form of these mounts unfolds the secret of their ancient origin ; for when the whole of this valley was filled with water, and the waves beat at the foot of the peaks of Mariara (the Devil's Nook)f and the chain of the coast, these rocky hills were shoals or islets. These features of a rich landscape, these contrasts be- tween the two banks of the lake of Valencia, often reminded me of the Pays de Vaud, where the soil, everywhere cul- tivated, and everywhere fertile, offers the husbandman, the shepherd, and the vine-dresser, the secure fruit of their labours, while, on the opposite side, Chablais presents only a mountainous and hall-desert country. In these distant climes surrounded by exotic productions, I lored to recall to mind the enchanting descriptions with which the aspect of the Leman lake and the rocks of La Meillerie inspired a great writer. Now, while in the centre of civilized Europe, I endeavour in my turn to paint the scenes of the New World, I do not imagine I present the reader with clearer * Camet tollendas (Bombax hibiscifolius). t £1 Rincon del Diablo. B 2 4 i A.FCIETTT EXTENT. images, or more precise ideas, by comparing our landscapes with those of the equinoctial regions. It cannot be too often repeated that nature, in every zone, whether wild or cultivated, smiling or majestic, lias an individual cha- racter. The impressions which she excites are infinitely varied, like the emotions produced by works of genius, according to the age in which they were conceived, and the diversity of language from which they in part derive their charm. We must limit our comparisons merely to dimen- sions and external form. We may institute a parallel between the colossal summit of Mont Blanc and the Himalaya Mountains; the cascades of the Pyrenees and those of the Cordilleras : but these comparisons, useful with respect to science, fail to convey an idea of the character- istics of nature in the temperate and torrid zones. On the banks of a lake, in a vast forest, at the foot of summits covered with eternal snow, it is not the mere magnitude of the objects which excites our admiration. That which speaks to the wul, which causes such profound and varied emotions, escapes our measurements as it does the forms of language. Those who feel powerfully the charms of nature cannot venture on comparing one with another, scenes totally different in character. But it is not alone the picturesque beauties of the lake of Valencia that have given celebrity to its banks. This basin presents several other phenomena, and suggests ques- tions, the solution of which is interesting alike to physical science and to the well-being of the inhabitants. "What are the causes of the diminution of the waters of the lake ? Is this diminution more rapid now than in former ages ? Can we presume that an equilibrium between the waters flowing in and the waters lost will be shortly re-established, or may we apprehend that the lake will entirely disappear ? According to astronomical observations made at La Vic- toria, Hacienda de Cura, Nueva Valencia, and Gruigue, the length of the lake in its present state from Cagua to Gruayos, is ten leagues, or twenty-eight thousand eight hundred toises. Its breadth is very unequal. If we judge fr.om the latitudes of the mouth of the Rio Cura and the village of Gruigue, it nowhere surpasses 2*3 leagues, or six thousand five hundred toises ; most commonly it is but four DIMINUTION OF THE LAKE. & cr five miles. The dimensions, as deduced from my observa- tions are much less than those hitherto adopted by the natives. It might be thought that, to form a precise idea of the progressive diminution of the waters, it would be sufficient to compare the present dimensions of the lake with those attributed to it by ancient chroniclers; by Oviedo for instance, in his History of the Province of Vene- zuela, published about the year 1723. This writer in his emphatic style, assigns to "this inland sea, this monstruoso cuerpo de la lagunade Valencia"* fourteen leagues in length and six in breadth. He affirms that at a small distance from the shore the lead finds no bottom ; and that large floating islands cover the surface of the waters, which are constantly agitated by the winds. No importance can be attached to estimates which, without being founded on any measurement, are expressed in leagues (leguas) reckoned in the colonies at three thousand, five thousand, and six thou- sand six hundred and fifty varas.-\ Oviedo, who must so often have passed over the valleys of Aragua, asserts that the town of Nueva Valencia del Eey was built in 1555, at the distance of half a league from the lake ; and that the proportion between the length of the lake and its breadth, is as seven to three. At present, the town of Valencia is separated from the lake by level ground of more than two thousand seven hundred toises (which Oviedo would no doubt have estimated as a space of a league and a half) ; and the length of the basin of the lake is to its breadth as 10 to 2-3, or as 7 to 1/6. The appearance of the * " Enormous body of the lake of Valencia." f Seamen being the first, and for a long time the only, persons who introduced into the Spanish colonies any precise ideas on the astrono- mical position and distances of places, the legua nautica of 6650 varas, or of 2854 toises (20 in a degree), was originally used in Mexico and throughout South America ; but this legua nautica has been gradually reduced to one-half or one-third, on account of the slowness of tra- velling across steep mountains, or dry and burning plains. The common people measure only time directly ; and then, by arbitrary hypotheses, infer from the time the space of ground travelled over. In the course of my geographical researches, I have had frequent opportunities of exa- mining the real value of these leagues, by comparing the itinerary dis- tances between points lying under the same meridian with the difference of latitudes. 6 CHANGES OF LETEL. soil between Valencia and G-uigue, the little hills rising abruptly in the plain east of the Cano de Cambury, some of which (el Islote and la Isla de la Negra or Caratapona) have even preserved the name of islands, sufficiently prove that the waters have retired considerably since the time of Oviedo. "With respect to the change in the general form of the lake, it appears to me improbable that in the seven- teenth century its breadth was nearly the half of its length. The situation of the granite mountains of Mariara and of Guigue, the slope of the ground which rises more rapidly towards the north and south than towards the east and west, are alike repugnant to this supposition. In treating the long-discussed question of the diminution of the waters, I conceive we must distinguish between the different periods at which the sinking of their level has taken place. Wherever we examine the valleys of rivers, or the basins of lakes, we see the ancient shore at great dis- tances. No doubt seems now to be entertained, that our rivers and lakes have undergone immense diminutions ; but many geological facts remind us also, that these great changes in the distribution of the waters have preceded all historical times; and that for many thousand years most lakes have attained a permanent equilibrium between the produce of the water flowing in, and that of evaporation and nitration. "Whenever we find this equilibrium broken, it will be well rather to examine whether the rupture be not owing to causes merely local, and of very recent date, than to admit an uninterrupted diminution of the water. This reasoning is conformable to the more circumspect method of modern science. At a time when the physical history of the world, traced by the genius of some eloquent writers, borrowed all its charms from the fictions of imagi- nation, the phenomenon of which we are treating would have been adduced as a new proof of the contrast these writers sought to establish between the two continents. To demonstrate that America rose later than Asia and Europe from the bosom of the waters, the lake of Tacarigua would have been described as one of those interior basins which have not yet become dry by the effects of slow and gradual evaporation. I have no doubt that, in very remote times, the whole valley, from the foot of the mountains of RETREAT OF THTT WATEE. 7 Cocuyza to those of Torito and Nirgua, and from La Sierra de Mariara to the chain of Guigue, of Guacimo, and La Palma, was filled with water. Everywhere the form of the promontories, and their steep declivities, seem to indicate the shore of an alpine lake, similar to those of Stvria and Tyrol. The same little helicites, the same valvataB, which now live in the lake of Valencia, are found in layers of three or four feet thick as far inland as Turmero and La Concesion near La Victoria. These facts undoubtedly iirove a retreat of the waters ; but nothing indicates that this retreat has continued from a very remote period to our days. The valleys of Aragua are among the portions of Venezuela most anciently peopled; and yet there is no mention in Oviedo, or any other old chronicler, of a sensible diminution of the lake. Must we suppose, that this phenomenon escaped their observation, at a time when the Indians far exceeded the white population, and when the banks of the lake were *ess inhabited? Within half a century, and particularly within these thirty years, the natural desiccation of this great basin has excited general attention. We find vast tracts of land which were formerly inundated, now dry, and already cultivated with plantains, sugar-canes, or cotton. Wherever a hut is erected on the bank of the lake, we see the shore receding from year to year. We discover islands, which, in consequence of the retreat of the waters, are just beginning to be joined to the continent, as for instance the rocky island of Culebra, in the direction of Guigue ; other islands already form promontories, as the Morro, between Guigue and Nueva Valencia, and La Cabrera, south-east of Mariara ; others again are now rising in the islands them- selves like scattered hills. Among these last, so easily recognized at a distance, some are only a quarter of a mile, others a league from the present shore. I may cite as the most remarkable three granite islands, thirty or forty toises high, on the road from the Hacienda de Cura to Aguas Calientes; and at the western extremity of the lake, the Serrito de Don Pedro, Islote, and Caratapona. On visiting two islands* entirely surrounded by water, we found in the * Isla de Cura and Cabo Blanco. The promontory of Cabrera has been connected with the shore ever since the year 1750 or 1760 by a little f alley, which bears the name of PorUclmelo. 8 SUPPOSED OUTLET. midst of brushwood, on small flats (four, six, and even eighl toises height above the surface of the lake,) fine sand mixed with helicites, anciently deposited by the waters. In each of these islands may be perceived the most certain traces of the gradual sinking of the waters. But still farther (and this accident is regarded by the inhabitants as a marvellous phe- nomenon) in 1796 three new islands appeared to the east of the island Caiguira, in the same direction as the islands Burro, Otama, and Zorro, These new islands, called by the people Los nuevos Penones, or Los Aparecidos^ form a kind of banks with surfaces quite flat. They rose, in 1800, more than a foot above the mean level of the water. It has already been observed that the lake of Valencia,, like the lakes of the valley of Mexico, forms the centre of a little system of rivers, none of which have any com- munication with the ocean. These rivers, most of which deserve only the name of torrents, or brooks,f are twelve or fourteen in number. The inhabitants, little acquainted with the effects of evaporation, have long imagined that the lake has a subterranean outlet, by which a quantity of water runs out equal to that which flows in by the rivers. Some suppose tha^ this outlet communicates with grottos,, supposed to be at great depth; others believe that the water flows through an oblique channel into the basin of the ocean. These bold hypotheses on the communi- cation between two neighbouring basins have presented themselves in every zone to the imagination of the igno- rant, as well as to that of the learned; for the latter, without confessing it, sometimes repeat popular opinions in scientific language. "We hear of subterranean gulfs and outlets in the New World, as on the shores of the Caspian sea, though the lake of Tacarigua is two hundred and twenty-two toises higher, and the Caspian sea fifty-four toises lower, than the sea; and though it is well known, that fluids find the same level, when they communicate by a lateral channel. * Los Nuevos Penones (the New Rocks).

DIMINUTION or FOHESTS. The changes which the destruction of forests, the clearing of plains, and the cultivation of indigo, have produced within half a century in the quantity of water flowing in on the one hand, and on the other the evaporation of the soil, and the dryness of the atmosphere, present causes sufficiently powerful to explain the progressive diminution of the lake of Valencia. I cannot concur in the opinion of M. Depons * (who visited these countries since I was there) " that to set the mind at rest, and for the honour of science," a sub- terranean issue must be admitted. By felling the trees which cover the tops and the sides of mountains, men in every climate prepare at once two calamities for future gene- rations ; want of fuel and scarcity of water. Trees, by the nature of their perspiration, and the radiation from their leaves in a sky without clouds, surround themselves with an atmosphere constantly cold and misty. They affect the copiousness of springs, not, as was long believed, by a pecu- liar attraction for the vapours diffused through the air, but because, by sheltering the soil from the direct action of the sun, they diminish the evaporation of water produced by rain. When forests are destroyed, as they are everywhere in America by the European planters, with imprudent pre- cipitancy, the springs are entirely dried up, or become less abundant. The beds of the rivers, remaining dry during a part of the year, are converted into torrents whenever great rains fall on the heights. As the sward and moss disappear with the brushwood from the sides of the moun- tains, the waters falling in ram are no longer impeded in their course ; and instead of slowly augmenting the level of the rivers by progressive nitrations, they furrow, during heavy snowers, the sides of the hills, bearing down the loosened soil, and forming sudden and destructive inunda- tions. Hence it results, that the clearing of forests, the want of permanent springs, and the existence of torrents, are three phenomena closely connected together. Countries * In his 'Voyage & la Terre Ferme,' M. Depons says, "The small extent of the surface of the lake renders 'mpossible the supposition that evaporation alone, however considerable within the tropics, could remove M much water as the rivers furnish." In the sequel, the author himself seems to abandon what he terms " this occult case, the hypothesis of an aperture." > ttf 10 *ATE OF EVAPORATION. situated in opposite hemispheres, as, for example, Lombard/ bordered by the Alps, and Lower Peru inclosed between the Pacific and the Cordillera of the Andes, afford striking proofs of the justness of this assertion. Till the middle of the last century, the mountains round the valleys of Aragua were covered with forests. Great trees of the families of mimosa, ceiba, and the fig-tree, shaded and spread coolness along the banks of the lake. The plain, then thinly inhabited, was filled with brushwood, interspersed with trunks of scattered trees and parasite plants, enveloped with a thick sward, less capable of emitting radiant caloric than the soil that is cultivated and conse- quently not sheltered from the rays of the sun. With the destruction of the trees-1., and the increase of the cultivation of sugar, indigo, and cotton, the springs, and all the natural supplies of the lake of Valencia, have diminished from year to year. It is difficult to form a just idea of the enormous quantity of evaporation which takes place under the torrid zone, in a valley surrounded with steep declivities, where a regular breeze and descending currents of air are felt towards evening, and the bottom of which is flat, and looks as if levelled by the waters. It has been remarked, that the heat which prevails throughout the year at Cura, Guacara, Nueva Valencia, and on the borders of the lake, is the same as that felt at midsummer in Naples and Sicily. The mean annual temperature of the valleys of Aragua is nearly 25-5°; my hygrometrical observations of the month of February, taking the mean of day and night, gave 71'4° of the hair hygrometer. As the words great drought and great humidity have no determinate significa- tion, and air that would be called very dry in the lower regions of the tropics would be regarded as humid in Europe, we can judge of these relations between climates only by comparing spots situated in the same zone. Now at Cumana, where it sometimes does not rain during a whole year, and where I had the means of collecting a great number of hygrometric observations made at different hours of the day and night, the mean humidity of the air is 86°; corresponding to the mean temperature of 27'7°. Taking into account the influence of the rainy months, that is to say, estimating the difference observed in other part* MATE OF EVA.POHATIOir, ]\ of South America between the mean humidity of tin dry months and that of the whole year ; an annual mean hami- dity is obtained, for the valleys of Aragua, at farthest rjf 74?, the temperature being 25'5°. In this air, so hot, and at the same time so little humid, the quantity of water evaporated is enormous. The theory of Dalton estimates, under the conditions just stated, for the thickness of the sheet of water evaporated in an hour's time, 0*36 mill., or 3'8 lines in twenty-four hours. Assuming for the temperate zone, for instance at Paris, the mean temperature to be 10*6°, and the mean humidity 82°, we find, according to the same formula, 0*10 mill, an hour, and 1 line for twenty-four hours. If we prefer substituting for the uncertainty of these theoretical deductions the direct results of observa- tion, we may recollect that in Paris, and at Montmorency, the mean annual evaporation was found by Sedileau and Cotte, to be from 32 in. 1 line to 38 in. 4 lines. Two able engineers in the south of France, Messrs. Clausade and Pin, found, that in subtracting the effects of filtrations, the waters of the canal of Languedoc, and the basin of Saint Ferreol lose every year from 0'758 met. to 0*812 met., OP from 336 to 360 lines. M. de Prony found nearly similar results in the Pontine marshes. The whole of these experi- ments, made in the latitudes of 41° and 49°, and at 10'5° and 16° of mean temperature, indicate a mean evaporation of one line, or one and three-tenths a day. In the torrid zone, in the West India Islands for instance, the effect of evaporation is three times as much, according to Le Gaux, and double according to Cassan. At Cumana, in a place where the atmosphere is far more loaded with humi- dity than in the valley of Aragua, I have often seen evapo- rate during twelve hours, in the sun, 8*8 mill., in the shade 3*4 mill.; and 1 believe, that the annual produce of evapo- ration in the rivers near Cumana is not less than one hundred and thirty inches. Experiments of this kind are extremely delicate, but what I nave stated will suffice to demonstrate how great must be the quantity of vapour that rises from the lake of Valencia, and from the surrounding country, the waters of which flow into the lake. I shall have occasion elsewhere to resume this subject; for, in a work which displays the great laws of nature in different T2 ATMOSPHERIC MOISTURW zones, we must endeavour to solve the problem of tt e mean tension of the vapours contained in the atmosphere in dif- ferent latitudes, and at different heights above the surface of the ocean. A great number of local circumstances cause the produce of evaporation to vary ; it changes in proportion as more or less shade covers the basin of the waters, with their state of motion or repose, with their depth, and the nature and colour of their bottom ; but in general evaporation depends only on three circumstances, the temperature, the tension of the vapours contained in the atmosphere, and the resistance which the air, more or less dense, more or less agitated, opposes to the diffusion of vapour. The quantity of water that evaporates in a given spot, everything else being equal, is proportionate to the difference between the quantity of vapour which the ambient air can contain when saturated, and the quantity which it actually contains. Hence it follows that the evaporation is not so great in the torrid zone as might be expected from the enormous augmentation of temperature ; because, in those ardent climates, the air ia habitually very humid. Since the increase of agricultural industry in the valleys of Aragua, the little rivers which run into the lake of Valencia can no longer be regarded as positive supplies during the six months succeeding December. They remain dried up in the lower part of their course, because the planters of indigo, coffee, and sugar-canes, have made frequent drainings (azequias), in order to water the ground by trenches. AVe may observe also, that a pretty considerable river, the Kio Pao, which rises at the entrance of the Llanos, at the foot of the range of hills called La G-alera, heretofore mingled its waters with those of the lake, by uniting with the Cafio de Cambury, on the road from the town of Nueva Valencia to Gruigue. The course of this river was from south to north. At the end of the seventeenth century, the proprietor of a neighbouring plantation dug at the back of the hill a new bed for the Bio Pao. He turned the river; and, after having employed pirt of the water for the irrigation of hia fields, he caused the rest to flow at a venture southward, following the declivity of the Llanos. In this new southern direction the Kio Pao, mingled with three other rivers, the CHANGE OF IT VER-COUE8Eg. 13 Tinaco, the Guanarito, and the Chilua, falls into the Portu- guesa, which is a branch of the Apure. It is a remarkable phenomenon, that by a particular position of the ground, and the lowering of the ridge of division so south-west, the Kio Pao separates itself from the little system of interior rivers to which it originally belonged, and for a century past has communicated, through the channel of the Apure and the Orinoco, with the ocean. What has been nere effected on a small scale by the hand of man, nature often performs, either by progressively elevating the* level of the soil, or by those falls of the ground occasioned by violent earthquakes. It is probable, that in the lapse of ages, several rivers of Soudan, and of New Holland, which are now lost in the sands, or in inland basins, will open for themselves a course to the shores of the ocean. We cannot at least doubt, that in both continents there are systems of interior rivers, which may be considered as not entirely developed ; and which communicate with each other, either in the time of great risings, or by permanent bifurcations. The Rio Pao has scooped itself out a bed so deep and broad, that in the season of rains, when the Cano Grande de Cambury inundates all the land to the north-west of Guigue, the waters of this Cano, and those of the lake of Valencia, flow back into the Eio Pao itself; so that this river, instead of adding water to the lake, tends rather to carry it away. We see something similar in North America, where geo- graphers have represented on their maps an imaginary chain of mountains, between the great lakes of Canada and the country of the Miamis. At the time of floods, the waters flowing into the lakes communicate with those which run into the Mississippi; and it is practicable to proceed by boats from the sources of the river St. Marv to the Wabasli, as well as from the Chicago to the Illinois. These analo- gous facts appear to me well worthy of the attention 01 hydrographers. T»he land that surrounds the lake of Valencia being en- tirely flat and even, a diminution of a few inches in the level of the water exposes to view a vast extent of ground covered with fertile mud and organic remains.* In proportion aa the lake retires, cultivation advances towards the new shore. * This I observed daily in the Lake of Mtiico. 14 MBAN WATER-LEVEL. These natural desiccations, so important to agriculture, have been considerable durit % the last ten years, in which America has suffered from great droughts. Instead of mark- ing the sinuosities of the present banks of the lake, I have advised the rich landholders in these countries to fix columns of granite in the basin itself, in order to observe from year to year the mean height of the waters. The Marquis del Toro has undertaken to put this design into execution, employing the fine granite of the Sierra de Mariara, and establishing limnometers, on a bottom of gneiss rock, so common in the lake of Valencia. It is impossible to anticipate the limits, more or less narrow, to which this basin of water will one day be con- fined, when an equilibrium between the streams flowing in and the produce of evaporation and filtration, shall be com- pletely established. The idea very generally spread, that the lake will soon entirely disappear, seems to me chimerical. If in consequence of great earthquakes, or other causes equally mysterious, ten very humid years should succeed to long droughts; if the mountains should again become clothed with forests, and great trees overshadow the shore and the plains of Aragua, we should more probably see the volume of the waters augment, and menace that beautiful cultivation which now trenches on the basin of the lake. While some of the cultivators of the valleys of Aragua fear the total disappearance of the lake, and others its re- turn to the banks it has deserted, we hear the question gravely discussed at Caracas, whether it would not be advis- able, in order to give greater extent to agriculture, to conduct the waters of the lake into the Llanos, by digging a canal towards the Bio Pao. The possibility* of this enter- * The dividing ridge, namely, that which divides the waters between the valleys of Aragua and the Llanos, lowers so much towards the west of Guigue, as we have already observed, that there are ravines which conduct the waters of the Caflo de Cambury, the Rio Valencia, and the Guataparo, in the time of floods, to the Rio Pao ; but it would be easier to open a navigable canal from the lake of Valencia to the Orinoco, by the Pao, the Portuguesa, and the Apure, than to dig a draining canal level with the bottom of the lake. This bottom, according to the sounding, and my barometric measurements, is 40 toises less than 222, or 182 above the surface of the ocean. On the road from Guigue to the Llanos, by the table-land of La Villa de Cura, I found, to the south of the dividing ATEEAOE OF DEPTH. 15 prise cannot be denied, particularly ty havi'ig recourse to tunnels, or subterranean canals. The progressive retieat oi the waters has given birth to the beiutiful. and Itu.uriant plains of Maracay, Cura, Mocundo, GKiigue, and Santa Cruz del Escoval, planted wit1! tobacco, sugair-canes, coffee, indigo, and cacao ; but how can it be doubted for a momrnt that the lake alone spreads fertility over tiis country ? If de- prived of the enormous mass of vapOTir which th'j surface of the waters sends forth daily into i'ne s.;«:nosphere, the valleys of Aragua would become as dry and barren as the surrounding mountains. The mean depth of the lake is from twelve to fifteen fathoms ; the deepest parts are not, as is generally admitted, eighty, but thirty-five or forty deep. Such is the result of soundings made with the greatest care by Don Antonio Manzano. When we reflect on the vast depths of all the lakes of Switzerland, which, notwithstanding their position in high valleys, almost reach the level of the Mediterranean, it appears surprising that greater cavities are not found at the Dottom of the lake of Valencia, which is also an Alpine lake. The deepest places are between the rocky island of BUITO and the point of Cana Fistula, and opposite the high mountains of Mariara. But in general the southern part of the lake is deeper than the northern : nor must we forget that, if all the shores be now low, the southern part of the basin is the nearest to a chain of mountains with abrupt declivities ; and we know that even the sea is generally deepest where the coast is elevated, rocky, or perpendicular. The temperature of the lake at the surface during my abode in the valleys of Aragua, in the month of February, was constantly from 23° to 237°, consequently a little below the mean temperature of the air. This may be from the effect of evaporation, which carries off caloric from the air and the water ; or because a great mass of water does not follow with an equal rapidity the changes in the tempera- ridge, and on its southern declivity, no point of level corresponding to the 182 toises, except near San Juan. The absolute height of this village is 194 toisee. But.

I was not provided with the thermometrical sounding apparatus which I had used in the Alpine lakes of Salzburg, and in the Caribbean Sea. The experiments of Saussure prove that, on both sides of the Alps, the lakes which are from one hundred and ninety to two hundred and seventy-four toises of absolute elevation* have, in the middle of winter, at nine hundred, at six hundred, and sometimes even at one hundred and fifty feet of depth, a uniform temperature from 4'3 to 6 degrees : but these experiments have not yet been repeated in lakes situated under the torrid zone. The strata of cold water in Switzerland are of an enormous thickness. They have been found so near the surface in the lakes of Geneva and Bienne, that the decrement of heat in the water was one centesimal degree for ten or fifteen feet ; that is to say, eight times more rapid than in the ocean, and forty-eight times more rapid than in the atmosphere. In the temperate zone, where the heat of the atmosphere sinks to the freezing point, and far lower, the bottom of a lake, even were it not surrounded by glaciers and mountains covered with eternal snow, must contain particles of water which, having during winter acquired at the surface the maximum of their density, between 3'4° and 4*4°, have consequently fallen to the greatest depth. Other particles, the temperature of which is + 0'5°, far from placing themselves below the stratum at 4°, can only find their hydrostatic equilibrium above that stratum. They will descend lower only when their temperature is aug- mented 3° or 4° by the contact of strata less cold. If water in cooling continued to condense uniformly to the freezing point, there would be found, in very deep lakes and basins having no communication with each other (what- ever the latitude of the place), a stratum of water, the temperature of which would be nearly equal to the maxi- mum of refrigeration above the freezing point, which the lower regions of the ambient atmosphere annually attain. * This is the difference between the absolute elevations of the lakeg ot Geneva and Thun. •1 MEAN TEMPEHATUBE. IT Hence it is probable, that, in the plains of the torrid zone, or in the valleys but little elevated, the mean heat of which is from 25*5° to 27°, the temperature of the bottom of the lakes can never be below 21° or 22°. If in the same zone the ocean contain at depths of seven or eight hundred fathoms, water the temperature of which is at 7°, that is to say, twelve or thirteen degrees colder than the maximum of the heat* of the equinoctial atmosphere over the sea, I think it must be considered as a direct proof of a sub- marine current, carrying the waters of the pole towards the equator. We will not here solve the delicate problem, as to the manner in which, within the tropics and in the tem- perate zone, (for example, in the Caribbean Sea and in the lakes of Switzerland,) these inferior strata of water, cooled to 4° or 7°, act upon the temperature of the stony strata of the globe which they cover ; and how these same strata, the primitive temperature of which is, within the tropics, 27°, and at the lake of Q-eneva 10°, react upon the half-frozen waters at the bottom of the lakes, and of the equinoctial ocean. These questions are of the highest importance, both with regard to the economy of animals that live habitually at the bottom of fresh and salt waters, and to the theory of the distribution of heat in lands surrounded by vast and deep seas. The lake of Valencia is full of islands, which embellish the scenery by the picturesque form of their rocks, and the beauty of the vegetation with which they are covered : an advantage which this tropical lake possesses over those of the Alps. The islands are fifteen in number, distributed in three groups ;t without reckoning Morro and Cabrera, which are already joined to the shore. They are partly * It is almost superfluous to observe that I am considering here only that part of the atmosphere lying on the ocean between 10° north and 10* south latitude. Towards the northern limits of the torrid zone, in latitude 23°, whither the north winds bring with an extreme rapidity the cold air of Canada, the thermometer falls at sea as low as 16°, and even lower. f The position of these islands is as follows : northward, near the shore, the Isla de Cura ; on the south-east, Burro, Homo, Otama, Sorro, Caiguira, Nuevos Peflones, or the Aparecidos ; on the north-west, Cabo Blanco, o\ Isla de Aves, and Chamberg ; on the south-west, Brucha and Culebra. In the centre of the lake rise, like shoals or small detached rocka, Vagre, Fraile, Peflasco, and Pan de Azucar. VOL. II. 0 18 INHABITANTS OF THE ISLANDS. cultivated, and extremely fertile on account of the vapours that rise from the lake. Burro, the largest of these islands, is two miles in length, and is inhabited by some families of mestizos, who rear goats. These simple people seldom visit the shore of Mocundo. To them the lake appears of immense extent ; they have plantains, cassava, milk, and a little fish. A hut constructed of reeds ; hammocks woven from the cotton which the neighbouring fields produce ; a large stone on which the fire is made ; the ligneous fruit of the tutuma (the calabash) in which they draw water, con- stitute their domestic establishment. An old mestizo who offered us some goat's milk had a beautiful daughter. "We learned from our guide, that solitude had rendered him as mistrustful as he might perhaps have been made by the society of men. The day before our arrival, some hunters had visited the island. They were overtaken by the shades of night ; and preferred sleeping in the open air to return- ing to Mocundo. This news spread alarm throughout the island. The father obliged the young girl to climb up a very lofty zamang or acacia, which grew in the plain at some distance from the hut, while he stretched himself at the foot of the tree, and did not permit his daughter to descend till the hunters had departed. The lake is in general well stocked with fish ; though it furnishes only three kinds, the flesh of which is soft and insipid, the guavina, the vagre, and the sardina. The two last descend into the lake with the streams that flow into it. The guavina, of which I made a drawing on the spot, is 20 inches long and 3'5 broad. It is perhaps a new species of the genus erythrina of Gronovius. It has large silvery scales edged with green. This fish is extremely voracious, and destroys other kinds. The fishermen as- sured us that a small crocodile, the lava* which often approached us when we were bathing, contributes also to the destruction of the fish. We never could succeed in pro- curing this reptile so as to examine it closely : it generally * The bava, or bavilla, is very common at Bordones, near Cumana. See vol. i, p. 160. The name of bava (baveuse) has misled M. Depons; he takes this reptile for a fish of our seas, the Blennius pholis. (Voyage a la Terre Ferme.) The Blennius pholis (smooth blenny), is called by the French baveuse (slaverer), in Spanish, baba. CROCODILES. 19 attaint only three or four feet in length. It is said to be very harmless ; its habits however, as well as its form, much resemble those of the alh'gator (Crocodilus acutus). It swims in such a manner as to show only the point of its snout, and the extremity of its tail ; and places itself at mid-day on the bare beach. It is certainly neither a monitor (the real monitors living only in the old continent,) nor the sauvegarde of Seba (Lacerta teguixin,) which dives and does not swim. It is somewhat remarkable that the lake of Valencia, and the whole system of small rivers flowing into it, have no large alligators, though this dan- gerous animal abounds a few leagues off in the streams that flow either into the Apure or the Orinoco, or imme- diately into the Caribbean Sea between Porto Cabello and La Guayra. In the islands that rise like bastions in the midst of the waters, and wherever the rocky bottom of the lake is visible, I recognised a uniform direction in the strata of gneiss. This direction is nearly that of the chains of mountains 011 the north and south of the lake. In the hills of Cabo Blanco there are found among the gneiss, angular masses of opaque quartz, slightly translucid on the edges, and vary- ing from grey to deep black. This quartz passes sometimes into hornstein, and sometimes into kieselschiefer (schistose jasper). I do not think it constitutes a vein. The waters of the lake* decompose the gneiss by erosion in a very extraordinary manner. I have found parts of it porous, almost cellular, and split in the form of cauliflowers, fixed on gneiss perfectly compact. Perhaps the action ceases with the movement of the waves, and the alternate contact of air and water. The island of Chamberg is remarkable for its height. It is a rock of gneiss, with two sumimiti in the form of a saddle, and raised two hundred feet above the surface of the water. The slope of this rock is barren, and affords only nourishment for a few plants of clusia with large white * The water of the lake is not salt, as is asserted at Caracas. It may be drunk without being filtered. On evaporation it leaves a very small residuum of carbonate of lime, and perhaps a little nitrate of potash.

But the view of the lake and of the richly culti- vated neighbouring valleys is beautiful, and their aspect is wonderful after sunset, when thousands of aquatic birds, herons, flamingoes, and wild ducks cross the lake to roost in the islands, and the broad zone of mountains wrhich surrounds the horizon is covered with fire. The inhabitants, as we have already mentioned, burn the meadows in order to produce fresher and finer grass. Gramineous plants abound, especially at the summit of the chain ; and those vast conflagrations extend sometimes the length of a thou- sand toises, and appear like streams of lava overflowing the ridge of the mountains. When reposing on the banks of the lake to enjoy the soft freshness of the air in one of those beautiful evenings peculiar to the tropics, it is delight- ful to contemplate in the waves as they beat the shore, the reflection of the red fires that illumine the horizon. Among the plants which grow on the rocky islands of the iake of Valencia, many have been believed to be peculiar to those spots, because till now they have not been dis- covered elsewhere. Such are the papaw-trees of the lake ; and the tomato* of the island of Cura. The latter differs from our Solanum lycopersicum ; the fruit is round and small, but has a fine flavour ; it is now cultivated at La Victoria, at Nueva Valencia, and everywhere in the valleys of Aragua. The papaw-tree of the lake (papaya de la laguna) abounds also in the island of Cura and at Cabo Blanco ; its trunk shoots higher than that of the common papaw (Carica papaya), but its fruit is only half as large, perfectly spherical, without projecting ribs, and four or five inches in diameter. "When cut open it is found quite filled with seeds, and without those hollow places which occur constantly in the common papaw. The taste of this fruit, of which I have often eaten, is extremely sweet.f I know not whether it be a variety of the Carica microcarpa, de- scribed by Jaequin. The environs of the iake are insalubrious only in times of great drought, when the waters in their retreat leave a * The tomatos are cultivated, as well as the papaw-tree of the lake, in the Botanical Garden of Berlin, to which I had sent some seeds. f The people of the country attribute to it an astringent quality, and call it tapaculo. HOT SPRINGS OP THE LAKE. 21 muddy sediment exposed to the rays of the sun. The banks, shaded by tufts of Coccoloba barbadensis, and decorated with fine liliaceous plants,* remind us, by the appearance of the aquatic vegetation, of the marshy shores of our lakes in Europe. We find there, pondweed (pota- mogeton), chara, and cats'-tail three feet high, which it is difficult not to confound with the Typha angustifolia of our marshes. It is only after a careful examination, that we recognise each of these plants for distinct species,f peculiar to the new continent. How many plants of the Straits of Magellan, of Chile, and the Cordilleras of Quito have formerly been confounded with the productions of the northern temperate zone, owing to their analogy in form and appearance. The inhabitants of the valleys of Aragua often inquire why the southern shore of the lake, particularly the south- west part towards los Aguacotis, is generally more shaded, and exhibits fresher verdure than the northern side. We saw, in the month of February, many trees stripped of their foliage, near the Hacienda de Cura, at Mocundo, and at Guacara ; while to the south-east of Valencia everything presaged the approach of the rains. I believe that in the early part of the year, when the sun has southern declina- tion, the hills around Valencia, Guacara, and Cura are scorched by the heat of the solar rays, while the southern shore receives, along with the breeze when it enters the valley by the Abra de Porto Cabello, an atmosphere which has crossed the lake, and is loaded with aqueous vapour. On this southern shore, near Gruaruto, are situated the finest plantations of tobacco in the whole province. Among the rivers flowing into the lake of Valencia some owe their origin to thermal springs, and deserve particular .•ittention. These springs gusn out at three points of the granitic Cordillera of the coaat ; near Onoto, oetween Tur- niero and Maracay; near Mariara, north-east of the Hacienda de Cura ; and near Las Trincheras, on the road from Nueva Valencia to Porto Cabello. I could examine with care only the physical and geological relations of the thermal waters of Mariara and Las Trincheras. In going up the small river • Pancratium undulatum, Amaryllis nervosa. t Potaraogeton tenuifolium, Chara conipressa, Typha tenuifoli*. 22 EIO DE AQUAS CALIENTES. Cura towards its source, the mountains of Mariara are seen advancing into the plain in the form of a vast amphitheatre, composed of perpendicular rocks, crowned by peaks with rugged summits. The central point of the amphitheatre bears the strange name of the Devil's Nook (Eincon del Diablo). The range stretching to the east is called El Chaparro ; that to the west, Las Viruelas. These ruin-like rocks command the plain ; they are composed of a coarse- grained granite, nearly porphyritic, the yellowish white feld- spar crystals of which are more than an inch and a half long. Mica is rare in them, and is of a fine silvery lustre. Nothing can be more picturesque and solemn than the aspect of this group of mountains, half covered with vegetation. The Peak of Calavera, which unites the Eincon del Diablo to the Chaparro, is visible from afar. In it the granite is separated by perpendicular fissures into prismatic masses. It would seem as if the primitive rock were crowned with columns of basalt. In the rainy season, a considerable sheet of water rushes down like a cascade from these cliffs. The moun- tains connected on the east with the Eincon del Diablo, are much less lofty, and contain, like the promontory of La Cabrera, and the little detached hills in the plain, gneiss and mica-slate, including garnets. In these lower mountains, two or three miles north-east of Mariara, we find the ravine of hot waters called Que- brada de Aguas Calientes. This ravine, running JN".W. 75°, contains several small basins. Of these the two uppermost, which have no communication with each other, are only eight inches in diameter ; the three lower, from two to three feet. Their depth varies from three to fifteen inches. The temperature of these different funnels (pozos) is from 56° to 59° ; and what is remarkable, the lower funnels are hotter than the upper, though the difference of the level is only seven or eight inches. The hot waters, collected together, form a little rivulet, called the Eio de Aguas Calientes, which, thirty feet lower, has a temperature of only 48°. In seasons of great drought, the time at which we visited the ravine, the whole body of the thermal waters forms a section of only twenty-six square inches. This is considerably augmented in the rainy season ; the rivulet is then transformed into a torrent, and its heat SULPHUREOUS SPRINGS. 23 for it appears that the hot springs themselves are subject only to imperceptible variations. All these springs are slightly impregnated with sulphuretted hydrogen gas. The fetid smell, peculiar to this gas, can be perceived only by approaching very near the springs. In one of these wells only, the temperature of which is 56*2°, bubbles of air are evolved at nearly regular intervals of two or three minutes. I observed that these bubbles constantly rose from the same points, which are four in number ; and that it was not pos- sible to change the places from which the gas is emitted, by stirring the bottom of the basin with a stick. These places correspond no doubt to holes or fissures on the gneiss ; and indeed when the bubbles rise from one of the apertures, the emission of gas follows instantly from the other three. I could not succeed in inflaming the small quantities of gas that rise above the thermal waters, or those I collected in a glass phial held over the springs, an operation that ex- cited in me a nausea, caused less by the smell of the gas, than by the excessive heat prevailing in this ravine. Is this sulphuretted hydrogen mixed with a great proportion of car- bonic acid or atmospheric air? I am doubttul of the first of these mixtures, though so common in thermal waters ; for example at Aix la Chapelle, Enghien, and Bareges. The gas collected in the tube of Fontana's eudiometer had been shaken for a long time with water. The small basins are covered with a light film of sulphur, deposited by the sul- phuretted hydrogen in its slow combustion in contact with the atmospheric oxygen. A few plants near the springs were incrusted with sulphur. This deposit is scarcely visible when the water of Mariara is suffered to cool in aii open vessel ; no doubt because the quantity of disengaged gas is very small, and is not renewed. The water, when cold, gives no precipitate with a solution of nitrate of copper; it is destitute of flavour, and very drinkable. If it contain any saline substances, for example, the sulphates of soda or magnesia, their quantities must oe very insignificant.

Fourcroy and Vauquelin, by the way of Poriio Cabello and the Havannah. This purity in hot waters issuing immediately from granite mountains is in Europe, as well as in the New Continent, a most curious phenomenon.* How can we explain the origin of the sulphuretted hydrogen? It cannot proceed from the de- composition of sulphurets of iron, or pyritic strata. Is it owing to sulphurets of calcium, of magnesium, or other earthy metalloids, contained in the interior of our planet, under its rocky and oxidated crust ? In the ravine of the hot waters of Mariara, amidst little funnels, the temperature of which rises from 56° to 59°, two species of aquatic plants vegetate ; the one is membrana- ceous, and contains bubbles of air; the other has parallel fibres. The first much resembles the Ulva labyrinthiformis of Vandelli, which the thermal waters of Europe furnish. At the island of Amsterdam, tufts of lycopodium and mar- chantia have been seen in places where the heat of the soil was far greater : such is the effect of an habitual stimulus on the organs of plants. The waters of Mariara contain no aquatic insects. Erogs are found in them, which, being probably chased by serpents, have leaped into the funnels, and there perished. South of the ravine, in the plain extending towards the shore of the lake, another sulphureous spring gushes out, less hot and less impregnated with gas. The crevice whence this water issues is six toises higher than the funnel just described. The thermometer did not rise in the crevice above 42°. The water is collected in a basin surrounded by large trees ; it is nearly circular, from fifteen to eighteen feet diameter, and three feet deep. The slaves throw themselves into this bath at the end of the day, when covered with dust, after having worked in the neighbouring fields of in- digo and sugar-cane. Though the water of this bath (bano) is habitually from 12° to 14° hotter than the air, the negroes call it refreshing ; because in the torrid zone this term is * Warm springs equally pure are found issuing from the granites of Portugal, and those of Cantal.

THE VOLADOE. 25 used for whatever restores strength, calms the irritation of the nerves, or causes a feeling of comfort. We ourselves ex- perienced the salutary effects of the bath. Having slung our hammocks on the trees round the basin, we passed a whole day in this charming spot, which abounds in plants. We found near the baiio of Mariara the volador, or gyrocarpus. The winged fruits of this large tree turn like a fly-wheel, when they fall from the stalk. On shaking the branches of the volad&r, we saw the air filled with its fruits, the simul- taneous fall of winch presents the most singular spectacle. The two membranaceous and striated wings are turned so as to meet the air, in falling, at an angle of 45°. Fortu- nately the fruits we gathered were at their maturity. We sent some to Europe, and they have germinated in the gardens of Berlin, Paris, and Malmaison. The numerous plants of the volador, now seen in hot-houses, owe their origin to the only tree of the kind found near Mariara. The geographical distribution of the different species of gyro- carpus, which Mr. Brown considers as one of the laurinese, is very singular. Jacquin saw one species near Carthagena in America.* This is the same which we met with again in Mexico, near Zumpango, on the road from Acapulco to the capital.f Another species, which grows on the moun- tains of Coromandel.J has been described by Koxburgh: the third and fourth § grow in the southern hemisphere, oil the coasts of A ustralia. After getting out of the bath, while, half-wrapped in a sheet, we were drying ourselves in the sun, according to the custom of the country, a little man of the mulatto race approached us. After bowing gravely, he made us a long speech on the virtues of the waters of Mariara, adverting to the numbers of invalids by whom they have been visited for some years past, and to the favourable situation of the springs, between the two towns Valencia and Caracas. He * The Gyrocarpus Jacquini of Gartner, or Gyrocarpus ameiicanus of Willdenow. t The natives of Mexico called it gmtlacocffi.

He assured us that we should there find all the conveniences of life ; nails to suspend our hammocks, ox-leather to stretch over benches made of reeds, earthern vases always filled with cool water, and what, after the bath, would be most salutary of all, those great lizards (iguanas), the flesh of which is known to be a refreshing aliment. "We judged from his harangue, that this good man took us for invalids, who had come to stay near the spring. His counsels and offers of hospitality were not altogether disinterested. He styled himself ' the inspector of the waters, and the pulpero* of the place.' Accordingly all his obliging attentions to us ceased as soon as he heard that we had come merely to satisfy our curi- osity; or as they express it in the Spanish colonies, those lands of idleness, para ver, no mas, ' to see, and nothing more.' The waters of Mariara are used with success in rheumatic swellings, and affections of the skin. As the waters are but very feebly impregnated with sulphuretted hydrogen, it is necessary to bathe at the spot Where the springs issue. Farther on, these same waters are employed for the irrigation of fields of indigo. A wealthy landed proprietor of Mariara, Don Domingo Tovar, had formed the project of erecting a bathing-house, and an establish- ment which would furnish visitors with better resources than lizard's flesh for food, and leather stretched on a bench for their repose. On the 21st of February, in the evening, we set out from the beautiful Hacienda de Cura for Gruacara and Nueva Valencia. We preferred travelling by night, on account of the excessive heat of the day. We passed by the hamlet of Punta Zamuro, at the foot of the high mountains of Las Viruelas. The road is bordered with large zamang-trees, or mimosas, the trunks of which rise to sixty feet high. Their branches, nearly horizontal, meet at more than one hundred and fifty feet distance. I have nowhere seen a vault of verdure more beautiful and luxuriant.

The negro who conducted us uttered wild cries, xpecting by these means to frighten the tiger; but his ftbrts were ineffectual. The jaguar, like the wolf of Europe, follows travellers even when he will not attack them; the wolf in the open fields and in unsheltered places, the jaguar skirting the road and appearing only at intervals between the bushes. We passed the day on the 23rd in the house of the Marquis de Toro, at the village of Gruacara, a very con- siderable Indian community. An avenue of carolineas leads from Gruacara to Mocundo. It was the first time I had seen in the open air this majestic plant, which forms one of the principal ornaments of the extensive conservatories of Schonbrunn.* Mocundo is a rich plantation of sugar- canes, belonging to the family of Toro. "We there find, what is so rare in that country, a garden, artificial clumps of trees, and on the border of the water, upon a rock of gneiss, a pavilion with a mirador, or belvidere. The view is delightful over the western part of the lake, the surround- ing mountains, and a forest of palm-trees that separates Guacara from the city of Nueva Valencia. The fields of sugar-cane, from the soft verdure of the young reeds, re- semble a vast meadow. Everything denotes abundance; but it is at the price of the liberty of the cultivators.

Creole cane and the cane of Otaheite* are planted in the month of April, the first at four, the second at five feet distance. The cane ripens in tourteen months. It flowers in the month of October, if the plant be sufficiently vigo- rous; but the top is cut off before the panicle unfolds. In all the monocotvledonous plants (for example, the ma- guey cultivated at Mexico for extracting pulque, the wine- yielding palm-tree, and the sugar-cane), the flowering alters the quality of the juices. The preparation of sugar, the boiling, and the claying, are very imperfect in Terra Firma, because it is made only for home consumption; and for wholesale, papelon is preferred to sugar, either refined or raw. This papelon is an impure sugar, in the form of little loaves, of a yellow-brown colour. It contains a mixture of molasses and mucilaginous matter. The poorest man eats papelon, as in Europe he eats cheese. It is believed to have nutritive qualities. Fermented with water it yields the guarapo, the favourite beverage of the people. In the pro- vince of Caracas subcarbonate of potash is used, instead of lime, to purify the juice of the sugar-cane. The ashes of the bucare, which is the Erythrina corallodendnim, are pre- ferred. The sugar-cane \vas introduced very late, probably towards the end of the sixteenth century, from the West India Islands, into the valleys of Aragua. It was known in India, in China, and in all the islands of the Pacific, from the most remote antiquity; and it was planted at Khorassan, in Persia, as early as the fifth century of our era, in order to obtain from it solid sugar.f The Arabs carried this reed, so useful to the inhabitants of hot and temperate countries, to the shores of the Mediterranean. In 1306, its culti- vation was yet unknown in Sicily; but was already common in the island of Cyprus, at Rhodes, and in the Morea. A hundred years after it enriched Calabria, Sicily, and the coasts of Spain. From Sicily the Infante Don Henry trans- * In the island of Palma, where in the latitude of 29° the sugar-cane is said to be cultivated as high as 140 toises above the level of the Atlantic, the Otaheite cane requires more heat than the Creole cane. t The Indian name for the sugar-cane is sharkara. Thence the word MANUFACTURE OF SUOAB. 29 planted the cane to Madeira: from Madeira it passed to the Canary Islands, where it was entirely unknown; for the ' ferulae' of Juba, ' quse express® liquorem fundunt potui ucundum,' are euphorbias (the Tabayba dulce), and not, as has been recently asserted,* sugar-canes. Twelve sugar- manufactories (ingenios de azucar) were soon established ji the island of Great Canary, in that of Palma, and between Adexe, Icod, and Guarachico, in the island of Tenerifte. Negroes were employed in this cultivation, and their de- scendants still inhabit the grottos of Tiraxaua, in the Great Canary. Since the sugar-cane has been transplanted to the West Indies, and the New "World has given maize to the Canaries, the cultivation of the latter has taken the place of the cane at Tenerifte and the Great Canary. The cane is now found only in the island of Palma, near Argual and Tazacorte,f where it yields scarcely one thousand quin- tals of sugar a year. The sugar-cane of the Canaries, which Aiguilon transported to St. Domingo, was there cultivated extensively as early as 1513, or during the six or seven following years, under the auspices of the monks of St. Jerome. Negroes were employed in this cultivation from its commencement ; and in 1519 representations were made to government, as in our own time, that the West India Islands would be ruined and made desert, if slaves were not conveyed thither annually from the coast of Guinea. For some years past the culture and preparation of sugar has been much improved in Terra Firma ; and, as the pro- cess of refining is prohibited by the laws at Jamaica, they reckon on the fraudulent exportation of refined sugar to the English colonies. But the consumption of the pro- vinces of Venezuela, in papelon, and in raw sugar employed in making chocolate and sweetmeats (dulces) is so enor- mous, that the exportation has been hitherto entirely null. The finest plantations of sugar are in the valleys of Aragua and of the Tuy, near Pao de Zarate, between La Victoria • On the origin of cane-sugar, in the Journal de Pharmacie, 1816, p. 387.

Amidst the great number of curious phenomena which I have observed in the course of my travels, I confess there are few that have made BO powerful an impression on me as the aspect of the cow-tree. Whatever relates to milk or to corn, inspires an interest which is not merely that of the physical knowledge of things, but is connected with another order of ideas and sentiments. We can scarcely conceive how the human race could exist without farina- ceous substances, and without that nourishing juice which the breast of the mother contains, and which is appro- priated to the long feebleness of the infant. The amy- laceous matter of corn, the object of religious veneration among so many nations, ancient and modern, is diffused in the seeds, and deposited in the roots of vegetables ; milk, which serves as an aliment, appears to us exclusively the produce of animal organization. Such are the impressions we have received in our earliest infancy : such is also the source of that astonishment created by the aspect of the tree just described. It is not here the solemn shades of forests, the majestic course of rivers, the mountains wrapped in eternal snow, that excite our emotion. A few drops of vegetable juice recall to our minds all the power- fulness and the fecundity of nature. On the barren flank of a rock grows a tree with coriaceous and dry leaves. Its large woody roots can scarcely penetrate into the stone. For several months of the year not a single shower moistens its foliage. Its branches appear dead and dried ; but when the trunk is pierced there flows from it a sweet and nourish- ing milk. It is at the rising of the sun that this vegetable fountain is most abundant. The negroes and natives are then seen hastening from all quarters, furnished with large bowls to receive the milk, which grows yellow, and thickens at its surface. Some empty their bowls under the tree itself, others carry the juice home to their children. marked by Spanish writers that there are some which pour out a milky juice which soon grows solid, like gum, affording a pleasant odour; and also others that give out a liquid which coagulates like cheese, and which they eat at meals without any ill effects).

B 50 ALIMENTARY PROPERTIES OF TREES- ID examining the physical properties of animal and vege- table products, science displays them as closely linked together ; but it strips them of what is marvellous, and perhaps, therefore, of a part of their charms. Nothing appears isolated ; the chemical principles that were believed to be peculiar to animals are found in plants ; a common chain links together all organic nature. Long before chemists had recognized small portions of wax in the pollen of flowers, the varnish of leaves, and the whitish dust of our plums and grapes, the inhabitants of the Anctes of Quindiu made tapers with the thick layer of wax that covers the trunk of a palm-tree.* It is but a few year? since we discovered, in Europe, caseum, the basis of cheese, in the emulsion of almonds ; yet for ages past, in the mountains of the coast of Venezuela, the milk of a tree, and Vhe cheese separated from that vegetable milk, have beeii considered as a salutary aliment. How are we to account for this singular course in the development of knowledge? How have the unlearned inhabitants of one hendsphere become cognizant of a fact which, in the other, so long escaped the sagacity of the scientific ? It is because a small number of elements and principles differently com- bined are spread through several families of plants ; it is because the genera and species of these natural families are not equally distributed in the torrid, the frigid, and the temperate zones; it is that tribes, excited by want, and deriving almost all their subsistence from the vegetable kingdom, discover nutritive principles, farinaceous and ali- mentary substances, wherever nature has deposited them in the sap, the bark, the roots, or the fruits of vegetables. That amylaceous fecula which the seeds of the cereal plants furnish in all its purity, is found united with an acrid and sometimes even poisonous juice, in the roots of the arums, the Tacca pinnatifida, and the Jatropha manihot. The savage of America, like the savage of the South Sea islands, has learned to dulcify the fecula, by pressing and separating it from its juice. In the milk of plants, and in the milky emulsions, matter extremely nourishing, albumen, caseum, and sugar, are found mixed with caoutchouc and with deleterious and caustic principles, such as nurphine * Coroxylon andicola. MILK-PRODUCING PLANTS. 51 and hydrocyanic acid.* These mixtures vary not only in the different families, but also in the species which belong to the same genus. Sometimes it is morphine or the nar- cotic principle, that characterises the vegetable milk, as in some papaverous plants ; sometimes it is caoutchouc, as in the hevea and the castilloa ; sometimes albumen and caseum, as in the cow-tree. The lactescent plants belong chiefly to the three families of the euphorbiaceae, the urticea?, and the apocineffif. Since, on examining the distribution of vegetable forms over the globe, we find that those three families are more nume- rous in species in the low regions of the tropics, we must thence conclude, that a very elevated temperature contri- butes to the elaboration of the milky juices, to the formation of caoutchouc, albumen, and caseous matter. The sap of the palo de vaca furnishes unquestionably the most striking example of a vegetable milk in which the acrid and de- leterious principle is not united with albumen, caseum, and caoutchouc : the genera euphorbia and asclepias, how- ever, though generally known lor their caustic properties, already present us with a few species, the juice of which is sweet and harmless. Such are the Tabayba dulce of the Canary Islands, which we have already mentioned,^ and the Asclepias lactifera of Ceylon. Burman relates that, in the latter country, when cow's milk is wanting, the milk of this asclepias is used; and that the aliments commonly pre- pared with animal milk are boiled with its leaves. It may be possible, as Decandolle has well observed, that the natives employ only the juice that flows from the young plant, at a period when the acrid principle is not yet deve- loped. In fact, the first shoots of the apocyneous plants are eaten in several countries. * Opium contains morphine, caoutchouc, &c. t After these three great families follow the papaveracese, the chico- raceae, the lobeliacese, the campanulaceae, the sapoteae, and the cucurbi- taceoe. The hydrocyanic acid is peculiar to the group of rosaceo-amyg- dalacese. In the monocotyledonous plants there is no milky juice ; but the perisperm of the palms, which yields such sweet and agreeable milky emulsions, contains, no doubt, caseum. Of what nature is the milk of mushrooms ? t Euphorbia balsamifera. The milky juice of the Cactus mannllaris if equally *wert. x 2 62 ANALYSTS OF VEGETABLE MILK I have endeavoured by these comparisons to bring into consideration, under a more general point of view, the milky juices that circulate in vegetables ; and the milky emulsions that the fruits of the amygdalaceous plants and palms yield. I may be permitted to add the result of some experiments which I attempted to make on the juice of the Carica papaya during my stay in the valleys of Aragua, though I was then almost destitute of chemical tests. The juice has been since examined by Vauquelin, and this celebrated chemist has very clearly recognized the albumen and caseous matter ; he compares the milky sap to a substance strongly animalized, — to the blood of animals; but his researches were confined to a fermented juice and a coagulum of a foetid smell, formed during the passage from the Mauritius to France. He has expressed a wish that some traveller would examine the milk of the papaw-tree just as it flows from the stem or the fruit. The younger the fruit of the carica, the more milk it yields : it is even found in the germen scarcely fecundated. In proportion as the fruit ripens, the milk becomes less abun- dant, and more aqueous. Less of that animal matter which is coagulable by acids and by the absorption of atmospheric oxygen, is found in it. As the whole fruit is viscous,* it might be supposed that, as it grows larger, the coagulable matter is deposed in the organs, and forms a part of the pulp, or the ileshy substance. When nitric acid, diluted with four parts of water, is added drop by drop to the milk expressed from a very young fruit, a very extraordinary phe- nomenon appears. At the centre of each drop a gelatinous pellicle is formed, divided by greyish streaks. These streaks are simply the juice rendered more aqueous, owing to the contact of the acid having deprived it of the albumen. At the same time, the centre of the pellicles becomes opaque, and of the colour of the yolk of an egg ; they enlarge as if by the prolongation of divergent fibres. The whole liquid " The same viscosity is also remarked in the fresh milk of the palo de vaca. It is no doubt occasioned by the caoutchouc, which ii not yet separated, and which forms one mass with the albumen and the caseum, as the butter and the caseum in amimal milk. The juice of a enphorbiaceous plant (Sapium aucuparium), which also yields caoutchouc U so glutinous that it is used to catch parrots. ANALYSIS OF VEGETABLE MILK. 08 assumes at first the appearance of an agate with milky clouds ; and it seems as if organic membranes were forming under the eye of the observer. When the coagulum extends to the whole mass, the yellow spots again disappear. By agitation it becomes granulous like soft cheese.* The yellow colour reappears on adding a few more drops of nitric acid. The acid acts in this instance as the oxygen of the atmosphere at a temperature from 27° to 35° ; for the white coagulum grows yellow in two or three minutes, when exposed to the sun. After a few hours the yellow colour turns to brown, no doubt because the carbon is set more free progressively as the hydrogen, with which it was com- bined, is burnt. The coagulum formed by the acid becomes viscous, and acquires that smell of wax which I have observed in treating muscular flesh and mushrooms (morels) with nitric acid. According to the fine experiments of Mr. Hatchett, the albumen may be supposed to pass partly to the state of gelatine. The coagulum of the papaw-tree, when newly prepared, being thrown into water, softens, dis- solves in part, and gives a yellowish tint to the fluid. The milk, placed in contact with water only, forms also mem- branes. In an instant a tremulous jelly is precipitated, resembling starch. This phenomenon is particularly striking if the water employed be heated to 40° or 60°. The jelly condenses in proportion as more water is poured upon it. It preserves a long time its whiteness, only growing yellow by the contact of a few drops of nitric acid. Guided by the experiments of Fourcroy and Vauquelin on the juice of the * The substance which falls down in grumous and filamentous clots is not pure caoutchouc, but perhaps a mixture of this substance with caseum and albumen. Acids precipitate the caoutchouc from the milky juice of the euphorbiums, fig-trees, and hevea; they precipitate the caseum from the milk of animals. A white coagulum was formed hi phials closely stopped, containing the milk of the hevea, and preserved among our col- lections, during our journey to the Orinoco. It is perhaps the develop- ment of a vegetable acid which then furnishes oxygen to the albumen. Th6 formation of the coagulum of the hevea, or of real caoutchouc, is nevertheless much more rapid in contact with the air. The absorption of atmospheric oxygen is not in the least necessary to the production of butter which exists already formed in the milk of animals ; but I believe it cannot be doubted that, in the milk of plants, this absorption produces the pellicles of caoutchouc, of coagulated albumen, and of caseum, which we successively formed in vessels exposed to the open air. 64i ANIMAL AND TEGETABLE MILK. hevea, I mixed a solution of carbonate of soda with the milk of the papaw. No clot ig formed, even when pure water is poured on a mixture of the milk with the alkaline solution. The membranes appear only when, by adding an acid, the soda is neutralized, and the acid is in excess. I made the coagulum formed by nitric acid, the juice of lemons, or hot water, likewise disappear by mixing it with carbonate of soda. The sap again becomes milky and liquid, as in its primitive state ; but this experiment succeeds only when the coagulum has been recently formed. On comparing the milky juices of the papaw, the cow-tree, and the hevea, there appears a striking analogy between the juices which abound in caseous matter, and those in which caoutchouc prevails. All the white and newly prepared caoutchouc, as well as the waterproof cloaks, manufactured in Spanish America by placing a layer of milk of hevea between two pieces of cloth, exhale an animal and nauseat- ing smell. This seems to indicate that the caoutchouc, in coagulating, carries with it the caseum, which is perhaps only an altered albumen. The produce of the bread-fruit tree can no more be considered as bread than plantains before the state of maturity, or the tuberous and amylaceous roots of the cas- sava, the dioscorea, the Convolvulus batatas, and the potato. The milk of the cow-tree contains, on the contrary, a caseous matter, like the milk of mammiferous animals. Advancing to more general considerations, we may regard, with M. Gay-Lussac, the caoutchouc as the oily part, — the butter of vegetable milk. We find in the milk of plants caseum and caoutchouc; in the milk of animals, caseum and butter. The proportions of the two albuminous and oily principles differ in the various species of animals and of lactescent plants. In these last they are most fre- quently mixed with other substances hurtful as food ; but of which the separation might perhaps be obtained by chemical processes. A vegetable milk becomes nourishing when it is destitute of acrid and narcotic principles ; and abounds less in caoutchouc than in caseous matter.* * The milk of the lactescent agarics has not been separately analysed ; it contains an acrid principle in the Agaricus piperatus ? and in other •pecies it is sweet and harmless. The experiments of MM. Braconnofc, THE BUTTEH TEEB. 55 Whilst the polo de vaca manifests the immense fecundity and the bounty of nature in the torrid zone, it also reminds us of the numerous causes which favour in those fine climates the careless indolence of man. Mungo Park has made known the butter-tree of Bambarra, which M. De Candolle suspects to be of the family of sapotas, as well as our milk-tree. The plantain, the sago-tree, and the mauritia of the Orinoco, are as much bread-trees as the rema of the South Sea. The fruits of the crescentia and the lecythis serve as vessels for containing food, while the spathes of the palms, and the bark of trees, furnish caps and garments without a seam. The knots, or rather the interior cells of Bouillon-Lagrange, and Vauquelin (Annales de Chimie, vol. xlvi, vol. li, vol. Ixxix, vol. Ixxx, vol. Ixxxv, have pointed out a great quantity of al- bumen in the substance of the Agaricus deliciosus, an edible mushroom. It is this albumen contained in their juice which renders them so hard when boiled. It has been proved that morels (Morchella esculenta) can be con- verted into sebaceous and adipocerous matter, capable of being used in the fabrication of soap. (De Candolle, sur les Proprietes medicinales des Plantes.) Saccharine matter has also been found in mushrooms by Gun- ther. It is in the family of the fungi, more especially in the clavariae, phalli, helvetise, the merulii, and the small gymnopae which display themselves in a few hours after a storm of rain, that organic nature produces with most rapidity the greatest variety of chemical principles — sugar, albumen, adipocire, acetate of potash, fat, ozmazome, the aromatic principles, &c. It would be interesting to examine, besides the milk of the lactescent fungi, those species which, when cut in pieces, change their colour on the contact of atmospheric air. Though we have referred the palo de vaca to the family of the sapotas, we have nevertheless found in it a great resemblance to some plants of the urticeous kind, especially to the fig-tree, because of its terminal stipulae in the shape of a horn ; and to the brosimum, on account of the struc- ture of its fruit. M. Kunth would even have preferred this last classifi- cation ; if the description of the fruit, made on the spot, and the nature of the milk, which is acrid in the urticese, and sweet in the sapotas, did not seem to confirm our conjecture. Bredemeyer saw, like us, the fruit, and not the flower of •*•• o^w .xee. He asserts that he observed [some- times ?] two seeds, lying one against the other, as in the alligator pear- tree (Laurus persea). Perhaps this botanist had the intention of ex- pressing the same conformation of the nucleus that Swartz indicates in the description of the brosimum : — "nucleus bilobus aut bipartibilis." We have mentioned the places where this remarkable tree grows : it will bd easy for botanical travellers to procure the flower of the palo de vaca and to remove the doubts which still remain, of the family to which • belongs. 56 CULTIVATION OF COTTOK. the trinks of bamboos, supply ladders, and facilitate in a thousard ways the construction of a hut, and the fabrication of chairs, beds, and other articles of furniture that compose the wealth of a savage household. In the midst of this lavish vegetation, so varied in its productions, it requires very powerful motives to excite man to labour, to rouse him from his lethargy, and to unfold his intellectual faculties. Cacao and cotton are cultivated at Barbula. We there found, what is very rare in that country, two large cylin- drical machines for separating the cotton from its seed; one put in motion by an hydraulic wheel, and the other by & wheel turned by mules. The overseer of the farm, who had constructed these machines, was a native of Merida. He was acquainted with the road that leads from Nueva Valencia, by the way of Gruanare and Misagual, to Varinas ; and thence by the ravine of Collejones, to the Paramo de Mucuchies and the mountains of Merida covered with eternal snows. The notions he gave us of the time requisite for going from Valencia by Varinas to the Sierra Nevada, and thence by the port of Torunos, and the Bio Santo Domingo, to San Fernando de Apure, were of infinite value to us. It can scarcely be imagined in Europe, how difficult it is to obtain accurate information in a country where the commu- nications are so rare ; and where distances are diminished or exaggerated according to the desire that may be felt to encou- rage the traveller, or to deter him from his purpose. 1 had resolved to visit the eastern extremity of the Cordilleras of New Grenada, where they lose themselves in the paramos of Timotes and Niquitao. I learned at Barbula, that this excursion would retard our arrival at the Orinoco thirty-five days. This delay appeared to us so much the longer, as the rains were expected to begin sooner than usual. We had the hope of examining afterwards a great number of moun- tains covered with perpetual snow, at Quito, Peru, and Mexico ; and it appeared to me still more prudent to relin- quish our project of visiting the mountains of Merida, since by so doing we might miss the real object of our journey, that of ascertaining by astronomical observations the point of communication between the Orinoco, the Rio Negro, ind the river Amazon. We returned in consequence from Barbula to GKiacara, to take leave of the family of the CABNIVAL SPOUTS. 57 Marquis del Toro, and pass three days more on the borders of the lake. It was the carniva* season, and all was gaiety. The sports in which the people indulge, and which are called carnes tollendas* assume occasionally somewhat of a savage character. Some led an ass loaded with water, and, where- ever they found a window open, inundated the apartment within by means of a pump. Others carried bags filled with hairs of picapica ;t and blew the hair, which causes a great irritation of the skin, into the faces of those who passed by. From Gruacara we returned to Nueva Valencia. We found there a few French emigrants, the only ones we saw during five years passed in the Spanish colonies. Notwith- standing the ties of blood which unite the royal families of France and Spain, even French priests were not permitted to take refuge in that part of the New World, where man with such facility finds food and shelter. Beyond the At- lantic, the United States of America afford the only asylum to misfortune. A government, strong because it is free, con- fiding because it is just, has nothing to fear in giving refuge the proscribed. We have endeavoured above to give some notions of the tate of the cultivation of indigo, cotton, and sugar, in the >rovince of Caracas. Before we quit the valley of Aragua id its neighbouring coast, it remains for us to speak of the icao-plantations, which have at all times been considered as the principal source of the prosperity of those countries. The province of Caracas,^ at trie end of the eighteenth century, produced annually a hundred and fifty thousand 'megas, of which a hundred thousand were consumed in Spain, and thirty thousand in the province. Estimating a "mega of cacao at only twenty-five piastres for the price ;iven at Cadiz, we find that the total value of the exporta- tion of cacao, by the six ports of the Capitania General of * Or "farewell to flesh."

(58 niEPAiiATioN or CHOCOLATE. Caracas, amounts to four million eight hundred thousand piastres. So important an object of commerce merits a careful discussion ; and I flatter myself, that, from the great number of materials 1 have collected on all the branches of colonial agriculture, I shall be able to add something to the information published by M. Depons, in his valuable work on the provinces of Venezuela. The tree which produces the cacao is not at present found wild in the forests of Terra Firma to the north of the Orinoco ; we began to find it only beyond the cataracts of Ature and Maypure. It abounds particularly near the banks of the Ventuari, and on the Upper Orinoco, between the Padamo and the Grehette. This scarcity of wild cacao- trees in South America, north of the latitude of 6°, is a very curious phenomenon of botanical geography, and yet little known. This phenomenon appears the more surprising, as, according to the annual produce of the harvest, the number of trees in full bearing in the cacao-plantations of Caracas, Nueva Barcelona, Venezuela, Varinas, and Maracaybo, is estimated at more than sixteen millions. The wild cacao- tree has many branches, and is covered with a tufted and dark foliage. It bears a very small fruit, like that variety which the ancient Mexicans called tlalcacahuatl. Trans- planted into the conucos of the Indians of Cassiquiare and the Bio Negro, the wild tree preserves for several genera- tions that force of vegetable life, which makes it bear fruit in the fourth year ; while, in the province of Caracas, the harvest begins only the sixth, seventh, or eighth year. It is later in the inland parts than on the coasts and in the valley of G-uapo. \Ve met with no tribe on the Orinoco that prepared a beverage with the seeds of the cacao-tree. The savages suck the pulp of the pod, and throw away the seeds, which are often found in heaps where they have passed the night. Though chorote, which is a very weak infusion of cacao, is considered on the coast to be a very ancient beverage, no historical fact proves that chocolate, or any preparation whatever of cacao, was known to the natives of Venezuela before the arrival of the Spaniards. It appears to me more probable that the cacao-plantations of Caracas were suggested by those of Mexico and Gruatimala ; and that the Spaniards inhabiting Terra Eirma learned the EARLY USE OF C1IOCOJ.A.TE. 59 cultivation of the cacao-tree, sheltered in its youth by the foliage of the crythrina and plantain;* the fabrication of cakes of chocolatl, and the use of the liquid of the same name, in course of their communications with Mexico, Goia- timahi, and Nicaragua. Down to the sixteenth century travellers differed in opinion respecting the chocolatl. Benzoni plainly says that it is a drink "titter for hogs than men."t The Jesuit Acosta asserts, that " the Spaniards who inhabit America are fond of chocolate to excess ; but that it requires to be accustomed to that black beverage not to be disgusted at the mere sight of its froth, which swims on it like yeast on a fermented liquor." He adds, "the cacao is a prejudice (una supersticion) of the Mexicans, as the coca is a pre- judice of the Peruvians." These opinions remind us of Madame de Sevigne's prediction respecting the use of coffee. Fernando Cortez and his page, the gentilhombre del gran Conquistador, whose memoirs were published by Eamusio, on the contrary, highly praise chocolate, not only as an agreeable drink, though prepared cold,J but in particular as a nutritious substance. "He who has drunk one cup," says the page of Fernando Cortez, " can travel a whole day without any other food, especially in very hot climates ; for chocolate is by its nature cold and refreshing." We shall not subscribe to the latter part of this assertion ; but we shall spon have occasion, in our voyage on the Orinoco, and our excursions towards the summit of the Cordilleras, to celebrate the salutary properties of chocolate. It is easily conveyed and readily employed : as an aliment it contains a large quantity of nutritive and stimulating particles in a small compass. It has been said with truth, that in the East, rice, gum, and ghee (clarified butter), assist man in crossing the deserts; and so, in the New World, cho- * This process of the Mexican cultivators, practised on the coast of Caracas, is desciibed in the memoirs known under the title of " Rela- «ione di certo Gentiluomo del Signor Cortez, Conquistadore del Messico."

The cacao harvest is extremely variable. The tree vege- tates with such vigour that flowers spring out even from the roots, wherever the earth leaves them uncovered. It suffers from the north-east winds, even when they lower the tem- perature only a few degrees. The heavy showers that fall irregularly after the rainy season, during the winter months, from December to March, are also very hurtful to the cacao-tree. The proprietor of a plantation of fifty thousand trees often loses the value of more than four or five thou- sand piastres in cacao in one hour. Great humidity is favourable to the tree only when it augments progressively, and is for a long time uninterrupted. If, in the season of drought, the leaves and the young fruit be wetted by a violent shower, the fruit falls from the stem ; for it appears that the vessels which absorb water break from being ren- dered turgid. Besides, the cacao-harvest is one of the most uncertain, on account of the fatal effects of inclement sea- sons, and the great number of worms, insects, birds, and quadrupeds,* which devour the pod of the cacao-tree ; and this brancr of agriculture has the disadvantage of obliging the new planter to wait eight or ten years for the fruit of his labours, and of yielding after all an article of very difficult preservation. The finest plantations of cacao are found in the province of Caracas, along the coast, between Caravalleda and the mouth of the Bio Tocuyo, in the valleys of Caucagua, Capaya, Curiepe, and Guapo; and in those of Cupira, between cape Conare and cape TJnare, near Aroa, Bar- quesimeto, Guigue, and Uritucu. The cacao that grows on the banks of the Uritucu, at the entrance of the llanos, in the jurisdiction of San Sebastian de las Beyes, is considered to be of the finest quality. Next to the cacao of Uritucu comes that of Guigue, of Caucagua, of Capaya, and of Cupira. The merchants of Cadiz assign the first rank to the cacao of Caracas, immediately after that rf Socomusco ; and its price is generally from thirty to forty per cent, higher than that of Guayaquil. * Parrots, monkeys, agoutis, squirrels, and stags. EXPORT OF CACAO. 61 It is only since the middle of the seventeenth century, when the Dutch, tranquil possessors of the island of Curacoa, awakened, by their smuggling, the agricultural industry of the inhabitants of the neighbouring coasts, that cacao has become an object of exportation in the province of Caracas. We are ignorant of everything that passed in those countries before the establishment of the Biscay Company of Guipuzcoa, in 1728. No precise statistical data have reached us: we only know that the exportation of cacao from Caracas scarcely amounted, at the beginning of the eighteenth century, to thirty thousand fanegas a-year. From 1730 to 1748, the company sent to Spain eight hun- dred and fifty-eight thousand nine hundred and seventy- eight i'anegas, which make, on an average, forty-seven thou- sand seven hundred fanegas a-year ; the price of the fanega fell, in 1732, to forty-five piastres, when it had before kept at eighty piastres. In 1763 the cultivation had so much augmented, that the exportation rose to eighty thousand six hundred and fifty-nine fanegas. In an official document, taken from the papers of the minister of finance, the annual produce (la cosecha) of the province of Caracas is estimated at a hundred and thirty- five thousand fauegas of cacao; thirty -three thousand of which are for home consumption, ten thousand for other Spanish colonies, seventy-seven thousand for the mother- country, fifteen thousand for the illicit commerce with the French, English, Dutch, and Danish colonies. From 1789 to 1793, the importation of cacao from Caracas into Spain was, on an average, seventy-seven thousand seven hundred aud nineteen fanegas a-year, of which sixty-five thousand seven hundred and sixty-six were consumed in the country, and eleven thousand nine hundred and fifty-three exported to France, Italy, and Germany. The late wars have had much more fatal effects on the cacao trade of Caracas than on that of Guayaquil. On account of the increase of price, less cacao of the first quality has been consumed in Europe. Instead of mixing, as was done formerly for common chocolate, one quarter of the cacao of Caracas, with three-quarters of that of Guayaquil, the latter has been employed pure in Soain. We nii'st here 62 EXHAUSTION OF TITE SOIL. remark, that a groat deal of cacao of an inferior quality, such as that of Muranon, the liio Negro, Honduras, and the island of St. Lucia, bears the name, in commerce, of Guayaquil cacao. The exportation from that port amounts only to sixty thousand fanegas; consequently it is two- thirds less than that of the ports of the Capitania- General of Caracas. Though the plantations of cacao have augmented in the provinces of Cumana, Barcelona, and Maracaybo, in pro- portion as they have diminished in the province of Caracas, it is still believed that, in general, this ancient branch of agricultural industry gradually declines. In many parts coffee and cotton-trees progressively take place of the cacao, of which the lingering harvests weary the patience of the cultivator. It is also asserted, that the new plantations of cacao are less productive than the old; the trees do not acquire the same vigour, and yield later and less abundant fruit. The soil is still said to be exhausted ; but probably it is rather the atmosphere that is changed by the progress of clearing and cultivation. The air that reposes on a virgin soil covered with forests is loaded with humidity and those gaseous mixtures that serve for the nutriment of plants, and arise from the decomposition of organic substances. When a country has been long subjected to cultivation, it is not the proportions between the azote and oxygen that vary. The constituent bases of the atmosphere remain unaltered ; but it no longer contains, in a state of suspen- sion, those binary and ternary mixtures of carbon, hydrogen, and nitrogen, which a virgin soil exhales, and which are regarded as a source of fecundity. The air, purer and less charged with miasmata and heterogeneous emanations, be- comes at the same time drier. The elasticity of the vapours undergoes a sensible diminution. On land long cleared, and consequently little favourable to the cultivation of the cacao-tree (as, for instance, in the West India Islands), the fruit is almost as small as that of the wild cacao-tree. It is on the banks of the Upper Orinoco, after having crossed the Llanos, that we find the true country of the cacao-tree, thick forests, in which, on a virgin soil, and surrounded by an atmosphere continually humid, the tree? furnish, from ADULTERATION OF CACAO. the fourth year, abundant crops. "Wherever the soil is not exhausted, the fruit lias become by cultivation larger and bitter, but also later. On seeing the produce of cacao gradually dimmish in Terra Firma, it may be inquired, whether the consumption will diminish in the same proportion in Spain, Italy, and the rest of Europe ; or whether it be not probable, that by the destruction of the cacao plantations, the price will augment sufficiently to rouse anew the industry of the cultivator. This latter opinion is generally admitted by those who deplore, at Caracas, the diminution of so ancient and profitable a branch of commerce. In proportion as civilization extends towards the humid forests of the inte- rior, the banks of the Orinoco and the Amazon, or towards the valleys that furrow the eastern declivity of the Andes the new planters will find lands and an atmosphere equally favourable to the culture of the cacao-tree. The Spaniards, in general, dislike a mixture of vanilla with the cacao, as irritating the nervous system ; the fruit, therefore, of that orchideous plant is entirely neglected in the province of Caracas, though abundant crops of it might be gathered on the moist and feverish coast between Porto Cabello and Ocumare; especially at Turiamo, where the fruits of the Epidendrum vanilla attain the length af eleven or twelve inches. The English and the Anglo-Americans often seek to make purchases of vanilla at the port of La Guayra, but the merchants procure with difficulty a very small quantity. In the valleys that descend from the chain of the coast towards the Caribbean Sea, in the province of Truxillo, as well as in the Missions of Guiana, near the cataracts of the Orinoco, a great quantity ol vanilla might be collected; the produce of which would be still more abundant, if, according to the practice of the Mexicans, the plant were disengaged, from time to time, from the creeping plants by which it is entwined and stifled. The hot and fertile valleys of the Cordillera of the coast of Venezuela occupy a tract of land which, on the west, towards the lake of Maracaybo, displays a remarkable variety of scenery. I shall exhibit in one view, to close this chapter, the facts I have been able to collect -espectmg $£ CORDILLERA OF THE COAST. the quality of the soil and the metallic riches of tLe districts oF Area, of Barquesnneto, and of Carora. From tne Sierra Nevada of Merida, and the paramos of Niquitao, Bocono, and Las Rosas,* which contain the valu- able bark-tree, the eastern Cordillera of New Granada t decreases in height so rapidly, that, between the ninth and tenth degrees of latitude, it forms only a chain of little mountains, which, stretching to the north-east by the Altar and Torito, separates the rivers that join the Apure and the Orinoco from those numerous rivers that flow either into the Caribbean Sea or the lake of Maracaybo. On this dividing ridge are built the towns of Nirgua, San Felipe el Fuerte, Barquesioeto, and Tocuyo. The first three are in a very hot climate; but Tocuyo enjoys great coolness, and we heard with surprise, that, beneath so fine a sky, the inhabitants have a strong propensity to suicide. The ground rises towards the south; for Truxillo, the lake of IJrao, from which carbonate of soda is extracted, and La Grita, all to the east of the Cordillera, though no farther distant, are four or five hundred toises high. On examining the law which the primitive strata of the Cordillera of the coast follow in their dip, we believe we recognize one of the causes of the extreme humidity of the land bounded by this Cordillera and the ocean. The dip of the strata is most frequently to the north-west ; so that the waters flow in that direction on the ledges of rock; and form, as we have stated above, that multitude of torrents and rivers, the inundations of which become so fatal to the * Many travellers, who were monks, have asserted that the little Paramo de Las Rosas, the height of which appears to be more than 1,600 toises, is covered with rosemary, and the red and white roses of Europe grow wild there. These roses are gathered to decorate the altars in the neighbouring villages on the festivals of the church. By what accident has our Rosa centifolia become wild in this country, while we nowhere found it in the Andes of Quito and Peru ? Can it really be the rose-tree of our garden ? f The bark exported from the port of Maracaybo does not come from the territory of Venezuela, but from the mountains of Pamplona in New Grenada, being brought down the .'Rio de San Faustino, that flows into the lake of Maracaybo.

Among the rivers which descend north-east toward the coast of Porto Cabello, and La Punta de Hicacos, the most remarkable are those of Tocuyo, Aroa, and Yaracuy. Were it not for the miasmata which infect the atmosphere, the val- leys of Aroa and of Yaracuy would perhaps be more popu- lous than those of Aragua. Navigable rivers would even give the former the advantage of facilitating the exportation of their own crops of sugar and cacao, and that of the pro- ductions of the neighbouring lands ; as the wheat of Quibor, the cattle of Monai, and the copper of Aroa. The mines from which this copper is extracted, are in a lateral valley, opening into that of Aroa ; and which is less hot, and less unhealthy, than the ravines nearer the sea. In the latter the Indians have their gold-washings, and the sou conceals rich copper-ores, which no one has yet attempted to extract. The ancient mines of Aroa, after having been long neglected, have been wrought anew by the care of Don Antonio Hen- riquez, whom we met at San Fernando on the borders of the, Apure. The total produce of metallic copper is twelve or fit teen hundred quintals a year. This copper, known at Cadiz by the name of Caracas copper, is of excellent quality. It is even preferred to that of Sweden, and of Coquimbo in Chile. Part of the copper of Aroa is employed for making bells, which are cast on the spot. Some ores of silver have been recently discovered between Aroa and Nirgua, near Guanita, in the mountain of San Pablo. Grains of gold are found in all the mountainous lands between the Rio Yaracuy, the town of San Felipe, Nirgua, and Barque- simeto; particularly in the Rio de Santa Cruz, in which the Indian gold-gatherers have sometimes found lumps of the value of four or five piastres. Do the neighbouring rocks of mica-slate and gneiss contain veins ? or is the gold dis- seminated here, as in the granites of Guadarama in Spain, and of the Fichtelberg in Franconia, throughout the whole mass of the rock? Possibly the waters, in filtering through it, bring together the disseminated grains of gold; in which case every attempt to work the rock would be useless. In the Savana de la Miel, near the town of Barquesimeto, a ihaft has been sunk in a black shining slate resembling VOL. II. F CO MCNTCIPALITT OF KEGBOEB. ampelite. The minerals extracted from this shaft, which were sent to me at Caracas, were quartz, non-auriferous pyrites, and carbonated lead, crystallized in needles of a silky lustre. In the early times of the conquest the working of the mines of Nirgua and of Buria* was begun, notwithstanding the incursions of the warlike nation of the Griraharas. In this very district the accumulation of negro slaves in 1553 gave rise to an event bearing some analogy to the insur- rection in St. Domingo. A negro slave excited an insur- rection among the miners of the Real de San Felipe de Buria. He retired into the woods, and founded, with two hundred of his companions, a town, where he was proclaimed king. Miguel, this new king, was a friend to pomp and parade. He caused his wife &uiomar, to assume the title of queen; and, according to Ovtedo, he appointed ministers and counsellors of state, officers of the royal household, and even a negro bishop. He soon after ventured to attack the neighbouring town of Nueva Segovia de Barquesimeto ; but, being repulsed by Diego de Losada, he perished in the conflict. This African monarchy was succeeded at Nirgua by a republic of Zamboes, the descendants of negroes and Indians. The whole municipality (cabildo) is composed of men of colour to whom the king of Spain has given the title of " his faithful and loyal subjects, the Zamboes of JSTirgua." Few families of Whites will inhabit a country where the system of government is so adverse to their pretensions ; and the little town is called in derision La republica de Zambos y Mulatos. If the hot vallies of Aroa, of Taracuy, and of the Rio Tocuyo, celebrated for their excellent timber, be rendered feverish by luxuriance of vegetation, and extreme atmo- spheric humidity, it is different in the savannahs of Monai and Carora. These Llanos are separated by the moun- tainous tract of Tocuyo and Nirgua from the great plains of La Portuguesa and Calabozo. It is very extraordinary to see barren savannahs loaded with miasmata. No marshy ground is found there, but several phenomena indicate a * The valley of Buria, and the little river of the same name, com- municate with the valley of the Rio Coxede, or the Rio de Barque* INFLAMMABLE EXHALATIONS. 67 disengagement of hydrogen.* When travellers, who ore not acquainted with natural inflammable gases, are shown the Cueva del Serrito de Monai, the people of the country love to frighten them by setting fire to the gaseous combination which is constantly accumulated in the upper part of the cavern. M^y we attribute the insalubrity of the atmosphere to the same causes as those which operate in the plains be- tween Tivoli and Home, viz., disengagements of sulphuretted hydrogen ?f Possibly, also, the mountainous lands, near the llanos of Monai, may have a baneful influence on the surrounding plains. The south-easterly winds may convey to them the putrid exhalations that rise from the ravine of Villegas, and from La Sienega de Cabra, between Carora and Carache. I am desirous of collecting every circum- stance having a relation to the salubrity of the air ; for, in a matter so obscure, it is only by the comparison of a great num- ber of phenomena, that we can hope to discover the truth. The barren yet feverish savannahs, extending from Ear- quesimeto to the eastern shore of the lake of Maracaybo, are partly covered with cactus; but the good silvester-cochineal, known by the vague name of grana de Carora, comes from a more temperate region, between Carora and Truxillo, and * What is that luminous phenomenon known under the name of the Lantern (farol) of Maracaybo, which is perceived every night toward the seaside as well as in the inland parts, at Merida for example, where M. Palacios observed it during two years? The distance, greater than 40 leagues, at which the light is observed, has led to the siipposition that it might be owing to the effects of a thunderstorm, or of electrical explo- sions which might daily take place in a pass in the mountains. It is asserted that, on approaching the farol, the rolling of thunder is heard. Others vaguely allege that it is an air-volcano, and that asphaltic soils, like those of Mena, cause these inflammable exhalations which are so constant in their appearance. The phenomenon is observed on a moun- tainous and uninhabited spot, on the borders of the Rio Cutatumbo, near its junction with the Rio Sulia. The situation of the farol is such that, being nearly in the meridian of the opening (boca) of the lake of Mara- caybo, navigators are guided by it as by a lighthouse. t Don Carlos del Pozo has discovered in this district, at the bottom of the Quebrada de Moroturo, a stratum of clayey earth, black, strongly soiling the fingers, emitting a powerful smell of sulphur, and inflaming spontaneously when slightly moistened and exposed for a long time to the rays of the tropical sun.

Mountains which separate the Valleys of Aragua from the Llanos of Caracas.— Villa de Cura. — Parapara. — Llanos or Steppes. — Calabozo. THE chain of mountains, bordering the lake of Tacarigua towards the south, forms in some sort the northern shore of the great basin of the Llanos or savannahs of Caracas. To descend from the valleys of Aragua into these savannahs, it is necessary to cross the mountains of Guigue and of Tucu- tunemo. Prom a peopled country embellished by culti- vation, we plunge into a vast solitude. Accustomed to the aspect of rocks, and to the shade of valleys, the traveller beholds with astonishment these savannahs without trees, these immense plains, which seem to ascend to the horizon. Before I trace the scenery of the Llanos, or of the region of pasturage, I will briefly describe the road we took from Nueva Valencia, by Villa de Cura and San Juan, to the little village of Ortiz, at the entrance of the steppes. We left the valleys of Aragua on the 6th of March before sunrise. We passed over a plain richly cultivated, keeping along the south-west side of the lake of Valencia, and cross- ing the ground left uncovered by the waters of the lake. AVe were never weary of admiring the fertility of the soil, covered with calabashes, water-melons, and plantains. The rising of the sun was announced by the distant noise of the howling monkeys. Approaching a group of trees, which rise in the midst of the plain, between those parts which were anciently the islets of Don Pedro and La Negra, we saw numerous bands of araguatos moving as in procession and very slowly, from one tree to another. A male was followed by a great number of females; several of the latter carrying * This little river descends from the Paramo de los Conejos, and flow* csio the Rio Albarregas. EXAGGERATED TALES. 69 their young on their shoulders. The howling monkeys, which live in society in different parts of America, every- where resemble eacn other in their manners, though the species are not always the same. The uniformity with A\liichthe araguatos* perform their movements is extremely striking. Whenever the branches of neighbouring trees do not touch each other, the male who leads the party sus- pends himself by the callous and prehensile part of his tail ; and, letting fall the rest of his body, swings himself till in one of his oscillations he reaches the neighbouriug branch. The whole file performs the same movements on the same spot. It is almost superfluous to add how dubious is the assertion of Ulloa, and so many otherwise well- informed travellers, according to whom, the marimondos,f the araguatos, and other monkeys with a prehensile tail, form a sort of chain, in order to reach the opposite side of a river.J We had opportunities, during five years, of observing thousands of these animals; and for this very reason we place no confidence in statements possibly invented by the Europeans themselves, though repeated by the Indians of the Missions, as if they had been transmitted to them by their fathers. Man, the most remote from civi- lization, enjoys the astonishment he excites in recounting the marvels of his country. He says he has seen what he imagines may have been seen by others. Every savage is a hunter, and the stories of hunters borrow from the imagi- nation in proportion as the animals, of which they boast the artifices, are endowed with a high degree of intelligence. Hence arise the fictions of which foxes, monkeys, crows, and the condor of the Andes, have been the subjects in both hemispheres. The araguatos are accused of sometimes abandoning their young, that they may be lighter for flight when pursued by the Indian hunters. It is said that mothers have been seen removing their young from their shoulders, and throwing them down to the foot of the tree. I am inclined to believe that a movement merely accidental has been mistaken for • Simia ursina. t Simia belzebuth. % Ulloa has not hesitated to represent in an engraving this extraordi- nary feat of the monkeys with a prehensile tail. — See Viage 6 la America Meridional (Madrid, 1748). 70 HOWLING OF THE APES. one premeditated. The Indians have a dislike and a pre- dilection for certain races of monkeys ; they love the viu- ditas, the titis, and generally all the little sagoins ; while the araguatos, on account of their mournful aspect, and their uniform howling, are at once detested ana abused. In reflecting on the causes that may facilitate the pro- pagation of sound in the air during the night, I thought it important to determine with precision the distance at which, especially in damp and stormy weather, the howling of a band of araguatos is heard. I believe I obtained proof of its being distinguished at eight hundred toises distance. The monkeys which are furnished with four hands cannot make excursions in the Llanos; and it is easy, amidst vast plains covered with grass, to recognize a solitary group of trees, whence the noise proceeds, and which is inhabited by howling monkeys. Now, by approaching or withdrawing from this group of trees, the maximum of the distance may be measured, at which the howling is heard. These dis- tances appeared to me sometimes one-third greater during the night, especially when the weather was cloudy, very hot, and humid. The Indians pretend that when the araguatos fill the forests with their howling, there is always one that chaunts as leader of the chorus. The observation is pretty accurate. During a long interval one solitary and strong voice is gene- rally distinguished, till its place is taken by another voice of a different pitch. We may observe from time to time the same instinct of imitation among frogs, and almost all animals which live together and exert their voices in union. The Missionaries further assert, that, when a female among the araguatos is on the point of bringing forth, the choir suspends its bowlings till the moment of the birth of the young. I could not myself judge of the accuracy of this assertion ; but I do not believe it to be entirely unfounded. I have observed that, when an extraordinary incident, the moans for instance of a wounded araguato, fixed the atten- tion of the band, the bowlings were for some minutes suspended. Our guides assured us gravely, that, " to cure an asthma, it is sufficient to drink out of the bony drum of the hyoidal bone of the araguato." This animal having so eitraordinary a volume of voice, it is supposed that its TILLAGE OP OUIOUB. 71 larynx must necessarily impart to the water poured into it the virtue of curing affections of the lungs. Such is the science of the vulgar, which sometimes resembles that of the ancients. We passed the night at the village of Guigue, the latitude of which I found by observations of Canopus to be 10° 4' 11". The village, surrounded with the richest cultivation, is only a thousand toises distant from the lake of Tacarigua. \\'c lodged with an old sergeant, a native of Murcia, a man of a very original character. To prove to us that he had studied among the Jesuits, he recited the history of the creation of the world in Latin. He knew the names of Augustus, Tiberius, and Diocletian ; and while enjoying the agreeable coolness of the nights in an enclosure planted with bananas, he employed himself in reading all that related to the courts of the Koman emperors. He inquired of us with earnestness for a remedy for the gout, from which he suffered severely. " I know," said he, " a Zambo of Valencia, a famous curioso, who could cure me ; but the Zambo would expect to be treated with attentions which I cannot pay to a man of his colour, and I prefer remaining as I am." On leaving Guigue we began to ascend the chain of mountains, extending on the south of the lake towards Guacimo and La Palma. From the top of a table-land, at three hundred and twenty toises of elevation, we saw for the last time the valleys of Aragua. The gneiss appeared unco- vered, presenting the same direction of strata, and the same dip towards the north-west. Veins of quartz, that traverse the gneiss, are auriferous ; and hence the neighbouring ravine bears the name of Quebrada del Oro. We heard with surprise at every step the name of " ravine of gold," in a country where only one single mine of copper is wrought. We travelled five leagues to the village of Maria Magdalena, and two leagues more to the Villa de Cura. It was Sunday, and at the village of Maria Magdalena the inhabitants were assembled before the church. They wanted to force our muleteers to stop and hear mass. We resolved to remain ; but, after a long altercation, the muleteers pursued their way. I may observe, that this is the only dispute in whicli we became engaged from such a cause. Very erroneous ideas 72 SAN LUIS DE CUBA. are forme* m Europe of the intolerance, and even of the religious fervour of the Spanish colonists. San Luis de Cura, or, as it is commonly called, the Villa de Oura, lies in a very barren valley, running north-west and south-east, and elevated, according to my barometrical obser- vations, two hundred and sixty-six toises above the level of the ocean. The country, with the exception of some fruit- trees, is almost destitute of vegetation. The dryness of the plateau is the greater, because (and this circumstance is rather extraordinary in a country of primitive rocks) several rivers lose themselves in crevices in the ground. The Eio de Las Minas, north of the Villa de Cura, is lost in a rock, again appears, and then is ingulphed anew without reaching the lake of Valencia, towards which it flows. Cura resembles a village more than a town. We lodged with a family who had excited the resentment of government during the revolution at Caracas in 1797. One of the sons, after having languished in a dungeon, had been sent to the Havannah, to be imprisoned in a strong fortress. With what joy his mother heard that after our return from the Orinoco, we should visit the Havannah ! She entrusted me with five piastres, "the whole fruit of her savings." I earnestly wished to return them to her; but 1 feared to wound her delicacy, and give pain to a mother, who felt a pleasure in the privations she imposed on herself. All the society of the town was assembled in the evening, to admire in a magic lantern views of the great capitals of Europe. We were shown the palace of the Tuileries, and the statue of the Elector at Berlin. An apothecary who had been ruined by an unhappy pro- pensity for working mines, accompanied us in our excursion to the Serro de Chacao, very rich in auriferous pyrites. We continued to descend the southern declivity of the Cordil- lera of the coast, in which the plains of Aragua form a longitudinal valley. We passed a part of the night of the llth of March at the village of San Juan, remarkable for its thermal waters, and the singular form of two neighbour- ing mountains, called the Morros of San Juan. They form slender peaks, which rise from a wall of rocks with a very •xtensive base. The wall ia perpendicular, and resembles OFB LADY OF THE YALENCIAtfS. 73 the Devil's Wall, which surrounds a part of the group of mountains in the Hartz.* These peaks, when seen from afar in the Llanos, strike the imagination of the inhabitants of the plain, who are not accustomed to the least unequal ground, and the height of the peaks is singularly exag- gerated by them. They were described to us as being in the middle of the steppes (which they in reality bound on the north) far beyond a range of hills called La Galera. Judging from angles taken at the distance of two miles, these hiDs are scarcely more than a hundred and fifty-six toises higher than the village of San Juan, and three hundred and fifty toises above the level of the Llanos, The thermal waters glide out at the foot of these hills, which are formed of transition-limestone. The waters are impregnated with sulphuretted hydrogen, like those of Mariara, and form a little pool or lagoon, in which thy thermometer rose only to 31/3°. I found, on the night of the 9th of March, by very satisfactory observations of the stars, the latitude 01 Villa de Cura to be 10° 2' 47". The Villa de Cura is celebrated in the country for tin1 miracles of an image of the Virgin, known by the name oi Nuestra Setiora de los Valcncianos. This image was found in a ravine by an Indian, about the middle of the eighteenth century, when it became the object of a contest between the towns of Cura and San Sebastian de los Reyes. The vicars of the latter town asserting that the Virgin had made her first appearance on the territory of their parish, the Bishop of Caracas, in order to put an end to the scandal of this long dispute, caused the image to be placed in the archives of his bishopric, and kept it thirty years under seal. It was not restored to the inhabitants of Cura till 1802. After having bathed in the cool and limpid water of the little river of San Juan, the bottom of which is of basaltic griinstein, we continued our journey at two in the morning, by Ortiz and Parapara, to the Mesa de Paja. The road to the Llanos being at that time infested with robbers, several travellers joined us so as to form a sort of caravan. We proceeded down hill during six or seven hours ; and we skirted the Cerro de Florei, near which the road turns off * "Die Teufels Mauer/' near Wernigerode in Germany. ANCIENT SEA-SHORE. leading to tee great village of San Jose de Tisnao. parsed the farms of Luque and Juncalito, to enter the valleys which, on account of the bad road, and the blue colour of the slates, bear the names of Malpaso and Pie- dras Azules. This ground is the ancient shore of the great basin of the steppes, and it furnishes an interesting subject of re- search to the geologist. We there find trap-formations, pro- bably more recent than the veins of diabasis near the town of Caracas, which seem to belong to the rocks of igneous formation. They are not long and narrow streams as in Auvergne, but large sheets, streams that appear like real strata. The lithoid masses here cover, if we may use the expression, the shore of the ancient interior sea; everything subject to destruction, such as the liquid dejections, and the scoria} filled with bubbles, has been carried away. These phenomena are particularly worthy of attention on account of the close affinities observed between the phonolites and the amygdaloids, which, containing pyroxenes and horn- blende-griinsteins, form strata in a transition-slate. The better to convey an idea of the whole situation and super- position of these rocks, we will name the formations as they occur in a profile drawn from north to south. "We find at first, in the Sierra de Mariara, which belongs to the northern branch of the Cordillera of the coast, a coarse-grained granite ; then, in the valleys of Aragua, on the borders of the lake, and in the islands, it contains, as in the southern branch of the chain of the coast, gneiss and mica-slate. These last-named rocks are auriferous in the Quebrada del Oro, near Guigue; and between Villa de Cura and the Morros de San Juan, in the mountain of Chacao. The gold is contained in pyrites, which are found sometimes disseminated almost imperceptibly in the whole mass of the gneiss,* and sometimes united in small veins of quartz. Most of the torrents that traverse the moun- tains bear along with them grains of gold. The poor in- habitants of Villa de Cura and San Juan have sometimes gained thirty piastres a-day by washing the sand ; but most * The four metals, which are found disseminated in the granite rocks, as if they were of contemporaneous formation, are gold, tin, titanium, rod cobalt. DESERTED MINES. 75 commonly, in spite of their industry, they do not in a week find particles of gold of the value of two piastres. Here, however, as in every place where native gold and auriferous pyrites are disseminated in the rock, or by the destruction of the rocks, are deposited in alluvial lands, the people con- ceive the most exaggerated ideas of the metallic riches of the soil. But the success of the workings, which depends less on the abundance of the ore in a vast space of land than on its accumulation in one point, has not justified these favourable prepossessions. The mountain of Chacao, bordered by the ravine of Tucutunemo, rises seven hundred feet above the village of San Juan. It is formed of gneiss, which, especially in the superior strata, passes into mica- slate. AVe saw the remains of an ancient mine, known by the name of Real de Santa Barbara. The works were directed to a stratum of cellular quartz,* full of polyhedric cavities, mixed with iron-ore, containing auriferous pyrites and small grains of gold, sometimes, it is said, visible to the naked eye. It appears that the gneiss of the Cerro de Chacao also furnishes another metallic deposit, a mixture of copper and silver-ores. This deposit has been the object of works attempted with great ignorance by some Mexican miners under the superintendance of M. Avalo. The gal- leryf directed to the north-east, is only twenty-five toises long. We there found some fine specimens of blue carbo- nated copper mingled with sulphate of barytes and quartz ; but we could not ourselves judge whether the ore contained any argentiferous fahlerz, and whether it occurred in a stratum, or, as the apothecary who was our guide asserted, in real veins. This much is certain, that the attempt at working the mine cost more than twelve thousand piastres two years. It would no doubt have been more prudent have resumed the works on the auriferous stratum of the Real de Santa Barbara. * This stratum of quartz, and the gneiss in which it is contained, lie hor. 8 of the Freyberg compass, and dip 70° to the south-west. At a hundred toises distance from the auriferous quartz, the gneiss resumes its ordinary situation, hor. 3-4, with 60° dip to the north-west. A few strata of gneiss abound in silvery mica, and contain, instead of garnets, an immense quantity of small octahedrons of pyrites. This silvery gneisi tesembles that of the famous mine of Himmelsftlrst, in Saxony, f La Cueva de los Mexicanos. 76 STRATA Of GKETSS. The zone of gneiss just mentioned is, in the coast-chain from the sea to the Villa de Cura, ten leagues broad. In this great extent of land, gneiss and mica-slate are found exclusively, and they constitute one formation.* Beyond the town of Villa de Cura and the Cerro de Chacao the aspect of the country presents greater geognostic variety. There are still eight leagues of declivity from the table-land of Cura to the entry of the Llanos ; and on the southern slope of the mountains of the coast, four different forma- tions of rock cover the gneiss. We shall first give the description of the different strata, without grouping them systematically. On the south of the Cerro de Chacao, between the ravine of Tucutunemo and Piedras JSTegras, the gneiss is concealed beneath a formation of serpentine, of which the composition varies in the different superimposed strata. Sometimes it is very pure, very homogeneous, of a dusky olive-green, and of a conchoidal fracture : sometimes it is veined, mixed with bluish steatite, of an unequal fracture, and containing spangles of mica. In both these states I could not discover in it either garnets, hornblende, or diallage. Advancing farther to the south (and we always passed over this ground in that direction) the green of the serpentine grows deeper, and feldspar and hornblende are recognised in it: it is difficult to determine whether it passes into diabasis or alternates with it. There is, however, no doubt of its con- * This formation, which we shall call gneiss-mica-slate, is pecu- liar to the chain of the coast of Caracas. Five formations must be dis- tinguished, as MM. von Buch and Raumer have so ably demonstrated in their excellent papers on Landeck and the Riesengebirge, namely, granite, granite -gneiss, gneiss, gneiss -mica- slate, and mica-slate. Geo- logists whose researches have been confined to a small tract of land, having confounded these formations which nature has separated in several countries in the most distiact manner, have admitted that the gneiss and mica-slate alternate everywhere in superimposed beds, or furnish in- sensible transitions from one rock to the other. These transitions and alternating superpositions take place no doubt in formations of granite- gneiss and gneiss-mica-slate ; but because these phenomena are observed in one region, it does net follow that in other regions we may not find very distinct circumscribed formations of granite, gneiss, and mica-slate. The same considerations may be applied to the formations of serpentine, which are sometimes isolated, and sometimes belong to the eurite, mica- elate, and grunstelii. THE MOHltOS OF SAN JtJAK. 77 taining veins of copper-ore.* At the foot of this mountain two tine springs gush out from the serpentine. Near tiie village of San Juan, the granular diabasis appears alone uncovered, and takes a greenish black hue. The feldspar intimately mixed with the mass, may be separated into distinct crystals. The mica is very rare, and thore is no quartz,. The mass assumes at the surface a yellowish crust like dolerite and basalt. In the midst of this tract of trap-formation, the Morros of San Juan rise like two castles in ruins. They appear linked to the mornes of St Sebastian, and to La Gralera which bounds the Llanos like a rocky wall. The Morros of San Juan are formed of limestone of a crystalline texture ; sometimes very compact, sometimes spongy, of a greenish- grey, shining, composed of small grains, and mixed with scattered spangles of mica. This limestone yields a strong effervescence with acids. I could not find in it any vestige of organized bodies. It contains in subordinate strata, masses of hardened clay of a blackish blue, and carburetted. These masses are fissile, very heavy, and loaded with iron ; their streak is whitish, and they produce no efferves- cence with acids. They assume at their surface, by their decomposition in the air, a yellow colour. We seem to recognize in these argillaceous strata a tendency either to the transition-slates, or to the kieselschiefer (schistose iasper), which everywhere characterise the black transition- limestones. When in fragments, they might be taken at first sight for basalt or hornblende.f Another white lime- stone, compact, and containing some fragments of shells, backs the Morros de San Juan. I could not see the line of junction of these two limestones, or that of the calcareous formation and the diabasis. * One of these veins, on which two shafts have been sunk, wa§ directed nor. 2'i, and dipped 80° east. The strata of the serpentine, where it is stratified with some regularity, run hor. 8, and dip almost perpendicularly. I found malachite disseminated in this serpentine, where it passes into griinstein. •f I had an opportunity of examining again, with the greatest care, the rocks of San Juan, of Chacao, of Parapara, and of Calabozo, during my stay at Mexico, where, conjointly with M. del Rio, one of the most di». tinguished pupils of the school of Freyberg, I formed a geognoatical col lection for the Colegio de Miaeria of New Spain. 78 SLATE FOBMATICXS. The transverse valley which descends from Piedras Negraa and tho village of San Juan, towards Parapara and the Llanos, is filled with trap-rocks, displaying close affinity with the formation of green slates, which they cover. Some- times we seem to see serpentine, sometimes griinstein, and sometimes dolerite and basalt. The arrangement of these problematical masses is not less extraordinary. Between San Juan, Malpaso, and Piedras Azules, they form strata parallel to each other; and dipping regularly northward at an angle of 40° or 50°, they cover even the green slates in concordant stratification. Lower down, towards Para- para and Ortiz, where the amygdaloids and phonolites are connected with the griinstein, everything assumes a basaltic aspect. Balls of griinstein heaped one upon another, form those rounded cones, which are found so frequently in the Mittelgebirge in Bohemia, near Bilin, the country of pho- nolites. The following is the result of my partial obser- vations. The griinstein, which at first alternated with strata of serpentine, or was connected with that rock by insensible transitions, is seen alone, sometimes in strata considerably inclined, and sometimes in balls with concentric strata, im- bedded in strata of the same substance. It lies, near Mal- paso, on green slates, steatitic, mingled with hornblende, destitute of mica and grains of quartz, dipping, like the griinsteins, 45° toward the north, and directed, like them, 75° north-west. A great sterility prevails where these green slates predo- minate, no doubt on account of the magnesia they contain, which (as is proved by the magnesian-limestone of England*) is very hurtful to vegetation. The dip of the green slates continues the same ; but by degrees the direction of their strata becomes parallel to the general direction of the pri- mitive rocks of the chain of the coast. At Piedras Azules these slates, mingled with hornblende, cover in concordant stratification a blackish-blue slate, very fissile, and traversed by small veins of quartz. The green slates include some strata of griinstein, and even contain balls of that sub- stance. I nowhere saw the green slates a.ternate with * Magnesian limestone is of a straw-yellow colour, and contains madrepores : it lies beneath red marl, or muriatiferous red sandstone. CEREO DE FLORES. 79 the black elates of the ravine of Piedras Azules : at tts of junction these two slates appear rather to pass one into the other, the green slates becoming of a pearl-grey in pro- portion as they lose their hornblende. Farther south, towards Parapara and Ortiz, the slates dis- appear. They are concealed under a trap-formation more varied in its aspect. The soil becomes more fertile; the rocky masses alternate with strata of clay, which appear to be produced by the decomposition of the griinsteins, the amygdaloids, and the phonolites. The griinstein, wThich farther north was less granulous, and passed into serpentine, here assumes a very different character. It contains balls of mandelstein, or amygdaloid, eight or ten inches in diameter. These balls, sometimes a little flattened, are divided into concentric layers: this is the effect of decomposition. Their nucleus is almost as hard as basalt, and they are intermingled with little cavities, owing to bubbles of gas, filled with green earth, and crystals of pyroxene and mesotype. Their basis is greyish blue, rather soft, and showing small white spots which, by the regular form they present, I should conceive to be decomposed feld- spar. M. von Buch examined with a powerful lens the species we brought. He discovered that each crystal of pyroxene, enveloped in the earthy mass, is separated from it by fissures parallel to the sides of the crystal. These fissures seem to be the effect of a contraction which the mass or basis of the mandelstein has undergone. I some- times saw these balls of mandelstein arranged in strata, and separated from each other by beds of grunstein of ten or fourteen inches thick ; sometimes (and this situation is most common) the balls of mandelstein, two or three feet in Hituneter, are found in heaps, and form little mounts with rounded summits, like spheroidal basalt. The clay which separates these amygdaloid concretions arises from the de- composition of their crust. They acquire by the contact of the air a very thin coating of yellow ochre. South-west of the village of Parapara rises the little Cerro de Flores, which is discerned from afar in the steppes Almost at its foot, and in the midst of the mandelstein tract we have just been describing, a porphyritic phonolite, A mass of compact feldspar of a greenish grey, or mountain- 80 GEOLOGICAL ARRANGEMENT. green, containing long crystals of vitreous feldspar, appears exposed. It is the real porphyrschiefer of Werner ; and it would bo uimcult to distinguish, in a collection of stouee, the phonolite of Parapara from that of Biliri, in Bohemia. It does not, however, here form rocks in grotesque shapes, but little hills covered with tabular blocks, large plates extremely sonorous, translucid on the edges, and wounding the hands when broken. Such are the successions of rocks, w^hich I described on the spot as I progressively found them, from the lake of Tacarigua to the entrance of the steppes. Few places in Europe display a geological arrangement so well worthy of being studied. We saw there in succession six formations : viz., mica-slate-gneiss, green transition-slate, black transi- tion-limestone, serpentine and griinstein, amygdaloid (with pyroxene), and phonolite. I must observe, in the first place, that the substance just described under the name of griinstein, in every respect resembles that which forms layers in the mica-slate of Cabo Blanco, and veins near Caracas. It differs only by containing neither quartz, garnets, nor pyrites. The close relations we observed near the Cerro de Chacao, between the griinstein and the serpentine, cannot surprise these geologists who have studied the mountains of Eran- conia and Silesia. Near Zobtenberg* a serpentine rock al- ternates also with gabbro. In the district of Grlatz the fissures of the gabbro are filled with a steatite of a greenish white colour, and the rock which was long thought to belong to the griinsteinsf is a close mixture of feldspar and diallage. * Between Tampadel and Silsterwiz. •f In the mountains of Bareuth, in Franconia, so abundant in griinstein and serpentine, these formations are not connected together. The ser- pentine there belongs rather to the schistose hornblende (hornblend- schiefer), as in the island of Cuba. Near Guanaxuato, in Mexico, I saw it alternating with syenite. These phenomena of serpentine rocks form- ing layers in-eurite (weisstein), in schistose hornblende, in gabbro, and in syenite, are so much the more remarkable, as the great mass of gar- netiferous serpentines, which are found in the mountains of gneiss aud mica-slate, form little distinct mounts, masses not covered by other for inations. It is nut the same in the mixtures of serpentine and granulate* limestone. VARIETIES OF ROCK. 81 The grunsteins of Tucutunemo, which we consider aa constituting the same formation as the serpentine rock, contain veins of malachite and copper-pyrites. These same metalliferous combinations are found also in Franconia, in the grimsteins of the mountains of Steben and Lichtenberg. With respect to the green slates of Malpaso, which have all the characters of transition-slates, they are identical with those which M. von Buch has so well described, near Schonau, in Silesia. They contain beds of griinstein, like the slates of the mountains of Steben just mentioned.* The black limestone of the Morros de San Juan is also a transition-limestone. It forms perhaps a subordinate stratum in the slates of Malpaso. This situation would be analogous to what is observed in several parts of Switzer- land, f The slaty zone, the centre of which is the ra>dne of Piedras Azules, appears divided into two formations. On some points we think we observe one passing into the other. The griinsteins, which begin again to the south of these elates, appear to me to differ little from those found north of the ravine of Piedras Azules. I did not see there any pyroxene ; but on the very spot I recognized a number of crystals in the amygdaloid, which appears so strongly linked to the griinstein that they alternate several times. The geologist may consider his task as fulfilled when he has traced with accuracy the positions of the diverse strata ; and has pointed out the analogies traceable between these positions and what has been observed in other countries. But how can he Avoid being tempted to go back to the origin of so many different substances, and to inquire how far the dominion of fire has extended in the mountains that bound the great basin of the steppes ? In researches on the posi- tion of rocks we have generally to complain of not suffi- ciently perceiving the connection between the masses, which we believe to be superimposed on one another. Here the * On advancing into the adit for draining the Friedrich-Wilhelmstollen mine, which I caused to be begun in 1794, near Steben, and which is yet only 340 toises long, there have successively been found, in the transition- ilate subordinate strata of pure and porphyritic grtinstein, strata, of Lydian stone and ampelite (alanuschiefer), and strata of fine-grained griinstein. All these strata characterise the transition-slates. t For instance, at the Glyshorn, at the Col de Balm«, &c. fOL. il O 8:2 PHONOLITIC EOCK8. difficulty seems to arise from the too intimate and too numerous relations observed in rocks that are thought not to belong to the same family. The phonolite (or leucostine compacts of Cordier) is pretty generally regarded by all who have at once examined burn- ing and extinguished volcanos, as a flow of lithoid lava. I found no real basalt or dolerite; but the presence of pyroxene in the amygdaloid of Parapara leaves little doubt of the igneous origin of those spheroidal masses, fissured, and full of cavities. Balls of this amygdaloid are enclosed in the grunsteiu; arid this griinstein alternates on one side with a green slate, on the other with the serpentine of Tucutunemo. Here, then, is a connexion sufficiently close established between the phonolite s and the green slates, between the pyroxenic amygdaloids and the serpen- tines containing copper-ores, between volcanic substances and others that are included under the vogue name of transition-traps. All these masses are destitute of quartz like the real trap-porphyries, or volcanic trachytes. This phenomenon is the more remarkable, as the griinsteins which are called primitive almost always contain quartz in Europe. The most general dip of the slates of Piedras Azules, of the griinsteins of Parapara, and of the pyroxenic amygdaloids embedded in strata of griinstein, does not follow the slope of the ground from north to south, but is pretty regular towards the north. The strata incline towards the chain of the coast, as substances which had not been in fusion might be supposed to do. Can we admit that so many al- ternating rocks, imbedded one in the other, have a commor. origin ? The nature of the phonolites, which are lithoid lavas with a feldspar basis, and the nature of the green slates intermixed with hornblende, oppose this opinion. In this state of things we may choose between two solutions of the problem in question. In one of these solutions the phono- lite of the Cerro de Flores is to be regarded as the sole volcanic production of the tract ; and we are forced to unite the pyroxenic amygdaloids with the rest of the griinsteins, in one single formation, that which is so common in the transition-mountains of Europe, considered hitherto as not volcanic. In the other solution of the problem, the masses of phonolite, amygdaloid, and griinstein, which are found 1JTC1INATION OF STRATA. 83 in the south of the ravine of Piedras Azules, arc separated from the griinsteins and serpentine rocks that cover the declivity of the mountains north of the ravine. In the present state of knowledge I find difficulties almost equally great in adopting either of these suppositions ; but I have no doubt that, when the real grunsteins (not the hornblende- griinsteins) contained in the gneiss and mica-slates, shall have been more attentively examined in other places ; when the basalts (with pyroxene) forming strata in primitive rocks* and the diabases and amygdaloids in the transition mountains, shall have been carefully studied; when the texture of the masses shall have been subjected to a kind of mechanical analysis, and the hornblendes better distin- guished from the pyroxenes,t and the grunsteins from the dolerites ; a great number of phenomena which now appear isolated and obscure, will be ranged under general laws. The phonolite and other rocks of igneous origin at Parapara are so much the more interesting, as they indicate ancient eruptions in a granite zone ; as they belong to the shore of the basin of the steppes, as the basalts of Harutsh belong to the shore of the desert of Sahara; and lastly, as they are the only rocks of the kind we observed in the mountains of the Capitania- General of Caracas, which are also destitute of trachytes or trap-porphyry, basalts, and volcanic produc- tions. J The southern declivity of the western chain is tolerably steep ; the steppes, according to my barometrical measure- ments, being a thousand feet lower than the bottom of the basin of Aragua. From the extensive table-land of the Villa de Cura we descended towards the banks of the Rio Tucutunemo, which has hollowed for itself, in a serpentine rock, a longitudinal valley running from east to west, at nearly the same level as La Victoria. A transverse valley, lying generally north and south, led us into the Llanos, by * For instance, at Krobsdorf, in Silesia, a stratum of basalt has been recognized in the mica-Mate by two celebrated geologists, MM. von Buch and Raumer.

It grows very narrow in several parts. Basins, the bottoms of which are perfectly horizontal, communicate together by narrow passes with steep declivities. They were, no doubt, formerly small lakes, which, owing to the accumulation of the waters, or some more violent catastrophe, have broken down the dykes by which they were separated. This phenomenon is found in both continents, wherever we examine the longitudinal valleys forming the passages of the Andes, the Alps,* or the Pyrenees. It is probable, that the irruption of the waters towards the Llanos have given, by extraordinary rents, the form of ruins to the Morros of San Juan and of San Sebastian. The volcanic tract of Parapara and Ortis is now only 30 or 40 toises above the Llanos. The eruptions consequently took place at the lowest point of the granitic chain. In the Mesa de Paja, in the ninth degree of latitude, we entered the basin of the Llanos. The sun was almost at its zenith ; the earth, wherever it appeared sterile and des- titute of vegetation, was at the temperature of 48° or 50°.t Not a breath of air was felt at the height at which we were on our mules; yet, in the midst of this apparent calm, whirls of dust incessantly arose, driven on by those small currents of air which glide only over the surface of the ground, and are occasioned by the difference of temperature between the naked sand and the spots covered with grass. These sand- winds augment the suffocating heat of the air. Every grain of quartz, hotter than the surrounding air, radiates heat in every direction; and it is difficult to ob- serve the temperature of the atmosphere, owing to these particles of sand striking against the bulb of the thermo- meter. All around us the plains seemed to ascend to the sky, and the vast and profound solitude appeared like an ocean covered with sea-weed. According to the unequal mass of vapours diffused through the atmosphere, and the variable decrement in the temperature of the different strata of ail*, the horizon in some parts was clear and distinct ; in other parts it appeared undulating, sinuous, and as if striped. * For example, the road from the valley of Ursern to the Hospice of St. Gothard, and thence to Airolo. f A thermometer, placed in the sand, rose to 38*4° and 40" Reaumur. DBE1ET ASPECT >F PLAINS. 85 The earth there was confounded with the sky. Through the dry mist and strata of vapour the trunks of palm-trees were seen from afar, stripped of their foliage and their verdant summits, and looking like the masts of a ship descried upon the horizon. There is something awful, as well as sad and gloomy, in the uniform aspect of these steppes. Everything seems motionless ; scarcely does a small cloud, passing across the zenith, and denoting the approach of the rainy season, cast its shadow on the earth. I know not whether the first aspect of the Llanos excite less astonishment than that of the chain of the Andes. Mountainous countries, whatever may be the absolute elevation of the highest summits, have an anologous physiognomy; but we accustom ourselves with difficulty to the view of the Llanos of Venezuela and Casa- nare, to that of the Pampas of Buenos Ayres and of Chaco, which recal to mind incessantly, and during journeys of twenty or thirty days, the smooth surface of the ocean. I had seen the plains or llanos of La Mancha in Spain, and the heaths (ericeta) that extend from the extremity of Jut- land, through Luneburg and Westphalia, to Belgium. These last are really steppes, and, during several ages, only small portions of them have yielded to cultivation ; but the plains of the west and north of Europe present only a feeble image of the immense llanos of South America. It is in the south- east of our continent, in Hungary, between the Danube and the Theiss ; in Russia, between the Borysthenes, the Don, and the Volga, that we find those vast pastures, which seem to have been levelled by a long abode of the waters, and which meet the horizon on every side. The plains of Hun- gary, where I traversed them on the frontiers of Germany, between Presburg and (Edenburg, strike the imagination of the traveller by the constant mirage; but their greatest extent is more to the east, between Czegled, Debreczin, and Tittel. There they present the appearance of a vast ocean of verdure, having only two outlets, one near Gran and Waitzen, the other between Belgrade and Widdin. The different Quarters of the world have been supposed to be characterized oy the remark, that Europe has its heaths, Asia its steppes, Africa its deserts, and America its savan- nahs ; but by this distinction, contrasts are established that 86 HEATHS AND DESEKTS. are not founded either on the nature of things, cr the genius of languages. The existence of a heath always sup- poses an association of plants of the family of ericas; the steppes of Asia are not everywhere covered with saline plants; the savannahs of Venezuela furnish not only the gramma, but with them small herbaceous mimosas, legu- mina, and other dicotyledonous plants. The plains of Son- garia, those which extend between the Don and the Volga, and the puszta of Hungary, are real savannahs, pasturages abounding in grasses ;* while the savannahs to the east and west of the Eocky Mountains and of New Mexico produce chenopodiums containing carbonate and muriate of soda. Asia has real deserts destitute of vegetation, in Arabia, in Grobi, and in Persia. Since we have become better ac- quainted with the deserts in the interior of Africa, so long and so vaguely confounded together under the name ot desert of Sahara (Zahra) ; it has been observed, that in this continent, towards the east, savannahs and pastures are found, as in Arabia, situated in the midst of naked and barren tracts. It is these deserts, covered with gravel and destitute of plants, which are almost entirely wanting in the New World. I saw them only in that part of Peru, between Amotape and Coquimbo, on the shores of the Pacific. These are called by the Spaniards, not llanos, * These vast steppes of Hungary are elevated only thirty cr forty toises above the level of the sea, which is more than eighty leagues distant from them. (See Wahlenberg's Flora Carpathianica.) Baron Podmanitzky, an Hungarian nobleman, highly distinguished for his knowledge of the physical sciences, caused the level of these plains to be taken, to facilitate the formation of a canal then projected between the Danube and the Theiss. He found the line of division, or the con- vexity of the ground, which slopes on each side towards the beds of the two rivers, to be only thirteen toises above the height of the Danube. The widely extended pastures, which reach in every direction to the horizon, are called in the country, Puszta, and, over a distance of many leagues, are without any human habitation. Plains of this kind, inter- mingled with marshes and sandy tracts, are found on the western side of the Theiss, between Czegled, Csaba, Komloss, and Szarwass ; and on the eastern side, between Debreczin, Karczag, and Szoboszlo. The area of these plains of the interior basin of Hungary has been estimated, by a pretty accurate calculation, to be between two thousand five hundred and three thousand square leagues (twenty to a degree). Between Caegled, Szolnok, and Ketskemet, the plain resembles a sea of sand. THE PAMPAS. 87 but the desiertos of Sechura and Atacamez. This solitary tract is not broad, but it is four hundred and forty leagues long. The rock pierces everywhere though the quicksands. No drop of rain ever falls on it; and, like the desert of Sahara, north of Timbuctoo, the Peruvian desert affords, near Huaura, a rich mine of native salt. Everywhere else, in the New World, there are plains desert because not inhabited, but no real deserts.* The same phenomena are repeated in the most distant regions; and, instead of designating those vast treeless plains in accordance with the nature of the plants they produce, it seems natural to class them into deserts, steppes, or savannahs; into bare lands without any appearance of vegetation, and lands covered with gramina or small plants of the dicotyledonous tribe. The savannahs of America, especially those of the temperate zone, have in many works been designated by the French term prairies; but this appears to me little applicable to pastures which are often very dry, though covered with grass of four or five feet in height. The Llanos and the Pampas of South America are really steppes. They are covered with beautiful verdure in the rainy season, but in the cime of great drought they assume the aspect of a desert. The grass is then reduced to powder ; the earth cracks ; the alligators and the great ser- pents remain buried in the dried mud, till awakened from their long lethargy by the first showers of spring. These phenomena are observed on barren tracts of fifty or sixty leagues in length, wherever the savannahs are not traversed by rivers ; for on the borders of rivulets, and around little pools of stagnant water, the traveller finds at certain dis- tances, even during the period of the great droughts, thickets of mauritia, a palm, the leaves of which spread out like a fan, and preserve a brilliant verdure. The steppes of Asia are all beyond the tropics, and form very elevated table-lands. America also has savannahs of * We are almost tempted, however, to give the name of desert to lhat vast and sandy table-land of Brazil, the Campos dos Parecis, which gives birth to the rivers Tapajos, Paraguay, and Madeira, and which reach'* the summit of the highest mountains. Almost destitute of veg. tutior., it reminds us of Gobi, in Mongolia. 88 LBTEL ASPECT OF THE STEPPES. considerable extent on the backs of the mountains of Mexico, Peru, and Quito ; but its most extensive steppes, the Llanos of Cumana, Caracas, and Meta, are little raised above the level of the ocean, and all belong to the equinoctial zone. These circumstances give them a peculiar character. They have not, like the steppes of southern Asia, and the deserts of Persia, those lakes without issue, those small systems of rivers which lose themselves either in the sands, or by sub- terranean nitrations. The Llanos of America incline to the east and south ; and their running waters are branches of the Orinoco. The course of these rivers once led me to believe, that the plains formed table-lands, raised at least from one hundred to one hundred and fifty toises above the level of the ocean. I supposed that the deserts of interior Africa were also at a considerable height ; and that they rose one above another as in tiers, from the coast to the interior of the continent. No barometer has yet been carried into the Sahara. With respect to the Llanos of America, I found by barometric heights observed at Calabozo, at the Villa del Pao, and at the mouth of the Meta, that their height is only forty «.>i fifty toises above the level of the sea. The fall of the rivers is extremely gentle, often nearly imperceptible; and theio fore the least wind, or the swelling of the Orinoco, causes a reflux in those rivers that flow into it. The Indians believe themselves to be descending during a whole day, when navigating from the mouths of these rivera to their sources. The descending waters are separated from those that flow back by a great body of stagnant water, in which, the equilibrium being disturbed, whirlpools are formed very dangerous for boats. The chief characteristic of the savannahs or steppes of South America is the absolute want of hills and inequalities, — the perfect level of every part of the soil. Accordingly the Spanish conquerors, who first penetrated from Coro to the banks of the Apure, did not call them deserts or savannahs, or meadows, but plains (llanos). Often within a distance of thirty square leagues there is not an eminence of a foot high. This resemblance to the surface of the sea strikes the imagination nost powerfully where the plains ara BANKS OF THE LLANOS. 89 altogether destitute of palm-trees ; and where the mountains of the shore and of the Orinoco are so distant that they cannot be seen, as in the Mesa de Pavones. A person would be tempted there to take the altitude of the sun with a quad- rant, if the horizon of the land were not constantly misty on account of the variable effects of refraction. This equality of surface is still more perfect in the meridian of Calabozo, than towards the east, between Cari, La Villa del Pao, and Nueva Barcelona ; but it extends without interruption from the mouths of the Orinoco to La Villa de Araure and to Ospinos, on a parallel of a hundred and eighty leagues in length; and from San Carles to the savannahs of Caqueat, on a meridian of two hundred leagues. It particularly cha- racterises the New Continent, as it does the low steppes ol Asia, between the Borysthenes and the Volga, between the Irtish and the Obi. The deserts of central Africa, of Arabia, Syria, and Persia, Gobi, and Casna, present, on the contrary, many inequalities, ranges of hills, ravines without water, and rocks which pierce the sands. The Llanos, however, notwithstanding the apparent uni- formity of their surface, present two kinds of inequalities, which cannot escape the observation of the traveller. The first is known by the name of banks (bancos) ; they are in reality shoals in the basin of the steppes, fractured strata of sandstone, or compact limestone, standing four or five feet higher than the rest of the plain. These banks are some- times three or four leagues in length ; they are entirely smooth, with a horizontal surface; their existence is per- ceived only by examining their margins. The second species of inequality can be recognised only by geodesical or baro- metric le veilings, or by the course of rivers. It is called a mesa or table, and is composed of small flats, or rather convex eminences, that rise insensibly to the height of a lew toises. Such are, towards the east, in the province of Cumana, on the north of the Villa de la Merced and Can- delaria, the Mesas of Amana, of Guanipa, and of Jonoro, the direction of which is south-west and north-east ; and which, in spite of their inconsiderable elevation, divide the watert between the Orinoco and the northern coast of Terra Firm a. The convexity of the savannah alone occasions this partition : we there find the ' dividing of the waters ' (divortia aqua- 90 MOUNTAIN CHAINS. rum*), as in Poland, where, far from the Carrathian moun- tains, the plain itself divides the waters between the Baltic and the Black Sea. Geograj hers, who suppose the existence of a chain of mountains wl erever there is a line of divi- sion, have not failed to mart one in the maps, at the sources of the Rio Neveri, the Utiare, the Gruarapiche, and the Pao. Thus the priests of Mongol race, according to ancient and superstitious custom, erect oboes, or little mounds of stone, on every point where the rivers flow in an opposite direction. The uniform landscape of the Llanos; the extremely small number of their inhabitants ; the fatigue of travelling beneath a burning sky, and an atmosphere darkened by dust ; the view of that horizon, which seems for ever to fly before us ; those lonely trunks of palm-trees, which have all the same aspect, and which we despair of reaching, because they are confounded with other trunks that rise by degrees on the visual horizon ; all these causes combine to make the steppes appear far more extensive than they are in reality. The planters who inhabit the southern declivity of the chain of the coast see the steppes extend towards the south, as far as the eye can reach, like an ocean of verdure. They know that from the Delta of the Orinoco to the province of Varinas, and thence, by traversing the banks of the Meta, the Gruaviare, and the Caguan, they can advance three hundred and eighty leagues t into the plains, first from east to west, and then from north-east to south-east beyond the Equator, to the foot of the Andes of Pasto. They know by the accounts of travellers the Pampas of Buenos Ayres, which are also Llanos covered with fine grass, destitute of trees, and filled with oxen and horses become wild. They suppose that, according to the greater part of our maps of A merica, this continent has only one chain of moun- tains, that of the Andes, which stretches from south to north ; and they form a vague idea of the contiguity of all the plains from the Orinoco and the Apure to the llio de la Plata and the Straits of Magellan. Without stopping here to give a mineralogical description * " C. Manlium prope jugis [Tauri] ad divortia aquarum castrj j-5SHis»e." Livy, lib. 38, c. 75. f This is the diitauce from Timbuctoo to the northern coast of Africa. POINTS OF RESEMBLANCE. 91 of the transverse chains which divide America front oast to west, it will be sufficient to notice the general struct-.ro of a continent, the extremities of which, though situated in cli- mates little analogous, nevertheless present several features of resemblance. In order to have an exact idea of the plains, their configuration, and their limits, we must know the chains *»f mountains that form their boundaries. We have already described the Cordillera of the coast, of which the highest summit is the Silla de Caraccas, and which is linked by the Paramo de las Rosas to the Nevada de Merida, and the Andes of New Grenada. We have seen that, in the tenth degree of north latitude, it stretches from Quibor and Bar- quesimeto as far as the point of Paria. A second chain of mountains, or rather a less elevated but much larger group, extends between the parallels of 3° and 7° from the mouths of the Guaviare and the Meta to the sources of the Orinoco, the Marony, and the Essequibo, towards French and Dutch Guiana. I call this chain the Cordillera of Parime, or of the great cataracts of the Orinoco. It may be followed for a length of two hundred and fifty leagues ; but it is less a chain, than a collection of granitic mountains, separated by small plains, without being everywhere disposed in lines. The group of the mountains of Parime narrows considerably between the sources of the Orinoco and the mountains of Demerara, in the Sierras of Quimiropaca and Pacaraimo, which divide the waters between the Carony and the Rio ""arime, or Eio de Aguas Blancas. This is the scene of the tpeditions which were undertaken in search of El Dorado, id the great city of Manoa, the Timbuctoo of the New Con- aent. The Cordillera of Parime does not join the Andes of Tew Grenada, but is separated from them by a space eighty agues broad. If we suppose it to have been destroyed in lis space by some great revolution of the globe (which is scarcely probable) we must admit that it anciently branched off from the Andes between Santa Fe de Bogota and Pam- plona. This remark serves to fix more easily in the memory of the reader the geographical position of a Cordillera till now very imperfectly known. A third chain of mountains unites in 16° and 18° south latitude (by Santa Cruz de Sierra, the Serranias of Aguapehy, and the famoui 92 THREE DESCRIPTIONS Of PLAINS. Campos dos Parcels) the Andes of Peru, to the mountains of Brazil. It is the Cordillera of Chiquitos which widens in the Capitaiiia de Minas Geraes, and divides the rivers flowing into the Amazon from those of the Bio de la Plata,* not only in the interior of the country, in the meridian of ATilla Boa, but also at a few leagues from the coast, between Rio Janeiro and Bahia.t These three transverse chains, or rather these three groups of mountains stretching from west to east, within the limits of the torrid zone, are separated by tracts entirely level, the plains of Caracas, or of the Lower Orinoco ; the plains of 1iie Amazon and the Rio Negro ; and the plains of Buenos Ayres, or of La Plata. I use the term plains, because the Lower Orinoco and the Amazon, far from flowing in a valley, form but a little furrow in the midst of a vast level. The two basins, placed at the extremi- ties of South America, are savannahs or steppes, pasturage without trees; the intermediate basin, which receives the equatorial rains during the whole year, is almost entirely one vast forest, through which no other roads are known save the rivers. The strong vegetation which conceals the soil, renders also the uniformity of its level less perceptible ; and the plains of Caracas and La Plata bear no other name. The three basins we have just described are called, in the language of the colonists, the Llanos of Varinas and of Caracas, the bosques or selvas (forests) of the Amazon, and the Pampas of Buenos Ayres. The trees not only for the most part cover the plains of the Amazon, from the Cor- dillera de Chiquitos, as far as that of Parime; they also crown these two chains of mountains, which rarely attain the height of the Pyrenees. % On this account, the vast plains of the Amazon, the Madeira, and the Bio Negro, are not so distinctly bounded as the Llanos of Caracas, and the * There is only a portage or carrying-place of 5,322 bracas between the Guapore (a branch of the Marmore and of the Madeira), and the Rio Aguapehy (a branch of the Jaura and of the Paraguay). t The Cordillera of Chiquitos and of Brazil stretches toward the south- east, in the government of the Rio Grande, beyond the latitude of 30* south. J We must except the most western part of the Cordillera of Chiquitos, between Cochabamba and Santa Cruz de la Sierra where the summit! GEOLOGICAL PHENOMENA, 93 Pampas of Buenos Ayres. As the region of forests com- prises at once the plains and the mountains, it extends from 18° south to 7° and 8° north,* and occupies au extent of near a hundred and twenty thousand square leagues. This forest of South America, for in fact there is only one, is six times larger than France. It is known to Europeans only on the shores of a few rivers, by which it is traversed ; and has its openings, the extent of which is in proportion to that of the forests. We shall soon skirt the marshy savannahs, between the Upper Orinoco, the Conorichite, and the Cassi- quiare, in the latitude of 3° and 4°. There are other open- ings, or as they are called, * clear savannahs,'f in the same parallel, between the sources of the Mao and the Rio de Aguas Blancas, south of the Sierra de Pacaraima. These last savannahs, which are inhabited by Caribs, and nomad Macusis, lie near the frontiers of Dutch and French Guiana. Having noticed the geological constitution of South Ame- rica, we shall now mark its principal features. The western coasts are bordered by an enormous wall of mountains, rich in precious metals wherever volcanic fire has not pierced through the eternal snow. This is the Cordillera of the Andes. Summits of trap-porphyry rise beyond three thou- sand three hundred toises, and the mean height of the chain J is one thousand eight hundred and fifty toises. It stretches in the direction of a meridian, and sends into each hemisphere a lateral branch, in the latitudes of 10° north, and 16° and 18° south. The first of these two branches, that of the coast of Caracas, is of considerable length, and forms in fact a chain. The second branch, the Cordillera of are covered with snow ; but this colossal group almost belongs to the Andes de la Paz, of which it forms a promontory or spur, directed toward the east. * To the west, in consequence of the Llanos of Manso, and the Pampas de Huanacos, the forests do not extend generally beyond the parallels of 18° or 19° south latitude; but to the east, in Brazil (in the capitanias of San Pablo and Rio Grande), as well as in Paraguay, on the borders of the Parana, they advance as far as 25° south. f Savannas limpias, that is to say, clear of trees. t la New Grenada, Quito, and Peru, according to taken by Bouguer, La Condamine, au.d myself. 94 SMALL ELEYATION OI THE LLAFOS. Chiquitos and of the sources of the G-uapoie, is very rich in gold, and widens toward the east, in Brazil, into vast table- lands, having a mild and temperate climate. Between these two transverse chains, contiguous to the Andes, an isolated group of granitic mountains is situated, from 3° to 7° north latitude; which also runs parallel to the Equator, but, not passing the meridian of 71°, terminates abruptly towards the west, and is not united to the Andes of New Grenada. These three transverse chains have no active volcanos ; we know not whether the most southern, like the two others, be destitute of trachytes or trap-porphyry. None of their summits enter the limit of perpetual snow; and the mean height of the Cordillera of La Parime, and of the littoral chain of Caracas, does not reach six hundred toises, though some of its summits rise fourteen hundred toises above the level of the sea.* The three transverse chains are separated by plains entirely closed towards the west, and open towards the east and south-east. When we reflect on their small elevation above the surface of the ocean, we are tempted to consider them as gulfs stretching in the direction of the cur- rent of rotation. If, from the effect of some peculiar attrac- tion, the waters of the Atlantic were to rise fifty toises at the mouth of the Orinoco, and two hundred toises at the mouth of the Amazon, the flood would submerge more than the half of South America. The eastern declivity, or the foot of the Andes, now six hundred leagues distant from the coast of Brazil, would become a shore beaten by the waves. This consideration is the result of a barometric measurement, taken in the province of Jaen de Bracamoros, where the river Amazon issues from the Cordilleras. I found the mean height of this immense river only one hundred and ninety- four toises above the present level of the Atlantic. The intermediate plains, however, covered with forests, are still five times higher than the Pampas of Buenos Ayres, anc the grass-covered Llanos of Caracas and the Meta. Those Llanos which form the basin of the Orinoco, and which we crossed twice in one year, in the months of March * We do not reckon here, as belonging to the chain of the coast, th* Nevados and Paramos of Merida and of Truxillo, which are a prolonga lion of the Andes of New Grenada. CONNEXION OF THE PLAINS. 95 and July, communicate with the basin of the Amazon and the Rio Negro, bounded on one side by the Cordillera of Chiquitos, and on the other by the mountains of Parime. The opening which is left between the latter and the Andes of New Grenada, occasions this communication. The aspect of the country here reminds us, but on a much larger scale, of the plains of Lombardv. which also are only fifty or sixty toises above the level o, 53? ocean ; and are directed first from La Brenta to Turin, east and west ; and then from Turin to Coni, north and south. If we were authorized, from other geological facts, to regard the three great plains of the Lower Orinoco, the Amazon, and the Rio de la Plata as basins of ancient lakes,* we should imagine we perceived in the plains of the Rio Vichada and the Meta, a channel by which the waters of the upper lake (those of the plains of the Amazon) forced their way towards the lower basin, (that of the Llanos of Caracas,) separating the Cordillera of La Parime from that of the Andes. This channel is a kind of land-strait. The ground, which is perfectly level between the Guaviare, the Meta, and the Apure, displays no vestige of a violent irruption of the waters ; but on the edge of the Cordillera of JParime, between the latitudes of 4° and 7°, the Orinoco, flowing in a westerly direction from its source to the mouth of the Guaviare,* has forced its way through the rocks, directing its course from south to north. All the great cataracts, as we shall soon see, are within the latitudes just named. When the river has reached the mouth of the Apure in tha*; very low ground where the slope towards the north is met by the counter-slope towards the south-east, that is to say, by the inclination of the plains which rise imperceptibly towards the mountains 'of Caracas, the river turns anew and flows eastward. It appeared to me, that it was proper to fix the attention of the reader on these singular inflexions of the Orinoco because, belonging at once to two basins, its course marks, in some sort, even on the most imperfect maps, the direction of that part of the plains intervening * In Siberia, the great steppes between the Irtish and the Obi, espe- cially that of Baraba, full of salt lakes (Tchabakly, Tchany, KarasouK, •nd Topolony), appear to have been, according to the Chinese traditioi * even within historical times, an inland sea. 96 ANCIENT NATITE REMAINS. between New Grenada and tr-e western border of the mountains of La Parime. The Llanos or steppes of the Lower Orinoco and of the Meta, like the deserts of Africa, bear different names in different parts. From the mouths of the Dragon the Llanos of Cumana, of Barcelona, and of Caracas or Venezuela,* follow, running from east to west. Where the steppes turn towards the south and south-south-west, from the latitude of 8°, between the meridians of 70° and 73°, we find from north to south, the Llanos of Varinas, Cawanare, the Meta, Gruaviare, Caguau, and Caqueta.f The plains of Varinas contain some few monuments of the industry of a nation that has diappeared. Between Mijagual and the Cano de la Hacha, we find some real tumuli, called in the country the Serillos de los Indios. They are hillocks in the shape of cones, artificially formed of earth, and probably contain bones, like the tumuli in the steppes of Asia. A fine road is also discovered near Hato de la Calzada, between Varinas and Canagua, five leagues long, made before the conquest, in the most remote times, by the natives. It is a causeway of earth fifteen feet high, crossing a plain often overflowed. Did nations farther advanced in civilization descend from the mountains of Truxillo and Merido to the plains of the Bio Apure ? The Indians whom we now find between this river and the Meta, are in too rude a state to think of making roads or raising tumuli. I calculated the area of these Llanos from the Caqueta to the Apure, and from the Apure to the Delta of the Orinoco, and found to be it seventeen thousand square * The following are subdivisions of these three great Llanos, as I marked them down on the spot. The Llanos of Cumana and New Anda- lusia include those of Maturin and Terecen, of Amana, Guanipa, Jonoro, and Cari. The Llanos of Nueva Barcelona comprise those of Aragua, Pariaguan, and Villa del Pao. We distinguish in the Llanos of Caracas those of Chaguaramas, Uritucu, Calabozo or Guarico, La Portuguesa, San Carlos, and Araure. •f- The inhabitants of these plains distinguish as subdivisions, from the Rio Portuguesa to Caqueta, the Llanos of Guanare, Bocono, Nutrius or the Apure, Palmerito near Quintero, Guardalito and Arauca, the Meta, Apiay near the port of Pachaquiaro, Vichada, Guaviare, Arriari, Inirida, the Rio Hacha, and Caguan. The limits between the savannahs and the forests, in the plains that extend from the sources of the Rio Negro U Putumayo, are not sufficiently known. IMMENSE EXTENT OF THE PAMPAS. 97 leagues twenty to a degree. The part running from north to south is almost double that which stretches from east to west, between the Lower Orinoco and the littoral chain of I aracas. The Pampas on the north and north-west of Buenos Ayres, between this city and Cordova, Jujuy, and the Tucuman, are of nearly the same extent as the Llanos ; but the Pampas stretch still farther on to the length of 18° southward ; and the land they occupy is so vast, that they produce palm-trees at one 01 their extremities, while the other, equally low and level, is covered with eternal frost. The Llanos of America, where they extend in the direc- tion of a parallel of the equator, are three-fourths narrower th/in the great desert of Africa. This circumstance is very important in a region where the winds constantly blow from east to west. The farther the plains stretch in this direc- tion, the more ardent is their climate. The great ocean of sand in Africa communicates by Yemen* with Gedrosia and Beloochistan, as far as the right bank of the Indus. It is from the effect of winds that have passed over the deserts situated to the east, that the little basin of the Bed Sea, surrounded by plains which send forth from all sides radiant caloric, is one of the hottest regions of the globe. The unfortunate captain Tuckey relates,f that the centi- grade thermometer keeps there generally in the night at 34°, and by day from 40° to 44°. We shall soon see that, even in the westernmost part of the steppes of Caracas, we seldom found the temperature of the air, in the shade, above 37°. * We cannot be surprised that the Arabic should be richer than any other language of the East in words expressing the ideas of desert, unin- habited plains, and plains covered with gramina. I could give a list of thirty-five of these words, which the Arabian authors employ without always distinguishing them by the shades of meaning which each separate word expresses. Makadh and kaah indicate, in preference, plains ; bakadh, a table-land; tafr, mikfar, smlis, mahk, and habaucer, a naked desert, covered with sand and gravel ; tantifah, a steppe. Zahra means at once a naked desert and a savannah. The word steppe, or step, is Russian, and not Tartarian. In the Turco-Tartar dialect a heath is called tola or tschol. The word ffobi, which Europeans have cor- rupted into cobi, signifies in the Mongol tongue a naked desert. It ii equivalent to the scha-mo or khan-hai of the Chinese.

These physical considerations on the steppes of tie New World are linked with others more interesting, inasmuch aa t'hey are connected with the history of our speeies. The great sea of sand in Africa, the deserts without water, are frequented only by caravans, that take fifty days to traverse them.* Separating the Negro race from the Moors, and the Berber and Kabyle tribes, the Sahara is inhabited only in the oases. It affords pasturage only in the eastern part, where, from the effect of the trade-winds, the layer of sand being less thick, the springs appear at the surface of the earth. In America, the steppes, less vast, less scorching, fertilized by fine rivers, present fewer obstacles to the inter- course of nations. The Llanos separate the chain of the coast of Caracas and the Andes of New Grenada from the region of forests ; from that woody region of the Orinoco which, from the first discovery of America, has been inha- bited by nations more rude, and farther removed from civilization, than the inhabitants of the coast, and still more than the mountaineers of the Cordilleras. The steppes, however, were no more heretofore the rampart of civiliza- tion than they are now the rampart of the liberty of the hordes that live in the forests. They have not hindered the nations of the Lower Orinoco from going up the little rivers and making incursions to the north and the west. If, according to the various distribution of animals on the globe, the pastoral life could have existed in the New World, — if, before the arrival of the Spaniards, the Llanos and the Pampas had been filled with those numerous herds of cows and horses that graze there, Columbus would have found the human race in a state quite different. Pastoral nations living on milk and cheese, real nomad races, would have spread themselves over those vast plains which com- municate with each other. They would have been seen at the period of great droughts, and even at that of inunda- tions, fighting for the possession of pastures ; subjugating one another mutually ; and, united by the common tie of manners, language, and worship, they would have risen to that state of demi-civilization which we observe with surprise in the nations of the Mongol ana Tartar race. * This is the maximum of the time, according to Major ReunelL /Traveia of Mungo Park, voL ii. ) JOURNEY ACROSS THE LLANOS. 99 America would then, like the centre of Asia, haTe had its conquerors, who, ascending from the plains to the table- lands of the Cordilleras, and abandoning a wandering life, would have subdued the civilized nations of Peru and New Grenada, overturned the throne of the Incas and of the Zaque,* and substituted for the despotism which is the fruit of theocracy, that despotism which arises from the patriarchal government of a pastoral people. In the New World the human race has not experienced these great moral and political changes, because the steppes, though more fertile than those of Asia, have remained without herds ; because none of the animals that furnish milk in abundance are natives of the plains of South America ; and because, in the progressive unfolding of American civiliza- tion, the intermediate link is wanting that connects the hunting with the agricultural nations. We have thought proper to bring together these general notions on the plains of the New Continent, and the con- trast they exhibit to the deserts of Africa and the fertile steppes of Asia, in order to give some interest to the nar- rative of a journey across lands of so monotonous an aspect. Having now accomplished this task, I shall trace the route by which we proceeded from the volcanic mountains of Para- para and the northern side of the Llanos, to the banks of the Apure, in the province of Varinas. After having passed two nights on horseback, and sought m vain, by day, for some shelter from the heat of the sun beneath the tufts of the moriche palm-trees, we arrived before night at the little Hato del Cayman,f called also La Guadaloupe. It was a solitary house in the steppes, sur- rounded by a few small huts, covered with reeds and skins. The cattle, oxen, horses, and mules are not penned, but wander freely over an extent of several square leagues There is nowhere any enclosure ; men, naked to the waist and armed with a lance, ride over the savannahs to inspect the animals ; bringing back those that wander too far from the pastures of the farm, and branding all that do not already bear the mark of their proprietor. These mulattos, who are known * The Zaque was the secular chief of Cundinamarca. His power was lhared with the high priest (lama) of Iraca. f The Farm of the Alligator. H 2 100 HALT AT THE HATO. by the name of peones llaneros, are partly freed- men and partly slaves. They are constantly exposed to the burn- ing heat of the tropical sun. Their food is meat, dried in the air, and a little salted; and of this even their horses sometimes partake. Being always in the saddle, they fancy they cannot make the slightest excursion on foot. We found an old negro slave, who managed the farm in the absence of his master. He told us of herds composed of several thousand cows, that were grazing in the steppes; yet we asked in vain for a bowl of milk. "We were offered, in a calabash, some yellow, muddy, and fetid water, drawn from a neighbouring pool. The indolence of the inhabitants of the Llanos is such that they do not dig wells, though they know that almost everywhere, at ten feet deep, fine springs are found in a stratum of conglomerate, or red sandstone. After suffering during one half of the year from the effect of inundations, they quietly resign themselves, during the other half, to the most distressing deprivation of water. The old negro advised us to cover the cup with a linen cloth, and drink as through a filter, that we might not be incommoded by the smell, and might swallow less of the yellowish mud suspended in the water. We did not then think that we should afterwards be forced, during whole months, to have recourse to this expedient. The waters of the Orinoco are always loaded with earthy particles ; they are even putrid, where dead bodies of alligators are found in the creeks, lying on banks of sand, or half-buried in the mud. No sooner were our instruments unloaded and safely placed, than our mules were set at liberty to go, as they say here, para luscar agua, that is, "to search for water."- There are little pools round the farm, which the animals find, guided by their instinct, by the view of some scattered tufts of mauritia, and by the sensation of humid coolness, caused by little currents of air amid an atmosphere which to us appears calm and tranquil. When the pools of water are far distant, arid the people of the farm are too lazy to load the cattle to these natural watering-places, they confine them during five or six hours in a very hot stable before they let them loose. Excess of thirst then augments their sagacity, sharpening as it were their senses and theii SEARCH FOE WATER. 101 Instinct. No sooner is the stable opened, than the horses and mules, especially the latter (for the penetration of these animals exceeds the intelligence of the horses), rush info the savannahs. With upraised tails and heads thrown bad: they run against the wind, stopping from time to time as if exploring space ; they follow less the impressions of sight than of smell ; and at length announce, by prolonged neigh- ings, that there is water in the direction of their course. All these movements are executed more promptly, and with readier success, by horses born in the Llanos, and which have long enjoyed their liberty, than by those that come from the coast, and descend from domestic horses. In animals, for the most part, as in man, the quickness of the senses is diminished by long subjection, and by the habits that arise from a fixed abode and the progress of culti- vation. We followed our mules in search of one of those pools, whence the muddy water had been drawn, that so ill quenched our thirst. We were covered with dust, ana tanned by the sandy wind, which burns the skin even more than the rays of the sun. We longed impatiently to take a bath, but we found only a great pool of feculent water, surrounded with palm-trees. The water was turbid, though, to our great astonishment, a little cooler than the air. Accustomed during our long journey to bathe whenever we 6ad an opportunity, often several times in one day, we hastened to plunge into the pool. We had scarcely begun to enjoy the coolness of the bath, when a noise which we heard on the opposite bank, made us leave the water preci- pitately. It was an alligator plunging into the mud. We were only at the distance of a quarter of a league from the farm, yet we continued walking more than an hour without reaching it. We perceived too late that we had taken a wrong direction. Having left it at the decline of day, before the stars were visible, we had gone forward into ^ie plain at hazard. We were, as usual, provided with i compass, and it might have been easy for us to steer our course from the position of Canopus and the Southern Cross; but unfortunately we were uncertain whether, on \eaving the farm, we had gone towards the east or the south. We attempted to return to the spot where we had bathed, 102 DANGEBOUS SITUATION. and we again walked three quarters of an hour without finding the pool. We sometimes thought we saw fire on the horizon; but it was the light of the rising stars enlarged by the vapours. After having wandered a long time in the savannah, we resolved to seat ourselves beneath the trunk of a palm-tree, in a spot perfectly dry, surrounded by short grass ; for the fear of water-snakes is always greater than that of jaguars among Europeans recently disembarked. We could not natter ourselves that our guides, of whom we knew the insuperable indolence, would come in search of us in the savannah before they had prepared their food and finished their repast. Whust somewhat perplexed by the uncertainty of our situation, we were agreeably affected by hearing from afar the sound of a horse advancing towards us. The rider was an Indian, armed with a lance, who had just made the rodeo, or round, in order to collect the cattle within a determinate space of ground. The sight of two white men, who said they had lost their way, led him at first to suspect some trick. We found it difficult to inspire him with confidence ; he at last consented to guide us to the farm of the Cayman, but without slackening the gentle trot of his horse. Our guides assured us that " they had already begun to be uneasy about us;" and, to justify this inquietude, they gave a long enumeration of persons who, having lost themselves in the Llanos, had been found nearly exhausted. It may be supposed that the danger is immi- nent only to those who lose themselves far from any habi- tation, or who, having been stripped by robbers, as has happened of late years, have been fastened by the body and hands to the trunk of a palm-tree. In order to escape as much as possible from the heat of the day, we set off at two in the morning, with the hope of reaching Calabozo before noon, a small but busy trading- town, situated in the midst of the Llanos. The aspect of the country was still the same. There was no moonlight ; but the great masses of nebulae that spot the southern sky en- lighten, as they set, a part of the terrestrial horizon. The solemn spectacle of the starry vault, seen in its immense •expanse; — the cool breeze which blows over the plain during the night : — the waving motion of the grass, wherever it has attained any height ; everything recalled to our minds the EFFECTS OP THE MIEAOE. 103 iurface of the ocean. The illusion was augmented when the disk of the sun appearing on the horizon, repeated its image by the effects of refraction, and, soon losing its flattened form, ascended rapidly and straight towards the zenith. Sunrise in the plains is the coolest moment of the day ; but this change of temperature does not make a very lively impression on the organs. We did not find the thermo- meter in general sink below 27*5 ; while near Acapulco, at Mexico, and in places equally low, the temperature at noon is often 32°, and at sunrise only 17° or 18°. The level surface of the ground in the Llanos, which, during the day, is never in the shade, absorbs so much heat that, notwithstanding the nocturnal radiation toward a sky without clouds, the earth and air have not time to cool very sensibly from mid- night to sunrise. In proportion as the sun rose towards the zenith, and the earth and the strata of superincumbent air took different temperatures, the phenomenon of the mirage displayed itself in its numerous modifications. This phenomenon is so common in every zone, that I mention it only because we stopped to measure with some precision the breadth of the aerial distance between the horizon and the suspended object. There was a constant suspension, with- out inversion. The little currents of air that swept the surface of the soil had so variable a temperature that, in a drove of wild oxen, one part appeared with the legs raised above the surface of the ground, while the other rested on it. The aerial distance was, according to the distance of the animal, from 3' to 4'. Where tufts of the moriche palm were found growing in long ranges, the extremities of these green rows were suspended like the capes which were, for so long a time, the subject of my observations at Cumana. A well-informed person assured us, that he had seen, be- tween Calabozo and Uritucu, the image of an animal in- verted, without there being any direct image. Niebuhr made a similar observation in Arabia. We several times thought we saw on the horizon the figures of tumuli and towers, which disappeared at intervals, without our being ible to discern the real shape of the objects. They were j-erhaps hillocks, or small eminences, situated beyond the 1O4 HEEDS OF WILD A1TLMAL8 ordinary visual horizon. I need not mention those tracts destitute of vegetation, which appear like large lakes with an undulating surface. This phenomenon, observed in very remote times, has occasioned the mirage to receive in Sanscrit the expressive name of desire of the antelope. We admire the frequent allusions in the Indian, Persian, and Arabic poets, to the magical effects of terrestrial refraction. It was scarcely known to the Greeks and Romans. Proud of the riches of their soil, and the mild temperature of the air, they would have felt no envy of this poetry of the desert. It had its birth in Asia; and the oriental poets found its source in the nature of the country they in- habited. They were inspired with the aspect of those vast solitudes, interposed like arms of the sea or gulfs, between lands which nature had adorned with her most luxuriant fertility. The plain assumes at sunrise a more animated aspect. The cattle, which had reposed during the night along the pools, or beneath clumps of mauritias and rhopalas, were now collected in herds; and these solitudes became peopled with horses, mules, and oxen, that live here free, rather than wild, without settled habitations, and disdaining the care and protection of man. In these hot climates, the oxen, though of Spanish breed, like those of the cold table-lands of Quito, are of a gentle disposition. A traveller runs no risk of being attacked or pursued, as we often were in our excursions on the back of the Cordilleras, where the climate is rude, the aspect of the country more wild, and food less abundant. As we approached Calabozo, we saw herds of roebucks browsing peacefully in the midst of horses and oxen. They are called matacani; their flesh is good ; they are a little larger than our roes, and resemble deer with a very sleek skin, of a fawn-colour, spotted with white. Their horns appear to me to have single points. They had little fear of the presence of man : and in herds of thirty or forty we observed several that were entirely white. This variety, common enough among the large stags of the cold climates of the Andes, swprised us in these low and burning plains. I have since learned, that even the jaguar, in the hot regions of Paraguay, sometimes affords albino varieties, the skin of which is of such uniform white- VEGETATION OF THE PLAIKS. 105 ness that the spots or rings can be distinguished only in the sunshine. The number of matacani, or little deer,* is so considerable in the Llanos, that a trade might be carried on with their skins.f A skilful hunter could easily kill more than twenty in a day; but such is the indolence of the inhabitants, that often they will not give themselves the trouble of taking the skin. The same indifference is evinced in the chase of the jaguar, a skin of which fetches only one piastre in the steppes of Varinas, while at Cadiz it costs four or five. The steppes that we traversed are principally covered with grasses of the genera Killingia, Cenchrus, and Pas- palum.| At this season, near Calabozo and San Jerome del Pirital, these grasses scarcely attain the height of nine or ten inches. Near the banks of the Apure and the Por- tuguesa they rise to four feet in height, so that the jaguar can conceal himself among them, to spring upon the mulea and horses that cross the plain. Mingled with these gra- mina some plants of the dicotyledonous class are found ; as turneras, malvacese, and, what is very remarkable, little mimosas with irritable leaves, || called by the Spaniards dormideras. The same breed of cows, which fatten in Europe on sainfoin and clover, find excellent nourishment in the herbaceous sensitive plants. The pastures where these shrubs particularly abound are sold at a higher price than others. To the east, in the llanos of Cari and Bar- celona, the cypura and the craniolaria,§ the beautiful white flower of which is from six to eight inches long, rise soli- tarily amid the gramina. The pastures are richest not only around the rivers subject to inundations, but also wherever the trunks of palm-trees are near each other. The least fertile spots are those destitute of trees ; and attempts to cultivate them would be nearly fruitless.

I have seen, it is true, trees of this family, in the forests of the Orinoco, spreading a tufted foliage ; but we cannot say much for the shade of the palm-tree of the llanos, the palma de cobija* which has but a few folded and palmate leaves, like those of the chamaerops, and of which the lower- most are constantly withered. We were surprised to see that almost all these trunks of the corypha were nearly of the same size, viz., from twenty to twenty-four feet high, and from eight to ten inches diameter at the foot. Nature has produced few species of palm-trees in such prodigious numbers. Amidst thousands of trunks loaded with olive- shaped fruits we found about one hundred without fruit. May we suppose that there are some trees with flowers purely monoecious, mingled with others furnished with her- maphrodite flowers ? The Llaneros, or inhabitants of the plains, believe that all these trees, though so low, are many centuries old. Their growth is almost imperceptible, being scarcely to be noticed in the lapse of twenty or thirty years. The wood of the palma de cobija is excellent for building. It is so hard, that it is difficult to drive a nail into it. The leaves, folded like a fan, are employed to cover the roofs of the huts scattered through the Llanos; and these roofs last more than twenty years. The leaves are fixed by bending the extremity of the footstalks, which have been beaten before- hand between two stones, so that they may bend without breaking. Beside the solitary trunks of this palm-tree, we find dis- persed here and there in the steppes a few clumps, real groves (palmares), in which the corypha is intermingled with a tree of the proteaceous family, called chaparro by the natives. It is a new species of rhopala,t with hard and resonant leaves. The little groves of rhopala are called chaparales; and it may be supposed that, in a vast plain, where only two or three species of trees are to be found, * The roofing palm-tree (Corypha tectorum). f Resembling the Embothrium, of which we found no species in Soutk America. The embothriums are represented in American vegetation by the genera Lomatia and Oreocallis. UTILITY OF THE PALM-TREK. 107 the chaparro, which affords shade, is considered a highly valuable plant. The coiypha spreads through the Llanos of Caracas from Mesa de Peja as far as Guayavol; farther north and north-west, near Guanare and San Carlos, its place is taken by another species of the same genus, with leaves alike palmate but larger. It is called the 'royal palm of the plains' (palma real de los Llanos).* Other palm-trees rise south of Guayaval, especially the piritu with pinnate leaves,t and the moriche (Mauritia flexuosa), cele- brated by Father Gumilla under the name of arbol de la vida, or tree of life. It is the sago-tree of America, furnishing flour, wine, thread for weaving hammocks, baskets, nets, and clothing. Its fruit, of the form of the cones of the pine, and covered with scales, perfectly resembles that of the Calamus rotang. It has somewhat the taste of the apple. When arrived at its maturity it is yellow within and red without. The araguato monkeys eat it with avidity; and the nation of the Guaraounos, whose whole existence, it may be said, is closely linked with that of the moriche palm- tree, produce from it a fermented liquor, slightly acid, and extremely refreshing. This palm-tree, with its large shining leaves, folded like a fan, preserves a beautiful verdure at the period of the greatest drought. The mere sight of it pro- auces an agreeable sensation of coolness, and when loaded with scaly fruit, it contrasts singularly with the mournful aspect of the palma de cobija, the foliage of which is always grey and covered with dust. The Llaneros believe that the former attracts the vapours in the air ; J and that for this reason, water is constantly found at its foot, when dug for to a certain depth. The effect is confounded with the cause. The moriche grows best in moist places ; and it may rather be said that the water attracts the tree. The natives of the Orinoco, by analogous reasoning, admit, that the great serpents contribute to preserve humidity in a province. " lou would look in vain for water-serpents," said an old * This palm-tree of the plains must not be confounded with the palma real of Caracas and of Curiepe, with pinnate leaves. t Perhaps an Aipkanes. j If the head of the moriche were better furnished with leaves than it generally is, we might perhaps admit that the soil round the tree pre- serves its humidity through the influence of the shade. 108 OKIGIN OF TUE LLANO8. Indian of Javita to us gravely, " where there are nc marshes j because the water ceases to collect when you imprudently kill the serpents that attract it." We suffered greatly from the heat in crossing the Mesa de Calabozo. The temperature of the air augmented sensibly every time that the wind began to blow. The air was loaded with dust ; and during these gusts the thermometer rose to 40° or 41°. We went slowly forward, for it would have been dangerous to leave the mules that carried our instruments. Our guides advised us to fill our hats with the leaves of the rhopala, to diminish the action of the solar rays on the hair and the crown ol the head. We found relief from this expedient, which was particularly agreeable, when we could procure the thick leaves of the pothos or some other similar plant. It is impossible to cross these burning plains, without inquiring whether they have always been in the same state ; or whether they have been stripped of their vegetation by some revolution of nature. The stratum of mould now found on them is in fact very thin. The natives believe that the palmares and the cJiaparales (the little groves of palm-trees and rhopala) were more frequent and more exten- sive before the arrival of the Spaniards. Since the Llanos have been inhabited and peopled with cattle become wild, the savannah is often set on fire, in order to ameliorate the pasturage. Groups of scattered trees are accidently destroyed with the grasses. The plains were no doubt less bare in the fifteenth century, than they now are ; yet the first Conquistadores, who came from Coro, described them then as savannahs, where nothing could be perceived but the sky and the turf, generally destitute of trees, and dif- ficult to traverse on account of the reverberation of heat from the soiL Why does not the great forest of the Orinoco extend to the north, on the left bank of that river ? Why does it not fill that vast space that reaches as far as the Cordillera of the coast, and which is fertilized by numerous rivers ? These questions are connected with all that relates to the history of our planet. If, indulging in geologica/ reveries, we suppose that the steppes of America, and the desert of Sahara, have been stripped of their vegetation bj an irruption of the ocean, or that they formed originally tm FTTMBERS OF THE WILD CATTLE. 109 bottom of an inland sea, we may conceive that thousands of years have not sufficed for the trees and shrubs to advance from the borders of the forests, from the skirts of the plains either naked or covered with turf, toward the centre, and darken so vast a space with their shade. It is more difficult to explain the origin of bare savannahs, encircled by forests, than to recognize the causes that maintain forests and savan- nahs within their ancient limits, like continents and seas. We found the most cordial hospitality at Calabozo, in the house of the superintendent of the royal plantations, Don Miguel Cousin. The town, situated between the banks of the Guarico and the Uritucu, contained at this period only five thousand inhabitants; but everything denoted increasing prosperity. The wealth of most of the inhabitants consists in herds, under the management of farmers, who are called hater os, from the word hato, which signifies in Spanish a house or farm placed in the midst of pastures. The scat- tered population of the Llanos being accumulated on certain points, principally around towns, Calabozo reckons already five villages or missions in its environs. It is computed, that 98,000 head of cattle wander in the pastures nearest to the town. It is very difficult to form an exact idea of the herds contained in the Llanos of Caracas, Barce- lona, Cumana, and Spanish Guiana. M. Depons, who lived in the town of Caracas longer than I, and whose statis- tical statements are generally accurate, reckons in those Vhst plains, from the mouths of the Orinoco to the lake of Maracaybo, 1,200,000 oxen, 180,000 horses, and 90,000 mules. He estimates the produce of these herds at 5,000,000 francs ; adding to the value of the exportation the price of the hides consumed in the country. There exist, it is believed, in the Pampas of Buenos Ayres, 12,000,000 cows, and 3,000,000 horses, without comprising in this enume- meration the cattle that have no acknowledged proprietor. 1 shall not hazard any general estimates, which from their nature are too uncertain; but shall only observe that, in the Llanos of Caracas, the proprietors of the great hatos are entirely ignorant of the number of the cattle they possess. They only know that of the young cattle, which are branded every year with a letter or mark peculiar to each herd. The richest proprietors mark as many as 14,000 head every 110 EXPORTATION OF HIJ>EB. year; and sell to the number of five or six thousand According to official documents, the exportation of hides from the whole capitania-general of Caracas amounted annually to 174,000 skins of oxen, and 11,500 of goats. When we reflect, that these documents are taken from the books of the custom-houses, where no mention is made of the fraudulent dealings in hides, we are tempted to believe that the estimate of 1,200,000 oxen wandering in the Llanos, from the Rio Carony and the Guarapiche to the lake of Maracaybo, is much underrated. The port of La Gruayra alone exported annually from 1789 to 1792, 70,000 or 80,000 hides, entered in the custom-house books, scarcely one-fifth of which was sent to Spain. The exportation from Buenos Ayres, at the end of the eighteenth century, was, according to Don Felix de Azara, 800,000 skins. The hides of Caracas are preferred in the Peninsula to those of Buenos Ayres; because the latter, on account of a longer passage, undergo a loss of twelve per cent, in the tanning. The southern part of the savannahs, commonly called the Upper Plains (Llanos de arriba), is very productive in mules and oxen ; but the pasturage being in general less good, these animals are obliged to be sent to other plains to be fattened before they are sold. The Llano de Monai, and all the Lower Plains (Llanos de abaxo), abound less in herds, but the pastures are so fertile, that they furnish meat of an excellent quality for the supply of the coast. The mules, which are not fit for labour before the fifth year, are pur- chased on the spot at the price of fourteen or eighteen pias- tres. The horses of the Llanos, descending from the fine Spanish breed, are not very large ; they are generally of a uniform colour, brown bay, like most of the wild animals. Suffering alternately from drought and floods, tormented by the stings of insects and the bites of the large bats, they lead a sorry life. After having enjoyed for some months the care of man, their good qualities are developed. Here there are no sheep : we saw flocks only on the table-land of Quito. The Tiatos of oxen have suffered considerably of late from troops of marauders, who roam over the steppes killing the animals merely to take their hides. This robbery has in- creased since the trade of the Lower Orinoco has become 5TJMBEB OF EUBOPEAtf CATTLE. Ill more flourishing. For half a century, the banks of that great river, from the mouth of the Apure as far as Angostura, were known only to the missionary-monks. The exportata- tion of cattle took place from the ports of the northern coast only, viz. from Cumana, Barcelona, Burburata, and Porto Cabello. This dependence on the coast is now much dimi- nished. The southern part of the plains has established an internal communication with the Lower Orinoco ; and this trade is the in ore brisk, as those who devote themselves to it easily escape the trammels of the prohibitory laws. The greatest herds of cattle in the Llanos of Caracas are those of the Jiatos of Merecure, La Cruz, Belen, Alta Gracia, and Pavon. The Spanish cattle came from Coro and Tocuyo into the plains. History has preserved the name of the colonist who first conceived the idea of peopling these pas- turages, inhabited only by deer, and a large species of cavy. Christoval Kodriguez sent the first horned cattle into the Llanos, about the year 1548. He was an inhabitant of the town of Tocuyo, and had long resided in New Grenada. When we hear of the ' innumerable quantity ' of oxen, horses, and mules, that are spread over the plains of Ame- rica, we seem generally to forget that in civilized Europe, on lands of much less extent, there exist, in agricultural countries, quantities no less prodigious. France, accord- ing to M. Peuchet, feeds 6,000,000 large horned cattle, of which 3,500,000 are oxen employed in drawing the plough. In the Austrian monarchy, the number of oxen, cows, and calves, has been estimated at 13,400,000 head. Paris alone consumes annually 155,000 horned cattle. Germany receives 150,000 oxen yearly from Hungary. Domestic animals, collected in small herds, are considered by agrici J- tural nations as a secondary object in the riches of the state. Accordingly they strike the imagination much less than those wandering droves of oxen and horses which alone fill the uncultivated tracts of the New World. Civilization and social order favour alike the progress of population, and the multiplication of animals useful to man. We found at Calabozo, in the midst of the Llanos, an electrical machine with large plates, electrophori, batteries, * The thick-nosed tapir, or river cavy (C»iia capyban J, ealtad tkiy*irt in those countries. 112 A. SCIENTIFIC NATIVE. electrometers; an apparatus nearly as complete as our first scientific men in Europe possess. All these articles had not been purchased in the United States; they were the work of a man who had never seen any instrument, who had no person to consult, and who was acquainted with the phenomena of electricity only by reading the treatise of De Lafond, and Franklin's Memoirs. Sefior Carlos del Pozo, the name of this enlightened and ingenious man, had begun to make cylindrical electrical machines, by employing large glass jars, after having cut off the necks. It was only within a few years he had been able to procure, by way of Philadelphia, two plates, to construct a plate machine, and fco obtain more considerable effects. It is easy to judge what difficulties Sefior Pozo had to encounter, since the first works upon electricity had fallen into his hands, and that he had the courage to resolve to procure himself, by hia own industry, all that he had seen described in his books. Till now he had enjoyed only the astonishment and admi- ration produced by his experiments on persons destitute of all information, and who had never quitted the solitude of the Llanos; our abode at Calabozo gave him a satisfaction altogether new. It may be supposed that he set some value on the opinions of two travellers who could compare his apparatus with those constructed in Europe. I had brought with me electrometers mounted with straw, pith-balls, and gold-leaf; also a small Ley den jar which could be charged by friction according to the method of Ingenhousz, and which served for my physiological experiments. Sefior del Pozo could not contain his joy on seeing for the first time instruments which he had not made, yet which appeared to be copied from his own. "We also showed him the effect of the contact of heterogeneous metals on the nerves of frogs. The name of Gralvani and Volta had not previously been heard in those vast solitudes. Next to his electrical apparatus, th* work of the industry and intelligence of an inhabitant of the Llanos, nothing at Calabozo excited in us so great an interest as the gymnoti, which are animated electrical apparatuses. I was impatient, from the time of my arrival at Cuinana, to procure electrical eels. We had been promised them often, but our ho oca had always been disappointed Money loses its value aa ETJBCTRICJLL FISHES. 118 you with di aw from the coast; and how is the imperturbablo apathy of the ignorant people to be vanquished, when they are not excited by the desire of gain ? The Spaniards confound all electric fishes under the name of tembladores* There are some of these in the Caribbean Sea, on the coast of Cumana. The Guayquerie Indians, who are the most skilful and active fishermen in those parts, brought us a fish, which, they said, benumbed their nands. This fish ascends the little river Manzanares. It is a new species of ray, the lateral spots of which are scarcely visible, and which much resembles the torpedo. The torpedos, which are furnished with an electric organ ex- ternally visible, on account of the transparency of the skin, form a genus or subgenus different from the rays properly BO called.f The torpedo of Cumana was very lively, very energetic in its muscular movements, and yet the electric shocks it gave us were extremely feeble. They became stronger on galvanizing the animal by the contact of zinc and gold. Other tembladores, real gymnoti or electric eels, inhabit the Rio Colorado, the Guarapiche, and several little streams which traverse the Missions of the Chayma Indians. They abound also in the large rivers of America, the Ori- noco, the Amazon, and the Meta; but the force of the cm-rents and the depth of the water, prevent them from being caught by the Indians. They see these fish less fre- quently than they feel shocks from them when swimming or bathing in the river. In the Llanos, particularly in the environs of Calabozo, between the farms of Morichal and the Upper and Lower Missions, the basins of stagnant water and the confluents of the Orinoco (the Rio Guarico and the caTws Rastro, Berito, and Paloma) are filled with electric eels. We at first wished to make our experiments in the house we inhabited at Calabozo ; but the dread of the ihocks caused by the gymnoti is so great, and so exag- • Literally " tremblers," or "producers of trembling." t Cuvier, Regne Animal, vol. ii.

This fear of the Indians is the more 2xtrordinary, as they do not attempt to adopt precautions in which they profess to have great confidence. When interrogated on the effect of the tembladores, they never fail to tell the Whites, that they may be touched with impunity while you are chewing tobacco. This supposed influence of tobacco on animal electricity is as general on the continent of South America, as the belief among mariners of the effect of garlic and tallow on the magnetic needle. Impatient of waiting, and having obtained very uncertain results from an electric eel which had been brought to us alive, but much enfeebled, we repaired to the Carlo de Bera, to make our experiments in the open air, and at the edge of the water. We set off on the 19th of March, at a very early hour, for the village of Rastro ; thence we were conducted by the Indians to a stream, which, in the time of drought, forms a basin of muddy water, surrounded by fine trees,* the clusia, the amyris, and the mimosa with fragrant flowers. To catch the gymnoti with nets is very difficult, on account of the extreme agility of the fish, which bury themselves in the mud. We would not employ the barbasco, that is to say, the roots of the Piscidea erithyrna, the Jacquinia armillaris, and some species of phyllanthus, which thrown into the pool, intoxicate or benumb the eels. These methods have the effect of enfeebling the gymnoti. The Indians therefore told us that they would "fish with horses," (embarbascar con cuballos.t) We found it difficult to form an idea of this extraordinary manner of fishing; but we soon saw our guides return from the savannah, which they had been scouring for wild horses and mules. They brought about thirty with them, which they forced to enter the pool. The extraordinary noise caused by the horses' hoofs, makes the fish issue from the mud, and excites them to the attack. These yellowish and livid eels, resembling large * Amyris lateriflora, A. coriacea, I.aurus pichurin, Myroxylon secun- dum, Malpighia reticulata. f Meaning tc excite the fish by horses. 8INQULAB MET1IOD OF FI8HIW3. 115 aquatic serpents, swim on the surface of the water, and crowd under the bellies of the horses and mules. A contest between animals of so different an organization presents a very striking spectacle. The Indians, provided with harpoons and long slender reeds, surround the pool closely ; ana some climb up the trees, the branches of which extend horizontally over the surface of the water. By their wild cries, and the length of their reeds, they prevent the horses from running away and reaching the bank of the pool. The eels, stunned by the noise, defend themselves by the repeated discharge of their electric batteries. For a long interval they seem likely to prove victorious. Several horses sink beneath the violence of the invisible strokes which they receive from all sides, in organs the most essential to life ; and stunned by the force and frequency of the shocks, they disappear under the water. Others, panting, with mane erect, and haggard eyes expressing anguish and dismay, raise themselves, and endeavour to nee from the storm by which they are overtaken. They are driven back by the Indians into the middle of the water; but a small number succeed in eluding the active vigilence of the fishermen. These regain the shore, stumbling at every step, and stretch themselves on the sand, exhausted with fitigue, and with limbs benumbed by the electric shocks of the gymnoti. In less than five minutes two of our horses were drowned. The eel being five feet long, and pressing itself against the belly of the horses, makes a discharge along the whole extent of its electric organ. It attacks at once the heart, the in- testines, and the caeliac fold of the abdominal nerves. It is natural that the effect felt by the horses should be more powerful than that produced upon man by the touch of the same fish at only one of his extremities. The horses are probably not killed, but only stunned. They are drowned from the impossibility of rising amid the prolonged struggle between the other horses and the eels. We had little doubt that the fishing would terminate by killing successively all the animals engaged ; but by degivtf the impetuosity of this unequal combat diminished, and the wearied gymnoti dispersed. They require a long rest, ami Abundant nourishment, to repair the galvanic force which i a 116 SIZE OF THE GYMITOTUa. they have lost.* The mules and horses appear less fright- ened; their manes are no longer bristled, and their eyes express less dread. The gymnoti approach timidly the edge of the marsh, where they are taken by means of small harpoons fastened to long cords. When the cords are very dry the Indians feel no shock in raising the fish into the air. In a few minutes we had five large eels, most of which were but slightly wounded. Some others were taken, by the same means, towards evening. The temperature of the waters in which the gymnoti habitually Hve, is from 26° to 27°. Their electric force diminishes it is said, in colder waters ; and it is remarkable that, in general, animals endowed with electromotive organs, the effects of which are sensible to man, are not found in the air, but in a fluid that is a conductor of electricity. The gymnotus is the largest of electrical fishes. I measured some that were from five feet to five feet three inches long ; and the Indians assert that they have seen them still larger. We found that a fish of three feet ten inches long weighed twelve pounds. The transverse diameter of the body, with- out reckoning the anal fin, which is elongated in the form of a keel, was three inches and a half. The gymnoti of the Cano de Bera are of a fine olive-green. The under part of the head is yellow mingled with red. Two rows of small yellow spots are placed symmetrically along the back, from the head to the end of the tail. Every spot contains an excretory aperture. In consequence, the skin of the animal is constantly covered with a mucous matter, which, as Volta has proved, conducts electricity twenty or thirty times better than pure water. It is in general somewhat remark- able, that no electric fish yet discovered in the different parts of the world, is covered with scales.f * The Indiana assured us that when the horses are made to run two days successively into the same pool, none are killed the secoud day. See, on the fishing for gymnoti, " Views of Nature." (Bohn's ed., p. 18.) f We yet know with certainty only seven electrir fishes ; Torpedo narke, Risso, T. unimaculata, T. marmorata, T. gaivanii, Silurus elec- tricus, Tetraodon electricus, Gymnotus electricus. It appears uncertain whether the Trichiurus indicus has electrical properties or not. (See Cuvier's Regne Animal, vol. ii.) But the genus Torpedo, very different from that of the rays properly so called, has numerous species in the equatorial seas; and it is probable that there exist several gyu.noti RESPIRATION OF FISHES. 117 The gymnoti, like our eels, are fond of swallowing and breathing air on the surface of the water ; but we must not thence conclude that the fish would perish if it could not come up to breathe the air. The European eel will creep during the night upon the grass ; but I have seen a very vigorous gymnotus that had sprung out of the water, die on the ground. M. Proven9al and myself have proved by our researches on the respiration of fishes, that their humid bronchia) perform the double function of decomposing the atmospheric air, and of appropriating the oxygen contained in water. They do not suspend their respiration in the air; but they absorb the oxygen like a reptile furnished with lungs. It is known that carp may be fattened by being fed, out of the water, if their gills are wet from time to time with humid moss, to prevent them from becoming dry. Fish separate their gill-covers wider in oxygen gas than in water. Their temperature however, does not rise ; and they dve the same length of time in pure vital air, and in a mixture of ninety parts nitrogen and ten oxygen. We found that tench placed under inverted jars filled with air, absorb half a cubic centimetre of oxygen in an hour. This action takes place in the gills only ; for fishes on which a collar of cork has been fastened, and leaving their head out of the jar filled with air, do not act upon the oxygen by the rest of their body. The swimming-bladder of the gymnotus is two feet five inches long in a fish of three feet ten inches.f It is sepa- rated by a mass of fat from the external skin ; and rests upon the electric organs, which occupy more than two-thirds of specifically different. The Indians mentioned to us a black and very powerful species, inhabiting the marshes of the Apure, which never attains a length of more than two feet, but which we were not able to procure. The raton of the Rio de la Magdalena, which I have described under the name of Gymnotus aequilabiatus (Observations de Zoologie, vol. i.) forms a particular sub-genus. This is a Carapa, not scaly, and without an electric organ. This organ is also entirely wanting in the Brazilian Carapo, and iu all the rays which were carefully examined bf Cuvier. f Cuvier has shown that in the Gymnotus electricus there exists, oesides the large swimming-bladder, another situated before it, and much smaller. It looks like the bifuicated swimming-bladder in the Gymnotui 118 DAJTGEEOrS EFFECTS OF THE SHOCK. the animal's body. The same vessels which penetrate be- tween the plates or leaves of these organs, and which cover them with blood when they are cut transversely, also send out numerous branches to the exterior surface of the air- bladder. I found in a hundred parts of the air of the swim- ming-bladder four of oxygen and ninety-six of nitrogen. The medullary substance of the brain displays but a feeble analogy with the albuminous and gelatinous matter of the electric organs. But these two substances have in common the great quantity of arterial blood which they receive, and which is deoxidated in them. We may again remark, on this occasion, that an extreme activity in the functions of the brain causes the blood to flow more abundantly towards the head, as the energy of the movement of the muscles accelerates the deoxidation of the arterial blood. What a contrast between the multitude and the diameter of the blood-vessels of the gynmotus, and the small space occupied by its muscular system ! This contrast reminds the observer, that three functions of animal life, which appear in other re- spects sufficiently distinct, — the functions of the brain, those of the electrical organ, and those of the muscles, all require the afflux and concourse of arterial or oxygenated blood. It would be temerity to expose ourselves to the first shocks of a very large and strongly irritated gymnotus. If by chance a stroke be received before the fish is wounded or wearied by long pursuit, the pain and numbness are so violent that it is impossible to describe the nature of the feeling they excite. 1 do not remember having ever received from the mscharge of a large Leyden jar, a more dreadful shock than that which I experienced by imprudently placing both my feet on a gymnotus just taken out of the water. I was affected during the rest of the day with a violent pain in the knees, and in almost every joint. To be aware of the difference that exists between the sensation produced by the Voltaic battery and an electric fish, the latter should be touched when they are in a state of extreme weakness. The gymnoti arid the torpedos then cause a twitching of the muscles, which is propagated from the part that rests on the electric organs, as far as the elbow. We seem to feel, at every stroke, an internal vibration, which lasts two or three seconds, and is followed by a painful numbness. Accord- SUPPOSED REMEDIAL VIRTUES. 119 ingly, the Tamanac Indians call the gymnotus, in their expressive language, arimna, which means ' something that deprives of motion.' The sensation caused bv the feeble shocks of an electric eel appeared to me analogous to that painful twitching with which I have been seized at each contact of two heterogeneous metals applied to wounds which I had made on my back by means of cantharides. This difference of sensation between the effects of electric fishes and those of a Voltaic battery or a Leyden jar feebly charged has etruck every observer; there is, however, nothing in this contrary to the supposition of the identity of electricity and the galvanic action of fishes. The electricity may be the same; but its effects will be variously modified by the dis- position of the electrical apparatus, by the intensity of the fluid, by the rapidity of the current, and by the particular mode of action. In Dutch Guiana, at Demerara for instance, electric eels were formerly employed to cure paralytic affections. At a time when the physicians of Europe had great confi- dence in the effects of electricity, a surgeon of Essequibo, named Van der Lott, published in Holland a treatise on the medical properties of the gymnotus. These electric remedies are practised among the savages of America, as they were among the Greeks. We are told by Scribonius Largus, Galen, and Dioscorides, that torpedos cure the head- ache and the gout. I did not hear of this mode of treat- ment in the Spanish colonies which I visited ; and I can assert that, after having made experiments during four hours successively with gymnoti, M. Bonpland and myself felt, till the next day, a debility in the muscles, a pain in the joints, and a general uneasiness, the effect of a strong irritation of the nervous system. The gymnotus is neither a charged conductor, nor a battery, nor an electromotive apparatus, the shock of which is received every time they are touched with one hand, or when both hands are applied to form a conducting circle between the opposite poles. The electric action of the fish depends entirely on its will; because it does not keep ita rlectric organs always charged, or whether by the secretion of some fluid, or by any other means alike mysterious to us, 120 EXPERIMENTS ON THE GYMNOTUS. it be capable of directing the action of its organs to an external object. We often tried, both insulated and other- wise, to touch the fish, without feeling the least shock. When M. Bonpland held it by the head, or by the middle of the body, while I held it by the tail, and, standing on the moist ground, did not take each other's hand, one of us received shocks, which the other did not feel. It depends upon the gymnotus to direct its action towards the point where it finds itself most strongly irritated. The discharge is then made at one point only, and not at the neighbouring points. If two persons touch the belly of the fish with their fingers, at an inch distance, aud press it simultaneously, sometimes one, sometimes the other, will receive the shock. In the same manner, when one insulated person holds the tail of a vigorous gymnotus, and another pinches the gills or pectoral fin, it is often the first only by whom the shock is received. It did not appear to us that these differences could be attributed to the dryness or moisture of our hands, or to their unequal conducting power. The gymnotus seemed to direct its strokes sometimes from the whole sur- face of its body, sometimes from one point only. This effect indicates less a partial discharge of the organ com- posed of an innumerable quantity of layers, than the faculty which the animal possesses, (perhaps by the instantaneous secretion of a fluid spread through the cellular membrane,) of establishing the communication between its organs and the skin only, in a very limited space. Nothing proves more strongly the faculty, which the gymnotus possesses, of darting and directing its stroke at will, than the observations made at Philadelphia and Stockholm,* on gymnoti rendered extremely tame. When * By MM. Williamson and Fahlberg. The following account is given by the latter gentleman. " The gymnotus sent from Surinam to M. Norderhng, at Stockholm, lived more than four months in a state of perfect health. It was twenty-seven inches long ; and the shocks it gave were so violent, especially in the open air, that I found scarcely any means of protecting myself by non-conductors, in transporting the fish from one place to another. Its stomach being very small, it ate little at a time, but fed often. It approached living fish, first sending them fronn afar a shock, the energy of which was proportionate to the size ot the prey. The gymnotus seldom failed in its aim ; one single stroke was almost alwaj 3 sufficient to overcome the resistance which the strata HABITS OF THE ELECTlilC EEL. 121 they had been made to fast a long time, they killed small fishes put into the tub. They acted from a distance ; that is to say, their electrical shock passed through a very thick stratum of water. We need not be surprised that what waa observed in Sweden, on a single gymnotus only, we could Dot perceive in a great number of individuals in their native country. The electric action of animals being a vital action, and subject to f;heir will, it does not depend solely on their state ot health and. vigour. A gymnotus that has been kept a long time in captivity, accustoms itself to the im- prisonment to which is is reduced; it resumes by degrees the same habits in the tub, which it had in the rivers and marshes. An electrical eel was brought to me at Calabozo : it had been taken in a net, and consequently having no wound. It ate meat, and terribly frightened the little tor- toises and frogs which, not aware of their danger, placed themselves on its back. The frogs did not receive the stroke till the moment when they touehed the body of the gymnotus. When they recovered, they leaped out of the tub ; and when replaced near the fish, they were frightened at the mere sight of it. We then observed nothing that indicated an action at a distance ; but our gymnotus, recently taken, was not yet sufficiently tame to attack and devour frogs. On approaching the finger, or the metallic points, very close to the electric organs, no shock was felt. Perhaps the animal did not perceive the proximity of a foreign body ; or, if it did, we must suppose that in the commencement of its captivity, timidity prevented it from darting forth its energetic strokes except when strongly irritated by an immediate contact. The gymnotus being immersed in water, I placed my hand, both armed and unarmed with metal, within a very small distance from the electric organs; yet the strata of water transmitted no shock, while M. Bonpland irritated the animal strongly by an immediate contact, and of water, more or leas thick according to the distance, opposed to the electrical current. When very much pressed by hunger, it sometimes directed the shocks against the person who daily brought its food of boiled meat. Persons afflicted with rheumatism rame to touch it in hopes of being cured. They took it at once by the neck and tail : the shocks were in this case stronger than when touched with one hand only. It Almost entirely lost its electrical power a short time before its death.' 122 SIMILAEITT OF THE ELECTRIC ACTIOW. received some very violent shocks. Had we placed a very delicate electroscope in the contiguous strata of water, it might possibly have deen influenced at the moment when the gymnotus seemed to direct its stroke elsewhere, Pre- pared frogs, placed immediately on the body of a torpedo, experience, according to Galvani, a strong contraction at every discharge of the fish. The electrical organ of the gymnoti acts only under the immediate influence of the brain and the heart. On cutting a very vigorous fish through the middle of the body, the fore part alone gave shocks. These are equally strong in whatever part of the body the fish is touched; it is most disposed, however, to emit them when the pectoral fin, the electrical organ, the lips, the eyes, or the gills, are pinched. Sometimes the animal struggles violently with a person holding it by the tail, without communicating the least shock. Nor did I feel any when I made a slight incision near the pectoral fin of the fish, and galvanized the wound by the contact of two pieces of zinc and silver. The gym- notus bent itself convulsively, and raised its head out of the water, as if terrified by a sensation altogether new ; but I felt no vibration in the hands which held the two metals. The most violent muscular movements are not always ac- companied by electric discharges. The action of the fish on the human organs is transmitted and intercepted by the same bodies, that transmit and inter- cept the electrical current of a conductor charged by a Leyden jar, or Voltaic battery. Some anomalies, which we thought we observed, are easily explained, when we recollect that even metals (as is proved from their ignition when exposed to the action of the battery) present a slight obstacle to the passage of electricity ; and that a bad con- ductor annihilates the eifect, on our organs, of a feeble electric charge, whilst it transmits to us the effect of a very strong one. The repulsive force which zinc and silver exercise together being far superior to that of gold and silver, I have found that when a frog, prepared and armed with silver, is galvanized under water, the conducting arc of zinc produces contraction as soon as one of its extre- mities approaches the muscles within three lines distance ; while an arc :? gold does not excite the organs, when the TEAN8MI8SION OF THE SHOCK. 125 stratum of water between the gold and the muscles? is more than half a Hue thick. In the same manner, by employing a conducting arc composed of two pieces of zinc and silver soldered together endways; and resting, as before, one of the extremities of the metallic circuit on the femoral nerve, it is necessary, in order to produce contractions, to bring the other extremity of the conductor nearer a ad nearer to the muscles, in proportion as the irritability of the organs diminishes. Toward the end of the experiment the slightest stratum of water prevents the passage of the electrical cur- rent, and it is only by the immediate contact of the arc with the muscles, that the contractions take place. These effects are, however, dependent on three variable circumstances; the energy of the electromotive apparatus, the conducti- bility of tlie medium, and the irritability of the organs which receive the impressions: it is because experiments have not been sufficiently multiplied with a view to these three variable elements, that, in the action of electric eels and torpedos, accidental circumstances have been taken for absolute conditions, without which the electric shocks are not felt. In wounded gymnoti, which give feeble but very equal shocks, these shocks appeared to us constantly stronger on touching the body of the fish with a hand armed with metal, than with the naked hand. They are stronger also, when, instead of touching the fish with one hand, naked, or armed witli metal, we press it at once with both hands, either naked or armed. These differences become sensible only when one has gymnoti enough at disposal to be able to choose the weakest ; and when the extreme equality of the electric discharges admits of distinguishing between the sen- sations felt alternately by the hand naked or armed with a nu-tal, by one or both hands naked, and by one or both hands armed with metal. It is also in the case only of small shocks, feeble and uniform, that they are more sen- sible on touching the gymnotus with one hand (without forming a chain) with zinc, than with copper or iron. Resinous substances, glass, very dry wood, horn, and even bones, which are generally believed to be good conductors, prevent the action of the gymnoti from being transmitted to man. I was surprised at no*: feeling the least shock o- 124 ABSENCE OF ATTRACTION. pressing wet sticks of sealing-wax against the organs of the fish, while the same animal gave me the most violent strokes, when excited bv means of a metallic rod. M. Bon- pland received shocks, when carrying a gymnotus on two cords of the fibres of the palm-tree, which appeared to us extremely dry. A strong discharge makes its way tli rough very imperfect conductors. Perhaps also the obstacle which the conductor presents renders the discharge more painful. I touched the gymnotus with a wet pot of brown clay, without effect ; yet I received violent shocks when 1 carried the gymnotus in the same pot, because the contact was greater. When two persons, insulated or otherwise, hold each other's hands, and only one of these persons touches the fish with the hand, either naked or armed with metal, the shock is most commonly felt by both at once. However, it sometimes happens that, in the most severe shocks, the person who comes into immediate contact with the fish alone feels them. "When the gymnotus is exhausted, or in a very reduced state of excitability, and will no longer emit strokes on being irritated with one hand, the shocks are felt in a very vivid manner, on forming the chain, and em- ploying both hands. Even then, however, the electric shock takes place only at the will of the animal. Two persons, one of whom holds the tail, and the other the head, cannot, by joining hands and forming a chain, force the gymnotus to dart his stroke. Though employing the most delicate electrometers ic various ways, insulating them on a plate of glass, and receiv- ing very strong shocks which passed through the electro- meter, I could never discover any phenomenon of attraction or repulsion. The same observation was made by M. Fahl- berg at Stockholm. That philosopher, however, has seen an electric spark, as Walsh and Irigenhousz had ^ before him, in London, by placing the gymnotus in the air, and interrupting the conducting chain by two gold leaves pasted upon glass, and a line distant from each other. No person, on the contrary, has ever perceived a spark issue from the body of the fish itself. We irritated it for a long time during the night, at Calabozo, in perfect darkness, without observing any luminous appearance. Having placed four 1XPEKIMENTS ON THE TORPEDO. 125 gymnoti, of unequal strength, in such a manner as to receive the shocks of the most vigorous fish by contact, that is to say, by touching only one of the other fishes, I did not observe that these last were agitated at the moment when the current passed their bodies. Perhaps the current did not penetrate below the humid surface of the skin. "We will not, however, conclude from this, that the gymnoti are insensible to electricity ; and that they cannot fight with each other at the bottom of the pool's. Their nervous system must be subject to the same agents as the nerves of other animals. I have indeed seen, that, on laying open their nerves, they undergo muscular contractions at the mere contact of two opposite metals ; and M. Fahlberg, of Stockholm, found that his gymnotus was convulsively agi- tated when placed in a copper vessel, and feeble discharges from a Leyden jar passed through its skin. After the experiments I had made on gymnoti, it became highly interesting to me, on my return to Europe, to ascer- tain with precision the various circumstances in which another electric fish, the torpedo of our seas, gives or does not give shocks. Though this fish had been examined by numerous men of science, I found all that had been pub- lished on its electrical effects extremely vague. It has been very arbitrarily supposed, that this fish acts like a Leyden jar, which may be discharged at will, by touching it with Doth hands; and this supposition appears to have led into error observers who have devoted themselves to researches of this kind. M. Gay-Lussac and myself, during our journey to Italy, made a great number of experiments on torpedoa •n in the gulf of Naples. These experiments furnish many results somewhat different from those I collected on the gymnoti. It is probable that the cause of these anoma- lies is owing rather to the inequality of electric power in the two fishes, than to the different disposition of their organs. Though the power of the torpedo cannot be compared with that of the gymnotus, it is sufficient to cause very painful sensations. A person accustomed to electric shocks can with difficulty hold in his hands a torpedo of twelve or fourteen inches, and in possession of all its vigour. When the torpedo gives only very feeble strokes under water, 126 THE SHOCJy A VITAL ACTION. they become more sensib'e if the animal be raised above the surface. I have often observed the same phenomenon in experimenting on frogs. The torpedo moves the pectoral fins convulsively every time it emits a stroke; and this stroke is more or lesa painful, according as the immediate contact takes place by a greater or less surface. We observed that the gymnotus gives the strongest shocks without making any movement with the eyes, head, or fins.* Is this difference caused by the position of the electric organ, which is not double in the gymnoti? or does the movement of the pectoral fins of the torpedo directly prove that the fish restores the electrical equilibrium by its own skin, dis- charges itself by its own body, and that we generally feel only the effect of a lateral shock ? We cannot discharge at will either a torpedo or a gym notus, as we discharge at will a Leyden jar or a Voltaic battery. A shock is not always felt, even on touching the electric fish with both hands. We must irritate it to make it give the shock. This action in the torpedos, as well as in the gymnoti, is a vital action ; it depends on the will only of the animal, which perhaps does not always keep its elec- tric organs charged, or does not always employ the action of its nerves to establish the chain between the positive and Degative poles. It is certain that the torpedo gives a long series of shocks with astonishing celerity ; whether it is that the plates or Iamina3 of its organs are not wholly exhausted, or that the fish recharges them instantaneously. The electric stroke is felt, when the animal is disposed to give it, whether we touch with a single finger only one of the surfaces of the organs, or apply both hands to the two surfaces, the superior and inferior, at once. In either case it is altogether indifferent whether the person who touches the fish with one finger or both hands be insulated or not. All that has been said on the necessity of a communication with the damp ground to establish a circuit, is founded on inaccurate observations. M. Gay-Lussac made the important observation that when an insulated person touches the torpedo with one * The anal fin of the gymnoti only has a sensible motion when these fishes are excited under the belly, where the electric organ is placed. EFFECTS OT TABULATORS. 127 linger, it is indispensible that the contact be direct. The fish may with impunity be touched with a key, or any other metallic instrument; no shock is felt when a con- ducting or non-conducting body is interposed between the finger and the electrical organ of the torpedo. This cir- cumstance proves a great difference between the torpedo and the gymnotus, the latter giving his strokes through an iron rod several feet long. When the torpedo is placed on a metallic plate of very little thickness, so that the plate touches the inferior surface of the organs, the hand that supports the plate never feels any shock, though another, insulated person may excite the animal, and the convulsive movement of the pectoral fins may denote the strongest and most reiterated discharges. If, on the contrary, a person support the torpedo placed upon a metallic plate, with the left hand, as in the foregoing experiment, and the same person touch the superior surface of the electrical organ with the right hand, a strong shock is then felt in both arms. The sensation is the same when the fish is placed between two metallic plates, the edges of which do not touch, and the person applies both hands at once to these plates. The interposition of one metallic plate prevents the communication if that plate be touched with one hand only, while the interposition of two metallic plates does not prevent the shock when both hands are applied. In the latter case it cannot be doubted that the circulation of the fluid is established by the two arms. If, in this situation of the fish between two plates, there exist any immediate communication between the edges of these two plates, no shock takes place. The chain between the two surfaces of the electric organ is then formed by the plates, and the new communication, established by the contact of the two hands with the two plates, remains with- out effect. \Ve carried the torpedo with impunity between two plates of metal, and felt the strokes it gave only at the instant who- they ceased to touch each other at the Nothin-r in the torpedo or in the gymnotus indicates that the animal modifies the electrical state of the bodies by tthirh it is surrounded. The most delicate electrometer is no way affected in whatever manner it is employed, whether 128 ACTION OF THE BRAIN AND NEBVES. bringing it near the organs or insulating the fish, covering it with a metallic plate, and causing the plate to communi- cate by a conducting wire with the condenser of Volta, We were at great pains to vary the experiments by which we sought to render the electrical tension of the torpedo sensible ; but they were constantly without effect, and per- fectly confirmed what M. Bonpland and myself had observed respecting the gymnoti, during our abode in South America. Electrical fishes, when very vigorous, act with equal energy under water and in the air. This observation led us to examine the conducting property of water ; and we found that, when several persons form the chain between the superior and inferior surface of the organs of the torpedo, the shock is felt only when these persons join hands. The action is not intercepted if two persons, who support the torpedo with their right hands, instead of taking one another by the left hand, plunge each a metallic point into a drop of water placed on an insulating substance. On substituting flame for the drop of water, the communication is interrupted, and is only re-established, as in the gym- notus, when the two points immediately touch each other in the interior of the flame. We are, doubtless, very far from having discovered all the secrets of the electrical action of fishes which is modified by the influence of the brain and the nerves ; but the experiments we have just described are sufficient to prove that these fishes act by a concealed electricity, and by elec- tromotive organs of a peculiar construction, which are recharged with extreme rapidity. Yolta admits that the discharges of the opposite electricities in the torpedos and the gymnoti are made by their own skin, and that when we touch them with one hand only, or by moans of a metallic point, we feel the effect of a lateral shock, the electrical current not being directed solely the shortest way. When a Leyden jar is placed on a wet woollen cloth (which is a bad conductor), and the jar is discharged in such a manner that the cloth makes part of the chain, prepared frogs, placed at different distances, indicate by their contractions that the current spreads itself over the whole cloth in a thousand different ways. According to this analogy, the most violent shock givei* by the gymnotus at a distance SUPPOSED MAGNETIC PHENOMENA. 129 would be but a feeble part of the stroke which re-establishea the equilibrium in the interior of the fish.* As the gym- notus directs its stroke wherever it pleases, it must also be admitted that the discharge is not made by the whole skin at once, but that the animal, excited perhaps by the motion of a fluid poured into one part of the cellular membrane, establishes at will the communication between its organs and some particular part of the skin. It may be conceived that a lateral stroke, out of the direct current, must become imperceptible under the two conditions of a very weak discharge, or a very great obstacle presented by the nature and length of the conductor. Notwithstanding these con- siderations, it appears to me very surprising that shocks of the torpedo, strong in appearance, are not propagated to the hand when a very thin plate of metal is interposed betweeu it and the fish. Schilling declared that the gymnotus approached the magnet involuntarily. We tried in a thousand ways this supposed influence of the magnet on the electrical organs, without having ever observed any sensible effect. The fish no more approached the magnet, than a bar of iron not magnetic. Iron-filings, thrown on its back, remained motion- less. The gymnoti, which are objects of curiosity and of the the deepest interest to the philosophers of Europe, are #t once dreaded and detested by the natvies. They famish, indeed, in their muscular flesh, pretty good aliment; but the electric organ fills the greater part of their body, and this organ is slimy, and disagreeable to the taste; it is * The heterogeneous poles of the double electrical organs must exist ia each organ. Mr. Todd has recently proved, by experiments made on torpedos at the Cape of Good Hope, that the animal continues to give violent shocks when one of these organs is extirpated. On the contrary, all electrical action is stopped (and this point, as elucidated by Galvani, is of the greatest importance) if injury be inflicted on the brain, or if the nerves which supply the plates of the electrical organs be divided. In the latter case, the nerves being cut, and the brain left un- touched, the torpedo continues to live, and perform every muscular movement. A fish, exhausted by too numerous electrical discharges, iuffered much more than another fish deprived, by dividing the nerves, of any communication between the brain and the electromotive apparatus.

The presence of gymnoti is alsc considered as the principal cause of the want of fish in the ponds and pools of the Llanos. They, however, kill many more than they devour : and the Indians told us, that when young alligators and gymnoti are caught at the same time in very strong nets, the latter never show the slightest trace of a wound, because they disable the young alligators before they are attacked by them. All the inhabitants of the waters dread the society of the gymnoti. Lizards, tortoises, and frogs, seek pools where they are secure from the electric action. It became necessary to change the direction of a road near Uritucu, because the electric eels were so numerous in one river, that they every year killed a great number of mules, as they forded the water with their burdens. Though in the present state of our knowledge we may natter ourselves with having thrown some light on the extraordinary effects of electric fishes, yet a vast number of physical and physiological researches still remain to be made. The brilliant results which chemistry has obtained by means of the Voltaic battery, have occupied all observers, and turned attention for some time from the examinations of the phe- nomena of vitality. Let us hope that these phenomena, the most awful and the most mysterious of all, will in their turn occupy the earnest attention of natural philosophers. This hope will be easily realized if they succeed in procuring anew living gymnoti in some one of the great capitals of Europe. The discoveries that will be made on the electro- motive apparatus of these fish, much more energetic, and more easy of preservation, than the torpedos,* will extend * In order to investigate the phenomena of the living electromotive apparatus in its greatest simplicity, and not to mistake for general conditions circumstances which depend on the degree of energy of the electric organs, it is necessary to perform the experiments on those electrical fishes most easily tamed. If the gymnoti were not known, we might suppose, from the observations made on torpedos, that fishes can- not give their shocks from a distance through very thick strata of water, Or through a bar of iron, without forming a circuit. Mr. Williamson has felt strong shocks when he held only one hand in the water, and this band, without touching the gymnotus, was placed between it and the small fish towards which the stroke was directed from ten or fifteei incites distance.

It will perhaps be found that, in most animals, every contraction of the muscular fibre is preceded by a discharge from the nerve into the muscle ; and that the mere simple contact of heterogeneous substances is a source of move- ment and of life in all organized beings. Did an ingenious and lively people, the Arabians, guess from remote antiquity, that the same force which inflames the vault of Heaven in storms, is the living and invisible weapon of inhabitants of the waters? It is said, that the electric fish of the Nile bears a name in Egypt, that signifies thunder* "We left the town of Calabozo on the 24th of March, highly satisfied with our stay, and the experiments we had made on an object so worthy of the attention of physio- logists. I had besides obtained some good observations of the stars ; and discovered with surprise, that the errors of maps amounted here also to a quarter of a degree of lati- tude. No person had taken an observation before me on this spot ; and geographers, magnifying as usual the distance from the coast to the islands, have carried back beyond measure all the localities towards the south. As we advanced into the southern part of the Llanos, we found the ground more dusty, more destitute of herbage, and more cracked by the effect of long drought. The palm- trees disappeared by degrees. The thermometer kept, from eleven in the morning till sunset, at 34° or 35°. The calmer the air appeared at eight or ten feet high, the more we were enveloped in those whirlwinds of dust, caused by the little currents of air that sweep the ground. About four o'clock in the afternoon, we found a young Indian girl stretched upon the savannah. She was almost in a state of nudity, and appeared to be about twelve or thirteen years of age. Ex- hausted with fatigue and thirst, her eyes, nostrils, and mouth When the gymnotus was enfeebled by bad health, the lateral shock was imperceptible ; and in order to feel the shock, it was necessary to form a chain, and touch the fish with both hands at once. Cavendish, in his ingenious experiments on an artificial torpedo, had well remarked these differences, depending on the greater or less energy of the charge.

A pitcher, over- turned, and half filled with sand, was lying at her side. Happily one of our mules was laden with water ; and we roused the girl from her lethargic state by bathing her face, and forcing her to drink a few drops of wine. She was at first alarmed on seeing herself surrounded by so many per- sons ; but by degrees she took courage, and conversed with our guides. She judged, from the position of the sun, that she must have remained during several hours in that state of lethargy. We could not prevail on her to mount one of our beasts of burden, and she would not return to Uritucu, She had been in service at a neighbouring farm ; and she had been discharged, because at the end of a long sickness she was less able to work than before. Our menaces and prayers were alike fruitless ; insensible to suffering, like the rest of her race, she persisted in her resolution of going to one of the Indian Missions near the city of Calabozo. We removed the sand from her pitcher, and filled it with water. She resumed her way along the steppe, before we had re- mounted our horses, and was soon separated from us by a cloud of dust. During the night we forded the Rio Uritucu, which abounds with a breed of crocodiles remarkable for their ferocity. We were advised to prevent our dogs from going to drink in the rivers, for it often happens that the crocodiles of Uritucu come out of the water, and pursue dogs upon the shore. This intrepidity is so much the more striking, as at eight leagues distance, the crocodiles of the Rio Tisnao are extremely timid, and little dangerous. The manners of animals vary in the same species according to local circumstances difficult to be determined. We were shown a hut, or rather a kind of shed, in which our host of Calabozo, Don Miguel Cousin, had witnessed a very extra- ordinary scene. Sleeping with one of his friends on a bench or couch covered with leather, Don Miguel was awakened early in the morning by a violent shaking and a horrible noise. Clods of earth were thrown into the middle of the hut. Presently a young crocodile two or three feet long issued from under the bed, darted at a dog which lay on the threshold of the door, and, missing him in the impetuosity of his spring, ran towards the beach to gain the river. On 8UMMEU-SLEEP OF SNAKES. 133 examining the spot where the barbacoa, or couch, was placed, the cause of this strange adventure was easily discovered. The ground was disturbed to a considerable depth. It was dried mud, which had covered the crocodile in that state of lethargy, or summer-sleep, in which many of the species lie during the absence of the rains in the Llanos. The noise of men and horses, perhaps the smell of the dog, had aroused the crocodile. The hut being built at the edge of the pool, and inundated during part of the year, the crocodile had no doubt entered, at the time of the inundation of the savan- nahs, by the same opening at which it was seen to go out. The Indians often find enormous boas, which they call uji, or water-serpents,* in the same lethargic state. To reanimate them, they must be irritated, or wetted with water. Boas are killed, and immersed in the streams, to obtain, by means of putrefaction, the tendinous parts of the dorsal muscles, of which excellent guitar-strings are made at Galabozo, preferable to those furnished by the intestines of the alouate monkeys. The drought and heat of the Llanos act like cold upon animals and plants. Beyond the tropics the trees lose their leaves in a very dry air. Reptiles, particularly crocodiles and boas, having very indolent habits, leave with reluctance the basins in which they have found water at the period of great inundations. In proportion as the pools become dry, these animals penetrate into the mud, to seek that degree of humidity which gives flexibility to their skin and integuments. In this state of repose they are seized with stupefaction; but possibly they preserve a communication with the external air ; and, however little that communica- tion may be, it possibly suffices to keep up the respiration of an animal of the saurian family, provided with enormous pulmonary sacs, exerting no muscular motion, and in which almost all the vital functions are suspended. It is probable that the mean temperature of the dried mud, exposed to the solar rays, is more than 40°. When the north of Egypt, where the coolest month does not fall below L3'4°, was inhabited by crocodiles, they were often found torpid with cold. They were subject to a winter-sleep, like the Euro- * Oulcbra de ayua, named by the common people traga-venado, 'the •wallower of stags.'

If the hibernal lethargy be observed, both in cold-blooded and in hot- blooded animals, we shall be less surprised to learn, that these two classes furnish alike examples of a summer-sleep. In the same manner as the crocodiles of South America, the tanrecs, or Madagascar hedgehogs, in the midst of the torrid zone, pass three months of the year in lethargy. On the 25th of March we traversed the smoothest part of the steppes of Caracas, the Mesa de Pavones. It is entirely destitute of the corypha and moriche palm-trees. As far as the eye can reach, not a single object fifteen inches high can be discovered. The air was clear, and the sky of a very deep blue ; but the horizon reflected a livid and yellowish light, caused no doubt by the quantity of sand suspended in the atmosphere. "We met some large herds of cattle, and with them flocks of birds of a black colour with an olive shade. They are of the genus Croto- phaga,* and follow the cattle. We had often seen them perched on the backs of cows, seeking for gadflies and other insects. Like many birds of these desert places, they fear so little the approach of man, that children often catch them in their hands. In the valleys of Aragua, where they are very common, we have seen them perch upon the hammocks on which we were reposing, in open day. We discover, between Calabozo, Uritucu, and the Mesa de Pavones, wherever there are excavations of some feet deep, the geological constitution of the Llanos. A formation of red sandstone (ancient conglomerate) covers an extent of several thousand square leagues. We shall find it again in the vast plains of the Amazon, on the eastern boundary of the province of Jaen de Bracamoros. This prodigious extension of red sandstone in the low grounds stretching along the east of the Andes, is one of the most striking phenomena I observed during my examination of rocks in the equinoctial regions. The red sandstone of the Llanos of Caracas lies in a concave position, between the primitive mountains of the shore and of Parime. On the north it is backed by the * The Spanish colonists call the Crotophaga ani, zamurito (little car- rion vulture, — Vultur aura minuta), or garapatero, ' the eater of ^ara- p».as/ insects of the Acarus family. ROCKS OF T1IE PLAIKS. 136 transition-slates,* and on the south it rests immediately on the granites of the Orinoco. We observed in it rounded fragments of quartz (kieselschiefer), and Lydian stone, cemented by an olive-brown ferruginous clay. The cement is sometimes of so bright a red that the people of the country take it for cinnabar. We met a Capuchin monk at Calabozo, who was in vain attempting to extract mercury from this red sandstone. In the Mosa de Paja this rock con- tains strata of another quartzose sandstone, very fine-grained ; more to the south it contains masses of brown iron, and fragments of petrified trees of the monocotyledonous family, but we did not see in it any shells. The red sandstone, called by the Llaneros, the stone of the reefs (piedra de arrecifes), is everywhere covered with a stratum of clay. This clay, dried and hardened in the sun, splits into separate prismatic pieces with five or six sides. Does it belong to the trap-formation of Parapara ? It becomes thicker, and mixed with sand, as we approach the Bio Apure ; for near Calabozo it is one toise thick, near the mission of Gruayaval five toises, which may lead to the belief that the strata of red sandstone dips towards the south. We gathered in the Mesa de Pavones little nodules of blue iron-ore disseminated in the clay. A dense whitish-gray limestone, with a smooth fracture, somewhat analogous to that of Caripe, and consequently to that of Jura, lies on the red sandstone between Tisnao and Calabozo.f In several other places, for instance in the Mesa de San Diego, and between Ortiz and the Mesa de Paja,J we find above the limestone lamellar gypsum alter- nating with strata of marl. Considerable quantities of this gypsum are sent to the city of Caracas,§ which is situated amidst primitive mountains. This gypsum generally forms only small beds, and is mixed with a great deal of fibrous gypsum.

These questions are very interesting in the study of the relative antiquity of rocks, which is the principal basis of geology. I know not of any salt-deposits in the Llanos. Horned cattle prosper here without those famous bareros, or muriatiferous lands, which abound in the Pampas of Buenos Ayres.* After having wandered for a long time, and without any traces of a road, in the desert savannahs of the Mesa de Pavones, we were agreeably surprised when we came to a solitary farm, the Hato de Alfa Gracia, surrounded with gardens and basins of limpid water. Hedges of bead-trees encircled groups of icacoes laden with fruit. Farther on we passed the night near the small village of San Geronymo del Guayaval, founded by Capuchin missionaries. It is situated near the banks of the Rio Guarico, which falls into the Apure. I visited the missionary, who had no other habitation than his church, not haying yet built a house. He was a young man, and he received us in the most obliging manner, giving us all the information we desired. His village, or to use the word established among the monks, his Mission, was not easy to govern. The founder, who had not hesitated to establish for his own profit a pulperia, in other words, to sell bananas and guarapo in the church itself, had shown himself to be not very nice in the choice of the new colonists. Many marauders of the Llanoa had settled at Ghiayaval, because the inhabitants of a Mis- sion are exempt from the authority of secular law. Here, aa in Australia, it cannot be expected that good colonists \\ ill be formed before the second or third generation. "We passsd the Guarico, and encamped in the savannahs south of G-uayaval.

Tu the season of rains, a boat may be navigated, as on a lake, between the Guarico and the Apure. "We arrived on the 27th of March at the Villa de San Fer- nando, the capital of the Mission of the Capuchins in the province of Varinas. This was the termination of our journey over the Llanos ; for we passed the three months of April, May, and June on the rivers. CHAPTER XVIII. San Fernando de Apure. — Intertwinings and Bifurcations of the Rivera Apure and Arauca. — Navigation on the Rio Apure. TILL the second half of the eighteenth century the names of the great rivers Apure, Arauca, and Meta were scarcely known in Europe : certainly less than they had been in the two preceding centuries, when the valiant Felipe de Urre and the conquerors of Tocuyo traversed the Llanos, to seek, beyond the Apure, the great legendary city of El Dorado, an'd the rich country of the Omeguas, the Timbuctoo of the New Continent. Such daring expeditions could not be car- ried out without all the apparatus of war ; and the weapons, which had been destined for the defence of the new colo- nists, were employed without intermission against the unhappy natives. When more peaceful times succeeded to those of violence and public calamity, two powerful Indian tribes, the Cabres and the Caribs of the Orinoco, made themselves masters of the country which the Con- quistadores had ceased to ravage. None but poor monks were then permitted to advance to the south of the steppes. Beyond the TJritucu an unknown world opened to the Spanish colonists; and the descendants of those intrepid warriors who had extended their conquests from Peru to the coasts of New Grenada and the mouth of the Amazon, knew not the roads that lead from Coro to the Rio Meta. The shore of Venezuela remained a separate country ; and the slow conquests of the Jesuit missionaries were success- ful only by skirting the banks of the Orinoco. These 138 SITUATION OF THE TOWS. fathers had already penetrated beyond the great cataracts of Atures and Maypures, when the Andalusian Capuchins had scarcely reached the plains of Calabozo, from the coast and the valleys of Aragua. It would be difficult to explain these contrasts by the system according to which, the different monastic orders are governed ; for the aspect of the country contributes powerfully to the more or less rapid progress of the Missions. They extend but slowly into the interior of the land, over mountains, or in steppes, wherever they do not follow the course of a particular river. It will scarcely be believed, that the Villa de Fernando de Apure, only fifty leagues distant in a direct line from that part of the coast of Caracas which has been longest inhabited, was founded at no earlier a date than 1789. "We were shown a parch- ment, full of fine paintings, containing the privileges of this little town. The parchment was sent from Madrid at the solicitation of the monks, whilst yet only a few huts of reeds were to be seen around a great cross raised in the centre of the hamlet. The missionaries and the secular governments being alike interested in exaggerating in Europe what they have done to augment the culture and population of the provinces beyond sea, it often happens that names of towns and villages are placed on the list of new conquests, long before their foundation. The situation of San Fernando, on a large navigable river, near the mouth of another river which traverses the whole province of Varinas, is extremely advantageous for trade. Every production of that province, hides, cacao, cotton, and the indigo of Mijagual, which is of the first quality, passes through this town towards the mouths of the Orinoco. During the season of rains large vessels go from Angostura as far as San Fernando de Apure, and by the Bio Santo Domingo as far as Torufios, the port of the town of Varinas. At that period the inundations of the rivers, which form a labyrinth of branches between the Apure, the Arauca, the Capanaparo, and the Sinaruco, cover a country of nearly four hundred square leagues. At this point, the Orinoco, turned aside from its course, not by neighbouring moun- tains, but by the rising of counterslopes, runs eastward instead of following its previous direction in the line of the meridian. Considering the surface of the globe as a TLOODS IN T1IE SAVANNAHS. 132 poly hedron, formed of planes variously inclined, we may conceive by the mere inspection of the maps, that the inter- section of these slopes, rising towards the north, the west, and south,* between San Fernando de Apure, Caycara, and the mouth of the Meta, must cause a considerable depres- sion. The savannahs in this basin are covered with twelve or fourteen feet of water, and present, at the period of rains, the aspect of a great lake. The farms and villages which seem as if situated on shoals, scarcely rise two or three feet above the surface of the water. Everything here calls to mind the inundations of Lower Egypt, and the lake of Xarayes, heretofore so celebrated among geogra- phers, though it exists only during some months of the year. The swellings of the rivers Apure, Meta, and Orinoco, are also periodical. In the rainy season, the horses that wander in the savannah, and have not time to reach the rising grounds of the Llanos, perish by hundreds. The mares are seen, followed by their colts,t swimming during a part of the day to feed upon the grass, the tops of which alone wave above the waters. In this state they are pursued by the crocodiles, and it is by no means uncommon to find the prints of the teeth of these carnivorous reptiles on their thighs. The carcases of horses, mules, and cows, attract an innumerable quantity of vultures. The zamuros are the ibisis of this country, and they render the same service to the inhabitants of the Llanos as the Vultur percnopterus to the inhabitants of Egypt. We cannot reflect on the effects of these inundations without admiring the prodigious pliability of the organiza- tion of the animals which man has subjected to his sway. In Greenland the dog eats the refuse of the fisheries ; and when fish are wanting, feeds on seaweed. The ass and the * The risings towards the north and west are connected with two lines of ridgea, the mountains of Villa de Cura and of Merida.

Pressed alternately by excess of drought and of humidity, they sometimes seek a pool in the midst of a bare and dusty plain, to quench their thirst ; and at other times flee from water, and the over- flowing rivers, as menaced by an enemy that threatens them on all sides. Tormented during the day by gadflies and mosquitos, the horses, mules, and cows find themselves attacked at night by enormous bats, which fasten on their backs, and cause wounds that become dangerous, because fchey are filled with aearidae and other hurtful insects. In the time of great drought the mules gnaw even the thorny cactus* in order to imbibe its cooling juice, and draw it forth as from a vegetable fountain. During the great inunda- tions these same animals lead an amphibious life, surrounded by crocodiles, water-serpents, and manatis. Yet, such are the immutable laws of nature, that their races are preserved in the struggle with the elements, and amid so many suffer- ings and dangers. When the waters retire, and the rivers return again into their beds, the savannah is overspread with a beautiful scented grass ; and the animals of Europe and Upper Asia seem to enjoy, as in their native climes, the renewed vegetation of spring. During the time of great floods, the inhabitants of these countries, to avoid the force of the currents, and the danger arising from the trunks of trees which these currents bring down, instead of ascending the beds of rivers in their boats, cross the savannahs. To go from San Fernando to the villages of San Juan de Payara, San Raphael de Atamaica, or San Francisco de Capanaparo, they direct their course due south, as if they were crossing a single river of twenty leagues broad. The junctions of the Gruarico, the Apure, the Cabullare, and the Arauca with the Orinoco, form, at a hundred and sixty leagues from the coast of G-uiana, a kind of interior Delta, of which hydrography furnishes few ex- amples in the Old Woild.

The fall from the mouths of the Osage and the Missouri to the bar of the Mississippi is not more con- siderable. The savannahs of Lower Louisiana everywhere remind us of the savannahs of the Lower Orinoco. During our stay of three days in the little town of San Pernando, we lodged with the Capuchin missionary, who lived much at his ease. We were recommended to him by the bishop of Caracas, and he showed us the most obliging attention. He consulted me on the works that had been undertaken to prevent the flood from undermining the shore on which the town was built. The flowing of the Portuguesa into the Apure gives the latter an impulse towards south- east ; and, instead of procuring a freer course for the river^ attempts were made to confine it bv dykes and piers. It was easy to predict that these would be rapidly destroyed by the sweD of the waters, the shore having been weakened by taking away the earth from behind the dyke to employ it in these hydraulic constructions. San Fernando is celebrated for the excessive heat which prevails there the greater part of the year; and before I begin the recital of our long navigation on the rivers, I shall relate some facts calculated to throw light on the meteorology of the tropics. We went, provided with ther- mometers, to the flat shores covered with white sand which border the river Apure. At two in the afternoon I found the sand, wherever it was exposed to the sun, at 52'5°. The instrument, raised eighteen inches above the sand, marked 42'8°, and at six feet high 38'7°. The temperature of the air under the shade of a ceiba was 36'2°. These observations were made during a dead calm. As soon as the wind began to blow, the temperature of the air rose 3° higher, yet we were not enveloped by a wind of sand, but the strata of air had been in contact with a soil more strongly heated, or through which whirlwinds of sand had passed. This western part of the Llanos is the hottest, because it receives air that has already crossed the rest of the barren steppe. The same difference has been observed between the eastern and western parts of the deserts of Africa, where the trade-winds blow. 112 RIVER PORPOISES. The heat augments sensibly in the Llanos during the rainy season, particularly in the month of July, when the sky is cloudy, and reflects the radiant heat toward the earth. During this season the breeze entirely ceases ; and, accord- ing to good thermometrical observations made by M. Pozo, the thermometer rises in the shade to 39° and 39 '5°, though kept at the distance of more than fifteen feet from the ground. As we approached the banks of the Portuguesa, the Apure, and the Apurito, the air became cooler from the evaporation of so considerable a mass of water. This effect is more especially perceptible at sunset. During the day the shores of the rivers, covered with white sand, reflect the heat in an insupportable degree, even more than the yellowish brown clayey grounds of Calabozo and Tisnao. On the 28th of March I was on the shore at sunrise to measure the breadth of the Apure, which is two hundred and six toises. The thunder rolled in all directions around. It was the first storm and the first rain of the season. The river was swelled by the easterly wind ; but it soon became calm, and then some great cetacea, much resembling the porpoises of our seas, began to play in long files on the surface of the water. The slow and indolent crocodiles seem to dread the neighbourhood of these animals, so noisy and impetuous in their evolutions, for we saw them dive whenever they approached. It is a very extraordinary phe- nomenon to find cetacea at such a distance from the coast. The Spaniards of the Missions designate them, as they do the porpoises of the ocean, by the name of toninas. The Tamanacs call them orinucna. They are three or four feet ,ong; and bending their back, and pressing with their tail on the inferior strata of the water, they expose to view a part of the back and of the dorsal fin. I did not succeed in obtaining any, though I often engaged Indians to shoot at them with their arrows. Father Gili asserts that the Gumanos eat their flesh. Are these cetacea peculiar to the great rivers of South America, like the manati, which, according to Cuvier, is also a fresh water cetaceous animal ? or must we admit that they go up from the sea against the current, as the beluga sometimes does in the rivers of Asia ? What would lead me to doubt this last supposition is, that we saw toninas above the great cataracts ATMOSPHERIC ELECTRICITY. 113 of the Orinoco, in the Kio Atabapo* Did they penetrate into the centre of equinoctial America from the mouth of the Amazon, by the communication of that river with the Rio Negro, the Cassiquiare, and the Orinoco ? They are found here at all seasons, and nothing seems to denote that they make periodical migrations like salmon. While the thunder rolled around us, the sky displayed only scattered clouds, that advanced slowly toward the zenith, and in an opposite direction. The hygrometer of Deluc was at 53°, tne centigrade thermometer 23'7°, and Saussure's hygrometer 87*5°. The electrometer gave no sign of electricity. As the storm gathered, the blue of the sky changed at first to deep azure and then to grey. The vesicular vapour became visible, and the thermometer rose three degrees, as is almost always the case, within the tropics, from a cloudy sky which reflects the radiant heat of the soil. A heavy rain fell. Being sufficiently habituated to the climate not to fear the effect of tropical rains, we remained on the shore to observe the electrometer. I held it more than twenty minutes in my hand, six feet above the ground, and observed that in general the pith-balls separated only a few seconds before the lightning was seen. The separation was four lines. The electric charge remained the same during several minutes ; and having time to deter- mine the nature of the electricity, by approaching a stick of sealing-wax, I saw here what I had often observed on the ridge of the Andes during a storm, that the electricity of the atmosphere was first positive, then nil, and then ne- gative. These oscillations from positive to negative were often repeated. Tet the electrometer constantly denoted, a little before the lightning, only E., or + E., and never — E. Towards the end of the storm the west wind blew very strongly. The clouds dispersed, and the thermometer sunk to 22° on account of the evaporation from the soil, and the freer radiation towards the sky. I have entered into these details on the electric charge of the atmosphere because travellers in general confine themselves to the description of the impressions produced on a European newly arrived by the solemn spectacle of a tropical storm. In a country where the year is diyidod into 144 ELECTRIC PHENOMENA. great seasons of drought and wot, or, as the Indians eay in their expressive language, of sun* and rain,f it is highly interesting to follow the progress of meteorological pheno- mena in the transition from one season to another We had already observed, in the valleys of Aragua, from the 18th and 19th of February, clouds forming at the com- mencement of the night. In the beginning of the month of March the accumulation of the vesicular vapours, visible to the eye, and with them signs of atmospheric electricity, augmented daily. We saw flashes of heat-lightning to the south ; and the electrometer of Yolta constantly displayed, at sunset, positive electricity. The pith balls, unexcited during the day, separated to the width of three or four lines at the commencement of the night, which is triple what I generally observed in Europe, with the same instrument, in calm weather. Upon the whole, from the 26th of May, the electrical equilibrium of the atmosphere seemed disturbed. During whole hours the electricity was nil, then it became very strong, and soon after was again imperceptible. The hygrometer of Deluc continued to indicate great dryness (from 33° to 35°), and yet the atmosphere appeared no longer the same. Amidst these perpetual variations of the electric state of the air, the trees, divested of their foliage, already began to unfold new leaves, and seemed to feel the approach of spring. The variations which we have just described are not peculiar to one year. Everything in the equinoctial zone has a wonderful uniformity of succession, because the active powers of nature limit and balance each other, according to laws that are easily recognized. I shall here note the progress of atmospherical phenomena in the islands to the east of the Cordilleras of Merida and of New Grenada, in the Llanos of Venezuela and the Bio Meta, from four to ten degrees of north latitude, wherever the rains are constant * In the Maypure dialect camoti, properly "the heat [of the sun]."

APPROACH OF THE RAINY SEASO1C. 145 from May to October, and comprehending consequently the periods of the greatest heats, which occur in July and August.* Nothing can equal the clearness of the atmosphere from the month of December to that of February. The sky is then constantly without clouds; and if one should appear, it is a phenomenon that engages the whole attention ot the inhabitants. A breeze from the east, and from east-north- east, blows with violence. As it brings with it air always of the same temperature, the vapours cannot become visible by cooling. About the end of February and the beginning of Marcii, the blue of the sky is less intense, the hygrometer indicates by degrees greater humidity, the stars are sometimes veiled by a slight stratum of vapour, and their light is no longer steady and planetary ; they are seen twinkling from time to time when at 20° above the horizon. The breeze at this period becomes less strong, less regular, and is often inter- rupted by dead calms. The clouds accumulate towards south-south-east, appearing like distant mountains, with outlines strongly marked. From time to time they detach themselves from the horizon, and traverse the vault of the sky with a rapidity which little corresponds with the feeble wind prevailing in the lower strata of the air. At the end of March, the southern region of the atmosphere is illumined by small electric explosions. They are like phosphorescent gleams, circumscribed by vapour. The breeze then shifts from time to time, and for several hours together, to the west and south-west. This is a certain sign of the approach of the rainy season, which begins at the Orinoco about the end of April. The blue sky disappears, and a grey tint spreads uniformly over it. At the same time the heat of the atmosphere progressively increases; and soon the heavens are no longer obscured by clouds, but by condensed vapours. The plaintive cry of the howling apes begins to be heard before sunrise. The atmospheric electricity, which, during * The maximum of the heat is not felt on the coast, at Cumana, at La Guayra, and in the neighbouring island of Margareta, before the month of September; and the rains, if the name can be given to a few d'ops that fall at intervals, are observed only in the months of October and November. VOL. II. L 146 PBOPAGATION OF AEBIAL ACTION. the season of drought, from December to March, had been constantly, in the day-time, from 1-7 to 2 lines, becomes extremely variable from the month of March. It appears nil during whole days ; and then for some hours the pith- balls diverge three or four lines. The atmosphere, which is generally, in the torrid as well as in the temperate zone, in a state of positive electricity, passes alternately, for eight or ten minutes, to the negative state. The season of rains is that of storms; and yet a great number of experiments made during three years, prove to me that it is precisely in this season of storms we find the smallest degree of electric tension in the lower regions of the atmo- sphere. Are storms the effect of this unequal charge of the different superincumbent strata of air? "What pre- vents the electricity from descending towards the earth, in air which becomes more humid after the month of March ? The electricity at this period, instead of being diffused throughout the whole atmosphere, appears accumulated on the exterior envelope, at the surface of the clouds. Accor- ding to M. Gray-Lussac it is the formation of the cloud itself that carries the fluid toward its surface. The storm rises in the plains two hours after the sun has passed the meridian ; consequently a short time after the moment of the maxi- mum of diurnal heat within the tropics. It is extremely rare in the islands to hear thunder during the night, or in the morning. Storms at night are peculiar to certain valleys of rivers, having a pecul:ar climate. "What then are the causes of this rupture of the equili- brium in the electric tension of the air ? of this continual condensation of the vapours into water ? of this interruption of the breezes ? of this commencement and duration of the rainy seasons? I doubt whether electricity have any in- fluence on the formation of vapours. It is rather the for- mation of these vapours that augments and modifies the electrical tension. North and south of the equator, storms or great explosions take place at the same time in the temperate and in the equinoctial zone. Is there an action propagated through the great aerial ocean from the tem- perate zone towards the tropics 1 How can it be con- ceived, that in that zone where the sun rises constantly to so great a height above the horizon, its passage through ATMOSPHERIC CUBBLHTTB. 147 the zeiiith can have so powerful an influence on the meteo- rological variations ? 1 am of opinion that no local cause determines the commencement of the rains within the tro- pics ; and that a more intimate knowledge of the higher currents of air will elucidate these problems, so complicated in appearance. We can observe only what passes in the lower strata of the atmosphere. The Andes are scarcely inhabited beyond the height of two thousand toises ; and at that height the proximity of the soil, and the masses of moun tains, which form the shoals of the aerial ocean, have a sen- sible influence on the ambient air. What we observe on the table-land of Antisana is not what we should find at the same height in a balloon, hovering over the Llanos or the surface of the ocean. We have just seen that the season of rains and storms in the northern equinoctial zone coincides with the passage of the sun through the zenith of the place,* with the ces- sation of the north-east breezes, and with the frequency of calms and bendavales, which are stormy winds from south-east and south-west, accompanied by a cloudy sky. I believe that, in reflecting on the general laws of the equilibrium of the gaseous masses constituting our atmo- sphere, we may find, in the interruption of the current that blows from an homonymous pole, in the want of the renewal of air in the torrid zone, and in the continued action of an ascending humid current, a very simple cause of the coincidence of these phenomena, While the north-easterly breeze blows with all its violence north of the equator, it prevents the atmosphere which covers the equinoctial lands and seas from saturating itself with moisture. The hot and moist air of the torrid zone rises aloft, and flows off" again towards the poles; while inferior polar currents, bringing drier and colder strata, are every instant taking the place of the columns of ascending air. By this constant action of two opposite currents, the humidity, far from being accumu- lated in the equatorial region, is carried towards the cold and temperate regions. During this season of breezes, which is that when the sun is m the southern signs, the • These passages take place, in the fifth and tenth degrees of north lat. between the 3rd and the 16th of April, and between the 27th of August And the 8th of September. L 2 148 CHANGE OF THE SEASONS. »ky in the northern equinoctial zone is constantly serene, The vesicular vapours are not condensed, because the air, unceasingly renewed, is far from the point of saturation. In proportion as the sun, entering the northern signs, rises towards the zenith, the breeze from the north-east moderates, and by degrees entirely ceases. The diiference of tempera- ture between the tropics and the temperate northern zone is then the least possible. It is the summer of the boreal pole ; and, if the mean temperature of the winter, between 42° and 52° of north latitude, be from 20° to 26° of the centigrade thermometer less than the equatorial heat, the diiference in summer is scarcely from 4° to 6°. The sun being in the zenith, and the breeze having ceased, the causes which pro- duce humidity, and accumulate it in the northern equinoc- tial zone, become at once more active. The column of air reposing on this zone, is saturated with vapours, because it is no longer renewed by the polar current. Clouds form in this air saturated and cooled by the com- bined effects of radiation and the dilatation of the ascending air. This air augments its capacity for heat in proportion as it rarefies. With the formation and collection of the vesicular vapours, electricity accumulates in the higher re- gions of the atmosphere. The precipitation of the vapours is continual during the day ; but it generally ceases at night, and frequently even before sunset. The showers are regu- larly more violent, and accompanied with electric explosions, a short time after the maximum of the diurnal heat. This state of things remains unchanged, till the sun enters into the southern signs. This is the commencement of cold in the northern temperate zone. The current from the north-pole is then re-established, because the difference between the heat of the equinoctial and temperate regions augments daily. The north-east breeze blows with violence, the air of the tropics is renewed, and can no longer attain the degree of saturation. The rains consequently cease, the vesicular ?apour is dissolved, and the sky resumes its clearness and its azure tint. Electrical explosions are no longer heard, doubtless because electricity no longer comes in contact with the groups of vesicular vapours in the high regions of the air, I had almost said the coating of clouds, on which the fluid can accumulate. EQUATORIAL BAINS. 149 We have nere considered the cessation of the breezes as khe principal cause of the equatorial rains. These rains in each hemisphere last only as long as the sun has its decli- nation in that hemisphere. It is necessary to observe, that the absence of the breeze is not always succeeded by a dead calm ; but that the calm is often interrupted, particularly along the western coast of America, by bendavalrs, or south- west and south-east winds. This phenomenon seems to demonstrate that the columns of humid air which rise in the northern equatorial zone, sometimes flow off toward the south pole. In fact, the countries situated in the torrid zone, both north and south of the equator, furnish, during their summer, while the sun is passing through their zenith, the maximum of difference of temperature with the air of the opposite pole. The southern temperate zone has its winter, while it rains on the north of the equator; and while a mean heat prevails from 5° to 6° greater than in the time of drought, when the sun is lower.* The continuation of the rains, while the bendavales blow, proves that the currents from the remoter pole do not act in the northern equi- noctial zone like the currents of the nearer pole, on account of the greater humidity of the southern polar current. The air, wafted by this current, comes from a hemisphere consist- ing almost entirely of water. It traverses all the southern equatorial zone to reach the parallel of 8° north latitude ; and is consequently less dry, less cold, less adapted to act as a counter-current to renew the equinoctial air and prevent its saturation, than the northern polar current, or the breeze from the north-east.f We may suppose that the bendavales are impetuous winds which, on some coasts, for instance on that ol Gruatimala, (because they are not the effect of a regular and progressive descent of the air of the tropics towards the south pole, but they alternate with calms), are accompanied by electrical explosions, and are in fact squalls, * From the equator to 10* of north lat. the mean temperatures of the summer and winter months scarcely differ 2° or 3° ; but at the limits of the torrid zone, toward the tropic of Cancer, the difference amounts to 8° or 9°. t In the two temperate zones the air loses its transparency every time that the wind blows from the opposite pole, that is to say, from the pole that has not the same denomination as the hemisphere in which the wind blows. 150 PREPARATIONS FOE OUR YOYAGE. that indicate a reflux, an abrupt and instantaneous rapture, of equilibrium in the aerial ocean. We have here discussed one of the most important phe- nomena of the meteorology of the tropics, considered in its most general view. In the same manner as the limits of the trade-winds do not form circles parallel with the equator, the action of the polar currents is variously felt in different meridians. The chains of mountains and the coasts in the same hemisphere have often opposite seasons. There are several examples of these anomalies ; but, in order to dis- cover the laws of nature, we must know, before we examine into the causes of local perturbations, the average state of the atmosphere, and the constant type of its variations. The aspect of the sky, the progress of the electricity, and the shower of the 28th of March, announced the commence- ment of the rainy season ; we were still advised, however, to go from San Fernando de Apure by San Francisco de Capa- naparo, the Rio Sinaruco, and the Hato de San Antonio, to the village of the Ottomacs, recently founded near the banks of the Meta, and to embark on the Orinoco a little above Carichana. This way by land lies across an unhealthy and feverish country. An old farmer named Francisco San- chez obligingly offered to conduct us. His dress denoted the great simplicity of manners prevailing in those distant countries. He had acquired a fortune of more than 100,000 piastres, and yet he mounted on horseback with his feet bare, and wearing large silver spurs. We knew by the experience of several weeks the dull uniformity of the vegetation of the Llanos, and preferred the longer road, which leads by the Rio Apure to the Orinoco. We chose one of those very large canoes called lanchas by the Spaniards. A pilot and four Indians were sufficient to manage it. They constructed, near the stern, in the space of a few hours, a cabin covered with palm-leaves, sufficiently spacious to contain a table and benches. These were made of ox-hides, strained tight, and nailed to frames of brazil-wood. I mention these mi- nute circumstances, to prove that our accommodations on the Eio Apure were far different from those to which we were afterwards reduced in the narrow boats of the Orinoco. We loaded the canoe with provision for a month. Fowls, frggs, plantains, cassava, and cacao, are found in abundance DEPARTURE FROM SAN FERNA1TDO. 151 at San Fernando. The good Capuchin, Fray Jose Mafia de Malaga, gave us sherry wine, oranges, and tamarinds, tc make cooling beverages. We could easily foresee that a roof constructed of palm-tree leaves would become exces- sively hot on a large river, where we were almost always exposed to the perpendicular rays of the sun. The Indians relied less on the provision we had purchased, than on their hooks and nets. We took also some fire-arms, which we found in general use as far as the cataracts; but farther south the great humidity of the air prevents the mission- aries from using them. The Rio Apure abounds in fish, manatis, and turtles, the eggs of which afford an aliment more nutritious than agreeable to the taste. Its banks are inhabited by an innumerable quantity of birds, among which the pauxi and the guacharaca, which may be called the tur- keys and pheasants of those countries, are found to be the most useml. Their flesh appeared to be harder and less white than that of the gallinaceous tribe in Europe, because they use much more muscular exercise. We did not forget to add to our provision, fishing-tackle, fire-arms, and a few casks of brandy, to serve as a medium of barter with the Indians of the Orinoco. We departed from San Fernando on the 30th of March, at four in the afternoon. The weather was extremely hot ; the thermometer rising in the shade to 34°, though the breeze blew very strongly from the south-east. Owing to this contrary wind we could not set our sails. We were accompanied, in the whole of this voyage on the A pure, the Orinoco, and the Rio Negro, by the brother-in-law of the governor of the province of Varinas, Don Nicolas Soto, who had recently arrived from Cadiz. Desirous of visiting countries so calculated to excite the curiosity of a Euro- pean, .he did not hesitate to confine himself with us during seventy-four days in a narrow boat infested with mosquitos. His amiable disposition and gay temper often helped to make us forget the sufferings of a voyage which was not wholly exempt from danger. We passed the mouth of the Apurito, and coasted the island of the same name, formed by the Apure and the Gruarico. This island is in fact only a very low spot of ground, bordered by two great rivers, both of which, at a little distance from each other, fall uito 152 TAHURO INDIANS. the Orinoco, after having formed a junction below San Fer- nando by the first bifurcation of the Apure. The Isla del Apurito is twenty-two leagues in length, and two or three leagues in breadth. It is divided by the Cano de la Tigrera and the Cano del Manati into three parts, the two extremes of which bear the names of Isla de Blanco and Isla de los (xarzitas. The right bank of the Apure, below the Apurito, is somewhat better cultivated than the left bank, where the Yaruros, or Japuin Indians, have constructed a few huts with reeds and stalks of palm-leaves. These people, who live by hunting and fishing, are very skilful in killing jaguars. It is they who principally carry the skins, known in Europe by the name of tiger-skins, to the Spanish vil- lages. Some of these Indians have been baptized, but they never visit the Christian churches. They are considered as savages because they choose to remain independent. Other tribes of Yaruros live under the rule of the missionaries, in the village of Achaguas, situated south of the Bio Payara. The individuals of this nation, whom I had an opportunity of seeing at the Orinoco, have a stern expression of counte- nance ; and some features in their physiognomy, erroneously called Tartarian, belong to branches of the Mongol race, the eye very long, the cheekbones high, but the nose pro- minent throughout its whole length. They are taller, browner, and less thick-set than the Chayma Indians. The missionaries praise the intellectual character of the Yaruros, who were formerly a powerful and numerous nation en the banks of the Orinoco, especially in the environs of Cuycara, below the mouth of the G-uarico. We passed the night at Diamante, a small sugar-plantation formed opposite the island of the same name. During the whole of my voyage from San Fernando to San Carlos del Bio Negro, and thence to the town of Angostura, I noted down day by day, either in the boat or where we disembarked at night, all that appeared to me worthy of observation. Violent rains, and the prodigious quantity of mosquitos with which the air is filled on the banks of the Orinoco and the Cassiquiare, necessarily occa- sioned some interruptions ; but I supplied the omission by notes taken a few days after. I here subjoin some extracts from my journal. Whatever is written while the objects we BIVEE SCENERY. 153 describe are before our eyes bears a character of truth and individuality which gives attraction to things the least important. On the 31st March a contrary wind obliged us to remain on shore till noon. "We saw a part of some cane-fields laid waste by the effect of a conflagration which had spread from a neighbouring forest. The wandering Indians everywhere set fire to the forest where they have encamped at night ; and during the season of drought, vast provinces would be the prey of these conflagrations if the extreme hardness of the wood did not prevent the trees from being entirely consumed. We found trunks of desmanthus and mahogany which were scarcely charred two inches deep. Having passed the Diamante we entered a land inhabited only by tigers, crocodiles, and chiguires; the latter are a large species of the genus Cavia of Linnasus. We saw flocks of birds, crowded so closely together as to appear against the sky like a dark cloud which every instant changed its form. The river widens by degrees. One of its banks is generally barren and sandy from the effect of inundations ; the other is higher, and covered with lofty trees. In some parts the river is bordered by forests on each side, and forms a straight canal a hundred and fifty toises broad. The manner in which the trees are disposed is very remarkable. We first find bushes of SCMSO* forming a kind of hedge four feet high, and appearing as if they had been clipped by the hand of man. A copse of cedar, brazilletto, and lignum-vit«, rises behind this hedge. Palm-trees are rare ; we saw only a few scattered trunks of the thorny piritu and corozo. The large quadrupeds of those regions, the jaguars, tapirs, and peccaries, have made openings in the hedge of sauso which we have just described. Through these the wild animals pass when they come to drink at the river. As they fear but little the approach of a boat, we had the pleasure of viewing them as they paced slowly along the shore till they disappeared in the forest, which they entered by one of the narrow passes left at intervals between the bushes. These scenes, which were often re- peated, had ever for me a peculiar attraction. The pleasure * Hermesia castaneifolia. This is a new genus, approaching tha •khornea of Swartz. 154 GEOUPS or CROCODILES. they excite is not owing solely to the interest which the naturalist takes in the objects of his study, it is connected with a feeling common to all men who have been brought up in the habits of civilization. You find yourself in a new world, in the midst of untamed and savage nature. Now the jaguar, — the beautiful panther of America, — appears upon the shore; and now the hocco,* with its black plumage and tufted head, moves slowly along the sausos. Animals of the most different classes succeed each other. " Esse como en el Paradiso" "It is just as it was in Paradise," said our pilot, an old Indian of the Missions. Everything, indeed, in these regions recalls to mind the state of the primitive world with its innocence and felicity. But in carefully observing the manners of animals among themselves, we see that they mutually avoid and fear each other. The golden age has ceased ; and in this Paradise of the American forests, as well as everywhere else, sad and long experience has taught all beings that benignity is seldom found in alliance with strength. When the shore is of considerable breadth, the hedge of sauso remains at a distance from the river. In the inter- mediate space we see crocodiles, sometimes to the number of eight or ten, stretched on the sand. Motionless, with their jaws wide open, they repose by each other, without displaying any of those marks of affection observed in other animals living in society. The troop separates as soon as they quit the shore. It is, however, probably composed of tne male only, and many females; for as M. Descourtils, who has so much studied the crocodiles of St. Domingo, observed to me, the males are rare, because they kill one another in fighting during the season of their loves. These monstrous creatures are so numerous, that throughout the whole course of the river we had almost at every instant five or six in view. Yet at this period the swelling of the Bio Apure was scarcely perceived ; and consequently hundreds of crocodiles were still buried in the mud of the savannahs. About four in the afternoon we stopped to measure a dead crocodile which had been cast ashore. It was only sixteen feet eight inches long ; some days after M. Bonpland found another, a male, twenty-two feet three inches long. In * Ceyx alector, the peacock-pheasant ; C. pauxi, the cashew-bird. THEIR FEROCITY. 135 every zone, in America as in Egypt, this animal attains the same size. The species so abundant in the Apure, the Orinoco,* and the Rio de la Magdalena, is not a cayman, but a real crocodile, analagous to that of the Nile, having feet dentated at the external edges. When it is recollected that the male enters the age of puberty only at ten years, and that its length is then eight feet, we may presume that the crocodile measured by M. Bonpland was at least twenty- eight years old. The Indians told us, that at San Fernando scarcely a year passes, without two or three grown-up persons, particularly women who fetch water from the river, oeing drowned by these carnivorous reptiles. They related to us the history of a young girl of Uritucu, who by singular intrepidity and presence of mind, saved herself from the jaws of a crocodile. When she felt herself seized, she sought the eyes of the animal, and plunged her fingers into them with such violence, that the pain forced the crocodile to let her go, after having bitten off the lower part of her left arm. The girl, notwithstanding the enormous quantity of blood she lost, reached the shore, swimming with the hand that still remained to her. In those desert countries, where man is ever wrestling with nature, discourse daily turns on the best means that may be employed to escape from a tiger, a boa, or a crocodile ; every one prepares himself in some sort for the dangers that may await him. "I knew," said the girl of Uritucu coolly, "that the cayman lets go his hold, you push your fingers into his eyes." Long after my return to Europe, I learned that in the interior of Africa the negroes know and practise the same means of defence. Who does not recollect, with lively interest, Isaac, the guide of the unfortunate Mungo Park, who was seized twice by a crocodile, and twice escaped from the jaws of the monster, having succeeded in thrusting his fingers into the creature's eyes while under water. The African Isaac, and the young American girl, owed their safety to the same presence of mind, and the same combination of ideas. The movements of the crocodile of the Apure are sudden and rapid when it attacks any object ; but it moves with the slowness of a salamander, when not excited by rage * It is the arva of the Tamanac Indians, the amana of the Maypurf Indians, the Crocudilus acutus of Cuvier. young , if 150 HABITS OF THE CAYMAJf. or hunger. The animal hi running makes a rustling noise, which seems to proceed from the rubbing of the scales of its skin one against another. In this movement it bends its back, and appears higher on its legs than when at rest. "We often heard this rattling of the scales very near us on the shore ; but it is not true, as the Indians pretend, that, like the armadillo, the old crocodiles "can erect their scales, and every part of their armour." The motion of these animals is no doubt generally in a straight line, or rather like that of an arrow, supposing it to change its direction at certain distances. However, notwithstanding the little apparatus of false ribs, which connects the vertebra of the neck, and seems to impede the lateral movement, crocodiles can turn easily when they please. I often saw young ones biting their tails ; and other observers have seen the same action in crocodiles at their full growth. If their movements almost always appear to be straight forward, it is because, like our small lizards, they move by starts. Crocodiles are excellent swimmers; they go with facility against the most rapid current. It appeared to me, however, that in descending the river, they had some difficulty in turning quickly about. A large dog, which had accompanied us in our journey from Caracas to the Bio JSTegro, was one day pursued in swimming by an enormous crocodile. The latter had nearly reached its prey, when the dog escaped by turn- ing round suddenly and swimming against the current. The crocodile performed the same movement, but much more slowly than the dog, which succeeded in gaining the shore. The crocodiles of the Apure find abundant food in the chiguires (thick-nosed tapirs),* which live fifty or sixty together in troops on the banks of the river. These animals, as large as our pigs, have no weapons of defence ; they swim somewhat better than they run : yet they become the prey * Cavia capybara, Linn. The word chigmre belongs to the language of the Palenkas and the Cumanagotos. The Spaniards call this animal guardatinaja ; the Caribs, capigua; the Tamanacs, cappiva; and the Maypures, chiato. According to Azara, it is known at Buenos Ayres by the Indian names of capiyyua and capiguara. These various denomi- nations show a striking analogy between the languages of the Orinoco and those of the Rio de la Plata. CAWO DE LA TIGRERA. 157 of the crocodiles in the water, and of the tigers on land. It is difficult to conceive, how, being thus persecuted by two powerful enemies, they become so numerous ; but they breed with the same rapidity as the little cames or guinea- pigs, which come to us from Brazil. We stopped below the mouth of the Cafio de la Tigrera, in a sinuosity called la Vuelta del Joval, to measure the velocity of the water at its surface. It was not more than 3'2 feet* in a second, which gives 2'56 feet for the mean velo- city. The height of the barometer indicated barely a slope of seventeen inches in a mile of nine hundred and fifty toises. The velocity is the simultaneous effect of the slope of the ground, and the accumulation of the waters by the swelling of the upper parts of the river. We were again surrounded by chiguires, which swim like dogs, raising their heads and necks above the water. We saw with surprise a large crocodile on the opposite shore, motionless, and sleeping in the midst of these nibbling animals. It awoke at the ap- proach of our canoe, and went into the water slowly, without frightening the chiguires. Our Indians accounted for this indifference by the stupidity of the animals, but it is more probable that the chiguires know by long experience, that the crocodile of the Apure and the Orinoco does not attack upon land, unless he finds the object he would seize imme- diately in his way, at the instant when he throws himself into the water. Near the Joval nature assumes an awful and extremely wild aspect. We there saw the largest jaguar we had ever met with. The natives themselves were astonished at its pro- digious length, which surpassed that of any Bengal tiger I had ever seen in the museums of Europe. The animal lay stretched beneath the shade of a large zamang.* It had just killed a chiguire, but had not yet touched its prey, on which it kept one of its paws. The zamuro vultures were assembled in great numbers to devour the remains of the jaguar's repast. They presented the most curious spectacle, * In order to measure the velocity of the surface of a river, I generally measured on the beach a base of 250 feet, and observed with the chrono- meter the time that a floating body, abandoned to the current, required to reach this distance. t A species of mimosa. 158 EXOEMOUS JAGFAB. by a singular mixture of boldness and timidity. They ad» vanced within the distance of two feet from the animal, but at the least movement he made they drew back. In order to observe more nearly the manners of these creatures, we went into the little skiff that accompanied our canoe. Tigers very rarely attack boats by swimming to them ; and never but when their ferocity is heightened by a long privation of food. The noise of our oars led the animal to rise slowly, and hide itself behind the sauso bushes that bordered the shore. The vultures tried to profit by this moment of absence to devour the chiguire ; but the tiger, notwith- standing the proximity of our boat, leaped into the midst of them, and in a fit of rage, expressed by his gait and the movement of his tail, carried off his prey to the forest. The Indians regretted that they were not provided with their lances, in order to go on shore and attack the tiger. They are accustomed to this weapon, and were right in not trusting to our fire-arms. In so excessively damp an atmosphere muskets often miss fire. Continuing to descend the river, we met with the great herd of chiguires which the tiger had put to flight, and from which he had selected his prey. These animals saw us land very unconcernedly ; some of them were seated, and gazed upon us, moving the upper lip like rabbits. They seemed not to be afraid of man, but the sight of our dog put them to flight. Their hind legs being longer than their fore legs, their pace is a slight gallop, but with so little swiftness that we succeeded in catching two of them. The chiguire, which swims with the greatest agility, utters a short moan in running, as if its respiration were impeded. It is the largest of the family of rodentia or gnawing animals. It defends itself only at the last extremity, when it is surrounded and wounded. Having great strength in its grinding teeth,* particularly the hinder ones, which are pretty long, it can tear the paw of a tiger, or the leg of a horse, with its bite. * We counted eighteen on each side. On the hind feet, at the upper end of the metatarsus, there is a callosity three inches long and three quarters of an inch broad, destitute of hair. The animal, when seated, rests upon this part. No tail is visible externally ; but on putting aside the hair we discover a tubercle, a mass of naked and wrinkled flesh, of a conical figure, and half an inch long. A WHITE CABALLEBO. 159 Its flesh has a musky smell somewhat disagreeable; jet hams are made of it in this country, a circumstance which almost justifies the name of 'water-hog,' given to the chiguire by some of the older naturalists. The missionary monks do not hesitate to eat these hams during Lent. According to their zoological classification they place the armadillo, the thick-nosed taper, and the manati, near the tortoises; the first, because it is covered with a hard ar- mour like a sort of shell ; and the others because they are amphibious. The chiguires are found in such numbers on the banks of the rivers Santo Domingo, Apure, and Arauca, in the marshes and in the inundated savannahs* of the Llanos, that the pasturages suffer from them. They browze the grass which fattens the horses best, and which Dears the name of chiguirero, or chiguire-grass. They feed also upon fish ; and we saw with surprise, that, when scared by the approach of a boat, the animal in diving remains eight or ten minutes under water. We passed the night as usual, in the open air, though in a plantation, the proprietor of which employed himself in hunting tigers. He wore scarcely any clothing, and was of a dark brown complexion like a Zambo. This did not pre- vent his classing himself amongst the Whites. He called his wife and his daughter, who were as naked as himself, Dona Isabella and Dona Manuela. Without having ever quitted the banks of the Apure, he took a lively interest in the news of Madrid, — enquiring eagerly respecting " those never-ending wars, and everything down yonder (todas las cosas de alia)." He knew, he said, that the king was soon to come and visit " the grandees of the country of Caracas," but he added with some pleasantry, " as the people of the court can eat only wheaten bread, they will never pass beyond the town of Victoria, and we shall not see them here." I had brought with me a chiguire, which I had intended tc have roasted; but our host assured us, that such 'Indian game' was not food fit for "nos otros caballeros llancos" (white gentlemen like ourselves and him). Accordingly he offered us some venison, which he had killed the day before with an arrow, for he had neither powder nor fire-arms. • Near Uritucu, in the Caflo del Ravanal, we saw a flock of eighty o »ne hundred of these animals. 160 LUDICBOTJS "We supposed that a small wood of plantain-trees con« cealed from us the hut of the farm ; but this man, so proud of his nobility and the colour of his skin, had not taken the trouble of constructing even an ajoupa, or hut of palm- leaves. He invited us to have our hammocks hung near his own, between two trees ; and he assured us, with an air of complacency, that, if we came up the river in the rainy season, we should find him beneath a roof (baxo techo). We soon had reason to complain of a system of philosophy which is indulgent to indolence, and renders a man indifferent to the conveniences of life. A furious wind arose after midnight, lightnings flashed over the horizon, thunder rolled, and we were wet to the skin. During this storm a whimsical incident served to amuse us for a moment. Dona Isabella's cat had perched upon the tamarind-tree, at the foot of which we lay. It fell into the hammock of one of our companions, who, being hurt by the claws of the cat, and suddenly aroused from a profound sleep, imagined he was attacked by some wild beast of the forest. We ran to him on hearing his cries, and had some trouble to con- vince him of his error. While it rained in torrents on our hammocks and on our instruments which we had brought ashore, Don Ignacio congratulated us on our good fortune in not sleeping on the strand, but finding ourselves in his domain, among whites and persons of respectability (entre gente blanca y de trato) . Wet as we were, we could not easily persuade ourselves of the advantages of our situation, and we listened with some impatience to the long narrative our host gave us of his pretended expedition to the Rio Meta, of the valour he had displayed in a sanguinary com- bat with the Gruahibo Indians, and "the services that he had rendered to God and his king, in carrying away Indian children (los Indiecitos) from their parents, to distribute them in the Missions." We were struck with the singu- larity of finding in that vast solitude a man believing him- self to be of European race and knowing no other shelter than the shade of a tree, and yet having all the vain pre- tensions, hereditary prejudices, and errors of long-standing civilization ! On the 1st of April, at sunrise, we quitted Sefior Don Ignacio and Senora Dona Isabella his wife. The weather THE GUAMO INDIANS 101 was cooler, for the thermometer (which generally kept up in the daytime to 30° or 35°) had sunk to 24°. The tempera- ture of the river was little changed : it continued constantly at 26° or 27°. The current carried with it an enormous number of trunks of trees. It might be imagined that on ground entirely smooth, and where the eye cannot dis- tinguish the least hill, the river would have formed by the force of its current a channel in a straight line; but a glance at the map, which I traced by the compass, will prove the contrary. The two banks, worn by the waters, do not furnish an equal resistance; and almost impercep- tible inequalities of the level suffice to produce great sinuo- sities. Yet below the Joval, where the bed of the river enlarges a little, it forms a channel that appears perfectly straight, and is shaded on each side by very tall trees. This part of the river is called Cano Rico. I found it to be one hundred and thirty-six toises broad. We passed a low island, inhabited by thousands of flamingos, rose- coloured spoonbills, herons* and moorhens, which displayed plumage of the most various colours. These birds were BO close together that they seemed to be unable to stir. The island they frequent is called Isla de Aves, or Bird Island. Lower down we passed the point where the Bio Arichuna, an arm of the Apure, branches off to the Cabu- lare, carrying away a considerable body of its waters. We stopped, on the right bank, at a little Indian mission, inha- bited by the tribe of the Guamos, called the village of Santa Barbara de Arichuna. The Guamos* are a race of Indians very difficult to fix on a settled spot. They have great similarity of manners with the Achaguas, the Guajibos,f and the Ottomacs, par- taking their disregard of cleanliness, their spirit of ven- geance, and their taste for wandering ; but their language differs essentially. The greater part of these four tribes live by fishing and hunting, in plains often inundated, situated between the Apure, the Meta, and the Guaviare. The nature of these regions seems to invite the natives to a wandering life. On entering the mountains of the Cata- • Father Gili observes that their Indian name is Uamtt and Pau, aad that they originally dwelt on the Upper Apure. f Their Indian name is Guahiva. TOL. II. M 162 THE WOODS AT NIGHT. facts of the Orinoco, we shall soon find, among the Piraoas, the Macos, and the Maquiritaras, milder manners, a love of agriculture, and great cleanliness in the interior of their huts. On mountain ridges, in the midst of impenetrable forests, man is compelled to fix himself, and cultivate a small spot of land. This cultivation requires little care; while, in a country where there are no other roads than rivers, the life of the hunter is laborious and difficult. The Q-uamos of the mission of Santa Barbara could not furnish us with the provision we wanted. They cultivate only a little cassava. They appeared hospitable; and when we entered their huts, they offered us dried fish, and water cooled in porous vessels. Beyond the Vuelta del Cochino Roto, in a spot where the river has scooped itself a new bed, we passed the night on a bare and very extensive strand. The forest being impenetrable, we had the greatest difficulty to find dry wood to light fires, near which the Indians believe them- selves in safety from the nocturnal attacks of the tiger. Our own experience seems to bear testimony in favour of this opinion; but Azara asserts that, in his time, a tiger in Paraguay carried off" a man who was seated near a fire lighted in the savannah. The night was calm and serene, and there was a beautiful moonlight. The crocodiles, stretched along the shore, placed themselves in such a manner as to be able to see the fire. We thought we observed that its blaze attracted them, as it attracts fishes, crayfish, and other inhabitants of the water. The Indians showed us the tracks of three tigers in the sand, two of which were very young. A female had no doubt conducted her little ones to drink at the river. Finding no tree on the strand, we stuck our oars in the, ground, and to these we fastened our hammocks. Every- thing passed tranquilly till eleven at night ; and then a noise so terrific arose in the neighbouring forest, that it was almost impossible to close our eyes. Amid the cries of so many wild beasts howling at once, the Indians discriminated such only as were at intervals heard separately. These were the little soft cries of the sapajous, the moans of the alouate apes, the bowlings of the jaguar and couguar, the peccary, and the sloth, and the cries of the curassao, the NOCIUBNAL DISTURBANCES. lt>3 parraka, and other gallinaceous birds. When the jaguaru approached the skirt of the forest, our dog, which till then had never ceased barking, began to howl and seek for shelter beneath our hammocks. Sometimes, after a long silence, the cry of the tiger came from the tops of the trees ; and then it was followed by the sharp and long whistling of the monkeys, which appeared to flee from the danger that threatened them. We heard the same noises repeated, during the course of whole months, whenever the forest approached the bed of the river. The security evinced by the Indians inspires confidence in the minds of travellers, who readily persuade themselves that the tigers are afraid of fire, and that they do not attack a man lying in his ham- mock. These attacks are in fact extremely rare; and, during a long abode in South America, I remember only one example, of a llanero, who was found mutilated in his hammock opposite the island of Achaguas. When the natives are interrogated on the causes of the tremendous noise made by the beasts of the forest at certain hours of the night, the answer is, " They are keeping the feast of the full moon." I believe this agitation is most frequently the effect of some conflict that has arisen in the depths of the forest. The jaguars, for instance, pursue the peccaries and the tapirs, which, having no defence but in their numbers, flee in close troops, and break down the bushes they find in their way. Terrified at this struggle, the timid and mistrustful monkies answer, from the tops of the trees, the cries of the large animals. They awaken the birds that live in society, and by degrees the whole assembly is in commotion. It is not always in a fine moonlight, but more particularly at the time of a storm and violent showers, that this tumult takes place among the wild beasts. " May Heaven grant them a quiet night and repose, and us also !" said the monk who accompanied us to the Rio Negro, when, sinking with fatigue, he assisted in arranging our accommodations for the night. It was indeed strange, to find no silence in the solitude of woods. In the inns of Spain we dread the scund of guitars from the next apartment ; on the Orinoco, where the traveller's resting-place is- the open beach, or beneath M 2 164 EIYEE-SCKNEBY. the shelter of a solitary tree, his slumbers are disturbed by a serenade from the forest. "We set sail before sunrise, on the 2nd of April. The morning was beautiful and cool, according to the feelings of those who are accustomed to the heat of these climates. The thermometer rose only to 28° in the air, but the dry and white sand of the beach, notwithstanding its radiation towards a cloudless sky, retained a temperature of 36°. The porpoises (toninas) ploughed the river in long files. The shore was covered with fishing-birds. Some of these perched on the floating wood as it passed down the river, and surprised the fish that preferred the middle of the stream. Our canoe was aground several times during the morning. These shocks are sufficiently violent to split a light bark. "We struck on the points of several large trees, which remain for years in an oblique position, sunk in the mud. These 1rees descend from Sarare, at the period of great inun- dations, and they so fill the bed of the river, that canoes in going up find it difficult sometimes to make their way over the shoals, or wherever there are eddies. We reached a spot near the island of Carizales, where we saw trunks of the locust-tree, of an enormous size, above the surface of the water. They were covered with a species of plotus, nearly resembling the anhinga, or white bellied darter. These birds perch in files, like pheasants and parrakas, and the^ remain for hours entirely motionless, with their beaks raised toward the sky. Below the island of Carizales we observed a diminution of the waters of the river, at which we were the more sur- prised, as, after the bifurcation at la Boca de Arichuna, there is no branch, no natural drain, which takes away water froi^ the Apure. The loss is solely the effect of evaporation, and of filtration on a sandy and wet shore. Some idea of the magnitude of these effects may be formed, from the fact that we found the heat of the dry sands, at different hours of the day, from 36° to 52°, and that of sands covered with three or four inches of water 32°. The beds of rivers are heated as far as the depth to which the solar rays can penetrate without undergoing too great an extinction in their passage through the si^erincumbent strata of water. GREAT EXTENT OF IVAPOBATiOW. 1G5 Besides, filtration extends in a lateral direction far beyond the bed of the river. The shore, which apears dry to us, imbibes water as far up as to the level of the surface of the river. "We saw water gush out at the distance of fifty toises from the shore, every time that the Indians struck their oars into the ground. Now these sands, wet below, but dry above, and exposed to the solar rays, act like sponges, and lose the infiltrated water every instant by evaporation. The vapour that is emitted, traverses the upper stratum of sand strongly heated, and becomes sensible to the eye when the air cools towards evening. As the beach dries, it draws from the river new portions of water ; and it may be easily conceived that this continual alternation of va- porization and lateral absorption must cause an immense loss, difficult to submit to exact calculation. The increase of these losses would be in proportion to the length of the course of the rivers, if from their source to their mouth they were equally surrounded by a flat shore ; but these shores being formed by deposits from the water, and the water having less velocity in proportion as it is more remote from its source, throwing down more sediment in the lower than in the upper part of its course, many rivers in hot climates undergo a diminution in the quantity of their water, as they approach their outlets. Mr. Barrow observed these curioua effects of sands in the southern part of Africa, on the banks of the Orange River. They have also become the subject of a very important discussion, in the various hypotheses that have been formed respecting the course of the Niger.* Near the Vuelta de Basilio, where we landed to collect plants, we saw on the top of a tree two beautiful little monkeys, black as jet, of the size of the sai, with prehensile tails. Their physiognomy and their movements sufficiently showed that they were neither the quato (Simia beelzebub) • Geographers supposed, to* a long period, that the Niger was entirely absorbed by the sands, and evaporated by the heat of the tropical sun, as no embouchure could be found on the western coast of Africa to meet the requirements of so enormous a river. It was discovered, however, by the Landers, in 1830, that it does really flow into the Atlantic; yet the cause mentioned above is so powerful, that of all the numerous branches into which it separates at its mouth, only one (the Nun River) is navigable even for light ships, and for half the year even those art unable to enter. 166 THE IGUAFA. nor the chcutnek^ nor any of the Ateles. Our Indians them- selves had never seen any that resembled them. Monkeys, especially those living in troops, make long emigrations at certain periods, and consequently it happens that at the beginning of the rainy seasons the natives discover round their huts different kinds which they have not before observed. On this same bank our guides showed us a nest of young iguanas only four inches long. It was difficult to distinguish them from common lizards. There was no distinguishing mark yet formed but the dewlap below the throat. The dorsal spines, the large erect scales, all those appendages that render the iguana so remarkable when it attains its full growth, were scarcely traceable. The flesh of this animal of the saurian family appeared to us to have an agreeable taste in every country where the climate is very dry ; we even found it so at periods when we were not in want of other food. It is extremely white, and next to the flesh of the armadillo, one of the best kinds of food to be found in the huts of the natives. It rained toward evening, and before the rain fell, swal- lows, exactly resembling our own, skimmed over the surface of the water. We saw also a flock of paroquets pursued by little goshawks without crests. The piercing cries of these paroquets contrasted singularly with the whistling of the birds of prey. We passed the night in the open air, upon the beach, near the island of Carizales. There were several Indian huts in the neighbourhood, surrounded with plan- tations. Our pilot assured us beforehand that we should not hear the cries of the jaguar, which, when not extremely pressed by hunger, withdraws from places where he does not reign unmolested. " Men put him out of humour" (los hombres lo enfadan), say the people in the Missions. A pleasant and simple expression, that marks a well-observed fact. Since our departure from San Fernando we had not met a single boat on this fine river. Everything denoted the most profound solitude. On the morning of the 3rd of April our Indians caught with a hook the fish known in the country by the name of caribe* or caribito, because no other fish has such a thirst for blood. It attacks bathers and * Caribe in the Spanish language signifies cannibal. THE CAKTBE FISH. 1G7 swimmers, from whom it often bites away considerable pieces of flesh. The Indians dread extremely these caribes ; and several of them showed us the scars of deep wounds in the calf of the leg and in the thigh, made by these little animals. They swim at the bottom of rivers ; but if a few drops of blood be shed on the water, they rise by thou- sands to the surface, so that if a person be only slightly bitten, it is difficult for him to get out of the water without receiving a severer wound. When we reflect on the numbers of these fish, the largest and most voracious of which are only four or five inches long, on the triangular form of their sharp and cutting teeth, and on the amplitude of their re- tractile mouths, we need not be surprised at the fear which the caribe excites in the inhabitants of the banks of the A pure and the Orinoco. In places where the river was very limpid, where not a fish appeared, we threw into the water little morsels of raw flesh, and in a few minutes a perfect cloud of caribes had come to dispute their prey. The belly of this fish has a cutting edge, indented like a saw, a characteristic which may be also traced in the serra-salmes, the myletes, and the pristigastres. The pre- sence of a second adipous dorsal fin, and the form of the teeth, covered by b'ps distant from each other, and largest in the lower jaw, place the caribe among the serra-salmes . Its mouth is much wider than that of the myletes of Cuvier. Its body, toward the back, is ash-coloured with a tint of green, but the belly, the gill-covers, and the pectoral, anal, and ventral fins, are of a fine orange hue. Three species are known in the Orinoco, and are distinguished by their size. The intermediate appears to be identical with the medium species of the piraya, or piranha, of Marcgrav.* The can- bito has a very agreeable flavour. As no one dares to bathe where it is found, it may be considered as one of the greatest scourges of those climates, in which the sting of the mosquitos and the general irritation of the skin render the use of baths so necessary. We stopped at noon in a desert spot called Algodonal. I left my companions while they drew the boat ashore and were occupied in preparing our dinner. I went along the beach to get a n?ar view of a group of crocodiles sleeping in * Salmo rhombeui, Linn. 168 ALARMING RENCONTRE. the sun, and lying in such a manner as to have their tails, which were furnished with broad plates, resting on one an- other. Some little herons,* white as snow, walked along their backs, and even upon their heads, as if passing over trunks of trees. The crocodiles were of a greenish grey, half covered with dried mud ; from their colour and immobility they might have been taken for statues of bronze. This ex- cursion had nearly proved fatal to me. I had kept my eyea constantly turned towards the river ; but, whilst picking up some spangles of mica agglomerated together in the sand, I discovered the recent footsteps of a tiger, easily distinguish- able from their form and size. The animal had gone towards the forest, and turning my eyes on that side, I found myself within eighty paces of a jaguar that was lying under the thick foliage of a ceiba. No tiger had ever appeared to me so large. There are accidents in life against which we may seek in vain to fortify our reason. I was extremely alarmed, yet sufficiently master of myself and of my motions to enable me to follow the advice which the Indians had so often given us as to how we ought to act in such cases. I con- tinued to walk on without running, avoided moving my arms, and I thought I observed that the jaguar's attention waa fixed on a herd of capybaras which was crossing the river. I then began to return, making a large circuit toward the edge of the water. As the distance increased, I thought I might accelerate my pace. How often was I tempted to look back in order to assure myself that I was not pursued ! Happily I yielded very tardily to this desire. The jaguar had re- mained motionless. These enormous cats with spotted robes are so well fed in countries abounding in capybaras, pecaries, and deer, that they rarely attack men. 1 arrived at the boat out of breath, and related my adventure to the Indians. They appeared very little interested by my story ; yet, after having loaded our guns, they accompanied us to the ceiba *r Garzon chico. It is believed, in Upper Egypt, that herons have an affection for crocodiles, because they take advantage in fishing of the terror that monstrous animal causes among the fishes, which he drives from the bottom to the surface of the water ; but on the banki of the Nile, the heron keeps prudently at some distance from the cro- codile. THE MANATI 169 beneath which the jaguar had lain. He was there no longer, and it would have been imprudent to have pursued him into the forest, where we must have dispersed, or advanced in single file, amidst the intertwining lianas. In the evening we passed the mouth of the Cafio del Manati, thus named on account of the immense quantity of manatis caught there every year. This herbivorous animal of the cetaceous family, is called by the Indians apcia and avia* and it attains here generally ten or twelve feet in length. It usuaDv weighs from five hundred to eight hun- dred pounds, but it is asserted that one has been taken of eight thousand pounds weight. The manati abounds in the Orinoco below the cataracts, in the Bio Meta, and in the A pure, between the two islands of Carizales and Coiiserva. "We found no vestiges of nails on the external surface or the edges of the fins, which are quite smooth ; but little rudiments of nails appear at the third phalanx, when the skin of the fins is taken off. "We dissected one of these animals, which was nine feet long, at Carichana, a Mission of the Orinoco. The upper lip was four inches longer than the lower one. It was covered with a very fine skin, and served as a proboscis. The inside of the mouth, which has a sensi- ble warmth in an animal newly killed, presented a very singular conformation. The tongue was almost motionless ; but in front of the tongue there was a fleshy excrescence in each jaw, and a cavity lined with a very hard skin, into which the excrescence fitted. The manati eats such quantities of grass, that we have found its stomach, which is divided into several cavities, and its intestines, (one hundred and eight feet long,) filled with it. On opening the animal at the back, we were struck with the magnitude, form, and situa- tion of its lungs. They have very large cells, and resemble immense swimming-bladders. They are three feet long. Filled with air, they have a bulk of more than a thousand cubic inches. I was surprised to see that, possessing such * The first of these words belongs to the Tamanac language, and the second to the Ottomae. Father Gili proves, in opposition to Oviedo, that the manati (fish with hands) is not Spanish, but belongs to the languages of Hayti (St. Domingo) and the Maypurec. I believe also that, according to the genius of the Spanish tongue, the anizva! would have been called manudo or manon, but not manati. 170 THE MAJTATT. considerable receptacles for air, the manati comos so cften to the surface of the water to breathe. Its flesh is very savoury, though, from what prejudice I know not, it is con- sidered unwholesome and apt to produce fever. It ap- peared to me to resemble pork rather than beef. It is most esteemed by the Gruamos and the Ottomacs ; and these two nations are particularly expert in catching the manati. Its flesh, when salted and dried in the sun, can be preserved a whole year; and, as the clergy regard this mammiferous animal as a fish, it is much sought during Lent. The vital principal is singularly strong in the manati ; it is tied after being harpooned, but is not killed till it has been taken into the canoe. This is effected, when the animal is very large, in the middle of the river, by filling the canoe two-thirds with water, sliding it under the animal, and then baling out the water by means of a calabash. This fishery is most easy after great inundations, when the manati has passed from the great rivers into the lakes and surrounding marshes, and the waters diminish rapidly. At the period when the Jesuits governed the Missions of the Lower Orinoco, they assembled every year at Cabruta, below the mouth of the Apure, to have a grand fishing for manatis, with the Indians of their Missions, at the foot of the moun- tain now called El Capuchino. The fat of the animal, known by the name of manati-butter (manteca de manati,) is used for lamps in the churches ; and is also employed in preparing food. It has not the fetid smell of whale-oil, or that of the other cetaceous animals which spout water. The hide of the manati, which is more than an inch and half thick, is cut into slips, and serves, like thongs of ox-leather, to supply the place of cordage in the Llanos. When im- mersed in water, it has the defect of undergoing a slight degree of putrefaction. "Whips are made of it in the Spa- nish colonies. Hence the words latigo and manati are synonymous. These whips of manati-leather are a cruel instrument of punishment for the unhappy slaves, and even for the Indians of the Missions, though, according to the laws, the latter ought to be treated like freemen. "We passed the night opposite the island of Conserva. In skirting the forest we were surprised by the sight of an enor- mous trunk of a tree seventy feet high, and thickly set witb THE TAMPIBE-BAT. 171 branching thorns. It is called hy the natives barba de twre. It was perhaps a tree of the berberideous family.* The Indians nad kindled fires at the edge of the water. We again perceived, that their light attracted the crococ'Jles, and even the porpoises (toninas), the noise of which inter- rupted our sleep, till the fire was extinguished. A female jaguar approached our station whilst taking her young one to drink at the river. The Indians succeeded in chasing her away, but we heard for a long time the cries of the little jaguar, which mewed like a young cat. Soon after, our great dog was bitten, or, as the Indians say, stung, at the point of the nose, by some enormous bats that hovered around our hammocks. These bats had long tails, like the Mo- losses : I believe, however, that they were Phyllostomes, the tongue of which, furnished with papillae, is an organ of suction, and is capable of being considerably elongated. The dog's wound was very small and round ; and though he uttered a plaintive cry when he felt himself bitten, it was not from pain, but because he was frightened at the sight of the bats, which came out from beneath our hammocks. These accidents are much more rare than is believed even in the country itself. In the course of several years, not- withstanding we slept so often in the open air, in climates where vampire-bats, t and other analagous species are so common, we were never wounded. Besides, the puncture is no-way dangerous, and in general causes so little pain, that it often does not awaken the person till after the bat has withdrawn. The 4th of April was the last day we passed on the Bio ^ipure. The vegetation of its banks became more and more uniform. During several days, and particularly since we had left the Mission of Arichuna,, we had suffered cruelly from the stings of insects, which covered our faces and hands. They were not mosquitos, which have the appear- * We found, on the banks of the Apure, Ammania apurensis, Cordia cordifolia, C. grandiflora, Mollugo sperguloUes, Myosotis lithosper- motdes, Spermacocce diffusa, Coronilla occidentalis, Bignonia apurensis, Pisonia pubescens, Ruellia viscosa, some new species of Jussieua, at d a new genus of the composite family, approximating to Rolandra, tie Trichoipira menthoides of M.

Their proboscis is so long that, when they fix on the lower surface of a hammock, they pierce through it and the thickest gar- ments with their sting. "We had intended to pass the night at the Vuelta del Palmito, but the number of jaguars at that part of the Apure is so great, that our Indians found two hidden behind the trunk of a locust-tree, at the moment when they were going to sling our hammocks. We were advised to re-embark, and take our station in the island of Apurito, near its junction with the Orinoco. That portion of the island belongs to the province of Caracas, while the right banks of the Apure and the Orinoco form a part, the one of the province of Varinas, the other of Spanish Gruiana. We found no trees to which we could suspend our hammocks, and were obliged to sleep on ox-hides spread on the ground. The boats were too narrow and too full oizancudos to permit us to pass the night in them. In the place where we had landed our instruments, the banks being steep, we saw new proofs of the indolence of the gallinaceous birds of the tropics. The curassaos and cashew-birds f have the habit of going down several times a-day to the river to allay their thirst. They drink a great deal, and at short intervals. A vast number of these birds had joined, near our station, a flock of parraka pheasants. They had great difficulty in climbing up the steep banks ; they attempted it several times without using their wings. We drove them before us, as if we had been driving sheep. The zamuro vultures raise themselves from the ground with great reluctance. We were singularly struck at the small quantity of water which the Bio Apure furnishes at this season to the Ori- noco. The Apure, which, according to my measurements, was still one hundred and thirty-six toises broad at the Cano Bico, was only sixty or eighty at its mouth.* Its depth * M. Latreille has discovered that the mosquitos of South Ca: olina are of the genus Simulium (Atractocera meigen.) •*• The latter (Crax pauxi) is less common than the former. Not quite so broad as the Seine at the Pont Royal, opposite th« JUNCTION WITH THE OBINOCO. 173 here was only three or four toiaes. It loses, no doubt, a part of its waters by the Rio A-richuna and the Cafio del Manati, two branches of the Apure that flow into the Fayara and the Guarico ; but its greatest loss appears to be caused by nitrations on the beach, of which we have before spoken. The velocity of the Apure near its mouth, was only 3'2 feet per second ; so that I could easily have calculated the whole quantity of the water if I had taken, by a series of proximate soundings, the whole dimensions of the tranverse section. "We touched several times on shoals before we entered the Orinoco. The ground gained from the water is immense towards the confluence of the two rivers. We were obliged to be towed along by the bank. What a contrast between this state of the river immediately before the entrance of the rainy season, when all the effects of dryness of the air and of evaporation have attained their maximum, and that autumnal state when the Apure, like an arm of the sea, covers the savannahs as far as the eye can reach! We discerned towards the south the lonely hills of Coruato; while to the east the granite rocks of Curiquima, the Sugar Loaf of Caycara, and the mountains of the Tyrant* (Cerros del Tirano) began to rise on the horizon. It was not without emotion that we beheld for the first time, after long ex- pectation, the waters of the Orinoco, at a point so distant from the coast. palace of the Tuileries, and a little more than half the width of tb« Thames at Westminster Bridge. * This name alludes, no doubt, to the expedition of Antonio Sedeno.

ON leaving the Rio Apure we found ourselves in a coun- try presenting a totally different aspect. An immense plain of' water stretched before us like a lake, as far as we could see. White-topped waves rose to the height of several feet, from the conflict of the breeze and the current. The air resounded no longer with the piercing cries of herons, flamingos, and spoonbills, crossing in long files from one shore to the other. Our eyes sought in vain those water- fowls, the habits of which vary in each tribe. All nature appeared less animated. Scarcely could we discover in the hollows of the waves a few large crocodiles, cutting obliquely, by the help of their long tails, the surface of the agitated waters. The horizon was bounded by a zone of forests, which nowhere reached so far as the bed of the river. A vast beach, constantly parched by the heat of the sun, desert and bare as the shores of the sea, resembled at a distance, from the effect of the mirage, pools of stagnant water. These sandy shores, far from fixing the limits of the river, render them uncertain, by enlarging or contracting them alternately, according to the variable action of the solar rays. In these scattered features of the landscape, in this cha- racter of solitude and of greatness, we recognize the course of the Orinoco, one of the most majestic rivers of the New World. The water, like the land, displays everywhere a characteristic and peculiar aspect. The bed of the Orinoco resembles not the bed of the Meta, the Guaviare, the Rio Negro, or the Amazon. These differences do not depend altogether on the breadth or the velocity of the current; they are connected with a multitude of impressions which it is easier to perceive upon the spot than to define with precision. Tl.us, the mere form of the waves, the tint of OEEAT BR1ADTH OF THE EIYEB. 175 th3 waters, the aspect of the sky and the clouds, would lead an experienced navigator to guess whether he were in the Atlantic, in the Mediterranean, or in the equinoctial part of the Pacific. The wind blew fresh from east-north-east. Its direc- tion was favourable for sailing up the Orinoco, towards the Mission of Encaramada; but our canoes were so ill calcu- lated to resist the shocks of the waves, that, from the violence of the motion, those who suffered habitually at sea were equally incommoded on the river. The short, broken waves are caused by the conflict of the waters at the junc- tion of the two rivers. This conflict is very violent, but far from being so dangerous as Father Grumilla describes. We passed the Punta Curiquima, which is an isolated mass of quartzose granite, a small promontory composed of rounded blocks. There, on the right bank of the Orinoco, Father Kotella founded, in the time of the Jesuits, a Mission of the Palenka and Viriviri or Gruire Indians. But during inundations, the rock Curiquima and the village at its foot were entirely surrounded by water ; and this serious incon- venience, together the sufferings of the missionaries and In- dians from the innumerable quantity of mosquitos and niguas* led them to forsake this humid spot. It is now entirely deserted, while opposite to it, on the right bank of the river, the little mountains of Coruato are the retreat of wandering Indians, expelled either from the Missions, or from tribes that are not subject to the government of the monks. Struck with the extreme breadth of the Orinoco, between the mouth of the Apure and the rock Curiquima, I ascer- tained it by means oi a base measured twice on the western beach. The bed of the Orinoco, at low water, was 1906 toises broad; but this breadth increases to 5517 toises, when, in the rainy season, the rock Curiquima, and the farm of Capuchino near the hill of Pocopocori, become islands. The swelling of the Orinoco is augmented by the impulse of the waters of the Apure, which, far from forming, like other rivers, an acute angle with the upper part of that into which it flows, meets it at right angles. We first proceeded south-west, as far as the shore inhabited • The chego \Pulcx penetrans), whicn penetrates under the nails of th« toes in men and monkeys, and there deposits it* eggs. 17G SINGULAR MOUNTAIN. by the Gruaricoto Indians on the left bank of the Orinoco, and then we advanced straight toward the south. The river, is so broad that the mountains of Encaramada appear to ri ..TO from the water, as if seen above the horizon of the sea. They form a continued chain from east to wesu. These mountains are composed of enormous blocks of granite, cleft and piled one upon another. Their division into blocks is the effect of decomposition. What contributes above all to embellish the scene at Encaramada is the luxuriance of vegetation that covers the sides of the rocks, leaving bare only their rOunded summits. They look like ancient ruins rising in the midst of a forest. The mountain immediately at the back of the Mission, the Tepupano* of the Tamanac Indians, is terminated by three enormous granitic cylinders, two of which are inclined, while the third, though worn at its base, and more than eighty feet high, has preserved a vertical position. This rock, which calls to mind the form of the Schnarcher in the Hartz mountains, or that of the Organs of Actopan in Mexico,t composed formerly a part of tho rounded summit of the mountain. In every climate, un- stratified granite separates by decomposition into blocks of prismatic, cylindric, or columnar figures. Opposite the shore of the Gluaricotos, we drew near another heap of rocks, which is very low, and three or four toises long. It rises in the midst of the plain, and has less resemblance to a tumulus than to those masses of granitic stone, which in North Holland and Germany bear the name of kunenbette, beds (or tombs) of heroes. The shore, at this Eart of the Orinoco, is no longer of pure and quartzose sand ; ut is composed of clay and spangles of mica, deposited in very thin strata, and generally at an inclination of forty or fifty degrees. It looks like decomposed mica-slate. This change in the geological configuration of the shore extends * Tepu-pano, 'place of stones,' in which we recognize tepu 'stone, rock,' as in tepu-iri ' mountain.' We here perceive that Lesgian Oigour- Tartar root tep ' stone* (found in America among the Americans, in teptl: among the Caribs, in tebou; among the Tamanacs, in tepuiri) ; a striking analogy between the languages of Caucasus and Upper Asia and those of the banks of the Orinoco. •f* In Captain Tuckey's Voyage on the river Congo, we find repre- sented a granitic rock, Taddi Ensazi, which bears a striking resemblance to the mountain of Encaramada. SA» LUIS DEL ENCAEAM1DA. 177 far beyond the mouth of the Apure. TVe had begun to observe it in this latter river as far off as Algodonal and the Cano del Manati. The spangles of mica come, no doubt, from the granite mountains of Curiquima and Encaramada ; since further north-east we find only quartzose sand, sand- stone, compact limestone, and gypsum. Alluvial earth car- ried successively from south to north need not surprise us in the Orinoco; but to what shall we attribute the same phenomenon in the bed of the Apure, seven leagues west of its mouth ? In the present state of things, notwithstanding the swellings of the Orinoco, the waters of the Apure never retrograde so far ; and, to explain this phenomenon, we are forced to admit that the micaceous strata were deposited at a time when the whole of the very low country lying be- tween Caycara, Algodonal, and the mountains of Encara- mada, formed the basin of an inland lake. We stopped some time at the port of Encaramada, which is a sort of embarcadero, a place where boats assemble. A rock of forty or fifty feet hign forms the shore. It is com- posed of blocks of granite, heaped one upon another, as at the Schneeberg in Franconia, and in almost all the granitic mountains of Europe. Some of these detached masses have a spheroidal form; they are not balls with concentric layers, but merely rounded blocks, nuclei se- parated from their envelopes by the effect of decompo- sition. This granite is of a greyish lead-colour, often black, as if covered with oxide of manganese ; but this colour does not penetrate one fifth of a line into the rock, which is of a reddish white colour within, coarse-grained, and destitute of hornblende. The Indian names of the Mission of San Luis del Encara- mada, are Guaja and Caramana* This wnall village was * All the Missions of South America have names composed of two words, the first of which is necessarily the name of a saint, the patron of the church, and the second an Indian name, that of the nation, or the spot where the establishment is placed.

These compound names appear only in official documents r the inhabitants adopt but one of the two names, and generally, provided it be sonorous, the Indian. As the names of saints are several times repeated in neighbouring places, great confusion in geography arises from these repetitions. The names of San Juau, San Diego, and San Pedro* VOL. II. IT 178 A CAEIB CHIEF. founded in 1749 by Father Gili, the Jesuit, author of the Storia delV Orinoco, published at Rome. This missionary learned in the Indian tongues, lived in these solitudes during eighteen years, till the expulsion of the Jesuits. To form a precise idea of the savage state of these countries it must be recollected that Father Gili speaks of Carichana,* which is forty leagues from Encaramada, as of a spot far distant; and that he never advanced so far as the first cataract in the river of which he ventured to undertake the description. In the port of Encaramada we met with some Caribs of Panapana. A cacique was going up the Orinoco in his canoe, to join in the famous fishing of turtles' eggs. His canoe was rounded toward the bottom like a bongo, and followed by a smaller boat called a cu/riara. He was seated beneath a sort of tent, constructed, like the sail of palm- leaves. His cold and silent gravity, the respect with which he was treated by his attendants, everything denoted him to be a person of importance. He was equipped, however, in the same manner as his Indians. They were all equally naked, armed with bows and arrows, and painted with onoto, which is the colouring fecula of the Bixa orellana. The chief, the domestics, the furniture, the boat, and the sail, were all painted red. These Caribs are men of an almost athletic stature; they appeared to us much taller than any Indians we had hitherto seen. Their smooth and thick hair, cut short on the forehead like that of choristers, their eyebrows painted black, their look at once gloomy and animated, gave a singular expression to their countenances. Having till then seen only the skulls of some Caribs of the "West India Islands preserved in the collections of Europe, we were surprised to find that these Indians, who were of pure race, had foreheads much more rounded than they are described. The women, who were very tall, and disgusting are scattered in our maps as if by chance. It is pretended that the Mission of Guaja affords a very rare example of the composition of two Spanish words. The word Encaramada means things raised one upon another, from encaramar, ' to raise up.' It is derived from the figure of Tepupano and the neighbouring rocks : perhaps it is only an Indian word caramana, in which, as in manati, a Spanish signification was believed to be discovered. * Saggio di Storia Americana, vol. i. p. 122. CROCODILES. 179 from their want of cleanliness, carried their infants on their backs. The thighs and legs of the infants were bound at certain distances by broad strips of cotton cloth, and the flesh, strongly compressed beneath the ligatures, was swelled in the interstices. It is generally to be observed, that the Caribs are as attentive to their exterior and their ornaments, as it is possible for men to be, who are naked and painted red. They attach great importance to certain configurations of the body ; and a mother would be accused of culpable indifference toward her children, if she did not employ arti- ficial means to shape the calf of the leg after the fashion of the country. As none of our Indians of A pure understood the Caribbee language, we could obtain no information from the cacique of Panama respecting the encampments that are made at this season in several islands of the Orinoco for collecting turtles' eggs. Near Encaramada a very long island divides the river into two branches. "We passed the night in a rocky creek, opposite the mouth of the Rio Cabullare, which is formed by the Payara and the Atamaica, and is sometimes considered as one of the branches of the Apure, because it commu- nicates with that river by the Rio Arichuna. The evening was beautiful. The moon illumined the tops of the granite rocks. The heat was so uniformly distributed, that, not- withstanding the humidity of the air, no twinkling of the stars was observable, even at four or five degrees above the horizon. The light of the planets was singularly dimmed ; and if, on account of the smallness of the apparent diameter of Jupiter, I had not suspected some error in the observation, I should say, that here, for the first time, we thought we distinguished the disk of Jupiter with the naked eye. Towards midnight, the north-east wind became extremely violent. It brought no clouds, but the vault of the sky was covered more and more with vapours. Strong gusts were felt, and made us fear for the safety of our canoe. During this whole day we had seen very few crocodiles, but all of an extraordinary size, from twenty to twenty-four feet. The Indians assured us that the young crocodiles prefer the marshes, and the rivers that are less broad, and less deep. They crowd together particularly in the Caftos, and we may •ay of tlnm, what Abdallatif says of the crocodiles of the > 2 180 MOUNTAINS OF ENCARAMADA. Nile,* "that they swarm like worms in the shallow waters of the riyer, and in the shelter of uninhabited islands." On the 6th of April, whilst continuing to ascend the Orinoco, first southward and then to south-west, we perceived the southern side of the Serrania, or chain of the mountains of Encaramada. The part nearest the river is only one hundred and forty or one hundred and sixty toises high ; but from its abrupt declivities, its situation in the midst of a savannah, and its rocky summits, cut into shapeless prisms, the Serrania appears singularly elevated. Its greatest breadth is only three leagues. According to information given me by the Indians of the Pareka nation, it is con- siderably wider toward the east. The summits of Encara- mada form the northernmost link of a group of mountains which border the right bank of the Orinoco, between the la- titudes of 5° and 7° 30' from the mouth of the Bio Zama to that of the Cabullare. The different links into which this group is divided are separated by little grassy plains. They do not preserve a direction perfectly parallel to each other ; for the most northern stretch from west to east, and the most southern from north-west to south-east. This change of direction sufficiently explains the increase of breadth observed in the Cordillera of Parime towards the east, between the sources of the Orinoco and of the Bio Paruspa. On penetrating beyond the great cataracts of Atures and of Maypures, we shall see seven principal links, those of Encaramada or Sacuina, of Chaviripa, of Baraguan, of Cari- chana, of Uniama, of Calitamini, and of Sipapo, successively appear. This sketch may serve to give a general idea of the geological configuration of the ground. We recognize everywhere on the globe a tendency toward regular forms, in those mountains that appear the most irregularly grouped. Every link appears, in a transverse section, like a distinct summit, to those who navigate the Orinoco ; but this divi- sion is merely in appearance. The regularity in the direc- tion and separation of the links seems to diminish in pro- portion as we advance towards the east. The mountains of Encaramada join those of Mato, which give birth to the Bio Asiveru or Cuchivero; those of Chaviripe are pro- longed by the granite chain of the Corosal, of Amoco, and * Description de 1'Egypte, translated by De Secy. THE FABLED EL DORADO. 181 of Murcielago, towards the sources of tho Erevato and the Ventuari. It was across these mountains, which are inhabited by Indians of gentle character, employed in agriculture,* that, at the time of the expedition for settling boundaries, General Iturriaga took some horned cattle for the supply of the new town of San Fernando de Atabapo. The in- habitants of Encaramada then showed the Spanish soldiers the way by the Rio Manapiari,f which falls into the Ven- tuari. By descending these two rivers, the Orinoco and the A tabapo may be reached without passing the great cataracts, which present almost insurmountable obstacles to the con- veyance of cattle. The spirit of enterprise which had so eminently distinguished the Castilians at the period of the discovery of America, was again roused for a time in the middle of the eighteenth century, when Ferdinand VI was desirous of knowing the true limits of his vast possessions ; and in the forests of Gruiana, that land of fiction and fabulous tradition, the wily Indians revived the chimerical idea of the wealth of El Dorado, which had so much occu- pied the imagination of the first conquerors. Amidst the mountains of Encaramada, which, like most coarse-grained granite rocks, are destitute of metallic veins, we cannot help inquiring whence came those grains of gold which Juan Martinez J and Raleigh profess to have seen in such abundance in the hands of the Indians of the Orinoco. From what I observed in that part of America, I am led to think that gold, like tin,|| is sometimes disseminated in an * The Mapoyes, Parecag, Javaranas, and Curacicanas, who possess fine plantations (conucos) in the savannahs by which these forests are bounded. f Between Encarmada and the Rio Manapiare, Don Miguel Sanchez, chief of this little expedition, crossed the Rio Guainaima, which flows into the Cuchivero.

Not long a^o the Indians of Encaramada found in the Quebrada del Tigre* a piece of native gold two lines in diameter. It was rounded, and appeared to have been washed along by the waters. This discovery excited the attention of the mis- sionaries much more than of the natives ; it was followed by no other of the same kind. 1 cannot quit this first link of the mountains of Enca- ramada without recalling to mind a fact that was not un- known to Father Gili, and which was often mentioned to ine during our abode in the Missions of the Orinoco. The natives of those countries have retained the belief that, " at the time of the great waters, when their fathers were forced to have recourse to boats, to escape the general inundation, the waves of the sea beat against the rocks of Encaramada." This belief is not confined to one nation singly, the Tama- ntcs ; it makes part of a system :of historical tradition, of which we find scattered notions among the Maypures of the great cataracts ; among the Indians of the Bio Erevato, which runs into the Caura ; and among almost all the tribes of the Upper Orinoco. When the Tamanacs are asked how the human race survived this great deluge, the ' age of water,' of the Mexicans, they say, "a man and a woman saved themselves on a high mountain, called Tamanacu, situated on the banks of the Asiveru ; and casting behind them, over their heads, the fruits of the mauritia palm-tree, they saw the seeds contained in those fruits produce men and women, who repeopled the earth." Thus we find in all its simpli- city, among nations now in a savage state, a tradition which the Greeks embellished with all the charms of imagination ! A few leagues from Encaramada, a rock, called Tcpu-mereme, or ' the painted rock,' rises in the midst of the savannah. Upon it are traced representations of animals, and symbolic figures resembling those we saw in going down the Orinoco, at a small distance below Encaramada, near the town Cay- cara. Similar rocks in Africa are called by travellers fetis h stones. I shall not make use of this term, because fetishism does not prevail among the natives of the Orinoco ; and the * The Tiger-ravine. BIMILABITY OF THE LEGENDS. 183 figures of stars, of the sun, of tigers, and of crocodiles, which we found traced upon the rocks in spots now uninhabited, appeared to me in no way to denote the objects of worship of those nations. Between the banks of the Cassiquiare and the Orinoco, between Encaramada, the Capuchino, and Caycara, these hieroglyphic figures are often seen at great heights, on rocky cliffs which could be accessible only by constructing very lofty scaffolds. When the natives are asked how those figures could have been sculptured, they answer with a smile, as if relating a fact of which only a white man could be ignorant, that "at the period of the great waters, their fathers went to that height in boats." These ancient traditions of the human race, which we find dispersed over the whole surface of the globe, like the relics of a vast shipwreck, are highly interesting in the philo- sophical study of our own species. Like certain families of the vegetable kingdom, which, notwithstanding the diversity of climates and the influence of heights, retain the impres- sion of a common type, the traditions of nations respecting the origin of the world, display everywhere the same phy- siognomy, and preserve features of resemblance that fill us with astonishment. How many different tongues, belonging to branches that appear totally distinct, transmit to us the same facts ! The traditions concerning races that have been destroyed, and the renewal of natnre, scarcely vary in reality, though every nation gives them a local colouring. In the great continents, as in the smallest islands of the Pacific Ocean, it is always on the loftiest and nearest moun- tain that the remains of the human race have been saved ; and this event appears the more recent, in proportion as the nations are uncultivated, and as the knowledge they have of their own existence has no very remote date. After having studied with attention the Mexican monuments anterior to the discovery of the New "World ; after havLi» penetrated into the forests of the Orinoco, and obsened the diminutive size of the European establishments, their solitude, and the state of the tribes that have remained •'ndependent ; we cannot allow ourselves to attribute the analogies just cited to the influence exercised by the mis- sionaries, and by Christianity, on the national traditions. Nor IB it more probable, that the d.scovery of eea-shellfl on 184 INDIAN ENCAMPMEHT. the summit of mountains gave birth, among the nations of the Orinoco, to the tradition of some great inundation which extinguished for a time the germs of organic life on our globe. The country that extends from the right bank of the Orinoco to the Cassiquiare and the Eio Negro, is a country of primitive rocks. I saw there one small formation of sandstone or conglomerate ; but no secondary limestone, and no trace of petrifactions. A fresh north-east breeze carried us full-sail towards the Boca de la Tortnga. We landed, at eleven in the morn- ing, on an island which the Indians of the Missions of Uru- ana considered as their property, and whicli lies in the middle of the river. This island is celebrated for the turtle fishery, or, as they say here, the cosecha, l the harvest [of eggs,]' that takes place annually. "We here found an assemblage of Indians, encamped under huts made of palm-leaves. This encampment contained more than three hundred persons. Accustomed, since we had left San Fernando de Apure, to see only desert shores, we were singularly struck by the bustle that prevailed here. We found, besides the Guamos and the Ottomacs of Uruana, who are both considered as savage races, Caribs and other Indians of the Lower Orinoco. Every tribe was separately encamped, and was distinguished by the pigments with whicK their skins were painted. Some white men were seen amidst this tumultuous assemblage, chiefly pulperos, or little traders of Angostura, who had come up the river to purchase turtle oil from the natives. The missionary of Uruana, a native of Alcala, came to meet us, and he was extremely astonished at seeing us. After having admired our instruments, he gave us an exaggerated picture of the sufferings to which we should be necessarily exposed in ascending the Orinoco beyond the cataracts. The object of our journey appeared to him very mysterious. " How is it possible to believe," said he, " that you have left your country, to come and be devoured by mosquitos on this river, and to measure lands that are not your own ? " We were happily furnished with recommendations from the Superior of the Franciscan Mis- sions, and the brother-in-law of the governor of Varinas, who accompanied us, soon dissipated the doubts to which our dress, our accent, and our arrival in this sandy island, HABYE8T OF Tl RTLE-EGG8. 185 had given rise among the Whites. The missionary invited us to partake a frugal repast of fish and plantains. He told us that he had come to encamp with the Indians during the time of the * harvest of eggs,' " to celebrate mass every morning in the open air, to procure the oil necessary for the church-lamps, and especially to govern this mixed republic (renublica de Indies y Castellanos) in which every one wished to profit singly by what God had granted to all." We made the tour of the island, accompanied by the missionary and by a pulpero, who boasted of having, for ten successive years, visited the camp of the Indians, and at- tended the turtle-fishery. We were on a plain of sand per- fectly smooth ; and were told that, as far as we could see along the beach, turtles' eggs were concealed under a layer of earth. The missionary carried a long pole in his hand. He showed us, that by means of this pole, the extent of the stratum of eggs could be determined as accurately as the miner determines the limits of a bed of marl, of bog iron- ore, or of coal. On thrusting the rod perpendicularly into the ground, the sudden want of resistance shows that the cavity or layer of loose earth containing the eggs, has been reached. We saw that the stratum is generally spread with so much uniformity, that the pole finds it everywhere in a radius of ten toises around any given spot. Here they talk continually of square perches of eggs ; it is like a mining- country, divided into lots, and worked with the great- est regularity. The stratum of eggs, however, is far from covering the whole island : they are not found wherever the ground rises abruptly, because the turtle cannot mount heights. I related to my guides the emphatic description of Father G-umilla, who asserts, that the shores of the Orinoco contain fewer grains of sand than the river con- tains turtles ; and that these animals would prevent vessels from advancing, if men and tigers did not annually destroy so great a number.* " Son cuentos de frailes" " they are * " It would be as difficult to count the grains of sand on the shores of the Orinoco, as to count the immense number of tortoises which inhabit its margins and waters. Were it not for the vast consumption of tor- toises and their eggs, the river Orinoco, despite its great magnitude, would be unnavigable, for vessels would be impeded by the enormous multitude of the tortoises." — Gumilla, Orinoco Illustrata, vol L pp. 331-336. 186 DIFFERENT SPECIES OF TORTOISES.' monkish legends," said the pulpero of Angostura, in a low roice ; for the only travellers in this country being the missionaries, they here call ' monks' stories,' what we call 1 travellers' tales,' in Europe. The Indians assured us that, in going up the Orinoco from its mouth to its junction with the Apure, not one island or one beach is to be found, where eggs can be collected in abundance. The great turtle (arrau)* dreads places inha- bited by men, or much frequented by boats. It is a timid and mistrustful animal, raising only its head above the water, and hiding itself at the least noise. The shores where almost all the turtles of the Orinoco appear to assemble annually, are situated between the junction of the Ori- noco with the Apure, and the great cataracts ; that is to say, between Cabruta and the Mission of Atures. There are found the three famous fisheries ; those of Encaramada, or Boca del Cabullare ; of Cucuruparu, or Boca de la Tor- tuga ; and of Pararuma, a little below Carichana. It seems that the arrau does not pass beyond the cataracts ; and we were assured, that only the turtles called terekay, (in Spanish terecayas,} are found above Atures and Maypures. The arrau, called by the Spaniards of the Missions simply tortuga, is an animal whose existence is of great importance to the nations on the Lower Orinoco. It is a large fresh- water tortoise, with palmate and membraneous feet; the head very flat, with two fleshy and acutely-pointed append- ages under the chin ; five claws to the fore feet, and four to the hind feet, which are furrowed underneath. The upper shell has five central, eight lateral, and twenty-four marginal plates. The colour is darkish grey above, and orange beneath. The feet are yellow, and very long. There is a deep furrow between the eyes. The claws are very strong and crooked. The anus is placed at the distance of one-filth from the extremity of the tail. The full-grown animal weighs from forty to fifty pounds. Its eggs are much larger than those of pigeons, and less elongated than the eggs of the terekay. They are covered with a calcareous crust, and, it is * This word belongs to the Maypure language, and must not be con- founded with arua, which means a crocodile, among the Tamanacs, neighbours of the Maypures. The Ottomacs call the turtle of Uruana, achea ; the Tamanacs, peje. SEASON OF LAYING. 187 paid, they have sufficient firmness for the children of the Ottomac Indians, who are great players at ball, to throw them into the air from one to another. If the arrau inhabited the bed of the river above the cataracts, the Indians of the Upper Orinoco would not travel so far to procure the flesh and the eggs of this tortoise. Yet, formerly, whole tribea from the Atabapo and the Cassiquiare have been known to pass the cataracts, in order to take part in the fishery at Uruana. The terekay is less than the arrau. It is in general only fourteen inches in diameter. The number of plates in the upper shell is the same, but they are somewhat differently arranged. I counted three in the centre of the disk, and five hexagonal on each side. The margins contain twenty- four, all quadrangular, and much curved. The upper shell is of a black colour inclining to green ; the feet and claws are like those of the arrau. The whole animal is of an olive-green, but it has two spots of red mixed with yellow on the top of the head. The throat is also yellow, and fur- nished with a prickly appendage. The terekays do not assemble in numerous societies like the arraus, to lay tneir eggs in common, and deposit them upon the same shore. The eggs of the terekay have an agreeable taste, and are much sought after by the inhabitants of Spanish Guiana. They are found in the Upper Orinoco, as well as below the cataracts, and even in the A pure, the Uritucu, the Guarico, and the small rivers that traverse the Llanos of Caracas. The form of the feet and head, the appendages of the chin and throat, and the position of the anus, seem to indicate that the arrau, and probably the terekay also, belong to a new subdivision of the tortoises, that may be separated from the emydes. The period at which the large arrau tortoise lays its eggs coincides with the period of the lowest waters. The Orinoco beginning to increase from the vernal equinox, the lowest flats are found uncovered from the end of Ja- nuary till the 20th or 25th of March. The arrau tor- toises collect in troops in the month of January, then issue from the water, and warm themselves in the sun, reposing on the sands. The Indians belieye that great heat is in- dispensable to the health of the animal, and that its expo- 188 METHOD OF DEPOSITING THE EGGS. eure to the sun favours the laying of the eggs. The arram are found on the beach a great part of the day during the whole month of February. At the beginning of March the straggling troops assemble, and swim towards the small num- ber of islands on which they habitually deposit their eggs. It is probable that the same tortoise returns every year to the same locality. At this period, a few days before they lay their eggs, thousands of these animals may be seen ranged in long files, on the borders of the islands of Cucu- ruparu, Uruana, and Pararuma, stretching out their necks and holding their heads above water, to see whether they have anything to dread. The Indians, who are anxious that the bands when assembled should not separate, that the tortoises should not disperse, and that the laying of the eggs should be performed tranquilly, place sentinels at cer- tain distances along the shore. The people who pass in boats are told to keep in the middle of the river, and not frighten the tortoises by cries. The laying of the eggs takes place always during the night, and it begins soon after sunset. "With its hind feet, which are very long, and fur- nished with crooked claws, the animal digs a hole of three feet in diameter and two in depth. These tortoises feel so pressing a desire to lay their eggs, that some of them descend into holes that have been dug by others, but which are not yet covered with earth. There they deposit a new layer of eggs on that which has been recently laid. In this tumultuous movement an immense number of eggs are broken. The missionary showed us, by removing the sand in several places, that this loss probably amounts to a fifth of the whole quantity. The yolk of the broken eggs con- tributes, in drying, to cement the sand ; and we found very large concretions of grains of quartz and broken shells. The number of animals working on the beach during the night is so considerable, that day surprises many of them before the laying of their eggs is terminated. They are then urged on by the double necessity of depositing their eggs, and closing the holes they have dug, that they may not be perceived by the jaguars. The tortoises that thus remain too late are insensible to their own danger. They work in the presence of the Indians, who visit the beach THEIR ENORMOUS ABUNDANCE. 189 at a very early hour, and who call them ' inad tortoises.' Notwithstanding the rapidity of their movements, they are then easily caught with the hand. The three encampments formed by the Indians, in the places indicated above, begin about the end of March or commencement of April. The gathering of the eggs is con- ducted in a uniform manner, and with that regularity which characterises all monastic institutions. Before the arrival of the missionaries on the banks of the river, the Indians pro- fited much less from a production which nature has sup- plied in such abundance. Every tribe searched the beach in its own way; and an immense number of eggs were use- lessly broken, because they were not dug up with precau- tion, and more eggs were uncovered than could be carried away. It was like a mine worked by unskilful hands. The Jesuits have the merit of having reduced this operation to regularity; and though the Franciscan monks, who suc- ceeded the Jesuits in the Missions of the Orinoco, boast of having followed the example of their predecessors, they unhappily do not effect all that prudence requires. The Jesuits cud not suffer the whole beach to be searched ; they left a part untouched, from the fear of seeing the breed of arrau tortoises, if not destroyed, at least considerably dimi- nished. The whole beach is now dug up without reserve ; and accordingly it seems to be perceived that the gathering is less productive from year to year. When the camp is formed, the missionary of Uruana names his lieutenant, or commissary, who divides the ground where the eggs are found into different portions, according to the number of the Indian tribes who take part in the gathering. They are all ' Indians of Missions,' as naked and rude as the * Indians of the woods ;' though they are called reducidos and neqfitos, because they go to church at the sound of the bell, and have learned to kneel down during the consecration of the host. The lieutenant (commissionado del Padre) begins his operations by sounding. He examines by means of a long wooden pole or a cane of bamboo, how far the stratum of eggs extends. This stratum, according to our measurements, extended to the distance of one hundred and twenty feet from the shore. Its average depth is three feet. The commit- 190 PRODUCE OF TIIE ISLAND. sionado places marks to indicate the point where each tribe should stop in its labours. We were surprised to hear this * harvest of eggs ' estimated like the produce of a well- cultivated field. An area accurately measured of one hun- dred and twenty feet long, and thirty feet wide, has been known to yield one hundred jars of oil, valued at about forty pounds sterling. The Indians remove the earth with their hands ; they place the eggs they have collected in small baskets, carry them to their encampment, and throw them into long troughs of wood filled with water. In these troughs the eggs, broken and stirred with shovels, remain exposed to the sun till the oily part, which swims on the surface, has time to inspissate. As fast as this collects on the surface of the water, it is taken off and boiled over a quick fire. This animal oil, called tortoise butter (manteca de tortugas)* keeps the better, it is said, in proportion as it has undergone a strong ebullition. When well prepared, it is limpid, inodorous, and scarcely yellow. The missiona- ries compare it to the best olive oil, and it is used not merely for burning in lamps, but for cooking. It is not easy, however, to procure oil of turtles' eggs quite pure. It has generally a putrid smell, owing to the mixture of eggs in which the young are already formed. I acquired some general statistical notions on the spot, by consulting the missionary of Uruana, his lieutenant, and the traders of Angostura. The shore of Uruana furnishes one thousand botijas, or jars of oil, annually. The price of each jar at Angostura varies from two piastres to two and a half. We may admit that the total produce of the three shores, where the cosecha, or gathering of eggs, is annually made, is five thousand botijas. Now as two hundred eggs yield oil enough to fill a bottle (limeta), it requires five thousand eggs for a jar or botija of oil. Estimating at one hundred, or one hundred and sixteen, the number of eggs that one tortoise produces, and reckoning that one third of these is broken at the time of laying, particularly by the 'mad tortoises,' we may presume that, to obtain annually fiv° thousand jars of oil, three hundred and thirty thousand arrau tortoises, the weight of which amounts to one hundred * The Tamaiac Indians give it the name of carapa ; the MaypuroF eaU if timi. i: CONGREGATION CF THE NATIVES. 191 and sixty-five thousand quintals, must lay thirty-three millions of eggs on the three shores where this harvest is gathered. The results of these calculations are much below the truth. Many tortoises lay only sixty or seventy eggs ; and a great number of these animals are devoured by jaguars at the moment they emerge from the water. The Indians bring away a great number of eggs to eat them dried in the sun; and they break a considerable number through carelessness during the gathering. The number of eggs that are hatched before the people can dig them up is so prodigious, that near the encampment of Uruana I saw the whole shore of the Orinoco swarming with little tor- toises an inch in diameter, escaping with difficulty from the pursuit of the Indian children. If to these considerations be added, that all the arraus do not assemble on the three shores of the encampments ; and that there are many which lay their eggs in solitude, and some weeks later,* between the mouth of the Orinoco and the confluence of the Apure ; we must admit that the number of turtles which annually deposit their eggs on the banks of the Lower Orinoco, is near a million. This number is very great for so large an animal. In general large animals moltiply less considerably than the smaller ones. The labour of collecting the eggs, and preparing the oil, occupies three weeks. It is at this period only that the mis- sionaries have any communication with the coast and the civilized neighbouring countries. The Franciscan monks who live south of the cataracts, come to the 'harvest of eggs' less to procure oil, than to see, as they say, 'white faces ;' and to learn whether the king inhabits the Escurial or San Ildefonso, whether convents are still suppressed in France, and above all, whether the Turks continue to keep quiet. On these subjects, (the only ones interesting * The arraus, which lay their eggs before the beginning of March, (for in the same species the more or less frequent basking in the sun, the food, and the peculiar organization of each individual, occasion differ- ences,) come out of the water with the terekays, which lay in January and February. Father Gurrilla believes them to be arraus that were not able to lay their eggs the preceding year. It is difficult to find the eggs of the terekays, because these animals, far from collecting in thousand! on the same beach, de-posit their eggs as they are scattered about. 192 ENEMIES OF THE TOETOISB. to a monk of the Orinoco), the small traders rf Angostura, who visit the encampments, can give, unfortunately, no very exact information. But in these distant countries no doubt is. ever entertained of the news brought by a white man from the capital. The profit of the traders in oil amounts to seventy or eighty per cent. ; for the Indians sell it them at the price of a piastre a jar or botija, and the expense of carriage is not more than two-fifths of a piastre per jar. The Indians bring away also a considerable quantity of eggs dried in the sun, or slightly boiled. Our rowers had baskets or little bags of cotton-cloth filled with these eggs. Their taste is not disagreeable, when well preserved. We were shown large shells of turtles, which had been destroyed by the jaguars. These animals follow the arraus towards those places on the beach where the eggs are laid. They surprise the arraus on the sand; and, in order to devour them at their ease, turn them in such a manner that the under shell is uppermost. In this situation the turtles cannot rise ; and as the jaguar turns many more than he can eat in one night, the Indians often avail themselves of his cunning and avidity. When we reflect on the difficulty experienced by the naturalist in getting out the body of the turtle without separating the upper and under shells, we cannot sufficiently wonder at the suppleness of the tiger's paw, which is able to remove the double armour of the arrau, as if the adhering parts of the muscles had been cut by a surgical instrument. The jaguar pursues the turtle into the water when it is not very deep. It even digs up the eggs; and together with the crocodile, the heron, and the galinazo vulture, is the most cruel enemy of the little turtles recently hatched. The island of Pararuma had been so much infested with croco- diles the preceding year, during the egg-harvest, that the Indians in one night caught eighteen, of twelve or fifteen feet long, by means of curved pieces of iron, baited with the flesh of the manati. Besides the beasts of the forests we have just named, the wild Indians also very much diminisl the quantity of the oil. Warned by the first slight rains, which they call 'turtle-rains' (peje canepori),* they hastei to the banks of the Orinoco, and kill the turtles with poi • * In the Tamanac language, from peje, a tortoise, and canepo, rain. THE TO UNO TORTOISES. 193 soned arrows, whilst, with upraised heads and paws ex- tcmled. the animals are wanning themselves in the sun. Though the little turtles (tortuguillos) may have burst the shells of their eggs during the day, they are never seen to come out of the ground but at night. The Indians assert that the young animal fears the heat of the sun. They tried also to show us, that when the tortuguillo is carried in a bag to a distance from the shore, and placed in such a manner that its tail is turned to the river, it takes without hesitation the shortest way to the water. I confess, that this experiment, of which Father Gumilla speaks, does not always succeed equally well : yet in general it does appear that at great distances from the shore, and even in an island, these little animals feel with extreme delicacy in what direction the most humid air prevails. Reflecting on the almost uninterrupted layer of eggs that extends along the beach, and on the thousands of little turtles that seek the water as soon as they are hatched, it is difficult to admit that the many turtles which have made their nests in the same spot, can distinguish their own young, and lead them, like the crocodiles, to the lakes in the vicinity of the Orinoco. It is certain, however, that the animal passes the first years of its life in pools where the water is shallow, and does not return to the bed of the threat river till it is full-grown. How then do the tortuguillos find these pools ? Are they led thither by female turtles, which adopt the young as by chance ? The crocodiles, less numerous, deposit their eggs in separate holes; and, in this family of saurians, the female returns about the time when the incubation is terminated, calls her young, which answer to her voice, and often assists them to get out of the ground. The arrau tortoise, no doubt, like the crocodile, knows the spot where she has made her nest; but, not daring to return to the beach on which the Indians have formed their encampment, how can she distinguish her own young from those which do not belong to her? On the other hand, the Ottomac Indians declare that, at the period of inun- dation, they have met with female turtles followed by a great number of young ones. These were perhaps arraus whose eggs had been deposited on a desert beach to which they could return. Mules are extremely rare among these VOL. IJ O 104 DANGEROUS ACCIDENT. animals. Scarcely 18 one male found among several hun- dred females. The cause of this disparity cannot be the same as with the crocodiles, which fight in the coupling season. Our pilot had anchored at the Playa de huevos, to pur- chase some provisions, our store having began to run short. We found there fresh meat, Angostura rice, and even biscuit made of wheat-flour. Our Indians filled the boat with little live turtles, and eggs dried in the sun, for their own use. Having taken leave of the missionary of Uruana, who had treated us with great kindness, we set sail about four in the afternoon. The wind was fresh, and blew in squalls. Since we had entered the mountainous part of the country, we had discovered that our canoe carried sail very badly ; but the master was desirous of showing the Indians who were assembled on the beach, that, by going close to the wind, he could reach, at one single tack, the middle of the river. At the very moment when he was boasting of hia dexterity, and the boldness of his manoeuvre, the force of the wind upon the sail became so great that we were on the point of going down. One side of the boat was under water, which rushed in with such violence that it was soon up to our knees. It washed over a little table at which I was writing at the stern of the boat. I had some difficulty to save my journal, and in an instant we saw our books, papers, and dried plants, all afloat. M. Bonpland was lying asleep in the middle of the canoe. Awakened by the entrance of the water and the cries of the Indians, he understood the danger of our situation, whilst he maintained that coolness which he always displayed in the most difficult circumstances. The lee-side righting itself from time to time during the squall, he did not consider the boat as lost. He thought that, were we even forced to abandon it, we might save our- selves by swimming, since there was no crocodile in sight. Amidst this uncertainty the cordage of the sail suddenly gave way. The same gust of wind, that had thrown us on our beam, served also to right us. "We laboured to bale the water out of the boat with calabashes, the sail was again set, and in less than half an hour we were in a state to proceed. The wind now abated a little. Squalls alternating with dead calms are common in that part of the Orinoco which BOLDNESS OP JAGUARS. 195 IB bordered by mountains. They are very dangerous for boats deeply laden, and without decks. We had escaped as if by miracle. To the reproaches that were heaped on our pilot for having kept too near the wind, he replied with the phlegmatic coolness peculiar to the Indians, observing "that the whites would find sun enough on those banks to dry their papers." We lost only one book — the first volume of the ' Genera Plantarum ' of Schreber — which had fallen overboard. At nightfall we landed on a barren island in the middle of the river, near the Mission of Uruana. We supped in a clear moonlight, seating ourselves on some large turtle-shells that were found scattered about the beach. What satisfaction we felt on finding ourselves thus comfortably landed! We figured to ourselves the situation of a man who had been saved alone from ship- wreck, wandering on these desert shores, meeting at every step with other rivers which fall into the Orinoco, and which it is dangerous to pass by swimming, on account of the multitude of crocodiles and caribe fishes. We pictured to ourselves such a man, alive to the most tender affections of the soul, ignorant of the fate of his companions, and thinking more of them than of himself. If we love to indulge such melancholy meditations, it is because, when just escaped from danger, we seem to feel as it were the necessity of strong emotions. Our minds were full of what we had just witnessed. There are periods in life when, with- out being discouraged, the future appears more uncertain. It was only three days since we had entered the Orinoco, and there yet remained three months for us to navigate rivers encumbered with rocks, and in boats smaller than that in which we had so nearly perished. The night was intensely hot. We lay upon skins spread on the ground, there being no trees to which we could fasten our hammocks. The torments of the mosquitos increased every day; and we were surprised to find that on this spot our fires did not prevent trie approach of the jaguars. They swam across the arm of the river that sepa- rated us from the mainland. Towards morning we heard their cries very near. They had come to the island when we passed the night. The Indians told us that, during the collecting of the turtles' eggs, tigers are always more fre« o 2 196 coircEPCioir DE URBANA. quent in those regions, and display at that period the greatest intrepidity. On the following day, the 7th, we passed, on our right, the mouth of the great Bio Auraca, celebrated for the immense number of birds that frequent it; and, on our left, the Mission of Uruana, commonly called La Concepcion de Ur- lana. This small village, which contains five hundred souls, was founded by the Jesuits, about the year 1748, by the union of the Ottomac and Cavere Indians. It lies at the foot of a mountain composed of detached blocks of granite, which, I believe, bears the name of Saraguaca. Masses of rock, separated one from the other by the effect of decom- position, form caverns, in which we find indubitable proofs of the ancient civilization of the natives. Hieroglyphic figures, and even characters in regular lines, are seen sculp- tured on their sides; though I doubt whether they bear any analogy to alphabetic writing. We visited the Mission of Uruana on our return from the Bio Negro, and saw with our own eyes those heaps of earth which the Ottomacs eat, and which have become the subject of such lively discussion in Europe.* On measuring the breadth of the Orinoco between the islands called Isla de Uruana and Isla de la Manteca, we found it, during the high waters, 2674 toises, which make nearly four nautical miles. This is eight times the breadth of the Nile at Manfalout and Syout, yet we were at the distance of a hundred and ninety-four leagues from the mouth of the Orinoco. The temperature of the water at its surface was 27' 8° of the centigrade thermometer, near Uruana. That of the river Zaire, or Congo, in Africa, at an equal distance from the equator, was found by Captain Tuckey, in the months of July and August, to be only from 23'9° to 25'6°. The western bank of the Orinoco remains low farther * This earth is a greasy kind of clay, which, in seasons of scarcity, the natives use to assuage the cravings of hunger ; it having been proved by their experience as well as by physiological researches, that want of food can be more easily borne by filling the cavity of the stomach with some substance, even although it may be in itself very nearly or totally innu- tritions. The Indian hunters of North America, for the same purpose, tie boards tightly across the abdomen ; and most savage races are found to have recourse to expedients that answer the same end. BUMMER-SLEEP OF CROCODILES. 197 than the mouth of the Meta; while from the Mission of Uruana t ic mountains approach the eastern bank more and •more. As the strength of the current increases in propor- tion as the river grows narrower, the progress of our boat became much slower. We continued to ascend the Orinoco under sail, but the high and woody grounds deprived us of the wind. At other times the narrow passes between the mountains by which we sailed, sent us violent gusts, but of short duration. The number of crocodiles increased below the junction of the Bio Arauca, particularly opposite the great lake of Capanaparo, which communicates with the Orinoco, as the Laguna de CabuUarito communicates at the same time with the Orinoco and the Eio Arauca. The Indians told us that the crocodiles came from the inlands, where they had been buried in the dried mud of the savannahs. As soon as the first showers arouse them from their lethargy, they crowd together in troops, and hasten toward the river, there to disperse again. Here, in the equinoctial zone, it is the increase of humidity that recalls them to life ; while in Georgia and Florida, in the temperate zone, it is the augmentation of heat that rouses these animals from a state of nervous and muscular debility, during which the active powers of respiration are suspended or singularly diminished. The season of great drought, im- properly called the summer of the torrid zone, corresponds with the winter of the temperate zone ; and it is a curious physiological phenomenon to observe the alligators of North America plunged into a winter-sleep by excess of cold, at the same period when the crocodiles of the Llanos begin their siesta or summer-sleep. If it were probable that these animals of the same family had heretofore inhabited the same northern country, we might suppose that, in ad- vancing towards the equator, they feel the want of repose after having exercised their muscles for seven or eight months, and that they retain under a new sky the habits which appear to be essentially linked with their organization. Having passed the mouths of the channels communicat- ing with the lake of Capanaparo, we entered a part of the Orinoco, where the bed of the river is narrowed by the mountains of Baraguan. It is a kind of strait, reaching 198 PASSAGE OF B/.RA GUAff. nearly to the confluence of the Rio Suapure. From these granite mountains the natives heretofore gave the name of Baraguan to that part of the Orinoco comprised between the mouths of the Arauca and the Atabapo. Among savage nations great rivers bear different denominations in the different portions of their course. The Passage of Baraguan presents a picturesque scene. The granite rocks are perpendicular. They form a range of mountains lying north-west and south-east ; and the river cutting this dyke nearly at a right angle, the summits of the mountains appear like separate peaks. Their elevation in general does not surpass one hundred and twenty toises ; but their situa- tion in the midst of a small plain, their steep declivities, and their flanks destitute of vegetation, give them a majestic character. They are composed of enormous masses of granite of a parallelopipedal figure, but rounded at the edges, and heaped one upon another. The blocks are often eighty feet long, and twenty or thirty broad. They would seem to have been piled up by some external force, if the proximity of a rock identical in its composition, not sepa- rated into blocks but filled with veins, did not prove that the parallelopipedal form is owing solely to the action of the atmosphere. These veins, two or three inches thick, are distinguished by- a fine-grained quartz-granite crossing a coarse-grained granite almost porphyritic, and abounding in fine crystals of red feldspar. I sought in vain, in the Cordillera of Baraguan, for hornblende, and those steatitic masses that characterise several granites of the Higher Alps in Switzerland. We landed in the middle of the strait of Baraguan to measure its breadth. The rocks project so much towards the river that I measured with difficulty a base of eighty toises. I found the river eight hundred and eighty-nine toises broad. In order to conceive how this passage bears the name of a strait, we must recollect that the breadth of the river from Uruana to the junction of the Meta is in general from 1500 to 2500 toises. In this place, which is extremely hot and barren, I measured two granite summits, much rounded : one was only a hundred and ten, and the other eighty-five, toises. There are higher summits in the NOON IN TUB TEOPIC8. 199 interior of the group, but in general these mountains, of so wild an aspect, have not the elevation that is assigned to them by the missionaries. We looked in vain for plants in the clefts of the rocks, which are as steep as walls, and furnish some traces of stratification. We found only an old trunk of aubletia,* with large apple-shaped fruit, and a new species of the family of the apocyneaB.t All the stones were covered with :tn innumerable quantity of iguanas and geckos with spread- ing and membranous fingers. These lizards, motionless, with heads raised, and mouths open, seemed to suck in the heated air. The thermometer placed against the rock rose to 5O2°. The soil appeared to undulate, from the effect of mirage, without a breath of wind being felt. The sun was near the zenith, and its dazzling light, reflected from the sur- face of the river, contrasted with the reddish vapours that enveloped every surrounding object. How vivid la *he im- pression produced by the calm of nature, at noon, in these burning climates ! The beasts of the forests retire to the thickets ; the birds hide themselves beneath the foliage of the trees, or in the crevices of the rocks. Yet, amidst tliis apparent silence, when we lend an attentive ear to the most feeble sounds transmitted through the air, we hear a dull vibration, a continual murmur, a hum of insects, filling, if we may use the expression, all the lower strata of the air. Nothing is better fitted to make man feel the extent and power of organic life. Myriads of insects creep upon the soil, and nutter round the plants parched by the heat of the sun. A confused noise issues from every bush, from the decayed trunks of trees, from the clefts of the rocks, and from the ground undermined by lizards, millepedes, and cecilias. These are so many voices proclaiming to us that all nature breathes; and that, under a thousand different forms, life is diffused throughout the cracked and dusty soil, as well as in the bosom of the waters, and in the air that circulates around us. The sensation* which I here recall to mind are not unknown to those who, without having advanced to the enuator, have visited Italy, Spain, or Egypt. That contrast ot motion and silence, that aspect of nature at once cabn ana • Aabletia tiburba. f Allamanda 200 FETID RITER- WATER animated, strikes the imagination of the traveller when enters the basin of the Mediterranean, within the zone of olives, dwarf palms, and date-trees. We passed the night on the eastern bank of the Orinoco, at the foot of a granitic hill. Near this desert spot was formerly seated the Mission of San Regis. "We could have wished to find a spring in the Baraguan, for the water of the river had a smell of musk, and a sweetish taste ex- tremely disagreeable. In the Orinoco, as well as in the Apure, we are struck with the difference observable in the various parts of the river near the most barren shore. The water is sometimes very drinkable, and sometimes seems to be loaded with a slimy matter. " It is the bark (meaning the coriaceous covering) of the putrified cayman that is the cause," say the natives. " The more aged the cayman, the more Utter is his bark" I have no doubt that the carcasses of these large reptiles, those of the manatis, which weigh five hundred pounds, and the presence of the porpoises (toninas) with their mucilaginous skin, may contaminate the water, especially in the creeks, where the river has little velocity. Yet the spots where we found the most fetid water, were not always those where dead animals were accumulated on the beach. When, in such burning climates, where we are constantly tormented by thirst, we are reduced to drink the water of a river at the temperature of 27° or 28°, we cannot help wishing at least that water so hot, and so loaded with sand, should be free from smell. On the 8th of April we passed the mouths of the Suapure or Sivapuri, and the Caripo, on the east, and the outlet of the Sinaruco on the west. This last river is, next to the Rio Arauca, the most considerable between the Apure and the Meta. The Suapure, full of little cascades, is celebrated among the Indians for the quantity of wild honey obtained from the forests in its neighbourhood. The melipones there suspend their enormous hives to the branches of trees. Father Grili, in 1766, made an excursion on the Suapure, and on the Turiva, which falls into it. He there found tribes of the nation of Areverians. We passed the night a little below the island Macapina. Early on the following morning we arrived at the beach tf Pararuma, where we found an encampment of Indian^ YOUNG CROCODILES. 201 similar to that we had seen at the Boca de la Tortuga. They had assembled to search the sands, for collecting the turtles* eggs, and extracting the oil ; bat they had unfortu- nately made a mistake of several days. The young turtles had come out of their shells before the Indians had formed their camp ; and consequently the crocodiles and the garzes, a species of large white herons, availed themselves of the delay. These animals, alike fond of the flesh of the young turtles, devour an innumerable quantity. They fish during the night, for the tortuguillos do not come out of the earth to gain the neighbouring river till after the evening twilight. The zamuro vultures are too indolent to hunt after sunset. They stalk along the shores in the daytime, and alight in the midst of the Indian encampment to steal provisions; but they often find no other means of satisfying their voracity than by attacking young crocodiles of seven or eight inches long, either on land or in water of little depth. It is curious to see the address with which these little animals defend themselves for a time against the vultures. As soon as they perceive the enemy, they raise themselves on their fore paws, bend their backs, and lift up their heads, opening their wide jaws. They turn continually, though slowly, toward their assailant to show him their teeth, which, even when the animal has but recently issued from the egg, are very long and sharp. Often while the attention of a young crocodile is wholly engaged by one of the zamuros, another seizes the favourable opportunity for an unforeseen attack. He pounces on the crocodile, grasps him by the neck, and bears him off to the higher regions of the air. We had an opportunity of observing this manoeuvre during several mornings, at Mompex, on the banks of the Magdalena, where we had collected more than forty very young crocodiles, in a spacious court surrounded by a wall. We found among the Indians assembled at Pararuma some white men, who had come from Angostura to purchase the tortoise-butter. After having wearied us for a long time with their complaints of the 'bad harvest,' and the mischief done by the tigers among the turtles, at the time of laying their eggs, they conducted us beneath an ajoupa, that rose in the centre of the Indian camp. We tnere found the missionary-monks of Carichana and tvje 202 HUMiDirT or THE CLIMATE. Cataracts seated on the ground, playing at cards, and smoking tobacco in long pipes. Their ample blue garments, their shaven heads, and their long beards, might have led us to mistake them for natives of the East. These poor priests received us in the kindest manner, giving us every informa- tion necessary for the continuation of our voyage. They had suffered from tertian fever for some months ; and their pale and emaciated aspect easily convinced us that the countries we were about to visit were not without danger to the health of travellers. The Indian pilot, who had brought us from San Fernando de Apure as far as the shore of Pararuma, was unacquainted with the passage of the rapids* of the Orinoco, and would not undertake to conduct our bark any farther. We were obliged to conform to his will. Happily for us, the mis- sionary of Carichana consented to sell us a fine canoe at a very moderate price: and Father Bernardo Zea, missionary of the Atures and Maypures near the great cataracts, offered, though still unwell, to accompany us as far as the frontiers of Brazil. The number of natives who can assist in guiding boats through the Haudales is so inconsiderable that, but for the presence of the monk, we should have risked spending whole weeks in these humid and unhealthy regions. On the banks of the Orinoco, the forests of the Bio Negro are considered as delicious spots. The air is indeed cooler and more healthful. The river is free from crocodiles; one may bathe without apprehension, and by night as well as by day there is less torment from the sting of insects than on the Orinoco. Father Zea hoped to re- establish his health by visiting the Missions of Eio Negro. He talked of those places with that enthusiasm which is felt in all the colonies of South America for everything far off. The assemblage of Indians at Pararuma again excited in us that interest, which everywhere attaches man in a cultivated state to the study of man in a savage condition, and the successive development of his intellectual faculties. How difficult io recognize in this infancy of society, in this assemblage of dull, silent, inanimate Indians, the primitive character of our species ! Human nature does not here manifest those features of artless simplicity, of whicb * Little cascades (chorros raudalitoa). PIQMEXTS. 203 poets in every language have drawn such enchanting pictures. The savage of the Orinoco appeared to us to be as hideous as the savage of the Mississippi, described by that philosophical traveller Volney, who so well knew how to paint man in different climates. We are eager to persuade ourselves that these natives, crouching before the fire, or seated on large turtle-shells, their bodies covered with earth and grease, their eyes stupidly fixed for whole hours on the beverage they are preparing, far from being the primitive type of our species, are a degenerate race, the feeble remains of nations who, after having been long dispersed in the forests, are replunged into barbarism. Bed paint oeing in some sort the only clothing of the Indians, two kinds may be distinguished among them, according as they are more or less affluent. The common decoration of the Caribs, the Ottomacs, and the Jaruros, is onoto* called by the Spaniards achote, and by the planters of Cayenne, rocou. It is the colouring matter extracted from the pulp of the Bixa orellana.t The Indian women prepare the anaio by throwing the serds of the plant into a tub filled with water. They beat tnis water for an hour, and then leave h ro deposit the colouring fecula, which is of an intense brick-red. After having separated the water, they take out the fecula, dry it between their hands, knead it with oil of turtles' eggs, and form it into round cakes of three or four ounces weight. When turtle oil is wanting, some tribes mix with the anato the fat of the crocodile. Another pigment, much more valuable, is extracted from a plant of the family of the bignonise, which M. Bonpland has made known by the name of Bignonia chica. It climbs up and clings to the tallest trees by the aid of tendrils. Its bilabiate flowers are an inch long, of a fine violet colour, and disposed by twos or threes. The bipinnate leaves become reddish in drying. The fruit is a pod, filled with winged seeds, and is two feet long. This plant grows * Properly anoto. This word belongs to the Tamanac Indians. The Maypures call it majepa. The Spanish missionaries say onotarse, ' to rub the skin with anato.' t The word bixa, adopted by botanists, is derived from the ancie* language of Hayti (the island of St. Domingo). Rocou, the term com- nonly used by the French, is derived from the Brazilian word, tr*r«. 204 INDIAN PIGMENTS. spontaneously, and in great abundance, near Muypures fand in going up the Orinoco, beyond the mouth of the Ghia- viare, from Santa Barbara to the lofty mountain of Duida, particularly near Esmeralda. We also found it on the banks of the Cassiquiare. The red pigment of cJiica is not ob- tained from the fruit, like the onoto, but from the leaves macerated in water. The colouring matter separates in the form of a light powder. It is collected, without being mixed with turtle-oil, into little lumps eight or nine inches long, and from two to three high, rounded at the edges. These lumps, when heated, emit an agreeable smell of benzoin. When the chica is subjected to distillation, it yields no sensible traces of ammonia. It is not, like indigo, a sub- stance combined with azote. It dissolves slightly in sul- phuric and muriatic acids, and even in alkalis. Ground with oil, the chica furnishes a red colour that has a tint of lake. Applied to wool, it might be confounded with mad- der-red. There is no doubt but that the chica, unknown in Europe before our travels, may be employed usefully in the arts. The nations on the Orinoco, by whom this pigment is best prepared, are the Salivas, the Ghiipunaves,* the Caveres, and the Piraoas. The processes of infusion and maceration are in general very common among all the nations on the Orinoco. Thus the Maypures carry on a trade of barter with the little loaves of purtvma, which is a vegetable fecula, dried in the manner of indigo, and yield- ing a very permanent yellow colour. The chemistry of the savage is reduced to the preparation of pigments, that of poisons, and the dulcification of the amylaceous roots, which the aro'ides and the euphorbiaceous plants afford. Most of the missionaries of the tipper and Lower Ori- noco permit the Indians of their Missions to paint their skins. It is painful to add, that some of them speculate on this barbarous practice of the natives. In their huts, pompously called conventos,+ I have often seen stores of chica, which they sold as high as four francs the cake. To form a just idea of the extravagance of the decoration of these naked Indians, I must observe, that a man of large * Or Guaypuflaves ; they call themselves Uipunavi. f In the Missions, the priest's house bears the name of ' the con rent.' OHIO IN OF PAINTING THE SKIN. 205 stfiiure gains with difficulty enough by the labour of a forfc* night, to procure in exchange the chica necessary to paint himself red. Thus as we say, in temperate climates, of a poor man, "he has not enough to clothe himself," you hear the Indians of the Orinoco say, " that man is so poor, that he has not enough to paint half his body." The little trade in chica is carried on chiefly with the tribes of the Lower Orinoco, whose country does not produce the plant which furnishes this much-valued substance. The Caribs and the Ottomacs paint only the head and the hair with chica, but the Salives possess this pigment in sufficient abundance to cover their whole bodies. When the missionaries send on their own account small cargoes of cacao, tobacco, and chiquichiqui* from the Rio Negro to Angostura, they always add some cakes of chica, as being articles of merchandise in great request. The custom of painting is not equally ancient among all the tribes of the Orinoco. It has increased since the time when the powerful nation of the Caribs made frequent in- cursions into those countries. The victors and the van- quished were alike naked ; and to please the conqueror it was necessary to paint like him, and to assume his colour. The influence of the Caribs has now ceased, and they remain circumscribed between the rivers Carony, Cuyuni, and Paraguamuzi ; but the Caribbean fashion of painting the whole body is still preserved. The custom has sur- vived the conquest. Does the use of the anato and chica derive its origin from the desire of pleasing, and the taste for ornament, so common among the most savage nations ? or must we sup- pose it to be founded on the observation, that these colour- ing and oily matters with which the skin is plastered, preserve it from the sting of the mosquitos ? I have often heard this question discussed in Europe ; but in the Mis- sions of the Orinoco, and wherever, within the tropics, the air is filled with venomous insects, the inquiry would appear absurd. The Carib and the Salive, who are painted red, are not less cruelly tormented by the mosquitoa and the zancudos, than the Indians whose bodies are plastered with no colour. The sting of the insect causei * Ropes made with the petioles of a palm-ti \? ? ith pinnate leaves. 206 PLAGUE OF THTC MOSQtlTOS. no swelling in either; and scarcely ever produces those little pustules which occasion such smarting and itching to Europeans recently arrived. But the native and the "White suffer equally from the sting, till the insect has with- drawn its sucker from the skin. After a thousand useless essays, M. Bonpland and myself tried the expedient of rubbing our hands and arms with the fat of the crocodile, and the oil of turtle-eggs, but we never felt the least relief, and were stung as before. I know that the Lap- landers boast of oil and fat as the most useful preservatives ; but the insects of Scandinavia are not of the same species as those of the Orinoco. The smoke of tobacco drives away our gnats, while it is employed in vain against the zancudos. If the application of fat and astringent* sub- stances preserved the inhabitants of these countries from the torment of insects, as Father Grumilla alleges, why has not the custom of painting the skin become general on these shores? Why do so many naked natives paint only the face, though living in the neighbourhood of those who paint the whole bodypf We are struck with the observation, that the Indians of the Orinoco, like the natives of North America, prefer the substances that yield a red colour to every other. Is this predilection founded on the facility with which the savage procures ochreous earths, or the colouring fecula of anato and of chica ? I doubt this much. Indigo grows wild in a great part of equinoctial America. This plant, like so many other leguminous plants, would have furnished the natives abundantly with pigments to colour themselves blue like the ancient Britons.lt Yet we see no American tribe painted with indigo. It appears to me probable, as I have already hinted above, that the preference given by the Americans to the red colour is generally founded on the tendency which nations feel to attribute the idea of beauty to what- ever characterises their national physiognomy. Men whose skin is naturally of a brownish red, love a red colour.

If they be distinguished from other nations by a thin beard, they try to eradicate the few hairs that nature has given them. They think themselves embellished in proportion as thev heighten the characteristic marks of their race, or of their national conformation. We were surprised to *ee, that, in the camp of Pararuma, the women far advanced in years were more occupied with their ornaments than the youngest women. We saw an Indian female of the nation of the Ottomacs employing two of her daughters in the operation of rubbing her hair with the oil of turtles' eggs, and painting her back with anato and caruto. The ornament consisted of a sort of lattice- work formed of black lines crossing each other on a red ground. Each little square had a black dot in the centre. It was a work of incredible patience. We returned from a very long herborization, and the painting was not half finished. This research of ornament seems the more singu- lar when we reflect that the figures and marks are not produced by the process of tattooing, but that paintings executed with so much care are effaced,* if the Indian ex- poses himself imprudently to a heavy shower. There are some nations who paint only to celebrate festivals ; others are covered with colour during the whole year : and the latter consider the use of anato as so indispensable, that both men and women would perhaps be less ashamed to present themselves without a guayuco^ than destitute of paint. These guayucos of the Orinoco are partly bark of trees, and partly cotton-cloth. Those of the men are broader than those worn by the women, who, the missionaries say, have in general a less lively feeling of modesty. A similar ob- servation was made by Christopher Columbus.

When we speak in Europe of a native of Gruiana, we figure to ourselves a man whose head and waist are deco- rated with the fine feathers of the macaw, the toucan, and the humming-bird. Our painters and sculptors have long since /egarded these ornaments as the characteristic marks of an American. We were surprised at not finding in the Chayma Missions, in the encampments of Uruana and of Pararuma (I might almost say on all the shores of the Orinoco and the Cassiquiare) those fine plumes, those fea- thered aprons, which are so often brought by travellers from Cayenne and Demerara. These tribes for the most part, even those whose intellectual faculties are most ex- panded, who cultivate alimentary plants, and know how to weave cotton, are altogether as naked,* as poor, and as destitute of ornaments as the natives of New Holland. The excessive heat of the air, the profuse perspiration in which the body is bathed at every hour of the day and a great part of the night, render the use of clothes insupportable. Their objects of ornament, and particularly their plumes of fea- thers, are reserved for dances and solemn festivals. The plumes worn by the Gruipufiavest are the most celebrated ; being composed of the fine feathers of manakins and parrots. Tlie Indians are not always satisfied with one colour uniformly spread; they sometimes imitate, in the most whimsical manner, in painting their skin, the form of Euro- pean garments. We saw some at Pararuma, who were painted with blue jackets and black buttons. The mission- aries related to us that the Gruaynaves of the Eio Caura are accustomed to stain themselves red with anato, and to make broad transverse stripes on the body, on which they stick spangles of silvery mica.

PAINTED BODIES OF THE INDTAJfS. 200 naked men appear to be dressed in laced clothes. If painted nations had been examined with the same attention as those who are clothed, it would have been perceived that the most fertile imagination, and the most mutable caprice, have created the fashions of painting, as well as those oi garments. Painting and tattooing are not restrained, in either the New or the Old World, to one race or one zone only. These ornaments are most common among the Malays and Ame- rican races ; but in the time of the Romans they were also employed by the white race in the north of Europe. As the most picturesque garments and modes of dress are found in the Grecian Archipelago and western Asia, so the type of beauty in painting and tattooing is displayed by the islanders of the Pacific. Some clothed nations still paint their hands, their nails, and their faces. It would seem that painting is then confined to those parts of the body that remain uncovered; and while rouge, which recalls to mind the savage state of man, is disappearing by degrees in Europe, in some towns of the province of Peru the ladies think they embellish their delicate skins by covering them with colouring vegetable matter, starch, wnite-of-egg, and flour. After having lived a long time among men painted with anato and chica, we are singularly struck with these re- mains of ancient barbarism retained amidst all the usages of civilization. The encampment at Pararuma afforded us an opportunity of examining several animals in their natural state, which, till then, we had seen only in the collections of Europe. These little animals form a branch of commerce for the missionaries. They exchange tobacco, the resin called mani, the pigment of chica, gallitos (rock-manakins), orange mon- keys, capuchin monkeys, and other species of monkeys in great request on the coast, for cloth, nails, hatchets, fish- nook a, and pins. The productions of the Orinoco are bought at a low pnce from the Indians, who live in dependence on the monks; and these same Indians purchase ishing and gardening implements from the monks at a very high price, with the money they have gained at the egc-harvest. We ourselves bought several animals, which we kept with VOL. n. p 210 THE ROCK-MANAKIW. as throughout the rest of our passage on the river, and studied their manners. The gallitos, or rock-manakins, are sold at Pararuma in pretty little cages made of the footstalks of palm-leaves. These birds are infinitely more rare on the banks of the Ori- noco, and in the north and west of equinoctial America, than in French Guiana. They have hitherto been found only near the Mission of Encaramada, and in the Eaudales or cataracts of Maypures. I say expressly in the cataracts, because the gallitos choose for their habitual dwelling the hollows of the little granitic rocks that cross the Orinoco and form such numerous cascades. "We sometimes saw them appear in the morning in the midst of the foam of the river, calling their females, and fighting in the manner of our cocks, folding the double moveable crest that decorates the crown of the head. As the Indians very rarely take the full-grown gallitos, and those males only are valued in Europe, which from the third year have beautiful saffron-coloured plumage, purchasers should be on their guard not to confound young females with young males. Both the male and female gallitos are of an olive-brown; but the polio, or young male, is distinguishable at the earliest age, by its size and its yellow feet. After the third year the plumage of the males assumes a beautiful saffron tint; but the female remains always of a dull dusky brown colour, with yellow only on the wing-coverts and tips of the wings.* To preserve in our collections the fine tint of the plumage of a male and full-grown rock-manakin, it must not be exposed to the light. This tint grows pale more easy than in the other genera of the passerine order. The young males, as in most other birds, have the plumage or livery of their mother. 1 am surprised to see that so skilful a naturalist as Le Vaillant t can doubt whether the females always remain of a dusky olive tint. The Indians of the Eaudales all assured me that they had never seen a saffron-coloured female. Among the monkeys, brought by the Indians to the fair of Pararuma, we distinguished several varieties of the sai^ * Especially the part which ornithologists call the carpus. •f Oiseaux de Paradis, vol. ii, p. 61. J Simia capucina, (the capuchin monkey). BABE SPECIES OF MONJLEYS. 211 belonging to the little groups of creeping monkeys called matchi in the Spanish colonies ; marimcndes,* or ateles with a red belly ; titis, and viuditas. The last two species parti- cularly attracted our attention, and we purchased them to send to Europe. The titi of the Orinoco (Simia sciurea), well-known in our collections, is called bititeni by the Maypure Indians. It is very common on the south of the cataracts. Its face is white; and a little spot of bluish-black covers the mouth and the point of the nose. The titis of the most elegant form, and the most beautiful colour (with hair of a golden yellow), come from the banks of the Cassiquiare. Those that are taken on the shores of the Guaviare are large and difficult to tame. No other monkey has so much the phy- siognomy of a child as the titi ; there is the same expression of innocence, the same playful smile, the same rapidity in the transition from joy to sorrow. Its large eyes are instantly filled with tears, when it is seized with fear. It is ex- tremely fond of insects, particularly of spiders. The saga- city of this little animal is so great, that one of those we brought in our boat to Angostura distinguished perfectly the different plates annexed to Cuvier's 'Tableau elementaire d'Histoire naturelle.' The engravings of this work are not coloured ; yet the titi advanced rapidly its little hand in the hope of catching a grasshopper or a wasp, every time that we showed it the eleventh plate, on which these insects are represented. It remained perfectly indifferent when it was shown engravings of skeletons or heads of mammiferous animals.t When several of these little monkeys, shut up in the same cage, are exposed to the rain, and the habitual temperature of the air sinks suddenly two or three degrees, they twist their tail (which, however, is not pre- hensile) round their neck, and intertwine their arms and legs to warm one another. The Indian hunters told us, that * Simia belzebuth. f I may observe, that I have never heard of an instance in which a picture, representing, in the greatest perfection, hares or deer of their natural size, has made the least impression even on sporting dogs, the intelligence of which appears the most improved. Is there any authenticated instance of a dog having recognized a full length picture of his master ? In all these cases, the sight is not assisted by the smell. r 2 212 THE YIUDITA MONKEY. in the forests they often met groups of ten or twelve of these animals, whilst others sent forth lamentable cries, because they wished to enter amid the group to find warmth and shelter. By shooting arrows dipped in weak poison at one of these groups, a great number of young monkeys are taken alive at once. The titi in falling remains clinging to its mother, and if it be not wounded by the fall, it does not quit the shoulder or the neck of the dead animal. Most of those that are found alive in the huts of the Indians have been thus taken from the dead bodies of their mothers. Those that are full grown, when cured of a slight wound, commonly die before they can accustom themselves to a domestic state. The titis are in general delicate and timid little animals. It is very difficult to convey them from the Missions of the Orinoco* to the coast of Caracas, or of Cu- mana. They become melancholy and dejected in proportion as they quit the region of the forests, and enter the Llanos. This change cannot be attributed to the slight elevation of the temperature ; it seems rather to depend on a greater inten- sity of light, a less degree of humidity, and some chemical property of the air of the coast. The saimiri, or titi of the Orinoco, the atele, the sajou, and other quadrumanous animals long known in Europe, form a striking contrast, both in their gait and habits, with the macavahu, called by the missionaries viudita, or ' widow in mourning.' The hair of this little animal is soft, glossy, and of a fine black. Its face is covered with a mask of a square form and a whitish colour tinged with blue. This mask contains the eyes, nose, and mouth. The ears have a rim: they are small, very pretty, and almost bare. The neck of the widow presents in front a white band, an inch broad, and forming a semicircle. The feet, or rather the hinder hands, are black like the rest of the body ; but the fore paws are white without, and of a glossy black within. In these marks, or white spots, the missionaries think they recognize the veil, the neckerchief, and the gloves of a widow in mourning. The character of this little monkey, which sits up on its hinder extremities only when eating, is but little indicated in its appearance. It has a wild and timid air; it often refuses the food offered to it, even when tormented by a ravenous appetite. It has little inclination PREPARATIONS. 213 fur the society of other monkeys. The sight >f the smallest saiiniri puts it to flight. Its eye denotes great vivacity. We have seen it remain whole hours motionless without sleeping, and attentive to everything that was passing around. But this wildness and timidity are merely apparent. The viudita, when alone, and left to itself, becomes furious at the sight of a bird. It then climbs and runs with asto- nishing rapidity ; darts upon its prey like a cat ; and kills whatever it can seize. This rare and delicate monkey is found on the right bank of the Orinoco, in the granite moun- tains which rise behind the Mission of Santa Barbara. It inhabits also the banks of the Ghiaviare, near San Fernando de Atabapo. The viudita accompanied us on our whole voyage on the Cassiquiare and the E-io Negro, passing the cataracts twice. In studying the manners of animals, it is a great advantage to observe them during several months in the open air, and not in houses, where they lose all their natural vivacity. The new canoe intended for us was, like all Indian boats, a trunk of a tree hollowed out partly by the hatchet and partly by fire. It was forty feet long, and three broad. Three persons could not sit in it side by side. These canoes are so crank, and they require, from their instability, a cargo so equally distributed, that when you want to rise for an instant, you must warn the rowers to lean to the opposite side. Without this precaution the water would necessarily enter the side pressed down. It is difficult to form an idea of the inconveniences that are suffered in such wretched vessels. The missionary from the cataracts made the preparations for our voyage with greater energy than we wished. Lest there might not be a sufficient number of the Maco and Gua- hibe Indians, who are acquainted with the labyrinth of small channels and cascades of which the Raudales or cataracts are composed, two Indians were, during the night, placed in the cepo — a sort of stocks in which they were made to lie with their legs between two pieces of wood, notched and fastened together by a chain with a padlock. Early in the morning we were awakened by the cries of a young man, mercilessly beaten with a whip of manati skin. His name waa Zerepe, a very intelligent young Indian, who proved 214 SEVERE RULE OF THE MISSION AEIE8. highly useful to us in the sequel, but who now refused to accompany us. He was born in the Mission of Atures ; but his father was a Maco, and his mother a native of the nation of the Maypures. He had returned to the woods (al monte), and having lived some years with the unsubdued Indians, he had thus acquired the knowledge of several languages, and the missionary employed him as an inter- preter. We obtained with difficulty the pardon of this young man. " Without these acts of severity," we were told, ** you would want for everything. The Indians of the ftaudales and the Upper Orinoco are a stronger and more laborious race than the inhabitants of the Lower Orinoco. They know that they are much sought after at Angostura. If left to their own will, they would all go down the river to sell their productions, and live in full liberty among the whites. The Missions would be totally deserted." These reasons, I confess, appeared to me more specious than sound. Man, in order to enjoy the advantages of a social state, must no doubt sacrifice a part of his natural rights, and his original independence ; but, if the sacrifice imposed on him be not compensated by the benefits of civi- lization, the savage, wise in his simplicity, retains the wish of returning to the forests that gave him birth. It is because the Indian of the woods is treated like a person in a state of villanage in the greater part of the Missions, because he enjoys not the fruit of his labours, that the Christian esta- blishments on the Orinoco remain deserts. A government founded on the ruins of the liberty of the natives extin- guishes the intellectual faculties, or stops their progress. To say that the savage, like the child, can be governed only by force, is merely to establish false analogies. The Indians of the Orinoco have something infantine in the expression of their joy, and the quick succession of their emotions, but they are not great children ; they are as little so as the poor labourers in the east of Europe, whom the barbarism of our feudal institutions has held in the rudest state. To consider the employment of force as the first ana sole means of the civilization of the savage, is a principle as far from being true in the education of nations as in the education of youth. Whatever may be the state of weak- ness or degradation in our species, no faculty is entirely ACCOMMODATION ON BOARD. 215 annihilated. The human understanding exhibits only dif- ferent degrees of strength and development. The savage, like the child, compares the present with the past; he directs his actions, not according to blind instinct, but motives of interest. Reason can everywhere enlighten reason ; and its progress will be retarded in proportion as the men who are called upon to bring up youth, or govern nations, substitute constraint and force for that moral influence which can alone unfold the rising faculties, calm the irritated passions, and give stability to social order. We could not set sail before ten on the morning of the 10th. To gain something in breadth in our new canoe, a sort of lattice-work had been constructed on the stern with branches of trees, that extended on each side beyond the gunwale. Unfortunately, the toldo or roof of leaves, that covered this lattice-work, was so low that we were obliged to lie down, without seeing anything, or, if seated, to sit nearly double. The necessity of carrying the canoe across the rapids, and even from one river to another ; and the fear of giving too much hold to the wind, by making the toldo higher, render this construction necessary for vessels that go up towards the Bio Negro. The toldo was intended to cover four persons, lying on the deck or lattice-work of brush-wood ; but our legs reached far beyond it, and when it rained half our bodies were wet. Our couches consisted of ox-hides or tiger-skins, spread upon brandies of trees, which were painfully felt through so thin a covering. The fore part of the boat was filled with Indian rowers, furnished with paddles, three feet long, in the form of spoons. They were all naked, seated two by two, and they kept time in rowing with a surprising uniformity, singing songs of a sad and monotonous character. The small cages contain- ing our birds and our monkeys, the number of which aug- mented as we advanced, were hung some to the toldo and others to the bow of the boat. This was our travelling menagerie. Notwithstanding the frequent losses occasioned by accidents, and above all by the fatal effects of exposure to the sun, we had fourteen of these little animals alive at our return from the Cassiquiare. Naturalists, who wish to collect and bring living animals to Europe, might cause to bo constructed expressly for this purpose at Ango» 210 UNCOMFORTABLE AEEANGEMENTS. tura, or at Grand Para, the two capitals situated on the banks of the Orinoco and the Amazon, the fore-deck oi which boats might be fitted up with two rows of cages shel- tered from the rays of the sun. Every night, when we esta- blished our watch, our collection of animals and our instru- ments occupied the centre ; around these were placed first our hammocks, then the hammocks of the Indians ; and on the outside were the fires which are thought indispensable against the attacks of the jaguar. About sunrise the mon- keys in our cages answered the cries of the monkeys of the forest. These communications between animals of the same species sympathizing with one another, though unseen, one party enjoying that liberty which the other regrets, have something melancholy and affecting. In a canoe not three feet wide, and so incumbered, there remained no other place for the dried plants, trunks, a sextant, a dipping-needle, and the meteorological instru- ments, than the space below the lattice-work of branches, on which we were compelled to remain stretched the greater part of the day. If we wished to take the least object out of a trunk, or to use an instrument, it was necessary to row ashore and land. To these inconveniences were joined the torment of the mosquitos which swarmed under the toldo, and the heat radiated from the leaves of the palm- trees, the upper surface of which was continually exposed to the solar rays. We attempted every instant, but always without success, to amend our situation. While one of us hid himself under a sheet to ward off the insects, the other insisted on having green wood lighted beneath the toldo, in the hope of driving away the mosquitos by the smoke. The iminful sensations of the eyes, and the increase of heat, already stifling, rendered both these contrivances alike im- Dracticable. With some gaiety of temper, with feelings of mutual good-will, and with a vivid taste for the majestic grandeur of these vast valleys of rivers, travellers easily support evils that become habitual. Our Indians showed us, on the right bank of the river, the place which was formerly the site of the Mission of Pararuma, founded by the Jesuits about the year 1733. The mortality occasioned by the small-pox among the Salive Indians was the principal cause of the dissolution of the PHENOMENA OF HAILSTORMS. 217 ^* <&ivit' the Andes. The megatherium inhabited the plains of Uruguay. On digging deep into the ground, in high valleys, where neither palm-trees nor arborescent ferns can grow, strata of coal are discovered, that still show vestiges of gigantic monocotyledonous plants. There was a remote period then, in which the classes of plants were otherwise distributed, when the animals were larger, and the rivers broader aud of .greater depth. There TOL. II. < 226 MYSTERIOUS SOUND? end th )se records of nature, that it is in our power to con- sult. "We are ignorant whether the human race, which at the time of the discovery of America scarcely formed a few feeble tribes on the east of the Cordilleras, had already descended into the plains ; or whether the ancient tradition of the ' great waters,' which is found among the nations of the Orinoco, the Erevato, and the Caura, belong to other climates, whence it has been propagated to this part of the New Continent. On the llth of April, we left Carichana at two in the afternoon, and found the course of the river more and more encumbered by blocks of granite rocks. "We passed on the west the Cano Orupe, and then the great rock known by the name of Piedra del Tigre. The river is there so deep, that no bottom can be found with a line of twenty-two fathoms. Towards evening the weather became cloudy and gloomy. The proximity of the storm was marked by squalls alternating with dead calms. The rain was violent, and the roof of foliage, under which we lay, afforded but little shelter. Happily these showers drove away the mos- quitos, at least for some time. "We found ourselves before the cataract of Cariven, and the impulse of the waters was so strong, that we had great difficulty in gaining the land. "We were continually driven back to the middle of the cur- rent. At length two Salive Indians, excellent swimmers, leaped into the water, and having drawn the boat to shore by means of a rope, made it fast to the Piedra de Carichana Vieja, a shelf of bare rock, on which we passed the night. The thunder continued to roll during a part of the night ; the swell of the river became considerable ; and we were several times afraid that our frail bark would be driven from the shore by the impetuosity of the waves. The granitic rock on which we lay is one of those, where travellers on the Orinoco have heard from time to time, towards sunrise, subterraneous sounds, resembling those of the organ. The missionaries call these stones laxas de musica. ' It is witchcraft (cosa de bruxas),' said our young Indian pilot, who could speak Spanish. "We never our- selves heard these mysterious sounds, either at Carichana Vieia, or in the Upper Orinoco ; but from information given us by witnesses worthy of belief, the existence of a pheno- THE STATUE OF MEMNOff. 227 menor that seems to depend on a certain state of the atmosphere, cannot be denied. The shelves of rock are full of very narrow and deep crevices. They are heated during the day to 48° or 50°. I several times found their tempe- rature at the surface, during the night, at 39°, the surround- ing atmosphere being at 28°. It may easily be conceived, that the difference of temperature between the subterranean and the external air attains its maximum about sunrise, or at that moment which is at the same time farthest from the period of the maximum of the heat of the preced- ing day. May not these organ-like sounds, which are heard when a person lays his ear in contact with the stone, be the effect of a current of air that issues out through the crevices ? Does not the impulse of the air against the elastic spangles of mica that intercept the crevices, contribute to modify the sounds? May we not abmit that the ancient inhabitants of Egypt, in passing incessantly up and down the Nile, had made the same observation on some rock of the Thebaid ; and that the ' music of the rocks' there led to the jugglery of the priests in the statue of Memnon ? Perhaps, when ' the rosy- fingered Aurora rendered her son, the glorious Memnon, vocal,'* the voice was that of a man hidden beneath the pedestal of the statue ; but the observation of the natives of the Orinoco, which we relate, seems to explain in a natural manner what gave rise to the Egyptian belief of a stone that poured forth rounds at sunrise. Almost at the same period at which I communicated these conjectures to some of the learned of Europe, three French travellers, MM. Jomard, Jollois, and Devilliers, were led to analogous ideas. They heard, at sunrise, in a monument of granite, at the centre of the spot on which stands the palace of Karnak, a noise resembling that of a string break- ing. Now this comparison is precisely that which the ancients employed in speaking of the voice of Memnon. The French travellers thought, like me, that the passage of * These are the words of an inscription, which attests that sounds were heard on the 13th of the month Pachon, in the tenth year of the reign of Antoninus. See Mooumenta de 1'Egypte Ancienne. 228 BATJDAL DE CARIYEff. rarefied air through the fissures of a sonorous stone might have suggested to the Egyptian priests the invention of the juggleries of the Memnonium. We left the rock at four in the morning. The mission- ary had told us that we should have great difficulty in passing the rapids and the mouth of the Meta. The Indians rowed twelve hours and a half without intermission, and during all that time, they took no other nourishment than cassava and plantains. When we consider the difficulty of overcoming the force of the current, and of passing the cataracts ; when we reflect on the constant employment of the muscular powers during a navigation of two months ; we are equally surprised at the constitutional vigour and the abstinence of the Indians of the Orinoco and the Amazon. Amylaceous and saccharine substances, some- times fish and the fat of turtles' eggs, supply the place of food drawn from the first two classes of the animal king- dom, those of quadrupeds and birds. We found the bed of the river, to the length of six hun- dred toises, full of granite rocks. Here is what is called the Maudal de Cariven. We passed through channels that were not five feet broad. Our canoe was sometimes jammed between two blocks of granite. We sought to avoid these Passages, into which the waters rushed with a fearful noise ; ut there is really little danger, in a canoe steered by a good Indian pilot. When the current is too violent to be resisted the rowers leap into the water, and fasten a rope to the point of a rock, to warp the boat along. This manoeuvre is very tedious ; and we sometimes availed ourselves of it, to climb the rocks among which we were entangled. They are of all dimensions, rounded, very black, glossy like lead, and destitute of vegetation. It is an extraordinary phenomenon to see the waters of one of the largest rivers on the globe in some sort disappear. We perceived, even far from the shore those immense blocks of granite, rising from the ground and leaning one against another. The intervening channels in the rapids are more than twenty-five fathoms deep ; anc are the more difficult to be observed, as the rocks are oftei . narrow toward their bases, and form vaults suspended ove • tl 3 surface of the river. We perceived no crocodiles in ths raudal; these animals seem to shun the noise of cataracts. THE RIO METJL. 229 From Cabruta to the mouth of the Kio Sinaruco, a distance of nearly two degrees of latitude, the left bank of the Orinoco is entirely uninhabited; but to the west of the Randal de Cariven an enterprising man, Don Felix Relinchon, had assembled some Jaruro and Ottomac Indiana in a small village. It is an attempt at civilization, on which the monks have had no direct influence. It is superfluous to add, that Don Felix lives at open war with the mis- sionaries on the right bank of the Orinoco. Proceeding up the river we arrived, at nine in the morning, before the mouth of the Meta, opposite the spot where the Mission of Santa Teresa, founded by the Jesuits, was here- tofore situated. Next to the Guaviare, the Meta is the most considerable river that flows into the Orinoco. It may be compared to the Danube, not for the length of its course, but for the volume of its waters. Its mean depth is thirty-six feet, and it sometimes reaches eighty-four. The union of these two rivers presents a very impressive spectacle. Lonely rocks rise on the eastern bank. Blocks of granite, piled upon one another, appear from afar like castles in ruins, vast sandy shores keep the skirting of the forest at a distance from the river ; but we discover amid them, in the horizon, solitary palm-trees, backed by the sky, and crowning the tops of the mountains. "We passed two hours on a large rock, standing in the middle of the Orinoco, and called the Piedra de la Pacien^ia, or the Stone of Patience, because the canoes, in going up, are sometimes detained there two days, to extricate themselves from the whirlpool caused by this rock. The Kio Meta, which traverses the vast plains of Casa- nare, and which is navigable as far as the foot of the Andes of New Grenada, will one day be of great political import- ance to the inhabitants of Guiana and Venezuela. From the Golfo Triste and the Boca del Drago a small fleet may go up the Orinoco and the Meta to within fifteen or twenty leagues of Santa Fe de Bogota. The flour of New Grenada may be conveyed the same way. The Meta is like a canal of communication between countries placed in tho same latitude, but differing in their productions as much as France and Senegal. The Meta has its source in the union 230 NAVIGATION OF THE EITEE. of two rivers which descend from the paramos of Chingasa and Suma Paz. The first is the Bio Negro, which, lower down, receives the Pachaquiaro ; the second is the Bio de Aguas Blancas, or Umadea. The junction takes place near the port of Marayal. It is only eight or ten leagues from the Passo de la Cabulla, where you quit the Eio Negro, to the capital of Santa Fe. Prom the villages of Xiramena and Cabullaro to those of Guanapalo and Santa Rosalia de Cabapuna, a distance of sixty leagues, the banks of the Meta are more inhabited than those of the Orinoco. "We find in this space fourteen Christian settle- ments, in part very populous ; but from the mouths of the rivers Pauto and Casanare, for a space of more than fifty leagues, the Meta is infested by the Guahibos, a race of savages.* The navigation of this river was much more active in the time of the Jesuits, and particularly during the expedition of Iturriaga, in 1756, than it is at present. Missionaries of the same order then governed the banks of the Meta and of the Orinoco. The villages of Macuco, Zurimena, and Casi- mena, were founded by the Jesuits, as well as those of Uruana, Encaramada, and Carichana. These Fathers had conceived the project of forming a series of Missions from the junction of the Casanare with the Meta to that of the Meta with the Orinoco. A narrow zone of cultivated land would have crossed the vast steppes that separate the forests of Guiana from the Andes of jNew Grenada. At the period of the "harvest of turtles' eggs," not only the flour of Santa Fe descended the river, but the salt of Chita,f the cotton cloth of San Gil, and the printed coun- terpanes of Socorro. To give some security to the little traders who devoted themselves to this inland commerce, attacks were made from time to time from the castillo or fort of Carichana, on the Guahibos. To keep these Guahibos in awe, the Capuchin mission- aries, who succeeded the Jesuits in the government of the * I find the word written Guajilos, Guahivos, and Guagivos.

BAFTS OF THE NATITKS. 231 Missions of the Orinoco, formed the project of founding a city at the mouth of the Meta, under the name of the Villa de San Carlos. Indolence, and the dread of tertian fevers, have prevented the execution of this project ; and all that has ever existed of the city of San Carlos,' is a coat of arms painted on fine parchment, with an enormous cross erected on the bank of the Meta. The Guahibos, who, it is said, are some thousands in number, have become so insolent, that, at the time of our passage by Carichana, they sent word to the missionary that they would come on rafts, and burn his village. These rafts (valzas), which we had an opportunity of seeing, are scarcely three feet broad, and twelve feet long. They carry only two or three Indians ; but fifteen or sixteen of these rafts are fastened to each other with the stems of the paullinia, the dolichos, and other creeping plants. It is difficult to conceive how these small craft remain tied together in passing the rapids. Many fugitives from the villages of the Casanare and the Apure have joined the Guahibos, and taught them the practice of eating beef, and preparing hides. The farms of San Vicente, Kubio, and San Antonio, have lost great numbers of their horned cattle by the incursions of the Indians, who also prevent travellers, as far as the junction of the Casanare, from sleeping on the shore in going up the Meta. It often happens, while the waters are low, that the traders of New Grenada, some of whom still visit the encampment of Para- ruma, are killed by the poisoned arrows of the Guahibos. From the mouth of the Meta, the Orinoco appeared to us to be freer of shoals and rocks. We navigated in a channel five hundred toises broad. The Indians remained rowing m the boat, without towing or pushing it forward with the^ arms, and wearying us with their wild cries. We passo^ the Can os of Uita and Endava on the west. It was night when we reached the Randal de Tabaje. The Indians would not hazard passing the cataract; and we slept on a very incommodious spot, on the shelf* of a rock, with a slope of more than eighteen degrees, and of which the crevices sheltered a swarm of bats. We heard the cries of the jaguar very near us during the whole night. They were answered by our great dog in lengthened bowlings. I waited the appearance of the stars in vain: the sky waa 232 ASPECT OF THE ITTDTANS." exceedingly black ; and the hoarse sounds of the cascades of the Orinoco mingled with the rolling of the distant thunder. Early in the morning of the 13th April we passed the rapids of Tabaje, and again disembarked. Father Zea, who accompanied us, desired to perform mass in the new Mission of San Borja, established two years before. "We there found six houses inhabited by uncatechised Gruahibos. They differ in nothing from the wild Indians. Their eyes, which are jarge and black, have more vivacity than those of the Indians who inhabit the ancient missions. We in vain offered them brandy ; they would not even taste it. The faces of all the young girls were marked with round black spots ; like the patches by which the ladies of Europe formerly imagined they set off the whiteness of their skins. The bodies of the G-uahibos were not painted. Several of them had beards, of which they seemed proud; and, taking us by the chin, showed us by signs, that they were made like us. Their shape was in general slender. I was again struck, as I had been among the Salives and the Macos, with the little uniformity of features to be found among the Indians of the Orinoco. Their look is sad and gloomy ; but neither stern nor ferocious. Without having any notion of the practices of the Christian religion, they behaved with the utmost decency at church. The Indians love to exhibit themselves ; and will submit temporarily to any restraint or subjection, provided they are sure of drawing attention. At the moment of the consecration, they made signs to one another, to indicate beforehand that the priest was going to raise the chalice to his lips. With the exception of this gesture, they remained motionless and in imperturbable apathy. The interest with which we examined these poor savages became perhaps the cause of the destruction of the mission. Some among them, who preferred a wandering life to the labours of agriculture, persuaded the rest to return to the plains of the Meta. They told them, " that the white men would come back to San Borja, to take them away in the boats, and sell them as poitos, or slaves, at Angostura." The Gruahibos awaited the news of our return from the Rio Negro by the Cassiquiare; and when they heard that we were arrived at the first great cataract, that of Atures, they all deserted, and fled to the savannahs that border the THEIR DISGCJSTING VORVCITT. 233 Orinoco on the vest. The Jesuit Fathers had already formed a mission on this spot, and bearing the same name. No tribe is more difficult to fix to the soil than the Gua- hibos. They would rather feed on stale fish, scolopendras, and worms, than cultivate a little spot of ground. The other Indians say, that "a Guahibo eats everything that exists, both on and under the ground." In ascending the Orinoco more to the south, the heat, far from increasing, became more bearable. The air in the day was at 26° or 27'5° ; and at night, at 237°. The water of the Orinoco retained its habitual temperature of 27*7°. The torment of the mosquitos augmented severely, notwithstand- ing the decrease of heat. We never suffered so much from them as at San Borja. We could neither speak nor uncover our faces without having our mouths and noses filled with insects. We were surprised not to find the thermometer at 35° or 36° ; the extreme irritation of the skin made ua believe that the air was scorching. We passed the night on the beach of Guaripo. The fear of the little caribe fish prevented us from bathing. The crocodiles we had met with this day were all of an extraordinary size, from twenty- two to twenty-four feet. Our sufferings from the zancudos made us depart at five o'clock on the morning of the 14th. There are fewer insects in the strata of air lying immediately on the river, than near the edge of the forests. We stopped to breakfast at the island of Guachaco, or Vachaco, where the granite is immediately covered by a formation of sandstone, or con- glomerate. This sandstone contains fragments of quartz, and even of feldspar, cemented by indurated clay. It exhi- bits little veins of brown iron-ore, which separate in laminae, or plates, of one line in thickness. We had already found these plates on the shores between Encaramada and Bara- guan, where the missionaries had sometimes taken them for an ore of gold, and sometimes for tin. It is probable, that this secondary formation occupied formerly a larger space. Having passed the mouth of the Rio Parueni, beyond which the Maco Indians dwell, we spent the night on the island of Panumana. I could with difficulty take the altitudes of Can opus, in order to fix the longitude of the point, near which the river suddenly turns towards the west. The 234 BAPLDS OF THE ATTJHES. island of Panuinana is rich in plants. "We there again found those shelves of bare rock, those tufts of melastomas, those thickets of small shrubs, the blended scenery of which had charmed us in the plains of Carichana. The mountains of the Great Cataracts bounded the horizon towards the south-east. In proportion as we advanced, the shores of the Orinoco exhibited a more imposing and picturesque aspect. CHAPTER The Mouth of the Rio Anaveni. — Peak of Uniana. — Mission of Atures. — Cataract, or Raudal of Mapara. — Islets of Surupamana and Uirapuri. THE river of the Orinoco, in running from south to north, is crossed by a chain of granitic mountains. Twice confined in its course, it turbulently breaks on the rocks, that form steps and transverse dykes. Nothing can be grander than the aspect of this spot. Neither the fall of the Tequendama, near Santa Fe de Bogota, nor the magnificent scenes of the Cordilleras, could weaken the impression produced upon my mind by the first view of the rapids of Atures and of Maypures. When the spectator is so stationed that the eye can at once take in the long succession of cataracts, the immense sheet of foam and vapours illumined by the rays of the setting sun, the whole river seeins as it were sus- pended over its bed. Scenes so astonishing must for ages have fixed the atten- tion of the inhabitants of the New World. When Diego de Todaz, Alfonzo de Herrera, and the intrepid Ealeigh, an- chored at the mouth of the Orinoco, they were informed by the Indians of the Great Cataracts, which they them- selves had never visited, and which they even confounded with cascades farther to the east. Whatever obstacles the force of vegetation under the torrid zone may throw in the way of intercourse among nations, all that relates to the course of great rivers acquires a celebrity which extends to vast distances. The Orinoco, the Amazon, and the Tin* guay, traverse, like inland arms of seas, in different direr-* tions, a land covered with forests, and inhabited by tribf 3 DISSEMINATION OF IDEAS. 235 part of whom are cannibals. It is not yet two hundred years since civilization and the light of a more humane religion have pursued their way along the banks of these ancient canals traced by the hand of nature ; long, however, before the introduction of agriculture, before communica- tions for the purposes of barter were established among these scattered and often hostile tribes, the knowledge of extraordinary phenomena, of falls of water, of volcanic fires, and of snows resisting all the ardent heat of summer, was propagated by a thousand fortuitous circumstances. Three hundred leagues from the coast, in the centre of South America, among nations whose excursions do not extend to three days' journey, we find an idea of the ocean, and words that denote a mass of salt water extending as far as the eye can discern. Various events, which repeatedly occur in savage life, contribute to enlarge these conceptions. In consequence of the petty wars between neighbouring tribes, a prisoner is brought into a strange country, and treated as a poito or mero, that is to say, as a slave. After being often sold, he is dragged to new wars, escapes, and returns home ; he relates what he has seen, and what he has heard from those whose tongue he has been compelled to learn. As on discovering a coast, we hear of great inland animals, so, on entering the valley of a vast river, we are surprised to find that savages, who are strangers to navigation, have acquired a knowledge of distant things. In the infant state of society, the exchange of ideas precedes, to a certain point, the exchange of productions. The two great cataracts of the Orinoco, the celebrity of which is so far-spread and so ancient, are formed by the passage of the river across the mountains of Parima. They are called by the natives Mapara and Quittuna; but the missionaries have substituted for these names those of Atures and Maypures, after the names of the tribes which were first assembled together in the nearest villages. On the coast of Caracas, the two Great Cataracts are denoted by the simple appellation of the two Raudales, or rapids ; a denomination which implies that the other falls of water, even the rapids of Camiseta and of Carichana, are not con- sidered as worthy of attention when compared with the cataracts of Atures and Maypures. 236 FABULOUS LEGENDS. These last, situated between five and six degrees of north latitude, and a hundred leagues west of the Cordilleras of New Grenada, in the meridian of Porto Cabello, are only twelve leagues distant from each other. It is surprising lhat their existence was not known to D'Anville, who, in his fine map of South America, marks the inconsiderable cascades of Marimara and San Borja, by the names of the rapids of Carichana and Tabaje. The Great Cataracts divide the Christian establishments of Spanish Guiana into two unequal parts. Those situated between the Randal of Atures and the mouth of the river are called the Missions of the Lower Orinoco ; the Missions of the Upper Orinoco comprehend the villages between the Randal oi Maypures and the mountains of Duida. The course of the Lower Orinoco, if we estimate "the sinuosities at one-third of the distance in a direct line, is two hundred and sixty nautical leagues: the course of the Upper Orinoco, supposing ita sources to be three degrees east of Duida, includes one hun- dred and sixty-seven leagues. Beyond the Great Cataracts an unknown land begins. The country is partly mountainous and partly flat, receiving at once the confluents of the Amazon and the Orinoco. From the facility of its communications with the Bio Negro and Grand Para, it appears to belong still more to Brazil than to the Spanish colonies. None of the missionaries who have described the Orinoco before me, neither Father Gumilla, Gili, nor Caulin, had passed the Raudal of May- pures. We found but three Christian establishments above the Great Cataracts, along the shores of the Orinoco, in an extent of more than a hundred leagues; and these three establishments contained scarcely six or eight white persons, that is to say, persons of European race. We cannot be surprised that such a desert region should have been at all times the land of fable and fairy visions. There, accord- ing to the statements of certain missionaries, are found races of men, some of whom have an eye in the centre of the forehead, whilst others have dogs' heads, and mouths below their stomachs. There they pretend to have found all that the ancients relate of the Garamantes, of the Ari- maspes, and of the Hyperboreans. It would be an error to suppose that these simple and often rustic missioDariea ISLAND OF PANUMANA. 237 had themselves invented all these exaggerated fictions ; the}' derived them in great part from the recitals of the Indians. A fondness for narration prevails in the Missions, as it does at sea, in the East, and in every place where the mind seeks amusement. A missionary, from his vocation, is not inclined to scepticism; he imprints on his memory what the natives have so often repeated to him ; and, when returned to Europe, and restored to the civilized world, he finds a pleasure in creating astonishment by a recital of facts which he thinks he has collected, and by an animated description of remote things. These stories, which the Spanish colonists call 'tales of travellers and of monks' (cuentos de viageros y frailes), increase in improbability in proportion as you increase your distance from the forests of the Orinoco, and approach the coasts inhabited by the whites. "When, at Cumana, JSTueva Barcelona, and other seaports which have frequent communication with the Mis- sions, you betray any sign of incredulity, you are reduced to silence by these few words : " The fathers have seen it, but far above the Great Cataracts (mas arriba de los Kau» dales)." On the 15th of April, we left the island of Panumana at four in the morning, two hours before sunrise. The sky was in great part obscured, and lightnings flashed over dense clouds at more than forty degrees of elevation. "We were surprised at not hearing thunder; but possibly this was owing to the prodigious height of the storm ? It appears to us, that in Europe the electric flashes without thunder, vaguely called heat-lightning, are seen generally nearer the horizon. Under a cloudy sky, that sent back the radiant caloric of the soil, the heat was stifling; not a breath oi wind agitated the foliage of the trees. The jaguars, as usual, had crossed the arm of the Orinoco by which we were separated from the shore, and we heard their cries extremely near. During the night the Indians had advised us to quit our station in the open air, and retire to a deserted hut belonging to the conucos of the inhabitants of Atures. They had taken care to barricade the opening with planks, a precaution which seemed to us superfluous; but near the Cataracts tigers are very numerous, and two years before, in these very conucos of Panuinaua, an Indian returning to 238 SAN JUAN DE LOS ATURES. his hut, towards the close of the rainy season, found a tigress settled in it with her two young. These animals had inha- bited the dwelling for several months ; they wrere dislodged from it with difficulty, and it was only after an obstinate combat that the former master regained possession of his dwelling. The jaguars are fond of retiring to deserted ruins, and I believe it is more prudent in general for a solitary traveller to encamp in the open air, between two fires, than to seek shelter in uninhabited huts. On quitting the island of Panumana, we perceived on the western bank of the river the fires of an encampment of G-uahibo savages. The missionary who accompanied us caused a few musket-shots to be fired in the air, which he said would intimidate them, and shew that we were in a state to defend ourselves. The savages most likely had no canoes, and were not desirous of troubling us in the middle of the river. We passed at sunrise the mouth of the Rio Anaveni, which descends from the eastern mountains. On its banks, now deserted, Father Olmos had established, in the time of the Jesuits, a small village of Japuins or Jaru- ros. The heat was so excessive that we rested a long time in a woody spot, to fish with a hook and line, and it was not without some trouble that we carried away all the fish we had caught. We did not arrive till very late at the foot of the Great Cataract, in a bay called the lower harbour (puerto de abaxo) ; and we followed, not without difficulty, in a dark night, the narrow path that leads to the Mission of Atures, a league distant from the river. "We crossed a plain covered with large blocks of granite. The little village of San Juan Nepomuceno de los Atures was founded by the Jesuit Francisco Gronzales, in 1748. In going up the river this is the last of the Christian mis- sions that owe their origin to the order of St. Ignatius. The more southern establishments, those of Atabapo, of Cassiquiare, and of Bio Negro, were formed by the fathers of the Observance of St. Francis. The Orinoco appears to have flowed heretofore where the village of Atures now stands, and the flat savannah that surrounds the village no doubt formed part of the river. I saw to the east of the mission a succession of rocks, which seemed to have been the ancient shor? of the Orinoco. In the lapse of ages the STATE OF T1IE MISSION. 239 river has been impelled westward, in consequence of the accumulations of earth, which occur more frequently on the side of the eastern mountains, that are furrowed by torrents. The cataract bears the name of Mapara,* as we have men- tioned above ; while the name of the village is derived from that of the nation of Atures, now believed to be extinct. I find on the maps of the seventeenth century, Island and Cataract of Athule ; which is the word Atures written ac- cording to the pronunciation of the Tamanacs, who con- found, like so many other people, the consonants I and r. This mountainous region was so little known in Europe, even in the middle of the eighteenth century, that D' Anvilie, in the first edition of his South America, makes a branch issue from the Orinoco, near Salto de los Atures, and fall into the Amazon, to which branch he gives the name of Rio Negro. Early maps, as well as Father Gumilla's work, place the Mission in latitude 1° 30'. Abbe Grili gives it 3* 50'. I found, by meridian altitudes of Canopus and a of the' Southern Cross, 5° 38' 4" for the latitude ; and by the chro- nometer 4h 41' 17" of longitude west of the meridian of Paris. "We found this small Mission in the most deplorable state. It contained, even at the time of the expedition of Solano, commonly called the 'expedition of the boundaries,' three hundred and twenty Indians. This number had diminished, at the time of our passage by the Cataracts, to forty-seven ; and the missionary assured us that this diminution became from year to year more sensible. He showed us, that in the * I am ignorant of the etymology of this wor d, which I believe means only a fall of water. Gili translates into Maypure a small cascade (raudalilo) by uccamatisi mapara canacapatirri. Should we not spell this word matpara ? mat being a radical of the Maypure tongue, and meaning bad (Hervas, Saygio, N. 29). The radical par (para) is found among American tribes more than five hundred leagues distant from each other, the Caribs, Maypures, Brazilians, and Peruvians, in the words sea, rain, water, lake. We must not confound mapara with mapaja ; this last word signifies, in Maypure and Tamanac, the papaw or melon- tree, no doubt on account of the sweetness of its fruit, for mapa means in the Maypur », as well as in the Peruvian and Omagua tongues, ' the honej of bees.' The Tamanacs call a cascade, or raudal, in general uatapurutpe the Maypures, uca. 210 ANALOGY OF LANGUAGES. space of thirty-two months only one marriage had been entered in the registers of the parish church. Two others had been contracted by uncatechised natives, and celebrated before the Indian Gobernador. At the first foundation of the Mission, the Atures, Maypures, Meyepures, Abanis, and Quirupas, had been assembled together. Instead of these tribes we found only Guahibos, and a few families of the nation of Macos. The Atures have almost entirely disap- peared ; they are no longer known, except by the tombs in the cavern of Ataruipe, which recall to mind the sepulchres of the Gruanches at Teneriffe. We learned on the spot, that the Atures, as well as the Quaquas, and the Macos or Piaroas, belong to the great stock of the Salive nations ; while the Maypures, the Abanis, the Parenis, and the Guay- punaves, are of the same race as the Cabres or Caveres, celebrated for their long wars with the Caribs. In this labyrinth of petty nations, divided from one another as the nations of Latium, Asia Minor, and Sogdiana, formerly were, we can trace no general relations but by following the analogy of tongues. These are the only monuments that have reached us from the early ages of the world ; the only monuments, which, not being fixed to the soil, are at once moveable and lasting, and have as it were traversed time and space. They owe their duration, and the extent they occupy, much less to conquering and polished nations, than to those wandering and half-savage tribes, who, fleeing before a powerful enemy, carried along with them in their extreme wretchedness only their wives, their children, and the languages of their fathers. Between the latitudes of 4° and 8°, the Orinoco not only separates the great forest of the Parime from the bare savannahs of the Apure, Meta, and G-uaviare, but also forms the boundary between tribes of very different manners. To the westward, over treeless plains, wander the Gruahibos, the Chiricoas, and the Gruamos; nations, proud of their savage independence, whom it is difficult to fix to the soil, or habituate to regular labour. The Spanish missionaries characterise them well by the name of Indios andantes (errant or vagabond Indians), because they are perpetually moving from place to place. To the east of the Orinoco, between the neighbouring sources of the Caura, Cataniapo, OF IKDUTVg. 241 and Ventuari, live the Macos, the Salives, the Ciiracicanas, Parecas, and Maquiritares, mild, tranquil tribes, addicted to agriculture, and easily subjected to the discipline of the Missions. The Indian of the plains differs from the Indian of the forests in language as well as manners and mental disposition ; both have an idiom abounding in spirited and bold terms ; but the language of the former is harsher, more concise, and more impassioned; that of the latter, softer, more diffuse, and fuller of ambiguous expressions. The Mission of Atures, like most of the Missions of the Orinoco, situated between the mouths of the Apure and the Atabapo, is composed of both the classes of tribes we have just described. We there find the Indiana of the forests, and the Indians heretofore nomadic* (Indios monteros ami Indios llaneros, or andantes). We visited with the mis- fiionary the huts of Macos, whom the Spaniards call Piraoas, and those of the Guahibos. The first indicated more love of order, cleanliness, and ease. The independent Macos (I do not designate them by the name of savages) have their rochelas, or fixed dwellings, two or three days' journey east of Atures, toward the sources of the little river Cataniapo. They are very numerous. Lijce most of the natives of the woods, they cultivate, not maize, but cassava ; and they live in great harmony with the Christian Indians of the mission, The harmony was established and wisely cultivated by th* Franciscan monk, Bernardo Zea. This alcalde of the re- duced Macos quitted the village of Atures fbr a few months every year, to live in the plantations which he possessed in the midst of the forests near the hamlet of the independent Macos. In consequence of this peaceful intercourse, many of the Indios monteros came and established themselves some time ago in the mission. They asked eagerly for knives, fishing hooks, and those coloured glass-beads, which, not- withstanding the positive prohibition of the priests, were employed not as necklaces, but as ornaments of the guayuco (perizoma). Having obtained what they sought, they re- * I employ the word nomadic as synonymous with wandering, and not in its primitive signification. The wandering nations of America (those of ihe indigenous tribes, it is to be understood) are never shepherds ; th-;y live by tibhing and hunting, on the fruit of a few treei, the farma.vom pith of palm-trees, &c. TOL. II. ft 242 PREVALENCE OF FEYERS. turned to the woods, weary of the regulations of the mission. Epidemic fevers, which prevailed with violence at the en- trance of the rainy season, contributed greatly to this unex- pected flight. In 1799 the mortality was very considerable at Carichana, on the banks of the Meta, and at the Randal of Atures. The Indian of the forest conceives a horror of the life of the civilized man, when, I will not say any mis- fortune befalls his family settled in the mission, but merely any disagreeable or unforeseen accident. Natives, who were neophytes, have been known to desert for ever the Christian establishments, on account of a great drought; as if this calamity would not have reached them equally in their plan- tations, had they remained in their primitive independence. The fevers which prevail during a great part of the year in the villages of Atures and Maypures, around the two Great Cataracts of the Orinoco, render these spots highly dangerous to European travellers. They are caused by violent heats, in combination with the excessive humidity of the air, bad nutriment, and, if we may believe the natives, the pestilent exhalations rising from the bare rocks of the Eaudales. These fevers of the Orinoco appeared to us to resemble those which prevail every year between New Bar- celona, La Guayra, and Porto CabeUo, in the vicinity of the sea ; and which often degenerate into adynamic fevers. " I have had my little fever (mi calenturita) only eight months," said the good missionary of the Atures, who accompanied us to the Bio Negro ; speaking of it as of an habitual evil, easy to be borne. The fits were violent, but of short duration. He was sometimes seized with them when lying along in the boat under a shelter of branches of trees, sometimes when exposed to the burning rays of the sun on an open beach. These tertian agues are attended with great debility of the muscular system ; yet we find poor ecclesiastics on the Orinoco, who endure for several years these calentwritas, or tercianas : their effects are not so fatal as those which are experienced from fevers of much shorter duration in tem- perate climates. 1 have just alluded to the noxious influence on the salu- brity of the atmosphere, which is attributed by the natives, and even the missionaries, to the bare rocks. This opinion is the more worthy of attention, as it is connected with BOCK-IXCRUSTATIOyS. 213 R physical phenomenon lately observed in differ 3iit parts of the globe, and not yet sufficiently explained. Among the cataracts, and wherever the Orinoco, between, the Mis- sions of Carichana and of Santa Barbara, periodically washes the granitic rocks, they become smooth, black, and as il coated with plumbago. The colouring matter does not penetrate the stone, which is coarse-grained granite, con- taining a few solitary crystals of hornblende. Taking a general view of the primitive formation of Atures, we per- ceive, that, like the granite of Syene in Egypt, it is a granite with hornblende, and not a real syenite formation. Many of the layers are entirely destitute of hornblende. The black crust is 0'3 of a line in thickness; it is found chiefly on the quartzose parts. The crystals of feldspar sometimes pre- serve externally their reddish-white colour, and rise above the black crust. On breaking the stone with a hammer, the inside is found to be white, and without any trace of de- composition. These enormous stony masses appear some- times in rhombs, sometimes under those hemispheric forms, peculiar to granitic rocks when they separate in blocks. They give the landscape a singularly gloomy aspect; their colour being in strong contrast with that of the foam of the river which covers them, and of the vegetation by which they are surrounded. The Indians say, that the rocks are 'burnt' (or carbonized) 'by the rays of the sun.' We saw them not only in the bed of the Orinoco, but in some spots as far as five hundred toises from its present shore, on heights which the waters now never reach even in their greatest swellings. What is this brownish black crust, which gives these rocks, when they have a globular form, the appearance of meteoric stones ? What idea can we form of the action of the water, which produces a deposit, or a change of colour, so extraordinary ? We must observe, in the first place, that this phenomenon does not belong to the cataracts of the Orinoco alone, but is found in both hemispheres. At my return from Mexico in 1807, when I showed the granites of Atures and Maypures to M. Koziere, who had travelled over the valley ot Egypt, the coasts of the Bed Sea, and Mount Sinai, this learned geologist pointed out to me tha* the primitive rocka of the little cataracts )f Syene displq? n 2 2 14 »OcK-I2f CKUSTATION8. like the rocks of the Orinoco, a glossy surface, of a blackish* \?rey, or almost leaden colour, and of which some of the fragments seem coated with tar. Recently, in the un* fortunate expedition of Captain Tuckey, the English natu- ralists were struck with the same appearance in the yellalas (rapids and shoals) that obstruct the river Congo or Zaire. J)r. Koanig has placed in the British Museum, beside the syenites of the Congo, the granites of Atures, taken from a series of rocks which were presented by M. Bonpland and myself to the illustrious president of the Royal Society of London. "These fragments," says Mr. Koenig, "alike re- semble meteoric stones ; in both rocks, those of the Orinoco and of Africa, the black crust is composed, according to the analysis of Mr. Children, of the oxide of iron and man- ganese." Some experiments made at Mexico, conjointly with Senor del Rio, led me to think that the rocks of Atures, which blacken the paper in which they are wrapped,* contain, besides oxide of manganese, carbon, and supercarburetted iron. At the Orinoco, granitic masses of forty or fifty feet thick are uniformly coated with these oxides ; and, howevei thin these crusts may appear, they must nevertheless contain pretty considerable quantities of iron and manganese, since they occupy a space of above a league square. It must be observed that all these phenomena of colora- tion have hitherto appeared in the torrid zone only, in rivers that have periodical overflowings, of which the habitual temperature is from twenty-four to twenty-eight centesimal degrees, and which flow, not over gritstone or calcareous rocks, but over granite, gneiss, and hornblende rocks. Quartz and feldspar scarcely contain five or six thousandths of oxide of iron and of manganese ; but in mica and horn- blende these oxides, and particularly that of iron, amount, according to Klaproth and Herrmann, to fifteen or twenty parts in a hundred. The hornblende contains also some carbon, like the Lydian stone and kieselschiefer. Now, if these black crusts were formed by a slow decomposition of * I remarked the same phenomenon from spongy grains of platina one or two lines in length, collected at the stream-works of Taddo, in the pro- vince of Choco. Having been wrapped up in white paper during a journey of several months, they left a black stain, like that of plumbago or super- carburetted iron. THEIR ORIGIN*. 5Mt"> the granitic rock, under the double influence of humidity and the tropical sun, how is it to be conceived that these oxides are spread so uniformly over the whole surface of the stony masses, and are not more abundant round a crystal of mica or hornblende than on the feldspar and milky quartz? The ferruginous sandstones, granites, and marbles, that become cinereous and sometimes brown in damp air, have an aspect altogether different. In reflecting upon the lustre and equal thickness of the crusts, we are rather inclined to think that this matter is deposited by the Orinoco, and that the water has penetrated even into the clefts of the rocks. Adopting this hypothesis, it may be asked whether the river holds the oxides suspended like sand and other earthy substances, or whether they are found in a state of chemical solution. The first supposition is less admissible, on account of the homogeneity of the crusts, which contain neither grains of sand, nor spangles of mica, mixed with the oxides. We must then recur to the idea of a chemical solution ; and this idea is no way at variance with the phenomena daily observable in our labo- ratories. The waters of great rivers contain carbonic acid ; and, were they even entirely pure, they would still bo capable, in very great volumes, of dissolving some portions of oxide, or those metallic hydrates which are regarded as the least soluble. The mud of the Nile, which is the sediment of the matters which the river holds suspended, is destitute of manganese ; but it contains, according to the analysis of M. Eegnault, six parts in a hundred of oxide of iron ; and its colour, at first black, changes to yellowish brown by desiccation and the contact of air. The mud consequently is not the cause of the black crusts on the rocks of Syene. Berzelius, who, at my request, examined these crusts, recognized in them, as in those of the gra- nites of the Orinoco and Eiver Congo, the union of iron and manganese. That celebrated chemist was of opinion that the rivers do not take up these oxides from the soil over which they flow, but that they derive them from their sub- terranean sources, and deposit them on the rocks in the Manner of cementation, by the action of particular aflini- ties, perhaps by that of the potash of the feldspar. A long residence at the cataracts of the Orinoco, the >ale, and the 246 POPITLAE PREJUDICE. Rio Congo, and an examination of the circumstances atten- dant on this phenomenon of coloration, could alone "lead to the complete solution of the problem we have discussed. Is this phenomenon independent of the nature of the rocks ? I shall content myself with observing, in general, that neither the granitic masses remote from the ancient bed of the Orinoco, but exposed during the rainy season to the alternations of heat and moisture, nor the granitic rocks bathed by the brownish waters of the Eio Negro, assume the appearance of meteoric stones. The Indians say, " that the rocks are black only where the waters are white." They ought, perhaps, to add, " where the waters acquire great swift- ness, and strike with force against the rocks of the banks." Cementation seems to explain why the crusts augment so little in thickness. I know not whether it be an error, but in the Missions ef the Orinoco, the neighbourhood of bare rocks, and espe- cially of the masses that have crusts of carbon, oxide of iron, and manganese, are considered injurious to health. In the torrid zone, still more than in others, the people multiply pathogenic causes at will. They are afraid to sleep in the open air, if forced to expose the face to the rays of the full moon. They also think it dangerous to sleep on granite near the river ; and many examples are cited of persons, who, after having passed the night on these black and naked rocks, have awakened in the morning with a strong paroxysm of fever. Without entirely lending faith to the assertions of the missionaries and natives, we generally avoided the laxas negras, and stretched ourselves on the beach covered with white sand, when we found no tree from which to suspend our hammocks. At Carichana, the village is intended to be destroyed, and its place changed, merely to remove it from the ' black rocks,' or from a site where, for a space of more than ten thousand square toises, banks of bare granite form the surface. From similar motives, which must appear very chimerical to the natu- ralists of Europe, the Jesuits Olmo, Forneri, and Mellis, removed a village of Jaruros to three different spots, be- tween the Raudal of Tabaje and the Eio Anaveni. I merely atate these facts as they were related to me, because we are almost wholly ignorant of the nature of the gaseous mixtures HEAT OF THE ROCKS. 247 which cause the insalubrity of the atmosphere. Can it be admitted that, under the influence of excessive heat and of constant humidity, the black crusts of the granitic rocks are capable of acting upon the ambient air, and producing miasmata with a triple basis of carbon, azote, and hydrogen ? This I doubt. The granites of the Orinoco, it is true, often contain hornblende; and those who are accustomed to practical labour in mines are not ignorant that the most noxious exhalations rise from galleries wrought in syenitic and hornblende rocks : but in an atmosphere renewed every instant by the action of little currents of air, the effect can- not be the same as in a mine. It is probably dangerous to sleep on the laxas negras, only because these rocks retain a very elevated temperature during the night. I have found their temperature in the day at 48°, the air in the shade being at 29*7° ; during the night the thermometer on the rock indicated 36°, the air being at 26°. When the accumulation of heat in the stony masses has reached a stationary degree, these masses be- come at the same hours nearly of the same temperature. What they have acquired more in the day they lose at night by radiation, the force of which depends on the state of the surface of the radiating body, the interior arrangement of its particles, and, above all, on the clearness of the sky, that is, on the transparency of the atmosphere and the absence of clouds. When the declination of the sun varies very little, this luminary adds daily nearly the same quantities of heat, and the rocks are not hotter at the end than in the middle of summer. There is a certain maximum which they cannot pass, because they do not change the state of their surface, their density, or their capacity for caloric. On the shores of the Orinoco, on getting out of one's ham- mock during the night, and touching with the bare feet the rocky surface of the ground, the sensation of heat expe- rienced is very remarkable. I observed pretty constantly, in putting the bulb of the thermometer in contact with tlie ledges of bare rocks, that the laxas negras are hotter during the day than the reddish-white granites at a distance from the river ; but the latter cori during the night less rapidly than the former. It may be easily conceived that the emission and loss of caloric is more rapid in masses with 248 THI^JCESS OF TUB POITLATION. black crusts than in those which abound in lamina of silvery mica. When walking between the hours of one and three m the afternoon, at Carichana, Atures, or Maypures, among those blocks of stone destitute of vegetable mould, and piled up to great heights, one feels a sensation of suffocation, as if standing before the opening of a furnace. The winds, if ever felt m those woody regions, far from bringing coolness, appear more heated when they have passed over beds of stone, and heaps of rounded blocks of granite. This aug- mentation of heat adds to the insalubrity of the climate. Among the causes of the depopulation of the Eaudales, I have not reckoned the small-pox, that malady which in other parts of America makes such cruel ravages that the natives, seized with dismay, burn their huts, kill their children, and renounce every kind of society. This scourge is almost unknown on the banks of the Orinoco, and should it penetrate thither, it is to be hoped that its effects may be immediately counteracted by vaccination, the blessings if which are 'daily felt along the. coasts of Terra Firma. The causes which depopulate the Christian settlements are, the repugnance of the Indians for the regulations of the missions, insalubrity of climate, bad nourishment, want of care in the diseases of children, and the guilty practice of preventing pregnancy by the use of deleterious herbs. Among the barbarous people of Gluiana, as well as those of the half-civilized islands of the South Sea, young wives are fearful of becoming mothers. If they have chil- dren, their offspring are exposed not only to the dangers of savage life, but also to other dangers arising from the strangest popular prejudices. When twins are born, false notions of propriety and family honour require that one of them should be destroyed. " To bring twins into the world," say the Indians, " is to be exposed to public scorn ; it is to resemble rats, opossums, and the vilest animals, which bring forth a great number of young at a time.'* Nay, more, they affirm that " twro children born at the same tine cannot belong to the same father." This is an axiom of physiology among the Salives ; and in every zone, and in different states of society, when the vulgar seize upon an axiom, they adhere to it with more stedfastness than the better-informed men by whom it was first hazarded. To ITS PROBABLE CAUSES. 240 avoid the disturbance of conjugal tranquillity, the old female relations of the mother take care, that when twins axe born one of them shall disappear. If a new-born infant, though not a twin, have any physical deformity, the father instantly puts it to death. They will have none but robust and well- made children, for deformities indicate some influence of the evil spirit loloquiamo, or the bird Tikitiki, the enemy of the human race. Sometimes children of a feeble con- stitution undergo the same fate. When the father is asked what is become of one of his sons, he will pretend that he has lost him by a natural death. He will disavow an action that appears to him blameable, but not criminal. "The ")oor boy," he will tell you, "could not follow us; we must have waited for him every moment ; he has not been seen again ; he did not come to sleep where we passed the night." Such is the candour and simplicity of manners — such the boasted happiness — of man in the state of nature ! He kills his son to escape the ridicule of having twins, or to avoid journeying more slowly; in fact, to avoid a little incon- venience. These acts of cruelty, I confess, are less frequent than they are believed to be ; yet they occur even in the Missions, during the time when the Indians leave the village, to retire to the conucos of the neighbouring forests. It would be erroneous to attribute these actions to the state of polygamy in which the uncatechized Indians live. Polygamy no doubt diminishes the domestic happiness and internal union of families; but this practice, sanctioned by Ismaelism, does not prevent the people of the east from loving their children with tenderness. Among the Indians of the Orinoco, the father returns home only to eat, or to sleep in his hammock ; he lavishes no caresses on his infants, or on his wives, whose office it is to serve him. Parental affection begins to display itself only when the son has become strong enough to take a part in hunting, fishing, and the agricultural labours of the plantations. While our boat was unloading, we examined closely, wherever the shore could be approached, the terrific spec- tacle of a great river narrowed and reduced as it were to foam. I shall endeavour to paint, not the sensations we felt, but the aspect of a spot so celebrated among the scene* of 250 NATURAL RAFTS. H the New World. The more imposing and majestic the object* we describe, the more essential it becomes to seize them in their smallest details, to fix the outline of the picture we would present to the imagination of the reader, and to describe with simplicity what characterises the great and imperishable monuments of nature. The navigation of the Orinoco from its mouth as far as the confluence of the Anaveni, an extent of 260 leagues, is not impeded. There are shoals and eddies near Muitaco, in a cove that bears the name of the Mouth of Hell (Boca del Infierno) ; and there are rapids (raudalitos) near Cari- chana and San Borja ; but in all these places the river ia never entirely barred, as a channel is left by which boats can pass up and down. In all this navigation of the Lower Orinoco travellers experience no other danger than that of the natural rafts formed by trees, which are uprooted by the river, and swept along in its great floods. "Woe to the canoes that during the night strike against these rafts of wood interwoven with lianas ! Covered with aquatic plants, they rest- ible here, as in the Mississippi, floating meadows, the chinampas or floating gardens of the Mexican lakes. The Indians, when they wish to surprise a tribe of their enemies, bring together several canoes, fasten them to each other with cords, and cover them with grass and branches, to imitate this assemblage of trunks of trees, which the Orinoco sweeps along in its middle current. The Caribs are ac- cused of having heretofore excelled in the use of this artifice; at present the Spanish smugglers in the neigh- bourhood of Angostura have recourse to the same expedient to escape the vigilance of the custom-house officers. After proceeding up the Orinoco beyond the .Rio Ana- veni, we find, between the mountains of Uniana and Sipapu, the Great Cataracts of Mapara and Quittuna, or, as they are more commonly called by the missionaries, the Raudales of Atures and Maypures. These bars, which extend from one bank to the other, present in general a similar aspect : they are composed of innumerable islands, dikes of rock, and blocks of granite piled on one another and covered with palm-trees. But, notwithstanding a uniformity of aspect, each of these cataracts preserves an individual character. OBIGIS Or THE AMAZON. 251 The first, the Atures, is most easily passable when the waters are low. The Indians prefer crossing the second, the Maypures, at the time of great floods. Beyond the Maypures and the mouth of the Cano Cameji, the Orinoco is again unobstructed for the length of more than one hundred and sixty-seven leagues, or nearly to its source; that is to say, as far as the Baudalito of Guaharibos, east of the Cano Chiguire and the lofty mountains of Yurnariquin. Having visited the basins of the two rivers Orinoco and Amazon, I was singularly struck by the differences they display in their course of unequal extent. The falls of the Amazon, which is nearly nine hundred and eighty nautical leagues (twenty to a degree) in length, aro pretty near its source in the first sixth of its total length, and five-sixths of its course are entirely free. "We find the great falls of the Orinoco on a point far more unfavourable to navigation ; if not at the half, at least much beyond the first third of its length. In both rivers it is neither the mountains, nor the different stages of flat lands lying over one another, whence they take their origin, that cause the cataracts ; they are produced by other mountains, other ledges which, after a long and tranquil course, the rivers have to pass over, precipitating themselves from step to step. The Amazon does not pierce its way through the prin- cipal chain of the Andes, as was affirmed at a period when it was gratuitously supposed that, wherever mountains are divided into parallel chains, the intermedial or central ridge must be more elevated than the others. This great river rises (and this is a point of some importance to geology) eastward of the western chain, which alone in this latitude merits the denomination of the high chain of the Andes. It is formed by the junction of the river Aguamiros with the Bio Chavinillo, which issues from the lake Llauricocha in a longitudinal valley bounded by the western and the intermedial chain of the Andes. To form an accurate idea of these hydrographical relations, it must be borne in mind that a division into three chains takes place in the colossal group or knot of the mountains of Pasco and Huanuco. The western chain, which is the loftiest, and takes the name of the Cordillera Real de Nieve, directs its course (between lluary and Caxatamba, Guamachuco and Luc-ma, Micui- 252 GEXEIIAL COUESE OF THE AMAZON. pampa and Gruangamarca) by the Nevados of Viuda, Pela- gatos, Moyopata, and Huaylillas, and by the Paramos of (jriiamani and Gruaringa, towards the town of Loxa. The intermedia! chain separates the waters of the Upper Mara- fion from those of the Guallaga, and over a long space reaches only the small elevation of a thousand toises; it enters the region of perpetual snow to the south of Huanuco in the Cordillera of Sasaguanca. It stretches at first northward by Huacrachuco, Chachapoyas, Moyobamba, and the Paramo of Piscoguannuna ; then it progressively lowers toward Peca, Copallin, and the Mission of Santiago, at the eastern extremity of the province of Jaen de Braca- rnoros. The third, or easternmost chain, skirts the right bank of the Bio Gruallaga, and loses itself in the seventh degree of latitude. So long as the Amazon flows froo south to north in the longitudinal valley, between twc chains of unequal height (that is, from the farms of Qui- villa and Gruancaybamba, where the river is crossed on wooden bridges, as far as the confluence of the Rio Chin- chipe), there are neither bars, nor any obstacle whatever to the navigation of boats. The falls of water begin only where the Amazon turns toward the east, crossing the intermedia! chain of the Andes, which widens considerably toward the north. It meets with the first rocks of red sandstone, or ancient conglomerate, between Tambillo and the Pongo of Rentema (near which I measured the breadth, depth, and swiftness of the waters), and it leaves the rocks of red sandstone east of the famous strait of Manseriche, near the Pongo of Tayuchuc, where the hills rise no higher than forty or fifty toises above the level of its waters. The river does not reach the most easterly chain, which bounds the Pampas del Sacramento. From the hills of Tayuchuc as far as Grand Para, during a course of more than seven hundred and fifty leagues, the navigation is free from obstacles. It results from this rapid sketch, that, if the Maranon had not to pass over the hilly country between Santiago and Tomependa (which belongs to the central chain of the Andes) it would be navigable from its mouth as far as Pumpo, near Piscobamba in the province of Con- chucos, forty-three leagues north of its source. We have just seen that, in the Orinoco, as in the Amazon, THE GHEAT CATARACTS. 253 the great cataracts are not found near the sources of the rivers. After a tranquil course of more than one hundred and sixty leagues from the little Raudal of Guaharibos, east of Esmeralda, as far as the mountains of Sipapu, the river, augmented by the waters of the Jao, the Ventuari, the Atabapo, and the Guaviare, suddenly changes its primitive direction from east to west, and runs from south to north : then, in crossing the land-strait* in the plains of Meta, meets the advanced buttresses of the Cordillera of Parima. This obstacle causes cataracts far more considerable, and presents greater impediments to navigation, than all the Pongos of the Upper Marafion, because they are propor- tionally nearer to the mouth of the river. These geogra- phical details serve to prove, in the instances of the two greatest rivers of the New World, 1st, that it cannot be ascertained in an absolute manner that, beyond a certain number of toises, or a certain height above the level of the sea, rivers are not navigable ; 2ndly, that the rapids are not always occasioned, as several treatises of general topography affirm, by the height of the first obstacles, by the first lines of lidges which the waters have to surmount near their sources. The most northern of the great cataracts of the Orinoco is the only one bounded on each side by lofty mountains. The left bank of the river is generally lower, but it makes part of a plane which rises again west of Atures, towards the Peak of Uniana, a pyramid nearly three thousand feet high, and placed on a wall of rock with steep slopes. The situa- tion of this solitary peak in the plain contributes to render its aspect more imposing and majestic. Near the Mission, in the country which surrounds the cataract, the aspect of the landscape varies at every step. Within a small space we find all that is most rude and gloomy in nature, united with an open country and lovely pastoral scenery. In the physical, as in the moral world, the contrast of effects, the comparison of what is powerful and menacing with what ia soft and peaceful, is a never-failing source of our pleasures and our emotions. J shall here repeat some scattered features of a picture • This strait, which I have several times mentioned, is formed by th« Cordilleras of ihe Andes of New Granada, and the Cordillera of Parima. 254 SAVAX^HS OF whi-'h I traced in another work shortly after my return to Europe.* The savannahs of Atures, covered with slender plants and grasses, are really meadows resembling those of Europe. They are never inundated by the rivers, and seem as if waiting to be ploughed by the hand of man. Notwith- standing their extent, these savannahs do not exhibit the monotony of our plains ; they surround groups of rocks and blocks of granite piled on one another. On the very bor- ders of these plains and this open country, glens are seen scarcely lighted by the rays of the setting sun, and hollows where the humid soil, loaded with arums, heliconias, and lianas, manifests at every step the wild fecundity of nature. Everywhere, just rising above the earth, appear those shelves of granite completely bare, which we saw at Cari- chana, and which I have already described. "Where springs gush from the bosom of these rocks, verrucarias, psoras, and lichens are fixed on the decomposed granite, and have there accumulated mould. Little euphorbias, peperomias, and other succulent plants, have taken the place of the crypto- gamous tribes ; and evergreen shrubs, rhexias, and purple- flowered melastomas, form verdant isles amid desert and rocky plains. The distribution of these spots, the clusters of small trees with coriaceous and shining leaves scattered in the savannahs, the limpid rills that dig channels across the rocks, and wind alternately through fertile places and over bare shelves of granite, all call to mind the most lovely and picturesque plantations and pleasure-grounds of Europe. We seem to recognise the industry of man, and the traces of cultivation, amid this wild scenery. The lofty mountains that bound the horizon on every side, contribute also, by their forms and the nature of their vegetation, to give an extraordinary character to the land- scape. The average height of these mountains is not more than seven or eight hundred feet above the surrounding plains. Their summits are rounded, as for the most part in granitic mountains, and covered with thick forests of the laurel-tribe. Clusters of palm-trees,t the leaves of which, curled like feathers, rise majestically at an angle of seventy 3, are dispersed amid trees with horizontal branches • * Views of Nature, p. 153 (Bohn's edition). f Elcucurito. TROPICAL SCENERY. 256 and ilicir bare trunks, like columns of a hundred or a hundred and twenty feet high, shoot up into the air, and when seen in distinct relief against the azure vault of the sky, they resemble a forest planted upon another forest. When, as the moon was going down behind the mountains of Uniana, her reddish disc was hidden behind the pinnated foliage of the palm-trees, and again appeared in the aerial zone that separates the two forests, I thought myself trans- ported for a few moments to the hermitage which Bernardin de Saint-Pierre has described as one of the most delicious scenes of the Isle of Bourbon, and I felt how much the aspect of the plants and their groupings resembled each other in the two worlds. In describing a small spot of land in an island of the Indian Ocean, the inimitable author of Paul and Virginia has sketched the vast picture of the land- scape of the tropics. He knew how to paint nature, not because he had studied it scientifically, but because he felt it in all its harmonious analogies of forms, colours, and interior powers. East of the Atures, near these rounded mountains crowned, as it were, by two superimposed forests of laurels and palms, other mountains of a very different aspect arise. Their ridge is bristled with pointed rocks, towering like pillars above the summits of the trees and shrubs. These effects are common to all granitic table-lands, at the Harz, in the metalliferous mountains of Bohemia, in Galicia, on the limit of the two Castiles, or wherever a granite of new formation appears above the ground. The rocks, which are at distances from each other, are composed of blocks piled together, or divided into regular and horizontal beds. On the summits of those situated near the Orinoco, flamingos, soldados* and other fishing-birds perch, and look like men posted as sentinels. This resemblance is so striking, that the inhabitants of Angostura, soon after the foundation of their city, were one day alarmed by the sudden appearance of soldados and garzas, on a mountain towards the south. They believed they were menaced with an attack of Indios monteros (wild Indians called mountaineers) ; and the people Were not perfectly tranquillized, till they saw the birds soar- * The ioldado (soldier) U a *arge species of heron. 256 LUXURIANCE OF VEGETATION. ing in the air, and continuing their migration x wards thp mouths of the Orinoco. The fine vegetation of the mountains spreads over the plains, wherever the rock is covered with mould. We generally find that this black mould, mixed with fibrous vegetable matter, is separated from the granitic rock by a layer of white sand. The missionary assured us that verdure of perpetual freshness prevails in the vicinity of the cataracts, produced by the quantity of vapour which the river, broken into torrents and cascades for the length of three or four thousand toises, diffuses in the air. We had not heard thunder more than once or twice at Atures, and the vegetation everywhere displayed that vigorous aspect, that brilliancy of colour, seen on the coast only at the end of the rainy season. The old trees were decorated with beautiful orchideas,* yellow bannisterias, blue-flowered bignonias, peperomias, arums, and pothoses, A single trunk displays a greater variety of vegetable forms than are con- tained within an extensive space of ground in our countries. Close to the parasite plants peculiar to very hot climates we observed, not without surprise, in the centre of the torrid zone, and near the level of the sea, mosses resembling in every respect those of Europe. "We gathered, near the Great Cataract of Atures, that fine specimen of Grimmiaf with fontinaljs leaves, which has so much fixed the attention of botanists. It is suspended to the branches of the loftiest trees. Of the phanerogamous plants, those which prevail in the woody spots are the mimosa, ficus, and laurinea. This fact is the more characteristic as, according to the observations of Mr. Brown, the Iaurinea3 appear to be almost entirely wanting on the opposite continent, in the equinoctial part of Africa. Plants that love humidity adorn the scenery surrounding the cataracts. We there find in the plains groups of heliconias and other scitamineaB with large and glossy leaves, bamboos, and the three palm-trees, the murichi, * Cymbidium violaceura, Habenaria angustifolia, &e. i Grimmia fontinakndes.

STATELY PALM-TREES. 257 jaqua, and vadgiai, each of which forms a separate group. The mwrichi, or mauritia with scaly fruits, is the celebrated sago-tree of the G-uaraon Indians. It lias palmate leaves, and has no relation to the palm-trees with pinnate and curled leaves ; to ihejagua, which appears to be a species of the cocoa-tree ; or to the vadgiat or cucurito, which may be assimilated to the fine species Oreodoxa. The cucurito, which is the palm most prevalent around the cataracts of the Atures and Maypures, is remarkable for its stateliness. Its leaves, or rather its palms, crown a trunk of eighty or one hundred feet high ; their direction is almost perpen- dicular when young, as well as at their full growth, the points only being incurvated. They look like plumes of the most soft and verdant green. The cucurito, the pirijao, the fruit of which resembles the apricot, the Oreodoxa regia or valma real of the island of Cuba, and the ceroxylon of the high Andes, are the most majestic of all the palm-trees we
