Advancing towards the west, we find the hills or islets in the deserted branch of the Orinoco crowned with the same palm-trees that rise on the rocks of the cataracts. One of these hills, called Keri, is celebrated in the country on account of a white spot which shines from afar, and in which the natives profess to see the image of the full moon. I could not climb this steep rock, but I believe the white spot to be a large nodule of quartz, formed by the union of several of those veins so common in granites pa.s.sing into gneiss. Opposite Keri, or the Rock of the Moon, on the twin mountain Ouivitari, which is an islet in the midst of the cataracts, the Indians point out with mysterious awe a similar white spot. It has the form of a disc; and they say this is the image of the sun (Camosi). Perhaps the geographical situation of these two objects has contributed to their having received these names. Keri is on the side of the setting, Camosi on that of the rising sun. Languages being the most ancient historical monuments of nations, some learned men have been singularly struck by the a.n.a.logy between the American word camosi and camosch, which seems to have signified originally, the sun, in one of the Semitic dialects. This a.n.a.logy has given rise to hypotheses which appear to me at least very problematical. The G.o.d of the Moabites, Chemosh, or Camosch, who has so wearied the patience of the learned; Apollo Chomens, cited by Strabo and by Ammia.n.u.s Marcellinus; Belphegor; Amun or Hamon; and Adonis: all, without doubt, represent the sun in the winter solstice; but what can we conclude from a solitary and fortuitous resemblance of sounds in languages that have nothing besides in common?
The Maypure tongue is still spoken at Atures, although the mission is inhabited only by Guahibos and Macos. At Maypures the Guareken and Pareni tongues only are now spoken. From the Rio Anaveni, which falls into the Orinoco north of Atures, as far as beyond Jao, and to the mouth of the Guaviare (between the fourth and sixth degrees of lat.i.tude), we everywhere find rivers, the termination of which, veni,*
(* Anaveni, Mataveni, Maraveni, etc.) recalls to mind the extent to which the Maypure tongue heretofore prevailed. Veni, or weni, signifies water, or a river. The words camosi and keri, which we have just cited, are of the idiom of the Pareni Indians,* (* Or Parenas, who must not be confounded either with the Paravenes of the Rio Caura (Caulin page 69), or with the Parecas, whose language belongs to the great family of the Tamanac tongues. A young Indian of Maypures, who called himself a Paragini, answered my questions almost in the same words that M. Bonpland heard from a Pareni. I have indicated the differences in the table, see below.) who, I think I have heard from the natives, lived originally on the banks of the Mataveni.* (* South of the Rio Zama. We slept in the open air near the mouth of the Mataveni on the 28th day of May, in our return from the Rio Negro.) The Abbe Gili considers the Pareni as a simple dialect of the Maypure.
This question cannot be solved by a comparison of the roots merely.
Being totally ignorant of the grammatical structure of the Pareni, I can raise but feeble doubts against the opinion of the Italian missionary. The Pareni is perhaps a mixture of two tongues that belong to different families; like the Maquiritari, which is composed of the Maypure and the Caribbee; or, to cite an example better known, the modern Persian, which is allied at the same time to the Sanscrit and to the Semitic tongues. The following are Pareni words, which I carefully compared with Maypure words.*

I may here mention, that the word Teo, or Teot, which in Aztec signifies G.o.d (Teotl, properly Teo, for tl is only a termination), is found in the language of the Betoi of the Rio Meta.
The name of the moon, in this language so remarkable for the complication of its grammatical structure, is Teo-ro. The name of the sun is Teo-umasoi. The particle ro designates a woman, umasoi a man.
Among the Betoi, the Maypures, and so many other nations of both continents, the moon is believed to be the wife of the sun. But what is this root Teo? It appears to me very doubtful, that Teo-ro should signify G.o.d-woman, for Memelu is the name of the All-powerful Being in the Betoi langnage.)

This comparison seems to prove that the a.n.a.logies observed in the roots of the Pareni and the Maypure tongues are not to be neglected; they are, however, scarcely more frequent than those that have been observed between the Maypure of the Upper Orinoco and the language of the Moxos, which is spoken on the banks of the Marmora, from 15 to 20 degrees of south lat.i.tude. The Parenis have in their p.r.o.nunciation the English th, or tsa of the Arabians, as I clearly heard in the word Amethami (devil, evil spirit). I need not again notice the origin of the word camosi. Solitary resemblances of sounds are as little proof of communication between nations as the dissimilitude of a few roots furnishes evidence against the affiliation of the German from the Persian and the Greek. It is remarkable, however, that the names of the sun and moon are sometimes found to be identical in languages, the grammatical construction of which is entirely different; I may cite as examples the Guarany and the Omagua,* languages of nations formerly very powerful. (* Sun and Moon, in Guarany, Quarasi and Jasi; in Omagua, Huara.s.si and Jase. I shall give, farther on, these same words in the princ.i.p.al languages of the old and new worlds. See note below.) It may be conceived that, with the worship of the stars and of the powers of nature, words which have a relation to these objects might pa.s.s from one idiom to another. I showed the constellation of the Southern Cross to a Pareni Indian, who covered the lantern while I was taking the circ.u.m-meridian heights of the stars; and he called it Bahumehi, a name which the caribe fish, or serra salme, also bears in Pareni. He was ignorant of the name of the belt of Orion; but a Poignave Indian,* who knew the constellations better, a.s.sured me that in his tongue the belt of Orion bore the name of Fuebot; he called the moon Zenquerot. (* At the Orinoco the Puignaves, or Poignaves, are distinguished from the Guipunaves (Uipunavi). The latter, on account of their language, are considered as belonging to the Maypure and Cabre nations; yet water is called in Poignave, as well as in Maypure, oueni.) These two words have a very peculiar character for words of American origin. As the names of the constellations may have been transmitted to immense distances from one nation to another, these Poignave words have fixed the attention of the learned, who have imagined they recognize the Phoenician and Moabite tongues in the word camosi of the Pareni. Fuebot and zenquerot seem to remind us of the Phoenician words mot (clay), ardod (oak-tree), ephod, etc. But what can we conclude from simple terminations which are most frequently foreign to the roots? In Hebrew the feminine plurals terminate also in oth. I noted entire phrases in Poignave; but the young man whom I interrogated spoke so quick that I could not seize the division of the words, and should have mixed them confusedly together had I attempted to write them down.* (* For a curious example of this, see the speech of Artabanes in Aristophanes (Acharn. act 1 scene 3) where a Greek has attempted to give a Persian oration. See also Gibbon"s Roman Empire chapter 53 note 54, for a curious example of the way in which foreign languages have been disfigured when it has been attempted to represent them in a totally different tongue.)
The Mission near the raudal of Maypures was very considerable in the time of the Jesuits, when it reckoned six hundred inhabitants, among whom were several families of whites. Under the government of the Fathers of the Observance the population was reduced to less than sixty. It must be observed that in this part of South America cultivation has been diminishing for half a century, while beyond the forests, in the provinces near the sea, we find villages that contain from two or three thousand Indians. The inhabitants of Maypures are a mild, temperate people, and distinguished by great cleanliness. The savages of the Orinoco for the most part have not that inordinate fondness for strong liquors which prevails in North America. It is true that the Ottomacs, the Jaruros, the Achaguas, and the Caribs, are often intoxicated by the immoderate use of chiza and many other fermented liquors, which they know how to prepare with ca.s.sava, maize, and the saccharine fruit of the palm-tree; but travellers have as usual generalized what belongs only to the manners of some tribes. We were frequently unable to prevail upon the Guahibos, or the Maco-Piroas, to taste brandy while they were labouring for us, and seemed exhausted by fatigue. It will require a longer residence of Europeans in these countries to spread there the vices that are already common among the Indians on the coast. In the huts of the natives of Maypures we found an appearance of order and neatness, rarely met with in the houses of the missionaries.
These natives cultivate plantains and ca.s.sava, but no maize. Ca.s.sava, made into thin cakes, is the bread of the country. Like the greater part of the Indians of the Orinoco, the inhabitants of Maypures have beverages which may be considered nourishing; one of these, much celebrated in that country, is furnished by a palm-tree which grows wild in the vicinity of the mission on the banks of the Auvana. This tree is the seje: I estimated the number of flowers on one cl.u.s.ter at forty-four thousand; and that of the fruit, of which the greater part fall without ripening, at eight thousand. The fruit is a small fleshy drupe. It is immersed for a few minutes in boiling water, to separate the kernel from the parenchymatous part of the sarcocarp, which has a sweet taste, and is pounded and bruised in a large vessel filled with water. The infusion yields a yellowish liquor, which tastes like milk of almonds. Sometimes papelon (unrefined sugar) is added. The missionary told us that the natives become visibly fatter during the two or three months in which they drink this seje, into which they dip their cakes of ca.s.sava. The piaches, or Indian jugglers, go into the forests, and sound the botuto (the sacred trumpet) under the seje palm-trees, to force the tree, they say, to yield an ample produce the following year. The people pay for this operation, as the Mongols, the Arabs, and nations still nearer to us, pay the chamans, the marabouts, and other cla.s.ses of priests, to drive away the white ants and the locusts by mystic words or prayers, or to procure a cessation of continued rain, and invert the order of the seasons.
"I have a manufacture of pottery in my village," said Father Zea, when accompanying us on a visit to an Indian family, who were occupied in baking, by a fire of brushwood, in the open air, large earthen vessels, two feet and a half high. This branch of manufacture is peculiar to the various tribes of the great family of Maypures, and they appear to have followed it from time immemorial. In every part of the forests, far from any human habitation, on digging the earth, fragments of pottery and delf are found. The taste for this kind of manufacture seems to have been common heretofore to the natives of both North and South America. To the north of Mexico, on the banks of the Rio Gila, among the ruins of an Aztec city; in the United States, near the tumuli of the Miamis; in Florida, and in every place where any traces of ancient civilization are found, the soil covers fragments of painted pottery; and the extreme resemblance of the ornaments they display is striking. Savage nations, and those civilized people* (* The Hindoos, the Tibetians, the Chinese, the ancient Egyptians, the Aztecs, the Peruvians; with whom the tendency toward civilization in a body has prevented the free development of the faculties of individuals.) who are condemned by their political and religious inst.i.tutions always to imitate themselves, strive, as if by instinct, to perpetuate the same forms, to preserve a peculiar type or style, and to follow the methods and processes which were employed by their ancestors. In North America, fragments of delf ware have been discovered in places where there exist lines of fortification, and the walls of towns constructed by some unknown nation, now entirely extinct. The paintings on these fragments have a great similitude to those which are executed in our days on earthenware by the natives of Louisiana and Florida. Thus too, the Indians of Maypures often painted before our eyes the same ornaments as those we had observed in the cavern of Ataruipe, on the vases containing human bones. They were grecques, meanders, and figures of crocodiles, of monkeys, and of a large quadruped which I could not recognize, though it had always the same squat form. I might hazard the hypothesis that it belongs to another country, and that the type had been brought thither in the great migration of the American nations from the north-west to the south and south-east; but I am rather inclined to believe that the figure is intended to represent a tapir, and that the deformed image of a native animal has become by degrees one of the types that has been preserved.
The Maypures execute with the greatest skill grecques, or ornaments formed by straight lines variously combined, similar to those that we find on the vases of Magna Grecia, on the Mexican edifices at Mitla, and in the works of so many nations who, without communication with each other, find alike a sensible pleasure in the symmetric repet.i.tion of the same forms. Arabesques, meanders, and grecques, please our eyes, because the elements of which their series is composed, follow in rhythmic order. The eye finds in this order, in the periodical return of the same forms, what the ear distinguishes in the cadenced succession of sounds and concords. Can we then admit a doubt that the feeling of rhythm manifests itself in man at the first dawn of civilization, and in the rudest essays of poetry and song?
Among the natives of Maypures, the making of pottery is an occupation princ.i.p.ally confined to the women. They purify the clay by repeated washings, form it into cylinders, and mould the largest vases with their hands. The American Indian is unacquainted with the potter"s wheel, which was familiar to the nations of the east in the remotest antiquity. We may be surprised that the missionaries have not introduced this simple and useful machine among the natives of the Orinoco, yet we must recollect that three centuries have not sufficed to make it known among the Indians of the peninsula of Araya, opposite the port of c.u.mana. The colours used by the Maypures are the oxides of iron and manganese, and particularly the yellow and red ochres that are found in the hollows of sandstone. Sometimes the fecula of the Bignonia chica is employed, after the pottery has been exposed to a feeble fire. This painting is covered with a varnish of algarobo, which is the transparent resin of the Hymenaea courbaril. The large vessels in which the chiza is preserved are called ciamacu, the smallest bear the name of mucra, from which word the Spaniards of the coast have framed murcura. Not only the Maypures, but also the Guaypunaves, the Caribs, the Ottomacs, and even the Guamos, are distinguished at the Orinoco as makers of painted pottery, and this manufacture extended formerly towards the banks of the Amazon.
Orellana was struck with the painted ornaments on the ware of the Omaguas, who in his time were a populous commercial nation.
The following facts throw some light on the history of American civilization. In the United States, west of the Allegheny mountains, particularly between the Ohio and the great lakes of Canada, on digging the earth, fragments of painted pottery, mingled with bra.s.s tools, are constantly found. This mixture may well surprise us in a country where, on the first arrival of Europeans, the natives were ignorant of the use of metals. In the forests of South America, which extend from the equator as far as the eighth degree of north lat.i.tude, from the foot of the Andes to the Atlantic, this painted pottery is discovered in the most desert places, but it is found accompanied by hatchets of jade and other hard stones, skilfully perforated. No metallic tools or ornaments have ever been discovered; though in the mountains on the sh.o.r.e, and at the back of the Cordilleras, the art of melting gold and copper, and of mixing the latter metal with tin to make cutting instruments, was known. How can we account for these contrasts between the temperate and the torrid zone? The Incas of Peru had pushed their conquests and their religious wars as far as the banks of the Napo and the Amazon, where their language extended over a small s.p.a.ce of land; but the civilization of the Peruvians, of the inhabitants of Quito, and of the Muyscas of New Grenada, never appears to have had any sensible influence on the moral state of the nations of Guiana. It must be observed further, that in North America, between the Ohio, Miami, and the Lakes, an unknown people, whom systematic authors would make the descendants of the Toltecs and Aztecs, constructed walls of earth and sometimes of stone without mortar,*
from ten to fifteen feet high, and seven or eight thousand feet long.
(* Of siliceous limestone, at Pique, on the Great Miami; of sandstone at Creek Point, ten leagues from Chillakothe, where the wall is fifteen hundred toises long.) These singular circ.u.mvallations sometimes enclosed a hundred and fifty acres of ground. In the plains of the Orinoco, as in those of Marietta, the Miami, and the Ohio, the centre of an ancient civilization is found in the west on the back of the mountains; but the Orinoco, and the countries lying between that great river and the Amazon, appear never to have been inhabited by nations whose constructions have resisted the ravages of time. Though symbolical figures are found engraved on the hardest rocks, yet further south than eight degrees of lat.i.tude, no tumulus, no circ.u.mvallation, no dike of earth similar to those that exist farther north in the plains of Varinas and Canagua, has been found. Such is the contrast that may be observed between the eastern parts of North and South America, those parts which extend from the table-land of Cundinamarca* (* This is the ancient name of the empire of the Zaques, founded by Bochica or Idacanzas, the high priest of Iraca, in New Grenada.) and the mountains of Cayenne towards the Atlantic, and those which stretch from the Andes of New Spain towards the Alleghenies.
Nations advanced in civilization, of which we discover traces on the banks of lake Teguyo and in the Casas grandes of the Rio Gila, might have sent some tribes eastward into the open countries of the Missouri and the Ohio, where the climate differs little from that of New Mexico; but in South America, where the great flux of nations has continued from north to south, those who had long enjoyed the mild temperature of the back of the equinoctial Cordilleras no doubt dreaded a descent into burning plains bristled with forests, and inundated by the periodical swellings of rivers. It is easy to conceive how much the force of vegetation, and the nature of the soil and climate, within the torrid zone, embarra.s.sed the natives in regard to migration in numerous bodies, prevented settlements requiring an extensive s.p.a.ce, and perpetuated the misery and barbarism of solitary hordes.
The feeble civilization introduced in our days by the Spanish monks pursues a retrograde course. Father Gili relates that, at the time of the expedition to the boundaries, agriculture began to make some progress on the banks of the Orinoco; and that cattle, especially goats, had multiplied considerably at Maypures. We found no goats, either in the mission or in any other village of the Orinoco; they had all been devoured by the tigers. The black and white breeds of pigs only, the latter of which are called French pigs (puercos franceses), because they are believed to have come from the Caribbee Islands, have resisted the pursuit of wild beasts. We saw with much pleasure guacamayas, or tame macaws, round the huts of the Indians, and flying to the fields like our pigeons. This bird is the largest and most majestic species of parrot with naked cheeks that we found in our travels. It is called in Marativitan, cahuei. Including the tail, it is two feet three inches long. We had observed it also on the banks of the Atabapo, the Temi, and the Rio Negro. The flesh of the cahuei, which is frequently eaten, is black and somewhat tough. These macaws, whose plumage glows with vivid tints of purple, blue, and yellow, are a great ornament to the Indian farm-yards; they do not yield in beauty to the peac.o.c.k, the golden pheasant, the pauxi, or the alector. The practice of rearing parrots, birds of a family so different from the gallinaceous tribes, was remarked by Columbus. When he discovered America he saw macaws, or large parrots, which served as food to the natives of the Caribbee Islands, instead of fowls.
A majestic tree, more than sixty feet high, which the planters call fruta de burro, grows in the vicinity of the little village of Maypures. It is a new species of the unona, and has the stateliness of the Uvaria zeylanica of Aublet. Its branches are straight, and rise in a pyramid, nearly like the poplar of the Mississippi, erroneously called the Lombardy poplar. The tree is celebrated for its aromatic fruit, the infusion of which is a powerful febrifuge. The poor missionaries of the Orinoco, who are afflicted with tertian fevers during a great part of the year, seldom travel without a little bag filled with frutas de burro. I have already observed that between the tropics, the use of aromatics, for instance very strong coffee, the Croton cascarilla, or the pericarp of the Unona xylopioides, is generally preferred to that of the astringent bark of cinchona, or of Bonplandia trifolatia, which is the Angostura bark. The people of America have the most inveterate prejudice against the employment of different kinds of cinchona; and in the very countries where this valuable remedy grows, they try (to use their own phrase) to cut off the fever, by infusions of Scoparia dulcis, and hot lemonade prepared with sugar and the small wild lime, the rind of which is equally oily and aromatic.
The weather was unfavourable for astronomical observations. I obtained, however, on the 20th of April, a good series of corresponding alt.i.tudes of the sun, according to which the chronometer gave 70 degrees 37 minutes 33 seconds for the longitude of the mission of Maypures; the lat.i.tude was found, by a star observed towards the north, to be 5 degrees 13 minutes 57 seconds; and by a star observed towards the south, 5 degrees 13 minutes 7 seconds. The error of the most recent maps is half a degree of longitude and half a degree of lat.i.tude. It would be difficult to relate the trouble and torments which these nocturnal observations cost us. Nowhere is a denser cloud of mosquitos to be found. It formed, as it were, a particular stratum some feet above the ground, and it thickened as we brought lights to illumine our artificial horizon. The inhabitants of Maypures, for the most part, quit the village to sleep in the islets amid the cataracts, where the number of insects is less; others make a fire of brushwood in their huts, and suspend their hammocks in the midst of the smoke.
We spent two days and a half in the little village of Maypures, on the banks of the great Upper Cataract, and on the 21st April we embarked in the canoe we had obtained from the missionary of Carichana. It was much damaged by the shoals it had struck against, and the carelessness of the Indians; but still greater dangers awaited it. It was to be dragged over land, across an isthmus of thirty-six thousand feet; from the Rio Tuamini to the Rio Negro, to go up by the Ca.s.siquiare to the Orinoco, and to repa.s.s the two raudales.
When the traveller has pa.s.sed the Great Cataracts, he feels as if he were in a new world, and had overstepped the barriers which nature seems to have raised between the civilized countries of the coast and the savage and unknown interior. Towards the east, in the bluish distance, we saw for the last time the high chain of the Cunavami mountains. Its long, horizontal ridge reminded us of the Mesa of the Brigantine, near c.u.mana; but it terminates by a truncated summit. The Peak of Calitamini (the name given to this summit) glows at sunset as with a reddish fire. This appearance is every day the same. No one ever approached this mountain, the height of which does not exceed six hundred toises. I believe this splendour, commonly reddish but sometimes silvery, to be a reflection produced by large plates of talc, or by gneiss pa.s.sing into mica-slate. The whole of this country contains granitic rocks, on which here and there, in little plains, an argillaceous grit-stone immediately reposes, containing fragments of quartz and of brown iron-ore.
In going to the embarcadero, we caught on the trunk of a hevea* (* One of those trees whose milk yields caoutchouc.) a new species of tree-frog, remarkable for its beautiful colours; it had a yellow belly, the back and head of a fine velvety purple, and a very narrow stripe of white from the point of the nose to the hinder extremities.
This frog was two inches long, and allied to the Rana tinctoria, the blood of which, it is a.s.serted, introduced into the skin of a parrot, in places where the feathers have been plucked out, occasions the growth of frizzled feathers of a yellow or red colour. The Indians showed us on the way, what is no doubt very curious in that country, traces of cartwheels in the rock. They spoke, as of an unknown animal, of those beasts with large horns, which, at the time of the expedition to the boundaries, drew the boats through the valley of Keri, from the Rio Toparo to the Rio Cameji, to avoid the cataracts, and save the trouble of unloading the merchandize. I believe these poor inhabitants of Maypures would now be as much astonished at the sight of an ox of the Spanish breed, as the Romans were at the sight of the Lucanian oxen, as they called the elephants of the army of Pyrrhus.
We embarked at Puerto de Arriba, and pa.s.sed the Raudal de Cameji with some difficulty. This pa.s.sage is reputed to be dangerous when the water is very high; but we found the surface of the river beyond the raudal as smooth as gla.s.s. We pa.s.sed the night in a rocky island called Piedra Raton, which is three-quarters of a league long, and displays that singular aspect of rising vegetation, those cl.u.s.ters of shrubs, scattered over a bare and rocky soil, of which we have often spoken.
On the 22nd of April we departed an hour and a half before sunrise.
The morning was humid but delicious; not a breath of wind was felt; for south of Atures and Maypures a perpetual calm prevails. On the banks of the Rio Negro and the Ca.s.siquiare, at the foot of Cerro Duida, and at the mission of Santa Barbara, we never heard that rustling of the leaves which has such a peculiar charm in very hot climates. The windings of rivers, the shelter of mountains, the thickness of the forests, and the almost continual rains, at one or two degrees of lat.i.tude north of the equator, contribute no doubt to this phenomenon, which is peculiar to the missions of the Orinoco.
In that part of the valley of the Amazon which is south of the equator, but at the same distance from it, as the places just mentioned, a strong wind always rises two hours after mid-day. This wind blows constantly against the stream, and is felt only in the bed of the river. Below San Borja it is an easterly wind; at Tomependa I found it between north and north-north-east; it is still the same breeze, the wind of the rotation of the globe, but modified by slight local circ.u.mstances. By favour of this general breeze you may go up the Amazon under sail, from Grand Para as far as Tefe, a distance of seven hundred and fifty leagues. In the province of Jaen de Bracamoros, at the foot of the western declivity of the Cordilleras, this Atlantic breeze rises sometimes to a tempest.
It is highly probable that the great salubrity of the Amazon is owing to this constant breeze. In the stagnant air of the Upper Orinoco the chemical affinities act more powerfully, and more deleterious miasmata are formed. The insalubrity of the climate would be the same on the woody banks of the Amazon, if that river, running like the Niger from west to east, did not follow in its immense length the same direction, which is that of the trade-winds. The valley of the Amazon is closed only at its western extremity, where it approaches the Cordilleras of the Andes. Towards the east, where the sea-breeze strikes the New Continent, the sh.o.r.e is raised but a few feet above the level of the Atlantic. The Upper Orinoco first runs from east to west, and then from north to south. Where its course is nearly parallel to that of the Amazon, a very hilly country (the group of the mountains of Parima and of Dutch and French Guiana) separates it from the Atlantic, and prevents the wind of rotation from reaching Esmeralda. This wind begins to be powerfully felt only from the confluence of the Apure, where the Lower Orinoco runs from west to east in a vast plain open towards the Atlantic, and therefore the climate of this part of the river is less noxious than that of the Upper Orinoco.
In order to add a third point of comparison, I may mention the valley of the Rio Magdalena, which, like the Amazon, has one direction only, but unfortunately, instead of being that of the breeze, it is from south to north. Situated in the region of the trade-winds, the Rio Magdalena has the stagnant air of the Upper Orinoco. From the ca.n.a.l of Mahates as far as Honda, particularly south of the town of Mompox, we never felt the wind blow but at the approach of the evening storms.
When, on the contrary, you proceed up the river beyond Honda, you find the atmosphere often agitated. The strong winds that are ingulfed in the valley of Neiva are noted for their excessive heat. We may be at first surprised to perceive that the calm ceases as we approach the lofty mountains in the upper course of the river, but this astonishment ends when we recollect that the dry and burning winds of the Llanos de Neiva are the effect of descending currents. The columns of cold air rush from the top of the Nevados of Quindiu and of Guanacas into the valley, driving before them the lower strata of the atmosphere. Everywhere the unequal heating of the soil, and the proximity of mountains covered with perpetual snow, cause partial currents within the tropics, as well as in the temperate zone. The violent winds of Neiva are not the effect of a repercussion of the trade-winds; they rise where those winds cannot penetrate; and if the mountains of the Upper Orinoco, the tops of which are generally crowned with trees, were more elevated, they would produce the same impetuous movements in the atmosphere as we observe in the Cordilleras of Peru, of Abyssinia, and of Thibet. The intimate connection that exists between the direction of rivers, the height and disposition of the adjacent mountains, the movements of the atmosphere, and the salubrity of the climate, are subjects well worthy of attention. The study of the surface and the inequalities of the soil would indeed be irksome and useless were it not connected with more general considerations.
