In this chapter we have examined the great commotions which from time to time convulse the stony crust of the globe, and scatter desolation in regions favoured by the most precious gifts of nature. An uninterrupted calm prevails in the upper atmosphere; but, to use an expression of Franklin, more ingenious than accurate, thunder often rolls in the subterranean atmosphere, amidst that mixture of elastic fluids, the impetuous movements of which are frequently felt at the surface of the earth. The destruction of so many populous cities presents a picture of the greatest calamities which afflict mankind. A people struggling for independence are suddenly exposed to the want of subsistence, and of all the necessaries of life. Famished and without shelter, the inhabitants are dispersed through the country, and numbers who have escaped from the ruin of their dwellings are swept away by disease. Far from strengthening mutual confidence among the citizens, the feeling of misfortune destroys it; physical calamities augment civil discord; nor does the aspect of a country bathed in tears and blood appease the fury of the victorious party.
After the recital of so many calamities, the mind is soothed by turning to consolatory remembrances. When the great catastrophe of Caracas was known in the United States, the Congress, assembled at Washington, unanimously decreed that five ships laden with flour should be sent to the coast of Venezuela; their cargoes to be distributed among the most needy of the inhabitants. The generous contribution was received with the warmest gratitude; and this solemn act of a free people, this mark of national interest, of which the advanced civilization of the Old World affords but few examples, seemed to be a valuable pledge of the mutual sympathy which ought for ever to unite the nations of North and South America.
CHAPTER 1.15.
DEPARTURE FROM CARACAS. MOUNTAINS OF SAN PEDRO AND OF LOS TEQUES. LA VICTORIA. VALLEYS OF ARAGUA.
To take the shortest road from Caracas to the banks of the Orinoco, we should have crossed the southern chain of mountains between Baruta, Salamanca, and the savannahs of Ocumare, passed over the steppes or llanos of Orituco, and embarked at Cabruta, near the mouth of the Rio Guarico. But this direct route would have deprived us of the opportunity of surveying the valleys of Aragua, which are the finest and most cultivated portion of the province; of taking the level of an important part of the chain of the coast by means of the barometer; and of descending the Rio Apure as far as its junction with the Orinoco. A traveller who has the intention of studying the configuration and natural productions of a country is not guided by distances, but by the peculiar interest attached to the regions he may traverse. This powerful motive led us to the mountains of Los Teques, to the hot springs of Mariara, to the fertile banks of the lake of Valencia, and through the immense savannahs of Calabozo to San Fernando de Apure, in the eastern part of the province of Varinas. Having determined on this route, our first direction was westward, then southward, and finally to east-south-east, so that we might enter the Orinoco by the Apure in latitude 7 degrees 36 minutes 23 seconds.
On the day on which we quitted the capital of Venezuela, we reached the foot of the woody mountains which close the valley on the south-west. There we halted for the night, and on the following day we proceeded along the right bank of the Rio Guayra as far as the village of Antimano, by a very fine road, partly scooped out of the rock. We passed by La Vega and Carapa. The church of La Vega rises very picturesquely above a range of hills covered with thick vegetation. Scattered houses surrounded with date-trees seem to denote the comfort of their inhabitants. A chain of low mountains separates the little river Guayra from the valley of La Pascua* (so celebrated in the history of the country) (* Valley of Cortes, or Easter Valley, so called because Diego de Losada, after having defeated the Teques Indians, and their cacique Guaycaypuro, in the mountains of San Pedro, spent the Easter there in 1567, before entering the valley of San Francisco. In the latter place he founded the city of Caracas.), and from the ancient gold-mines of Baruta and Oripoto. Ascending in the direction of Carapa, we enjoy once more the sight of the Silla, which appears like an immense dome with a cliff on the side next the sea. This rounded summit, and the ridge of Galipano crenated like a wall, are the only objects which in this basin of gneiss and mica-slate impress a peculiar character on the landscape. The other mountains have a uniform and monotonous aspect.
A little before reaching the village of Antimano we observed on the right a very curious geological phenomenon. In hollowing the new road out of the rock, two large veins of gneiss were discovered in the mica-slate. They are nearly perpendicular, intersecting all the mica-slate strata, and are from six to eight toises thick. These veins contain not fragments, but balls or spheres of granular diabasis,* formed of concentric layers. (* Ur-grunstein. I remember having seen similar balls filling a vein in transition-slate, near the castle of Schauenstein in the margravate of Bayreuth. I sent several balls from Antimano to the collection of the king of Spain at Madrid.) These balls are composed of lamellar feldspar and hornblende closely commingled. The feldspar approximates sometimes to vitreous feldspar when disseminated in very thin laminae in a mass of granular diabasis, decomposed, and emitting a strong argillaceous smell. The diameter of the spheres is very unequal, sometimes four or eight inches, sometimes three or four feet; their nucleus, which is more dense, is without concentric layers, and of a very dark green hue, inclining to black. I could not perceive any mica in them; but, what is very remarkable, I found great quantities of disseminated garnets. These garnets are of a very fine red, and are found in the grunstein only. They are neither in the gneiss, which serves as a cement to the balls, nor in the mica-slate, which the veins traverse. The gneiss, the constituent parts of which are in a state of considerable disintegration, contains large crystals of feldspar; and, though it forms the body of the vein in the mica-slate, it is itself traversed by threads of quartz two inches thick, and of very recent formation. The aspect of this phenomenon is very curious: it appears as if cannon-balls were embedded in a wall of rock. I also thought I recognized in these same regions, in the Montana de Avila, and at Cabo Blanco, east of La Guayra, a granular diabasis, mixed with a small quantity of quartz and pyrites, and destitute of garnets, not in veins, but in subordinate strata in the mica-slate. This position is unquestionably to be found in Europe in primitive mountains; but in general the granular diabasis is more frequently connected with the system of transition rocks, especially with a schist (ubergangs-thonschiefer) abounding in beds of Lydian stone strongly carburetted, of schistose jasper,* (Kieselschiefer.) ampelites,* (Alaunschiefer.) and black limestone.
Near Antimano all the orchards were full of peach-trees loaded with blossom. This village, the Valle, and the banks of the Macarao, furnish great abundance of peaches, quinces, and other European fruits for the market of Caracas. Between Antimano and Ajuntas we crossed the Rio Guayra seventeen times. The road is very fatiguing; yet, instead of making a new one, it would perhaps be better to change the bed of the river, which loses a great quantity of water by the combined effects of filtration and evaporation. Each sinuosity forms a marsh more or less extensive. This loss of water is to be regretted in a province, nearly all the cultivated portions of which are extremely dry. The rains are much less frequent and less violent in this place than in the interior of New Andalusia, at Cumanacoa, and on the banks of the Guarapiche. Many of the mountains of Caracas enter the region of the clouds; but the strata of primitive rocks dip at an angle of 70 or 80 degrees, and generally to northwest, so that the waters are either lost in the interior of the earth, or gush out in copious springs not southward but northward of the mountains of the coast of Niguatar, Avila, and Mariara. The rising of the gneiss and mica-slate strata to the south appears to me to explain in a considerable degree the extreme humidity of the coast. In the interior of the province we meet with portions of land, two or three leagues square, in which there are no springs; consequently sugar-cane, indigo, and coffee, grow only in places where running waters can be made to supply artificial irrigation during very dry weather. The early colonists imprudently destroyed the forests. Evaporation is enormous on a stony soil surrounded with rocks, which radiate heat on every side. The mountains of the coast, like a wall, extending east and west from Cape Codera toward Point Tucacas, prevent the humid air of the shore (that is to say, those inferior strata of the atmosphere resting immediately on the sea, and dissolving the largest proportion of water) from penetrating to the islands. There are few openings, few ravines, which, like those of Catia or of Tipe, lead from the coast to the high longitudinal valleys, and there is no bed of a great river, no gulf allowing the sea to flow inland, spreading moisture by abundant evaporation. In the eighth and tenth degrees of latitude, in regions where the clouds do not, as it were, skim the surface of the soil, many trees are stripped of their leaves in the months of January and February; not by the sinking of the temperature as in Europe, but because the air at this period, the most distant from the rainy season, nearly attains its maximum of dryness. Only those plants which have very tough and glossy leaves resist this absence of humidity. Beneath the fine sky of the tropics the traveller is struck with the almost hibernal aspect of the country; but the freshest verdure again appears when he reaches the banks of the Orinoco, where another climate prevails; and the great forests preserve by their shade a certain quantity of moisture in the soil, by sheltering it from the devouring heat of the sun.
Beyond the small village of Antimano the valley becomes much narrower. The river is bordered with Lata, a fine gramineous plant with distich leaves, which sometimes reaches the height of thirty feet.* (* G. saccharoides.) Every hut is surrounded with enormous trees of persea,* (* Laurus persea (alligator pear).) at the foot of which the aristolochiae, paullinia, and other creepers vegetate. The neighbouring mountains, covered with forests, seem to spread humidity over the western extremity of the valley of Caracas. We passed the night before our arrival at Las Ajuntas at a sugar-cane plantation. A square house (the hacienda or farm of Don Fernando Key-Munoz) contained nearly eighty negroes; they were lying on skins of oxen spread upon the ground. In each apartment of the house were four slaves: it looked like a barrack. A dozen fires were burning in the farm-yard, where people were employed in dressing food, and the noisy mirth of the blacks almost prevented us from sleeping. The clouds hindered me from observing the stars; the moon appeared only at intervals. The aspect of the landscape was dull and uniform, and all the surrounding hills were covered with aloes. Workmen were employed at a small canal, intended for conveying the waters of the Rio San Pedro to the farm, at a height of more than seventy feet. According to a barometric calculation, the site of the hacienda is only fifty toises above the bed of the Rio Guayra at La Noria, near Caracas.
The soil of these countries is found to be but little favourable to the cultivation of the coffee-tree, which in general is less productive in the valley of Caracas than was imagined when the first plantations were made near Chacao. The finest coffee-plantations are now found in the savannah of Ocumare, near Salamanca, and at Rincon, in the mountainous countries of Los Mariches, San Antonio Hatillo, and Los Budares. The coffee of the three last mentioned places, situated eastward of Caracas, is of a superior quality; but the trees bear a smaller quantity, which is attributed to the height of the spot and the coolness of the climate. The greater plantations of the province of Venezuela (as Aguacates, near Valencia and Rincon) yield in good years a produce of three thousand quintals.
