One Understands Gardening Perfectly; Another Knows How To Prepare Chiza, An Intoxicating Beverage Extracted From The Root Of Cassava; All Appear To Him Alike Clever And Useful.

Sometimes the desire of preserving his wives overcomes in the Indian his inclination to christianity; but most frequently, in his perplexity, the husband prefers submitting to the choice of the missionary, as to a blind fatality.

The Indians, who from May to August take journeys to the east of Esmeralda, to gather the vegetable productions of the mountains of Yumariquin, gave us precise notions of the course of the Orinoco to the east of the mission. This part of my itinerary may differ entirely from the maps that preceded it. I shall begin the description of this country with the granitic group of Duida, at the foot of which we sojourned. This group is bounded on the west by the Rio Tamatama, and on the east by the Rio Guapo. Between these two tributary streams of the Orinoco, amid the morichales, or clumps of mauritia palm-trees, which surround Esmeralda, the Rio Sodomoni flows, celebrated for the excellence of the pine-apples that grow upon its banks. I measured, on the 22nd of May, in the savannah at the foot of Duida, a base of four hundred and seventy-five metres in length; the angle, under which the summit of the mountain appeared at the distance of thirteen thousand three hundred and twenty-seven metres, was still nine degrees. A trigonometric measurement, made with great care, gave me for Duida (that is, for the most elevated peak, which is south-west of the Cerro Maraguaca) two thousand one hundred and seventy-nine metres, or one thousand one hundred and eighteen toises, above the plain of Esmeralda. The Cerro Duida thus yields but little in height (scarcely eighty or one hundred toises) to the summit of St. Gothard, or the Silla of Caracas on the shore of Venezuela. It is indeed considered as a colossal mountain in those countries; and this celebrity gives a precise idea of the mean height of Parima and of all the mountains of eastern America. To the east of the Sierra Nevada de Merida, as well as to the south-east of the Paramo de las Rosas, none of the chains that extend in the same parallel line reach the height of the central ridge of the Pyrenees.

The granitic summit of Duida is so nearly perpendicular that the Indians have vainly attempted the ascent. It is a well-known fact that mountains not remarkable for elevation are sometimes the most inaccessible. At the beginning and end of the rainy season, small flames, which seem to change their place, are seen on the top of Duida. This phenomenon, the existence of which is borne out by concurrent testimony, has caused this mountain to be improperly called a volcano. As it stands nearly alone, it might be supposed that lightning from time to time sets fire to the brushwood; but this supposition loses its probability when we reflect on the extreme difficulty with which plants are ignited in these damp climates. It must be observed also that these flames are said to appear often where the rock seems scarcely covered with turf, and that the same igneous phenomena are visible, on days entirely exempt from storms, on the summit of Guaraco or Murcielago, a hill opposite the mouth of the Rio Tamatama, on the southern bank of the Orinoco. This hill is scarcely elevated one hundred toises above the neighbouring plains. If the statements of the natives be correct, it is probable that some subterraneous cause produces these flames on the Duida and the Guaraco; for they never appear on the lofty neighbouring mountains of Jao and Maraguaca, so often wrapped in electric storms. The granite of the Cerro Duida is full of veins, partly open, and partly filled with crystals of quartz and pyrites. Gaseous and inflammable emanations, either of hydrogen or of naphtha, may pass through these veins. Of this the mountains of Caramania, of Hindookho, and of Himalaya, furnish frequent examples. We saw the appearance of flames in many parts of eastern America subject to earthquakes, even from secondary rocks, as at Cuchivero, near Cumanacoa. The fire shows itself when the ground, strongly heated by the sun, receives the first rains; or when, after violent showers, the earth begins to dry. The first cause of these igneous phenomena lies at immense depths below the secondary rocks, in the primitive formations: the rains and the decomposition of atmospheric water act only a secondary part. The hottest springs of the globe issue immediately from granite. Petroleum gushes from mica-schist; and frightful detonations are heard at Encaramada, between the rivers Arauca and Cuchivero, in the midst of the granitic soil of the Orinoco and the Sierra Parima. Here, as everywhere else on the globe, the focus of volcanoes is in the most ancient soils; and it appears that an intimate connection exists between the great phenomena that heave up and liquify the crust of our planet, and those igneous meteors which are seen from time to time on its surface, and which from their littleness we are tempted to attribute solely to the influence of the atmosphere.

Duida, though lower than the height assigned to it by popular belief, is however the most prominent point of the whole group of mountains that separate the basin of the Lower Orinoco from that of the Amazon. These mountains lower still more rapidly on the north-east, toward the Purunama, than on the east, toward the Padamo and the Rio Ocamo. In the former direction the most elevated summits next to Duida are Cuneva, at the sources of the Rio Paru (one of the tributary streams of the Ventuari), Sipapo, Calitamini, which forms one group with Cunavami and the peak of Umiana. East of Duida, on the right bank of the Orinoco, Maravaca, or Sierra Maraguaca, is distinguished by its elevation, between the Rio Caurimoni and the Padamo; and on the left bank of the Orinoco rise the mountains of Guanaja and Yumariquin, between the Rios Amaguaca and Gehette.
