I Could Have Fancied Myself Transported To The North Of Europe, To The Ridge Of The Mountains Of Gneiss And Granite Between Freiberg And Marienberg In Saxony.

The cladonias appeared to me to be identical with the Lichen rangiferinus, the L. pixidatus, and the L. polymorphus of Linnaeus.

After having passed the rapids of Guarinuma, the Indians showed us in the middle of the forest, on our right, the ruins of the mission of Mendaxari, which has been long abandoned. On the east bank of the river, near the little rock of Kemarumo, in the midst of Indian plantations, a gigantic bombax* (* Bombax ceiba.) attracted our curiosity. We landed to measure it; the height was nearly one hundred and twenty feet, and the diameter between fourteen and fifteen. This enormous specimen of vegetation surprised us the more, as we had till then seen on the banks of the Atabapo only small trees with slender trunks, which from afar resembled young cherry-trees. The Indians assured that these small trees do not form a very extensive group. They are checked in their growth by the inundations of the river; while the dry grounds near the Atabapo, the Temi, and the Tuamini, furnish excellent timber for building. These forests do not stretch indefinitely to the east and west, toward the Cassiquiare and the Guaviare; they are bounded by the open savannahs of Manuteso, and the Rio Inirida. We found it difficult in the evening to stem the current, and we passed the night in a wood a little above Mendaxari; which is another granitic rock traversed by a stratum of quartz. We found in it a group of fine crystals of black schorl.

On the 29th, the air was cooler. We had no zancudos, but the sky was constantly clouded, and without stars. I began to regret the Lower Orinoco. We still advanced but slowly from the force of the current, and we stopped a great part of the day to seek for plants. It was night when we arrived at the mission of San Balthasar, or, as the monks style it, the mission of la divina Pastora de Balthasar de Atabapo. We were lodged with a Catalonian missionary, a lively and agreeable man, who displayed in these wild countries the activity that characterises his nation. He had planted a garden, where the fig-tree of Europe was found in company with the persea, and the lemon-tree with the mammee. The village was built with that regularity which, in the north of Germany, and in protestant America, we find in the hamlets of the Moravian brethren; and the Indian plantations seemed better cultivated than elsewhere. Here we saw for the first time that white and fungous substance which I have made known by the name of dapicho and zapis.* (* These two words belong to the Poimisano and Paragini tongues.) We immediately perceived that it was analogous to india-rubber; but, as the Indians made us understand by signs, that it was found underground, we were inclined to think, till we arrived at the mission of Javita, that the dapicho was a fossil caoutchouc, though different from the elastic bitumen of Derbyshire. A Pomisano Indian, seated by the fire in the hut of the missionary, was employed in reducing the dapicho into black caoutchouc. He had spitted several bits on a slender stick, and was roasting them like meat. The dapicho blackens in proportion as it grows soft, and becomes elastic. The resinous and aromatic smell which filled the hut, seemed to indicate that this coloration is the effect of the decomposition of a carburet of hydrogen, and that the carbon appears in proportion as the hydrogen burns at a low heat. The Indian beat the softened and blackened mass with a piece of brazil-wood, formed at one end like a club; he then kneaded the dapicho into balls of three or four inches in diameter, and let it cool. These balls exactly resemble the caoutchouc of the shops, but their surface remains in general slightly viscous. They are used at San Balthasar in the Indian game of tennis, which is celebrated among the inhabitants of Uruana and Encaramada; they are also cut into cylinders, to be used as corks, and are far preferable to those made of the bark of the cork-tree.

This use of caoutchouc appeared to us the more worthy notice, as we had been often embarrassed by the want of European corks. The great utility of cork is fully understood in countries where trade has not supplied this bark in plenty. Equinoctial America nowhere produces, not even on the back of the Andes, an oak resembling the Quercus suber; and neither the light wood of the bombax, the ochroma, and other malvaceous plants, nor the rhachis of maize, of which the natives make use, can well supply the place of our corks. The missionary showed us, before the Casa de los Solteros (the house where the young unmarried men reside), a drum, which was a hollow cylinder of wood, two feet long and eighteen inches thick. This drum was beaten with great masses of dapicho, which served as drumsticks; it had openings which could be stopped by the hand at will, to vary the sounds, and was fixed on two light supports. Savage notions love noisy music; the drum and the botuto, or trumpet of baked earth, in which a tube of three or four feet long communicates with several barrels, are indispensable instruments among the Indians for their grand pieces of music.

The night of the 30th of April was sufficiently fine for observing the meridian heights of x of the Southern Cross, and the two large stars in the feet of the Centaur. I found the latitude of San Balthasar 3 degrees 14 minutes 23 seconds. Horary angles of the sun gave 70 degrees 14 minutes 21 seconds for the longitude by the chronometer. The dip of the magnetic needle was 27.8 degrees (cent div). We left the mission at a late hour in the morning, and continued to go up the Atabapo for five miles; then, instead of following that river to its source in the east, where it bears the name of Atacavi, we entered the Rio Temi.
