andicola, Oreodoxa frigida, Kunthia montana. This last group of palmae montanae, which rises in the Andes of Guanacas nearly to the limit of perpetual snow, was, I believe, entirely unknown before our travels in America. (Nov. Gen. volume 1 page 317; Semanario de Santa Fe de Bogota 1819 Number 21 page 163.) In the season of inundations these clumps of mauritia, with their leaves in the form of a fan, have the appearance of a forest rising from the bosom of the waters. The navigator, in proceeding along the channels of the delta of the Orinoco at night, sees with surprise the summit of the palm-trees illumined by large fires. These are the habitations of the Guaraons (Tivitivas and Waraweties of Raleigh* (* The Indian name of the tribe of Uaraus (Guaraunos of the Spaniards) may be recognized in the Warawety (Ouarauoty) of Raleigh, one of the branches of the Tivitivas. See Discovery of Guiana, 1576 page 90 and the sketch of the habitations of the Guaraons, in Raleghi brevis Descrip. Guianae, 1594 tab 4.)), which are suspended from the trunks of trees. These tribes hang up mats in the air, which they fill with earth, and kindle, on a layer of moist clay, the fire necessary for their household wants. They have owed their liberty and their political independence for ages to the quaking and swampy soil, which they pass over in the time of drought, and on which they alone know how to walk in security to their solitude in the delta of the Orinoco; to their abode on the trees where religious enthusiasm will probably never lead any American stylites.* (* This sect was founded by Simeon Sisanites, a native of Syria. He passed thirty-seven years in mystic contemplation, on five pillars, the last of which was thirty-six cubits high. The sancti columnares attempted to establish their aerial cloisters in the country of Treves, in Germany; but the bishops opposed these extravagant and perilous enterprises. Mosheim, Instit. Hist. Eccles page 192. See Humboldt's Views of Nature (Bohn) pages 13 and 136.) I have already mentioned in another place that the mauritia palm-tree, the tree of life of the missionaries, not only affords the Guaraons a safe dwelling during the risings of the Orinoco, but that its shelly fruit, its farinaceous pith, its juice, abounding in saccharine matter, and the fibres of its petioles, furnish them with food, wine,* and thread proper for making cords and weaving hammocks. (* The use of this moriche wine however is not very common. The Guaraons prefer in general a beverage of fermented honey.) These customs of the Indians of the delta of the Orinoco were found formerly in the Gulf of Darien (Uraba), and in the greater part of the inundated lands between the Guarapiche and the mouths of the Amazon. It is curious to observe in the lowest degree of human civilization the existence of a whole tribe depending on one single species of palm-tree, similar to those insects which feed on
