A BATCH OF CURIOUS TREES. Of course the escape from danger so imminent, after the first moments were over, produced a sort of reaction in the feelings of all and they During the whole of that day they travelled through a country covered with dense forest. The river was a full half-mile wide, but sometimes there were islands, and then the current became narrowed on each side, so that in passing, the balza almost touched the trees on one side or the other. They saw many kinds of trees growing together, and rarely a large tract covered with any one species of timber, for this, as already remarked, is a peculiarity of the Amazon forest. Many new and curious trees were noticed, of which Don Pablo gave short botanical descriptions to the others, partly to instruct them, and partly to while away the hours. Guapo, at the rudder, listened to these learned lectures, and sometimes added some information of his own about the properties of the trees, and the uses to which they were put by the Indians. This is what is termed the popular part of the science of botany, and, perhaps, it is more important than the mere classification of genera and species, which is usually all the information that you get from the learned and systematic botanists. Among the trees passed to-day was one called the “volador.” This is a large forest tree, with lobed leaves, of a heart-shape. But it is the seeds which are curious, and which give to the tree the odd name of “volador,” or “flier.” These seeds have each a pair of membranaceous and striated wings, which, when the seeds fall, are turned to meet the air at an angle of 45°; and thus a rotatory motion is produced, and the falling seeds turn round and round like little fly-wheels. It is altogether a curious sight when a large volador is shaken in calm weather, to see the hundreds of seeds whirling and wheeling towards the ground, which they take a considerable time in reaching. The volador is not confined to South America, I have seen it in Mexico, and other parts of North America. Another singular tree noticed was a tree of the barberry family known among the Spanish-Americans as barba de tigre, or “tiger's beard.” This name it derives from the fact of its trunk—which is very large and high—being thickly set all over with sharp, branching thorns, that are fancied to resemble the whiskers of the jaguar, or South American “tiger.” A third remarkable tree (or bush) observed was the Bixa orellana, which yields the well-known arnatto dye. This bush is ten or twelve feet in height, and its seeds grow in a burr-like pericarp. These seeds are covered with a reddish pulp, which produces the dye. The mode of making it is simple. The Indian women throw the seeds into a vessel of hot water, and stir them violently for about an hour, until they have taken off the pulp. The water is then poured off, and the It is then “anoto,” sometimes written “arnatto,” sometimes “arnotto,” sometimes “onoto,” and sometimes “anato.” The first is the proper spelling. In Brazil it is called “urucu,” whence the French name “rocou;” and the Peruvians have still another designation for it, “achotÉ.” Of course each tribe of Indians calls it by a separate name. The botanic name, Bixa, is the ancient name by which it was known to the Indians of Hayti, for it is found in most parts of tropical America growing wild, although it is also cultivated. It is an article in great demand among all the Indians of South America, who use it for painting their bodies, and dyeing the cotton cloth of which they make their garments. But these people are very skilful in drawing pigments from plants and trees of many kinds; in fact, their practical chemistry, so far as it relates to dyes and poisons, is quite surprising, and from time to time Guapo pointed out trees that were used by them, for such purposes. One was a climbing plant, whose tendrils reached to the tops of the highest trees. It had beautiful violet-coloured flowers, an inch long, and Don Pablo saw that it was a species of bignonia. Guapo called it “chica.” When in fruit it carries a pod two feet in length, full of winged seeds. But Guapo said it was not from the seeds that the dye was obtained, but from the leaves, which turn red when macerated in water. The colouring matter comes out of the leaves in the form of a light powder, and is then shaped into cakes, which sell among the Indians for the value of a dollar each. This colour has a tinge of lake in it, and is prized even more highly than the anoto. Indeed, red dyes among all savage nations seem to hold a higher value than those of any other colour. Another dye-tree was the “huitoc.” This one is a slender tree, about twenty feet high, with broad leaves shooting out from the stem, and nuts growing at their bases, after the manner of the bread-fruit. These nuts resemble black walnuts, and are of a russet colour outside; but the pulp inside, which produces the huitoc, is of a dark blue, or purple tint. The “wild indigo tree,” was also seen growing in the woods, with a leaf narrow at the base, and broad at the extremity. With these and many other dyes the Indians of the MontaÑa paint their bodies in fantastic modes. So much are they addicted to these customs, that, among the Indians who labour at the missions, some have been known to work nearly a month to procure paint enough to give their body a single coat, and the missionaries have made a merchandise of this gigantic folly. But the paint is not always to be looked upon in the light of a mere folly, or vanity. Sometimes it is used to keep off the “zancudos,” or mosquitoes, so numerous and annoying in these regions. Another singular tree was observed, which Guapo called the “marima,” or “shirt-tree.” The use of this he explained. The tree stands fifty or sixty feet high, with a diameter of from two to three. When they find them of this size, the Indians cut them down, and then separate the trunk into pieces of about three feet long. From these pieces they strip the bark, but without making any longitudinal incision, so that the piece of bark when taken off is a hollow cylinder. It is thin and fibrous, of a red colour, and looks like a piece of coarsely-woven Many other trees were noticed valuable for their fruits, or leaves, or bark, or roots, or their wood. There was the well-known “seringa,” or India-rubber tree; the great courbaril, the “dragon's-blood” tree, not that celebrated tree of the East but one of a different genus from whose white bark flows a red blood-like juice. They saw, also, a species of cinnamon-tree though not the cinnamon of commerce; the large tree that bears the Brazilian nut-meg (the Puxiri); and that one, also, a large forest tree, that bears the nuts known as “Tonka beans,” and which are used in the flavouring of snuff. But of all the trees which our travellers saw on that day, none made such a impression upon them as the “juvia,” or Brazil-nut tree. This tree is not one with a thick trunk; in fact, the largest ones are not three feet in diameter, but it rises to a height of 120 feet. Its trunk is branchless for more than half that height, and the branches then spread out and droop, like the fronds of the palm. They are naked near their bases, but loaded towards the top with tufts of silvery green leaves, each two feet in length. The tree does not blossom until its fifteenth year, and then it bears violet-coloured flowers; although there is another species, the “sapucaya,” which has yellow ones. But it is neither the trunk, nor the branches, nor the leaves, nor yet the flowers of this tree, that render it such an object of curiosity. It is the great woody and spherical pericarps that contain the nuts or fruits that are wonderful. These are often as large as the head of a child, and as hard as the shell of the cocoa-nut! Inside is found a large number—twenty or more—of those triangular-shaped nuts which you may buy at any Italian warehouse under the name of “Brazil-nuts.” |
