Of the palms alone, upwards of a hundred species are found in these forests. These supply the Indian with nearly all he wants to support existence. Their fruit, or pith, or crowns, furnish him with an abundance of food. He builds his hut and floors it with their wood, and thatches it with their leaves. From the trunks of some species he forms his canoes, of different sizes. He obtains from them oil, cord, thread, wine—or a beverage which answers the purpose—wax, mats, baskets, arrows for his sumpitan or bow, and numberless other articles. Pure, clear oils are made from some of the nuts and palm fruits; while many palms yield a fibrous material admirably suited for cordage, being singularly elastic and resistant.
From the curious candella-tree,—called by the Spaniards arbol de la manteca, by the Indians cuajo,—he obtains tallow for candles and excellent oil for lamps, and a beverage which is made from its fruit.
The cow-tree supplies a milk in appearance like that of the animal from which it takes its name, but thicker. On analysing this product, it is found to consist of water, animal
milk, and wax as pure as that obtained from bees. By dipping cotton in the liquid, too, candles can be made.
In the hotter regions grows the bajuco d’agua, which supplies the place of wells and fountains,—each yard of it affording a pint of water. High up on the mountainside, in the regions of icy wastes, called the paramos, grows the frailejou, which yields a pure turpentine, and assists to warm the human body. Of the palms, a few only can be described. There is the cocoa-nut palm, with its swollen bulb-like stem when young, its tall straight trunk when full-grown, its cluster of heavy fruit, its long plume-like drooping flower; the coccoeiro, with its slighter trunk and pendent branches of small berry-like fruit; the palmetto, with its tender succulent bud on the summit of the stem, used as a vegetable, and proving an excellent substitute for cabbage; the thorny icari, or cari—a variety of fan-palm. Its spiny stems and leaves, which cut like razors, make it difficult to approach. Its bunches of bright chestnut-brown fruit hang from between the leaves which form its crown, each bunch about a foot in length, massive and compact, like a large cluster of black Hamburg grapes.
The syagrus palm has a greenish fruit, not unlike the olive in appearance, which hangs in large pendent bunches just below the leaves. The fruit resembles somewhat that of the bread-tree, but is more slender and cylindrical in form.
The leaves of different kinds of palms are used for thatching the Indian huts, the curua palm among others. When young, they grow closely round the mid-rib attached to the axis by a few fibres only, so that when the mid-rib is held up they hang from it like so many straw-coloured ribbons. With these leaves both the walls and roofs are covered. The mid-rib, which is strong, and sometimes four or five yards long, is set across to serve as a support, and bind down the pendent leaves. Such a thatch will last for years, and is an excellent protection from rain as well as sun.
The Indian furnishes himself with cups and vessels of all sorts from the cuieira-tree (Crescentia cajeput). It is of immense size, the fruit being like a gourd. It is spherical, of a light green shining surface, and grows from the size of an apple to that of the largest melon. It is filled with a soft white pulp, easily removed when the fruit is cut in halves. The rind is then allowed to dry. Cups and basins of various sizes are made from it, which the Indians adorn with a variety of brilliant colours.
One of the staple productions of the Upper Amazon is the guarana. It is a trailing plant, a sort of vine; when full-grown, about eight feet high, and bearing a bean the size of a coffee-bean, two being enclosed in each envelope. This bean, after being roasted, is pounded in a small quantity of water till it becomes compact, and, when dry, is about the colour of chocolate. It is then grated with the rough tongue of the piraracu, and when mixed with sugar and water makes a refreshing beverage. It is said to have an excellent effect when administered in cases of diarrhoea.
