The ambaỹ, a kind of wild fig, grows pretty high in the course of a few months. The body of the tree is slender, and perforated like an elder; the bark such as is peculiar to figs; and the wood white like that of a birch, but so soft that it may be cut with a knife. It has few boughs, but is adorned with very large leaves, for the lively verdure of which it is greatly commended, as well as for the salubrity of its bark, juice, and leaf, which, applied in various ways, stop running of the reins, too copious discharges, and looseness of the bowels. THE WALNUT. Walnuts, no ways differing from those of our own country, are very common in the woods of Tucuman, but scarce seen in other parts of Paraguay. Their wood is employed in making pistol-cases, handles, and for other kinds of cabinet-maker's work. The nuts are of different sorts, for some are very large, with a soft rind, others quite dwarfish, and with rinds as hard as a stone. THE URUCUỸ. The urucuỹ, which is half shrub half tree, resembles a hazle in the whiteness of its wood, and the blackness of its bark. Its leaves are rather large, and heart-shaped. The flowers, which are composed of five white petals, tinged with red, are about the size of a common rose, but have no scent whatever. For fruit it bears pods, which are green at first, and afterwards red, each containing about forty grains the size of peas, but plain on both sides, and with a white pulp, like the seeds of apples. The surface of them is of a deep bright red, and immediately dyes the hands of all who touch it with that colour. The pods, when ripe, burst open of themselves. These grains, either dry or fresh, supply the place of vermillion: when pounded, and sprinkled with water, they are used by the savages, sometimes for painting their bodies, sometimes for dying or staining cloth, vessels, or other things. This scarlet colour, when a thing is once tinctured with it, adheres pertinaciously, if the grains of the urucuỹ, steeped in water, be mixed with alum or urine. The same grains are thrown into boiling water, and of the colour that settles at the bottom cakes are made, which the women in Europe paint their faces with, and painters and dyers use for other purposes. They are used also both as food and medicine, variously prepared and mixed. Of the bark some weave cables, cords, and ropes, stronger than hempen ones. THE AÑIL, OR INDIGO.
