means of strengthening the constitution, and inducing uncommon longevity. Moreover horses, mules, and oxen are never fatter, or more robust than after feeding on the alfaroba, woods of which abound particularly in Chaco, and the territories of St. Iago, though not even the shadow of such a tree is to be seen in any other part of the immense tracts of Paraguay. The Guaranies, who, being distributed into thirty-two colonies, inhabit a vast extent of country, are destitute of this most wholesome fruit; neither did we ever think fit to plant the alfaroba, which grows so quickly, lest the Abipones, like the other Indians, should turn it to a bad use, and that it should cause drinking-parties and intoxication. Moreover the seeds of the alfaroba, if carelessly scattered in any soil, will certainly, and quickly grow up into trees. The white alfaroba affords not only meat, drink, and medicine, but also excellent materials for building waggons, houses and ships: for its violet-coloured wood is docile, and extremely firm, even under water. The leaves of this tree are small; and from its little pale flowers grow seeds, inclosed in a pod. They ripen in the month of November, and last in the woods till March, or are gradually collected and preserved at home by provident persons. The other species of alfaroba, which the Spaniards call the black, resembles the former in all respects, except that it is smaller and sweeter. Its dusky bark is covered with red spots. The pods, though agreeable to the palate from being extremely sweet, create a roughness in the tongue, if eaten raw too freely, and a difficulty in speaking. I write this on my own experience; for once in a long journey, happening to pluck some of that fruit as I rode along, I was suddenly deprived of the power of speech. Some hours' silence was both the disease and the remedy; the Spaniards who accompanied me being greatly amused at my taciturnity. This kind of alfaroba is more commonly used for food than for drink. Its hulls, when pounded in a mortar, are reduced to a flour, which, after being strained through a sieve, is thrown into a round wooden box, pressed with both hands, and, as it is naturally resinous, forms into bread of itself, and becomes as hard as a stone; for as it abounds in thick rosin, its own dust glues it together. These loaves, which are called _patay_, and are chiefly made in the colonies of St. Iago, and sent to other cities, are taken, not only as food, but as medicine, especially by Europeans labouring under stone or strangury. No one ever doubted that both the black and the white alfaroba, as they have a diuretic property, are of much use, whether taken in a solid or liquid state, to persons in a consumption, or labouring under diseases of the bladder. Some say that spirits of much efficacy in diseases of the kidneys, and in hectic fevers, might, by chemic art, be extracted from both the alfarobas. We must not pass by a third species of
