This dreadful beast, which has a head and claws like those of a tiger, which resembles a mastiff in size, has no tail, and possesses singular ferocity, and equal swiftness, is called by the Guaranies aò, a word signifying clothing, but given to this beast because, from its wool, the Guaranies formerly wove themselves garments. They wander gregariously in pools, marshy places, or woods far from the noise of men. But if one of them chance to meet an Indian hunting, his life is as good as gone, unless he can avoid its cruel fangs, by a very swift flight, or by ascending a tree; though when seated on the very highest boughs he cannot be perfectly secure, for as these ferocious animals are incapable of climbing a tree, they will tear it up by the roots with their claws, and when it falls seize hold of their prey. These things the Indians and Spaniards all agree in relating and believing. For my part, after so many journeys on foot, and on horseback, after traversing so many of the woods, plains and marshes of Paraguay, I never saw even the shadow of such a beast. From which I infer that they cannot be very numerous, nor common to the whole province. Would that they were banished from every part of Paraguay! That ferocious animal which writers call _famacosio_, most of us think to differ from the aò in name only. THE CAPIIGUÁRA, OR WATER-PIG. The water-pig inhabits the larger rivers and streams, but not the very largest, although, as it feeds upon grass, it comes out to pasture in the neighbouring plains, not without committing great depredations in the fields. When full grown it resembles a pig of two years old in size, and almost in appearance, except in its vast round head, and the whiskers on its upper lip, which are similar to those of a cat. It has short ears, large, black eyes, a very wide mouth, but rather narrow lips, dusky and very short hair, and no tail. Besides two long, curved tusks, which project from its mouth, it is armed with forty-eight teeth, plain at the top, but hollow beneath. Its feet are like those of a pig; the front ones have four nails, the hind only three. These beasts swim or walk in company, and cross rivers with surprizing expedition. By night they bray like asses, and sometimes alarm travellers unacquainted with America. Their flesh is very like pork, but as it has a fishy taste, is eaten by none but the Indians; though when young they are reckoned a dainty by Europeans even. Capiiguáras may be wounded without difficulty, either with a spear, an arrow, or a ball, but it requires great good fortune to catch them; for on receiving a wound, as they are excellent swimmers and divers, they immediately hide themselves under water, and extract the arrow or spear which is sticking in their flesh. The Abipones, who frequently employ themselves in hunting these animals, after wounding a pig, swim after it and overtake it in the water. The
