the poor woman's life, but were soon dislodged by the application of tiger's fat. We have benefited other persons, at various times, with the same remedy. I took care always to have a good supply of a medicine so important, and in such constant request. At the first news of a tiger being slain I hastened to get its fat, which I kept melted in a little vessel; for if raw, it would soon putrefy in so hot a climate. Though the fat of these animals, even when fresh, like the rest of the flesh, exhales a most abominable odour, yet when mixed in water, it is drank by the Abipones with the utmost avidity. In some of the Guarany Reductions, peach leaves are used to expel worms bred by flies. The natives of northern regions will hardly conceive, and natural historians scarce credit the breeding of such dangerous worms from flies; but the Americans witness it daily, and deplore its fatal effects not only on themselves, but on cattle. When we killed a cow or a sheep at sun-rise, the flies have been seen swarming round the flesh; soon after we have found it covered with a kind of whitish seed, and by sun-set the meat became stinking, full of worms, and unfit to be eaten. Those who wish to preserve meat uninjured, should either cut it into very small pieces and dry it in the air, or hang it up in the shade in a net, or wicker basket, so that it may be exposed to the air, without being accessible to flies. Should a horse's back be injured by the hardness of the saddle, or by long riding, the flies will swarm thither as if bidden to a feast, and breed innumerable worms, which mangle the horse, and in a few days destroy him. Blood bursting from an ulcer is a sign that worms are within. In order to remedy this they tie the animal's feet and throw him on the ground, then dig out the worms and matter with a slender stick, and fill up the hole of the ulcer with chewed tobacco-leaves, and cow-dung. This must be repeated for many days. If the animal can lick himself the cure will be surer and quicker. But as this method of healing is accompanied with much trouble and some danger, the Indians, and half Spaniards, who are more lazy than the Indians, had rather see the plain strewed with carcasses, than exert themselves either with their hands or feet. The slothfulness of the shepherds who take care of the estates yearly occasions the loss of many thousand horses, oxen, calves, sheep and mules in Paraguay. New born calves should be examined and rid of the worms, with which they are generally infested; for the flies immediately attack the navel string, and miserably kill them. On which account, if, out of ten thousand calves born yearly on your estate, four thousand remain alive, you have great reason to congratulate yourself, and return thanks to your shepherds.
