Then among the bushes there were flocks of the beautiful red-breasted oriole, "Icterus militaris"; but they were unfortu- nately not in good plumage at the time of my visit. The common black vulture is generally to be seen sailing over- head, or seated on some dead tree; and great Muscovy ducks fly past with a rushing sound, like some great aérial machine beating the air violently to support its ponderous body, and offering a striking contrast to the great wood-ibis, which sails along with noiseless wings in flocks of ten ora dozen. In the skirts of forest and in the larger "ilhas," black and spotted jaguars are often found, while pacas, cotias, tatus or armadillos, deer, and other small game are plentiful.
The whole population of the island consists of about forty persons, of whom twenty are slaves, and the remainder free Indians and Negroes in the employ of the proprietors. These are all engaged in attending to the cattle and horses on the island, which vary in number, and were much more numerous three or four years ago; the horses in particular having been almost exterminated by a disease which suddenly appeared among them.

Besides attending to the cattle and horses, they have to build houses and corrals, to hunt alligators for oil, and kill bats, which do great injury to the cattle by sucking their blood night after night. The bats live in holes in trees, where they are killed in considerable numbers, Senhor Leonardo informing me that they had destroyed about seven thousand during the last six months. Many hundreds of cattle are said to have been killed by them in a few years.
The slaves appeared contented and happy, as slaves generally do. Every evening at sunset they came to bid good-night to Senhor Leonardo and myself, a similar salutation taking place when they first met us in the morning. If a negro goes out for the day to any distance, he bids adieu to all he may meet, as
