It will be well to mention here a few circumstances relative to the large Cayman, which, with the incident just narrated, afford illustrations of the cunning, cowardice and ferocity of this reptile.
I have hitherto had but few occasions of mentioning alligators, although they exist by myriads in the waters of the Upper Amazons. Many different species are spoken of by the natives. I saw only three, and of these two only are common: one, the Jacaré-tinga, a small kind (five feet long when full grown) having a long slender muzzle and a black-banded tail; the other, the Jacaré-uassú, to which these remarks more especially relate; and the third the Jacaré-curúa, mentioned in a former chapter. The Jacaré-uassú, or large Cayman, grows to a length of eighteen or twenty feet, and attains an enormous bulk. Like the turtles, the alligator has its annual migrations, for it retreats to the interior pools and flooded forests in the wet season, and descends to the main river in the dry season. During the months of high water, therefore, scarcely a single individual is to be seen in the main river. In the middle part of the Lower Amazons, about Obydos and Villa Nova, where many of the lakes with their channels of communication with the trunk stream, dry up in the fine months, the alligator buries itself in the mud and becomes dormant, sleeping till the rainy season returns. On the Upper Amazons, where the dry season is never excessive, it has not this habit, but is lively all the year round. It is scarcely exaggerating to say that the waters of the Solimoens are as well-stocked with large alligators in the dry season, as a
