"Their food is roots, poultry, or wild fruits. They have no hair on their tails, but a sort of scale or hard crust, as the beavers have. If a cat has nine lives, this creature surely has nineteen; for if you break every bone in their skin, and smash their skull, leaving them quite dead, you may come an hour after and they will be quite gone away, or, perhaps, you may meet them creeping away. They are a very stupid creature, utterly neglecting their safety. They are most like rats than anything. I have for necessity, in the wilderness, eaten of them. Their flesh is very white and well-tasted, but their ugly tails put me out of conceit with that fare. They climb trees as the racoons do. Their fur is not esteemed or used, save that the Indians spin it into girdles and gaiters." Bating the exaggeration about their tenacity of life, and also the error as to their mode of bringing forth, the above account hits off the opossum to a nicety. Lawson might have added that their tails are highly prehensile, and are not only used for suspending them to the branches of trees, but also employed by the female for holding her young upon her back--in which fashion she often carries them about. The flesh of the opossum is not only eatable, but much eaten, and even sought after as a delicacy both by negroes and whites. It is surprising how the number of species of this animal has lately multiplied, under the research of naturalists. Perhaps no creature illustrates more forcibly the folly of setting limits to the species of animals, by simply trusting to the account of those known or described. Over thirty species have been found in America, of which five or six belong to the northern division of the continent. The tropical region is their head-quarters; but they are not confined to the torrid zone, since there are species existing everywhere, from Canada to Chili. Another form of pouched animal that can scarcely be called an opossum is the Yapock of tropical South America. It is a smaller animal than the opossum, aquatic in its habits, and in fact approaches nearer to the family of the water-rats. Of this, too, there are several species. Crossing to Australia we find the pouched animals, as already observed, of several different and very dissimilar genera.
