The opossum, with its prehensile tail, marsupial pouch, and cunning ways, stands alone for its singularity among all the animals of the American continent. Many of the tribe are found in South America; but the Virginian opossum, the size of a full-grown cat, is larger than all its relatives. The head and body measure about twenty-two inches; and the tail, fifteen. It is covered with a light grey hair of wool-like softness, short on the face and body, but long on the legs. The base end of the tail is thick and black, and is covered with small scales. So powerful is this member that the opossum can hold on with it to the bough of a tree, and even when desperately wounded it does not let go. Its face is long and sharpened, the mouth very determined, and armed with numerous sharp teeth. It has thin, naked, round, and blackish ears, edged with a border of white. It has short legs, the feet being armed with claws, and the interior toes of the hind-feet are flat and rounded. It has the power of emitting a disagreeable odour when chased or alarmed. When pursued, it makes for the nearest tree; and should it discover the approach of a hunter and his dogs when already up a tree, instead of taking to flight, it lies close along the branch, endeavouring to hide itself. When moving amidst the boughs, it swings itself from branch to branch by means of its tail; and it may be observed at times hanging down, with its eyes wide open, on the look-out for any birds which may incautiously alight on the bough above, or pass within its grasp. It is very voracious, feeding on small quadrupeds and birds of all sorts; while it does not disdain to prey off a brood of young cotton rats and mice, and devours insects and a variety of reptiles. When unable to find sufficient food in the forest, or too lazy to look for it, it will, without hesitation, make a raid into the farmer's poultry-yard, and carry off or kill his fowls, and eat up any eggs it may find. The opossum does not always indulge in animal diet,--for he climbs fruit-trees to carry off their luscious productions; and for the sake of obtaining maize, of which he is especially fond, he will climb the tallest stems, and bite them across, so as to bring the heavy ear to the ground. He will also clamber to some higher branch, and hang down, in search of the fruit growing on the boughs incapable of bearing his weight.
