THIS remarkable animal was first discovered by the celebrated Captain Cook, in New Holland: and as it was the only quadruped discovered on the inland by the first settlers, they attempted to hunt it with greyhounds. The astonishing leaps it took, however, quite puzzled the colonists, who found it extremely difficult to catch. At first it was supposed that there was only one kind of Kangaroo, but now many species have been discovered, some of them not larger than a rat, and others as big as a calf. Kangaroos live in herds; one, older and larger than the rest, appearing to act as a kind of king. The ears of the Kangaroo are large, and in almost constant motion; it has a hare-lip, and a very small head. The fore legs, or rather paws, are short and weak, with five toes, each ending in a strong curved claw. The hind legs, on the contrary, are very large and strong, but the feet have only four toes, and much weaker claws. The tail is very long and tapering; but is so thick and strong near the body, that it forms a kind of third hind leg, and wonderfully assists the animal in supporting itself in its ordinary upright position. Its leaps are of extraordinary extent, being often from twenty to thirty feet in length, and six or eight feet high. When the animal is attacked, it uses its tail as a powerful instrument of defence, and also scratches violently with its hind feet. It generally sits upright, but brings its fore feet to the ground when it is grazing. It lives entirely on vegetable substances. The most curious part of the Kangaroo is the pouch which the female has in front for carrying her young. It is just below her breast, and the young ones sit there to suck; and even when they are old enough to leave the pouch, take refuge in it whenever they are alarmed. The Kangaroo is easily tamed, and there are many in a tame state in England. In Australia, Kangaroo beef, as it is called, is eaten, and found very nourishing; but it is hard and coarse. The female has generally two young ones at a time, which do not attain their full growth until they are a year old. When a large Kangaroo is pursued by dogs, it generally takes refuge in a pond, where, from the great length of its hind legs and tail, it can stand with its body half out of the water, while the dogs are obliged to swim. Thus the Kangaroo has a decided advantage; for, as each dog approaches him, he seizes it with his fore paws, and holds it under water, shaking it furiously till the dog is almost suffocated, and very glad to sneak off as soon as the Kangaroo lets him go. The female, when pursued and hard-pressed by the dogs, will, while making her bounds, put her fore paws into her pouch, take a young one from it, and throw it as far out of sight as she possibly can. But for this manœuvre, her own life and that of her young one would be sacrificed; whereas, she frequently contrives to escape, and returns afterwards to seek for her offspring.
