THE GIANT KANGAROO. One of the most interesting of mammals is the Kangaroo, a typical Pouched Animal, which is also noteworthy for the disproportionate size and strength of its hind limbs. When moving about on all fours, grazing, it presents an awkward appearance, but it makes rapid progression hy great bounds, using its powerful hind limbs only, after the manner of a Jerboa. When the Kangaroo is at rest it often assumes a perfectly upright position; the tail aiding the two hind legs to form a sort of supporting tripod for the body. When two of these animals tight, which sometimes happens, the weak fore paws prove only ineffective weapons, but the Kangaroo can inflict severe wounds with the sharp claws of its powerful hind feet, sustaining itself meanwhile upon its tail (Macropus giganteus)

The eastern gray kangaroo (Macropus giganteus) is a marsupial found in the eastern third of Australia, with a population of several million. It is also known as the great grey kangaroo and the forester kangaroo. Although a big eastern grey male typically weighs around 66 kg and stands almost 2 m) tall, the scientific name, Macropus giganteus (gigantic large-foot), is misleading: the red kangaroo of the semi-arid inland is larger, weighing up to 90 kg.
