While the native cat is the only mischievous carnivorous marsupial on the Australian mainland, Tasmania is possessed of two much larger and more destructive animals, the _Thylacinus_ or 'tiger-wolf,' and the _Sarcophilus_ or 'Tasmanian devil;' the former is nearly as large as a wolf, and is shapely and handsomely marked with stripes on the flanks. The latter is a smaller animal. It has been described as 'an ugly bear-like cat.' It is a thick-set creature, black in colour, with white patches, and its hideous appearance and its untameable ferocity quite entitle it to its popular designation. Both 'tiger' and 'devil' are nocturnal, and both have been so hunted and trapped by the settlers, whose sheep and poultry they killed, as now to be very scarce. Neither has ever been known to attack man. At one time, as geological examination shows, the marsupial 'devil' and his relative were both found in Australia, and the wonder is that they should have so completely disappeared from the scene as they have done. [Illustration: BASS RIVER OPOSSUM.] An animal that stands entirely apart from the marsupials in Australia is the wild dog. The dingo is one of the mysteries. Whence did he come? He is allied to the wild dogs of India, but why should this Indian animal be in Australia--his form on the surface and his bones in ancient deposits--while no other representative of the fauna of the Old World is known? Leaving science to unravel this problem, it may be said of the dingo that he is a good-looking but an ill-behaved animal. He is compared to the sheep-dog, to the wolf, and to the fox, and, in fact, he has a dash of each of these creatures in his appearance. He is about two feet high, is well-proportioned, with erect ears and a bushy tail. He stands firmly on his legs, and shows a good deal of strength in his well-constructed body. His colour varies from a yellowish-tawny to a reddish-brown, growing lighter towards the belly; and the tip of his brush is generally white. He cannot bark like other dogs, but he can howl, and he does howl with a soul-chilling effect. His note is to be likened unto The wolf's long howl from Oonalastra's shore. Campbell's melodious line conveys the idea of misery, and discomfort and uneasiness are engendered when the slumbers of the sleeper in the bush are disturbed by the blood-curdling cry of these breakers of the nocturnal peace. The blacks used to catch the puppies of the wild dog, and then train them to hunt, but they found the European dog sufficient for their purposes, and much more docile and affectionate. As dingoes worry sheep, the first task of a squatter is to get rid of them. When they breed in shelter and a semi-settled district--if they can issue from mallee scrub--a handsome reward is always offered for their heads. In parts of Victoria as much as £2 per head is paid. An engraving of the creature is given on page 181. [Illustration: A KANGAROO BATTUE.]
