There are some Dingoes in the Zoological Gardens, and one would never guess their savageness of disposition from their innocent faces. They are decidedly good-looking Dogs in appearance, but as regards temper they are anything but pleasant animals, although quite tamable if taken young: they are, indeed, often domesticated by the natives, but are never known to attain to those higher qualities which make the thoroughly civilised Dog so valuable. “When Van Diemen’s Land began to be colonised by Europeans, the losses sustained by the settlers by the ravages of the Wild Dogs were almost incredible. The districts infested by these animals were principally those appropriated to Sheep, and there was scarcely a flock that did not suffer. It was in vain to double the number of shepherds, to watch by night and day, or to have fires at every quarter of the field; for these animals would accomplish their object by stratagem or force. One colony lost no fewer than 1,200 Sheep and Lambs in three months; another colony lost 700. “The ravagers were either the native Wild Dogs of the island or those that had escaped from their owners. They seemed to have apportioned the country into different districts, each troop having its allotted range. At length the evil became so great, that a general meeting of the colonists was convened. The concluding sentences of the speech of Lieutenant Hill forcibly express the extent of the evil:--‘The country is free from bushrangers: we are no longer surrounded and threatened by the natives. We have only one enemy left in the field; but that enemy strikes at the root of our welfare, and through him the stream of our prosperity is tainted at its very source.’ The colonists were then few, but they cordially united in the endeavour to extirpate this formidable enemy; and, although the Wild Dog is still found in the interior of the island, he is comparatively seldom seen, and his ravages have nearly ceased.”[121] CHAPTER IX.
