(_d_) The claim to property is instinctive in most animals—claim to a certain territory, or to a nest, or lair, or mate. Each early human pack probably claimed a certain hunting-range; and each family its lair, which it guarded, as our domestic dog guards the house. In Australia “every tribe has its own country, and its boundaries are well known; and they are respected by others”;[67] and the Bushmen, who retained the ancient hunting-life more perfectly than any other known people, are said to have been formerly divided into large tribes with well-defined hunting-grounds.[68] As weapons or other implements, charms, or ornaments came into use, the attitude toward the territory or lair will have been extended to include them; indeed, it seems to be instinctive even in lower Primates. “In the Zoological Gardens,” says Darwin, “a monkey, which had weak teeth, used to break open nuts with a stone; and I was assured by the keepers that, after using the stone, he hid it in the straw, and would not let any other monkey touch it. Here, then, we have the idea of property.”[69] Among the half-wolf train-dogs of Canada, the claims of one to property seem to be recognised by others; for a dog will defend its _cache_ of food against another that ordinarily it fears; and “the bigger dog rarely presses the point.”[70] The utility of keeping the peace within the tribe, no doubt, led to the growth of customs concerning property, and to their protection by the social sanction, and later by the taboo.[71] For taboo cannot be the origin of respect for property or for any custom: it implies a custom already existing, which it protects by the growth of a belief in some magical penalty that is effective even when there are no witnesses. The same utility of order must have established customs of dividing the kill of the pack: later also protected by taboo, as we still see in many savage tribes.
