The patient reader will have observed the difficulty experienced alike by scientific explorers and missionaries in expounding this idea in its varied forms and applications. The difficulty has not arisen wholly from its strangeness. It is due in large part to its want of clarity. The savage {62} himself does not know; he has rarely had occasion, and still more rarely inclination, to reflect on his beliefs. He has had no schools of science or philosophy to think out his thoughts for him. Hence they are ill defined; like clouds in the sky, they take first one shape and then another. Yet those very clouds, by comparison with the formless vapour from whence they have been condensed, are continents of solidity and definiteness. Although the idea of _orenda_, or _mana_, may not receive everywhere the same explicit recognition, it is implied in the customs and beliefs of mankind throughout the world. It underlies the practice of Taboo. We have had already occasion to notice this in reference to the _mana_ of Maori chiefs. In the population of Madagascar there is a large, perhaps a predominant Polynesian element. When a Malagasy sticks up in his field a figure or scarecrow to keep off robbers, it is not that they may dread prosecution with all the rigour of the law, though that may be the result if they are caught. What is threatened is sickness, mysteriously induced by the power of the owner of the field, or by the power which he has caused to be conjured into the scarecrow.[62.1] A Samoan in the same way suspends to a cocoa-nut palm a small figure of a shark made with a leaf of the tree; it is notice to the robber that he will be inevitably devoured by a white shark the next time he goes to fish.[62.2] Similar practices prevail in the Melanesian islands.[62.3] Taboo has obtained a very prominent position in the social order and government of Polynesian communities. It is {63} from them that the word has been adopted into English parlance, and adapted to a sense near akin to that of another interesting word--to _boycott_. But it is not only in Polynesia and the neighbouring islands of Melanesia that the dread of a mysterious _mana_ is found, or that it leads to prohibitions and abstinences often very burdensome. It is unnecessary to adduce examples of the taboos on women, practically universal in the lower culture at certain times. The Siberian Chukchi, whose fire has gone out on the cold and timberless tundra, cannot borrow fire from his neighbour, for “the fire of a strange family is regarded as infectious and as harbouring strange spirits. Fear of pollution extends also to all objects belonging to a strange hearth, to the skins of the tent and the sleeping room, and even to the keepers and worshippers of strange penates. The Chukchi from far inland, who travel but little, when they come to a strange territory fear to sleep in tents or to eat meat cooked on a strange fire, preferring to sleep in the open air and to
