(M170) But when a savage names himself after an animal, calls it his brother, and refuses to kill it, the animal is said to be his totem. Accordingly in the tribes of South-Eastern Australia which we have been considering the bat and the owl, the emu-wren and the superb warbler, may properly be described as totems of the sexes. But the assignation of a totem to a sex is comparatively rare, and has hitherto been discovered nowhere but in Australia. Far more commonly the totem is appropriated not to a sex, but to a clan, and is hereditary either in the male or female line. The relation of an individual to the clan totem does not differ in kind from his relation to the sex totem; he will not kill it, he speaks of it as his brother, and he calls himself by its name. Now if the relations are similar, the explanation which holds good of the one ought equally to hold good of the other. Therefore the reason why a clan revere a particular species of animals or plants (for the clan totem may be a plant) and call themselves after it, would seem to be a belief that the life of each individual of the clan is bound up with some one animal or plant of the species, and that his or her death would be the consequence of killing that particular animal, or destroying that particular plant. This explanation of totemism squares very well with Sir George Grey’s definition of a totem or _kobong_ in Western Australia. He says: “A certain mysterious connection exists between a family and its _kobong_, so that a member of the family will never kill an animal of the species to which his _kobong_ belongs, should he find it asleep; indeed he always kills it reluctantly, and never without affording it a chance to escape. This arises from the family belief that some one individual of the species is their nearest friend, to kill whom would be a great crime, and to be carefully avoided. Similarly, a native who has a vegetable for his _kobong_ may not gather it under certain circumstances, and at a particular period of the year.”(587) Here it will be observed that though each man spares all the animals or plants of the species, they are not all equally precious to him; far from it, out of the whole species there is only one which is specially dear to him; but as he does not know which the dear one is, he is obliged to spare them all from fear of injuring the one. Again, this explanation of the clan totem harmonizes with the supposed effect of killing one of the totem species. “One day one of the blacks killed a crow. Three or four days afterwards a Boortwa (crow) [_i.e._ a man of the Crow clan] named Larry died. He had been ailing for some days, but the killing of his _wingong_ [totem] hastened his death.”(588) Here the killing of the crow caused the death of a man of the Crow clan, exactly as, in the case of the sex-totems, the killing of a bat causes the death of a Bat-man or the killing of an owl causes the death of an Owl-woman.
