Each clan has its totem, which belongs to it alone; two different clans of the same tribe cannot have the same. In fact, one is a member of a clan merely because he has a certain name. All who bear this name are members of it for that very reason; in whatever manner they may be spread over the tribal territory, they all have the same relations of kinship with one another.[217] Consequently, two groups having the same totem can only be two sections of the same clan. Undoubtedly, it frequently happens that all of a clan does not reside in the same locality, but has representatives in several different places. However, this lack of a geographical basis does not cause its unity to be the less keenly felt. In regard to the word totem, we may say that it is the one employed by the Ojibway, an Algonquin tribe, to designate the sort of thing whose name the clan bears.[218] Although this expression is not at all Australian,[219] and is found only in one single society in America, ethnographers have definitely adopted it, and use it to denote, in a general way, the system which we are describing. Schoolcraft was the first to extend the meaning of the word thus and to speak of a "totemic system."[220] This extension, of which there are examples enough in ethnography, is not without inconveniences. It is not normal for an institution of this importance to bear a chance name, taken from a strictly local dialect, and bringing to mind none of the distinctive characteristics of the thing it designates. But to-day this way of employing the word is so universally accepted that it would be an excess of purism to rise against this usage.[221] In a very large proportion of the cases, the objects which serve as totems belong either to the animal or the vegetable kingdom, but especially to the former. Inanimate things are much more rarely employed. Out of more than 500 totemic names collected by Howitt among the tribes of south-eastern Australia, there are scarcely forty which are not the names of plants or animals; these are the clouds, rain, hail, frost, the moon, the sun, the wind, the autumn, the summer, the winter, certain stars, thunder, fire, smoke, water or the sea. It is noticeable how small a place is given to celestial bodies and, more generally, to the great cosmic phenomena, which were destined to so great a fortune in later religious development. Among all the clans of which Howitt speaks, there were only two which had the moon as totem,[222] two the sun,[223] three a star,[224] three the thunder,[225] two the lightning.[226] The rain is a single exception; it, on the contrary, is very frequent.[227]
