But it is more frequently upon the body itself that the totemic mark is stamped: for this is a way of representation within the capacity of even the least advanced societies. It has sometimes been asked whether the common rite of knocking out a young man's two upper teeth at the age of puberty does not have the object of reproducing the form of the totem. The fact is not established, but it is worth mentioning that the natives themselves sometimes explain the custom thus. For example, among the Arunta, the extraction of teeth is practised only in the clans of the rain and of water; now according to tradition, the object of this operation is to make their faces look like certain black clouds with light borders which are believed to announce the speedy arrival of rain, and which are therefore considered things of the same family.[296] This is a proof that the native himself is conscious that the object of these deformations is to give him, at least conventionally, the aspect of his totem. Among these same Arunta, in the course of the rites of sub-incision, certain gashes are cut upon the sisters and the future wife of the novice; scars result from these, whose form is also represented upon a certain sacred object of which we shall speak presently and which is called the _churinga_; as we shall see, the lines thus drawn upon the _churinga_ are emblematic of the totem.[297] Among the Kaitish, the euro is believed to be closely connected with the rain;[298] the men of the rain clan wear little ear-rings made of euro teeth.[299] Among the Yerkla, during the initiation the young man is given a certain number of slashes which leave scars; the number and form of these varies with the totems.[300] An informer of Fison mentions the same fact in the tribes observed by him.[301] According to Howitt, a relationship of the same sort exists among the Dieri between certain arrangements of scars and the water totem.[302] Among the Indians of the North-West, it is a very general custom for them to tattoo themselves with the totem.[303]
