Thus, if I am right, the essential feature in all the three great initiatory rites of the Australians is the removal of a vital part of the person which shall serve as a link between two successive incarnations by preparing for the novice a new body to house his spirit when its present tabernacle shall have been worn out. Now, if there is any truth in this suggestion, we should expect to find that measures to ensure reincarnation are also taken at death and burial. This seems in fact to be done. For, in the first place, the practice of pouring the blood of kinsmen and kinswomen into the grave is obviously susceptible of this explanation, since, in accordance with the Australian usages which I have cited, the blood might well be thought {p102} to strengthen the feeble ghost for a new birth. The same may be said of the Australian custom of depositing hair with the dead,​[341] for it is a common notion that the hair is the seat of strength.​[342] Again, it has been a rule with some Australian tribes to bury their dead on the spot where they were born.​[343] This was very natural if they desired the dead man to be born again. Further, the common Australian practice of depositing the dead in trees​[344] may, in some cases at least, have been designed to facilitate rebirth; for trees are often the places in which the souls of the dead reside, and from which they come forth to be born again in human shape. Thus the Unmatjera and Kaitish tribes bury very aged women and decrepit old men in the ground; but the bodies of children, young women, and men in the prime of life are laid on platforms among the boughs of trees; and in regard to children we are definitely told that this is done in the hope that “before very long its spirit may come back again and enter the body of a woman—in all probability that of its former mother.”​[345] Further, the Arunta, who bury their dead, are careful to leave a low depression on one side of the mound, in order that the spirit may pass out and in; and this depression always faces towards the dead man’s or woman’s camping-ground in the _alcheringa_ or remote past, that is, the spot which he or she inhabited in spirit form.​[346] Is not this done to let the spirit rid itself of its decaying tabernacle and repair to the place where in due time it will find a new and better body? In this connexion the final burial rites in the Binbinga, Anula, and Mara tribes are worthy of remark. Among these people the bones of the dead are, after a series of ceremonies, deposited in a hollow log, on which the dead man’s totem is painted. This log is then placed, with the {p103} bones, in the boughs of a tree beside a pool, so that if possible it overhangs the water. For about three wet seasons the father and son of the deceased, who placed the log there, are alone allowed to eat water-lilies out of that pool, and no woman is permitted to go near the spot. There the bones of the dead man remain till the log rots
