The celebration includes two successive phases. The object of the rites which take place in the first is to assure the prosperity of the animal or vegetable species serving the clan as totem. The means employed for this end may be reduced to two principal types.

It will be remembered that the fabulous ancestors from whom each clan is supposed to be descended, formerly lived on earth and left traces of their passage there. These traces consist especially in stones and rocks which they deposited at certain places, or which were formed at the spots where they entered into the ground. These rocks and stones are considered the bodies or parts of the bodies of the ancestors, whose memory they keep alive; they represent them. Consequently, they also represent the animals and plants which served these same ancestors as totems, for an individual and his totem are only one. The same reality and the same properties are attributed to them as to the actually living plants or animals of the same species. But they have this advantage over these latter, that they are imperishable, knowing neither sickness nor death. So they are like a permanent immutable and ever-available reserve of animal and vegetable life. Also, in a certain number of cases, it is this reserve that they annually draw upon to assure the reproduction of the species.

Here, for example, is how the Witchetty grub clan, at Alice Springs, proceeds at its Intichiuma.[1107]

On the day fixed by the chief, all the members of the totemic group assemble in the principal camp. The men of the other totems retire to a distance;[1108] for among the Arunta, they are not allowed to be present at the celebration of the rite, which has all the characteristics of a secret ceremony. An individual of a different totem, but of the same phratry, may be invited to be present, as a favour; but this is only as a witness. In no case can he take an active part.

After the men of the totem have assembled, they leave the camp, leaving only two or three of their number behind. They advance in a profound silence, one behind another, all naked, without arms and without any of their habitual ornaments. Their attitude and their pace are marked with a religious gravity: this is because the act in which they are taking part has an exceptional importance in their eyes. Also, until the end of the ceremony they are required to observe a rigorous fast.

The country which they traverse is all filled with souvenirs left by the glorious ancestors. Thus they arrive at a spot where a huge block of quartz is found, with small round stones all around it. This block represents the witchetty grub as an adult. The Alatunja strikes it with a sort of wooden tray called apmara,[1109] and at the same time he intones a chant, whose object is to invite the animal to lay eggs. He proceeds in the same fashion with the stones which are regarded as the eggs of the animal and with one of which he rubs the stomach of each assistant. This done, they all descend a little lower, to the foot of a cliff also celebrated in the myths of the Alcheringa, at the base of which is another stone, also representing the witchetty grub. The Alatunja strikes it with his apmara; the men accompanying him do so as well, with branches of a gum-tree which they have gathered on the way, all of which goes on in the midst of chants renewing the invitation previously addressed to the animal. About ten different spots are visited in turn, some of which are a mile or more from the others. At each of them there is a stone at the bottom of a cave or hole, which is believed to represent the witchetty grub in one of his aspects or at one of the phases of his existence, and upon each of these stones, the same ceremonies are repeated.

The meaning of the rite is evident. When the Alatunja strikes the sacred stones, it is to detach some dust. The grains of this very holy dust are regarded as so many germs of life; each of them contains a spiritual principle which will give birth to a new being, when introduced into an organism of the same species. The branches with which the assistants are provided serve to scatter this precious dust in all directions; it is scattered everywhere, to accomplish its fecundating work. By this means, they assure, in their own minds, an abundant reproduction of the animal species over which the clans guard, so to speak, and upon which it depends.

The natives themselves give the rite this interpretation. Thus, in the clan of the ilpirla (a kind of "manna"), they proceed in the following manner. When the day of the Intichiuma arrives, the group assembles near a huge rock, about fifty feet high; on top of this rock is another, very similar to the first in aspect and surrounded by other smaller ones. Both represent masses of manna. The Alatunja digs up the ground at the foot of this rock and uncovers a churinga which is believed to have been buried there in Alcheringa times, and which is, as it were, the quintessence of the manna. Then he climbs up to the summit of the higher rock and rubs it, first with the churinga and then with the smaller stones which surround it. Finally, he brushes away the dust which has thus been collected on the surface of the rock, with the branches of a tree; each of the assistants does the same in his turn. Now Spencer and Gillen say that the idea of the natives is that the dust thus scattered will "settle upon the mulga trees and so produce manna." In fact, these operations are accompanied by a hymn sung by those present, in which this idea is expressed.[1110]

With variations, this same rite is found in other societies. Among the Urabunna, there is a rock representing an ancestor of the Lizard clan; bits are detached from it which they throw in every direction, in order to secure an abundant production of lizards.[1111] In this same tribe, there is a sand-bank which mythological souvenirs closely associate with the louse totem. At the same spot are two trees, one of which is called the ordinary louse tree, the other, the crab-louse tree. They take some of this sand, rub it on these trees, throw it about on every side and become convinced that, as a result of this, lice will be born in large numbers.[1112] The Mara perform the Intichiuma of the bees by scattering dust detached from sacred rocks.[1113] For the kangaroo of the plains, a slightly different method is used. They take some kangaroo-dung and wrap it up in a certain herb of which the animal is very fond, and which belongs to the kangaroo totem for this reason. Then they put the dung, thus enveloped, on the ground between two bunches of this herb and set the whole thing on fire. With the flame thus made, they light the branches of trees and then whirl them about in such a way that sparks fly in every direction. These sparks play the same rôle as the dust in the preceding cases.[1114]

In a certain number of clans,[1115] men mix something of their own substance with that of the stone, in order to make the rite more efficacious. Young men open their veins and let streams of blood flow on to the rock. This is the case, for example, in the Intichiuma of the Hakea flower among the Arunta. The ceremony takes place in a sacred place around an equally sacred rock which, in the eyes of the natives, represents Hakea flowers. After certain preliminary operations, "the old leader asks one of the young men to open a vein in his arm, which he does, and allows the blood to sprinkle freely, while the other men continue the singing. The blood flows until the stone is completely covered."[1116] The object of this practice is to revivify the virtues of the stone, after a fashion, and to reinforce its efficacy. It should not be forgotten that the men of the clan are relatives of the plant or animal whose name they bear; the same principle of life is in them, and especially in their blood. So it is only natural that one should use this blood and the mystic germs which it carries to assure the regular reproduction of the totemic species. It frequently happens among the Arunta that when a man is sick or tired, one of his young companions opens his veins and sprinkles him with his blood in order to reanimate him.[1117] If blood is able to reawaken life in a man in this way, it is not surprising that it should also be able to awaken it in the animal or vegetable species with which the men of the clan are confounded.
