excessive rainfall, an analogous ceremony takes place to stop it. Old men then enter into a veritable frenzy,[1276] while the cries uttered by the crowd are really painful to hear.[1277]
Spencer and Gillen describe, under the name of Intichiuma, a ceremony which may well have the same object and the same origin as the preceding ones: a physical torture is applied to make an animal species multiply. Among the Urabunna, there is one clan whose totem is a variety of snake called wadnungadni. This is how the chief of the clan proceeds, to make sure that these snakes may never be lacking. After having been decorated, he kneels down on the ground, holding his arms straight out. An assistant pinches the skin of his right arm between his fingers, and the officiant forces a pointed bone five inches long through the fold thus formed. This self-mutilation is believed to produce the desired result.[1278] An analogous rite is used among the Dieri to make the wild-hens lay: the operators pierce their scrotums.[1279] In certain of the Lake Eyre tribes, men pierce their ears to make yams reproduce.[1280]
But these partial or total famines are not the only plagues which may fall upon a tribe. Other events happen more or less periodically which menace, or seem to menace, the existence of the group. This is the case, for example, with the southern lights. The Kurnai believe that this is a fire lighted in the heavens by the great god Mungan-ngaua; therefore, whenever they see it, they are afraid that it may spread to the earth and devour them, so a great effervescence results in the camp. They shake a withered hand, to which the Kurnai attribute various virtues, and utter such cries as "Send it away; do not let us be burned." At the same time, the old men order an exchange of wives, which always indicates a great excitement.[1281] The same sexual licence is mentioned among the Wiimbaio whenever a plague appears imminent, and especially in times of an epidemic.[1282]
Under the influence of these ideas, mutilations and the shedding of blood are sometimes considered an efficient means of curing maladies. If an accident happens to a child among the Dieri, his relations beat themselves on the head with clubs or boomerangs until the blood flows down over their faces. They believe that by this process, they relieve the child of the suffering.[1283] Elsewhere, they imagine that they can obtain the same end by means of a supplementary totemic ceremony.[1284] We may connect with these the example already given of a ceremony celebrated specially to efface the effects of a ritual fault.[1285] Of course there are neither wounds nor blows nor physical suffering of any sort in these two latter cases, yet the rite does not differ in nature from the others: the end sought is always the turning aside of an evil or the expiation of a fault by means of an extraordinary ritual prestation.
