high up in trees the two stones, which stand for clouds, is a way of making the real clouds to mount up in the sky. The Dieri also imagine that the foreskins taken from lads at circumcision have a great power of producing rain. Hence the Great Council of the tribe always keeps a small stock of foreskins ready for use. They are carefully concealed, being wrapt up in feathers with the fat of the wild dog and of the carpet snake. A woman may not see such a parcel opened on any account. When the ceremony is over, the foreskin is buried, its virtue being exhausted. After the rains have fallen, some of the tribe always undergo a surgical operation, which consists in cutting the skin of their chest and arms with a sharp flint. The wound is then tapped with a flat stick to increase the flow of blood, and red ochre is rubbed into it. Raised scars are thus produced. The reason alleged by the natives for this practice is that they are pleased with the rain, and that there is a connexion between the rain and the scars. Apparently the operation is not very painful, for the patient laughs and jokes while it is going on. Indeed, little children have been seen to crowd round the operator and patiently take their turn; then after being operated on, they ran away, expanding their little chests and singing for the rain to beat upon them. However, they were not so well pleased next day, when they felt their wounds stiff and sore. In Java, when rain is wanted, two men will sometimes thrash each other with supple rods till the blood flows down their backs; the streaming blood represents the rain, and no doubt is supposed to make it fall on the ground. The people of Egghiou, a district of Abyssinia, used to engage in sanguinary conflicts with each other, village against village, for a week together every January for the purpose of procuring rain. Some years ago the emperor Menelik forbade the custom. However, the following year the rain was deficient, and the popular outcry so great that the emperor yielded to it, and allowed the murderous fights to be resumed, but for two days a year only. The writer who mentions the custom regards the blood shed on these occasions as a propitiatory sacrifice offered to spirits who control the showers; but perhaps, as in the Australian and Javanese ceremonies, it is an imitation of rain. The prophets of Baal, who sought to procure rain by cutting themselves with knives till the blood gushed out, may have acted on the same principle.
