The evidence of institutions confirms the reports about savage belief in magic. The political power of the diviners is very great, as may be observed from the fact that a hereditary chief needs their consecration to make him a chief de jure.(1) In fact, the qualities of the diviner are those which give his sacred authority to the chief. When he has obtained from the diviners all their medicines and information as to the mode of using the isitundu (a magical vessel), it is said that he often orders them to be killed. Now, the chief is so far a medicine-man that he is lord of the air. "The heaven is the chief's," say the Zulus; and when he calls out his men, "though the heaven is clear, it becomes clouded by the great wind that arises". Other Zulus explain this as the mere hyperbole of adulation. "The word of the chief gives confidence to his troops; they say, 'We are going; the chief has already seen all that will happen in his vessel'. Such then are chiefs; they use a vessel for divination."(2) The makers of rain are known in Zululand as "heaven-herds" or "sky-herds," who herd the heaven that it may not break out and do its will on the property of the people. These men are, in fact, (Greek text omitted), "cloud-gatherers," like the Homeric Zeus, the lord of the heavens. Their name of "herds of the heavens" has a Vedic sound. "The herd that herds the lightning," say the Zulus, "does the same as the herder of the cattle; he does as he does by whistling; he says, 'Tshu-i-i-i. Depart and go yonder. Do not come here.'" Here let it be observed that the Zulus conceive of the thunder-clouds and lightning as actual creatures, capable of being herded like sheep. There is no metaphor or allegory about the matter,(3) and no forgetfulness of the original meaning of words. The cloud-herd is just like the cowherd, except that not every man, but only sorcerers, and they who have eaten the "lightning-bird" (a bird shot near the place where lightning has struck the earth), can herd the clouds of heaven. The same ideas prevail among the Bushmen, where the rainmaker is asked "to milk a nice gentle female rain"; the rain-clouds are her hair. Among the Bushmen Rain is a person. Among the Red Indians no metaphor seems to be intended when it is said that "it is always birds who make the wind, except that of the east". The Dacotahs once killed a thunder-bird(4) behind Little Crow's village on the Missouri. It had a face like a man with a nose like an eagle's bill.(5) (1) Callaway, p. 340.
