it is still in full vigour and has not yet been impaired by the weakness of disease and old age. In this connexion the particular symptom which is commonly said to seal the king's death-warrant is highly significant; when he can no longer satisfy the passions of his numerous wives, in other words, when he has ceased, whether partially or wholly, to be able to reproduce his kind, it is time for him to die and to make room for a more vigorous successor. Taken along with the other reasons which are alleged for putting the king to death, this one suggests that the fertility of men, of cattle, and of the crops is believed to depend sympathetically on the generative power of the king, so that the complete failure of that power in him would involve a corresponding failure in men, animals, and plants, and would thereby entail at no distant date the entire extinction of all life, whether human, animal, or vegetable. No wonder, that with such a danger before their eyes the Shilluk should be most careful not to let the king die what we should call a natural death of sickness or old age. It is characteristic of their attitude towards the death of the kings that they refrain from speaking of it as death: they do not say that a king has died but simply that he has "gone away" like his divine ancestors Nyakang and Dag, the two first kings of the dynasty, both of whom are reported not to have died but to have disappeared. The similar legends of the mysterious disappearance of early kings in other lands, for example at Rome and in Uganda, may well point to a similar custom of putting them to death for the purpose of preserving their life.
On the whole the theory and practice of the divine kings of the Shilluk correspond very nearly to the theory and practice of the priests of Nemi, the Kings of the Wood, if my view of the latter is correct. In both we see a series of divine kings on whose life the fertility of men, of cattle, and of vegetation is believed to depend, and who are put to death, whether in single combat or otherwise, in order that their divine spirit may be transmitted to their successors in full vigour, uncontaminated by the weakness and decay of sickness or old age, because any such degeneration on the part of the king would, in the opinion of his worshippers, entail a corresponding degeneration on manking, on cattle, and on the crops. Some points in this explanation of the custom of putting divine kings to death, particularly the method of transmitting their divine souls to their successors, will be dealt with more fully in the sequel. Meantime we pass to other examples of the general practice.
The Dinka are a congeries of independent tribes in the valley of the White Nile. They are essentially a pastoral people, passionately devoted to the care of their numerous herds of oxen, though they also keep sheep and goats, and the women cultivate small quantities of millet and sesame. For their crops and above all for their pastures they depend on the regularity of the rains: in seasons of prolonged drought they are said to be reduced to great extremities. Hence the rain-maker is a very important personage among them to
