day; indeed the men in authority whom travellers dub chiefs or sheikhs are in fact the actual or potential rain-makers of the tribe or community. Each of them is believed to be animated by the spirit of a great rain-maker, which has come down to him through a succession of rain-makers; and in virtue of this inspiration a successful rain-maker enjoys very great power and is consulted on all important matters. Yet in spite, or rather in virtue, of the high honour in which he is held, no Dinka rain-maker is allowed to die a natural death of sickness or old age; for the Dinka believe that if such an untoward event were to happen, the tribe would suffer from disease and famine, and the herds would not yield their increase. So when a rain-maker feels that he is growing old and infirm, he tells his children that he wishes to die. Among the Agar Dinka a large grave is dug and the rain-maker lies down in it, surrounded by his friends and relatives. From time to time he speaks to the people, recalling the past history of the tribe, reminding them how he has ruled and advised them, and instructing them how they are to act in the future. Then, when he has concluded his admonition, he bids them cover him up. So the earth is thrown down on him as he lies in the grave, and he soon dies of suffocation. Such, with minor variations, appears to be the regular end of the honourable career of a rain-maker in all the Dinka tribes. The Khor-Adar Dinka told Dr. Seligman that when they have dug the grave for their rain-maker they strangle him in his house. The father and paternal uncle of one of Dr. Seligman's informants had both been rain-makers and both had been killed in the most regular and orthodox fashion. Even if a rain-maker is quite young he will be put to death should he seem likely to perish of disease. Further, every precaution is taken to prevent a rain-maker from dying an accidental death, for such an end, though not nearly so serious a matter as death from illness or old age, would be sure to entail sickness on the tribe. As soon as a rain-maker is killed, his valuable spirit is supposed to pass to a suitable successor, whether a son or other near blood relation.
In the Central African kingdom of Bunyoro down to recent years custom required that as soon as the king fell seriously ill or began to break up from age, he should die by his own hand; for, according to an old prophecy, the throne would pass away from the dynasty if ever the king were to die a natural death. He killed himself by draining a poisoned cup. If he faltered or were too ill to ask for the cup, it was his wife's duty to administer the poison. When the king of Kibanga, on the Upper Congo, seems near his end, the sorcerers put a rope round his neck, which they draw gradually tighter till he dies. If the king of Gingiro happens to be wounded in war, he is put to death by his comrades, or, if they fail to kill him, by his kinsfolk, however hard he may beg for mercy. They say they do it that he may not die by the hands of his enemies. The Jukos are a heathen tribe of the Benue River, a great tributary of the Niger. In their country "the town of Gatri is ruled by a king who is elected by the
