Again he quotes St. John (p. 143):
Feasts in general are: To make their rice grow well, to cause the forest to abound with wild animals, to enable their dogs and snares to be successful in securing game, to have the streams swarm with fish, to give health and activity to the people themselves, and to insure fertility to their women. All these blessings the possessing and feasting of a fresh head are supposed to be the most efficient means of securing.
He quotes Axel. Dalrymple as follows (p. 141)
The Uru Ais believe that the persons whose heads they take will become their slaves in the next world.
On the same page he quotes others to the same point regarding other tribes of Borneo.
Roth states (p. 163):
From all accounts there can be little doubt that one of the chief incentives to getting heads is the desire to please the women. It may not always have been so and there may be and probably is the natural blood-thirstiness of the animal in man to account for a great deal of the head-taking.
He quotes Mrs. F. F. McDougall in her statement of a Sakaran legend of the origin of head-taking to the effect that the daughter of their great ancestor residing near the Evening Star “refused to marry until her betrothed brought her a present worth her acceptance.” First the young man killed a deer which the girl turned from with disdain; then he killed and brought her one of the great monkeys of the forest, but it did not please her. “Then, in a fit of despair, the lover went abroad and killed the first man he met, and, throwing his victim’s head at the maiden’s feet, he exclaimed at the cruelty she had made him guilty of; but, to his surprise, she smiled and said that now he had discovered the only gift worthy of herself” (p. 163). In the three following pages of his book the author quotes three or four other writers who cite in detail instances wherein heads were taken simply to advance the slayer’s interests with women.
As showing the passion for head-hunting among these people, St. John tells of a young man who, starting alone to get a head from a neighboring tribe, took the head of “an old woman of their own tribe, not very distantly related to the young fellow himself.” When the fact was discovered “he was only fined by the chief of the tribe and the head taken from him and buried” (p. 161).
