(M298) The Monumbo of German New Guinea perform masked dances in which the dancers personate supernatural beings or animals, such as kangaroos, dogs, and cassowaries. They consecrate the masks by fumigating them with the smoke of a certain creeper, and believe that by doing so they put life into them. Accordingly they afterwards treat the masks with respect, talk to them as if they were alive, and refuse to part with them to Europeans. Certain of the masks they even regard as guardian spirits and appeal to them for fine weather, help in the chase or in war, and so forth. Every clan owns some masks and the head man of the clan makes all the arrangements for a masquerade. The dances are accompanied by songs of which the words are unintelligible even to the natives themselves.(861) Again, the Kayans of Central Borneo perform masked dances for the purpose of ensuring abundant crops of rice. The actors personate demons, wearing grotesque masks on their faces, their bodies swathed in cumbrous masses of green leaves. “In accordance with their belief that the spirits are more powerful than men, the Kayans assume that when they imitate the form of spirits and play their part, they acquire superhuman power. Hence just as their spirits can fetch back the souls of men, so they imagine that they can lure to themselves the souls of the rice.”(862) (M299) When the Sea Dyaks of Borneo have taken a human head, they hold a Head-feast (_Gawè Pala_) in honour of the war-god or bird-chief Singalang Burong, who lives far away above the sky. At this festival a long liturgy called _mengap_ is chanted, the god is invoked, and is believed to be present in the person of an actor, who poses as the deity and blesses the people in his name. “But the invocation is not made by the human performer in the manner of a prayer direct to this great being; it takes the form of a story, setting forth how the mythical hero Kling or Klieng made a head-feast and fetched Singalang Burong to it. This Kling, about whom there are many fables, is a spirit, and is supposed to live somewhere or other not far from mankind, and to be able to confer benefits upon them. The Dyak performer or performers then, as they walk up and down the long verandah of the house singing the _mengap_, in reality describe Kling’s _Gawè Pala_ [head-feast], and how Singalang Burong was invited and came. In thought the Dyaks identify themselves with Kling, and the resultant signification is that the recitation of this story is an invocation to Singalang Burong, who is supposed to come not to Kling’s house only, but to the actual Dyak house where the feast is celebrated; and he is received by a particular ceremony, and is offered food or sacrifice.” At the close of the ceremony “the performer goes along the house, beginning with the head man, touches each person in it, and pronounces an invocation upon him. In this he is supposed to personate Singalang Burong and his
