When leaving their kampong to take part in an expedition to New Guinea the Penihings heard the cry of a bird called tarratjan, and requested the lieutenant in charge to wait four days. He replied, naturally, that the Company (government) does not employ birds in making decisions, and while the Dayaks offered no further objection they declared to him that one of them would surely die. According to my informant it so happened that before arriving at the island one man died. If at such a time a large tree should be seen falling, he said, then they would like to give up the trip to New Guinea entirely, but being afraid of the Company they go, notwithstanding the warning. If a head-hunting party sees a large tree fall, the expedition is abandoned, and no young men who took part can ever join another venture of the same kind. Old and experienced men, after the lapse of a year, may resume operations. In case of meeting a centipede a head-hunting expedition must return immediately to the kampong, and for four years no such enterprise may be undertaken. The purposes of head-hunting are manifold. The slain man is believed to change into a servant and assistant in the next life. When a chief dies it becomes an essential duty to provide him with heads, which are deposited on his grave as sacrifices, and the souls of which serve him in the next life. Heads taken for the benefit of kampong people are hung in the house of the kapala to counteract misfortune and to confer all manner of benefits. An important point is that the presence of the heads from other tribes, or rather of the souls residing in them, compels evil antohs to depart. A kampong thus becomes purified, free from disease. The killing of a fowl is not sufficient to accomplish this; that of a pig helps a little, a water-buffalo more, but to kill a man and bring the head makes the kampong completely clean. With the Katingans a head hanging in the house is considered a far better guardian than the wooden figures called kapatongs, which play an important part in the life of that tribe. Any fear of resentment on the part of the liao (departed soul) residing in the head is precluded by their belief that the Katingan antoh gave him the order to watch. "If no heads are brought in there will be much illness, poor harvest, little fruit, fish will not come up the river as far as our kampong, and the dogs will not care to pursue pigs," I was told by a Penihing who had taken part in a head-hunt and served his sentence in Soerabaia. "But are not people angry at losing their heads?" I asked him. "No," he answered, "we give the heads food on their arrival and every month afterward, and make fire every evening to keep them warm. If they feel cold, then they get angry." The man who has taken a head is considered a hero by the women, and if unmarried is certain to secure a desirable wife, but it is erroneous to assert that the taking of a head was or is a necessary condition to marriage.
