importance, the hospitality of the local demons is invoked. The Kayans make an offering of fowls’ eggs, which must not be bought on the spot, but are carried from the house, sometimes for distances so long that the devotion of the travellers is more apparent than their presents to the spirits of the land. Each boy takes an egg and puts it in a bamboo split at the end into four, while one of the older men calls upon the hills, rocks, trees, and streams to hear him and to witness the offering. Careful to disguise the true nature of the gift, he speaks of it as _ovē_, a yam, using a form of words fixed by usage. ‘Omen bird,’ he shouts into the air, ‘we have brought you these boys. It is on their account only that we have prepared this feast. Harm them not; make things go pleasantly; and they give you the usual offering of a yam. I give this to the country.’ The little ceremony is performed behind the hut where the night is spent, and the boys wait about for the charm to take effect. The custom of the Kenyahs shows the same feeling for the unknown and unseen spirits that are supposed to abound. A fowl’s feathers, one for each boy, are held by an old man, while the youngsters touch his arm. The invocation is quite a powerful example of native rhetoric: ‘Smooth away trouble, ye mystic mountains, hills, valleys, soil, rocks, trees. Shield the lives of the children who have come hither.’ ”(392) When the Toradjas of central Celebes are on a head-hunting expedition and have entered the enemy’s country, they may not eat any fruits which the foe has planted nor any animal which he has reared until they have first committed an act of hostility, as by burning a house or killing a man. They think that if they broke this rule they would receive something of the soul or spiritual essence of the enemy into themselves, which would destroy the mystic virtue of their talismans.(393) It is said that just before Greek armies advanced to the shock of battle, a man bearing a lighted torch stepped out from either side and threw his torch into the space between the hosts. Then they retired unmolested, for they were thought to be sacred to Ares and inviolable.(394) Now some peoples fancy that when they advance to battle the spirits of their fathers hover in the van.(395) Hence fire thrown out in front of the line of battle may be meant to disperse these shadowy combatants, leaving the issue of the fight to be determined by more substantial weapons than ghosts can wield. Similarly the fire which is sometimes borne at the head of an army(396) is perhaps in some cases intended to dissipate the evil influences, whether magical or spiritual, with which the air of the enemy’s country may be conceived to teem.
