wild pigs, which are still more destructive than the baboons, for they grub up the plants as well as devour the grain; and the watchers drum continually on any metal they have at hand to keep the marauders at bay.(124) In the island of Nias whole fields are sometimes trampled down by these pests between sunset and sunrise. Often the stillness of the serene equatorial night is broken by the strident cries of the watchers of the fields; the sound goes echoing through the wooded valleys for a long time, and here and there a dull grunting tells that the efforts of the sentinels have not been in vain.(125) In Northern Luzon, of the Philippine Archipelago, the rice-fields are similarly exposed to the depredations of wild hogs, and watchers remain on guard day and night in outlooks, sometimes in commodious structures of stone erected for the purpose, who burn fires at night to frighten the animals away.(126) At the beginning of their annual agricultural labours the Banars of Cambodia pray to Yang-Seri that he would be pleased to give them plenty of rice and to prevent the wild boars from eating it up.(127) In Gayo-land, a district of Sumatra, the worst enemies of the rice crops are wild swine and field mice; the whole of the harvest is sometimes destroyed by their inroads.(128) Among the Kai of German New Guinea people who are engaged in the labour of the fields will on no account eat pork. The reason is that pigs, both wild and tame, are the most dangerous foes of the crops; therefore it seems clear to the mind of the Kai that if a field labourer were to eat pork, the flesh of the dead pig in his stomach would attract the living pigs into the field.(129) Perhaps this superstition, based on the principle of sympathetic magic, may explain the aversion to pork which was entertained by some of the agricultural peoples of the Eastern Mediterranean in antiquity. (M27) To people thus familiarised with the ravages of wild boars among the ripe crops the idea might naturally present itself that the animal is either the enemy of the corn-god or perhaps the corn-god himself come in person to enjoy his own despite all the efforts of mankind to keep him out of his rights. Hence we can understand how an agricultural people like the ancient Egyptians may have identified the wild boar either with their corn-god Osiris or with his enemy Typhon. The view which identifies the pig with Osiris derives not a little support from the sacrifice of pigs to him on the very day on which, according to tradition, Osiris himself was killed;(130) for thus the killing of the pig was the annual representation of the killing of Osiris, just as the throwing of the pigs into the caverns at the Thesmophoria was an annual representation of the descent of Persephone into the lower world; and both customs are parallel to the European practice of killing a goat, cock, and so forth, at harvest as a representative of the corn-spirit.
