(M127) Thus it would seem that the custom of annually banishing witches and demons on a day or night set apart for the purpose has not been confined to Central Europe, but can be traced from Calabria and Rome in the south to the Shetland Islands in the far north. CHAPTER IV. PUBLIC SCAPEGOATS. § 1. The Expulsion of Embodied Evils. (M128) Thus far we have dealt with that class of the general expulsion of evils which I have called direct or immediate. In this class the evils are invisible, at least to common eyes, and the mode of deliverance consists for the most part in beating the empty air and raising such a hubbub as may scare the mischievous spirits and put them to flight. It remains to illustrate the second class of expulsions, in which the evil influences are embodied in a visible form or are at least supposed to be loaded upon a material medium, which acts as a vehicle to draw them off from the people, village, or town. (M129) The Pomos of California celebrate an expulsion of devils every seven years, at which the devils are represented by disguised men. “Twenty or thirty men array themselves in harlequin rig and barbaric paint, and put vessels of pitch on their heads; then they secretly go out into the surrounding mountains. These are to personify the devils. A herald goes up to the top of the assembly-house, and makes a speech to the multitude. At a signal agreed upon in the evening the masqueraders come in from the mountains, with the vessels of pitch flaming on their heads, and with all the frightful accessories of noise, motion, and costume which the savage mind can devise in representation of demons. The terrified women and children flee for life, the men huddle them inside a circle, and, on the principle of fighting the devil with fire, they swing blazing firebrands in the air, yell, whoop, and make frantic dashes at the marauding and bloodthirsty devils, so creating a terrific spectacle, and striking great fear into the hearts of the assembled hundreds of women, who are screaming and fainting and clinging to their valorous protectors. Finally the devils succeed in getting into the assembly-house, and the bravest of the men enter and hold a parley with them. As a conclusion of the whole farce, the men summon courage, the devils are expelled from the assembly-house, and with a prodigious row and racket of sham fighting are chased away into the mountains.”(423) In spring, as soon as the willow-leaves were full grown on the banks of the river, the Mandan Indians celebrated their great annual festival, one of the features of which was the expulsion of the devil. A man, painted black to represent the devil, entered the village from the prairie, chased and frightened the women, and acted the part of a buffalo bull in the buffalo dance, the object of which was to ensure a plentiful supply of buffaloes during the ensuing year. Finally he was chased from the village, the women pursuing him with hisses and gibes,
