This image is carried to a distance by a runner and thrown away. He is attended by men, who shout at the top of their voices, brandish swords, and fire guns, all to frighten the demons and drive them far from human habitations.(507) (M155) At Old Calabar on the coast of Guinea, the devils and ghosts are, or used to be, publicly expelled once in two years. Among the spirits thus driven from their haunts are the souls of all the people who died since the last lustration of the town. About three weeks or a month before the expulsion, which according to one account takes place in the month of November, rude effigies representing men and animals, such as crocodiles, leopards, elephants, bullocks, and birds, are made of wicker-work or wood, and being hung with strips of cloth and bedizened with gew-gaws, are set before the door of every house. About three o’clock in the morning of the day appointed for the ceremony the whole population turns out into the streets, and proceeds with a deafening uproar and in a state of the wildest excitement to drive all lurking devils and ghosts into the effigies, in order that they may be banished with them from the abodes of men. For this purpose bands of people roam through the streets knocking on doors, firing guns, beating drums, blowing on horns, ringing bells, clattering pots and pans, shouting and hallooing with might and main, in short making all the noise it is possible for them to raise. The hubbub goes on till the approach of dawn, when it gradually subsides and ceases altogether at sunrise. By this time the houses have been thoroughly swept, and all the frightened spirits are supposed to have huddled into the effigies or their fluttering drapery. In these wicker figures are also deposited the sweepings of the houses and the ashes of yesterday’s fires. Then the demon-laden images are hastily snatched up, carried in tumultuous procession down to the brink of the river, and thrown into the water to the tuck of drums. The ebb-tide bears them away seaward, and thus the town is swept clean of ghosts and devils for another two years. This biennial expulsion of spirits goes by the name of _Ndok_, and the effigies by which it is effected are called _Nabikem_ or _Nabikim_.(508)
