(M92) The expulsion of evils, from being occasional, tends to become periodic. It comes to be thought desirable to have a general riddance of evil spirits at fixed times, usually once a year, in order that the people may make a fresh start in life, freed from all the malignant influences which have been long accumulating about them. Some of the Australian blacks annually expelled the ghosts of the dead from their territory. The ceremony was witnessed by the Rev. W. Ridley on the banks of the River Barwan. “A chorus of twenty, old and young, were singing and beating time with boomerangs.... Suddenly, from under a sheet of bark darted a man with his body whitened by pipeclay, his head and face coloured with lines of red and yellow, and a tuft of feathers fixed by means of a stick two feet above the crown of his head. He stood twenty minutes perfectly still, gazing upwards. An aboriginal who stood by told me he was looking for the ghosts of dead men. At last he began to move very slowly, and soon rushed to and fro at full speed, flourishing a branch as if to drive away some foes invisible to us. When I thought this pantomime must be almost over, ten more, similarly adorned, suddenly appeared from behind the trees, and the whole party joined in a brisk conflict with their mysterious assailants.... At last, after some rapid evolutions in which they put forth all their strength, they rested from the exciting toil which they had kept up all night and for some hours after sunrise; they seemed satisfied that the ghosts were driven away for twelve months. They were performing the same ceremony at every station along the river, and I am told it is an annual custom.”(341)
