James George Frazer,
The Golden Bough: A Study in Magic and Religion…
“ While they are smouldering and sending forth volumes of smoke across the fields, young men kindle broom-stumps, soaked in pitch, at the bonfires and then, brandishing the stumps, which emit showers of sparks, they chase one another or dance with the girls round the burning pile. Shots, too, are fired, and shouts raised. The fire, the smoke, the shots, and the shouts are all intended to scare away the witches, who are let loose on this witching day, and who would certainly work harm to the crops and the cattle, if they were not deterred by these salutary measures. ”
