A wimble of the same timber was then applied, the end of which they fitted to the hole. But in some parts of the mainland the machinery was different. They used a frame of green wood, of a square form, in the centre of which was an axle-tree. In some places three times three persons, in others three times nine, were required for turning round by turns the axle-tree or wimble. If any of them had been guilty of murder, adultery, theft, or other atrocious crime, it was imagined how to con that the fire would how to con kindle, or that it would be devoid of its usual virtue. So soon as any sparks were emitted by means of the violent friction, they applied a species of agaric which grows on old birch-trees, and is very combustible.
