England, in one part of this reign, was so troubled by wolves, which, driven out of the open country, hid themselves in the mountains of Wales when they were not attacking travellers and animals, that the tribute payable by the Welsh people was forgiven them, on condition of their producing, every year, three hundred wolves’ heads. And the Welshmen were so sharp upon the wolves, to save their money, that in four years there was not a wolf left.
