"The stag, and most wild animals ... who suffer much from want in the winter, have no superabundance, nor are in a state to engender till they have recruited themselves during the summer; and it is then the rutting season commences, and during which he exhausts himself so much that he remains the whole winter in a state of langour. His flesh and blood are then so impoverished that worms breed under his skin, which still adds to his misery; and which do not perish till the spring, when he recovers new life from the active nourishment he is abundantly furnished with by the fresh production of the earth."
