In addition to the fruitfulness of the land, noxious animals are rarely to be met with. Even the rabbits, they say, were not indigenous, but that a male and female having been introduced by some one from the opposite continent, from thence the whole stock sprung, which formerly was so great a nuisance that even houses and trees were overturned, [being undermined] by their warrens, and the inhabitants were compelled, as we have related, to resort for refuge to the Romans. However, at the present day the facility with which these animals are taken, prevents them from doing injury, consequently those who possess land cultivate it with advantage. These [islands] are on this side of what are called the Pillars of Hercules.
