Note: Do not rely on this information. It is very old.
Damage feasant is where a stranger's beasts are found on another person's land without leave or licence. A man is answerable not only for his own trespass, but for that of his cattle also; for if by his negligent keeping they stray upon the land of another (and much more if he permits or drives them on), and they there tread down his neighbour's hedge, or spoil his corn or his trees, this is a trespass for which the owner must answer in damages. And the law gives the party injured a double remedy in this case by permitting him to distrain the cattle, thus damage feasant, or doing damage, till the owner shall make him satisfaction, or else by leaving him to his remedy by action.
