The owner of a swarm of bees shall have a right to pursue them to another's land, indemnifying the possessor of the latter for the damage. If the owner has not pursued the swarm, or ceases to do so within two consecutive days, the possessor of the land may occupy or retain the same. The owner of domesticated animals may also claim them within twenty days to be counted from their occupation by another person. This period having expired, they shall pertain to him who has caught and kept them. (612a)
