13 It has been doubted whether a wild animal becomes your property immediately you have wounded it so severely as to be able to catch it. Some have thought that it becomes yours at once, and remains so as long as you pursue it, though it ceases to be yours when you cease the pursuit, and becomes again the property of any one who catches it: others have been of opinion that it does not belong to you till you have actually caught it. And we confirm this latter view, for it may happen in many ways that you will not capture it. 14 Bees again are naturally wild; hence if a swarm settles on your tree, it is no more considered yours, until you have hived it, than the birds which build their nests there, and consequently if it is hived by some one else, it becomes his property. So too any one may take the honeycombs which bees may chance to have made, though, of course, if you see some one coming on your land for this purpose, you have a right, to forbid him entry before that purpose is effected. A swarm which has flown from your hive is considered to remain yours so long as it is in your sight and easy of pursuit: otherwise it belongs to the first person who catches it. 15 Peafowl too and pigeons are naturally wild, and it is no valid objection that they are used to return to the same spots from which they fly away, for bees do this, and it is admitted that bees are wild by nature; and some people have deer so tame that they will go into the woods and yet habitually come back again, and still no one denies that they are naturally wild. With regard, however, to animals which have this habit of going away and coming back again, the rule has been established that they are deemed yours so long as they have the intent to return: for if they cease to have this intention they cease to be yours, and belong to the first person who takes them; and when they lose the habit they seem also to have lost the intention of returning. 16 Fowls and geese are not naturally wild, as is shown by the fact that there are some kinds of fowls and geese which we call wild kinds. Hence if your geese or fowls are frightened and fly away, they are considered to continue yours wherever they may be, even though you have lost sight of them; and any one who keeps them intending thereby to make a profit is held guilty of theft. 17 Things again which we capture from the enemy at once become ours by the law of nations, so that by this rule even free men become our slaves, though, if they escape from our power and return to their own people, they recover their previous condition. 18 Precious stones too, and gems, and all other things found on the seashore, become immediately by natural law the property of the finder: 19 and by the same law the young of animals of which you are the owner become your property also.
