[106] Naturalisation Act, 1870, § 2.
Besides acquisition by occupation, possession for a certain length of time, labour, voluntary transfer, and inheritance, there are instances in which ownership in a thing directly follows from ownership in another thing. It is a general rule that the owner of an object also owns what develops from or is produced by it.[107] The owner of a cow owns her calf, the owner of a tree its fruits, the owner of a piece of land anything growing on it, at least if no labour has been necessary for its production. Ownership in land also gives a certain right to the wild animals which are found there. Among the Fantis, for instance, if anybody kills game on another person’s land, its proprietor is entitled to the shoulder or a quarter of such game.[108] In this connection we have further to notice the mode of acquisition which the Roman jurists called accessio. When that which belongs to one person is so intermixed with the property of another, that either it cannot be separated at all, or cannot be separated without inflicting damage out of proportion to the gain, the owner of the principal becomes the owner of the accessory, though, as a rule, he would have to pay compensation for it.[109]
