[T]he important point is that with them to possess is to give – and here the natives differ from us notably. A man who owns a thing is naturally expected to share it, to distribute it, to be its trustee and dispenser. And the higher the rank the greater the obligation. A chief will naturally be expected to give food to any stranger, visitor, even loiterer from another end of the village. He will be expected to share any of the betel-nut or tobacco he has about him. So that a man of rank will have to hide away any surplus of these articles which he wants to preserve for his further use. In the Eastern end of New Guinea a type of large basket, with three layers, manufactured in the Trobriands, was specially popular among people of consequence, because one could hide away one's small treasures in the lower compartments. Thus the main symptom of being powerful is to be wealthy, and of wealth is to be generous. Meanness, indeed, is the most despised vice, and the only thing about which the natives have strong moral views, while generosity is the essence of goodness.
