Returning to the two main divisions into the Southern and Northern portion, this latter is occupied by a very homogeneous population, homogeneous both in language and culture, and in the clear recognition of their own ethnic unity. To quote further Professor Seligman, it “is characterised by the absence of cannibalism, which, until put down by the Government, existed throughout the remaining portion of the district; another peculiarity of the Northern Massim is their recognition” in certain districts, though not in all, of chieftains who wield extensive powers (op. cit. p. 7). The natives of that northern area used to practise—I say used because wars are a thing of the past—a type of warfare open and chivalrous, very different from the raids of the Southern Massim. Their villages are built in big compact blocks, and they have storehouses on piles for storing food, distinct from their rather miserable dwellings, which stand directly on the ground and are not raised on piles. As can be seen on the map, it has been necessary to sub-divide this Northern Massim further into three groups, first, that of the Trobriand Islanders, or the Boyowans (the Western Branch); secondly that of the natives
