Another district which forms a definite political and cultural unit is the large island of Kayleula, in the West. The inhabitants are fishermen, canoe-builders, and traders, and undertake big expeditions to the western d’Entrecasteaux islands, trading for betel-nut, sago, pottery and turtle shell in exchange for their own industrial produce.
It has been necessary to give a somewhat detailed description of chieftainship and political divisions, as a firm grasp of the main, political institutions is essential to the understanding of the Kula. All departments of tribal life, religion, magic, economics are interwoven, but the social organisation of the tribe lies at the foundation of everything else. Thus it is essential to bear in mind that the Trobriands form one cultural unit, speaking the same language, having the same institutions, obeying the same laws and regulations, swayed by the same beliefs and conventions. The districts just enumerated, into which the Trobriands are sub-divided, are distinct politically and not culturally; that is, each of them comprises the same kind of natives, only obeying or at least acknowledging their own chief, having their own interests and pursuits, and in case of war each fighting their own fight.
Again, within each district, the several village communities have each a great deal of independence. A village community is represented by a headman, its members make their gardens in one block and under the guidance of their own garden magician; they carry on their own feasts and ceremonial arrangements, mourn their dead in common, and perform, in remembrance of their departed ones, an endless series of food distributions. In all big affairs, whether of the district or of the tribe, members of a village community keep together, and act in one group.

Right across the political and local divisions cut the totemic clans, each having a series of linked totems, with a bird as principal one.6 The members of these four clans are scattered over the whole tribe of Boyowa, and in each village community, members of all four are to be found, and even in every house, there are at least two classes represented, since a husband must be of a different clan from his wife and children. There is a certain amount of solidarity within the clan, based on the very vague feeling of
