The ceremonial exchange of the two articles is the main, the fundamental aspect of the Kula. But associated with it, and done under its cover, we find a great number of secondary activities and features. Thus, side by side with the ritual exchange of arm-shells and necklaces, the natives carry on ordinary trade, bartering from one island to another a great number of utilities, often unprocurable in the district to which they are imported, and indispensable there. Further, there are other activities, preliminary to the Kula, or associated with it, such as the building of sea-going canoes for the expeditions, certain big forms of mortuary ceremonies, and preparatory taboos.
The Kula is thus an extremely big and complex institution, both in its geographical extent, and in the manifoldness of its component pursuits. It welds together a considerable number of tribes, and it embraces a vast complex of activities, interconnected, and playing into one another, so as to form one organic whole.
Yet it must be remembered that what appears to us an extensive, complicated, and yet well ordered institution is the outcome of ever so many doings and pursuits, carried on by savages, who have no laws or aims or charters definitely laid down. They have no knowledge of the total outline of any of their social structure. They know their own motives, know the purpose of individual actions and the rules which apply to them, but how, out of these, the whole collective institution shapes, this is beyond their mental range. Not even the most intelligent native has any clear idea of the Kula as a big, organised social construction, still less of its sociological function and implications. If you were to ask him what the Kula is, he would answer by giving a few details, most likely by giving his personal experiences and subjective views on the Kula, but
