The exchange of these two classes of vaygu’a, of the armshells and the necklaces, constitutes the main act of the Kula. This exchange is not done freely, right and left, as opportunity offers, and where the whim leads. It is subject indeed to strict limitations and regulations. One of these refers to the sociology of the exchange, and entails that Kula transactions can be done only between partners. A man who is in the Kula—for not everyone within its district is entitled to carry it on—has only a limited number of people with whom he does it. This partnership is entered upon in a definite manner, under fulfilment of certain formalities, and it constitutes a life-long relationship. The number of partners a man has varies with his rank and importance. A commoner in the Trobriands would have a few partners only, whereas a chief would number hundreds of them. There is no special social mechanism to limit the partnership of some people and extend that of the others, but a man would naturally know to what number of partners he was entitled by his rank and position. And there would be always the example of his immediate ancestors to guide him. In other tribes, where the distinction of rank is not so pronounced, an old man of standing, or a headman of a hamlet or village would also have hundreds of Kula associates, whereas a man of minor importance would have but few.
Two Kula partners have to kula with one another, and exchange other gifts incidentally; they behave as friends, and have a number of mutual duties and obligations, which vary with the distance between their villages and with their reciprocal status. An average man has a few partners near by, as a rule his relations-in-law or his friends, and with these partners, he is generally on very friendly terms. The Kula partnership is one of the special bonds which unite two men into one of the standing relations of mutual exchange of gifts and services so characteristic of these natives. Again, the average man will have one or two chiefs in his or in the neighbouring districts with whom he kulas. In such a case, he would be bound to
