the main centre of the Kula in its South-Eastern branch, was the small island of Tubetube. And this island was in direct communication with two points to which we have followed the Kula in two directions, starting from the Trobriands; that is, with Dobu and with Woodlark Island.
On points of detail, some queries must be left unsolved. Were the visits returned by the Dobuans and Muruans? According to all probability, yes, but I possess no definite certainty on this point.
Another question is whether the natives of Tubetube were direct partners of Murua or Dobu. We have seen that natives of Kiriwina sail not infrequently to Iwa, Gawa, Kwayawata and even to Woodlark; yet they are not partners (karayta’u) of these natives, but partners once removed (murimuri). I have definite information that the natives of Dobu Island proper and of Du’a’u, who, as we remember are not partners of the Southern Boyowans, stood in direct relation of partnership to the Tubetube. I believe also that the natives of Woodlark made direct Kula exchange with those of Tubetube.
