which appears to fork at the south of Celebes, one traversing that 
interesting island northward into the Philippines, the other established 
by Salayer (a point of peculiar Samoan interest) and Bouton and 
thence forking into the Moluccas. A northerly fork is established by 
Sula on the way to Gilolo; a southerly fork engages with Ceram and 
Buru, islands from which we derive much valuable material. From 
Ceram we derive lines in the northerly direction by way of Mysol 
and Waigiou which bring us to the westerly tip of New Guinea; here 
engage lines from Gilolo and from the Philippines, and here these 
converging lines approximate that course of Polynesian migration along 
the north shore of New Guinea upon which we are all in agreement. 
Here for the present we leave these studies of the great Polynesian 
migration. Some little has been accomplished. We have freed the 
problem from the error and the misleading of the theory of a Malayo- 
Polynesian speech family and a Malayo-Polynesian race. We have 
established the existence of two somewhat widely distinct migrations 
of Polynesians into the Pacific with an interval of centuries. For the 
earlier of these migrations we have traced three courses through 
Melanesia: and into the present Polynesia. The situation of Poly- 
nesia is reasonably clear in its main outlines. Owing to the depopula- 
tion of Melanesia many problems must remain insoluble because of 
the impossibility of acquiring data. In Indonesia much work can 
be done; it is hoped that it will engage the renewed effort of those 
scholars who have devoted their lives to the study of the culture and 
of the speech of the mixture of races whose homes are in the Malay 
Archipelago.
