‘ the migration track which we can discern as extending from northern 
New Guinea on the one hand and from the southern Philippines on 
the other and identified by the inclusion of Proto-Polynesian speech 
material in the northern islands of the Bismarck Archipelago. 
Of the remnant of the north New Guinea coasting stream the next 
point of diversion occurs at the Dampier-Vitiaz Straits. At this 
point it would be equally convenient for coasting fleets to continue 
southward on the coast of the semi-continental island or to set a 
short course for the channel islands, Long and Umboi (Rook). The 
fleets thus deflected from the New Guinea coast make a landfall at 
the nearest western point of Neu-Pommern, which in itself acts as a 
wedge-conduit for this migration stream. It is equally possible in 
sailing coastwise from this western point to be attracted northward 
along the shore or southward; in fact, we have quite positive evidence 
at the west point (Kilenge and Barriai) of no inconsiderable mixture 
of alien Polynesian linguistic accumulations. The evidence at present 
within reach seems to indicate the north shore of Neu-Pommern as 
the more traveled route, but on the south shore we have sufficient 
evidence (Liebliche-Inseln, Aweleng) that this route also was used. 
These divaricated migrations naturally conmingle at the eastern end 
of Neu-Pommern. It is to be held possible that the Trobriand Islands 
(Kiriwina, Murua, and Nada serving as datum points) may have 
been reached either by fleets passing southerly out of the Dampier- 
Vitiaz exit or from a secondary point of departure on the south coast 
of Neu-Pommern. 
Our particular interest here engages with the possibility of another 
branch of the north coast migrants, those who have not been attracted 
to a deflection to Long and Umboi, but who may be considered as 
having continued along the New Guinea coast of Vitiaz Strait and as 
having thus been led toward the Louisiades. 
All the available data bearing upon this branch of the north-coast 
migrants has been set down upon the accompanying charts (II to V). 
Here we see the score of vocables upon which alone it is possible to 
rest any inquiry into the use of the Vitiaz Strait as a fairway to south- 
eastern New Guinea. Scanty though the material is, it has seemed 
advisable to distinguish it upon the charts as Polynesian and Melane- 
sian, the latter term being employed without precision and as signifying 
no more than that the speech is not Polynesian and not what is at 
present classed as Papuan. In each of these charts the small rectangle 
at the upper margin is employed merely as a symbol indicative that 
the vocable has been more or less definitely established as occurring 
at one or more of the points of linguistic record along the north-coast 
line of migration. The numerals in the legend attached to the various 
lines of tracing refer to the vocabulary items in earlier chapters. 
Having subdivided the material into Polynesian and Melanesian, the
