which is drawn through this province without coming to shore is 
represented as of the same weight as the Mugula and Sariba lines. 
The Polynesian chart, however, while keeping Suau as of the same 
first importance and Mugula in second place, sets Sariba and Tubetube 
on the same scale of unimportance, and, as in the Melanesian stock, the 
draft from the Gulf Coast which passes without a check beyond the 
South Cape is of the same weight as the Mugula line. Suau on the 
Melanesian chart is of the first importance in speech affinities. Its 
strongest relation is with Sariba; its next is with Mugula, but by a 
considerable interval; with Tavara, its nearest neighbor along the 
coast in the next northern province, as with Tubetube, its direct 
affiliation is at the minimum. ‘The affiliation of Mugula is most 
marked with Suau; it shows a trace with Sariba and Tubetube. 
Sariba, most strongly affiliated with Suau, is very nearly as closely 
in touch with Tubetube; there is a minimum trace in the direction 
of Tavara. ‘Tubetube may be taken as the outpost of the province. 
Its strong relation with Sariba has been noted. It is important to 
note its position as a distributing point of affiliations extending beyond 
this province very strongly marked into the Dentrecasteaux province 
and almost equally into the Louisiades, yet not at all into the East 
Coast province. Sariba extends into the Dentrecasteaux and the 
Louisiades in the same ratio as does Tubetube, but only to the extent 
of half the number of vocables. Suau shows but a trace of extension 
directly to the Louisiades and little more to Dentrecasteaux and the 
east coast. Mukawa exhibits exterior relations in a single instance 
of affiliation on the east coast. The Polynesian chart of this region 
shows somewhat marked difference. Suau remains the principal 
point. Its richest association is still with Sariba; it is joined to 
Mugula and Tavara by lines of equal weight, and that but little short 
of the curve of Suau-Sariba; with Tubetube direct it exhibits but a 
trace of association. Sariba offers much the same picture as on the 
Melanesian chart. Its relations with Suau and Tubetube are in the 
same ratio; its relation with Tavara is less. Tubetube on each chart 
shows no affiliation with the east coast. It affiliates to an equal 
extent with Dentrecasteaux and the Louisiades, and this figure is the 
same as that of its affiliation with Sariba. Sariba shows a trace of 
affiliation with the east coast and with the Louisiades, but a trifle 
more with the Dentrecasteaux. ‘Suau shows with the Dentrecasteaux 
an affiliation quite as strong as with Sariba in its own province, in the 
next degree with the east coast, and only a trace with the Louisiades. 
Mukawa shows a trace of affiliation with the Louisiades. 
East Coast (Charts X and XI).—This province and that of the 
South Cape should be critical of any movement of migration by coast- 
wise voyaging which should bring together streams following the © 
north and the south coasts, respectively, of New Guinea. ‘The proof
