EASTER ISLAND. 



exterior element, but was lacking in that diffused element which bulks 

 so large in the sister archipelagos. It is clear that it was not a settle- 

 ment which hived off from the Paumotu, the Mangarevan, the Tahiti, 

 or the Marquesas, but one which came driving down upon Rapanui 

 from the outside of the province, that is, from somewhere westward. 



Now, recurring to Tables 32 and 38, we find interesting variety in the 

 exterior identifications ; and before forming the next table it should be 

 stated that the unit percentage throughout the Proto-Samoan column 

 is a true determination only in the case of Mangareva ; in the other lan- 

 guages the true percentage is considerably less than unity; we shall 

 correct this error of statement by setting the sum of the column at 3 

 instead of 4. 



Table 40. 



Here we see that the general Polynesian is more than twice as large 

 in the Rapanui element as in that outside such association, that the 

 Proto-Samoan amounts to less than a quarter, the Tongafiti to less 

 than a half. This points to a source of migration in which the two 

 migration streams had been in such intimacy of contact as to discard a 

 large share of their dialectic differences, or rather, by adoption each 

 from the other of dialectic material, to obliterate the difference. In 

 still further explication it points to a migration far later than the most 

 modern of those which provided Southeast Polynesia with its extra- 

 Rapanui component. 



For the continuance of this comparison we shall need to have the 

 subdivision of the Rapanui itself on the model of Table 38. 



Table 41. 



This gives a curve widely variant from any which this element dis- 

 plays elsewhere in the province ; the nearest curve is that of the Pau- 

 motu, the most remote is that of Tahiti ; Mangareva and the Marquesas, 

 closely alike inter se, are quite wide from Rapanui. 



We next engage upon the qualitative examination of this component, 

 noting that because we now deal with Rapanui in addition to the
