This, of course, cannot be answered here, as it is a purely biological question; but some such solution of the difficulty seems to me the only one, unless I have missed some very important ethnological clue. I am, as I have said, by no means confident of my researches being final in this matter.
It is amusing to find that the average white resident or visitor to the Trobriands is deeply interested in this subject, and in this subject only, of all the ethnological problems opened to him for consideration. There is a belief prevalent among the white citizens of eastern New Guinea that the Trobrianders are in possession of some mysterious and powerful means of prevention or abortion. This belief is, no doubt, explicable by the remarkable and puzzling facts which we have just been discussing. It is enhanced by insufficient knowledge, and the tendency towards exaggeration and sensationalism so characteristic of the crude European mind. Of insufficient knowledge, I had several examples; for every white man with whom I spoke on the subject would start with the dogmatic assertion that unmarried girls among the Trobrianders never have children, saving those who live with white traders; whereas, as we have seen, illegitimate children are on record.
