"The principle of chastity," said Forster, of his experiences in the South Sea Islands in their unspoilt state, "we found in many families exceedingly well understood. I have seen many fine women who, with a modesty mixed with politeness, refuse the greatest and most tempting offers made them by our forward youths; often they excuse themselves with a simple _tirra-tano_, 'I am married,' and at other times they smiled and declined it with _epia_, 'no.' ... Virtuous women hear a joke without emotion, which, amongst us, might put some men to the blush. Neither austerity and anger, nor joy and ecstasy is the consequence, but sometimes a modest, dignified, serene smile spreads itself over their face, and seems gently to rebuke the uncouth jester." (J.R. Forster, _Observations made During a Voyage Round the World_, 1728, p. 392.) Captain Cook, at Tahiti, in 1769, after performing Divine service on Sunday, witnessed "Vespers of a very different kind. A young man, near six feet high, performed the rites of Venus with a little girl about eleven or twelve years of age, before several of our people and a great number of the natives, without the least sense of its being indecent or improper, but, as it appeared, in perfect conformity to the custom of the place. Among the spectators were several women of superior rank, who may properly be said to have assisted at the ceremony; for they gave instructions to the girl how to perform her part, which, young as she was, she did not seem much to stand in need of." (J. Hawkesworth, _Account of the Voyages_, etc., 1775, vol. i, p. 469.) At Tahiti, according to Cook, it was customary to "gratify every appetite and passion before witnesses," and it is added, "in the conversation of these people, that which is the principal source of their pleasure is always the principal topic; everything is mentioned without any restraint or emotion, and in the most direct terms, by both sexes." (Hawkesworth, op. cit., vol ii, p. 45.)
