It is possible, as some ethnographists have observed,[48] that intercrural cords and other primitive garments have a physical ground, inasmuch as they protect the most sensitive and unprotected part of the body, especially in women. We may note in this connection the significant remarks of K. von den Steinen, who argues that among Brazilian tribes the object of the _uluri_, etc., is to obtain a maximum of protection for the mucous membrane with a minimum of concealment. Among the Eskimo, as Nansen noted, the corresponding intercrural cord is so thin as to be often practically invisible; this may be noted, I may add, in the excellent photographs of Eskimo women given by Holm. But it is evident that, in the beginning, protection is to little or no extent the motive for attaching foreign substances to the body. Thus the tribes of Central Australia wear no clothes, although they often suffer from the cold. But, in addition to armlets, neck-bands and head-bands, they have string or hair girdles, with, for the women, a very small apron and, for the men, a pubic tassel. The latter does not conceal the organs, being no larger than a coin, and often brilliantly coated with white pipeclay, especially during the progress of _corrobborees_, when a large number of men and women meet together; it serves the purpose of drawing attention to the organs.[49] When Forster visited the unspoilt islanders of the Pacific early in the eighteenth century, he tells us that, though they wore no clothes, they found it necessary to cover themselves with various ornaments, especially on, the sexual parts. "But though their males," he remarks, "were to all appearances equally anxious in this respect with their females, this part of their dress served only to make that more conspicuous which it intended to hide."[50] He adds the significant remark that "these ideas of decency and modesty are only observed at the age of sexual maturity," just as in Central Australia women may only wear aprons after the initiation of puberty. "There are certain things," said Montaigne, "which are hidden in order to be shown;" and there can be no doubt that the contention of Westermarck and others, that ornament and clothing were, in the first place, intended, not to conceal or even to protect the body, but, in large part, to render it sexually attractive, is fully proved.[51] We cannot, in the light of all that has gone before, regard ornaments and clothing as the sole cause of modesty, but the feelings that are thus gathered around the garment constitute a highly important factor of modesty.
