Swimming is an art soon learned by the children of some primitive races. Mr. Man says of the Andaman Islanders: "With the exception of some of the ê·rem-tâg·a-(inlanders), a knowledge of the art of swimming is common to members of both sexes; the _children_ even, learning almost as soon as they can run, speedily acquire great proficiency" (498. 47). _Language._ With some primitive peoples the ideas as to language-study are pretty much on a par with those prevalent in Europe at a date not so very remote from the present. Of the Káto Pomo Indians of California, Mr. Powers remarks: "Like the Kai Pomo, their northern neighbours, they forbid their squaws from studying languages--which is about the only accomplishment possible to them save dancing--principally, it is believed, in order to prevent them from gadding about and forming acquaintances in neighbouring valleys, for there is small virtue among the unmarried of either sex. But the men pay considerable attention to linguistic studies, and there is seldom one who cannot speak most of the Pomo dialects within a day's journey of his ancestral valley. The chiefs, especially, devote no little care to the training of their sons as polyglot diplomatists; and Robert White affirms that they frequently send them to reside several months with the chiefs of contiguous valleys to acquire the dialects there in vogue" (519. 150). Nevertheless, as Professor Mason observes, among primitive races, woman's share in the "invention, dissemination, conservation, and metamorphosis of language" has been very great, and she has been _par excellence_ the teacher of language, as indeed she is to-day in our schools when expression and _savoir faire_ in speech, rather than deep philological learning and dry grammatical analysis, have been the object of instruction. _Geography._ Much has been said and written about the wonderful knowledge of geography and topography possessed by the Indian of America, and by other primitive peoples as well. The following passage from Mr. Powers' account of the natives of California serves to explain some of this (519. 109):--
