Amongst the Warramunga especially, it is no uncommon thing to find that the greater number of women in any camp are prohibited from speaking. In the case of the widows, mothers, and mothers-in-law, this ban extends over the whole period of mourning, and even at the expiration of this the women will sometimes voluntarily remain silent, preferring to use the gesture language, in which they become most remarkably proficient. At the present moment there is a very old woman in the camp at Tennant Creek who has not spoken for more than twenty-five years, and who will probably, before very long, pass to her grave without ever uttering another word.2
