In Azimba land, Central Africa, H. Crawford Angus, who has spent many years in this part of Africa, writes: "It has been my experience that the more naked the people, and the more to us obscene and shameless their manners and customs, the more moral and strict they are in the matter of sexual intercourse." He proceeds to give a description of the _chensamwali_, or initiation ceremony of girls at puberty, a season of rejoicing when the girl is initiated into all the secrets of marriage, amid songs and dances referring to the act of coition. "The whole matter is looked upon as a matter of course, and not as a thing to be ashamed of or to hide, and, being thus openly treated of and no secrecy made about it, you find in this tribe that the women are very virtuous. They know from the first all that is to be known, and cannot see any reason for secrecy concerning natural laws or the powers and senses that have been given them from birth." (_Zeitschrift für Ethnologie_, 1898, Heft 6, p. 479.) Of the Monbuttu of Central Africa, another observer says: "It is surprising how a Monbuttu woman of birth can, without the aid of dress, impress others with her dignity and modesty." (_British Medical Journal_. June 14, 1890.) "The women at Upoto wear no clothes whatever, and came up to us in the most unreserved manner. An interesting gradation in the arrangement of the female costume has been observed by us: as we ascended the Congo, the higher up the river we found ourselves, the higher the dress reached, till it has now, at last, culminated in absolute nudity." (T.H. Parke, _My Personal Experiences in Equatorial Africa_, 1891, p. 61.) "There exists throughout the Congo population a marked appreciation of the sentiment of decency and shame as applied to private actions," says Mr. Herbert Ward. In explanation of the nudity of the women at Upoto, a chief remarked to Ward that "concealment is food for the inquisitive." (_Journal of the Anthropological Institute_, 1895, p. 293.)
