Most of those, however, who came to us at the age of six or seven had already been taught to regard anything connected with the sexual organs as improper. They were surprised to find that in the school such matters were spoken of in the same tone of voice as was employed about anything else, and for some time they enjoyed a sense of release in conversations which they felt to be indecent ; finding, however, that the grown-ups did nothing to check such conversations, they gradually wearied of them, and became nearly as clean-minded as those who had never been taught decency.
