The following case history was obtained: Because of the mother’s promiscuity, Mary’s paternity was uncertain. As a child in her mother’s home she had known only loose living, good-natured, easy-going neglect and poverty. Illegitimate births were common in the family. There seems to have been complete lack of ordinary sex morality and social standards. The family lived a roving, hand-to-mouth existence. When Mary was ten, the Court removed her and gave her to a child-placing agency. She was tried out unsuccessfully in several homes and finally made a good adjustment in a country home where she had excellent school opportunities, finishing grammar school at the head of her class.

She wandered from one position to another and came in contact with a social agency just as she was about to give up and go home again because she saw no work ahead and was unable to support herself on what she was earning. The social worker took the matter up as a vocational guidance problem and ... with the psychologist worked out the following picture of Mary:
