"The parents of a feeble-minded girl, twenty years of age, who was committed to the Kansas State Industrial Farm on a vagrancy charge, lived in a thickly populated Negro district which was reported by the police to be the headquarters for the criminal element of the surrounding State.... The mother married at fourteen, and her first child was born at fifteen. In rapid succession she gave birth to sixteen live-born children and had one miscarriage. The first child, a girl, married but separated from her husband.... The fourth, fifth and sixth, all girls, died in infancy or early childhood. The seventh, a girl, remarried after the death of her husband, from whom she had been separated. The eighth, a boy who early in life began to exhibit criminal tendencies, was in prison for highway robbery and burglary. The ninth, a girl, normal mentally, was in quarantine at the Kansas State Industrial Farm at the time this study was made; she had lived with a man as his common-law wife, and had also been arrested several times for soliciting. The tenth, a boy, was involved in several delinquencies when young and was sent to the detention-house but did not remain there long. The eleventh, a boy... at the age of seventeen was sentenced to the penitentiary for twenty years on a charge of first-degree robbery; after serving a portion of his time, he was paroled, and later was shot and killed in a fight. The twelfth, a boy, was at fifteen years of age implicated in a murder and sent to the industrial school, but escaped from there on a bicycle which he had stolen; at eighteen, he was shot and killed by a woman. The thirteenth child, feeble-minded, is the girl of the study. The fourteenth, a boy was considered by police to be the best member of the family; his mother reported him to be much slower mentally than his sister just mentioned; he had been arrested several times. Once, he was held in the detention-home and once sent to the State Industrial school; at other times, he was placed on probation. The fifteenth, a girl sixteen years old, has for a long time had a bad reputation. Subsequent to the commitment of her sister to the Kansas State Industrial Farm, she was arrested on a charge of vagrancy, found to be syphilitic, and quarantined in a state other than Kansas. At the time of her arrest, she stated that prostitution was her occupation. The last child was a boy of thirteen years whose history was not secured...."(1)
