On one of the coldest days in winter the field worker visited the street in a city slum where three sons of Joseph (Chart IX, section D) live. She had previously tested several of the children of these families in the public school and found them, in amiability of character and general mentality, strikingly like our own Deborah, lacking, however, her vitality. There was no fire in their eyes, but a languid dreamy look, which was partly due, no doubt, to unwholesome city environment. In one house she found the family group--six human beings, two cats, and two dogs--huddled in a small back room around a cook stove, the only fire in the house. In this room were accumulated all the paraphernalia of living. A boy of eleven, who had been tested in the school previously, was standing by the fire with a swollen face. He had been kept home on this account. In a rocking-chair, a little girl of twelve was holding a pale-faced, emaciated baby. In the corner two boys were openly exposing themselves. The mother was making her toilet by the aid of a comb and basin of water, set on the hearth of the stove; a pot and kettle were on top. The entrance of the field worker caused no commotion of any kind. The boy with the swollen face looked up and smiled, the mother smiled and went on with her toilet, the girl with the baby smiled, the boys in the corner paid no attention. A chair was finally cleared off and she sat down, while everybody smiled. She learned that the husband made a dollar a day and that the girl next older than the child of twelve was married and had a baby. Another younger girl was at school, the family having been at last able to provide her with shoes. The girl of twelve should have been at school, according to the law, but when one saw her face, one realized it made no difference. She was pretty, with olive complexion and dark, languid eyes, but there was no mind there. Stagnation was the word written in large characters over everything. Benumbed by this display of human degeneracy, the field worker went out into the icy street. * * * * *
