_Occupation of Mother_:--Probably of more importance than the size of the family is the economic position of the mother, particularly during the years of the daughter's adolescence. It is a vital loss if a girl's mother is away from home all day, leaving her after school hours to associates of whom the mother knows nothing and who may be most questionable in their influence on her developing character. In 145 instances, or in 22.4 percent of the total number of cases studied, the mother worked outside the home. Table VII gives a list of the occupations of working mothers, with the number in each group. It will be seen that the women who went out for day's work are much the largest group. They went out to wash, to clean, to scrub offices and for other unskilled labor. The laundresses were employed partly in steam laundries and partly in private families and came home at night. Of the 145 mothers who worked, there were 94 who were widows; one mother was divorced; the husband and father in one case was an inmate of a sanitarium for tuberculosis; in one case the father was in an insane asylum; in 8 cases the father had deserted his family; in 40 cases the husband and father was alive and working. The necessity for earning a livelihood explains simply the leaving of children alone in the group of widows. In the 40 cases where the husband was working, no special necessity for the mother's occupation is shown by our data. The 40 husbands and fathers whose wives went out to work, were engaged in thirty-one different occupations, no one group numbering more than four men. These were the day laborers. Three were colored cooks; three were teamsters; two were carpenters; others include a stationary engineer, a walking delegate, an insurance agent, a market man, an elevator man, etc. Neither did the size of the family afford a special excuse, as in these forty families there was an average of four children. One family contained ten children; two families each had seven and eight respectively, while the greatest number in any one group was ten families with three children each. It may be that the father was inefficient or irregular in his occupation or the family standards of living were higher. It would be necessary to know all of these details in each family to offer any opinion as to reasons and we have not these data.
