We should not forget that a large proportion of our children never apply for work certificates; some because they never intend to work; some because they expect to remain in school until sixteen or later; some because they live on farms, in small towns, or in cities and states where prohibition of child labor is not enforced. Because there is no reason for this large proportion of children to visit a board of health, some substitute must be found. This substitute has been already suggested by principals and district superintendents in New York City, who claim that the natural place for the examination of children is the school and not health headquarters. Developing the idea that the school should pronounce the child's fitness to leave school and to engage in work, we are led to the suggestion that the state, which compels evidence that every child, rich or poor, is being taught during the compulsory school age, shall also at the age of fourteen or sixteen require evidence that the child is physically fit to use his education, and that it shall not, because of preventable ill health, prove a losing investment. Parochial and private schools, the ultra-religious and ultra-rich, may resent for a time public supervision of the physical condition of children who do not ask for work certificates. This position will be short-lived, because however much we may disagree about society's right to control a child's act after his physical defects are discovered, few of us will question the state's duty to tell that child and his parents the truth about his physical needs before it accepts his labor or permits him to go to college, to "come out," to "enter society," or to live on an income provided by others. Thus an invaluable commencement present can be given by the state to children in country schools and to those compelled to drop out of fourth or fifth grades of city schools.
