It is very desirable that no child escape inspection, because of the importance of discovering every individual of exceptional ability or inability. Since the public educational system has not yet risen to the need of this systematic mental diagnosis, private philanthropy should for the present be alert to get appropriate treatment for the unusually promising individual. In Pittsburgh, a committee of the Civic Club is seeking youths of this type, who might be obliged to leave school prematurely for economic reasons, and is aiding them to appropriate opportunities. Such discriminating selection will probably become much more widespread and we may hope a recognized function of the schools, owing to the great public demonstration of psychometry now being conducted at the cantonments for the mental classification of recruits. Compulsory education is necessary for this selection. We conclude that compulsory education, as such, is not only of service to eugenics through the selection it makes possible, but may serve in a more unsuspected way by cutting down the birth-rate of inferior families. VOCATIONAL GUIDANCE AND TRAINING In arguments for vocational guidance and education of youth, one does not often hear eugenics mentioned; yet these measures, if effectively carried out, seem likely to be of real eugenic value. The need for as perfect a correlation as possible between income and eugenic worth, has been already emphasized. It is evident that if a man gets into the wrong job, a job for which he is not well fitted, he may make a very poor showing in life, while if properly trained in something suited to him, his income would have been considerably greater. It will be a distinct advantage to have superior young people get established earlier, and this can be done if they are directly taught efficiency in what they can do best, the boys being fitted for gainful occupations, and the girls for wifehood and motherhood in addition.
