As a fresh, original and well-balanced study of the boy, inspired by unusual insight and large experience, Kirtley’s That Boy of Yours is valuable for teachers, social workers, and above all for parents, to whom by its title it is addressed. * * * * * Thwing’s The Family has been for a generation so exclusively the one book combining for the general reader historical and social data, scholarly and practical purpose, that this revised and enlarged edition renders a public service. Unlike the more technical manuals on the family it takes for granted no special acquaintanceship with the history and literature of the subject, though it is introductory to and interpretative of both. The additional material includes the statistical and bibliographical data appearing since the first edition was published, and a new concluding chapter, significantly bearing the title, The Family Under a Socialized Society. GRAHAM TAYLOR. THE TEACHER’S HEALTH By LEWIS M. TERMAN. Houghton, Mifflin Co. 136 pp. Price $.60; by mail of THE SURVEY $.66. “Teaching as a Dangerous Trade” might have been the title of this book. Eighty-four per cent of 159 teachers in Springfield, Mass., testified that in their opinion the teacher of average physical constitution suffers distinct impairment of health within five to ten years after beginning service. Between 1906 and 1909 over a quarter of the elementary teachers of Sweden were absent one year or more on account of illness. But it is not as a matter of mere personal concern to the profession that the teacher’s health is here considered; rather as a factor in school efficiency. Medical inspection of schools is partial so long as it takes no notice of teachers, for “the health of the child is intricately related to that of its teacher.” There is a subtler way in which weak lungs and neurasthenia among the half million teachers who are molding the intellect and character of twenty million children in this country may affect the development of those children. As the editor’s introduction puts it: “If the teacher’s conscious pedagogical method transmits truth, it is the unconscious influence of his personality that gives it that bias of meaning which the fact will forever after have for the pupil.” And nowadays we are coming to know how much personality is shaped by physical and mental health.
