Girls, at the age of twelve, thirteen, or fourteen, should have presented to them a course in physiology which includes the anatomy and hygiene of the reproductive organs. This is carefully omitted from present-day secondary-school textbooks. This course should use charts, pictures, and models. The significance of menstruation, the hygiene of the period, and the causes and prevention of pain should be explained. Under the hygiene of the period, the daily bath should be urged, with caution against chills, in which lies the only possibility of injury. The fertilization of the ovum and cell division may be described by use of the blackboard and embryological models of the later stages of development. The forces which bring about labor can be explained without unduly stressing the attending pain. The course would be incomplete without a discussion of the necessity of careful selection in marriage from the eugenic standpoint. The perils and results of the venereal diseases should be told simply and frankly. The instruction in eugenics, like that in reproduction, should be progressive and indirect, at least up to the age of seventeen or eighteen years. Again it may be correlated with plant life by pointing out the beauty of strong, hardy plants and their relation to the seeds. Children can be taught to save the seeds of the most beautiful blossoms for the following year. Instruction can be continued with the lower animals. The child will then grow up with the idea that strength and vigor and freedom from disease are desirable qualities, and must exist in the parent if they are to exist in the offspring. The idea can be readily carried over to the human family. At the age of seventeen or eighteen, the influence of heredity and the effects of the racial poisons should be fully explained, and emphasis laid upon qualities necessary for racial betterment. For our girls the first need is a sounder physical organism, which can be attained only through the systematic continuance of physical activities through childhood and girlhood; the second need is sounder mental interests, which can be attained only through the systematic guidance of the mental activities throughout childhood and girlhood; and the third need is instruction in laws of reproduction.
