The school teacher, again, on whom so many rely for the initial stage in sexual hygiene, is at present often in almost exactly the same stage of ignorance or prejudice in these matters as his or her pupils. The teacher has seldom been trained to impart even the most elementary scientific knowledge of the facts of sex, of reproduction, and of sexual hygiene, and is more often than not without that personal experience of life in its various aspects which is required in order to teach wisely in such a difficult field as that of sex, even if the principle is admitted that the teacher in class, equally whether addressing one sex or both sexes, is not called upon to go beyond the scientific, abstract, and objective aspects of sex. This difficulty of the lack of suitable teachers is not, indeed, insuperable. It would be largely settled, no doubt, if a wise and thorough course of sexual hygiene and puericulture formed part of the training of all school teachers, as, in France, Pinard has proposed for the Normal schools for young women. Dr. W.O. Henry, in a paper read before the Nebraska State Medical Association in May, 1911, put forward the proposal: "Let each State have one or more competent physicians whose duty it shall be to teach these things to the children in all the public schools of the State from the time they are eight years of age. The boys and girls should be given the instruction separately by means of charts, pictures, and stereopticon views, beginning with the lower forms of life, flowers, plants, and then closing with the organs in man. These lectures and illustrations should be given every year to all the boys and girls separately, having those from eight to ten together at one time, and those from ten to twelve, and those from over twelve to sixteen." Dr. Henry was evidently not aware that the principle of a special teacher appointed by Government to give special instruction in matters of sex in all State schools had already been adopted in Canada, in the province of Ontario; the teacher thus appointed goes from school to school and teaches the elements of sexual physiology and anatomy, and the duty of treating sexual matters with reverence, to classes of boys and of girls from the age of ten. The course is not compulsory, but any School Board may call upon the special teacher to deliver the lectures. This appointment has met with so much approval that it is proposed to appoint further teachers on the same lines, women as well as men.
