college class is conscious of a vast interval of development which separates it from the class below; but it is also a period subject to Wertherian crises, such as Hume, Richter, J.S. Mill, and others passed through, and all depends on the direction given to these new forces. The dangers of this period are great and manifest. The chief of these, far greater even than the dangers of intemperance, is that the sexual elements of soul and body will be developed prematurely and disproportionately. Indeed, early maturity in this respect is itself bad. If it occurs before other compensating and controlling powers are unfolded, this element is hypertrophied and absorbs and dwarfs their energy and it is then more likely to be uninstructed and to suck up all that is vile in the environment. Far more than we realize, the thoughts and feelings of youth center about this factor of his nature. Quite apart, therefore, from its intrinsic value, education should serve the purpose of preoccupation, and should divert attention from an element of our nature the premature or excessive development of which dwarfs every part of soul and body. Intellectual interests, athleticism, social and esthetic tastes, should be cultivated. There should be some change in external life. Previous routine and drill-work must be broken through and new occupations resorted to, that the mind may not be left idle while the hands are mechanically employed. Attractive home-life, friendships well chosen and on a high plane, and regular habits, should of course be cultivated. Now, too, though the intellect is not frequently judged insane, so that pubescent insanity is comparatively rare, the feelings, which are yet more fundamental to mental sanity, are most often perverted, and lack of emotional steadiness, violent and dangerous impulses, unreasonable conduct, lack of enthusiasm and sympathy, are very commonly caused by abnormalities here. Neurotic disturbances, such as hysteria, chorea, and, in the opinion of some physicians, sick-headache and early dementia are peculiarly liable to appear and become seated during this period. In short, the previous selfhood is broken up like the regulation copy handwriting of early school years, and a new individual is in process of crystallization. All is solvent, plastic, peculiarly susceptible to external influences.
