half-animal stage, although to a large-brained, large-hearted and truly parental soul that does not call what causes it inconvenience by opprobrious names, an altogether lovable and even fascinating stage. The more we know of boyhood the more narrow and often selfish do adult ideals of it appear. Something is amiss with the lad of ten who is very good, studious, industrious, thoughtful, altruistic, quiet, polite, respectful, obedient, gentlemanly, orderly, always in good toilet, docile to reason, who turns away from stories that reek with gore, prefers adult companionship to that of his mates, refuses all low associates, speaks standard English, or is as pious and deeply in love with religious services as the typical maiden teacher or the _à la mode_ parent wishes. Such a boy is either under-vitalized and anemic and precocious by nature, a repressed, overtrained, conventionalized manikin, a hypocrite, as some can become under pressure thus early in life, or else a genius of some kind with a little of all these. But with the teens all this begins to be changed and many of these precepts must be gradually reversed. There is an outburst of growth that needs a large part of the total kinetic energy of the body. There is a new interest in adults, a passion to be treated like one's elders, to make plans for the future, a new sensitiveness to adult praise or blame. The large muscles have their innings and there is a new clumsiness of body and mind. The blood-vessels expand and blushing is increased, new sensations and feelings arise, the imagination blossoms, love of nature is born, music is felt in a new, more inward way, fatigue comes easier and sooner; and if heredity and environment enable the individual to cross this bridge successfully there is sometimes almost a break of continuity, and a new being emerges. The drill methods of the preceding period must be slowly relaxed and new appeals made to freedom and interest. We can no longer coerce a break, but must lead and inspire if we would avoid arrest. Individuality must have a longer tether. Never is the power to appreciate so far ahead of the power to express, and never does understanding so outstrip ability to explain. Overaccuracy is atrophy. Both mental and moral acquisition sink at once too deep to be reproduced by examination without injury both to intellect and will. There is nothing in the environment to which the adolescent nature does not keenly respond. With pedagogic tact we can teach about everything we know that is really worth knowing; but if we amplify and morselize instead of giving great wholes, if we let the hammer that strikes the bell rest too long against it and deaden the sound, and if we wait before each methodic step till the pupil has reproduced all the last, we starve and retard the soul, which is now all insight and receptivity. Plasticity is at its maximum, utterance at its minimum. The inward traffic obstructs the outer currents. Boys especially are often dumb-bound,
