It is here, and to this end, that the able teacher steps in, to perfect the development of the future man and woman. He educates, by assisting the natural unfolding of the intellectual germ, he places within reach of the child-mind the food needed to its growth, and the child-mind reaches out its tentacles and absorbs the nourishment offered to it. Thus the mind grows from _within outward_, and the teacher aids its development, as the careful husbandman by tilling and enriching the soil according to the nature of the plant he cultivates, produces a healthy and fruitful plant. The true teacher does not seek to teach by simply putting books into the child's hand, and bidding it to learn; he addresses himself to those faculties and powers of the child's mind, which bring it in relation with the world in which it lives. Sight, hearing, touch, smell, taste, and thence observation, judgment, perception, reason, memory, hope, imagination, and the love of the beautiful are appealed to, developed and strengthened by natural exercise, even as the organs and limbs of the body are developed and strengthened by gymnastic and other appropriate exercises. Education, mental and physical, is but the ABSORPTION of surrounding elements into the mind and body--an arrangement an assimilation of materials so as to incorporate them into the being to whose nourishment they are applied, just as the tree or plant assimilates to its growth and subsistence the materials which it draws from the air and the soil.
