Of the teaching of Natural Philosophy, I will only remind the reader of what was said in an earlier chapter- that there is no part of a child's education more important than that he should lay, by his own observation, a wide basis of facts towards scientific knowledge in the future. He must live hours daily in the open air, and, as far as possible, in the country; must look and touch and listen; must be quick to note, consciously, every peculiarity of habit or structure, in beast, bird, or insect; the manner of growth and fructification of every plant. He must be accustomed to ask why- Why does the wind blow? Why does the river flow? Why is a leaf-bud sticky? And do not hurry to answer his questions for him; let him think his difficulties out so far as his small experience will carry him. Above all, when you come to the rescue, let it not be in the 'cut and dried' formula of some miserable little text book;... To get this sort of instruction for himself is simply the nature of a child: the business of the parent is to afford him abundant and varied opportunities, and to direct his observations, so that knowing little of the principles of scientific classification, he is, unconsciously, furnishing himself with the materials for such classification.
