First, to feed the child's faculties with suitable food; Second,--to simplify and explain everything, so as to adapt it properly to those faculties; Third, not to overdo anything, either by giving too much instruction, or instruction beyond their years, and thus over-excite the brain, and injure the faculties; and, Fourth, ever to blend both exercise and amusement with instruction at due intervals, which is readily effected by a moderate amount of singing, alternating with the usual motions and evolutions in the schoolroom, and the unfettered freedom of the play-ground.

If these rules be attended to, the following results are certain,--a higher state of physical, mental, and moral health.

Physical health is essential to mental vigour if it is to come to manhood.

If the physical, mental, moral, and spiritual constitution be properly acted upon, fed, and trained, it adds to the happiness of the child; but if this is not done, it becomes miserable, and as a consequence restless, troublesome, and mischievous.

Such facts were made very evident to me by the infants under my care in the earlier part of my career, and also have been fully confirmed throughout it, and they have forced me as it were to that more lively, interesting, and amusing mode of instruction, which I have through life endeavoured to propagate.
I found children to be highly delighted with pictures and object-lessons; hence their value and high importance is so strongly insisted on in all my books, and the best methods of using them distinctly laid down.
