It is not advisable that the child should be taught always in the house, nor always at school. The study should be divided, partly indoors and partly outdoors. The teaching given to a child indoors should be different from the study given out of doors. The outdoor study should concern all that the child sees; one can then include the practice or the experience of what it has learned indoors. In short, a child's health must be considered as part of its education; study and health go together.
