The play instinct of the child is as old as the race, or older,
and is a vitally important factor, not only in physical
development, but also in mental development. In its destructive
and disorderly activities the child shows the later adult
forces in the formative stage. Old instincts and movements that
were once self-preservative and of serious meaning to a wild
ancestor reappear in the play of children, and, utilized
wisely, may under new form become a valuable possession of the
adult. There is a great big man, in fact, several possible men,
inside every boy. Through his running, jumping, fighting,
swimming, through impulse, instincts and emotions he is seeking
the man that is in him, and it is by this turbulent and
experimental course that he finally comes to the order of
maturity.
