If everybody wrote books like this it would be a jolly world for children and an easier world for parents. Written and illustrated by the author, the book shows children what would happen if their little misdemeanors--squeezing the cat, leaving toys on the stairs, jumping in the mud, forgetting caps, dropping tacks, eating too much fudge-- were carried to the tenth power. If instead of somebody being naughty, everybody were naughty it would be agreeable to nobody. Humorous illustrations show the child exactly what would happen. About as pleasant a way of learning how to cooperate as has ever been presented. A lark for the child and a boon to the parent.
