I am indebted to the Editors of Scribner's Magazine, the Cosmopolitan, and Babyhood, for permission to reprint the three essays which have appeared in their pages. The others are published for the first time.  
It may be well to ward off the full seriousness of my title "Nursery Logic" by saying that a certain informality in all of these papers arises from the fact that they were originally talks given before members of societies interested in the training of children.
 
Three of them—"Children's Stories," "How Shall we Govern our Children," and "The Magic of 'Together'"—have been written for this book by my sister, Miss Nora Smith.
