Classicly

One of the great thinkers of the world has said that all the sciences are embodied in natural history. Hence natural history should be taught to a child from an early age. Perhaps the best method of teaching it is to set forth the characteristics of animals in the form of a narrative. Then the child reads the narrative with pleasure and almost as a story, not as a tedious "lesson."

I have followed that method in the Wonders of the Jungle. The present work (Book One) is intended to be a supplementary reader for the earlier grades in grammar schools. If it be found useful, I shall write one or two more books in progressive order for the use of higher grades.
