This does not mean that all information should be presented through the medium of the story. The story should be used only to give such information as is natural to the story form. But nature study can be wonderfully illuminated by the story, because many of the truths of science do lend themselves to plot, and where they have been put in parallel literary form, they are as replete with beauty and imagery as the fairy tale, and afford the fancy as free play as do the adventures of sprites and goblins. The marvel of the brown bulb or seed metamorphosing into the brilliant-hued blossom, of the homely caterpillar evolving into a bit of flying color, of the majestic movements of stars and planets through worlds remote but as exquisitely constructed as our own, fascinates the child and furnishes wide, untrammeled avenues along which his imagination may roam. There is almost no branch of science that is not rich in material for the story-teller. Dr. Carrel, the great French specialist, once said that some day an artist will arise who will weave the facts concerning the circulation of the blood into a tale as fascinating as any _conte_ from the _Arabian Nights_.
It is not likely that physiology will ever be the nucleus of stories to give to children in the early years of school life, but Dr. Carrel’s words hold a valuable hint for the narrator, who should not fail to draw from truth as freely as he draws from myth and fable. An overdose of one kind of food, no matter how wholesome, disarranges the digestive apparatus, and an overdose of one kind of literature makes a one-sided man. There are some facts to show that a too free feeding on fairy tales has led to crooked thinking and susceptibility to superstition, and the story-teller should balance his work in improbable tales with those of fact that fire the imagination because of the marvels related in them.
This is not so difficult as it may seem, for many of the truths of science have been put into simple language by men who were poet enough to bring to children something of their mystery and beauty, and there is no dearth of books that can be used with gratifying results by workers among children as young as those of six to nine years. Part of the story of evolution is enjoyed in this period. The boy in the age of fancy is fascinated by listening to an account of early man’s struggle with nature, and tales of the tree dwellers, of cave and cliff dwellers, of the discovery of fire and the adventures of the first wanderers, mean as much to him as any fairy tale, because they have the very characteristic that makes the fairy tale delightful—an element of mystery that permits the fancy to roam unchecked.
