"Summer" by Dallas Lore Sharp is the fourth last volume of the natural history - outdoor book series by the author.

Excerpt:

"I believe that a child's interest in outdoor life is a kind of hunger, as natural as his interest in bread and butter. He cannot live on bread and butter alone, but he ought not to try to live without them. He cannot be educated on nature-study alone, but he ought not to be educated without it. To learn to obey and reason and feel—these are the triple ends of education, and the greatest of these is to learn to feel. The teacher's word for obedience; the arithmetic for reasoning; and for feeling, for the cultivation of the imagination, for the power to respond quickly and deeply, give the child the out-of-doors."
