" To my way of thinking and working the greatest service a piece of fiction can do any reader is to leave him with a higher ideal of life than he had when he began. If in one small degree it shows him where he can be a gentler, saner, cleaner, kindlier man, it is a wonder-working book. If it opens his eyes to one beauty in nature he never saw for himself, and leads him one step toward the God of the Universe, it is a beneficial book, for one step into the miracles of nature leads to that long walk, the glories of which so strengthen even a boy who thinks he is dying, that he faces his struggle like a gladiator.
