No one tendency in life as we live it in America to-day is more characteristic than the impulse, as recurrent as summer, to take to the woods. Sometimes it disguises itself under the name of science; sometimes it is mingled with hunting and the desire to kill; often it is sentimentalized and leads strings of gaping "students" bird-hunting through the wood lot; and again it perilously resembles a desire to get back from civilization and go "on the loose." Say your worst of it, still the fact remains that more Americans go back to nature for one reason or another annually than any civilized men before them. And more Americans, I fancy, are studying nature in clubs or public schools--or, in summer camps and the Boy Scouts, imitating nature's creatures, the Indian and the pioneer--than even statistics could make believable. What is the cause? In life, it is perhaps some survival of the pioneering instinct, spending itself upon fishing, or bird- hunting, or trail hiking, much as the fight instinct leads us to football, or the hunt instinct sends every dog sniffing at dawn through the streets of his town. Not every one is thus atavistic, if this be atavism; not every American is sensitive to spruce spires, or the hermit thrush's chant, or white water in a forest gorge, or the meadow lark across the frosted fields. Naturally. The surprising fact is that in a bourgeois civilization like ours, so many are affected. And yet what a criterion nature love or nature indifference is. It seems that if I can try a man by a silent minute in the pines, the view of a jay pirating through the bushes, spring odors, or December flush on evening snow, I can classify him by his reactions. Just where I do not know; for certainly I do not put him beyond the pale if his response is not as mine. And yet he will differ, I feel sure, in more significant matters. He is not altogether of my world. Nor does he enter into this essay. There are enough without him, and of every class. In the West, the very day laborer pitches his camp in the mountains for his two weeks' holiday. In the East and Middle West, every pond with a fringe of hemlocks, or hill view by a trolley line, or strip of ocean beach, has its cluster of bungalows where the proletariat perform their _villeggiatura_ as the Italian aristocracy did in the days of the Renaissance. Patently the impulse exists, and counts for something here in America. It counts for something, too, in American literature. Since our writing ceased being colonial English and began to reflect a race in the making, the note of woods-longing has been so insistent that one wonders whether here is not to be found at last the characteristic "trait" that we have all been patriotically seeking.
