Yet American scholars, having little or no root in the soil, commonly strive with all their might to confine themselves to the imported symbols alone. All the true growth and experience, the living speech, they would fain reject as 'Americanisms.' It is the old error which the church, the state, the school, ever commit, choosing darkness rather than light, holding fast to the old and to tradition. When I really know that our river pursues a serpentine course to the Merrimac, shall I continue to describe it by referring to some other river, no older than itself, which is like it, and call it a meander? It is no more meandering than the Meander is musketaquiding." This for Thoreau was going back to nature. Our historians of literature who cite him as an example of how to be American without being strenuous, as an instance of leisure nobly earned, are quite wrong. If any man has striven to make us at home in America, it is Thoreau. He gave his life to it; and in some measure it is thanks to him that with most Americans you reach intimacy most quickly by talking about "the woods." Thoreau gave to this American tendency the touch of genius and the depth of real thought. After his day the "back-to-nature" idea became more popular and perhaps more picturesque. Our literature becomes more and more aware of an American background. Bobolinks and thrushes take the place of skylarks; sumach and cedar begin to be as familiar as heather and gorse; forests, prairies, a clear, high sky, a snowy winter, a summer of thunderstorms, drive out the misty England which, since the days of Cynewulf, our ancestors had seen in the mind's eye while they were writing. Nature literature becomes a category. Men make their reputations by means of it. No one has yet catalogued--so far as I am aware--the vast collection of back-to-nature books that followed Thoreau. No one has ever seriously criticized it, except Mr. Roosevelt, who with characteristic vigor of phrase, stamped "nature-faking" on its worser half. But every one reads in it. Indeed, the popularity of such writing has been so great as to make us distrust its serious literary value. And yet, viewed internationally, there are few achievements in American literature so original. I will not say that John Muir and John Burroughs, upon whom Thoreau's mantle fell, have written great books. Probably not. Certainly it is too soon to say. But when you have gathered the names of Gilbert White, Jeffries, Fabre, Maeterlinck, and in slightly different _genres_, Izaak Walton, Hudson, and Kipling from various literatures you will find few others abroad to list with ours. Nor do our men owe one jot or title of their inspiration to individuals on the other side of the water.
