Locally, too, these books are more noteworthy than may at first appear. They are curiously passionate, and passion in American literature since the Civil War is rare. I do not mean sentiment, or romance, or eroticism. I mean such passion as Wordsworth felt for his lakes, Byron (even when most Byronic) for the ocean, the author of "The Song of Roland" for his Franks. Muir loved the Yosemite as a man might love a woman. Every word he wrote of the Sierras is touched with intensity. Hear him after a day on Alaskan peaks: "Dancing down the mountain to camp, my mind glowing like the sunbeaten glaciers, I found the Indians seated around a good fire, entirely happy now that the farthest point of the journey was safely reached and the long, dark storm was cleared away. How hopefully, peacefully bright that night were the stars in the frosty sky, and how impressive was the thunder of icebergs, rolling, swelling, reverberating through the solemn stillness! I was too happy to sleep." Such passion, and often such style, is to be found in all these books when they are good books. Compare a paragraph or two of the early Burroughs on his birch-clad lake country, or Thoreau upon Concord pines, with the "natural history paragraph" that English magazines used to publish, and you will feel it. Compare any of the lesser nature books of the mid-nineteenth century--Clarence King's "Mountaineering in the Sierras," for example--with the current novel writing of the period and you will feel the greater sincerity. A passion for nature! Except the New England passion for ideals, Whitman's passion for democracy, and Poe's lonely devotion to beauty, I sometimes think that this is the only great passion that has found its way into American literature. Hence the "nature fakers." The passion of one generation becomes the sentiment of the next. And sentiment is easily capitalized. The individual can be stirred by nature as she is. A hermit thrush singing in moonlight above a Catskill clove will move him. But the populace will require something more sensational. To the sparkling water of truth must be added the syrup of sentiment and the cream of romance. Mr. Kipling, following ancient traditions of the Orient, gave personalities to his animals so that stories might be made from them. Mr. Long, Mr. Roberts, Mr. London, Mr. Thompson- Seton, and the rest, have told stories about animals so that the American interest in nature might be exploited. The difference is essential. If the "Jungle Books" teach anything it is the moral ideals of the British Empire. But our nature romancers--a fairer term than "fakers," since they do not willingly "fake"--teach the background and tradition of our soil. In the process they inject sentiment, giving us the noble desperation of the stag, the startling wolf-longings of the dog, and the picturesque outlawry of the ground hog,--and get a hundred readers where Thoreau got one.
