The walker has no axe to grind; he sniffs the air for new adventure; he loiters in old scenes, he gleans in old fields. He only seeks intimacy with Nature to surprise her preoccupied with her own affairs. He seeks her in the woods, the swamps, on the hills, along the streams, by night and by day, in season and out of season. He skims the fields and hillsides as the swallow skims the air, and what he gets is intangible to most persons. He sees much with his eyes, but he sees more with his heart and imagination. He bathes in Nature as in a sea. He is alert for the beauty that waves in the trees, that ripples in the grass and grain, that flows in the streams, that drifts in the clouds, that sparkles in the dew and rain. The hammer of the geologist, the notebook of the naturalist, the box of the herbalist, the net of the entomologist, are not for him. He drives no sharp bargains with Nature, he reads no sermons in stones, no books in running brooks, but he does see good in everything. The book he reads he reads through all his senses--through his eyes, his ears, his nose, and also through his feet and hands--and its pages are open everywhere; the rocks speak of more than geology to him, the birds of more than ornithology, the flowers of more than botany, the stars of more than astronomy, the wild creatures of more than zooelogy. The average walker is out for exercise and the exhilarations of the road, he reaps health and strength; but Thoreau evidently impaired his health by his needless exposure and inadequate food. He was a Holy-Lander who falls and dies in the Holy Land. He ridiculed walking for exercise--taking a walk as the sick take medicine; the walk itself was to be the "enterprise and adventure of the day." And "you must walk like a camel, which is said to be the only beast which ruminates while walking." IV
