From the cover, "Naturalist, essayist and early environmentalist, Henry David Thoreau (1817-1862) was one for whon nature was a religion. In communing with the natural world, he wished to "live, deliberatley, to front only the essential facts of life, and...learn what it had to teach." Toward that end Thoreau built a cabin on the shores of Walden Pond in the spring of 1845-on land owned by Ralph Waldo Emerson-outside Concord, Massachusetts. There he observed nature, farmed, built fences, surveyed and made entries in his journal. The product of his two-year sojourn at the pond was this book-one of the great classics of American letters."
