Essayist, poet, and philosopher Henry David Thoreau (1817-62) ranks among America's foremost nature writers. The Concord, Massachusetts, native spent most of his life observing the natural world of New England. His thoughts on leading a simple, independent life remain a foundation of modern environmentalism, as captured in Walden, his best-known work.Canoeing in the Wilderness, the 1857 diary of a two-week sojourn in Maine, chronicles the author's travels with a friend and a Native American guide. In the mid-nineteenth century, the Maine woodlands were still in pristine condition, inhabited by a handful of Native Americans, pioneer farmers, the occasional lumberjack, and a rich and diverse wildlife population. Thoreau's poetic yet realistic observations of the landscape are accompanied by his accounts of day-to-day events. From camping by the waterside and waking to birdsong to enduring mosquitoes and cloudbursts, he writes with grace and clarity that bring the American wilderness to vivid life.
