Walden or Life in the Woods, by Henry D. Thoreau, with an introduction and notes by Francis H. Allen. Houghton Mifflin Company, 1910. The Riverside Literature Series. Borst A2.8d. Includes four black and white photos (three of Walden Pond), an introduction, a list of Thoreau's books, and suggestive questions and comments, and an index. What a nice edition! Pages are tanning lightly, and the green hardcover has a bit of edge wear, but otherwise, this is quite the handy volume. Not a common edition to find.
