John Burroughs at the Site of Thoreau's Walden Pond Cabin, September 1913

In 1913, naturalist John Burroughs accompanied by a group of friends visited Concord, Massachusetts, where two of Burroughs's early literary influences -- Ralph Waldo Emerson and Henry David Thoreau -- once resided. Burroughs and his traveling companions visited Emerson's home, Walden Pond and the gravesites of the two 19th-century Transcendentalists.
