While the book may appear to be a travel journal, broken up into chapters for each day, this is deceptive. The actual trip took two weeks and while given passages are a literal description of the journey — from Concord, Massachusetts, down the Concord River to the Middlesex Canal, to the Merrimack River, up to Concord, New Hampshire, and back — much of the text is in the form of digressions by the Harvard-educated author on diverse topics such as religion, poetry, and history. Thoreau relates these topics to his own life experiences, often in the context of the rapid changes taking place in his native New England during the Industrial Revolution, changes that Thoreau often laments.
