Volume 8 (of 20)
Journal II, 1850-September 15, 1851
From 1837 to 1861, Thoreau kept a Journal that began as a conventional record of ideas, grew into a writer’s notebook, and eventually became the principal imaginative work of his career. The source of much of his published writing, the Journal is also a record of his interior life and of his monumental studies of the natural history of his native Concord, Massachusetts. Unlike earlier editions, the Princeton edition reproduces the Journal in its original and complete form, in a reading text free of editorial interpolations but keyed to a comprehensive scholarly apparatus.
