A Week on the Concord and Merrimack Rivers

A Week on the Concord and Merrimack Rivers is a book by Henry David Thoreau, first published in 1849. The book is ostensibly the narrative of a boat trip from Concord, Massachusetts to Concord, New Hampshire and back Thoreau had taken with his brother John in 1839. As John had died from tetanus in 1842, Thoreau wrote the book as a tribute to his memory.
