In 1839, Thoreau and his brother took a small boat upriver and back. Some years later, while in his cabin at Walden Pond, he gathered his notes from that journey and other writings from his journals, and composed this, his first book. Like the rivers it describes, the book meanders through varying territories and climates. He writes of the natural surroundings they encounter and of the history of the region, but also takes long and remarkable detours through topics like friendship, history, a comparison of Christianity and Hinduism, Vedic literature, government and conscience, Thoreau's philosophy of literature, monuments and graveyards, poetry (in particular Ossian, Chaucer, and certain minor Greek poets), and the satires of Aulus Persius Flaccus. Thoreau also includes several poems of his own. Thoreau had the first edition of this book published at his own expense, and at first it struggled to find an audience. "I have now a library of nearly 900 volumes," he remarked at one point, "over 700 of which I wrote myself." Henry David Thoreau (died 1862) was one of the most distinguished authors of the Victorian age. Their work has endured across generations and continues to be read and studied worldwide. The nonfiction literature of previous centuries offers invaluable windows into the minds and preoccupations of earlier ages. A Week On The Concord And Merrimack Rivers combines the personal and the universal in ways that continue to resonate with contemporary readers seeking to understand both history and human nature.
