Nature and Human Existence
In 1851, Thoreau became increasingly fascinated with natural history and narratives of travel and expedition. He read avidly on botany and often wrote observations on this topic into his journal. He admired William Bartram and Charles Darwin's Voyage of the Beagle. He kept detailed observations on Concord's nature lore, recording everything from how the fruit ripened over time to the fluctuating depths of Walden Pond and the days certain birds migrated.
Thoreau's friend Ellery Channing published his first biography, Thoreau the Poet-Naturalist, in 1873. Channing and another friend, Harrison Blake, edited some poems, essays, and journal entries for posthumous publication in the 1890s. Thoreau's journals, which he often mined for his published works but which remained largely unpublished at his death, were first published in 1906 and helped to build his modern reputation. A new, expanded edition of the journals is under way, published by Princeton University Press.

Heard Thoreau's lecture before the Lyceum on the relation of the individual to the State—an admirable statement of the rights of the individual to self-government, and an attentive audience. His allusions to the Mexican War, to Mr. Hoar's expulsion from Carolina, his own imprisonment in Concord Jail for refusal to pay his tax, Mr. Hoar's payment of mine when taken to prison for a similar refusal, were all pertinent, well considered, and reasoned. I took great pleasure in this deed of Thoreau's.
