Leaves of Grass, 1856
•Whitman has Emerson’s praise printed on the spine in gold letters: “I greet you at the beginning of a great career.” •“I do not believe that all the sermons, so-called, that have been preached in this land put together are equal to it for preaching." Henry David Thoreau
Adds 20 new poems and includes several reviews of the first edition, including two written by Whitman himself.

Despite doubts about its sexual content, Thoreau praises the volume.
Emerson is said to be understandably annoyed at Whitman’s unauthorized use of the letter, which has been affixed to a volume containing poems that he has never seen.
