Book excerpt: In 1865 Walt Whitman was dismissed from his clerkship in the Department of the Interior because Secretary James Harlan judged Leaves of Grass indecent, unfit to be read aloud "by the evening lamp." Most eloquent among Whitman's defenders was William Douglas O'Connor, whose pamphlet The Good Gray Poet, a panegyric to Whitman and an attack on literary censorship in general and Harlan in particular, was the first of his many heroic if sometimes excessive efforts on Whitman's behalf.
