After a childhood spent on a Long Island farm followed by limited schooling in Brooklyn and a modestly successful career as teacher, carpenter, and journalist, Walt Whitman published his epic poem, Leaves of Grass (1855), at the age of thirty-six. His vision of America had been enlarged and his poetic imagination enhanced by an 1848 journey he made across the Appalachians and down the Ohio and Mississippi rivers to New Orleans.

Miller concludes that Whitman discovered and expanded our understanding of
