Paul Muldoon gives a close reading of Robert Frost's "Directive", a poem that seems capable of standing at the end of almost every trail in the rest of Frost's own work, but also of helping a reader find a way through the densities of 20th, perhaps even 21st, century poetry.

A joint initiative with the Poetry Society of America, Branching Out: Poetry for the 21st Century is funded by the National Endowment for the Humanities.
