Believe unless we take them for ourselves Now: soon: by the clock: before tomorrow: Others will take them: not for now: for longer."" This is the text for this new poem by one of America's leading poets. Memorable, not as a landmark in our literary history, as was his Conquistador, but because of its awareness, its timeliness. MacLeish, through his appointment to the post of Librarian of the Library of Congress; has achieved new stature in the public eye. This poem should make an easy plus sale, to thoughtful, discriminating readers.
