Walt Whitman: Long, Too Long America

Long, too long America,
Traveling roads all even and peaceful you learn'd from joys and
prosperity only,
But now, ah now, to learn from crises of anguish, advancing,
grappling with direst fate and recoiling not,
And now to conceive and show to the world what your children
en-masse really are,
(For who except myself has yet conceiv'd what your children en-masse
really are?)
