Read this excerpt from the poem "Lincoln Looked.” Lincoln looked forward and saw
a divided house cannot stand.
He looked ahead, beyond the brim
of his stovepipe hat, and where
there were many people, he saw one.

Lincoln looked up at the clouds
turning in the sky and knew that
the nation was doing the same thing
in time.

It was time for a change. Lincoln
looked deep within himself and searched
for the recipe for a new country made
from so many wild and unique ingredients.
