Nocturne in a Deserted Brickyard

Carl Sandburg. From wikipedia.org

STUFF of the moon
Runs on the lapping sand
Out to the longest shadows.
Under the curving willows,
And round the creep of the wave line,
Fluxions of yellow and dusk on the waters
Make a wide dreaming pansy of an old pond in the night.

Carl Sandburg (January 6, 1878 – July 22, 1967) was an American writer and editor, best known for his poetry. He won three Pulitzer Prizes, two for his poetry and another for a biography of Abraham Lincoln. H. L. Mencken called Carl Sandburg "indubitably an American in every pulse-beat."
