Read the passage from "A Corn-Song."
On the wide veranda white,
In the purple failing light,
Sits the master while the sun is lowly burning;
And his dreamy thoughts are drowned
In the softly flowing sound
Of the corn-songs of the field-hands slow returning.
Oh, we de co'n
Since de ehly mo'n;
Now de sinkin' sun
Says de day is done.
