The following text is from Paul Laurence Dunbar’s 1913 poem “The Poet and His Song.”
A song is but a little thing,
And yet what joy it is to sing!
In hours of toil it gives me zest,
And when at eve I long for rest;
When cows come home along the bars,
And in the fold I hear the bell,
As Night, the shepherd, herds his stars,
I sing my song, and all is well.
