When smoke stood up from Ludlow,
And mist blew off from Teme,
And blithe afield to ploughing
Against the morning beam
I strode beside my team,

The blackbird in the coppice
Looked out to see me stride,
And hearkened as I whistled
The trampling team beside,
And fluted and replied:

"Lie down, lie down, young yeoman;
What use to rise and rise?
Rise man a thousand mornings
Yet down at last he lies,
And then the man is wise."

I heard the tune he sang me,
And spied his yellow bill;
I picked a stone and aimed it
And threw it with a will:
Then the bird was still.

Then my soul within me
Took up the blackbird's strain,
And still beside the horses
Along the dewy lane
It sang the song again:

"Lie down, lie down, young yeoman;
The sun moves always west;
The road one treads to labour
Will lead one home to rest,
And that will be the best."

Alfred Edward Housman
