On a cloud I saw a child.
And he laughing said to me.
Pipe a song about a Lamb;
So I piped with merry chear,
Piper pipe that song again—
So I piped, he wept to hear.
Drop thy pipe thy happy pipe
Sing thy songs of happy chear,
So I sung the same again
While he wept with joy to hear
Piper sit thee down and write
In a book that all may read—
So he vanish'd from my sight.
And I pluck'd a hollow reed.
And I made a rural pen,
And I stain'd the water clear,
After another  caesura  the fantasy child disappears and the poet is left in another consciousness to write his songs. What he produces in the  Songs of Innocence  are still not part of the real world, but idealised scenarios that contrast with the grim reality of the  Songs of Experience  — Blake’s social protest.
