" Piping down the valleys wild, Piping songs of pleasant glee,On a cloud I saw a child,And he laughing said to me:"Pipe a song about a Lamb!" So I piped with merry cheer. "Piper, pipe that song again;"So I piped: he wept to hear."Drop thy pipe, thy happy pipe; Sing thy songs of happy cheer!"So I sang 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, And I wrote my happy songs Every child may joy to hear."
