Here you will find the Poem A Green Cornfield of poet Christina Georgina Rossetti
The earth was green, the sky was blue: I saw and heard one sunny morn A skylark hang betweent he two, A singing speck above the corn; A stage below, in gay accord, White butterflies danced on the wing, And still the singing skylark soared, And silent sank and soared to sing. The cornfield stretched a tender green To right and left beside my walks; I knew he had a nest unseen Somewhere among the million stalks. And as I paused to hear his song While swift the sunny moments slid, Perhaps his mate sat listening long, And listened longer than I did.
