Analysis of A Green Cornfield

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.
