Classic Poem

Driven in by autumn's sharpening air
From half-stripped woods and pastures bare,
Brisk Robin seeks a kindlier home:
Not like a beggar is he come,
But enters as a looked-for guest,
Confiding in his ruddy breast,
As if it were a natural shield
Charged with a blazon on the field,
Due to that good and pious deed
Of which we in the Ballad read.
But pensive fancies putting by,
And wild-wood sorrows, speedily
He plays the expert ventriloquist;
And, caught by glimpses now--now missed,
Puzzles the listener with a doubt
If the soft voice he throws about
Comes from within doors or without!
Was ever such a sweet confusion,
Sustained by delicate illusion?
He's at your elbow--to your feeling
The notes are from the floor or ceiling;
And there's a riddle to be guessed,
Till you have marked his heaving chest,
And busy throat whose sink and swell
Betray the elf that loves to dwell
In Robin's bosom, as a chosen cell.
