To a Linnet

My cheerful mate, you fret not for the wires,
The changeless limits of your small desires;
You heed not winter rime or summer dew,
You feel no difference 'twixt old and new;
You kindly take the lettuce or the cress
Without the cognizance of more and less,
Content with light and movement in a cage.
Not reckoning hours, nor mortified by age,
You bear no penance, you resent no wrong,
Your timeless soul exists in each unconscious song.
