The Late Swallow

Leave, leave your well-loved nest,
Late swallow, and fly away.
Here is no rest
For hollowing heart and wearying wing.
Your comrades all have flown
To seek their southern paradise
Across the great earth’s downward sloping side,
And you are alone.
Why should you cling
Still to the swiftly ageing narrowing day?
Prepare;
Shake your pinions long untried
That now must bear you there where you would be
Through all the heavens of ice;
Till falling down the homing air
You light and perch upon the radiant tree.
