Then, if ever, come perfect days;
Then Heaven tries the earth if it be in tune, 35
And over it softly her warm ear lays:
Whether we look, or whether we listen,
We hear life murmur, or see it glisten;
Every clod feels a stir of might,
An instinct within it that reaches and towers, 40
And, grasping blindly above it for light,
Climbs to a soul for grass and flowers;
The flush of life may well be seen
Thrilling back over hills and valleys;
The cowslip startles in meadows green, 45
The buttercup catches the sun in its chalice,
And there's never a leaf or a blade too mean
To be some happy creature's palace,
The little bird sits at his door in the sun,
Atilt like a blossom among the leaves, 50
And lets his           being o'errun
With the deluge of summer it receives;
His mate feels the eggs beneath her wings,
And the heart in her dumb breast flutters and sings;
He sings to the wide world, and she to her nest,-- 55
In the nice[8] ear of nature which song is the best?
