What The Thrush Said. Lines From A Letter To John Hamilton Reynolds

O thou whose face hath felt the Winter's wind,
Whose eye has seen the snow-clouds hung in mist
And the black elm tops 'mong the freezing stars,
To thee the spring will be a harvest-time.
O thou, whose only book has been the light
Of supreme darkness which thou feddest on
Night after night when Phoebus was away,
To thee the Spring shall be a triple morn.
O fret not after knowledge, I have none,
And yet my song comes native with the warmth.
O fret not after knowledge, I have none,
And yet the Evening listens. He who saddens
At thought of idleness cannot be idle,
And he's awake who thinks himself asleep.
