How do you know that the pilgrim track
Along the belting zodiac
Swept by the sun in his seeming rounds
Is traced by now to the Fishes' bounds
And into the Ram, when weeks of cloud
Have wrapt the sky in a clammy shroud,
And never as yet a tinct of spring
Has shown in in the Earth's apparelling;
O vespering bird, how do you know,How do you know?
How do you know, deep underground,
Hid in your bed from sight and sound,
Without a turn in the temperature,
With weather life can scarce endure,
That light has won a fraction's strength,
And day put on some moments' length,
Whereof in merest rote will come,
Weeks hence, mild airs that do not numb,
O crocus root, how do you know,How do you know?
Poem found in The Four Seasons, a volume from the Everyman's Library Pocket Poets series. With familiar and less familiar poems, this is a beautiful volume that fits perfectly in the hand. Highly recommended.
