"To Spring" by William Wordsworth.

O Thou, whose vigorous season is
Now on the point of issuing forth,
When Heaven and Earth, in concert meet,
And all around is fresh and bright:

The snowdrop, Winter's timid child,
Awakens not to sunshine, but to cold;
Yet is not cheered, but, in the darkness,
Finds a light that guides it:

And so, when Thou, O Spring, dost come,
However late, however long delayed,
Thou show'st that Winter's grasp is not
So stern as it seemed; and that thy breath
Can breathe life into the deadest thing.
