The Love Sonnets of Proteus, Juliet, XXXIV: The same continued

Yes, Spring is come, but joy alas is gone, —
Gone ere we knew it, while our foolish eyes,
Which should have watched its motions every one
Were looking elsewhere, at the hills, the skies,
Chasing vain thoughts, as children butterflies,
Until the hour struck and the day was done,
And we looked up in passionate surprise
To find that clouds had blotted out our sun.
Our joys are gone. And what is left to us,
Who loved not even love when it was here ?
What but a voice which sobs monotonous
As these sad waves upon the rocks, the dear
Fond voice which once made music with our own,
And which our hearts now ache to think upon.
