A presence that disturbs me with the joy
Of elevated thoughts; a sense sublime
Of something far more deeply interfused,
Whose dwelling is the light of setting suns,
And the round ocean, and the living air,
And the blue sky, and in the mind of man,
A motion and a spirit, that impels
All thinking things, all objects of all thought,
And rolls through all things.

Would, meeting in one clasp, be made the same;
Two souls, the shores wave-mocked of sundering seas: —

Such are we now. Ah! may our hope forecast
Indeed one hour again, when on this stream
Of darkened love once more the light shall gleam? —
An hour how slow to come, how quickly past, —
Which beams and fades, and only leaves at last,
Faint as shed flowers, the attenuated dream.

And the fields echo to the gleaner's song,
Come when the splendid fulness of the moon
Looks down upon the rows of golden sheaves,
