Analysis of Possession

THERE is a cloud above the sunset hill,
That wends and makes no stay,
For its goal lies beyond the fiery west;
A lingering breath no calm can chase away,
The onward labour of the wind's last will;
A flying foam that overleaps the crest
Of the top wave: and in possession still
A further reach of longing; though at rest
From all the yearning years,
10 Together in the bosom of that day
Ye cling, and with your kisses drink your tears.
