moment he was unfortunately called out by a person on business from Porlock, and detained by him above an hour, and on his return to his room, found to his no small surprise and mortification, that though he still retained some vague and dim recollection of the general purpose of the vision, yet, with the exception of some eight or ten scattered lines and images, all the rest had passed away like the images on the surface of a stream into which a stone has been cast, but, alas! without the after restoration of the latter:
Then all the charm
Is broken—all that phantom-world so fair
Vanishes, and a thousand circlets spread,
And each mis-shape the other. Stay awhile,
Poor youth! who scarcely dar'st lift up thine eyes—
The stream will soon renew its smoothness, soon
The visions will return! And lo, he stays,
And soon the fragments dim of lovely forms
Come trembling back, unite, and now once more
The pool becomes a mirror.
