JOHN
Well, what?
ALI
He that taketh this crystal, so, in his hand, at night, and wishes, saying "At a certain hour let it be"; the hour comes and he will go back eight, ten, even twelve years if he will, into the past, and do a thing again, or act otherwise than he did. The day passes; the ten years are accomplished once again; he is here once more; but he is what he might have become had he done that one thing otherwise.
MARY
John!
JOHN
I—I don't understand.
ALI
To-night you wish. All to-morrow you live the last ten years; a new way, master, a new way, how you please. To-morrow night you are here, what those years have made you.
