Reuel made no wish, but thought of the spot where the accident had occurred upon the River Charles weeks before. He was startled to observe a familiar scene where he had often rowed for pleasure on pleasant summer evenings. Every minute particular of the scenery was distinctly visible. Presently the water seemed to darken, and he saw distinctly the canoe containing Aubrey, Molly and Dianthe gliding over the water. He started back aghast, crying out, “It is magical!”

“No, no, Ergamenes, this is a secret of Nature. In this disk I can show thee what thou wilt of the past. In the water of the font we see the future. Think of a face, a scene—I will reflect it for thee on this disk. This is an old secret, known to Ethiopia, Egypt and Arabia centuries ago. I can reflect the past and the faces of those passed away, but the living and the future are cast by the water.”

Reuel was awed into silence. He could say nothing, and listened to Ai’s learned remarks with a reverence that approached almost to worship before this proof of his supernatural powers. What would the professors of Harvard have said to this, he asked himself. In the heart of Africa was a knowledge of science that all the wealth and learning of modern times could not emulate. For some time the images came and went upon the mirror, in obedience to his desires. He saw the scenes of his boyhood, the friends of his youth, and experienced anew the delights of life’s morning. Then he idly desired to see the face of his loved Dianthe, as she last appeared on earth. The surface of the disk reflected nothing!

“You have not reached perfection then, in this reflector?”

“Why think you so?” asked Ai gravely.

“I have asked to see the face of a friend who is dead. The mirror did not reflect it.”

“The disk cannot err,” said Ai. “Let us try the water in the font.”

“But that reflects the living, you say; she is dead.”

“The disk cannot err,” persisted Ai. He turned to the font, gazed in its surface, and then beckoned Reuel to approach. From the glassy surface Dianthe’s face gazed back at him, worn and lined with grief.

“’Tis she!” he cried, “her very self.”
