Then Foskatt's hand shot out, his fingers tightened about Furtig's arm. “Think,” was his order. “Think of some particular place—or person—and look at this while you do so!” Just what he meant Furtig could not understand. But when he heard the urgent tone in the other's voice he did not mistake its importance. Obediently he looked at the box—though what he should “think” about momentarily baffled him. The scene of the tiny world was again obscured with the fog, the caves hidden. Then—just why he did not know—a mind picture of Eu-La as she had watched him leave on this venture came to him from memory. Mist cleared, revealing a small rise north of the caves. But that was not quite the scene he remembered. Somehow small differences were vivid: more leaves had drifted from the trees, a patch of silver frost was on the grasses. Then a figure climbed to stand, facing him. Eu-La, but not as he had seen her last. Again certain subtle differences marked the passage of time.
