their supply might run short?" Kirth-Labbery fiddled with the dials under the screen. It was still possible to pick up occasional glimpses from remote sectors, though by now the heart sickened in advance at the knowledge of the inevitable end of the cast. "It is possible, Vyrko. It is the only hope. The three of us here, where the agnoton and the yellow bands are alike helpless to enter, may continue our self-sufficient existence long enough to outlast the invaders. Perhaps somewhere on Earth there are other such nuclei, but I doubt it. We are the whole of the future ... and I am old." Vyrko frowned. He resented the terrible weight of a burden that he did not want but could not reject. He felt himself at once, oppressed and ennobled. Lavra went on eating her peach. The video screen sprang into light. A young man with the tense, lined face of premature age spoke hastily, urgently. "To all of you, if there are any of you.... I have heard no answer for two days now.... It is chance that I am here. But watch, all of you! I have found how the yellow bands came here. I am going to turn the camera on it now ... watch!" The field of vision panned to something that was for a moment totally incomprehensible. "This is their ship," the old young man gasped. It was a set of bars of a metal almost exactly the color of the bands themselves, and it appeared in the first instant like a three-dimensional projection of a tesseract. Then as they looked at it, their eyes seemed to follow strange new angles. Possibilities of vision opened up beyond their capacities. For a moment they seemed to see what the human eye was not framed to grasp. "They come," the voice panted on, "from...." The voice and the screen went dead. Vyrko covered his eyes with his hands. Darkness was infinite relief. A minute passed before he felt that he could endure once more even the normal exercise of the optic nerve. He opened his eyes sharply at a little scream from Lavra. He opened them to see how still Kirth-Labbery sat. The human heart, too, is framed to endure only so much; and, as the scientist had said, he was old. It was three days after Kirth-Labbery's death before Vyrko had brought his prose-and-verse record up to date. Nothing more had appeared on the video, even after the most patient hours of knob-twirling. Now Vyrko leaned back from the keyboard and contemplated his completed record—and then
