The pointer stopped at "1." He heard it click into position there.

Instantly, something slammed him sideways against the console, sent him staggering along it, and over the low railing at the end of the platform. The floor seemed to be shuddering as he struck it, and then to tilt slowly. Dowland rolled over, came up on hands and knees, facing back toward the platform. Daylight blazed again in the building behind him, and the roar of a river that rolled through another time filled his ears. He got to his feet, plunged back toward the whipping rope above the platform. The light and the roaring cut off as he grasped the rope, flashed back into the building, cut off again. Somewhere somebody had screamed....

Dowland swung about on the rope, went handing himself along it, back toward the door. His feet flopped about over the floor, unable to get a stand there for more than an instant. It was a struggle now to get enough air through the antiradiation field into his lungs. He saw dust whip past the open door, momentarily obscuring it. The building bucked with earthquake fury. And where was Trelawney?

He saw the red, wet thing then, lying by the wall just inside the door; and sickness seized him because Trelawney's body was stretched out too far to make it seem possible it had ever been that of a man. Dust blasted in through the door as he reached it, and subsided, leaving a choking residue trapped within the radiation screen. If he could only cut off the field....



His gun lay too close to the sodden mess along the wall. Dowland picked it up, was bending to snatch the climbing harness from the floor when light flared behind him again. Automatically, he looked back.

Once more the interior of the building seemed to have split apart. Wider now. He saw the rushing white current below. To the right, above the forest on the bank, the sun was a swollen red ball glaring through layers of mist. And to the left, moving slowly over the river in the blaze of long-dead daylight, was something both unmistakable and not to be believed. But, staring at it in the instant before the scene shivered and vanished again, Dowland suddenly thought he knew what had happened here.

What he had seen was a spaceship.
