He summoned all his strength to pull free and could not. Not only did that hold grip him, but his other hand and arm were being drawn to join the first! Inside Travis primitive fears awoke full force, and he threw back his head, voicing a cry of panic as wild as that of a hunting beast. An instant later, his left palm was as tight a prisoner as his right. And with both hands so held, his whole body was suddenly snapped forward, off the safe foundation of the floor, tight to the pillar. In this position he was sucked down into the well. And while unable to free himself from the pillar, he did slip along its length easily enough. Travis shut his eyes in an involuntary protest against this weird form of capture, and a shiver ran through his body as he continued to descend. After the first shock had subsided the Apache realized that he was not truly falling at all. Had the pillar been horizontal instead of vertical, he would have gauged its speed that of a walk. He passed through two more room enclosures; he must already be below the level of the valley floor outside. And he was still a prisoner of the pillar, now in total darkness. His feet came down against a level surface, and he guessed he must have reached the end. Again he pulled back, arching his shoulders in a final desperate attempt at escape, and stumbled away as he was released. He came up sideways against a wall and stood there panting. The light, which might have come from the pillar but which seemed more a part of the very air, was bright enough to reveal that he was in a corridor running into greater dark both right and left. Travis took two strides back to the pillar, fitted his palms once again to its surface, with no result. This time his flesh did not adhere and there was no possible way for him to climb that slick pole. He could only hope that at some point the corridor would give him access to the surface. But which way to go--? At last he chose the right-hand path and started along it, pausing every few steps to listen. But there was no sound except the soft pad of his own feet. The air was fresh enough, and he thought he could detect a faint current coming toward him from some point ahead--perhaps an exit. Instead, he came into a room and a small gasp of astonishment was wrung out of him. The walls were blank, covered with the same ripples of blue-purple-green light which colored the pillar. Just before him was a table and behind it a bench, both carved from the native yellow-red mountain rock. And there was no exit except the doorway in which he now stood. Travis walked to the bench. Immovable, it was placed so that whoever sat there must face the opposite wall of the chamber with the table before him. And on the table was an object Travis recognized immediately from his voyage in the alien star ship, one of the reader-viewers through which the involuntary explorers had learned what little they knew of the older galactic civilization.
