 ferent. Deprived of air it would die; but if only a sufficient amount of the gas was introduced to stupefy an ordinary creature it would have no effect upon the rykor, who had no objective mind to overcome. So long as the excess of carbon dioxide in the blood was not sufficient to prevent heart action, the rykor would suffer only a diminution of vitality; but would still respond to the exciting agency of the kaldane's brain.

Ghek caused the rykor to assume a sitting position with its back against the wall where it might remain without direction from his brain. Then he released his contact with its spinal cord; but remained in position upon its shoulders, waiting and watching, for the kaldane's curiosity was aroused. He had not long to wait before the lights were flashed on and one of the locked doors opened to admit a half-dozen warriors. They approached him rapidly and worked quickly. First they removed all his weapons and then, snapping a fetter about one of the rykor's ankles, secured him to the end of one of the chains hanging from the walls. Next they dragged the long table to a new position and there bolted it to the floor so that an end, instead of the middle, was directly before the prisoner. On the table before him they set food and water and upon the opposite end of the table they laid the key to the fetter. Then they unlocked and opened all the doors and departed.
