"He is not needed," Tork's suave voice said. From the ground beside Nixon, Frane's voice sounded. He was talking in his own language, angrily expostulating. Then he called, in English, "I tell them this is not necessary." "But your success with the drug is postponed too long," one of the Orite leaders said. "Tork says you are doing your best, but—" "I will succeed within another night," Frane desperately promised. "One more experiment—" Surely the aged scientist was doing what he could to stall this. But they had lost confidence in him. He should have used the panther, and then this giant man long ago. Frane was a brilliant chemist, but he had no qualities of dominating leadership. "Only this can help you," the leader said. His voice carried finality. He gestured, added a command in the Orite language to the surgeons. Nixon could feel the figures on his neck moving to begin their gruesome work on the prone, half-conscious giant. But Nixon was more conscious, stronger now than they realized. He strained at the cables, but found that he could move far less than when he had been bound on the Spaceship. His head could shift a little so that he could glance sidewise, but that was all.

Then his roar held his mingled horror and a queer sort of triumph. "So now you've got something else to worry about!" he shouted. "There it is—mean and hungry. Take a look at that critter, you damn butchers, and see what you're going to do about it!" The panther was loose. Nixon remembered now, how Loto had said it was in a cave with a purple barrage barring the entrance. Loto and Nixon had never thought of it—that when Loto pulled the barrage-switch, for that moment the
