back, a rope around his wrists, and while the rest walked behind, one man led Allerdyce from the cave into the open, across a level stretch of ground and into a very large cave. Here his wrists were unbound and to the jibes and laughter of the warriors who had accompanied him, Allerdyce was shoved into the cave proper itself.

The cave was immense, and seemed to be filled entirely with women and children. For a second there was silence. Then as their eyes saw this almost naked stranger, a wild shriek of laughter went up. Hands went out, pointing to his shorts which seemed to be all the clothing he had, to his face, puffed into a gargoylish mask, and to his hairy chest, which looked like the stuffing of a mattress.

Allerdyce stared in horror at the women, turned and started for the cave entrance. But the cavemen had anticipated his move. They stood guard, spears thrust point forward, and after a few hesitant seconds, Allerdyce turned back.

But now they were no longer scattered about the cave. They came over in a rush, forcing him to the wall, his hands pawing in futile attempts to prevent them from touching him. For some reason this made them angry. Their hands clenched and spiteful words came from their lips, and several turned aside and called something to the children, who after a moment returned, with stones and sticks.

"Hey!" Allerdyce called in alarm. "Take it easy...."

The alarm in his voice was the signal for them to attack. In a moment he was the center of a mob of women all bent, it seemed, on his destruction. He fought at first as gently as he could. But as some of the stones hit and some of the clubs struck vulnerable parts of his anatomy, he fought with less gentleness. Finally, he was forced to club one of the women with his fist. She went flying backward and landed flat on her back.

nstantly the attack ceased.

He watched them move away from him and wondered why. His question was answered as the woman he had struck crawled to him and embraced his legs. He tried to withdraw her hands but she held only tighter and said:

"We are mated. You made the choice. I am Sala...."

"You're nuts!" Allerdyce said sharply. He turned to call the guards to help him with the woman when he discovered that they were gone.

"Are customs different in your tribe?" Sala asked. "Do you not mate with a woman in this manner?"

The beginning of a hope came to him in a rush as he realized the consequences of what had happened. He was free now. He tried to put the proper authority in his voice, when he said:

"Go woman! Find me a corner and bring me food...."

Without the slightest hesitation Sala rose and trotted to a far corner of the cave. Allerdyce followed and squatted beside her. He had always been a shy man and had never known many women, especially women with as little clothes as Sala wore. She was beautiful by any standard he thought. But only for a moment. His thoughts for the first time centered on his predicament.

His mind allowed for but a single conclusion. That the plane had run into a time-fault and that he and Ed Finster had been drawn into it. The others must have died in the plane crash. Since the giant ship was over the Atlantic at the time of the crash it was reasonable to assume that time only was involved and not space. Therefore, by the same line of reasoning, he and Ed were to be here for the rest of their lives. That is unless somehow they found the same fault again. But that was not probable, he realized.

For a moment fear lay heavy on him. Then the scientist came uppermost. What an opportunity he had. A man of science among these children. The chance to build a civilization. It could be done with his knowledge. But first he had to get the power over these people.

Sala came back just then with what looked like the leg of a rabbit. It
