ong after the tired girl had drifted into slumber Carruthers sat with his back against the wall, mentally trying to figure the whole thing out. The dinosaur was real enough. Yet the apemen had frightened it away, in fact had compelled it to go without actually engaging in combat. No question about it. The anthropoids were in control. But who controlled them?

Quite suddenly his eyes snapped open. Daylight had come again. He must have fallen asleep. The shrill chatter of the apeman came to his ears. The red ape leader shuffled to his feet and looked from the earth people to the spot in the jungle whence came the chatter. Abruptly he opened his mouth and emitted a flood of gibberish sounds.

The gorillas and apes at his side flattened their bodies against the rocky walls in attitudes of expectant waiting.

"What's happening?" gasped the girl.

"There's no telling," whispered Aaron. "It must be someone or something of importance. Note the expressions of awe and reverence on the faces of the apemen. My God, Nanette, look!"

Out of the depths of the jungle emerged seven white beings—human or animal it was impossible to tell. They were huge creatures with the bodies of men. Erect of carriage, almost human in looks, they contrasted strangely with the red apes and the black gorillas. Six of them appeared to act as bodyguard for the seventh.

As they reached the space in front of the two earth people, the bodyguard stepped aside. The seventh white one came to a dead stop. Long and intently he stared at the man and girl crouched against the wall. And the scrutiny seemed to please him, for he smiled.

Carruthers eyed the figure uneasily. He saw what seemed to be a man dressed in a long, fibrous garment. With white hair and beard, it was a strange figure indeed for an apeman. He saw also that the eyes were well spaced, a mark of intelligence. The forehead was high and broad. And as Carruthers mentally studied the creature, strange and bizarre thoughts crossed his mind.
