The way was new to all of them, for Balza had never been far south of the cave village; and this, combined with the darkness, retarded them, so that it was almost dawn when they reached the escarpment.

For much of the way Tarzan carried Rhonda who was almost exhausted by all that she had passed through, and only thus were they able to progress at all. But Balza was tireless, moving silently in the footsteps of her man, as she now considered Tarzan. She did not speak, for experience and instinct both had trained her to the necessity for stealth if one would pass through savage nights alive. Every sense must be alert, concentrated upon the business of self-preservation. But who may know what passed in that savage little brain as the beautiful creature followed her new lord and master out into a strange world?

In the early dawn the scene from the top of the escarpment looked weird and forbidding to Rhonda Terry. The base was mist hidden. Only the roar of the falls, rising sepulchral, like the voices of ghostly Titans from the tomb, belied the suggestion of bottomless depth. She seemed to be gazing down into another world, a world she would never reach alive.

Strong in her memory was that other experience when the giant gorilla had carried her up this dizzy height. She knew that she could never descend it safely alone. She knew that Stanley Obroski could not carry her down. She had learned that he could do many things with the possibility of which none might ever have credited him a few weeks before, but here was something that no man might do. She even doubted his ability to descend alone.

Even as these thoughts passed quickly through her mind the man swung her across one broad shoulder and started the descent. Rhonda gasped, but she clenched her teeth and made no outcry. Seemingly with all the strength of the bull gorilla and with far greater agility he swung down into the terrifying abyss, finding foothold and hand hold with unerring accuracy; and after him came Balza, the wild-girl, as sure of herself as any monkey.

And at last the impossible was achieved—the three stood safely at the foot of the escarpment. The sun had risen, and before it the mist was disappearing. New hope rose in the breast of the American girl, and new strength animated her body.

"Let me down, Stanley," she said. "I am sure I can walk all right now. I feel stronger."

He lowered her to the ground. "It is not a great way to the camp where I left Orman and the others," he said.

Rhonda glanced at Balza and cleared her throat. "Of course we're all from Hollywood," she said, "but don't you think we ought to rig some sort of skirt for Balza before we take her into camp?"

Tarzan laughed. "Poor Balza," he said; "she will have to eat of the apple soon enough now that she is coming into contact with civilized man. Let her keep her naturalness and her purity of mind as long as she may."
