The former struck upon the back of his head, as Tarzan had intended that he should; and one of the ape-man's knees was at his stomach; so not only was he stunned into insensibility, but the wind was knocked out of him. He would not fight again for some considerable time.
Scarcely had they struck the lower ledge than Tarzan was upon his feet. He saw the monsters scrambling quickly toward him; he saw the wild-girl already reaching out to clutch him, and in the instant his plan was formed.
The girl was on the ledge below, reaching for one of his ankles to drag him down. He stooped quickly and seized her by the hair; then he swung her, shrieking and screaming, to his shoulder.
She kicked and scratched and tried to bite him; but he held her until he had carried her to a higher ledge; then he threw her down and made his rope fast about her body. She fought viciously, but her strength was no match for that of the ape-man.
The creatures scaling the cliff were almost upon them by the time that Tarzan had made the rope secure; then he ran nimbly upward from ledge to ledge dragging the girl after him; and in this way he was out of her reach, and she could not hinder him.
The highest ledge, that from which Rhonda watched wide-eyed the changing scenes of the drama being enacted below her, was quite the widest of all. Opening on to it was the mouth of a cave. Above it the cliff rose, unscalable, to the summit.
To this ledge Tarzan dragged the now strangely silent wild-girl; and here he and Rhonda were cornered, their backs against a wall, with no avenue of escape in any direction.
The girl clambered the last few feet to the ledge; and when she stood erect, facing Tarzan, she no longer fought. The savage snarl had left her face. She smiled into the eyes of the ape-man, and she was very beautiful; but the man's attention was now upon the snarling pack, the leaders of which were mounting rapidly toward this last ledge.
"Go back," shouted Tarzan, "or I kill your she!"
This was the plan that he had conceived to hold them off, using the girl as a hostage. It was a good plan; but, like many another good plan, it failed to function properly.
