At last he dared to uncover his eyes again and once more fixed them on the toiling atom on the sunlit cliff face.

But now he burst out into tones of joy.

“Sanctissima Maria! See, he is almost at the summit. Oh, brave Gringo! Climb on. May your head be steady and your hands and feet nimble.”

The sweat was pouring down the Mexican’s face, his knees smote together and his hands shook as he stood like one paralyzed, stock still, watching the outcome of Jack Merrill’s fearful climb. His breath came fast and the veins on his forehead stood out like whip cords. As he watched thus his lips moved in constant, silent prayers for the safety of the young Border Boy.

At last he saw the infinitesimal speck that was Jack Merrill reach the summit of that frowning height. He saw the boy thrust his knife into his belt, and watched him place one hand on the ridge of the precipice and draw himself up.

The next instant the cliff face was bare of life. The fight with death had been won. But Alvarez as he saw Jack attain safety on the summit of the precipice sank back with a groan. The strain under which he had labored had caused the Mexican to swoon.

As he lay there perfectly still three figures appeared at the upper end of the valley in the direction of the Pool of Death. They began advancing down the valley just as Alvarez opened his eyes and staggered dizzily to his feet.
