Miss Prescott threw up her hands and old Mr. Peter Bell hastened from amidst his beloved horses.

"Everything's all right but you've got a patient!" cried the New England lady, who looked very prim and unwesternlike in a gingham gown and sun bonnet to match.

"No time for explanations now," cried Roy. "Come on, Mr. Bell, and help us get our sick man out and then we'll tell you all about how we found Jimsy and Mr. Bell at the mine."

With Mr. Bell's assistance it did not take long to transfer Alverado from the aeroplane to a cot, and Miss Prescott, who, as Roy said, would "rather nurse than eat," ministered to him to such good effect that by nightfall he was able to sit up and tell his story. In the meantime the excited youngsters had related their narratives, which Miss Prescott interrupted in a dozen places by: "Land's sakes!" "Good gracious me!"

"Oh, what a dreadful country!" and much more to the same effect.

All the time he was relating his story Alverado kept his eyes fixed on Peggy's face, with much the same expression as that worn by a faithful spaniel. At first this fixed gaze annoyed the young girl not a little, but soon she realized that it was entirely respectful and meant as a tribute, for the Mexican evidently regarded her as his rescuer in chief.

Alverado's story proved vague and sketchy, but he could not be induced to enlarge upon it. In brief his tale was that some years before, when crossing the desert on his way from a mine he owned, he had been attacked by a band of highwaymen. They had wrecked his wagon and murdered his family, who were traveling with him. They had attacked him because of their impression that he was carrying much gold with him, whereas, in reality, he had secured nothing but a living from his desert mine. In their rage at being thwarted, the miscreants had wiped out the Mexican's family and left him for dead with a wound in his skull.

But a wandering band of Nevada Indians had happened along while the Mexican still lay unconscious and, reviving him, carried him with them over the border into California. He had parted from them soon after and drifted down into Mexico. In time he accumulated a small fortune, but the thought of the wrong he had suffered never left his heart. At last his affairs reached a stage where he felt justified in returning to Nevada to try to find some trace of his wrongers, and demand justice. He had set out well equipped, but, a few days before the young aviators encountered him, his water burro had stumbled and fallen, and in the fall had broken the water kegs it carried. From that time on his trip across the alkali had been a nightmare. First his pony had died, and then his two remaining pack burros. He had obtained a scanty supply of thirst quenching stuff from the pulpy insides of cactus and maguey leaves, but when the aviators had discovered him he had been in the last stages of death from thirst and exhaustion—the death that so many men on the alkali have met alone and bravely.

"Do you know the name of the men who attacked you and treated you so cruelly?" asked Peggy, breaking the tense silence which followed the conclusion of the Mexican's dramatic narrative.

A dark look crossed the man's swarthy features.
