He was a short, rather stockily built man of middle age, and obviously, from his mahogany colored skin and lank black hair, a Mexican. He was dressed in a tattered shirt with a serape thrown about the neck to keep off the blazing rays of the sun. His feet were encased in a kind of moccasins over which spurs were strapped. Evidently, then, he had been mounted at some time—presumably recently, but where was his horse? How did he come to be wandering under the maddening heat of the sun over the vast alkali waste. But these were questions the answers to which had to be deferred for the present, for it began to appear doubtful if they had arrived in time to fan the wanderer's vital spark back into flame.
But at length their ministrations met with their reward. The man's eyelids flickered and a deep sigh escaped his lips. Before long they could press the water canteen to his mouth. He seized it with avidity and would have drained it.
"Only a little," cried Peggy; "I read once how a man, dying of thirst, was killed outright when he was given too much water to drink."
So Roy wrenched the canteen from the prostrated man's feeble grasp before he had drained more than a mouthful or two. But even that had revived him, and he was able to sit up and gaze about bewilderedly. All at once his eyes rested on Peggy, and he seemed to regard her as the means of his salvation from a terrible death on the alkali. Kneeling down he cried out in a pitifully cracked voice:
"You missie angel from heaven. Me Alverado your servant always. No go away ever!"
"By ginger, Peggy, you've made a conquest!" cried Roy, half hysterically.
Now that the strain of the struggle between life and death was over Peggy flushed and looked embarrassed. She was not used to the exaggerated character of the Mexican. But if she feared another outburst it did not come. Far too much exhausted to say more, Alverado—as he called himself—sank back once more on the alkali.
"Quick! Carry him to the aeroplane and get him into camp," cried Roy, raising the half-conscious Mexican's head. "You girls take his feet and we'll put him in the bottom of the chassis on those cushions."
Consequently, when the aeroplane once more took the air it was to fly lower than usual under its additional burden, but in the hearts of all three of its American occupants there rang the joy of having saved a human life from the unsparing alkali.
"Aunt Sally! Aunt Sally! Everything's all right and we've got a patient for you," was Peggy's rather uncomplimentary greeting as the aeroplane alighted and came spinning across the dusty expanse toward the willow clump.
