The boy closed his eyes and tried to compose himself to slumber. Before long he actually did doze off and lay in that state while the long hours dragged slowly by. Wandering William had not reappeared, and Peggy wondered in a dull, vague sort of sort of way if he ever would come back. Perhaps he had deserted them, she thought. But, even this reflection brought no poignant sensation of despair. The girl had sunk into a sort of apathy in which nothing' seemed to matter much. Only she fairly ached with thirst. But Roy would awake presently and want water. The little they had must be saved for him.
And so the hours wore on and the sun marched blazingly across the sky. It was mid-afternoon, and Roy had not awakened, when Peggy was startled from her gloomy thoughts by a loud hail.
"Hul-lo!"
Springing to her feet she looked across the desert. On the summit of a distant earth wave she saw the figure of Wandering William. He was gesticulating frantically and shouting something. He had his hands to his mouth, funnelwise, to make the sound carry better.
What was it he was crying out? It sounded like—yes, it was:
"Water! I've found it! Water!"
Peggy hastily snatched up the two buckets with which the aeroplane was equipped, and hurried toward the distant figure. She reached Wandering William's side in quicker time than she would have thought possible, such was the stimulating effect of the glad news. The strange "professor" said not a word, but took her by the hand and began striding in great steps across the sandy dunes.
They had walked about a quarter of a mile when they reached a spot where yuccas and prickly desert plants of different varieties grew thickly. At the bottom of this desolate little valley was a pool on which the sunlight shone glitteringly. It was shallow and warm, and the color of rusty iron, but it was water.
Taking the folding tin cup that Wandering William produced from one of his pockets, the girl drank eagerly. Never had sparkling spring, water in the fruitful Eastern country tasted half so good as that tepid, dirty alkaline stuff that Wandering William had so providentially stumbled upon.
"How did you find it?" gasped Peggy.
