Following an undeviating line, it left him far behind, diminished to a speck, and disappeared. The sound of it lingered when he could see it no longer.
His breath came quickly, spasmodically, through parted lips; his throat was tight, and his heart pounded. The staggering surprise of what he had seen and heard left him incapable of thought. His mind was a racing turmoil of questions. His contentment, his resignation were gone—destroyed in a moment; and in their place rose a great uneasiness.
The return of Hope, to a man who has definitely put it away from him, is a joy closely akin to pain in its intensity. His whole body shook as he struggled with the sand, attempting to rise.

The great question was where—and how—to go. He must go somewhere. Only motion would satisfy his craving for accomplishment of some sort. He would get no help on this great, sterile plain. He had no guarantee that another of the flying machines would come near him, and even if it did there was not much hope of attracting its attention. No, he must move....
