"This country was once oasis country," commented Yar Ali. "Allah knows how many centuries ago the sand took it, as the sand has taken so many cities in Turkistan."
They swung on like dead men in a gray land of death. The moon grew red and sinister as she sank, and shadowy darkness settled over the desert before they had reached a point where they could see what lay beyond the broken belt. Even the big Afghan's feet began to drag, and Steve kept himself erect only by a savage effort of will. At last they toiled up a sort of ridge, on the southern side of which the land sloped downward.
"We rest," declared Steve. "There's no water in this hellish country. No use in goin' on for ever. My legs are stiff as gun-barrels. I couldn't take another step to save my neck. Here's a kind of stunted cliff, about as high as a man's shoulder, facing south. We'll sleep in the lee of it."
"And shall we not keep watch, Steve sahib?"
"We don't," answered Steve. "If the Arabs cut our throats while we're asleep, so much the better. We're goners anyhow."
With which optimistic observation Clarney lay down stiffly in the deep sand. But Yar Ali stood, leaning forward, straining his eyes into the elusive darkness that turned the star-flecked horizons to murky wells of shadow.
"Something lies on the skyline to the south," he muttered uneasily. "A hill? I cannot tell, or even be sure that I see anything at all."
"You're seeing mirages already," said Steve irritably. "Lie down and sleep."
And so saying Steve slumbered.
The sun in his eyes awoke him. He sat up, yawning, and his first sensation was that of thirst. He lifted his canteen and wet his lips. One drink left. Yar Ali still slept. Steve's eyes wandered over the southern horizon and he started. He kicked the recumbent Afghan.
