tance of miles, is the constant undertone.
Roberts heard all these, but it was sight, not sound which absorbed him. Flitting scarecrows from the caves might approach soundlessly over the sand, but he did not believe they could reach him unseen.
He had not calculated upon the sand and dust. A squall came up, beating upon the watchers with a fusillade of fine, choking particles, and raising a screen before Roberts' eyes. In the midst of this he heard dry coughs. Someone was out there, approaching with the shielding sand!
Still the watcher, alternately brushing grains of sand from his nostrils and eyes and peering along the barrel of his rifle, found no target. A sudden notion came to him that the marauders now were inside his camp, about to leap upon him.
He dropped the rifle, and seized two revolvers, shaking the sand and dust out of their muzzles.
As suddenly as it had risen, the veil lifted. Roberts, peering out eagerly, saw only a single bent, stumbling figure—a man who fell to his knees, head almost in the sand, and tried to arise. . . . A snap shot from the ready revolver stretched him flat, his breath leaving in a sharp exhalation like air drawn from a pneumatic tire.
In that instant Roberts stiffened. From out there ten paces had come a gasping sound. It was the wounded man, the desert rat.
"G'bye!" he wheezed. "G'bye. . . never come . . . . back . . . . now . . . ."
The words were English!
SELWYN ROBERTS, waiting only to draw on heavy gloves of Llama hide, ran, crouching, to his fallen adversary.
Catching the shrunken, bowed figure beneath the arms—arms which at biceps gave only a pinch of flesh and bone into his grasp—he scurried back. Then, stationing the Chinese in a semi-circle further out, so that no marauders might enter without encountering opposition, he turned to the fainting figure of his victim.
Screening electric torch by flaps of jacket, he looked down at the man. He saw a yellowed, meager face, with eyes that had become long and narrow from much squinting in the desert. The man, unconscious now, had his head shaved except for the circle and queue usual among natives of Inner Mongolia. Except that no sign of leprosy showed, he looked the part of a desert exile. Tearing away his black cotton shirt, however, Roberts saw, with a sinking heart, that the intruder's skin was as white as his own!
Desperately, casting aside all caution in use of the flash-lamp, Roberts worked. He found the wound, a gaping hole from soft-nosed bullet, which lay just beneath the stretched ridge of the left clavicle. Probably the bullet had punctured the top of the man's lung. This was rendered plausible by flecks of reddish foam gathering in his mouth corners.
Roberts stanched the external bleeding, and fetched whisky from his personal pack. Forcing three tablespoonfuls of the potent fluid between the man's lips, he held forward the lolling tongue which would have shut off respiration. Ten seconds later the patient squirmed, trying to sit up. Roberts, a solicitous tyrant, held him fast.
"Not dead yet?" queried the man, ending his sentence in a ghastly cough. "What the hell. . . .?" He choked, spitting sidewise to the sand.
"No, you're not dead, and you're not going to die!" replied Roberts with forced calmness. "Take it easy. You're among friends."
"Oh yes, I'll die," stated the man with conviction. "Where am I? Who are you? I Ch'ueh shīh hsiang. . . ." His speech trailed off into
