"Water!" groaned Overland.

"Water, eh? Well, crawl to it, you rat!"

Winthrop, his heart thumping wildly, followed the constable. So this was desert law? No word of warning or inquiry, but a hail of shots, a riderless horse,—two men stretched upon the sand and the burning sun swinging in a cloudless circle above the desolate silence.

"You seem to kind of recognize your friend now," sneered the constable.

That was too much for Winthrop's overstrung nerves. His pulses roared in his ears. With a leap he seized the constable's gun and twisted at it with both hands. There was an explosion, and Winthrop grinned savagely, still struggling. With insane strength he finally tore the gun from the other's grasp. "You're the only coward in this affair," he gasped, as he levelled the gun at the constable. That officer, reading danger in Winthrop's eye, discreetly threw up his hands.

"Good!" exclaimed Overland, sitting up suddenly. "That was risky, but it worked out all right. I had a better plan. You go set down, Billy. I'll see this gent safe toward home."

Winthrop laughed hysterically. "Why, you—you—you're a joke!" he cried. "I thought—"

"So did the little man with the pie-pan pinned on his shirt," said Overland. "You keep his gun. I got to see how bad the other gent's hit."

An hour later the constable of the desert town led his pony toward the railroad. On the pony was his companion, with both arms bandaged. He leaned forward brokenly, swaying and cursing. "I'll—get him, if it takes—a thousand years," he muttered.

"I reckon it'll take all of that," growled the constable. "You can have all you want of his game, Saunders,—I'm through."
