Then he knew; saw it all as clearly as though he had witnessed it—the ambushment in the blinding sandstorm; the terror-stricken Waco; the frightened ponies; the lunging and swaying buckboard. And Pat, left for dead, but who had dragged himself from the roadway in dumb agony.

The dole of light from the sinking sun was gone. Waring's hands came away from the opened shirt shudderingly. He wiped his hands on the sand, and, rising, ran back to Dex. He returned with a whiskey flask. Pat was of tough fiber and tremendous vitality. If the spark were still unquenched, if it could be called back even for a breath, that which Waring knew, yet wanted to confirm beyond all doubt, might be given in a word. He raised Pat's head, and barely tilted the flask. The spirit of the mortally stricken man, perchance loath to leave such a brave hermitage, winged slowly back from the far shore of dreams. In the black pit of the arroyo, where death crouched, waiting, life flamed for an instant.

Waring felt the limp body stir. He took Pat's big, bony hand in his.

"Pat!" he whispered.

A word breathed heavily from the motionless lips. "You, Jim?"

"Yes! For God's sake, Pat, who did this thing?"

"Brewster—Bob. Letter—in my coat."

"I'll get him!" said Waring.

"Shake!" exclaimed the dying man, and the grip of his hand was like iron. Waring thought he had gone, and leaned closer. "I'm—kind of tired—Jim. Reckon—I'll—rest."

Waring felt the other's grip relax. He drew his hand from the stiffening fingers. A dull pain burned in his throat. He lighted a match, and found the message that had lured Pat to his death in the other's coat-pocket. He rose and stumbled up the arroyo to his horse.
