He had seen strange things during the last few days, and just because the rifle and other objects had turned out to be real was no reason that he should absolutely trust his eyes in this particular instance. There was a limit, which in this case was Apaches in full war dress; so he arose swaggeringly and fired at the last, and saw the third from the last slide limply from his horse. As the rest paused and half of them wheeled and started back he rubbed his eyes in amazement, damned himself for a fool and sprinted for the mesa wall, up which he climbed with the frantic speed of fear. He was favored by the proverbial luck of fools and squirmed over a wide ledge without being hit. There was but one way to get him and he knew he could pick them off as fast as they showed above the rim. He rolled over and a look of mystification crept across his face. Digging into his pockets to see what the bumps were, he produced the mirror and a flask. The former he placed carelessly against the wall and the latter he raised hastily to his lips. The mirror glared out over the plain, its rays constantly interrupted by Mr. Purdy’s cautious movements as he settled himself more comfortably for defense. A bullet screamed up the face of the wall and he flattened, intently watching the rim. Chancing to glance over the plain, he noticed that the wagon was still moving, but slowly, while far to the south two horsemen galloped back toward the mesa on a wide circle, six Apaches tearing to intercept them before they could gain cover. "I was shore wise to leave th’ schooner," he grinned. "I allus know when to jump," he said, and then swung the rifle toward the rim as a faint sound reached his ears. Its smoke blotted out the piercing black eyes that looked for an instant over the edge and found eternity, and Mr. Purdy grinned when the sound of impact floated up from below. "They won’t try that no more," he grunted, and forthwith dozed in a drunken stupor. A sober man might have been tempted to try a shot over the rim, and would have been dead before he could have pulled the trigger. Mr. Purdy was again favored by luck. Leaving two braves to watch him, the other two searched for a better way up the wall.
