“That's what it is!” Mr. Hennage walked to the end of the porch. He was just a little excited. “It's all off with the hobo” he continued. “I know the man that's using that automatic, and he can shoot your eye out at a hundred yards. I saw him ridin' in just as I left the eatin' house.”

“He must have been movin' to get down there in such a hurry. What's a man on horseback doin' chasin' hobos across a web of railroad tracks, an' if he was headed south, seems to me he'd have laid over for supper—”

But Harley P. had a flash of inspiration now. “Come on, O'Rourke” he shouted, and made a flying leap off the saloon porch. Borax followed, and the two raced down the street at top speed—which, in the case of Mr. Hennage, owing to his weight and his bow-legs, was not remarkable. Borax easily outdistanced him.

Meanwhile, a rather spectacular panorama had been unfolding itself back of the string of box-cars. Guided by Donna's screams, Bob McGraw sent his horse away at a tearing gallop, lifting him in great leaps across the maze of railroad tracks, and in a shower of flying cinders brought him up, almost sitting, in the little foot-path between two lines of track. Almost under Friar Tuck's front feet, Donna was struggling in the grasp of three ruffians, one of whom was endeavoring to tie a handkerchief across her mouth. The velocipede had been derailed by means of a car-stake placed across the track.

Bob McGraw's long gun rose and fell three times, and at each deadly drop a streak of flame punctured the moon-light. The three assailants went down, shot through their respective legs—which remarkable coincidence was not a coincidence at all, but merely a touch of kindly consideration on the part of Bob McGraw, who didn't believe in killing his man when wounding him would serve the same purpose.

As the three brutes dropped away from her the man from Owens river valley lowered his weapon, and Donna, pale, terrorized and disheveled, reeled toward him. He swung his horse a little, leaned outward and downward, and with a sweep of his strong left arm he lifted her off the ground and set her in front of him on Friar Tuck's neck, just as one of the wounded thugs straightened up, cut loose with his bulldog gun and shot Bob McGraw through the right breast.

Donna heard a half-suppressed “Oh!” from her deliverer, and felt him sway forward a little. Then, seeming to summon every atom of grit and strength he possessed, he whirled his horse, scuttled away around the rear of the box-car, out of danger, and set Donna on the ground.

“Wait here” he commanded, through teeth clenched to keep back the blood that welled from within him. “I was too kind—to those hounds.”

He rode back and finished his night's work. War-mad, he sat his horse, reeling in the saddle, and emptied his gun into the squirming wretches as they sought to crawl under the car for protection.

Donna was terribly frightened, but she was the last woman in the world to go into hysterics. She realized that she was saved, and accordingly commenced to cry, while waiting for the horseman to reappear. A minute passed and still he did not come, and suddenly, without quite realizing what she was doing or why she did it, the girl went back to the scene of the battle to look for him. She was not so badly frightened now, but rather awed by the silence, Donna was desert-bred, and in all her life she had never fainted. For a girl she was remarkably free from “nerves,” and she had lived too long in San Pasqual to faint now at sight of the three still figures huddled between the ties, even had she seen them; which, she had not. All that Donna saw was a roan range pony, standing quietly with drooping head, while his master sprawled in the saddle with his arms around his horse's neck. Donna went quickly to him, and when the moon came out from behind a hurrying cloud she was enabled, with the aid of the ghastly green glare from a switch lantern which shone on his face, to observe that he was quite conscious and looking at her with untroubled boyish eyes.
