"What is that to you?" he blustered roughly, thinking to beat her down; perhaps to kill her outright with cruelty. "This is my wife!"

"Oh, no! no!" whispered Natalie, sick with the sight of so much misery.

It is doubtful if the girl heard her. She tottered forward; and seized and clung to Mabyn's arm. Her breast was heaved on hard, quick pants like a wounded animal's; and her eyes were as frantic, and as inhuman.

"'Erbe't, who am I?" she breathed.

Mabyn, seeing that Natalie heard and understood, beside himself, and reckless with rage, flung out his arm, throwing her heavily to the ground. "You! damn you!" he cried. "You're just my——"

Natalie, with a low cry of horror, instinctively clapped her heels to her horse's ribs, and set off down the hill. Garth wheeled after her.

"Oh, stay—stay and help her!" she gasped.

"You come first!" said Garth grimly.

Mabyn, as Natalie turned, sprang after her; and running desperately, managed to cling to her stirrup. Casting off the last vestiges of manliness he wept and prayed her to wait for him. Her horse, Caspar, kicked out wildly, and struck him off. He lay on the ground sobbing and cursing; striving to drag himself along with clawing hands.

Just before they gained the watercourse, Garth looked over his shoulder; and his heart leapt into his throat. The brown woman was reaching for Mabyn's rifle. He shouted a warning; and desperately strove to throw his horse behind Natalie. But it was too late. Hard upon his voice, the shot rang. A strange, low cry broke from Natalie; and she reeled in her saddle. Garth, spurring ahead, grasped Caspar's bridle, and caught her from falling. A pang, far more dreadful than the hurt of a bullet, smote his own breast.
