The men behind saw it, too; and the brute who had fired the shot shouted to his companion, and then continued the pursuit.

The chase was all but over. The white horse struggled on gamely, but as it neared the gully where I lay the pace slackened ominously. Its rider looked back at her pursuers, and then across the ravine; and then, to my further amazement, I saw that she was no more than a girl in years—and a very pretty one, too; her face flushed with the excitement of the mad gallop, her eyes wide with alarm, and her features set with the courage of desperate resolve.

Her pursuers realised her plight; and being now sure of capturing her, slung their guns and rode down the ugly path very cautiously.

I made ready to take my share in the business. I had my revolver in my hip pocket, and drew it out, but did not show myself. My intention was to let her pass and then get between her and the men. But her horse was done. The bullet had evidently found the artery, for the blood was spurting out fast; and just before she reached the spot where I crouched the poor beast lurched badly and half sank on its quarters. The rider had only time to jump cleverly and quickly from the saddle when the end came, and the gallant little horse rolled over.

She must have given up all for lost then; but she showed no sign of faltering courage. One swift, desperate glance round she gave, as if in search of some chance of escape, and I saw her face was pale and set, but full of determination. Then, drawing a dainty little stiletto from her dress, she stood at bay behind the body of the dying horse with a calmness all eloquent of pluck and nerve.

Meanwhile, with Chris at my heel, and keeping as much as possible under cover, I crept forward until I was opposite to her. The men dismounted when they were still some fifty yards or so above her, and they were rushing forward to close upon her when I showed myself, with Chris growling ominously at my side.

The surprise caused by my unexpected appearance gave me a moment’s advantage.

“Have no fear. The dog will guard you,” I called to her as I passed. “Guard, Chris, guard, good dog,” I told him; and instantly understanding me, he ran to her side.

“Thank God,” I heard her murmur as I sprang toward the men, with my revolver levelled at them.

“You may give it up,” I cried; but that was not their view. One of them swung his gun round on the instant, and was in the act of levelling it at me when I fired, aiming low, and shot him in the leg, bringing him to the ground.
