It was a minute to shake nerves of steel. They could hear the sound of voices, an echo of jubilant laughter, the sound of iron shoes striking stones in the trail. Then some one shouted:

“Oh, you, Buck!”

The program might have gone through as arranged, but for an unlooked-for factor in the proceedings. Buck let out a shout of warning to his trapped friends. Almost at the same instant the butt of Farnum’s revolver smashed down on his head; but the damage was already done.

Bellamy and his friends swarmed out like bees. The outlaws were waiting irresolutely—some mounted, others beside their horses. Among them were two pack horses.

“Hands up!” ordered the mine owner sharply.

The answer was a streak of fire from a rifle. Instantly there followed a fusillade. Flash after flash lit up the darkness. Staccato oaths, cries, a moan of pain, the trampling of frightened horses, filled the night with confusion.

In spite of the shout of warning, the situation had come upon the bandits as a complete surprise. 331 How many were against them, whether or not they were betrayed, the certainty that the law had at last taken them at a disadvantage—these things worked with the darkness for the posse. A man flung himself on his pony, lay low on its back, and galloped wildly into the night. A second wheeled and followed at his heels. Hank Irwin was down, with a bullet from a carbine through his jaw and the back of his head. A wild shot had brought down another. Of the outlaws only MacQueen, standing behind his horse as he fired, remained on the field uninjured.

The cattlemen had scattered as the firing began, and had availed themselves of such cover as was to be had. Now they concentrated their fire on the leader of the outlaws. His horse staggered and went down, badly torn by a rifle bullet. A moment later the special thirty-two carbine he carried was knocked from his hands by another shot.

He crouched and ran to Irwin’s horse, flung himself to the saddle, deliberately emptied his revolver at his foes, and put spurs to the broncho. As he vanished into the hills Bob Farnum slowly sank to the ground.

“I’ve got mine, Bellamy. Blamed if he ain’t plumb bust my laig!”
