The wound in his head was bleeding now under his tremendous exertions, and he began to grow dizzy and faint. But, although his strength was ebbing, his heart was as high and his spirit as undaunted as ever. He would never surrender. As a last resource he had his revolver, and, if he had to die, he would take some of the outlaws with him. The thud of hoofs was nearer now, and bullets began to whiz past him. A voice that he knew was that of the leader of the gang shouted to him to halt. Before him was a thinning of the woods that indicated open country. On a level course they could never get him. His second wind was coming back and he would distance them yet. On, on, he went, running like the wind.

A few rods ahead the trail bent round in a sweeping curve, and as Bert approached it on flying feet, he heard horsemen coming from that direction. With a groan he halted. They had him surrounded, then. He had no chance. The game was up. He drew his revolver and dropped on his knee to aim.

And then round the curve with a rush and a roar, riding like fiends, came Melton, Dick and Tom, with twenty cowboys at their back.

There was a wild whoop when they caught sight of Bert, and his comrades flung themselves from the saddle and rushed toward him. Melton, without dismounting, reached over and gave him a bear grip that said more than words. Then he straightened up and rode on at the head of his men to meet the rustlers.

The latter, however, did not await his coming. They broke and ran, bending low over the necks of their horses. But Melton's blood was up and he rode them down relentlessly. Rifle and revolver shots merged into one crackling fusillade. The cornered outlaws fought to the last ditch when overtaken, and no one asked for quarter. And when at last the fight was over, five, including the captain, lay stretched lifeless upon the ground. One, by hard riding and his knowledge of the country, had escaped, and "Red," still looking dazed and foolish, was a prisoner.

The cowboys were for stringing him up on the spot, but Bert, who had swung up behind Dick and been in at the finish, pleaded hard that his life might be spared.

"You win," conceded Melton. "You've done too much for me to refuse you anything. We'll turn him over to the sheriff, and he'll have all the chance that's coming to him, which, between you and me, I think is mighty little."

Then he turned to Pedro, who, as Bert now noticed for the first time, was sitting tied upon his horse and guarded by two of the ranchmen.

"Cut his ropes," he commanded, "and turn him loose. I promised the hound his life if he led me to the rustlers' camp, and I keep my word."

Melton gathered his force together and they took up their march for home, jubilant at the success of the expedition.
