It was as if he could bear the idea of leaving his mountains and valleys and their riches to any other race than the one which had broken the empire of its ancient kings and destroyed the temples of the Aztec gods.

The Texans could also see more clearly now the grand height of the mountain chain into which they were climbing. They were evidently in a pass, partly natural and partly artificial. In places which would otherwise have been difficult the narrow roadway had been solidly constructed of massive stonework, for the greater part unhewn. There had been excavations also, but before long Joe was justified in remarking,—

"I say, colonel, this might do for mules, but it won't for mustangs. I'd rather go afoot."

He sprang to the ground as he spoke, and his comrades followed his example. Well they might, for at their right arose an almost perpendicular cliff, while at their left the side of the mountain went down, for hundreds of feet, without a tree or a bush to prevent man or horse from rolling the entire descent.

"How far have we now to go?" asked Bowie of his guide. "Red Wolf, hold on."

"Red Wolf find road," came back in Lipan-Spanish. "Big Knife bring old man. Tetzcatl heap dead."

"Pitch ahead, then!" exclaimed the colonel. "Boys, wait here with the critters. I'll go on and find the place. The boy can come back after you."

"All right, colonel," replied Jim. "He won't last long now."

"On! on!" exclaimed Tetzcatl, his fierce, black eyes burning with the fire of the fever which had set in upon him, caused by his hurts. "We are at the door! I will die in the house!"

He was very weak and in pain, but at the end of a hundred yards more of that steep and dangerous pass he halted his mule, slipped off to the ground, and actually stood erect.
