"Stay here," he said. "No Spaniard ever entered the last house of Huitzilopochtli. I go on!"

He turned, bracing himself with all his remaining strength, and went forward as if he believed that his injunctions had been obeyed.

"Fever crazy," said the colonel, in a low voice. "Keep just behind him. If we can follow without his knowing."

That was by no means difficult, for he did not turn his head, and there were many bushes, but it was best to let him keep a number of paces in the advance.

It was a winding pathway as well as steep. There were sudden turns around rocky projections, and now the gorge at the left was deeper and more terrible to look down into.

"What?" exclaimed Bowie, as he and his boy companion turned one of these corners. "Where is he? Did he tumble off the path? There isn't a trace of him!"

Vacant indeed was the narrow way before them, but Red Wolf sprang forward. The mountain-side above was not perpendicular at this point and there were bushes.

"Too much heap bush," said Red Wolf. "Track rabbit into hole. Ugh!"

He parted the luxuriant growth as he spoke and uncovered something plainer than a rabbit-track.

"Go ahead!" said the colonel. "Don't make a sound. He was trying to get away. He never meant to show it to us at all. Thunder! A man might hunt for this a hundred years and never find it."
