Bry shook his head.

“All very wicked mans, Mars Sam,” he said. “Even in big storm, while we climb up to cave, Mars Daggett tell me to go behind Pete an’ push him off rock.”

“The villain!” I exclaimed, indignantly.

“He tell me if I not push Pete off, he kill me,” continued Bry, with a grin.

“What did you do?”

“When they run into cave, I run by it, an’ come here. That’s all, Mars Sam.”

“You did well, Bry. If they climb up here after you, we’ll fight them to the death.”

“No climb rock any more, Mars Sam,” said Bry, soberly.

“Why not?”

“See how rock tip? Only fly can climb rock now.”
