Morton put his hand on Charlie's shoulder.

"It's a real plucky bid, my boy, after what we've just seen; but do you think I could let you go? Why, you'd be cooked and eaten in no time."

"Hold on!" said Brown; "I'm full of ideas just now; let me think this one out; there's something in what Charlie says."

"Now, oracle, as soon as you're ready," returned Morton.

"Well, I may be right or wrong, but my notion is that Columbus does not want to eat Charlie. Why, they've got enough rations for a month. I think that they keep this old man as a sort of Fetich, and that Columbus and a few of the knowing old fellows see that he must soon die. Now they want Charlie to take his place."

Brown paused triumphantly.

"I verily believe you've hit it," said Morton. "You ought always to live here, considering the amount of intellect you are developing."

At this moment a renewed din once more pealed up from the cave, and the party crawled back to find out the cause. The gong-beaters, Columbus, and his privy councillors were parading the captives, and the spectators shuddered as they looked down upon hideous remains of the late feast scattered about the sandy floor of the cavern. This time a fine-looking young man was selected and marched up to the venerable figure on the stone. The gong-beaters fell back, and Columbus and his companions proceeded to smear the youth's forehead with red pigment, and marked the cabalistic white triangle on his breast. He was then led away to a dark corner out of sight of the watchers.

Brown muttered a deep oath.

"That's what has been puzzling me," he growled to Morton, "how they kept their numbers up; of course they recruit from the best-looking prisoners."
