"About the time that Christopher Columbus was paddling to America," replied Leith. "There are no natives on the Isle of Tears now. Soma is speaking of a time when these islands were inhabited."

The Professor gurgled like a drowning mule. "This is a most interesting morsel of information," he murmured. "Hand me my camera, Barbara; I wish to take a snapshot of the place."

The delay irritated Leith, but he kept his temper in check while the Professor fussed and focussed to get a good view of the spot.

"The old fool should be in a padded cell," growled Holman. "He's so busy digesting that tale that he's not thinking of the dangers of this path. I'm going to speak to him aside."

"I hope you have better luck than I had," I whispered. "I bullied him as we were climbing the slope, and I believe he complained of me to Leith. He sees a mental picture of himself with bay leaves on his brow, and he wouldn't consider the nerves of twenty daughters."

I was right in my prophecy. When Holman approached the old maniac he ruffled up like an angry porcupine, and he screeched out his opinion concerning people who would not mind their own business.

"You're the second person who has kindly informed me what I should do," he exclaimed. "And who are you, sir? You have no standing with this expedition! This is a scientific exploration party, but it seems to me that a number of busy-bodies have pushed their way into it. I shall ask Mr. Leith if he cannot stop this interference!"

Leith listened till the Professor had finished speaking, then he turned savagely upon Holman. "I've given you one chance," he roared, "and you don't seem to profit by it. Now I'm not going to speak again! If I have to tell you to keep your finger out of this pie on another occasion, you'll go back to the yacht, and you'll go back without provisions, do you understand?"

The youngster was not lacking in courage, and he stood up boldly as the bully screamed out his threats.

"I won't go back," he said quietly. "At least I won't go back alone."
