“Have you seen anything to make you fear?” Ferdinand asked, gazing at him keenly.

Pedro’s voice was low.

“No,” said he. “Naught have I seen. But I feel it. Here.” And he placed a hand upon his breast. “There is some evil in these forests.”

“Here, here,” said Frank, interrupting. “This search must not be delayed. I’ll stay.”

“And I’ll stay with you,” said Bob. “Three’s enough for the search.”

Frank threw him a grateful look, knowing well that it was consideration for him which prompted his big chum’s proffer. Nevertheless, he started to protest, but Jack interrupted.

“Good idea,” he said. “Well, let’s go. If we get into any sort of trouble, we’ll fire three times in rapid succession. As for guide, if we follow the stream, we cannot go astray.”

He did not put it into words, but Pedro’s premonition of evil had effected him, coming as it did in confirmation of his own vague yet powerful fears. He wanted to plunge ahead without more delay. Therefore, with Ferdinand and Pedro at his heels, he set off rapidly down the stream.

As their friends disappeared, Frank, looking thoughtful, turned to his chum.

“Bob, I don’t know what to make of all this,” he said. “But I have a hunch it would not be a bad idea for us to keep some sort of watch, instead of merely dozing. So I’ll take the first watch for an hour, and then you can relieve me.”
