“What chart?” queried the master of the Golden Eagle.

“The treasure chart those four Englishmen had,” answered Dave. “Now what made them come here with it and tear it to pieces?”

“Hum!” mused the captain. “One of two things would make ’em do that, lad. Either they got the treasure and had no further use for the map, or else they found the whole thing was a fake and in their rage they tore the map to shreds.”

“They must have gotten the gold!” murmured Roger and Phil.

“No, I think they got fooled,” said Dave.

“The question is, if those Britishers were here, where did they go to?” asked the captain.

“Let us call,” suggested Dave. “They may be in some part of this cave where they couldn’t hear the shots from my gun.”

All called out several times, and listened intently for a reply.

“Hark! I hear something!” cried Roger. “Listen!”

They strained their ears, and from what appeared to be a great distance they heard a human voice. But what was said they could not make out.
