“What’s the idea?” asked Glenn.

“Do they want to eat us?” asked Jimmie.

“Some of the wild tribes living near the head waters of the Amazon,” Bixby explained, “are crazy over the capture of white men. They are said to march them back to their own country in state, and to inaugurate long festivals in honor of the victory. And during the entire festival,” Bixby went on, “the white prisoners are subjected to tortures of the most brutal description!”

“Say,” giggled Jimmie, giving Carl a dig in the ribs with his elbow, “let’s take the train for Guayaquil to-morrow morning! I don’t think it’s right for us to take chances on the savages having all the fun!”

“As between taking the first train for Guayaquil and taking a trip through the air to the old camp to-night,” Bixby laughed, “I certainly advise in favor of the former.”

“Aw, that’s all talk,” Ben explained, as Bixby, after promising to look about in the morning for oiled-silk and provisions, locked his place of business and started toward the hotel with the boys.

“What do you say to it, Carl?” Jimmie asked, as the two fell in behind the others.

“I’m game!” replied Carl.

“Then I’ll tell you what we’ll do!” Jimmie explained. “You and I will get a room together and remain up until moonrise. If the sky is clear of clouds at that time, and promises to remain so until morning, we’ll load ourselves down with all the guns we can get hold of and fly out to the old camp. It’ll be a fine ride, anyway!”

“Pretty chilly, though, in high altitudes at this time of night,” suggested Carl. “I’m most frozen now!”
