"Because then we could have brought company with us. Senhores, guess what the barred house holds."

"Well?"

"Women of the Mayorunas! Girls stolen from Monitaya and other settlements!"

"Jumping Judas!" ejaculated Knowlton. "Are you sure?"

"Sure, comrades! These foul Red Bones are the men who have been lurking around the Mayoruna tribe houses and capturing girls who went into the bush. They have taken the prisoners to the water, where the trails always were lost and where they could find hiding places until night, then drive their canoes past the clearings and get out of that country. So there must be some water connection by which these men travel, and by which we too can travel. If we go downstream we are almost sure to find it by daylight."

"But why—what's the idea of their stealing the girls? For victims? If so, how are the girls still alive?"

"Do you not see, senhor?" Pedro broke in, impatiently. "Did not Umanuh ask if we would pay more than the other Blackbeard for the Raposa? What other Blackbeard?"

"Schwandorf!" the Americans blurted, simultaneously.

"Not so loud! Schwandorf, of course! Umanuh works with the German. He catches girls by stealth and sells them to the German to add to his slave gangs. While the Mayorunas all blame the Peruvians for the disappearances, Umanuh works unsuspected. He is holding these women until Schwandorf comes again—and it may be that Schwandorf is not far off at this moment. Now that we have come seeking the wild man, Umanuh at once thinks of selling him also; and he wonders whether we or Schwandorf will pay the more for him."

"By thunder! I believe you're right!" Knowlton coincided. "He's stalling for time, holding us here while Schwandorf comes up, I'll bet. No wonder he and his men are wary of the Mayorunas—they thought we'd come to snoop around and catch 'em with the goods. You fellows must have done a mighty slick job to find out this stuff without getting caught. Isn't the house guarded at night?"
