But even then the Indians acted strangely. Heretofore, they had laughed and joked or had sung rollicking chanteys in unison to the strokes of their paddles, but to-day they were quiet, talking together in low tones, constantly edging the boat towards the center of the river, despite Colcord’s efforts and commands, and plying their paddles more vigorously than ever before.

“I believe there’s something afoot,” declared Mr. Thorne. “I’ve lived a long time among these people and I’m convinced they have a sixth sense--mental telepathy or something--by which they know intuitively when there is danger near and I’m beginning to think that there may be a Kenaima about.”

“Why don’t you ask them?” inquired Mr. Henderson.

“Torture wouldn’t force them to tell,” responded the explorer. “Even to mention the avenger by name is considered dangerous--I’m surprised that Joseph dared utter the word last night.”

“But if he’s only after one person, why should they he afraid?” asked Frank. “They know he’s not after them.”

“Very true,” replied Mr. Thorne. “But they fear that he may not have driven the spirit of vengeance from his body--if he’s killed his man--and that being the case he is liable to kill and attack any one.”

“Hmm, uncomfortable sort of chap to have at large in the bush,” commented Mr. Pauling. “Does that ever occur?”

“Yes, frequently,” said Mr. Thorne. “It may seem preposterous to us, but the Indians believe so thoroughly in their superstitions that if a Kenaima does not succeed in carrying out his entire purpose he goes crazy and does run amuck.”

“Ah, I understand, sort of auto suggestion,” remarked Mr. Pauling.

It was now time to think of stopping for the noonday rest and lunch and at Mr. Thome’s orders, Colcord headed the boat towards shore.
