“But the Gapo?” interrupted the ex-miner, observing that the expressive look of uneasiness still clouded the brow of the Mundurucú.

“It’s the Indian name for the great inundation,” replied Richard, in the same tranquil tone. “Or rather I should say, the name for it in the lingoa-geral.”

“And what is there to fear? Munday has frightened us all, and seems frightened himself. What is the cause?”

“That I can’t tell you, uncle. I know there are queer stories about the Gapo,—tales of strange monsters that inhabit it,—huge serpents, enormous apes, and all that sort of thing. I never believed them, though the tapuyos do; and from old Munday’s actions I suppose he puts full faith in them.”

“The young patron is mistaken,” interposed the Indian, speaking a patois of the lingoa-geral. “The Mundurucú does not believe in monsters. He believes in big serpents and monkeys,—he has seen them.”

“But shure yez are not afeerd o’ them, Manday?” asked the Irishman.

The Indian only replied by turning on Tipperary Tom a most scornful look.

“What is the use of this alarm?” inquired Trevannion. “The galatea does not appear to have sustained any injury. We can easily get her out of her present predicament, by lopping off the branches that are holding her.”

“Patron,” said the Indian, still speaking in a serious tone, “it may not be so easy as you think. We may get clear of the tree-top in ten minutes. In as many hours—perhaps days—we may not get clear of the Gapo. That is why the Mundurucú shows signs of apprehension.”

“Ho! You think we may have a difficulty in finding our way back to the channel of the river?”
