"Und dis feller iss der same vay!" called Carl. "Look ad here, vonce!"

All eyes turned in the direction of the Dutch boy. He was sitting on his enemy's chest, holding him down, and there were dabs of brown pigment all over Carl's face. His hands were fairly coated with it.

"These savages have a yellow skin, Matt," said Glennie, "and it must be that they paint themselves a brown color when they go on the warpath."

"If what I have read is true," returned Matt, "there are no savage tribes at the mouth of the Amazon. All the Indians in these parts are at least half civilized."

"Then where did these rascals come from, and why have they attacked us in this venomous manner?"

"They came from that island where we cleared the propeller," said Matt.

"These are members of that gang?"

"Don't you recognize them, Glennie?"

"They all look alike to me. Of course, I suspected they were from the same tribe, but I didn't know they were the same men. There were five of them on the island."
