A pause, while Schwandorf's cigar end glowed like a flaming eye.

"The Red Bones live well up the river," he began, abruptly. "Twenty-four days by canoe, five days through the bush on the east shore. That would bring you to their main settlement—if you were not wiped out before then. They're a big tribe, as tribes go. Ever been here before?"

"No. Not here," Knowlton told him. "I've been in Rio, and McKay here has knocked around in—"

A stealthy kick from McKay halted him an instant. Then, deftly shifting the sentence, he concluded, "—in a number of places."

"So." Another pause. "Then I should explain about tribes. Tribes here generally consist of from fifty to five hundred or more persons living in big houses called 'malocas.' Unless the tribe is very big, one house holds them all. There may be any number of malocas, the inhabitants of which are all of the same racial stock; yet each maloca is, as far as government is concerned, a tribe to itself, controlled by a chief. No maloca owes any duty to any other maloca. There is no supreme ruler over all, nor even a federation among them. They live merely as neighbors—distant neighbors. At times they fight like neighbors. You understand."

"'When Greek meets Greek—'" quoted McKay.

"Just so. When I say, then, that the Red Bones are a big tribe, I mean that there are about five hundred—maybe more—individuals in their main settlement. They live in huts, not in one big tribe-house like the Mayorunas. They are not Mayorunas, in fact; they paint differently, are darker of skin, and more cruel.

"The Mayorunas, by the way, are not so debased as you might think. Though cannibals, they do not kill for the sake of eating 'long pig,' like the cannibals of the South Seas. Neither do they eat the whole body. Only the hands and feet of their dead enemies are devoured. These are carefully cooked and eaten as delicacies along with monkey meat, birds, fish, and other things prepared for a feast in honor of a victory. The eating of human flesh seems to be symbolism rather than savagery. Furthermore, they do not range the jungle hunting for victims. They eat only those who come against them as enemies.

"So it is quite possible, you see, that strangers might go among them and escape death. It would depend largely on the ability of the strangers to convince the savages that they were friends. The difficulty is that the savages consider all strangers to be enemies until friendship is proved."

"A sizable difficulty," McKay remarked.
