"No!" he disputed. "Not without a try for life, anyhow! Merry, sling a tourniquet! Quick!"

Knowlton jumped to the side of Yuara, tied a handkerchief above the elbow, twisted it tight. McKay whipped from a pocket a keen-bladed knife. In one swift ruthless slash he laid open the arm from elbow to knuckles.

"Keep that tourniquet tight!" he snapped. "If the blood once gets past it he's gone. Tim, get out the salt bag! Lourenço, tell this fellow to breathe deep and keep it up!"

While Tim burrowed into his pack for the salt, Lourenço spoke, as much for the benefit of the other tribesmen as for that of Yuara; for the three Mayorunas stood in ominous silence, watching the outrush of blood caused by the knife of the white man.

"The white man of the black beard, who is very wise, will save Yuara to draw many a good bow if Yuara will do as he says. Let Yuara breathe deeply, that the spirit of life remain in him to fight against the demon of death. Even now the poison rushes out of the arm of Yuara."

"Yuara cannot live," was Yuara's cool reply. "Where once the poison has entered, there follows death."

"Is Yuara then a coward, that he will die without a fight? Then he is no Mayoruna, for no Mayoruna is a coward. Let Yuara die if he will. His comrades shall carry to their maloca the tale that, although the white man would have saved him, he died like an old woman, because he had not the will to live!"

Fire shot into the eyes of the prostrate man. He ground his teeth and struggled to rise and throttle the insulting Brazilian.

"No, not that way," Lourenço went on at once. "Yuara can fight the death demon only by drawing into himself the air in which is the spirit of life. The wise white man has stopped the poison at the place where the cloth is tied, and he knows the air spirits will help Yuara if Yuara will breathe deep and long. If he will not, then the white man's medicine cannot save him. Yuara's life or death is in his own hands."

In his heart Lourenço had faint hope that the injured man would live. But he knew the rest of the cannibal tribe must soon hear the tale of this incident from the three now present, and he was preparing an excellent excuse for the failure of McKay to save him. Whether Yuara lived or not, the Mayorunas now would know that the whites had done their utmost for him, and that very fact might make a vast difference.
