The two females withdrew, and only one person now remained before Unicorn, and that was the feigned sorcerer. The two men examined each other attentively.

"Oh," the chief said, "what fortunate accident brings my father to my camp?"

"The messengers of Wacondah go whither he orders them without discussing his will," Nathan answered drily.

"That is true," the chief went on; "what does my father desire?"

"Hospitality for the night."

"Hospitality is granted even to an enemy in the desert; is my father ignorant of the customs of the prairie, that he asks it of me?" the chief said, giving him a suspicious look.

Nathan bit his lips.

"My father did not quite understand my words," he said.

"No matter," Unicorn interrupted him authoritatively; "the Great Medicine man will pass the night in the camp; a guest is sacred to the Comanches; only traitors, when they are unmasked, are punished as they deserve. My father can retire."

Nathan shuddered inwardly at these words, which apparently indicated that the sachem had his suspicions. Still, he shut up his fears in his heart, and continued to keep a good countenance.
