"What is the matter?" asked Shrahegan anxiously.

"A high fever."

"Not an evil spirit?"

"The only evil spirit," continued Keith, "is the one who has increased the fever by vile medicine and terrible noise."

"What, the Medicine Man?"

"Yes. He soon would have made an end of your brother."

A fierce look came into Shrahegan's face, and he made a move as if to leave the building. Keith laid a restraining hand upon his shoulder.

"Stay," he said. "Don't do anything rash. I want your help. We must remove the lad to a quiet lodge, and I shall try to undo the harm which has been done. It is the only way to save his life."

Shrahegan looked intently into the missionary's face, as if to fathom the depth and strength of his mind.

"Does my pale-face brother know?" he asked, "the risk he is running? Does he know that the wrath of the Medicine Man is upon him? that the Indians are very angry, and, if the boy die, the pale-face will die too?"
