“There, I can just begin to see them through the trees and brush yonder, Dick; and, as we believed, they have some human being treed, or else are trying to force conclusions with a panther, which would be a strange thing, to be sure.”

“We’ll soon know,” the other whispered, “for it’s only a little way. Yes, I can see them jumping up, just as you say. Roger, fasten your eyes on the tree above, and tell me what that dark object is.”

A minute later, as they still kept pushing forward, Roger uttered a low cry.

“Well, after all, it’s an Indian brave up there. And he’s already shot a number of the brutes with his arrows; but I reckon his stock has given out. He tries to strike them as they jump at him, using his knife. And, Dick, I can see now that he isn’t a Mandan Indian at all, but more likely one of those Sioux who, under their sub-chief, Beaver Tail, did us such a good turn last fall, when we saved Jasper Williams from the French traders. But what can a Sioux warrior be doing here, in the land of his foes, the Mandans?”

“‘HE TRIES TO STRIKE THEM AS THEY JUMP AT HIM’”
