"But why should Harry take up with him?" Pence's tone was savage.

"You should know, if Kirby is so thick with the aborigine. Look as though they might be brothers in the same boat, belong to the same lodge, as it were. Kirby may be heap big Injun, too," Kingdon laughed lightly.

"Oh, he's an Indian all right," gloomily agreed Horace Pence, "but not Joe Bootleg's kind. I never knew Harry to do a really mean thing. He's too white a fellow, I believe, to lend himself to a job like that."
