Mac poured it down without seeming to bother about tasting it.

They sat quite still after that, till the Colonel said meditatively:

"You and I had a little account to settle, didn't we?"

"I'm ready."

But neither moved for several moments.

"See here, Mac: you haven't been ill or anything like that, have you?"

"No." There was no uncertain note in the answer; if anything, there was in it more than the usual toneless decision. Mac's voice was machine-made—as innocent of modulation as a buzz-saw, and with the same uncompromising finality as the shooting of a bolt. "I'm ready to stand up against any man."

"Good!" interrupted the Colonel. "Glad o' that, for I'm just longing to see you stand up—"

Mac was on his feet in a flash.

"You had only to say so, if you wanted to see me stand up against any man alive. And when I sit down again it's my opinion one of us two won't be good-lookin' any more."
