Suddenly he cried:

"How do you know all this? How do you know what is or is not in the letter I gave you?"

Sweetwater, with a shrug that in its quiet significance seemed to make him at once the equal of his interrogator, quietly pressed the quivering limb under his hand and calmly replied:

"I know because I have read it. Before putting my head in the lion's mouth, I make it a point to count his teeth," and lifting his hand, he drew back, leaving the captain reeling.

"What is your name? Who are you?" shouted out Wattles as Sweetwater was drawing off.

It was the third time he had been asked that question within twenty-four hours, but not before with this telling emphasis. "Who are you, I say, and what can you do to me—?"

"I am—But that is an insignificant detail unworthy of your curiosity.
As to what I can do, wait and see. But first burn that letter."

And turning his back he fled out of the building, followed by oaths which, if not loud, were certainly deep and very far-reaching.

It was the first time Captain Wattles had met his match in audacity.
