"We can trust every man here," declared Audubon quietly but impressively. "The grounds of this house are guarded by armed men, Norton——"

"But how do you know they can all be trusted?" demanded the Louisianian keenly.

"Because, sir," spoke up Ayres, "Mr. Audubon and I enlisted them personally. We went up-river and carefully selected only those who had lost brothers or sons or fathers with the boats which have vanished down the river. Every man of us here has sustained heavy losses in property from the same cause. In short, sir, we have raised a company of Regulators, with which to exterminate this pestilent Blacknose gang."

Norton whistled to himself, eyeing the energetic little schoolmaster in some admiration as the whole thing broke over his mind. So then, they were fighting secrecy with secrecy, organization with organization!

Now he understood a good deal which had mystified him—the words of Kitty Grigg, the odd silence of his boatmen, the manner in which the two bellicose rivermen had been disposed of. Ayres had been swift and clever, also; by enlisting only the relatives of the men who had disappeared with their boats, during the past two years, all possibility of treachery was removed and the "Regulators" were certain to be animated by a live hatred of Duval—but did they know of Duval yet? Norton flung a quick glance around and found all waiting for him to speak. "How many here know who Blacknose is, Audubon?"

The words were like a shock; Norton needed no other answer to his question than the startled questioning look which ran over the faces in a flash.

"Only Ayres," returned the bird-lover, gravely. "It is a thing we cannot prove definitely, and it would be much better to destroy the whole gang at one blow. We will lay our suspicions before these friends of ours to-night, and take counsel."

While Audubon was speaking, a white-haired negro flung back the curtains which shut off the dining-room, and now announced dinner. Mr. Tarascon rose.

"Then—you have ascertained something definite, Mr. Norton?"

"Yes. I may say that we have ascertained everything."
