"Well, let's try if he's got any patriotism about him. Give him one stanza of the other song. If that doesn't make him look out, then we'd better put our horns away, and quit singing. We're dead failures as a drawing card, seems to me."

"You were right," observed Felix, a few minutes later, when, after they had done their level best rolling out the chorus, "And the Star Spangled Banner in triumph shall wave, o'er the land of the free and the home of the brave," not a single sign of an encore did they receive.

"He don't seem to mind it in the least," remarked Tom, grimly. "Perhaps now the old fellow may be stone deaf. I should think he must be, to stand for all that stuff, and never whimper once."

"But that couldn't be," declared Felix, "because he must have heard us talking that other time, when you saw him peeking over at us. I'm not so sure as you are that he's in just now."

"Well, here goes to prove it," said Tom, as he made a move as though intending to leave his tree; but when Felix also started to vacate, the other called out: "No, I want you to stay just where you are, and keep tabs on the opening. If you see the first sign of anything moving, you want to give me the tip right away, so I can run back to my tree."

"But what are you going to do?" asked Felix anxiously, for if there was anything dangerous to be accomplished, he did not see why Tom should not let him share in the enterprise.

"Just wait and see," was all the satisfaction he received. "And don't forget you gave me your solemn word to obey. I'm the captain of the ship just now, and the crew has got to do what the skipper says."

"But if you're going to take chances, I'd like to be along, Tom."

"Only one of us can do the little job; the other's business is to stay there, on guard, and give the alarm if anything shows up. And I've detailed you for that part of the programme, Felix."

So, unwilling though he was, the other had to sit there, rifle in hand, and try to figure out just what Tom meant to do, in order to bring the inmate of the den to his front door, in case he was at home.
