"What did you ask that for, Lub?"

X-Ray made this inquiry. He realized that the other must have something on his mind, or he would not have spoken as he did. And X-Ray was curious to know what its character might turn out to be.

"Oh, nothing much; only it strikes me that's a whopping big chimney, that's all," replied the other, a little confused.

"I see what you mean," said Phil; "you're thinking that even if we do close the door as we intend, if a thief wanted to get in here he could creep down such a wide-throated chimney? Well, I shouldn't be at all surprised if he could, providing he took the notion."

"I hate to think of being sound asleep, and not know a single thing about it," pursued Lub, "You know how I caught that darky stealing our chickens last winter? I set a trap for him, and gave him such a scare that he just crouched in a corner of the coop with all the hens cackling like mad, till father went out and got him by the scruff of the neck."

"Mebbe you'd like to set one of your fine traps here then, Lub," suggested Ethan.

"I think I could do it, if the rest of you didn't object," Lub pursued.

"Please yourself," said Phil.

"I'm off to bed right now," added X-Ray Tyson, "so you c'n have the whole blooming field to yourself. Be sure you don't get nabbed in your own contraption, Lub. Now, you may smile at my saying that, but it wouldn't be the first time a bitter got bitten."

Both Phil and Ethan began to stretch, and exhibited other positive signs of being ready to turn in. It would appear that none of the rest of them gave much thought to the possibility of their having unwelcome visitors during the night. Lub envied them their calm indifference; but he felt that he would not be doing his whole duty unless he carried out that idea of the trap.
