I listened and at first heard nothing, and was just about to say that it must be the screech-owl come closer, when from a corner of the house there came a distant and sharp crackle. I heard Alf scuffle to his feet. "We are in for it!"

It was true, for now we could see the light glaring on the bushes and a moment later a spear of light shot inward, revealing my friend standing there with his hands buried deep in his pockets. "Those old logs are as dry as a powder horn," he carelessly remarked. "Won't take long to burn the thing down."

"But what are we going to do?" I cried. And now the room was aglow, and shadows were dancing on the wall.

"I was just thinking," said he, looking about. "They'll begin shooting in here as soon as that end is burned out. Wish I had seen that rascal when he slipped up here to kindle this fire. Helloa, it's spread to the roof."

I strove to show him that I could be as calm and as careless as he, but now I was startled, and excitedly exclaimed: "We shall be burned up like rats in a barn!"

"Oh, I reckon not. Here, let's pull up a plank out of the floor and crawl under and if we can get into the bushes we'll be all right. Here's a crack. But I can't move it," he added, after straining at the board. "See if you can get your fingers through here."

I dropped upon my knees and thrust my fingers through the crack. The fire had now gained such headway that the air was hot and a glare danced on the wall where the shadow had crept; and we heard the Aimes boys yell in the woods a short distance off. With all my strength I pulled at the board; I got off my knees and braced myself, and with a quick jerk the board came up with a loud rip and I fell backward on the floor.

"Go ahead," said Alf, quietly standing there, with his gun under his arm. "Get down through and work your way toward the other end."

"You go first, Alf."

"I'm in no hurry. But may be I know of an opening where the sheep come under in winter. Follow me, then."
