There was a stove in the main cabin with a stovepipe going straight up through the roof like a smoke stack and there was a damper in it right near the stove.
"Get a handbook or a pocket code," somebody said, "so he'll have the signs right near him." "He doesn't need any signs," Pee-wee shouted, disgusted like.
Well, this is the way Wig did it, and after he got started, most of us went up on the roof to see if we could read it.

But that's mighty hard to do when you're right underneath it.
By the time the fellows came upstairs with the damp excelsior (that's what they call the smudge) Wig had a good fire started in the stove.
"Lay that stuff down here," he said; then he said to me, "What do you want to say ?" "Just say I'm safe, Wig," I told him.

"Say for them not to pay any attention to what they hear." I only waited long enough for him to get started, just so as to see how he did it, then I went up on the roof and watched the long black smoke column.

Cracky, I was glad it was moonlight, that's one sure thing.
As soon as he had a good fire started he stuffed some of the damp excelsior in and shut the door, and told Artie Van Arlen (he's their patrol leader) to hold a rag over the crack in the door, because the black smoke was pouring out that way, especially because the damper in the pipe was shut.
I didn't stay there long, because the smoke was too thick for me and when I saw Artie bind a wet rag over Wig's eyes and mouth, I knew then it was going to be mighty bad in that little cabin.
"Have another ready," I heard him say; "better have three or four of them." Then he put his hand on the damper in the pipe and turned it and then the smoke in the cabin wasn't so bad.

He just turned it around quick and kept turning it around and that let little puffs of smoke through, and I heard the fellows up on the roof shouting, "Hurrah!" so I knew it was working all right.
