“I’m sure of it!” gasped Joe, from inside. Then there was another gurgle and Joe said no more because he had received a mouthful of soot.

“Soot,” said Chet.

They waited. Then they heard a muffled cry of dismay.

“What’s the matter?” they shouted.

“I’m stuck! I got up here, but now I can’t get back.” Joe evidently gave a violent lunge for freedom, because an unusually heavy shower of soot followed.

“Come on, fellows! Don’t stand down there doing nothing!” he clamored. “Get me out of this before I smother!”
