"If the old trap did go up in smoke I guess nobody would care much," muttered Lil Artha, as he pressed his face still further into the opening, after Elmer released his fire ball.

The burning paper seemed to alight upon the damp earthen floor of the cellar. Immediately both boys tried to secure a mental photograph of all there was below them.

"It's only a log!" cried Lil Artha, in a relieved tone of voice, and at the same time betraying more or less disappointment, for perhaps he had made up his mind that they were to be treated to some species of horror.

"You're right," added Elmer, "that's what it is—an old log that has lain there, goodness only knows how long. Nat doesn't seem to have slipped down into the cellar, then, does he?"

"Not that you could notice," replied Lil Artha, and then he added: "but Elmer, didn't you notice something jump when that paper first went down?"

"Well, yes, I did, for a fact, Arthur."

"Any idea what it could be?" persisted the other.

"I hope you're not thinking of that ghost we've heard so much about?" said Elmer.

"Now, that's hardly fair, Elmer; you know I don't take any stock in fairy tales or hobgoblin yarns. But something sure moved."

"A big rat I guess, perhaps a muskrat from the pond above. They sometimes find a burrow leads them to some old, unused cellar."
