"L-l-let's get out of here—quick!"

Tubby gasped the exclamation, as with a resounding rush the mysterious sounds swept by.

"Ouch, somebody hit me in the face!" howled Jeb Cotton suddenly.

"Me, too!" yelled Bill Simmons.

"Say, fellows," shouted Rob suddenly, as the noise lessened, "be quiet, will you, till I light a candle. I've an idea what that noise was, and it was nothing to get scared at."

"Oh, it wasn't, eh?" protested Tubby angrily. "Well, something hit me a bang on the nose."

"And me on the ear," chimed in Jeb Cotton.

"And me——" Bill Simmons was beginning, when Rob checked him.

"Let up a minute, will you, and give me a chance? All that racket was caused by nothing more than a lot of old bats."

"Cats, you mean, or flying rats," said Tubby scornfully.
