“Hark!” said Mr. Lewis suddenly. “What’s that noise?”
“I didn’t hear anything,” said Bob, straining his ears to listen.

“Was that a wild animal?” demanded Joe, who had almost turned pale.
“I’ve never heard any wild animal that could make that kind of a noise,” returned Mr. Holton, and Joe’s father shook his head.
“It didn’t sound like people, either,” came from Joe. “Ugh! Gives me the shivers. Maybe it was a ghost.”
Mr. Lewis tried to laugh.
