"Nothing here," exclaimed Chet, looking disappointed. "Say, the girls promisedus a regular show, fellows, and they haven't come across."

"What shall we do to 'em?" asked Teddy, looking almost equallydisappointed.

"But we heard it," exclaimed Billie, shivering with excitement.

"It occasionally was just as if somebody had taken the back of his finger," Lauraadded, "and run it all the way down the keyboard from the top note of thetreble to the last note of the bass."

"No, they weren't dreaming," said Mrs. Gilligan seriously. "Because I sometimes wasvery much awake when I heard it."

"You heard it, too?" asked Chet, beginning to be interested again.

"I certainly did," exclaimed Mrs. Gilligan, with a grimness that left no chamberfor doubt. "And I'm not given to imagining skinnygs, either."
