“But she’s been dreadfully frightened, Susan,” cried Nan, sympathetically.

“She saw a ghost, Susan,” whispered Bess, perhaps a little wickedly.

Susan rolled her eyes. “Go ’long, chile! Wot ghos’?”

“The boathouse ghost, I declare!” said Bess, with decision. “Wasn’t it, Nan? All black—and small—and it squealed. Didn’t it, Nan?”

“It was a boy,” said her chum. “And he ran down cellar. Somebody ought to look into it.”

“Into the cellar?” asked Bess, with a giggle, as Susan “shooed” them out of the matron’s room and shut the door at their backs.

“Yes. Just that,” said Nan, decidedly.

“Where do you suppose that boy went—if it was a boy?”

“I know,” Nan said, hesitating at the top of the stairs.

“You know?” cried Bess.
