"By Jove!" he observed.

Harvey went more deeply into the question.

"What makes you think they meet down here?" he asked.

"I saw some fellows cutting out of here last night. And you say ye've
seen them here, too. I don't see what object they could have down here
if they weren't the League holding a meeting. I don't see what else a
chap would be after."

"He might be keeping ferrets," hazarded Renford.

"The whole school doesn't keep ferrets," said O'Hara. "You're unique in
that way. No, it must be the League, an' I mean to wait here till they
come."

"Not all night?" asked Harvey. He had a great respect for O'Hara, whose
reputation in the school for out-of-the-way doings was considerable. In
the bright lexicon of O'Hara he believed there to be no such word as
"impossible."

"No," said O'Hara, "but till lock-up. You two had better cut now."

"Yes, I think we'd better," said Harvey.

"And don't ye breathe a word about this to a soul"--a warning which
extracted fervent promises of silence from both youths.
