“But—but what is it?” asked Allan, bewildered.

“Don’t know; nobody knows. There’s the bell and there’s the rope; no one’s pulling it; must be spooks! Isn’t it jolly?” And Hal leaped with delight and thumped Allan on the back.

“But why does the bell ring?” he asked, following the general example and staring upward at the tower.

“That’s it! Why does it? Some say it’s the wind, but that’s poppycock, you know. What I think is that some one’s got a rope hitched to the bell and is pulling it from the back of the building somewhere; that’s what I think.”

“But haven’t they been around there to see?”

“Yes, but they’re so excited and fussed they wouldn’t know a rope if they fell over it. Some one’s having a lark, you can bet on that. Isn’t it a picnic? Just hear the old bell! Wow! Listen to that!”

Allan put his mouth to Hal’s ear and whispered a single word. Hal started, shot a glance at Pete’s window and Pete himself, and burst into a gale of laughter.

“D-d-do you think so?” he gasped. “But—how could he? Look, there he is at the window. O Pete!”

“Hush up!” whispered Allan. “They’ll get onto it. Look, they’ve got a ladder! They’ll find out what’s up now, all right, because the rope will be hanging. We ought to warn Pete; come on!”

They wormed their way through the crowd, exchanging shouts of salutation with acquaintances as they went, until they were under Pete’s window. There they found Tommy, note-book in hand, looking very important and excited.
