And Plunger chuckled so that it seemed as though he would never be able to stop himself. Just to keep him company, Harry chuckled too.

"Splendid little joke, isn't it, Harry?"

"Splendid."

"I told you what fun you'd have when you got to Garside. Better than Gaffer Quelch's, eh? Things were awfully slow there, weren't they, Harry?"

"Awfully."

But, so far as fun was concerned, Harry couldn't see that he had had very much of it, except at his own expense. Plunger had, in fact, made him his butt, and now he wished to score off Baldry through his instrumentality.

"I didn't quite understand you, Freddy," said Harry presently, as Plunger went on chuckling. "Who do you say was to be up in the tree at the back of the Forum and pull the string?"

"You, Harry. I'm giving you the post of honour, because you deserve it. Baldry has poked fun at you a lot. Now it's your turn, old fellow."

"It's very kind of you, Freddy—it really is. I don't know how to be grateful enough. I'm to be in the tree, you say: but where will you be?"

"Oh, I'll do the whistling."
