For one nasty moment, Harry thought that Hagrid was going to lead them into the forest; Harry had had enough unpleasant experiences in there to last him a lifetime. However, Hagrid strolled off around the edge of the trees, and five minutes later, they found themselves outside a kind of paddock. There was nothing in there.

"Everyone gather 'round the fence here!" he called. "That's it -- make sure yeh can see -- now, firs' thing yeh'll want ter do is open yer books --"

"How?" said the cold, drawling voice of Draco Malfoy. "Eh?" said Hagrid.

"How do we open our books?" Malfoy repeated. He took out his copy of The Monster Book of Monsters, which he had bound shut with a length of rope. Other people took theirs out too; some, like Harry, had belted their book shut; others had crammed them inside tight bags or clamped them together with binder clips.

"Hasn' -- hasn' anyone bin able ter open their books?" said Hagrid, looking crestfallen.

The class all shook their heads.

"Yeh've got ter stroke 'em," said Hagrid, as though this was the most obvious thing in the world. "Look --"

He took Hermione's copy and ripped off the Spellotape that bound it. The book tried to bite, but Hagrid ran a giant forefinger down its spine, and the book shivered, and then fell open and lay quiet in his hand.

"Oh, how silly we've all been!" Malfoy sneered. "We should have stroked them! why didn't we guess!"

"I -- I thought they were funny," Hagrid said uncertainly to Hermione.

"Oh, tremendously funny!" said Malfoy. "Really witty, giving us books that try and rip our hands off!"

"Well, I see you have both hands, so I frankly don't see a damn problem with the books," said Amelia as she stroked her book.
