There was a flash of fire and the phoenix had gone.
Dumbledore now swooped down upon one of the fragile silver instruments whose function Harry had never known, carried it over to his desk, sat down facing them again and tapped it gently with the tip of his wand.
The instrument tinkled into life at once with rhythmic clinking noises. Tiny puffs of pale green smoke issued from the minuscule silver tube at the top. Dumbledore watched the smoke closely, his brow furrowed. After a few seconds, the tiny puffs became a steady stream of smoke that thickened and coiled in the air… a serpent’s head grew out of the end of it, opening its mouth wide. Harry wondered whether the instrument was confirming his story: he looked eagerly at Dumbledore for a sign that he was right, but Dumbledore did not look up.
“Naturally, naturally,” murmured Dumbledore apparently to himself, still observing the stream of smoke without the slightest sign of surprise. “But in essence divided?”
Harry could make neither head nor tail of this question. The smoke serpent, however, split itself instantly into two snakes, both coiling and undulating in the dark air. With a look of grim satisfaction, Dumbledore gave the instrument another gentle tap with his wand: the clinking noise slowed and died and the smoke serpents grew faint, became a formless haze and vanished.
Dumbledore replaced the instrument on its spindly little table. Harry saw many of the old headmasters in the portraits follow him with their eyes, then, realising that Harry was watching them, hastily pretend to be sleeping again. Harry wanted to ask what the strange silver instrument was for, but before he could do so, there was a shout from the top of the wall to their right; the wizard called Everard had reappeared in his portrait, panting slightly.
“Dumbledore!”
“What news?” said Dumbledore at once.
“I yelled until someone came running,” said the wizard, who was mopping his brow on the curtain behind him, “said I’d heard something moving downstairs—they weren’t sure whether to believe me but went down to check—you know there are no portraits down there to watch from. Anyway, they carried him up a few minutes later. He doesn’t look good, he’s covered in blood, I ran along to Elfrida Cragg’s portrait to get a good view as they left—”
“Good,” said Dumbledore as Ron made a convulsive movement. “I take it Dilys will have seen him arrive, then—”
And moments later, the silver-ringleted witch had reappeared in her picture, too; she sank, coughing, into her armchair and said, “Yes, they’ve taken him to St. Mungo’s, Dumbledore… they carried him past my portrait… he looks bad…”
“Thank you,” said Dumbledore. He looked round at Professor McGonagall.
“Minerva, I need you to go and wake the other Weasley children.”
