It seemed as if the walls would shatter and the roof come tumbling down at their prodigious hullabaloo. The bats raced to and fro. Scores of fishes pushed up their snouts round Nod's raft, and gazed with curious faces into the torchlight. The water was all astir with their disquietude. But in the midst of the song there sounded a shrill and hasty cry: "Down all!"

Only just in time had Ghibba seen their danger, and almost before the shrill echo had died away, and Thimble had cast himself flat, their raft was swirled under a huge rock, blossoming with quartz, that hung down almost to the surface of the water. Thimble's jacket was ripped collar to hem as he slid under, lying as close as he could. And the bobbing raft of baggage behind them was torn away in a twinkling, so that now all the food and torches the Mulgars had was what each carried for himself. They dared not stir nor lift their heads, for still the fretted roof arched close above the water. And so they drifted on and on, their torches luckily burnt low, until at length the cavern widened, the roof lifted, and they burst one by one into a great chamber of smooth water, its air filled strangely with a faint phosphorescence, so that every spar and jag of rock gleamed softly with coloured light as they paddled their course slowly through. In this great chamber they stayed awhile, for there was scarcely any current of water against its pillared sides. With their rafts clustering and moored together, they shared out equally what nuts, dry fruit, and unutterably mouldy cheese remained, and divided the torches equally between them, except that Ghibba, who led the way, had two for every one of the others.

These thin grey waters swarmed with fish, but all, it seemed, nearly blind, with scarcely visible eyes above their snouts. Some of the bigger fish, with clapping jaws, cast themselves in range or hunger against the rafts. And the Mulgars, seeing their teeth, took good heed to couch themselves close in the midst of their rafts. The longer they stayed, the thicker grew the concourse of fish drawn together by the noise and smell of the travellers, until the cavern echoed with their restless fins and a kind of supping whisper, as if the fish had speech. So the Mulgars pushed off again, laying about them with their poles to scare the bolder monsters off as they gilded softly into the sluggish current, until the channel narrowed again, and their speed freshened.

On and on they drifted. On and on the shimmering walls floated past them, now near, now distant. They lost all time. Some said night must be gone; some said nay, night must have come again; and to some it seemed like an evil dream, this drifting, without beginning or end. When sleep began to hang heavily on Thumb's eyelids, he bade Nod lie down and take his fill of it first, while he himself kept watch. Nod very gladly lay down as comfortably as he could on the rough and narrow raft, and Thumb for safety tied him close with a strand of Cullum. He dreamed a hundred dreams, rocked softly on the sliding raft, all of burning sunshine, or wild white moonlight, or of icy and dazzling Witzaweelwūlla; but the Water-midden's beauty haunted all.

He woke into almost pitch-black gloom, and, starting up, could count only four torches staining the unrippling water with their flare. And, being very thirsty, he stooped over with hollowed hand, as if to drink.

"No, no," said Thumb drowsily; "not drink, Nod. Sleepy water—sleepy water. Moona-mulgars there, drunk and drunk; thirstier and thirstier, torches out—all dead asleep—all dead asleep."

"But my tongue's crackling dry, Thumb. Drink I must, Thumb."

"Nutshells," said Thumb—"suck nutshells, suck them."

Nod took out the last few nuts he had. And in the faint glowing of the distant torches he could see Thumb's great broad-nosed face turned hungrily towards them.

"How many nuts left have you, my brother?" Nod said.
