They urged the horses to a canter and thundered along the dusky road in fine style. But
almost at once it began going downhill. They would have thought Golg had sent them the
wrong way if they had not seen, on the other side of the valley, the lamps going on and
upwards as far as the eye could reach. But at the bottom of the valley the lamps shone on
moving water.
"Haste," cried the Prince. They galloped down the slope. It would have been nasty
enough at the bottom even five minutes later for the tide was running up the valley like a
mill-race, and if it had come to swimming, the horses could hardly have won over. But it
was still only a foot or two deep, and though it swished terribly round the horses' legs,
they reached the far side in safety.
Then began the slow, weary march uphill with nothing ahead to look at but the pale
lamps which went up and up as far as the eye could reach. When they looked back they
could see the water spreading. All the hills of Underland were now islands, and it was
only on those islands that the lamps remained. Every moment some distant light
vanished. Soon there would be total darkness everywhere except on the road they were
following; and even on the lower part of it behind them, though no lamps had yet gone
out, the lamplight shone on water.
Although they had good reason for hurrying, the horses could not go on for ever without
a rest. They halted: and in silence they could hear the lapping of water.
"I wonder is what's his name - Father Time - flooded out now," said Jill. "And all those
queer sleeping animals."
"I don't think we're as high as that," said Eustace. "Don't you remember how we had to go
downhill to reach the sunless sea? I shouldn't think the water has reached Father Time's
cave yet."
"That's as may be," said Puddleglum. "I'm more interested in the lamps on this road.
Look a bit sickly, don't they?"
"They always did," said Jill.
"Aye," said Puddleglum. "But they're greener now."
"You don't mean to say you think they're going out?" cried Eustace.
"Well, however they work, you can't expect them to last for ever, you know," replied the
Marsh-wiggle. "But don't let your spirits down, Scrubb. I've got my eye on the water too,
and I don't think it's rising so fast as it did."
"Small comfort, friend," said the Prince. "If we cannot find our way out. I cry you mercy,
all. I am to blame for my pride and fantasy which delayed us by the mouth of the land of
Bism. Now, let us ride on."
