The_Complete_Chronicles_of_Narnia_(volumes_1-7,_in_order_of_publication)

As they went on, the Rush began to fall more and more steeply. Their journey became
more and more of a climb and less and less of a walk - in places even a dangerous climb
over slippery rock with a nasty drop into dark chasms, and the river roaring angrily at the
bottom.
You may be sure they watched the cliffs on their left eagerly for any sign of a break or
any place where they could climb them; but those cliffs remained cruel. It was
maddening, because everyone knew that if once they were out of the gorge on that side,
they would have only a smooth slope and a fairly short walk to Caspian's headquarters.
The boys and the Dwarf were now in favour of lighting a fire and cooking their bearmeat.
Susan didn't want this; she only wanted, as she said, "to get on and finish it and get
out of these beastly woods". Lucy was far too tired and miserable to have any opinion
about anything. But as there was no dry wood to be had, it mattered very little what
anyone thought. The boys began to wonder if raw meat was really as nasty as they had
always been told. Trumpkin assured them it was.
Of course, if the children had attempted a journey like this a few days ago in England,
they would have been knocked up. I think I have explained before how Narnia was
altering them. Even Lucy was by now, so to speak, only one-third of a little girl going to
boarding school for the first time, and two-thirds of Queen Lucy of Narnia.
"At last!" said Susan.
"Oh, hurray!" said Peter.
The river gorge had just made a bend and the whole view spread out beneath them. They
could see open country stretching before them to the horizon and, between it and them,
the broad silver ribbon of the Great River. They could see the specially broad and shallow
place which had once been the Fords of Beruna but was now spanned by a long, manyarched
bridge. There was a little town at the far end of it.
"By Jove," said Edmund. "We fought the Battle of Beruna just where that town is!"
This cheered the boys more than anything. You can't help feeling stronger when you look
at a place where you won a glorious victory not to mention a kingdom, hundreds of years
ago. Peter and Edmund were soon so busy talking about the battle that they forgot their
sore feet and the heavy drag of their mail shirts on their shoulders. The Dwarf was
interested too.
They were all getting on at a quicker pace now. The going became easier. Though there
were still sheer cliffs on their left, the ground was becoming lower on their right. Soon it
was no longer a gorge at all, only a valley. There were no more waterfalls and presently
they were in fairly thick woods again.
