"AND so," said Trumpkin (for, as you have realized, it was he who had been telling all
this story to the four children, sitting on the grass in the ruined hall of Cair Paravel) -
"and so I put a crust or two in my pocket, left behind all weapons but my dagger, and
took to the woods in the grey of the morning. I'd been plugging away for many hours
when there came a sound that I'd never heard the like of in my born days. Eh, I won't
forget that. The whole air was full of it, loud as thunder but far longer, cool and sweet as
music over water, but strong enough to shake the woods. And I said to myself, `If that's
not the Horn, call me a rabbit.' And a moment later I wondered why he hadn't blown it
sooner-"
"What time was it?" asked Edmund.
"Between nine and ten of the clock," said Trumpkin.
"Just when we were at the railway station!" said all the children, and looked at one
another with shining eyes.
"Please go on," said Lucy to the Dwarf.
"Well, as I was saying, I wondered, but I went on as hard as I could pelt. I kept on all
night - and then, when it was half light this morning, as if I'd no more sense than a Giant,
I risked a short cut across open country to cut off a big loop of the river, and was caught.
Not by the army, but by a pompous old fool who has charge of a little castle which is
Miraz's last stronghold towards the coast. I needn't tell you they got no true tale out of
me, but I was a Dwarf and that was enough. But, lobsters and lollipops! it is a good thing
the seneschal was a pompous fool. Anyone else would have run me through there and
then. But nothing would do for him short of a grand execution: sending me down `to the
ghosts in the full ceremonial way. And then this young lady", (he nodded at Susan) "does
her bit of archery and it was pretty shooting, let me tell you - and here we are. And
without my armour, for of course they took that." He knocked out and refilled his pipe.
"Great Scott!" said Peter. "So it was the horn - your own horn, Su - that dragged us all off
that seat on the platform yesterday morning! I can hardly believe it; yet it all fits in."
"I don't know why you shouldn't believe it," said Lucy, "if you believe in magic at all.
Aren't there lots of stories about magic forcing people out of one place - out of one world
- into another? I mean, when a magician in The Arabian Nights calls up a Jinn, it has to
come. We had to come, just like that."
"Yes," said Peter, "I suppose what makes it feel so queer is that in the stories it's always
someone in our world who does the calling. One doesn't really think about where the
Jinn's coming from."
