'The top of that's just the exactly same size as the carpet,' said
Jane. '_I_ think it would be good to go to the top of that, because
then none of the Abby-what's-its-names--I mean natives--would be
able to take the carpet away even if they wanted to. And some of
us could go out and get things to eat--buy them honestly, I mean,
not take them out of larder windows.'

'I think it would be better if we went--' Anthea was beginning; but
Jane suddenly clenched her hands.

'I don't see why I should never do anything I want, just because
I'm the youngest. I wish the carpet would fit itself in at the top
of that tower--so there!'

The carpet made a disconcerting bound, and next moment it was
hovering above the square top of the tower. Then slowly and
carefully it began to sink under them. It was like a lift going
down with you at the Army and Navy Stores.

'I don't think we ought to wish things without all agreeing to them
first,' said Robert, huffishly. 'Hullo! What on earth?'

For unexpectedly and greyly something was coming up all round the
four sides of the carpet. It was as if a wall were being built by
magic quickness. It was a foot high--it was two feet high--three,
four, five. It was shutting out the light--more and more.

Anthea looked up at the sky and the walls that now rose six feet
above them.
