He thought he was walking straight, but really he was turning first this way and then that, and then the other way among the avenues of silver pillars which all looked just alike.
He was getting very tired, and he had been walking a long time, before he came to anything that was not silver pillars and velvet black under invisible roofs, and floor paved with dominoes laid very close together.
'Oh, I am glad!' he said at last, when he saw the pavement narrow to a single line of dominoes just like the path he had come in by.

There was an arch too, like the arch by which he had come in.

And then he perceived in a shock of miserable surprise that it was, in fact, the same arch and the same domino path.

He had come back, after all that walking, to the point from which he had started.

It was most mortifying.
So silly! Philip sat down on the edge of the domino path to rest and think.
'Suppose I just walk out and don't believe in magic any more ?' he said to himself.
