"But where?"

"Oh, nowheres in particular. Come on."

Diamond obeyed. The wind had now fallen considerably. They wandered
on and on, turning in this direction and that, without any reason
for one way more than another, until they had got out of the thick
of the houses into a waste kind of place. By this time they were both
very tired. Diamond felt a good deal inclined to cry, and thought
he had been very silly to get down from the back of North Wind;
not that he would have minded it if he had done the girl any good;
but he thought he had been of no use to her. He was mistaken there,
for she was far happier for having Diamond with her than if she had
been wandering about alone. She did not seem so tired as he was.

"Do let us rest a bit," said Diamond.

"Let's see," she answered. "There's something like a railway there.
Perhaps there's an open arch."

They went towards it and found one, and, better still, there was
an empty barrel lying under the arch.

"Hallo! here we are!" said the girl. "A barrel's the jolliest
bed going--on the tramp, I mean. We'll have forty winks, and then
go on again."

She crept in, and Diamond crept in beside her. They put their arms
round each other, and when he began to grow warm, Diamond's courage
began to come back.
