If she was such an old lady, she could hardly be supposed to have set out alone and on foot when all the house was asleep.

Still, away she must have gone, for, of course, if she was so powerful, she would always be about the princess to take care of her.
But as Curdie grew older, he doubted more and more whether Irene had not been talking of some dream she had taken for reality: he had heard it said that children could not always distinguish betwixt dreams and actual events.

At the same time there was his mother's testimony: what was he to do with that?
His mother, through whom he had learned everything, could hardly be imagined by her own dutiful son to have mistaken a dream for a fact of the waking world.
So he rather shrank from thinking about it, and the less he thought about it, the less he was inclined to believe it when he did think about it, and therefore, of course, the less inclined to talk about it to his father and mother; for although his father was one of those men who for one word they say think twenty thoughts, Curdie was well assured that he would rather doubt his own eyes than his wife's testimony.
There were no others to whom he could have talked about it.

The miners were a mingled company--some good, some not so good, some rather bad--none of them so bad or so good as they might have been; Curdie liked most of them, and was a favourite with all; but they knew very little about the upper world, and what might or might not take place there.

They knew silver from copper ore; they understood the underground ways of things, and they could look very wise with their lanterns in their hands searching after this or that sign of ore, or for some mark to guide their way in the hollows of the earth; but as to great-great-grandmothers, they would have mocked Curdie all the rest of his life for the absurdity of not being absolutely certain that the solemn belief of his father and mother was nothing but ridiculous nonsense.
