'It is rather decent, isn't it?' said Guy dispa.s.sionately.

Sir Christopher raised the pot, carried it in, and the door was shut.

The children found themselves in a small square hall. A winding staircase of iron corkscrewed upwards in one corner. The hall was lighted only by two candles.

The old gentleman led the way through a door on the right into a round room with white walls.

'We're inside the tower now,' said Guy.

'Yes,' said their host, 'this is part of the tower.'

He hastily lighted a big lamp, and then a deep 'Oh!' broke from the children. For the walls were not white, they were all of mother-of-pearl, and here and there all over the walls round pearls shone with a starry, milky radiance.

'How radishing!' said Mabel in a whisper. 'I always said he wasn't a miser. He's a magician.'

'What a lovely, lovely room!' sighed Phyllis.

'What's it made of?' asked Guy downrightly.

'Oyster-sh.e.l.ls,' said Sir Christopher, 'and pearl beads.'

And it was.

'Oh!' said Mabel gaily, 'then that's what you go prowling about in dirty gutters for?'

'Don't be rude, Mab dear!' whispered Phyllis.

But the old gentleman did not seem to mind. He just said, 'Yes, that's it,' in an absent sort of way. He seemed to be thinking about something else. Then he said, 'The Christmas-tree.'

The children had forgotten all about the Christmas-tree.

When its seventy-two candles were lighted the pearly room shone and glimmered like a fairy palace in a dream.

'It's many a year since my little girl had such a Christmas-tree,' he said. 'I don't know how to thank you.'

'Seeing your pearly halls is worth all the time and money,' said Mabel heartily.

And Phyllis added in polite haste:

'And you being pleased.'

'Would you like to see the black marble hall?' asked Sir Christopher.

And, of course, they said, 'Yes, awfully.'

So he led them into the room on the other side of the hall, and lighted a lamp. And the room was like a room of black marble, carved into little round k.n.o.bs.

'How lovely!' said Phyllis.

'It's not lovely like the other,' said Mabel; 'but it's more serious, like when the organ plays in church.'

'Why,' said Guy suddenly, 'it's winkle-sh.e.l.ls!'

And it was. Hundreds and thousands of winkle-sh.e.l.ls sorted into sizes and stuck on the walls in patterns, and then, it seemed, polished or varnished.

'Come,' said Sir Christopher, 'I'll show you the red-room.'

As they turned to go a tall, white figure by the door seemed to come suddenly into the lamplight. It was covered with a sheet.

'Oh!' said all three, starting back, 'what's that?'

'That's my little girl,' he said.

'Is she trying to frighten us? Is she playing ghosts?' asked Guy.

'No,' he said; 'she never plays at ghosts. It isn't her really. That's only my fun. It's a statue really.'

'Aren't statues very dear?' asked Guy.

'Very,' said Sir Christopher--'very, very dear.'

He led the way up the winding iron stair and showed them the red-room.

Its walls were covered with bits of red lobster-sh.e.l.ls, overlapping like a fish's scales or the plates of armour.

'How resplendid!' said Mabel; 'I believe you're a mighty magician.'

'No,' he said; 'at least--no, not exactly. There's only one more room.'

The other room was a bedroom, quite dull and plain, with whitewashed walls and painted deal furniture.

'I like the pearly halls best,' said Mabel: 'they're more eloquent;' and they all went down to the room where the seventy-two candles of the Christmas-tree were burning steadily and brightly, though there was no one to see them.

'Won't you call your little girl?' said Phyllis. 'The candles won't last so very long; they're the cheap kind.'

Sir Christopher twisted his fingers together.

'It's no use calling her,'he said. 'Would you mind--do you mind leaving the tree for to-night? You could fetch it to-morrow. And you won't tell anyone about the inside of my house, will you? They'd only laugh at it.'

'I don't see how they could,' said Mabel indignantly; 'it's the beautifullest, gorgerest house that ever was.'

'But we won't tell anyone,' said Guy. 'And we'll come again to-morrow--about the same time.'

Sir Christopher said, 'Yes, please.'

And they all shook hands with him and came away, leaving the Christmas-tree, with all its seventy-two candles, still making the pearly room a dream of fairy beauty.

They ran all the way home, because it was rather late, and they did not want the servants to fetch them from the parish schoolroom, where they had not spent the evening. It would have been very difficult to explain exactly where and how they _had_ spent it, and the fact that they had promised not to say anything about it would have added considerably to the difficulty.

When they had been let in, and had taken off their hats and jackets and got their breaths, they looked at each other.
