That evening he buried the core of the Apple in the back garden.
Next morning when the Doctor made his usual visit, Digory leaned over the banisters to listen. He heard the Doctor come out with Aunt Letty and say:
“Miss Ketterley, this is the most extraordinary case I have known in my whole medical career. It is—it is like a miracle. I wouldn't tell the little boy anything at present; we don't want to raise any false hopes. But in my opinion—” then his voice became too low to hear.
That afternoon he went down the garden and whistled their agreed secret signal for Polly (she hadn't been able to get back the day before).
“What luck?” said Polly, looking over the wall. “I mean, about your Mother?”
“I think—I think it is going to be alright,” said Digory. “But if you don't mind I'd really rather not talk about it yet. What about the rings?”
“I've got them all,” said Polly. “Look, it's alright, I'm wearing gloves. Let's bury them.”
“Yes, let's. I've marked the place where I buried the core of the Apple yesterday.”
Then Polly came over the wall and they went together to the place. But, as it turned out, Digory need not have marked the place. Something was already coming up. It was not growing so that you could see it grow as the new trees had done in Narnia; but it was already well above ground. They got a trowel and buried all the magic rings, including their own ones, in a circle round it.
About a week after this it was quite certain that Digory's Mother was getting better. About a fortnight later she was able to sit out in the garden. And a month later that whole house had become a different place. Aunt Letty did everything that Mother liked; windows were opened, frowsy curtains were drawn back to brighten up the rooms, there were new flowers everywhere, and nicer things to eat, and the old piano was tuned and Mother took up her singing again, and had such games with Digory and Polly that Aunt Letty would say “I declare, Mabel, you're the biggest baby of the three.”
When things go wrong, you'll find they usually go on getting worse for some time; but when things once start going right they often go on getting better and better. After about six weeks of this lovely life there came a long letter from Father in India, which had wonderful news in it. Old Great-Uncle Kirke had died and this meant, apparently, that Father was now very rich. He was going to retire and come home from India forever and ever. And the great big house in the country, which Digory had heard of all his life and never seen would now be their home; the big house with the suits of armour, the stables, the kennels, the river, the park, the hot-houses, the vineries, the woods, and the mountains behind it. So that Digory felt just as sure as you that they were all going to live happily ever after. But perhaps you would like to know just one or two things more.
Polly and Digory were always great friends and she came nearly every holidays to stay with them at their beautiful house in the country; and that was where she learned to ride and swim and milk and bake and climb.
In Narnia the Beasts lived in great peace and joy and neither the Witch nor any other enemy came to trouble that pleasant land for many hundred years. King Frank and Queen Helen and their children lived happily in Narnia and their second son became King of Archenland. The boys married nymphs and the girls married woodgods and river-gods. The lamp-post which the Witch had planted (without knowing it) shone day and night in the Narnian forest, so that the place where it grew came to be called Lantern Waste; and when, many years later, another child from our world got into Narnia, on a snowy night, she found the light still burning. And that adventure was, in a way, connected with the ones I have just been telling you.
It was like this. The tree which sprang from the Apple that Digory planted in the back garden, lived and grew into a fine tree. Growing in the soil of our world, far out of the sound of Aslan's voice and far from the young air of Narnia, it did not bear apples that would revive a dying woman as Digory's Mother had been revived, though it did bear apples more beautiful than any others in England, and they were extremely good for you, though not fully magical. But inside itself, in the very sap of it, the tree (so to speak) never forgot that other tree in Narnia to which it belonged. Sometimes it would move mysteriously when there was no wind blowing: I think that when this happened there were high winds in Narnia and the English tree quivered because, at that moment, the Narnia tree was rocking and swaying in a strong south-western gale. However, that might be, it was proved later that there was still magic in its wood. For when Digory was quite middle-aged (and he was a famous learned man, a Professor, and a great traveller by that time) and the Ketterleys' old house belonged to him, there was a great storm all over the south of England which blew the tree down. He couldn't bear to have it simply chopped up for firewood, so he had part of the timber made into a wardrobe, which he put in his big house in the country. And though he himself did not discover the magic properties of that wardrobe, someone else did. That was the beginning of all the comings and goings between Narnia and our world, which you can read of in other books.
When Digory and his people went to live in the big country house, they took Uncle Andrew to live with them; for Digory's Father said, “We must try to keep the old fellow out of mischief, and it isn't fair that poor Letty should have him always on her hands.” Uncle Andrew never tried any Magic again as long as he lived. He had learned his lesson, and in his old age he became a nicer and less selfish old man than he had ever been before. But he always liked to get visitors alone in the billiard-room and tell them stories about a mysterious lady, a foreign royalty, with whom he had driven about London. “A devilish temper she had,” he would say. “But she was a dem fine woman, sir, a dem fine woman.”
