"It was while we were in that pigeon-place, where the hen was. They look like rows and rows of little square holes, where the pigeons used to live I mean, but when you put your hand in they're quite big inside, all scooped out, lots of room for both pigeons and all their eggs. And one row hooks round inside one way and the other the other. I discovered that when I put my hand in, and I turned round to tell Derry. And do you know, Uncle George, he's got such a funny name for that place. He calls it the Tower of Oblivion. I didn't know what oblivion was, so I didn't know what he meant just at first, but I think it's a splendid name for it now. You see----" "You were saying that you turned round to tell him something." "I was just coming to that. So I turned round, and at first I had rather a fright, because I couldn't see him. I thought he'd gone, but I didn't see how he could, because there was only that one little way in and I was standing close to it. Then I saw him behind the bushes and things, all among the nettles, and his head was against the wall. I made a noise, but he didn't seem to hear me. So then I touched him. "'What's the matter, M'sieur Arnaud?' I said. 'Is something the matter?' "Well, he didn't move, Uncle George. For ever so long he didn't move. Then he turned round, and oh, his poor eyes! I don't mean he was crying. He didn't cry once all the time. But he made me so anxious I didn't know what to do. "'What is the matter, M'sieur Arnaud? Do tell me what's the matter!' I said. "'You mustn't call me that,' he said. 'It isn't my name.' "'Not your name!' I said. 'But Sir George Coverham calls you that, and mother calls you that, and Sir George wouldn't have told mother so if it wasn't so, and they call you that where you live!' "'They do, and it isn't my name,' he said. 'I want to tell you my name,' he said. "Well, I thought it awfully funny everybody calling him something that wasn't his name. So I said, 'Well, what _is_ your name?' "'Rose,' he said. "'What besides Rose?' I said. "'Derwent,' he said. 'Derwent Rose. But George calls me Derry.' "'George? Do you mean Sir George Coverham?' I said. "'Yes. I sometimes call him George,' he said. "And then, Uncle George, he put his head against the wall again and went on saying to himself, 'The Tower of Oblivion, the Tower of Oblivion,' over and over again."
