I thought this was a ripping plan, for it is horrid when Santa Claus forgets you, and your stockings hang all limp and flat, like mine did last year. And I made up my mind, then and there, that next Christmas there should be a tree for all the littlest and grubbiest children in my old home. While Father was at the hospitals with the Herr Professor, I stayed with Rudolf and Gretchen, two of his grandchildren--fat little things with big blue eyes, who stared at me as if I had seven heads when I told them about the Korrigans. Gretchen believed in Fairies of all kinds, but Rudolf only in Dwarfs and Giants. He even said that Santa Claus was just his own father dressed up, and declared he had seen his old brown pipe peeping out of Santa Claus' pocket the last time he paid them a visit. Gretchen said that if so, Santa Claus had taken away the old brown pipe to bring a lovely new one in its place, and Rudolf told her girls knew too much. They were both angry by this time, and their faces looked very red. So I thought we had better talk about Dwarfs and Giants. "Grandfather says there are no Giants now," Rudolph said seriously, "but there are plenty of Dwarfs in the hill which looks down on the forest. I saw one there myself last summer; he ran away and wouldn't speak to me, as if he were afraid." Without saying anything to Rudolf, who might have wanted to come too, I started for the hill directly after dinner, while he and Gretchen were arguing again over the pipe and Santa Claus. The Professor's house was just at the end of the town, so I didn't have far to go; but the hill took much longer to climb than I thought it would, and I was quite out of breath when I reached the top and sat down on a flat white stone. As I looked about me, I swung my foot, and it tapped against a biggish rock that was just in front. The third time that I did this, a little brown man hopped briskly out of a crevice and stood before me. He wore a bright red coat trimmed with green buttons, and carried in his hand a close-fitting cap of grey. [Illustration: Fat little things, with big blue eyes.] "Gently, gently, good child!" he cried. "One knock is enough, if we want to hear it, for our ears are as keen as we could wish. Why did you call me, and what would you have?" "I would hear of you, and of your kinsmen, Master Dwarf!" I said. "I am a Christmas Child, and the Fairies are all my friends." At this he bowed, and said he was glad to meet me, nodding his head with a sort of grunt as I told him where I had met Titania. "If it be your pleasure," he said, looking round to see that no one was near but me, "I will take you within the hill, and introduce you to my wife. The ground whereon you stand is hollow, as you will soon perceive, and we are less than a stone's throw from my palace."
