"That is right," she said kindly. Then she stood and looked at them for quite a long time, while the boys grew shyer and shyer under her searching eyes. At last she spoke. "I am trying to feel your hearts," she said. "I can feel those of my own people at once, but yours are hard to understand." The boys did not know what she meant, but they were too shy to ask. She went on: "I should like to show you my Palace, but I must first know whether it is safe to trust you. Can you keep your word?" "I can!" cried both boys at once. The thought of seeing the Palace took away their shyness. "Well," said the Princess, "if I take you to the Palace, you must first promise not to tell anybody about it--not even your mothers. No mortal has ever before seen it, and I do not wish others to come to look for it; so you must not tell them about it. Do you promise?" The boys promised at once, and the Princess said: "I shall always hold you to that. See that you keep your word. Now come." They followed her a few steps up the side of the hill. Here she stopped, and tapped with her foot on the ground. Instantly a door flew open in the hillside, and they entered. The door swung to behind them, and they found themselves in the Princess's throne-room. It was a magnificent room, wide and lofty. The walls and roof and floor were all of glittering limestone, lit up by magic star-shaped lights of brilliant colours. In the centre stood a throne of solid gold, with a rug made of crimson flower-petals thrown half over it. "Don't the petals fade?" asked Roy as they admired the beautiful rug. "Nothing fades in my Palace," answered the Princess. She led them from room to room, talking kindly to them, and showing them quite proudly all the beauties of her home. It was indeed a wonderful Palace. Each room was different from all the others. In one the walls were made of gold, in another of silver, in another of opal, and in others of emerald or ruby or diamond, until one's eyes almost tired of the brilliance. The furniture was as beautiful as the walls, but the boys noticed that the chairs and tables and sofas and beds were all made very low, except those for the Princess herself. Indeed, so close to the ground were they that Charlie asked the Princess: "Are your people very little, Hill Princess?" The Princess laughed. "Come and see them," she said, and she led the way out to the back of the hill. Here they found themselves in an open space covered with grass and flowers and little bushes. On every side rose a high straight bank, covered with bush creepers, and behind the bank rose tall bush trees to hide the place from view. "This is our playground," said the Princess, "and here are my people." The boys looked round eagerly. All they could see were rabbits and hares and birds and insects--rabbits and hares and birds and insects everywhere--hundreds of them playing on the grass, amongst the flowers, in the bushes. The boys were puzzled.
