"No, Tivoli is one of the most famous parks in all the world," explained Anna. "It's right in the center of Copenhagen. In fact, it's right next to this station. Oh, I wish Father would hurry." When Greta first saw Tivoli she thought she was in fairyland. Surely it couldn't be real. The gay beds of flowers and the tinkling fountains and the colored lights among the trees all seemed to be part of a magic world. Besides all this beauty, Tivoli had many restaurants and theatres and places for concerts and games and other amusements. They had dinner in one of the outdoor restaurants, and Greta was so interested in watching the people as they passed by that she could hardly eat. After dinner they started to walk through the park and let Greta decide for herself what she would most enjoy. When they had gone only a little way they came to a large open stage, where a play was being given. They all stopped to watch it for a few minutes, and Greta wouldn't leave the spot. To her it was the most fascinating thing in Tivoli. Suddenly she noticed that something had gone wrong on the stage. The actors seemed confused and they hesitated over their lines. What could be the matter? Then, to her horror, she saw Chouse run across the stage and jump up on one of the actors. He was a young lad who looked something like Hans. Chouse soon saw his mistake and began wandering around the large stage as if he were lost. The audience laughed. They knew that this wasn't part of the play, and it seemed very funny to them. The minute that Greta saw Chouse she started toward the stage. Going around to the back, where the audience could not see her, she whistled and called to her dog. Chouse was glad to hear his name. Happily he ran off the stage at once and the play went on. "I think we had better go home now," said Anna's father, when Greta came back with the dog, "before Chouse gets into any more mischief." Greta's heart sank. They had barely gotten into Copenhagen--in fact, they hadn't even reached Anna's home yet--and Chouse had already gotten into mischief. What in the world was she going to do with him? CHAPTER X A DAY OF HAPPY SURPRISES "Anna, please don't walk so fast," begged Greta. The two girls were walking down Langelinie, the beautiful parkway along the ocean. Greta was much shorter than Anna and she could not walk nearly so fast. Then, too, she liked to stop and watch the boats coming into the harbor. The name Copenhagen means "merchants' harbor," and this city has one of the finest harbors in Europe. All kinds of ships, from tiny sailboats to large ocean liners, come here from all parts of the world. When they had gone a little farther, Greta wanted to sit down and rest. "Can't you walk just a tiny bit more, Greta? On the other side of this little bay there is someone I want you to meet." "Who, Anna?" "She is called 'Den Lille Havfrue,'" said Anna.
