Of course the kind-hearted German could not refuse such a general request. Besides, he liked to tell stories. Taking his long pipe out of his mouth, he laid it down on the ground beside him. Then he cleared his throat and began to speak. "Look above you, friends. Do you see that mark on the rocky platform overhead? I noticed it as soon as I got here. It made me think of a wild spot in the Hartz Mountains where there is just such a mark. The people call it 'The Horse's Hoof-print.' I will tell you how they explain its coming there. "Once upon a time there was a beautiful princess. Her name was Brunhilda, and she lived in Bohemia. She lived a gay and happy life, like most young princesses, till one day a handsome prince arrived at her father's palace. He was the son of the king of the Hartz country. "Of course, you can all guess what happened. The prince fell in love with the princess, and she returned his love. The day was set for the wedding, and the young prince went home to prepare for the great event. "But he had been gone only a short time when a powerful giant arrived at Brunhilda's home. He came from the far north. His name was Bodo. "He asked for the princess in marriage, but her heart had already been given away. She did not care for the giant, even though he gave her the most elegant presents,--a beautiful white horse, jewels set in gold, and chains of amber. "'I dare not refuse the giant,' said Brunhilda's father. 'He is very powerful, and we must not make him angry. You must marry him, my daughter, in three days.' "The poor maiden wept bitterly. It seemed as though her heart would break. But she was a clever girl, and she soon dried her tears and began to think of some plan by which she might yet be free. She began to smile upon the giant and treat him with great kindness. "'I should like to try the beautiful horse you brought me,' she said to him. He was much pleased. The horse was brought to the door. The princess mounted him and rode for a time up and down in front of the palace. "The very next day was that set apart for the wedding. The castle was filled with guests who feasted and made merry. The giant entered into everything with a will. He laughed till the floors and walls shook. Little did he think what was taking place. For the princess slipped out of the castle when no one was watching, hurried into the stable, and leaped upon the back of her swift white horse. "'Lower the drawbridge instantly,' she called to the guard. She passed over it, and away she flew like the wind. "You were too late, too late, O giant, when you discovered that Brunhilda was missing. "He flew out of the castle, and on the back of his own fiery black horse he dashed after the runaway princess.
