Just then Old Hans the Grenadier stood by Viggo's side. When he had gained his breath after his hurried run, the old man cried very angrily: "If I did what you deserve I should have to whip you. Do you think it fit for a youngster like you to rush against a pack of wolves? If they had eaten you up alive before you had a chance to make a sound, what would you have said then?" "Then I would have said: 'One thing is a shame, and that is to turn your back before "retreat" is called,'" said Viggo, and looked sharply at the Grenadier. "Well said, my boy! The nose has not quite the right curve yet, but the eyes are there, and I do believe the heart, too," said Old Hans. He took the dog from Viggo, and went home with both of them. THE BLACK POND "Hurrah, the Black Pond is frozen! The ice is more than an inch thick, and there's a crowd of boys down there!" shouted one of Viggo's classmates one morning, as he thrust his frost-covered head through the door and swung his skates. It didn't take Viggo long before he got his skates down from the nail, and ran off with his friend. And he was so anxious to get down to the lake that he forgot to whistle for Allarm. But Allarm had a fine nose. Just as soon as he had swallowed his breakfast he understood that Viggo was gone. Then he ran out hunting through the yard for Viggo's trail, and when he noticed that it didn't lead to the school he knew he might follow. Then he rushed madly after him over the fields, and had caught up with him long before Viggo had reached the cottage of Hans the Grenadier, which lay close by the lake. One thing Viggo had promised his father before he got permission to go, and that was that he would be very careful and not skate far out from the shore. Near the middle of the lake there was an air hole through which warm air rose to the surface, and there the ice was never thick. And Viggo meant honestly to do what his father had told him, but now you shall hear what happened. When he came to the lake there was a crowd of boys there. There must have been twenty or more. Most of them had skates on, but some only slid on the ice. They shouted and laughed so that you could not hear yourself think. As soon as Viggo had put on his skates he began to look around. Most of the boys he knew, for he had raced with them before, and he felt that he could beat every one of them. But there was one boy who skated by himself, and seemed not to care about the others. He was much bigger than Viggo, and Viggo saw immediately that it would not be easy to beat him in a race. The boys called him Peter Lightfoot, and the name fitted him. He could do the corkscrew, skate backward as easily as forward, and lie so low and near the ice that he might have kissed it. But all this Viggo could do, too.
