Mr. Evans works in Sydney. Last week he had a two-week holiday, but he didn't know where to go. He said to his friend Robert, “I hate the hot weather here, but I can't find a cool place in Australia. Where shall I take my holiday?” ‘That's easy,' said Robert, ‘You can go to Moscow. Snow and ice are covering the ground there now. ' Mr. Evans agreed with his friend. He bought a plane ticket and soon got to Moscow. He had a happy time there. But one day he got into trouble. After lunch he went to a park outside the city. He saw a dog following him while he was walking past a house. It was hungry and wished him to give it some food to eat, But he had no piece of bread or cake in his pockets. He tried to send it away, but it began to bark at him. Just at that moment, he saw a stone on the ground. He tried to pick it up but he coul dn't. ‘How strange these Russians are!' Mr. Evans said to himself, ‘They do not tie their dogs, but firmly tie the stones!'
