They have all been put to shame by a boy who, while playing truant, travelled 1600 miles. He hitch hiked to Dover and, towards evening, went into a boat to find somewhere to sleep. When he woke up next morning, he discovered that the boat had, in the meantime, travelled to Calais. No one noticed the boy as he crept off. From there, he hitchhiked to Paris in a lorry. The driver gave him a few biscuits and a cup of coffee and left him just outside the city. The next car the boy stopped did not take him into the centre of Paris as he hoped it would, but to Perpignan on the FrenchSpanish border. There he was picked up by a policeman and sent back to England by the local authorities. He has surely set up a record for the thousands of boys who dream of evading school.hour, he had great difficulty in controlling the car because a tyre burst during the first run. After his attempt, Campbell was disappointed to learn that his average speed had been 299 miles per hour. However, a few days later, he was told that a mistake had been made. His average speed had been 301 miles per hour. Since that time, racing drivers have reached speeds of over 400 miles an hour. FollowingLittle boys who play truant from school are unimaginative.

My parents, used to live in South America and I used to fly there from Europe in the holidays. An airhostess would take charge of me and I never had an unpleasant experience. I am used to travelling by air and only on one occasion have I ever felt frightened. After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport. While we were waiting to land, an airhostess told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened. Later we learnt that there was a very important person on board. The po
