There was nothing important in them. The boxes were full many questions, but they did not learn anything important. Pearson's Map. Then Salahadin had an idea. Who carried these boxes to this room?He asked the manager. The manager brought back two porters. Did you carry these boxes into this room? Salahadin asked the porters. Yes they replied. How many boxes were there? Six boxes, replied the first porters. I carried three and my friend carried three. Salahadin looked at the boxes. There were six of them. No one had taken a box. Wait a moment, said the second porter. You're wrong. There were seven boxes. You carried three. But that makes six boxes,not seven,said Ahmed, with a smile. You can't count. I can count, replied the porter. There were seven boxes. Mr Pearson carried one into the room himself. It was a heavy box,but it was smaller than the others. That is the box which is missing,Salahadin said to Ahmed.
