Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired,Howe slept badly.
