Little Story about Lincoln for Sunday Evening

Uncle Lincoln was a pilot who flew all round the world.
One day, the postman knocked at the door. In his hand he had a big dried brown bean pod, with an elastoplast stuck on it bearing our address, and a stamp. It was a Brazilian bean pod which rattled when you shook it, because it was full of dried Brazilian beans, and it was a percussion instrument.
Later, Uncle Lincoln told us that the Post Office had refused to accept it because, as they said, it was not wrapped up. 'Aha' said Uncle Lincoln,'It is the beans that I am sending, and they are wrapped up in the bean pod!'. 'Oh, that's all right then', said the Post Office, and accepted the package.
