Now Commander Caractacus Pott was an explorer and an inventor and that may have been the reason why the Pott family was not very rich. Exploring places and inventing things can be very exciting indeed, but it is only very seldom that, in your explorations, you discover a really rare butterfly or animal or insect or mineral or plant that people will pay money to see, and practically never that you discover real treasure, like in books—gold bars and diamonds and jewels in an old oak chest.
