The Swiss Family Robinson
I loved this book, though. A lot of the flora and fauna which the Robinson family found on their island was improbable - elephants on an island? Bison? Plus so many types of birds. That many birds would mean being close to a major landmass, and hence in shipping lanes, and hence being found much sooner. But I loved the book anyway. I wish I could be as knowledgeable as Mr. Robinson - he had an encyclopedic knowledge of, well, everything. He knew how to make drawbridges, looms, treehouses, husbandry, farming, slaughtering and wide variety of animals, etc.
I can see why this book is a classic. It's a fun read.
