They say the world is flat and supported on the back of four elephants who themselves stand on the back of a giant turtle. They say that the elephants, being such huge beasts, have bones of rock and iron, and nerves of gold for better conductivity over long distances. They say that the fifth elephant came screaming and trumpeting through the atmosphere of the young world all those years ago and landed hard enough to split continents and raise mountains. No one actually saw it land, which raised the interesting philosophical question: when millions of tons of angry elephant come spinning through the sky, and there is no one to hear it, does it - philosophically speaking - make a noise? And if there was no one to see it hit, did it actually hit? In other words, wasn"t it just a story for children, to explain away some interesting natural occurrences? As for the dwarfs, whose legend it is, and who mine a lot deeper than other people, they say that there is a grain of truth in it. On a clear day, from the right vantage point on the Ramtops, a watcher could see a very long way across the plains. If it was high summer, they could count the columns of dust as the ox trains plodded on, at a top speed of two miles an hour, each pair pulling a train of two wagons carrying four tons apiece.
