Once upon a time there was a King who reigned over a country as yet, for a reason you may learn later on, undiscovered-a most lovely country, full of green dales and groves of oak, a land of dappled meadows and sweet rivers, a green cup in a circlet of mountains, in whose shadow the grass was greenest; and the only road to enter the country lay up steep, boiling waterfalls, and thereafter through rugged passes, the channels that the rivers had cut for themselves. Therefore, as you may imagine, the dwellers in the land were little troubled by inroads of hostile nations; and they lived peaceful lives, managing their own affairs, and troubling little about the rest of the world.
