Rhyme? And Reason? - Lewis Carroll - Bog

The Pingaree people never visited any other land but that of Rinkitink, and so there were few other lands that knew there was such an island. To the southwest was an island called the Isle of Phreex, where the inhabitants had no use for pearls. And far north of Pingaree-six days' journey by boat, it was said-were twin islands named Regos and Coregos, inhabited by a fierce and warlike people. Many years before this story really begins, ten big boatloads of those fierce warriors of Regos and Coregos visited Pingaree, landing suddenly upon the north end of the island.
