Night falls rapidly. Cosmo lights the lamp and spreads out his map on the colourful carpet. He points to one of the many white spaces and says: We are now in Jericho. The oasis is a four-hour walk in length and a one-hour walk in breadth, and of a rare beauty perhaps matched only by the paradisal orchard of Damascus - le merveilleux verger deDamas. The people here have all they want. Whatever they sow grows immediately in this soft, fertile soil . The glorious gardens flower forever.
