So they ran faster and faster till it was more like flying than running， and even the Eagle overhead was going no faster than they. And they went through winding valley after winding valley and up the steep sides of hills and， faster than ever， down the other side， following the river and sometimes crossing it and skimming across mountainlakes as if they were living speed.boats， till at last at the far end of one long lake which looked as blue as a turquoise， they saw a smooth green hill. Its sides were as steep as the sides of a pyramid and round the very top of it ran a green wall： but above the wall rose the branches of trees whose leaves looked like silver and their fruit like gold.
“Further up and further in！” roared the Unicorn， and no one held back. They charged straight at the foot of the hill and then found themselves running up it almost as water from a broken wave runs up a rock out at the point of some bay. Though the slope was nearly as steep as the roof of a house and the grass was smooth as a bowling green， no one slipped.
