THE ENTIRE TRAIN, amounting to some two dozen wagons, proceeded west through Halle and other cities in the Saxon plain. Giant stone towers with dunce-cap rooves had been raised over city gates so that the burghers could see armies or Vagabond-hordes approaching in time to do something about it. A few days past Halle, the ground finally started to rise up out of that plain and (like one of the Doctor's philosophical books) to channel them this way and that, making them go ways they were not especially inclined to. It was a slow change, but one morning they woke up and it was no longer disputable that they were in a valley, the most beautiful golden valley Jack had ever seen, all pale green with April's first shoots, thickly dotted with haystacks even after cattle had been reducing them all winter long. Broad fells rose gently but steadily from this valley and developed, at length, into shapes colder and more mountainous – ramps built by giants, leading upwards to mysterious culminations. The highest ridge-lines were indented with black shapes, mostly trees; but the Saxons had not been slow to construct watch-towers on those heights that commanded the most sweeping views. Jack couldn't help speculating as to what they were all waiting for. Or perhaps they sparked fires in them at night to speed strange information over the heads of sleeping farmers. They passed a placid lake with what had been a brown stone castle avalanching into it; wind came up and raised goose-bumps on the water, destroying the reflection.
