The light sifted down out of the sky like motes and flakes of ash from a burning city. At some point there was suddenly enough of it that he could make sense of the blobs and vestiges that, for the last hour or so, had marred the darkness. He stopped to look round. He had imagined, until now, that they had been marching across open ground, diverting around the occasional wood. But it was not like that. Trees grew more or less densely everywhere, and made it impossible to see more than a stone’s throw in any direction, except where a hill rolled up in the distance. Through the mottled shadow of the wood meandered a pale river: a way paved with grass that was becoming prickly and tinder-like in the summer heat. This chalky soil was as powerless to retain moisture as the fingers of a skeleton to hold money. It set off a hue and cry in his mind: he had marched a company into a high place where ponds and streams would not exist! In a few hours they would be out of water! He silenced these alarms by means of elaborate thinking and exhausting mental effort; ten paces later they started back up again, and reigned over his mind for an age. The thoughts became dry and worn-out, like straw that has been slept on too many times, and finally disintegrated in the first clear light of the morning.
