He gazed on it for a moment in ecstasy and then turned to shut the door. As he did so he felt a slight strange giddiness and stood a moment with his hand to his head. He turned and went again towards the city, and when he was close to it he gave a little cry, hastily stifled, for fear some one should hear him and come down and send him to bed. He stood and gazed about him bewildered and, once more, rather giddy. For the city had, in a quick blink of light, followed by darkness, disappeared. So had the drawing-room. So had the chair that stood close to the table. He could see mountainous shapes raising enormous heights in the distance, and the moonlight shone on the tops of them. But he himself seemed to be in a vast, flat plain. There was the softness of long grass round his feet, but there were no trees, no houses, no hedges or fences to break the expanse of grass. It seemed darker in some parts than others. That was all. It reminded him of the illimitable prairie of which he had read in books of adventure. 'I suppose I'm dreaming,' said Philip, 'though I don't see how I can have gone to sleep just while I was turning the door handle. However----' He stood still expecting that something would happen. In dreams something always does happen, if it's only that the dream comes to an end. But nothing happened now--Philip just stood there quite quietly and felt the warm soft grass round his ankles. Then, as his eyes became used to the darkness of the plain, he saw some way off a very steep bridge leading up to a dark height on whose summit the moon shone whitely. He walked towards it, and as he approached he saw that it was less like a bridge than a sort of ladder, and that it rose to a giddy height above him. It seemed to rest on a rock far up against dark sky, and the inside of the rock seemed hollowed out in one vast dark cave. [Illustration: Beyond it he could see dim piles that looked like churches and houses.]
