He held his breath and turned his head slowly to the right. For a long time the sound increased only very slightly. And then, there broke upon the general stillness a series of abrupt explosions. Pfft--Pfft--Pfft--Pfft--Pfft-- And the other noise, the purring and whirring, resumed this time so close to Arthur that he instinctively, and half in fear, arose from the stile and looked around him. But the tall hedges sweeping away on either side made it difficult to see anyone who might be approaching under their cover. There was a pause. Then a different sound. Click--click--clickerty click--clicker clicker--clicker-- And so on, becoming louder and louder until at last it stopped, and its place was taken by the dull pitter-patter of footsteps coming nearer and nearer. There was a little harsh snort that might have been intended for a sigh, and then a voice. "Oh dear, it is trying. It really is most dreadfully trying--" The next moment the Clockwork man came into full view round the corner of the hedge. He was swaying slightly from side to side, in his usual fashion, and his eyes stared straight ahead of him. He did not appear to notice Arthur, and did not stop until the latter politely stepped aside in order to allow him to pass. Then the Clockwork man screwed his head slowly round and appeared to become faintly apprehensive of the presence of another being. After a preliminary ear-flapping, he opened his mouth very wide. "You haven't," he began, with great difficulty, "seen a hat and wig?" "No," said Arthur, and he glanced at the Clockwork man's bald forehead and noticed something peculiar about the construction of the back of his head; there seemed to be some object there which he could not see because they were facing each other. "I'm sorry," he continued, looking rather hopelessly around him, "perhaps we could find them somewhere." "Somewhere!" echoed the Clockwork man, "that's what seems to me so extraordinary! Everybody says that. The idea of a thing being _somewhere_, you know. Elsewhere than where you expect it to be. It's so confusing." Arthur consulted his common sense. "Can't you remember the place where you lost them," he suggested. A faint wrinkle of perplexity appeared on the other's forehead. He shook his head once "Place. There, again, I can't grasp that idea. What is a place? And how does a thing come to be in one place and not in another?" He jerked a hand up as though to emphasise the point. "A thing either is or it isn't. It can't be in a _place_." "But it must be somewhere," objected Arthur, "that's obvious." The Clockwork man looked vaguely distressed. "Theoretically," he agreed, "what you say is correct. I can conceive it as a mathematical problem. But actually, you know, it isn't at all obvious."
