And then Arthur was quite sure about something that he had been vaguely hearing for some moments. It sounded like about a hundred alarum clocks all going off at once, muffled somehow, but concentrated. It was a sort of whirring, low and spasmodic at first, but broadening out into something more regular, less frantic. "What's that noise?" he demanded thoroughly frightened by now. "It's only my clock," said the other. He clambered over the hurdle, a little stiffly, as though not quite sure of his limbs. Except for a general awkwardness, an abrupt tremor now and again, he seemed to have become quite rational and ordinary. Arthur scarcely comprehended the remark, and it certainly did not explain the origin of that harassing noise. He gaped at the figure--less strange now, although still puzzling--and noticed for the first time his snuff-coloured suit of rather odd pattern, his boots of a curious leaden hue, his podgy face with a snub nose in the middle of it, his broad forehead surmounted by the funny fringe of the wig. His voice, as he went on speaking, gradually increased in pitch until it reached an even tenor. "Perhaps I ought to explain," he continued. "You see, I'm a clockwork man." "Oh," said Arthur, his mouth opening wide. And then he stammered quickly, "that noise, you know." The Clockwork man nodded quickly, as though recollecting something. Then he moved his right hand spasmodically upwards and inserted it between the lapels of his jacket, somewhere in the region of his waistcoat. He appeared to be trying to find something. Presently he found what it was he looked for, and his hand moved again with a sharp, deliberate action. The noise stopped at once. "The silencer," he explained, "I forgot to put it on. It was such a relief to be working again. I must have nearly stopped altogether. Very awkward. Very awkward, indeed." He appeared to be addressing the air generally. "The fact is, I need a thorough overhauling. I'm all to pieces. Nothing seems right. I oughtn't to creak like this. I'm sure there's a screw loose somewhere." He moved his arm slowly round in a circle, as though to reassure himself. The arm worked in a lop-sided fashion, like a badly shaped wheel, stiffly upwards and then quickly dropping down the curve. Then the Clockwork man lifted a leg and swung it swiftly backwards and forwards. At first the leg shot out sharply, and there seemed to be some difficulty about its withdrawal; but after a little practice it moved quite smoothly. He continued these experiments for a few moments, in complete silence and with a slightly anxious expression upon his face, as though he were really afraid things were not quite as they should be.
