He began to be intensely and minutely conscious of the world outside--so entirely conscious that he lost all perception of that at which he stared; whether it was the paper, or the strong, motionless hand, or the introspective face, he was afterwards unaware. But he heard all the quiet roar of the London evening, and was able to distinguish even the note of each instrument that helped to make up that untiring, inconclusive orchestra. Far away to the northwards sounded a great thoroughfare, the rolling of wheels, a myriad hoofs, the pulse of motor vehicles, and the cries of street boys; upon all these his attention dwelt as they came up through the outward windows into that dead silent, lamp-lit room of which he had lost consciousness. Again a hansom came up the street, with the rap of hoofs, the swish of a whip, the wintry jingle of bells.... He began gently to consider these things, to perceive, rather than to form, little inward pictures of what they signified; he saw the lighted omnibus, the little swirl of faces round a news-board. Then he began to consider what had brought him here; it seemed that he saw himself, coming in his dark suit across the park, turning into the thoroughfare and across it. He began to consider Amy; and it seemed to him that in this intense and living silence he was conscious of her for the first time without sorrow since ten days ago. He began to consider. * * * * * Something brought him back in an instant to the room and his perception of it, but he had not an idea what this was, whether a movement or a sound. But on considering it afterwards he remembered that it was as that sound is that wakes a man at the very instant of his falling asleep, a sharp momentary tick, as of a clock. Yet he had not been in the least sleepy. On the contrary, he perceived now with an extreme and alert attention the hand on the paper; he even turned his head slightly to see if the pencil had moved. It was as motionless as at the beginning. He glanced up, with a touch of surprise, at his hostess's face, and caught her in the very act of turning her eyes from his. There was no impatience in her movement: rather her face was of one absorbed, listening intently, not like the bearded face opposite, introspective and intuitive, but eagerly, though motionlessly, observant of the objective world. He looked at Mrs. Stapleton. She too bore the same expression of intent regarding thought on her usually rather tiresome face. Then once again the silence began to come down, like a long, noiseless hush. This time, however, his progress was swifter and more sure. He passed with the speed of thought through those processes that had been measurable before, faintly conscious of the words spoken before the sitting began-- "... If possible, the silence of thought."
