Inside his head during this last hour he felt as if a sort of piston-rod from a cylinder had been making firm strokes onto some bleeding, mangled nerve. The end of the piston-rod was fitted sometimes with a blunt hammer, so that it crushed the nerve, sometimes with a sharp needle-point which went deeper, and seemed to penetrate the very home and heart of pain. Then perhaps the piston-rod would cease for a few seconds, while an iron-toothed, rusty rake collected the smashed fragments of nerve together again, so that the hammer should not fail to hit them squarely, and made a neat little pyramid of the pieces on the place where it would descend. This raking together (the image was so vivid to him that he almost believed that it actually took place) was about the worst part. He knew that in a minute the hammer would begin again. But now, a few moments only after he had taken his dose, the change began. Though the hammer did not cease to fall, its blows no longer produced pain. They produced instead a warm, tingling sensation, like that which the hand feels when it spreads out icy fingers to a friendly blaze. And that tingling warmth felt its way gradually through his head, passed down his neck, and slowly flooded body and limbs to toe and finger tip. He forgot what pain meant; he was unable to realise even before the piston-rod ceased to beat what it connoted, knowing only what the oncoming of this tide of physical bliss was like. Every sense, too, was quickened and stimulated. The sun that still shone in at his windows burned with a ruddier and more mellow light. The glory of it was soft but incredibly brilliant, and to his quickened sense of smell the air that came in through the open sash was redolent with the honey-scent of warm heather. The blind had been a little drawn down over the top of the window, but whereas, when he was dressing for dinner an hour ago, the sound of it flapping against the frame was a fretting and irritating thing, it now seemed to him to give out flute-like and vibrating notes, while the taste of the cigarette which he had lit five minutes ago, and brought up with him, had a flavour new and exquisite. The present moment, and the sensations of it, were all quickened into the vividness of dream-life, while it was but vaguely that he remembered that downstairs Maud was sitting with a very pleasant American fellow who had come to dinner. At dinner he remembered, but again vaguely, that he was not sure if he liked him; now he appeared to be the most charming of companions. But with the gates of Paradise here upstairs flung wide for his reception, he could not fix his mind very clearly on him. No doubt, if he made an effort, he could recall more about him, and remember his name, which just now eluded him; but an effort was the one thing he certainly would not make, since it might disturb or destroy this perfect equilibrium on which he was balanced. And there was really
