There was one inconsistancy in this scheme of things: Just as the train emerged from a deep valley of slag-hills and swung into a long curve, passengers on the left side had a panoramic view of the city--a frozen scene of battle between geometrical monsters, made remote and obscure by the dust of a thousand thousand merely human struggles, too small to be visible from the crusty windows of the train by the merely human eye. They had about one second in which to absorb this vision of corporate purpose. Then they were plunging into a final stretch of tunnel to the center of the city itself, where no surface was ever more than fifteen paces away and where there were no horizons at all. Dewforth was excited by this view even though it reached him in a fragmentary and subliminal way. Day after day he told himself that he would have all his faculties at the ready before the train swung into the curve. But morning after morning he was still emerging from the stale fumes of the preceding night's beer, or he allowed himself to be hypnotized by the sound of the wheels or fascinated by the jiggling of another passenger's earlobe at that critical moment. The train had always entered the clangorous colon of the city before this resolve could crystallize in his mind, and he was left with an impression which lay somewhere in the scale of reality between the after-image of a light bulb and the morning memory of a fever-dream. He could never have described the scene except in loose generalities about buildings of contrasting height and unemphatic color. * * * * * The single memorable feature of the panorama, looming above the rest, was not even a building. It eluded all familiar categories. It was, like the other components of the picture, rectangular; but it was a displaced rectangle. A shining thread of morning sky could be seen beneath it. It was only logical to suppose that it stood on legs of some kind--a complicated process of girders. The upper part appeared to be made of corrugated metal, but, as with the matter of the legs, it was impossible to separate what was actually seen and what was merely inferred. The only other structures Dewforth had seen which resembled it at all were water towers and shipyard cranes, but these had been mere toys compared with the thing that hovered over the center of the city. Its purpose could not be guessed, but what disturbed Dewforth more was the fact that he could not be sure that it existed. He was a precision draftsman, more or less resigned to deteriorating eyesight, and his usual abstracted state of mind during that segment of his day had also to be considered. He hoped that someone else would mention the structure. Once--only once--a man sitting on the opposite seat had made a comment which could have applied to it. "It turned," he said, just as the tunnel swallowed the train.
