The Ancient Law by Ellen Glasgow

In the morning, after a short sleep on the hard plush seat, he awoke with a shooting pain in his head. When the drowsiness of exhaustion had overcome him, he remembered, he had been idly counting the dazzling electric lights of a town through which they were passing. By the time he had reached "twenty-one" he had dropped off into unconsciousness, though it seemed to him that a second self within him, wholly awake, had gone on through the night counting without pause, "twenty-two, twenty-three, twenty-four, twenty-five -- " Still in his brain the numbers went on, and still the great globular lights flashed past his eyes.

Struggling awake in the gray dawn, he lay without changing his position, until the mist gave place slowly to the broad daylight. Then he found that they were approaching another town, which appeared from a distant view to resemble a single gigantic factory, composed chiefly of a wilderness of chimneys. When he looked at his watch, he saw that it was eight o'clock; and the conductor passing through the coach at the instant, informed the passengers generally that they must change cars for the West. The name of the town Ordway failed to catch, but it made so little difference to him that he followed the crowd mechanically, without inquiring where it would lead him. The pain in his head had extended now to his chest and shoulders, and presently it passed into his lower limbs, with a racking ache that seemed to take from him the control of his muscles.
