As she lay in her berth, staring at the shadows overhead, the rush of the wheels was in her brain, driving her deeper and deeper into circles of wakeful lucidity. The sleeping-car had sunk into its night-silence. Through the wet window-pane she watched the sudden lights, the long stretches of hurrying blackness. Now and then she turned her head and looked through the opening in the hangings at her husband’s curtains across the aisle.... She wondered restlessly if he wanted anything and if she could hear him if he called. His voice had grown very weak within the last months and it irritated him when she did not hear. This irritability, this increasing childish petulance seemed to give expression to their imperceptible estrangement. Like two faces looking at one another through a sheet of glass they were close together, almost touching, but they could not hear or feel each other: the conductivity between them was broken. She, at least, had this sense of separation, and she fancied sometimes that she saw it reflected in the look with which he supplemented his failing words. Doubtless the fault was hers. She was too impenetrably healthy to be touched by the irrelevancies of disease. Her self-reproachful tenderness was tinged with the sense of his irrationality: she had a vague feeling that there was a purpose in his helpless tyrannies. The suddenness of the change had found her so unprepared. A year ago their pulses had beat to one robust measure; both had the same prodigal confidence in an exhaustless future. Now their energies no longer kept step: hers still bounded ahead of life, preëmpting unclaimed regions of hope and activity, while his lagged behind, vainly struggling to overtake her. When they married, she had such arrears of living to make up: her days had been as bare as the whitewashed school-room where she forced innutritious facts upon reluctant children. His coming had broken in on the slumber of circumstance, widening the present till it became the encloser of remotest chances. But imperceptibly the horizon narrowed. Life had a grudge against her: she was never to be allowed to spread her wings.
