She came so quietly, or else he was so deep in thought, that he did not hear her. For a minute she stood there in the library door.

He was sitting in his Morris chair, his hands upon the arms of it, his head leaning back. His eyes were closed, one could not tell in that moment that he was blind, but it was more than the dimness, the blankness in his eyes, more than scarred eyeballs, made for the change in Karl's face. He and life did not dwell together as they had once; a freedom and a gladness and a sureness had gone. The loss of those things meant the loss of something fundamentally Karl. And the sadness—and the longing—and the marks of struggle which the light of courage could not hide!

She choked a little, and he heard her, and held out his hand, with a smile. It was the smile which came closest to bridging the change. He was very close to being Karl when he smiled at her like that.

She sat down on the low seat beside him, as was their fashion. "Lazy man,"—brushing his hand tenderly with her lips—"wouldn't help his wife cut the grass!"

She wondered, as they sat there in silence, how many lovers had loved that hour. It seemed mellowed with the dreams it had held from the first of time. Ever since the world was very young, children of love had crept into the twilight hour and claimed it as their own. Perhaps the lovers of to-day love it because unto it has been committed the soul of all love's yesterdays.

She and Karl had loved it from the very first: in those days when they were upon the sea, those supreme days of uncomprehended happiness. They sat in the twilight then and watched day withdraw and night spread itself over the waters. They loved the mystery of it, for it was one with the mystery of their love; they loved it for reasons to be told only in great silences, knowing unreasoningly, that they were most close together then.

And after that they came to love the twilight for the things it bequeathed them. "Don't you remember," he would say, "we left it just as the sun was setting. Aren't you glad we can remember it so?" It was as if their love could take unto itself most readily that which came to it in the mystic hour of closing day.

And when they returned, during that first year of joy in their work, they loved the hour of transition as an hour of rest. Their day's work was done; in the evening they would study or read or in some way occupy themselves, but because they had worked all through the day they could rest for a short time in the twilight. And they would tell of what they had done; of what they hoped to do; if there had been discouragements they would tell of them, and with the telling they would draw away. In the light of closing day the future's picture was unblurred. They loved their hour then as true workers love it; it was good to sink with the day to the half lights of rest and peace.

Now it was all different, but they clung to their love for it still. Through the heart of the day, during those hours which from his early boyhood had been to him working hours, this removal from life brought to the man a poignancy of realisation which beat with undiminishing force against the wall of his endurance. It was when he finished his breakfast and the day's work would naturally begin that it came home to him the hardest. They would go into the library, and Ernestine would read to him—how she delved into the whole storehouse of literature for things to hold him best—and how great her joy when she found something to make the day pass a little less hard than was the day's wont! He would listen to her, loving her voice, and trying to bring his mind to what she read, but all the while his thoughts reaching out to what he would be doing if his life as worker were not blotted out. The call of his work tormented him all through the day, and the twilight was the time most bearable because it was an hour which had never been filled with the things of his work. In that short hour he sometimes, in slight measure found, if not peace, cessation from struggle. "This is what I would be doing now," he told himself, and with that, when the day had not drawn too heavily upon him, he could rest a little, perhaps, in some rare moments, almost forget.

But to-night the spell of the hour was passing him by. Ernestine saw that in the restless way his hand moved away from hers, the nervous little cough, the fretted shaking of the head. She understood why it was; the fall quarter at the university opened that day. It would have marked the beginning of his new year's work. Very quietly she wiped the tears from her cheek. She tried never to let Karl know that they were there.
