Often now she did not answer, intrenching herself behind her fierce convictions, not wishing to dispute. But doubtless he had this time touched her beliefs to the quick.

“There is no reality,” she answered sharply.

The doctor, amused by this bold philosophy from this big child, laughed.

“Yes, I know,” he said; “our senses are fallible. We know this world only through our senses, consequently it is possible that the world does not exist. Let us open the door to madness, then; let us accept as possible the most absurd chimeras, let us live in the realm of nightmare, outside of laws and facts. For do you not see that there is no longer any law if you suppress nature, and that the only thing that gives life any interest is to believe in life, to love it, and to put all the forces of our intelligence to the better understanding of it?”

She made a gesture of mingled indifference and bravado, and the conversation dropped. Now she was laying large strokes of blue crayon on the pastel, bringing out its flaming splendor in strong relief on the background of a clear summer night.

But two days later, in consequence of a fresh discussion, matters went still further amiss. In the evening, on leaving the table, Pascal went up to the study to write, while she remained out of doors, sitting on the terrace. Hours passed by, and he was surprised and uneasy, when midnight struck, that he had not yet heard her return to her room. She would have had to pass through the study, and he was very certain that she had not passed unnoticed by him. Going downstairs, he found that Martine was asleep; the vestibule door was not locked, and Clotilde must have remained outside, oblivious of the flight of time. This often happened to her on these warm nights, but she had never before remained out so late.

The doctor’s uneasiness increased when he perceived on the terrace the chair, now vacant, in which the young girl had been sitting. He had expected to find her asleep in it. Since she was not there, why had she not come in. Where could she have gone at such an hour? The night was beautiful: a September night, still warm, with a wide sky whose dark, velvety expanse was studded with stars; and from the depths of this moonless sky the stars shone so large and bright that they lighted the earth with a pale, mysterious radiance. He leaned over the balustrade of the terrace, and examined the slope and the stone steps which led down to the railroad; but there was not a movement. He saw nothing but the round motionless tops of the little olive trees. The idea then occurred to him that she must certainly be under the plane trees beside the fountain, whose murmuring waters made perpetual coolness around. He hurried there, and found himself enveloped in such thick darkness that he, who knew every tree, was obliged to walk with outstretched hands to avoid stumbling. Then he groped his way through the dark pine grove, still without meeting any one. And at last he called in a muffled voice:

“Clotilde! Clotilde!”

The darkness remained silent and impenetrable.

“Clotilde! Clotilde!” he cried again, in a louder voice. Not a sound, not a breath. The very echoes seemed asleep. His cry was drowned in the infinitely soft lake of blue shadows. And then he called her with all the force of his lungs. He returned to the plane trees. He went back to the pine grove, beside himself with fright, scouring the entire domain. Then, suddenly, he found himself in the threshing yard.
