For his part, the doctor took a walk of a couple of hours' duration each morning, ever alone, seeking, as it were, to tire and exhaust his grief. First of all, as soon as he had risen, he repaired to the cemetery, and knelt on the tomb of his wife and daughter, which, at all seasons, he decked with flowers. And afterwards he would roam along the roads, with tearful eyes, never returning home until fatigue compelled him. With a wave of the hand, Pierre accepted his proposal, and in perfect silence they went, side by side, down the sloping road. They remained for a long time without speaking; the doctor seemed more overcome than was his wont that morning; it was as though his chat with his dear lost ones had made his heart bleed yet more copiously. He walked along with his head bowed; his face, round which his white hair streamed, was very pale, and tears still blurred his eyes. And yet it was so pleasant, so warm in the sunlight on that lovely morning. The road now followed the Gave on its right bank, on the other side of the new town; and you could see the gardens, the inclined ways, and the Basilica. And, all at once, the Grotto appeared, with the everlasting flare of its tapers, now paling in the broad light. Doctor Chassaigne, who had turned his head, made the sign of the cross, which Pierre did not at first understand. And when, in his turn, he had perceived the Grotto, he glanced in surprise at his old friend, and once more relapsed into the astonishment which had come over him a couple of days previously on finding this man of science, this whilom atheist and materialist, so overwhelmed by grief that he was now a believer, longing for the one delight of meeting his dear ones in another life. His heart had swept his reason away; old and lonely as he was, it was only the illusion that he would live once more in Paradise, where loving souls meet again, that prolonged his life on earth. This thought increased the young priest's discomfort. Must he also wait until he had grown old and endured equal sufferings in order to find a refuge in faith? Still walking beside the Gave, leaving the town farther and farther behind them, they were lulled as it were by the noise of those clear waters rolling over the pebbles between banks shaded by trees. And they still remained silent, walking on with an equal step, each, on his own side, absorbed in his sorrows. "And Bernadette," Pierre suddenly inquired; "did you know her?"
