Amidst all this anxiety the brothers led a most solitary and gentle life. Pierre himself now spent most of his time at home. The first days of March had come, and precocious springtide imparted delightful charm and warmth to the little garden. Guillaume, however, since quitting his bed, had more particularly installed himself in his father's old laboratory, now transformed into a spacious study. All the books and papers left by the illustrious chemist were still there, and among the latter Guillaume found a number of unfinished essays, the perusal of which greatly excited his interest, and often absorbed him from morning till night. It was this which largely enabled him to bear his voluntary seclusion patiently. Seated on the other side of the big table, Pierre also mostly occupied himself with reading; but at times his eyes would quit his book and wander away into gloomy reverie, into all the chaos into which he still and ever sank. For long hours the brothers would in this wise remain side by side, without speaking a word. Yet they knew they were together; and occasionally, when their eyes met, they would exchange a smile. The strong affection of former days was again springing up within them; their childhood, their home, their parents, all seemed to live once more in the quiet atmosphere they breathed. However, the bay window overlooked the garden in the direction of Paris, and often, when they emerged from their reading or their reverie, it was with a sudden feeling of anxiety, and in order to lend ear to the distant rumbling, the increased clamour of the great city. On other occasions they paused as if in astonishment at hearing a continuous footfall overhead. It was that of Nicholas Barthes, who still lingered in the room above. He seldom came downstairs, and scarcely ever ventured into the garden, for fear, said he, that he might be perceived and recognised from a distant house whose windows were concealed by a clump of trees. One might laugh at the old conspirator's haunting thought of the police. Nevertheless, the caged-lion restlessness, the ceaseless promenade of that perpetual prisoner who had spent two thirds of his life in the dungeons of France in his desire to secure the liberty of others, imparted to the silence of the little house a touching melancholy, the very rhythm as it were of all the great good things which one hoped for, but which would never perhaps come.
