He renewed the effort at intervals, only to plunge deeper into misery. He felt the approaches of madness, and knew that his only hope was to walk till he was physically exhausted, so that he might come home almost fainting with fatigue, but ready to fall asleep the moment he got into bed. He passed the mornings in a kind of torpor, endeavoring to avoid thought, to occupy his mind with the pattern of the paper, with the advertisements at the end of a book, with the curious greyness of the light that glimmered through the mist into his room, with the muffled voices that rumbled now and then from the street. He tried to make out the design that had once coloured the faded carpet on the floor, and wondered about the dead artist in Japan, the adorner of his bureau. He speculated as to what his thoughts had been as he inserted the rainbow mother-of-pearl and made that great flight of shining birds, dipping their wings as they rose from the reeds, or how he had conceived the lacquer dragons in red gold, and the fantastic houses in the garden of peach-trees. But sooner or later the oppression of his grief returned, the loud shriek and clang of the garden-gate, the warning bell of some passing bicyclist steering through the fog, the noise of his pipe falling to the floor, would suddenly awaken him to the sense of misery. He knew that it was time to go out; he could not bear to sit still and suffer. Sometimes he cut a slice of bread and put it in his pocket, sometimes he trusted to the chance of finding a public-house, where he could have a sandwich and a glass of beer. He turned always from the main streets and lost himself in the intricate suburban byways, willing to be engulfed in the infinite whiteness of the mist.
