It was pierced by two windows. One of them was invisible, hidden by a partition which could, however, be lowered by a spring so as to permit fresh air to circulate around this pinewood box and to penetrate into it. The other was visible, placed directly opposite the porthole built in the wainscoting, but it was blocked up. For a long aquarium occupied the entire space between the porthole and the genuine window placed in the outer wall. Thus the light, in order to brighten the room, traversed the window, whose panes had been replaced by a plate glass, the water, and, lastly, the window of the porthole. In autumn, at sunset, when the steam rose from the samovar on the table, the water of the aquarium, wan and glassy all during the morning, reddened like blazing gleams of embers and lapped restlessly against the light-colored wood. Sometimes, when it chanced that Des Esseintes was awake in the afternoon, he operated the stops of the pipes and conduits which emptied the aquarium, replacing it with pure water. Into this, he poured drops of colored liquids that made it green or brackish, opaline or silvery--tones similar to those of rivers which reflect the color of the sky, the intensity of the sun, the menace of rain--which reflect, in a word, the state of the season and atmosphere. When he did this, he imagined himself on a brig, between decks, and curiously he contemplated the marvelous, mechanical fish, wound like clocks, which passed before the porthole or clung to the artificial sea-weed. While he inhaled the odor of tar, introduced into the room shortly before his arrival, he examined colored engravings, hung on the walls, which represented, just as at Lloyd's office and the steamship agencies, steamers bound for Valparaiso and La Platte, and looked at framed pictures on which were inscribed the itineraries of the Royal Mail Steam Packet, the Lopez and the Valery Companies, the freight and port calls of the Atlantic mail boats. If he tired of consulting these guides, he could rest his eyes by gazing at the chronometers and sea compasses, the sextants, field glasses and cards strewn on a table on which stood a single volume, bound in sealskin. The book was "The Adventures of Arthur Gordon Pym", specially printed for him on laid paper, each sheet carefully selected, with a sea-gull watermark. Or, he could look at fishing rods, tan-colored nets, rolls of russet sail, a tiny, black-painted cork anchor--all thrown in a heap near the door communicating with the kitchen by a passage furnished with cappadine silk which reabsorbed, just as in the corridor which connected the dining room with his study, every odor and sound.
