Twilight draws on, the summons of Isabel is heard from the door; the poor, frozen, blue-lipped, soul-shivering traveler for St. Petersburg is unpacked; and for a moment stands toddling on the floor. Then his hat, and his cane, and out he sallies for fresh air. A most comfortless staggering of a stroll! People gaze at him passing, as at some imprudent sick man, willfully burst from his bed. If an acquaintance is met, and would say a pleasant newsmonger's word in his ear, that acquaintance turns from him, affronted at his hard aspect of icy discourtesy. "Bad-hearted," mutters the man, and goes on. He comes back to his chambers, and sits down at the neat table of Delly; and Isabel soothingly eyes him, and presses him to eat and be strong. But his is the famishing which loathes all food. He can not eat but by force. He has assassinated the natural day; how then can he eat with an appetite? If he lays him down, he can not sleep; he has waked the infinite wakefulness in him; then how can he slumber? Still his book, like a vast lumbering planet, revolves in his aching head. He can not command the thing out of its orbit; fain would he behead himself, to gain one night's repose. At last the heavy hours move on; and sheer exhaustion overtakes him, and he lies still--not asleep as children and day-laborers sleep--but he lies still from his throbbings, and for that interval holdingly sheaths the beak of the vulture in his hand, and lets it not enter his heart. Morning comes; again the dropt sash, the icy water, the flesh-brush, the breakfast, the hot bricks, the ink, the pen, the from-eight-o'clock-to-half-past-four, and the whole general inclusive hell of the same departed day. Ah! shivering thus day after day in his wrappers and cloaks, is this the warm lad that once sung to the world of the Tropical Summer? BOOK XXIII. A LETTER FOR PIERRE. ISABEL.
