Through the dust they saw one another as ghosts, staggering, helpless, dodging toppling shapes. They shouted across the chaos and only knew the other had cried by the sight of the opened mouth. All sounds were drowned in the surrounding tumult, the roar of the shaken city and the _temblor's_ thunderous mutter. Rafters, crushed together, then strained apart, creaked and groaned and crunched. Walls receded with a reeling swing and advanced with a crackling rush. The paper split into shreds; the plaster skin beneath ripped open; lathes broke in splintered ends; mortar came thudding from above and swept in a swirling drive about their feet. He shouted to her and made a run for the door. Hanging to the knob he was thrown from side to side by the paroxysmal leaps of the building. The door jammed, and, his wrenchings futile, he turned and dashed to the window. Here again the sash stuck. He kicked it, frantic, caught a glimpse of the street, people in nightgowns, a chimney swaying and then falling in a long drooping sweep. Somewhere beyond it a high building shook off its cornices like a terrier shaking water from its hair. Grinding his teeth, cursing, he wrenched at the window, tore at the clasp, then turned in desperation and saw the door, loosed by a sudden throe, swing open. Through reeling dust clouds Pancha darted for it, her flight like the swoop of a bird, and he followed, running crazily along the heaving floor. The hall was fog-thick with powdered mortar, and careening like a ship in a gale. He had an impression of walls zigzagged with cracks, of furniture, upturned, making dives across the passage. White figures were all about; some ran, some stood in doorways and all were silent. He thrust a woman out of his way and felt her move, acquiescingly, as if indifferent. Another, a child in her arms, clawed at his back, forced him aside, and as she sped by he saw the child's face over her shoulder, placid and sweet, and caught her voice in a moaning wail, "Oh, my baby! Oh, my baby!" A man, holding the hand of a girl, was thrown against the wall and dropped, the girl tugging at him, trying to drag him to his feet. Something, with blood on its whiteness, lay huddled across the sill of an open doorway. Pancha was ahead of him, a long narrow shape that he could just discern. A length of ceiling fell between them, a sofa, like a thing endowed with malign life, rushed from the wall and blocked his passage. He scrambled over it and saw the stair head, and a clearer light. That meant deliverance--the street one flight below. The floor sagged and cracked, he could feel it going, and with a screaming leap he threw himself at the balustrade, caught and clung. From above he heard a cry, "Up, up, not down!" had a vision of Pancha on the second flight, flying upward, and himself plunged downward to the street.
