None of the houses at the lower end had fallen, but several were bulging forward and appeared to be deserted. And here already the predatory instinct was at work. Linton caught the arm of a filthy-looking tramp just as he raised an iron bar to smash the plate glass window of a jeweller's shop. He hurled the thief aside, then grasping Zenobia's hand again he dragged her forward, making for the nearest bridge. But once again their way was barred. From a great crack in the roadway a fountain--a geyser--of the yellow, steaming water suddenly leaped into the air. To avoid it they were compelled to make another circuit. They hurried down some narrow streets and reached the open space in front of the theatre. Fighting their way through excited and gesticulating groups of people, they passed the hospital, and, turning to the right, reached the front of the Grand Pump Room Hotel. Limping and enfeebled invalids, who could scarcely move unaided, were streaming from the the building, appealing eagerly for guidance to a way of escape from the perils that surrounded them. Tremulous but unheeded questions were heard on every side as Linton and Zenobia crossed the road and reached the Colonnade. To their right, from the doorways of the Grand Pump Room itself, another flood of tinted steaming water was pouring rapidly over the broad pavement and stealing into the Abbey Church. By keeping close to the opposite wall they escaped the stream, and leaving the great Church, which so far seemed intact, upon their right, they soon reached the space in front of the Guildhall. Only a little distance and they would gain the bridge! "This way!" cried Zenobia, as Linton, who knew nothing of the town, stopped in hesitation. But as she spoke, the pavement, barely ten yards away, bulged suddenly, then split apart, and with a violent rush another geyser burst into the street. They drew back just in time, and hurried breathlessly towards the Station Road. On their left rose the tall building of the Empire Hotel; behind them was the Abbey. A sudden shout impelled them to look back. A third geyser had opened in the middle of the roadway, and in an instant columns of steaming water were spouting high into the air. "Quick! Quick!" urged Linton. His voice was scarcely audible, for as they approached the river a mighty roar was coming from the weir, dominating the multitudinous sounds of terror which filled the air on every side.
