Having given this alarm. Keith, Johnny at his elbow, started toward the centre of disturbance, From it arose a dull, menacing roar, like the sound of breakers on a rocky coast. Many people, with much excitement, shouting, and vituperation, were converging toward the common centre. As this was approached, it became more difficult, at last impossible, to proceed. The streets were packed, jammed. All sorts of rumours were abroad--King, was dead--King was only slightly hurt--Casey was not in jail at all--Casey had escaped down the Peninsula--the United States warships had anchored off the foot of Market Street and were preparing to bombard the city. There was much rushing to and fro without cause. And over all the roar could be distinguished occasionally single cries, as one may catch fragments of conversation in a crowded room, and all of these were sinister: "Hang him!" "Where is he?" "Run him up on a lamp post!" "Bring him out!" "He'll get away if left to the officers!" And over all the cries, the shouts, the curses, the noise of shuffling feet, the very sound of heavy breathing--that--the numbers of the mob magnified to a muffled, formidable undernote, pealed louder and louder the Monumental bell, which now Bert Taylor--or some one else--was ringing like mad. Keith's eyes had become grim and inscrutable, and his mouth had settled into a hard, straight line. Johnny's interest had at first centred in the mob, but after a few curious glances at his companion he transferred it entirely to him, Johnny Fairfax was a judge of men and of crises; and now he was invaded with a great curiosity to see how the one and the other were here to work out. With a determination that would not be gainsaid, Keith thrust himself through the crowd until he had gained an elevated coping. Here he stood watching. Johnny, after a glance at his face, joined him. Suddenly in the entrance of Dunbar Alley, next the city jail, a compact group of men with drawn pistols appeared. They made their way rapidly to a carriage standing near, jumped in, and the driver whipped up his horses. With a yell of rage the crowd charged down, but recoiled instinctively before the presented pistols. The horses reared and plunged, and before anybody had gathered his wits sufficiently to seize the bridles, the whole equipage had disappeared around the corner of Kearney Street. "I must say that was well done," said Johnny. "North and Charles Duane, with Casey, inside," commented Keith, as dispassionately as though reading from a catalogue. "Billy Mulligan and his deputies outside. That is to be remembered." A great mob had surged after the disappearing vehicle, but at least fifty yards in the rear. The remainder were following at a more leisurely pace. Almost immediately the street was empty. Keith climbed slowly down from his coping. "What do you intend doing?" asked Johnny curiously. "Nothing yet." "But they're getting him away!"
