The crowd on the sidewalk gave way before the deeply incensed and resolute officers of the law. Merwyn, with a half-dozen others, seized a heavy pole which had been cut down in order to destroy telegraphic communication, and, using it as a ram, crashed in the door of a tall tenement-house on the roof of which were a score of rioters, meantime escaping their missiles as by a miracle. Rushing in, paying no heed to protests, and clubbing those who resisted, he kept pace with the foremost. In his left hand, however, he carried his trusty revolver, for he did not propose to be assassinated by skulkers in the dark passage-ways. Seeing a man levelling a gun from a dusky corner, he fired instantly, and man and gun dropped. As the guardians of the law approached the scuttle, having fought their way thither, the ruffians stood ready to hurl down bricks, torn from the chimneys; but two or three well-aimed shots cleared the way, and the policemen were on the roof, bringing down a man with every blow. One brawny fellow rushed upon Merwyn, but received such a stroke on his temple that he fell, rolled off the roof, and struck the pavement, a crushed and shapeless mass. The assaults upon the other houses were equally successful, but the fight was a severe one, and was maintained for nearly an hour. The mob was appalled by the fate of their friends, and looked on in sullen, impotent anger. Having cleared the houses, the police re-formed in the street, and marched away to other turbulent districts. Only the military were left, and had formed about a block further to the north. Beyond the feeble demonstration of the invalid corps the rioters, as yet, had had no experience with the soldiery. That policemen would use their clubs was to them a matter of course, but they scarcely believed that cannon and musketry would be employed. Moreover, they were maddened and reckless that so many of their best and bravest had been put hors de combat. The brief paralysis caused by the remorseless clubs of the police passed, and like a sluggish monster, the mob, aroused to sudden fury, pressed upon the soldiery, hurling not only the vilest epithets but every missile on which they could lay their hands. Colonel O'Brien, in command for the moment, rode through the crowd, supposing he could overawe them by his fearless bearing; but they only scoffed at him, and the attack upon his men grew more bold and reckless. The limit of patience was passed. "Fire!" he thundered, and the howitzers poured their deadly canister point-blank into the throng. At the same time the soldiers discharged their muskets. Not only men, but women fell on every side, one with a child in her arms.
