The South Fork Reservoir was the largest in the United States, and it contained millions of tons of water. When its fetters were loosened, crumbling before it like sand, a building or even a rock that stood in its path presented as much resistance as a card house. The dread execution was little more than the work of an instant. The flood passed over the town as it would over a pile of shingles, covering over or carrying with it everything that stood in its way. It bounded down the valley, wreaking destruction and death on each hand and in its fore. Torrents that poured down out of the wilds of the mountains swelled its volume. All along from the point of its release it bore debris and corpses as its hideous trophies. In a very brief time it displayed some of both, as if in hellish glee, to the horrified eyes of Pittsburg, seventy-eight miles west of the town of Johnstown that had been, having danced them along on its exultant billows or rolled them over and over in the depths of its dark current all the way through the Conemaugh, the Kiskiminitas and the Allegheny river. It was like a fearful monster, gnashing its dripping jaws in the scared face of the multitude, in the flesh of its victims. One eye-witness of the effects of the deluge declares that he saw five hundred dead bodies. Hundreds were counted by others. It will take many a day to make up the death roll. It will take many a day to make up the reckoning of the material loss. If any pen could describe the scenes of terror, anguish and destruction which have taken place in Conemaugh Valley it could write an epic greater than the "Iliad." The accounts that come tell of hairbreadth escapes, heartrending tragedies and deeds of heroism almost without number. A Climax of Horror. As if to add a lurid touch of horror to the picture that might surpass all the rest a conflagration came to mock those who were in fear of drowning with a death yet more terrible. Where the ruins of Johnstown, composed mainly of timber, had been piled up forty feet high against a railroad bridge below the town a fire was started and raged with eager fury. It is said that scores of persons were burned alive, their piercing cries appealing for aid to hundreds of spectators who stood on the banks of the river, but could do nothing. Western Pennsylvania is in mourning. Business in the cities is virtually suspended and all minds are bent upon this great horror, all hearts convulsed with the common sorrow. Heartrending Scenes and Heroic Struggles for Life.
