Another eye-witness describes the calamity as follows: A flood of death swept down the Alleghany Mountains yesterday afternoon and last night. Almost the entire city of Johnstown is swimming about in the rushing, angry tide. Dead bodies are floating about in every direction, and almost every piece of movable timber is carrying from the doomed city a corpse of humanity, drifting with the raging waters. The disaster overtook Johnstown about six o'clock last evening. As the train bearing the writer sped eastward, the reports at each stop grew more appalling. At Derry a group of railway officials were gathered who had come from Bolivar, the end of the passable portion of the road westward. They had seen but a small portion of the awful flood, but enough to allow them to imagine the rest. Down through the Packsaddle came the rushing waters. The wooded heights of the Alleghanies looked down in wonder at the scene of the most terrible destruction that ever struck the romantic valley of the Conemaugh. The water was rising when the men left at six o'clock at the rate of five feet an hour. Clinging to improvised rafts, constructed in the death battle from floating boards and timbers, were agonized men, women and children, their heartrending shrieks for help striking horror to the breasts of the onlookers. Their cries were of no avail. Carried along at railway speed on the breast of this rushing torrent, no human ingenuity could devise a means of rescue. With pallid face and hair clinging wet and damp to her cheek, a mother was seen grasping a floating timber, while on her other arm she held her babe, already drowned. With a death-grip on a plank a strong man just giving up hope cast an imploring look to those on the bank, and an instant later he had sunk into the waves. Prayers to God and cries to those in safety rang above the roaring waves. The special train pulled into Bolivar at half-past eleven last night, and the trainmen were there notified that further progress was impossible. The greatest excitement prevailed at this place, and parties of citizens are out all the time endeavoring to save the poor unfortunates that are being hurled to eternity on the rushing torrent. Attempts at Rescue. The tidal wave struck Bolivar just after dark, and in five minutes the Conemaugh rose from six to forty feet and the waters spread out over the whole country. Soon houses began floating down, and clinging to the debris were men, women and children shrieking for aid. A large number of citizens at once gathered on the county bridge, and they were reinforced by a number from Garfield, a town on the opposite side of the river.
