The Pennsylvania company has been running trains every hour to the scene of the disaster or as near it as they can get. Provisions and a large volunteer relief corps have been sent up. The physicians have had an enthusiastic meeting at which one and all freely offered their services. The latest project is to have the wounded and the survivors who fled to the hillsides from the angry rush of waters brought to Pittsburgh. The Exposition Society has offered the use of its splendid new building as a temporary hospital. All the hospitals in the city have also offered to care for the sufferers free of charge to the full limit of their capacity. Word has been received at Allegheny Junction, twenty-two miles above Pittsburgh, from Leechburg that a woman and two children were seen floating past there at five o'clock yesterday morning on top of some wreckage. They were alive, and their pitiful cries for help drew the attention of the people on the shore. Some men got a boat and endeavored to reach the sufferers. As they rowed out in the stream the woman could be heard calling to them to save the children first. The men made a gallant effort. It was all without avail, as the strong current and floating masses of debris prevented them from reaching the victims, and the latter floated on down the stream until their despairing cries could no longer be heard. Mrs. Chambers, of Apollo, was swept away when her house was wrecked during the night. She had gone to bed when the flood came and she had not time to dress. Fortunately she managed to secure a hold on some wreckage which was being carried past her. She kept her hold until her cries were heard by some men a short distance above Leechburg. They got out a boat and succeeded in reaching her, and took her to a house near the bank of the river. When they got her there it was found that she was badly bruised and all her clothing had been torn off by the debris with which she had come in contact, leaving her entirely naked. She was also rescued at Natrona. A Lucky Change of Residence. Mr. F.J. Moore, of the Western Union office in this city, is giving thanks to-day for the fortunate escape of his wife and two children from the devastated city. As if by some foreknowledge of the impending disaster, Mr. Moore had arranged to have his family move yesterday from Johnstown and join him in this city. Their household goods were shipped on Thursday, and yesterday just in time to save themselves, the little party departed in the single train which made the trip between Johnstown and Pittsburgh. I called on Mrs. Moore at her husband's apartments, No. 4 Webster avenue, and found her completely prostrated by the news of the final catastrophe, coupled with the dangerous experience through which she and her little ones had passed.
