Omaha, Aug. 22.- Union Paoiflc train No. 8, whioh waa held up by express robberg threo miles east of Brady's Island, pulled into Omaha two hours and ten minutes late. If the nows of the oocurrence had not preceded lt the appearanoe of the express car was sufficlent to show that sumething unusual had occurred. The dynamlte explosión had blown all the windows from the car and through the openings could be the seen shattered interior. The floor was littered with bits of glasg and splinters and the safes, trunks and other artioles all bore avidenoe of the tretnendous foroe of the explosión. Ü2Í The big safe at one ilde on whioh the dynamlte had been piled was badly mangled. The top waa oraoked in sevoral dlrectiona and one big rent near the center indicated the spot where the explosiva had been plaoed. The force of the explosión, however, was not luffioiant to afford acouas to the interior. iCxpress Messenger Thomas MoCarl was engaged in making up hls report. Aooordlng to his statement the robbers did not get over $100 for thelr trouble. They had aacked the way safe, bul failed to get inslde of the largo safe whioh oontalned the most valuable paokages. Conductor Flynn says that the robbers nndoubtedly boarded the train at Brady's Island. They lald low until the train reached the seconcl curve in the sand hl lis, when they climbed over the tender and levelled their revolvers at the engineet and lireman and compelled them to stop the train. Then they ordered the engineer to out the train behlnd the express oar, but he pretended that he could not undo the coupling, and this was abandoned. Then they took him to the north door of the express car and ordered him to oall to the messenger to open the door. The engineer told the messenger that they carrled Winchesters and would blow the top of his hoad off uuless the door was opened. Conductor Flynn thinks that the escape of the ñreman wlth the engine alarrued the robbara and oaused them to leave before they had oompleted their work. The horses of the robbers have been captured, and lt is balieved here that the bandits are surrounded. Forty wellarmed men are in pursuit, and a flght is expected.
