He was conductor on the fast express between these two parts and during his duties as such, slipped and fell off the train, striking on his head. The skull was terribly crushed. The man lived a few hours, but never regained consciousness. The remains were taken to his sister, Ida's, Kalispell, Montana and interred in the cemetery there. Deceased was a native of this city, being a s/o late Joseph ROSBOROUGH, tanner. He left here when a young man and has resided in the west ever since. A number of his sisters also reside in the west.
