Fatal Accident — We learn from the Frederick Examiner, that an accident occurred on the line of the Rail road near the Monococy, on Saturday last, which resulted in the death of the individual who was its subject. A native of Ireland, named John Lanaham, was employed in carting broken stone for the horse path, from a point near the Monococy Viaduct. When the passenger car passed him in the morning, his horse took fright, and was for some time unmanageable. With assistance, however, he was kept on the track, and after some time Lanaham proceeded with his load. But the horse, still agitated by his late fright, made a sudden start, on some slight noise, and threw Lanahan, who attempted to hold him, in such a way that the wheel of the cart, heavily loaded, passed over his ancle, and severed it almost entirely from the leg. He was immediately taken to the Alms House, where amputation was resorted to, as the only means likely, or rather possible, to save his life. But it did not avail: and the unfortunate sufferer died the same night. — Balt. Pat.
