A short distance east of the tunnel — a reminder of the Portage — the road-bed was annihilated, compelling an ascent by a rough path to the de serted line on the wooded hillside.  Walking through the dripping tunnel, which rarely echoes the tread of human feet, and down the slope that once served as an incline up which cars were drawn by a stationary engine, Penn sylvania railroad bridge No.  6 was missing.
