The Romans had long since departed, but their handiwork remained—a thin line laid like a whiplash across the broad country—a road. It extended northwestward from Frankfort and passed, as straight as might be, through the almost trackless forest that lay to the south of Moselle; for the great highway-builders had little patience with time-consuming curves; thus the road ranged over hill and down dale without shirking whatever came before it. Nearing the western terminus, it passed along high lands, through a level unbroken forest. A wayfarer, after travelling many monotonous leagues, came suddenly to an opening in the timber, and found himself on the brow of a hill, confronted with a scene amazing in extent, well calculated to arrest his progress and cause him to regard with admiration, the wide spread landscape beneath and beyond. The scene was the more startling that it burst unexpectedly on the view, after miles of trees that seemed innumerable, hemming in, with their unvarying cloak of green, the outlook of the traveller.
