This is a story book. Amid that long and superb chain of the Pyrenees which forms the embattled isthmus of the peninsula, in the centre of those blue pyramids, covered in gradation with snow, forests, and downs, there opens a narrow defile, a path cut in the dried-up bed of a perpendicular torrent; it circulates among rocks, glides under bridges of frozen snow, twines along the edges of inundated precipices to scale the adjacent mountains of Urdoz and Oleron, and at last rising over their unequal ridges, turns their nebulous peak into a new country which has also its mountains and its depths, and, quitting France, descends into Spain. Never has the hoof of the mule left its trace in these windings; man himself can with difficulty stand upright there, even with the hempen boots which can not slip, and the hook of the pikestaff to force into the crevices of the rocks.
