AFTER a gentle descent I entered on an extreme stony narrow vale, through which coasted swiftly a large creek, twelve or fifteen yards wide, roaring over a rocky bed, which I crossed with difficulty and danger; the ford being incommoded by shelving rocks, full of holes and cliffs; after leaving this rocky creek my path led me upon another narrow vale or glade, down which came in great haste another noisy brook, which I repeatedly crossed and recrossed, sometimes riding on narrow level grassy verges close to its banks, still ascending, the vale gradually terminated, being shut up by stupendous rocky hills on each side, leaving a very narrow gap or defile.
