As I walked down at this place I was walled on both sides by those inaccessible high rocky barren hills which hang over one’s head in some places and appear very terrible; and from them springs many little currents of water from the sides and clefts which trickle down to some lower part where it runs swiftly over the stones and shelves in the way, which makes a pleasant rush and murmuring noise and like a snowball is increased by each spring trickling down on either side of those hills, and so descends into the bottoms which are a Moorish ground in which in many places the waters stand, and so form some of those Lakes as it did here.
