Deep in the hollow the Exe winds and bends, finding a crooked way among the ruddy rocks. Sometimes an almost inaccessible precipice rises on one shore, covered with firs and ferns, which no one can gather; while on the other is a narrow but verdant strip of mead. Coming down in flood from the moors the Exe will not wait to run round its curves, but rushes across the intervening corner, and leaves behind, as it subsides, a mass of stones, fiat as slates or scales, destroying the grass.
