"I sought for a subject, that should give equal room and freedom for description, incident, and impassioned reflections on men, nature, and society, yet supply in itself a natural connection to the parts, and unity to the whole. Such a subject I conceived myself to have found in a stream, traced from its source in the hills among the yellow-red moss and conical glass-shaped tufts of Bent, to the first break or fall, where its drops became audible, and it begins to form a channel; thence to the peat and turf barn, itself built of the same dark squares as it sheltered; to the sheepfold; to the first cultivated plot of ground; to the lonely cottage and its bleak garden won from the heath; to the hamlet, the villages, the market-town, the manufactories, and the seaport. My walks therefore were almost daily on the top of Quantock, and among its sloping coombs."
