Read it through once

The bird’s-eye perspective before her was not so luxuriantly beautiful, perhaps, as that other one which she knew so well; yet it was more cheering. It lacked the intensely blue atmosphere of the rival vale, and its heavy soils and scents; the new air was clear, bracing, ethereal. The river itself, which nourished the grass and cows of these renowned dairies, flowed not like the streams in Blackmoor. Those were slow, silent, often turbid; flowing over beds of mud into which the incautious wader might sink and vanish unawares. The Froom waters were clear as the pure River of Life shown to the Evangelist, rapid as the shadow of a cloud, with pebbly shallows that prattled to the sky all day long. There the water-flower was the lily; the crow-foot here.
