“The river, reflecting the clear blue of the sky, glistened and sparkled as it flowed noiselessly on.”There was no moon, and everything beneath lay in misty darkness: not a light gleamed from any house, far or near all had been extinguished long ago: and those at Wuthering Heights were never visible…“Gimmerton chapel bells were still ringing; and the full, mellow flow of the beck in the valley came soothingly on the ear. It was a sweet substitute for the yet absent murmur of the summer foliage, which drowned that music about the Grange when the trees were in leaf.”
