English wildness existed in the main as Nash's 'unseen landscapes': it was there, if carefully looked for, in a bend of a stream valley, in the undercut of a river bank, in copses and peat hags, hedgerows and quicksand pools. And it was there in the margins, interzones and rough cusps of the country; quarry rim, derelict factory and motorway verge.
