The brook is transformed into an inky drain, foul with the smell of bleach-works, but Whitethroat and Sedge-Warbler still nest amongst the briars and brambles which overhang it. The quiet field-pond in the hollow becomes the rubbishtip of neighbouring back-yards, but, as long as it has its fringe of willow and a few tufts of sedge and rushes, the Reed Bunting still makes it his home.
