The wells have run dry again . On yesterdays walk I see that the old farmer has rigged up an ancient tractor and pump to bring the water to the surface from the aquifer deep below . Unsightly but effective . Waste not want not the local farmers creed . Wilf is far too busy rooting out unmentionable things in the long grass to bother about the tractor . He finds, and happily displays, an old bone . As he knows " one cannot refuse to eat just because there is a chance of being choked ".
