A personal impression of industrial Wolverhampton by Philip Donnellan On the top of a hill in the middle of England a town of 265,000 people. The western houses drain into the Severn and the Atlantic, the eastern into the North Sea via the Trent. A split-personality town: half agriculture, half heavy industry. With a reputation for toughness, craftsmanship and colour prejudice. Right or wrong? There are 22,000 coloured immigrants in Wolverhampton now but strangers - from Ireland, Wales. France, Poland, Australia-have been flowing in for 150 years. Where are they now? (Wolverhampton, by one who didn'wander: page 13)
