Mr Knights taught us geography at secondary school. Then it was thought important to know about cotton in Lancashire, coal in South Wales and shipbuilding on the Clyde. We learned to read Ordnance Survey maps and looked for arêtes, u-shaped valleys and ox-bow lakes. Deserts came to life with barchans, linear and sief dunes. He offered us curiosity about the world.
