In autumn, George goes underground, digging below an oak tree to see how its roots extract precious resources from the soil. And he sees why the oak's superstrong wood made it the perfect material for building some the most famous ships in naval history, including Nelson's flagship The Victory. In winter, George discovers the sophisticated strategies the tree uses to survive gales and bitter frosts. He finds out about the oak's vital role in architecture, showing how some very familiar sights, such as the tower of Salisbury Cathedral, are in fact giant oak structures.
