The annual Heritage Open Day, in the middle of last month, and the only property advertising free entry in Wolverhampton was Moseley Old hall, and that only on the Saturday. Wandering round the garden, I noticed a line of pear trees against one wall of the house. All the leaves seemed to be heavily infested with pear rust. There were multiple powdery-looking dull orange raised patches on the underside of each leaf, each corresponding with a brighter orange mark above.
