Answer:
The feud between Georg and Ulrich is about the forestland between the two families.
Step-by-step explanation:
Saki's short story "The Interlopers" revolves around two neighboring families who claimed ownership over a forested land. The story delves into themes of rivalry, reconciliation, hate, evil, etc.
The two neighbors Ulrich von Gradwitz and Georg Znaeym had always been at odds about a forested land in between their properties which they claimed belong to them. While Georg claimed that the courts had unfairly judged in favor of Ulrich's family in their grandfathers' times, the feud continues to their generations so much that it developed into personal hatred.
