Final answer:
In literature, 'medium' refers to how a story is delivered to the reader. 'The Interlopers' is a short story where the 'fallen trees' play a role in the narrative, serving as both a physical barrier and a symbolic element.
The term 'medium' has different meanings in different contexts, such as spiritualism in the case of the 'Long Island Medium'.
Step-by-step explanation:
The term 'medium' in the context of your question refers to the method or material through which artistic expression is conveyed or the way a message is delivered in a story. In literature, it might refer to the actual physical book or text itself, the narrative structure, or any other form used by the author to transmit their story to the reader.
However, if you are asking about a specific piece of literature titled 'The Interlopers' and the role of 'the fallen trees', it sounds like you might be referring to elements of the story itself. 'The Interlopers' is a short story by Saki (H. H. Munro), and in this story, the fallen trees would be part of the setting that directly impacts the plot.
They represent a physical barrier that traps the characters, but symbolically, they may also reflect the barriers between the feuding families in the story. As for mediums in the sense of communicating with the dead, such as references to the 'Long Island Medium' on Ellen DeGeneres show, that is related to the belief in spiritualism and the paranormal, which is a separate concept from literary mediums.
