I want to know the answer to the following question:
What did the group at the Bells house hear other people doing?
All the background I'm provided with is that "The following night, he amazed guests as well as his family when a message was received at the Bell home from Brantford, four miles (six km) distant, along an improvised wire strung up along telegraph lines and fences, and laid through a tunnel.". Is that enough to answer the question?
Answer: no
