Was pulling on string ever used as a long distance method of communication? I would imagine that if you could bury a string underground in a tube for instance for long distances and then pull on that string in coded ways or in patterns (similar to morse code) you could transmit information over vast distances. I'm wondering if this was ever used throughout history pre-telegraph?
Sorry, we don't allow "example seeking" questions. It's not that your question was bad; it's that these kinds of questions tend to produce threads that are collections of disjointed, partial, inadequate responses. If you have a question about a specific historical event, period, or person, feel free to rewrite your question and submit it again. If you don't want to rewrite it, you might try submitting it to /r/history, /r/askhistory, or /r/tellmeafact.
