To send a telegram you had to hand deliver your message to a telegraph office. There, an operator enters the message into a telegraph, which then translates it into Morse code and routes it to its destination. At the receiving end, machines translate the encoded message back into words and print it out. The telegraph office hand delivers the message to the person receiving it.

Western movies don't tell you that.
