Telegraph wire splicing
I am doing some research for a historical novel about the transcontinental railroad. I am wondering how telegraph wires were spliced in the mid nineteenth century? If solder was used, how was it applied? I have found some reference to a gas powered solder melting pot, but I don't know if that was used on wires. If a soldering iron was used, how was it heated? Was any kind of tape used? Does anyone know? ...
