Mining Tools of the late 1800s
For that purpose, a signal code using bells was adopted in each mine. Because the signal system was one of the many mining practices that came to the States from Cornwall, the codes used by the different mines were basically the same. To ensure uniformity, however, each state eventually adopted a Code of Signals in its mining regulations.
