Harold Hamilton, Isaac Walker, J. M. Bear and Wingfield Enochs, Americans, outside laborers, were electrocuted at
Procktor Mine of the Procktor Coal Company. These men, together with three others, were changing the electric wires
from a temporary substation to a permanent rotary substation which had just been completed.
In stretching the necessary connecting wires they allowed the line to swing to such an extent that
it came in contact with the high voltage wires of the Logan County Light and
Power Company, carrying 11,000 volts, killing four instantly and badly burning the
others. Source document.
