Okay so I have heard plenty of story's about haunted coal mines after they have closed strange noises coming out of the shafts etc.
But what happened at the Chickasaw Mine in Madison Twp. near Kittaning Pa. happened while it was still a very active mine
on March 9 of 1913 300 miners came running and screaming out of the Chickasaw Mine after a Half
Man half beast came towards them and told them to leave. It then took control of a Mine Motor and took a loaded train out of the mine but then when it came outside the beast was gone.

of course the towns people scoffed at the whole thing and papers had a field day running the news that day.
But what really happened.
There could be several things that could have caused this a mass hallucination brought on by some one bringing illegal hooch into the mine and sharing it. or lunches that where contaminated when bread in sandwich soured.
Bread back in day before preservatives has been responsible for many issues of mental illness type incidents.
Was it some one playing a big joke? or a way the miners did as a form of striking.
or maybe it was a real hallucination or divine intervention and miners where warned out before there was an explosion in the mine.
For many a miner talked about and believed in Tommy knockers little spirits that teased but also warned miners of a possible cave in.
What ever it was seems to be a one time thing the miners went back to work and mine produced coal for many years onward till it finally closed.
