This warm Christmas season isn’t conducive to fires in the fireplace or bumping up the thermostat to keep the house comfortable. That wasn’t the case in the winter of 1919 as a strike by miners threatened supplies of coal used to heat homes and businesses and generate electricity to keep factories running, streets and residences lighted. The strike began in November and became so serious that the federal government’s Fuel Administration imposed regulations that put a dent in normal activities during the busy holiday season.
