Force-fire
Force-fire was a Scottish folklore tradition believed to have the ability to rid houses of evil spirits.
Force-fire was a relatively common folklore activity in Scotland up until the 19th century, or the Highland Clearances to be precise. Believers of the force-fire said that it was a viable and effective treatment to the plague on humans, diseases in cattle, murrain and bewitching. Needles to say, there is no scientific evidence supporting the practice of the force-fire.
The procedure of the force-fire varied by region, but the general element remained constant. When a community deemed it necessary to perform a force, all the fires in that area were extinguished on a set day. Following this, a new fire was relit and distributed to all those affected by the ailment of the community, be it disease or witchcraft. Anecdotally, this was met with great success and the appropriate households were soon rid of their problems.
The method by which a force-fire was started is the biggest difference between any sets of practioning areas. Some documented cases record that a group of 81 men would be scheduled into shifts to rub two large pieces of wood together, subsequently, the friction of the activity would eventually light the wood on fire. Other regions use a spinning wheel would be spun and fed with kindling, until the spindle caught on fire. In each case more wood would be lit and the fire distributed to households.
The last recorded cases of force-fire were in 1829 in North Uist and 1830 in Reay.
