The Rural Voice, 2001-05, Page 30A striking collector's item What do farmers and ornament collectors have in common — would you believe the lightning rod! For over 100 years, lightning rods have stood guard over many Ontario farm buildings, ready to take that next lightning strike. But for almost as long as lightning rods have been around, these guardians have also been adorned — even if not always adored. Installations of lightning rods took off in the late 1800s when salesmen scoured the countryside to convince farmers that they were in need of lightning protection. While the protection offered by a properly installed system is not disputed, some unscrupulous salesmen in the early 1900s started to taint the lightning rod's image. For example, one old story tells of a salesman saving on the expense of installing the heavy copper cables by substituting rope that was disguised by pale green paint — a trick not readily noticeable high up on a barn roof. As the salesman was long -gone when an improperly installed system failed or was discovered, the humble lightning rod took the blame. By the 1920s, concerns over Installers must be licensed Installers are licensed with the Ontario Fire Marshal's office, which is also responsible for inspecting installations.

Photo and story by Larry Drew This lightning rod and the white milk -glass ball date from the early 1920s. It still stands on the pump house at the author's family farm. improper installations resulted in the passage of the Lightning Rods Act that requires certified installers and an inspection from the Fire Marshal's office. The early salesmen also sold farmers glass "insulators" to place on their lightning rods. But according to the experts these balls were meant entirely for decoration, and simply served no other purpose. While some farmers may have wanted to decorate their barns with ornaments, some obviously were convinced that the "insulators" were a necessity — a belief that is still held by some today. Joyce Blyth, a collector who has bought old and interesting glass balls from farmers, learned to carry a box of white ceramic or modern plastic balls on her travels. That's because some potential sellers balked at a sale — including some who insisted the rods wouldn't work without them — unless she was able to install new So, what are the odds of being struck by lightning? Lightning strikes every square mile of Ontario an average of 15 to 20 times per year. A single storm traversing Central Ontario may record over 2500 lightning strikes in just a few hours time. Lightning may strike twice — to say the least. The CN Tower may take 20 strikes in a single storm. The lightning rods don't attract the lightning, but rather are placed where lightning is most likely to strike. Because rods don't attract lightning from a distance, installation requires multiple rods based on the area of the rooftop. If lightning is going to strike, it's better to hit a rod and be properly grounded rather than strike the structure or something nearby where it could cause serious damage. Tin siding or T.V. antennas are NOT designed to take and ground lightning strikes — strikes that may have over 10 million volts and create temperatures of 30,000 degrees Celsius.0
