Lightning Protection
Excerpt from Lightning Protection
It has been conclusively shown by means of statistics secured1 in other states that buildings provided with good lightning rods actually decrease the number of strokes which occur. This is in accord With the theory of the lightning discharge. Professor Day found in the province of Ontario that out of every unrodded farm buildings, 37 were struck, while but two rodded buildings were struck in structures thus protected. This represents an efficiency of 94 per cent. For the lightning rod. During the following year an efficiency of 92 per cent. Was recorded, while in Iowa an average efficiency of 98 per cent. Was maintained from 1905 to 1912. In short, lightning rods may be justly considered as a legitimate form of preventive insurance.
