LIGHTNING-KODS. 



Based upon this theory, there has recently been advanced 

 an idea that seems sensible. It is to substitute a piece of 

 galvanized telegraph wire for the kite-string, a pointed rod 

 of iron at the top of the building for the kite, and another 

 rod driven into the ground for the key in Dr. Franklin's 

 hand. 



The iron at the top should project five or six feet above 

 the roof, and if the ridge-pole is more than twenty feet 

 long, there should be two or more of these, all to be con- 

 nected with each other and with the rod in the ground by 

 simple wire. 



This plan has the great merit of being cheap and within 

 the reach of all and, so far as anything is actually known 

 of the subject, is as good as the more elaborate and expen- 

 sive ones.
