New Method of Protecting Property 

 from Lightning. 



Price, $20 to $30— According to size. 



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 of a lightning discharge, — to prevent its 

 doing harm, — placing something in its path 

 upon which its capacity for causing damage 

 may be expended. 



No recorded case of lightning stroke has 

 yet been cited against the principle of the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed. 



Correspondence solicited.
