" It shall so confine its current to the metallic return 

 circuit so as to comply with the following conditions : 



" The maximum difference is potential between any part 

 of the metallic return circuit and any water or service pipe or 

 other metal conductor not intended as a part of such return 

 circuit, shall not at any time exceed ^ volt. 



"The difference in potential between any two points 

 upon said metallic return circuit within a distance of 200 feet 

 from each other, shall not, at any time, exceed J^ volt. 



" The current passing along any water or service pipe or 

 other metallic conductor not intended as a part of said return 

 circuit, shall not at any given time and point exceed one 

 ampere. 



" Tests shall be made during two months of the yeai, 

 February and August, for the purpose of detecting stray 

 currents, by the city electrician or other competent person. 

 If any such damage is found to be done to the water pipes or 

 gas pipes, then the company is held responsible and has to 

 pay the cost both of discovery and repairing. 



" Penalty $50.00 to $100.00 a day." 



In conclusion I have to state that owing to my having 

 been so very much occupied of late, I have hardly been able 

 to do justice to this subject, but I trust that sufficient has 

 been said to demonstrate the importance of it, and I do hope 

 that the brief account has not been entirely unacceptable to 

 the members of your association.
