Reduce Insurance Cost 

 Central Station Men! 



Fire in your plant would entail more than im* 

 mediate private loss. It would mean costly 

 interruption of an important public service as 

 well. This, and the fact that your annual insur- 

 ance premiums can be decreased from 10 to 50 

 per cent, suggest the necessity for reducing fire 

 hazard to a minimum. 



Our Engineering and Inspection 

 Service Shows You How It's Free 



Without a penny of expense to you, one of our in- 

 surance engineers will inspect your plants, recommend 

 simple methods for reducing the fire risk and we will 

 then write your insurance at the lowest possible rate for 

 the best indemnity. 



Some of the largest central stations in the country have availed 

 themselves of this expert counsel and as a result are securing theii 

 insurance at rock-bottom rates. From Montreal to Mexico City, from 

 Portland, Maine, to Portland, Oregon, we are extending this service 

 and handling insurance for public service companies. 



The first step toward getting this information as to how to safeguaid 

 your properties and cut down your premium cost is to write us TODAY.
