THE PLOTTING 103 



The gain in uniformity with each successive step as compared 

 with the preceding one is noteworthy, but the procedure of a 

 service charge is much better than any of the others and is as 

 simple and easy as any in application. 



It may not be amiss to repeat for emphasis that for normal 

 conditions equal revenue will be obtained from all domestic 

 takers by these rates: 



(a) A rate of 29 cents per 1000 gallons, with no minimum. 



(b) A rate of 26 cents per 1000 gallons, with an $8 minimum. 



(c) A rate of 20 cents per 1000 gallons, with a $5 service 

 charge. 



Similar differences will be found for other ordinary rates.
