William Zebina Ripley, Railroads: Rates and Regulations
“ Yet the enhancement of railway revenues would indeed be enormous from such an increase of freight rates. For these necessities of life, an increased freight rate might become an actual charge upon the people, without reducing their consumption, like a tax upon salt. Only upon goods the use of which might be freely lessened, would higher freight rates be reflected in a corresponding decline in the volume of business. Moreover, with all high grade traffic, the value of service principle fails utterly by itself alone to prescribe the upper level of a reasonable charge. ”
