amount of trouble and expense; 4 Nev, & M. 7; 4 С. В. N. S. 366; but a contrary view prevails in the United States; 12 Fed. Rep. 309; 31 Fed. Rep. 652; 43 Ohio St. 379; 1 Interst. Com. Rep. 107; and in any case it is not lawful to charge a less rate to all the inhabitants of one town, irrespective of their individual shipments, than to those of another, though the aggregate of freight shipped by the former is greater than that shipped by the latter; 4 Eng. R. R. & Canal Traffic Cases 291. The rule requiring equal charges for equal distances does not require that the rates for a specified distance should be increased for every greater distance by the corresponding multiple of the specified distance; 111 E. С. L. 248; 1 Interst. Com. Rep. 480; 74 Pa. 190. Under the Interstate Commerce Act.- This question of discrimination arises in the United States most frequently under the provisions of the Interstate Commerce Act of 1887, Feb. 24; U. S. Rev. Stat. 1 Supp. 529, which provides: (§ 2) That if any com- mon carrier subject to the provisions of this act shall, directly or indirectly, by any spe- cial rate, rebate, drawback, or other device, charge, demand, collect, or receive from any person or persons a greater or less com- pensation for any service rendered, or to be rendered, in the transportation of passen- gers or property, subject to the provisions of this act, than it charges, demands, col- lects, or receives from any other person or persons for doing for him or them a like and contemporaneous service in the transporta- tion of a like kind of traffic under substan- tially similar circumstances and conditions, such common carrier shall be deemed guilty of unjust discrimination; (§3) That it shall be unlawful for any such common carrier to give any undue or unreasonable prefer- ence or advantage to any particular person, company, firm, corporation, or locality, or description of traffic, or subject such to any undue or unreasonable prejudice or disad- vantage; and (§ 4) That it shall be unlaw- ful for any such common carrier to charge or receive any greater compensation in the aggregate for the transportation of passen- gers or of like kind of property, under sub- stantially similar circumstances and condi- tions, for a shorter than for a longer dis- tance, within the same line in the same direction, the shorter being included in the longer distance. The fact that one railroad is long and circuitous, and therefore obliged to charge a less rate per mile to a competitive point than its shorter rivals, will not establish dissimilar conditions, nor does the fact that there is possible water competition; 1 In- terst. Com. Rep. 160; but differences in grade compelling the use of shorter trains, is to be considered in deciding the question of discriminations; 4 Nev. & Μ. 192. So, it would seem that an increase in the speed of trains will justify an increase in the rate of freight charged; 4 Eng. R. R. & Canal Traffic Cases 291; as may the fact that cars are of a peculiar construction, and only fit for hauling a certain class of freight, so that they must be returned empty; but not the fact that cars are of an improved construc- tion, so that more valuable freight is trans- ported in them; 1 Interst. Com. Rep. 182. On the other hand, it is not discrimination for a carrier to refuse to transport cattle in cars of a special construction furnished by the shipper, when it supplies cars for the same purpose, which it can use more con- veniently and profitably by reason of their being likewise so adapted for other freight when not used for carrying cattle; 6 Ry. & Corp. L. J. 364. The doing for or allowing to one party or place what is denied to another. 17 A. & E. Ency. 2nd ed.. 143. In interstate commerce, unjust discrimi- nations by carriers between persons, cor- porations, or localities, either in rates or facilities, in the rendition of like services under similar conditions and circumstances, is deemed unlawful by the Interstate Com- merce Act.
