This is a bill in equity, originally brought by Wilbur Boyle as a stockholder in the railroad company, now one of the appellees, to prevent it from paying, and the Railroad Commission of Arkansas from enforcing, freight rates established by the latter, and a 2-cent passenger rate fixed by a statute of 1907, on the ground that both were confiscatory. A temporary injunction was issued, freight rates were adopted higher than those established by the State Commission, and the 3-cent passenger rate previously in force was restored, a bond being given for keeping accounts and refunding the difference if the final decision should uphold the action of the state. Later by agreement the experiment of a 2 1/2-cent passenger rate was tried for eighteen months, and the final hearing of the cause was postponed to await the decision of Allen v. St. Louis, I. M. & S. R. Co. 230 U. S. 553, 57 L. ed. 1625, 33 Sup. Ct. Rep. 1030, in which the same rates were before the court. That decision was rendered on June 16, 1913, and forthwith after that and the others reported in 230 U. S., there was a conference of railroad managers and officials, engineers and others competent to aid, for the purpose of devising formulas for the division of expenses, etc., between local and interstate business in accord with the views of this court, as a step toward determining the constitutionality of this and other rates sought to be imposed by the states. The railroad company then made a laborious attempt to apply the formulas thus reached, and, as a result, the injunction was made perpetual, subject to a change of circumstances, after a careful discussion by the district court. P.U.R. 1916A, 49, 222 Fed. 539.

The value of the railroad property for the years 1910-1913 was admitted. The question in dispute is the usual one of the division of expense and income between state and interstate business. The decision below explains in greater detail than it is necessary to repeat the method of investigation adopted by the railroad. For the months of November and December, 1913, it caused the most minute and specific reports to be made of all the facts that, by the formulas prepared, would throw light upon the problem to be solved. Such an investigation is too expensive to be kept up for more than a limited time, but evidence was offered to show that the figures for the two months reflected the previous years as to the material proportions, so far as was possible to judge from the returns previously required by the state.

In establishing local rates a state must be assumed to intend to confine its action within the limits set by the Constitution, and not to seek an unjust advantage from the difficulties of dividing income and expense to which we have referred, but in this case the appellants have contented themselves with a purely negative attitude. There is made even a preliminary objection that the evidence is hearsay. We have not observed that the objection was taken when the evidence was introduced, and if not, it would be too late. Diaz v. United States, 223 U. S. 442, 450, 56 L. ed. 500, 503, 32 Sup. Ct. Rep. 250, Ann. Cas. 1913C, 1138. But it is enough to say that the railroad adopted the only practicable mode of presenting its results, that it exhibited its work sheets and data to the appellants, that the returns were made by the employees in the course of their business, and that if the appellants had desired to question any of the data they could have called for further verification. It seems to us that technical rules are satisfied, and that justice plainly requires this objection to be set aside.

We hardly can avoid approaching the discussion of the merits in the light of a few facts indicating that the probabilities are on the railroad's side. Weight naturally attaches to the opinion of the judge who heard the case. Apart from that, it is not to be forgotten that this same Commission, with others, recognizing the incongruity between the local passenger rates and those in force between different states, applied to the Interstate Commerce Commission to have the latter changed; that the Commission found that the 3-cent rate was not shown to be unreasonable, and that it dismissed their petition, reminding them that the adjustment properly should come not from the United States, but from themselves. Corporation Commission v. Atchison, T. & S. F. R. Co. 31 Inters. Com. Rep. 532. The average haul in Arkansas is shorter than the average of the road, the density of traffic is less, and the maintenance of the road is more expensive. We are aware that there is some contradiction upon this last point, but we have no doubt of the fact that the cost is greater in Arkansas than the average cost of the line.

We do not propose to follow the arguments that have been addressed to us into the elaborate tables of figures. We are satisfied in the main with the discussion the they received below, and shall refer only to one or two details that seem to need mention, without discussing the merits or demerits of the formulas. We are of opinion that the railroad has shown successfully the state rates to be confiscatory, and that even if some errors are detected, they are not enough to change the result. We agree with the district judge that the two months of investigation afforded a basis for argument as to constant conditions. We agree that it is proved that the local expenses are proportionally very much greater than the interstate. In fixing the exact rates it may be that mistakes were made. Perhaps the most important doubt is raised by the fact that the railroad apportioned the cost of maintaining tracks and track structures, so far as not definitely assignable, between freight and passenger service, on the basis of engine ton miles (the weight of the engine in working order, multiplied by the distance it moves in the one service or the other). This criterion, although upheld by the court below, is not regarded as certainly the best by the Interstate Commerce Commission. Western Passenger Fares, 37 Inters. Com. Rep. 1, 13. It gave for the test period 51.19 per cent to freight and 49.31 to passenger, whereas the Commission's figures gave a larger percentage to freight. The result of a difference of eleven per cent would be to convert the deficit alleged by the railroad and found by the court below in intrastate returns into a profit of less than 1 per cent upon the agreed valuation. But the extent of the error, if any, is doubtful, and neither that nor any other possible errors would turn the scale.

The railroad, after getting the actual returns at the 3-cent and 2 1/2-cent passenger rate and the freight rates allowed by the court, deducted the sums necessary to bring the revenue down to what it would have been had the state rates been followed. It is objected that this does not allow for the increase of travel that would follow the deduction. The railroad replies and the court below found that the increase in mainly at the expense of interstate revenue when the combined local rates are less than the interstate one. Whether this exhausts the matter or not, we are of opinion that upon this record the supposed increase is too conjectural properly to affect our conclusion. The direct effect of the reduction is plain,—the remote one is at best a guess.

Light is thrown upon the position of the state by the decision of the Interstate Commerce Commission in Memphis v. Chicago, R. I. & P. R. Co. 39 Inters. Com. Rep. 256, 265: 'The present unduly low rates within Arkansas are due at least in part to the attempt by the Railroad Commission of Arkansas to protect Arkansas shippers and build up Arkansas jobbing centers.' In that case it was intimated that the carriers would be required to remove discriminations resulting from the unduly low rates, as was done in the Shreveport Case. Houston E. & W. T. R. Co. v. United States, 234 U. S. 342, 58 L. ed. 1341, 34 Sup. Ct. Rep. 833. Upon the whole matter we are of opinion that the decree below was right and it is affirmed.

Decree affirmed.
