right. See, also, Burlington, Cedar Rapida &c. Railway v. Dey, 82 Iowa, 312, 338. All that we are required to hold in this ease is that, where a joint tariff between two or more roads has been agreed upon, such tariff is as’much within the control of the legislature as if it related only to transportation over a single line.
2. The more difficult question is that connected with the reasonableness of the rates. The presumption is that the rates ffxed by the Commission are reasonable, and the burden of proof is upon the railroad companies to show the contrary. Dow v. Beidelman, 125 U. S. 680; Chicago &c. Ry. Co. v. Tompkins, 176 U. S. 167, 173. Indeed, the act itself provides, section three, subdivision C, “the rates established by said Commission shall go into effect within ten days, . . . and from and after that time the schedule of rates so established shall be prima facie evidence in all the courts of this State that such through rates are reasonable for transportation of freight and cars upon the railroads over which such schedule shall have been fixed.”
■ In fixing the through rates for hard coal in carload Jots from Duluth to interior points in Minnesota, the Commission set apart to the St. Paul and Duluth Company $1 per ton of the joint tariff, and as this was the same amount which that road had réceived under the prior arrangement, no question is made as to its reasonableness, and no appeal was taken by that road. The remainder of the joint tariff is paid to the Minneapolis and St. Louis Company, plaintiff in error, which was left to settle with the other roads interested in the tariff.
According to the tariff fixed by agreement between the companies prior to the action of the Commission a charge was made from Duluth to Hopkins, nine miles from Minneapolis, of $1.75, of which $1 was paid to the St. Paul and Duluth road (160 ipiles) and the remainder, 75 cents, to the Minneapolis and St. Louis road for a transportation of nine miles. This rate was gradually increased to stations beyond Hopkins until Norwood,' forty miles from Minneapolis, was reached, where it was fixed at $2.50. The same rate was retained to Boyd, 153 miles from Minneapolis. This rate of $2.50 appears to have been a purely
