delivered the opinion of the Court.
Turner, Dennis & Lowry Lumber Company brought this action against the Chicago, Milwaukee & St. Paul Railway Company in the federal court for western Missоuri to recover $40 alleged to have been illegally exacted in December, 1921. That sum was collected by the cаrrier, in accordance with a demurrage tariff duly filed, as a so-called penalty at the rate of $10 a day for the detention of a car containing lumber shipped interstate over thedefendant’s railroad to the plaintiff at Aberdeеn, South Dakota, and there held at its request for reconsignment. The claim that the charge was illegally exacted rests upon the contentions that imposition of a penalty exceeds the statutory authority conferred upon the Commissiоn; that if the Interstate Commerce Act be construed as conferring such authority, the provision is void, because s Congress is withоut power to authorize the Commission to impose it, since prescribing a penalty is a legislative function which cannot be delegated; and that, even if authority to impose a penalty was validly conferred, this particular provision is vоid, because, by imposing the penalty without notice, there is a denial of due process of law; and that, being imposed only on shippers of lumber, there is a denial of equal protection of the laws.
The tariff in question provides:
“ To prevent undue detention of еquipment under present emergency, the following additional penalties for detention of equipment will apply:
“ On cars loaded with lumber held for reconsignment a storage charge of $10 per car will be assessed for each day ór fractional part of a day that a car is held for reconsignment after 48 hours after the hour at which free time begins to run under the demurrage rules.
*261 “ These charges will be assessed regardless of whether cars .are held on railroad hold tracks or transfer tracks, including consignee’s or other private sidings, and-will be in addition to any existing demurrage and storage charges.”
The gеneral nature of charges under the Uniform Demurrage Code was considered in
Swift & Co.
v.
Hocking Valley Ry. Co.,
By stipulation in writing a jury was.waived; the.case was submitted on agreеd facts; these were adopted by the court as a special finding of facts; and judgment was entered for the defendant on November 8, 1924, 2 Fed. (2d) 291. The District Court had jurisdiction under Paragraph Eight of § 24 of the Judicial Code, despite the small amount, because the suit arises under a law regulating commerce.

Rice, 247
U. S. 201. Preliminary resort to the Interstate Gommerce Commission was unnecеssary, because no administrative question is presented.
Great Northern Ry. Co.
v.
Merchants Elevator Co.,
The efficient use of freight cаrs is . an essential of an adequate transportation system. To secure it, broad powers are conferred upоn the Commission. Compare

v.
New River Co.,
265 U,,S. 533;
Avent
v.
United States,
AH demurrage charges have a double purpose. One is to secure compensation for the usе of the car and of the track which it occupies. The other is to promote car efficiency by providing a dеterrent against undue detention.
Pennsylvania R. R. Co.
v.
Kitanning Iron & Steel Co.,
The further contentions are that thеre was a denial of due process of law because the so-called penalty was imposed without noticе; and that there was a denial of equal protection of the laws, because the charge was applicable only to cars loaded with lumber. The demurrage charge is, however, a tariff provision and not a penal law, and thus thе tariff duly filed charges the shipper with the requisite notice. And neither the Constitution nor the rule of reason requires that either freight or demurrage charges or the reconsignment privilege shall be the same for all commodities. We find no reason to disturb the basis of the Commission’s classification.
Affirmed.
Notes
During the period of federal control this tariff was filed with the Interstate Commerce Commission, as provided by law, to be effective October 20, 1919. After the termination of federal control the defendant and other railroads continued to maintain the provision -in their published tariffs until.March 13, 1922, when it was cancelled in pursuance of the decision and order of the Commission in American Wholesale Lumber Co. v. Director General, 66 I. C. C. 393.
