APPEALS FROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF ILLINOIS.

*528 MR. JUSTICE DAY delivered the opinion of the court.
These cases are appeals from the Circuit Court of the United States for the Northern District of Illinois and were submitted upon oral argument and printed record and briefs in No. 405. They involve the same question and hence will be disposed of together. The petition was filed in the Circuit Court under the third section of the Elkins act, February 19, 1903, c. 708, 32 Stat. 847, providing for the institution of such suit whenever the Interstate Commerce Commission shall have reasonable grounds for believing that any common carrier is engaged in the carriage of passengers or freight traffic between given points at less than the published rates on file, or is granting any discrimination forbidden by law.
An injunction was issued restraining the express companies from "issuing any frank or other document for the free transportation of property to the following persons, to wit: the officers, agents, attorneys, and employes of said defendant and their respective families; the officers and employes of other express companies and their respective families; the officers and employes of any railroad or any other common carrier subject to the act to regulate commerce and its amendments, and their respective families; or to any of said persons; and from transporting *529 and forwarding for said persons above named or any of them, without demanding and receiving the lawful rate of payment therefor, any shipments of property subject to the provisions of said interstate commerce act and its amendments."
The facts are not seriously in dispute and were stipulated at the trial and show that it has been the custom of express companies for many years to issue franks such as are embraced in the injunction. These franks were not issued except to officers and employes of the companies and their families, and to the officers and employes of other express companies and transportation companies and members of their families, in exchange for passes issued by the latter companies to the officers and employes of the express companies. The franks provided that they should not be used for business packages or for transportation of extra heavy weight, money, bonds, jewelry, live stock, or business consignments, and only for the personal packages of the holder of such frank, he being required to assume all risk of loss or damage from whatever cause to property carried under the frank.
The question is, Does the Interstate Commerce law prohibit express companies from giving free transportation of personal packages to their officers and employes and members of their families, and to the officers of other transportation companies and members of their families in exchange for passes issued by the latter to the officers of the express companies? The Circuit Court held the affirmative of this proposition.
It is the contention of the Government that such transportation is forbidden by § 2 of the act of February 4, 1889, c. 104, 24 Stat. 379, forbidding the transportation of property or passengers subject to the provisions of the act for any person for a greater or less compensation for any service rendered or to be rendered, in the transportation of passengers or property, than it charges, demands, collects, or receives from any other person for doing for him the like service, and by § 3 of the same act (24 Stat. 379, 380) which makes it unlawful to give any undue preference or advantage to any particular persons or *530 locality, and by the provisions of the Elkins act hereafter quoted.
Without considering whether the case at bar is covered by the sections of the Interstate Commerce act referred to, an injunction is authorized under § 3 of the Elkins act, where a common carrier is engaged in the carriage of passengers or freight at less than the published rate on file, and we shall limit our attention to certain provisions of the Elkins law in this connection. Section 1 of the Elkins act provides (as amended by the Hepburn act, June 29, 1906, c. 3591, 34 Stat. 584, 587):
"The wilful failure upon the part of any carrier subject to said acts to file and publish the tariffs or rates and charges as required by said acts, or strictly to observe such tariffs until changed according to law, shall be a misdemeanor, and upon conviction thereof the corporation offending shall be subject to a fine of not less than one thousand dollars nor more than twenty thousand dollars for each offense.

* * * * * * * *
"It shall be unlawful for any person, persons, or corporation to offer, grant, or give, or to solicit, accept, or receive any rebate, concession, or discrimination in respect of the transmission of any property in interstate or foreign commerce by any common carrier subject to said act to regulate commerce and the acts amendatory thereof, whereby any such property shall by any device whatever be transported at a less rate than that named in the tariffs published and filed by such carrier, as is required by said act to regulate commerce and the acts amendatory thereof, or whereby any other advantage is given or discrimination is practiced.
"Whenever any carrier files with the Interstate Commerce Commission or publishes a particular rate under the provisions of the act to regulate commerce or acts amendatory thereof, or participates in any rates so filed or published, that rate as against such carrier, its officers, or agents, in any prosecution begun under this act, shall be conclusively deemed to be the legal rate, and any departure from such rate, or any offer to *531 depart therefrom, shall be deemed to be an offense under this section of this act."
Section six of the Interstate Commerce act, as amended by the same law, provides:
"Nor shall any carrier charge or demand, or collect or receive a greater or less or different compensation for such transportation of passengers or property, or for any service in connection therewith, between the point named in such tariffs than the rates, fares and charges which are specified in the tariff filed and in effect at the time; nor shall any carrier refund or remit in any manner or by any device any portion of the rates, fares, and charges so specified, nor extend to any shipper or person any privileges or facilities in the transportation of passengers or property except such as are specified in such tariffs: Provided, That whenever the word `carrier' occurs in this act it shall be held to mean `common carrier.'"
The amendment to the Interstate Commerce act by the act of June 29, 1906, c. 3591, 34 Stat. 584, brought express companies within the terms of the act. The express companies were therefore obliged to file and publish their rates for the transportation of property under § 6 of the Interstate Commerce act as amended, and it is admitted in the record that they have done so.
The provisions of the Elkins act to which we have referred have been the subject of consideration in recent cases before this court. New York, New Haven & Hartford R.R. Co. v. Interstate Commerce Commission, 200 U.S. 361; Armour Packing Co. v. United States, 209 U.S. 56, 71. It is unnecessary to repeat the discussion had in those cases as to the prior legislation and the reasons of public policy which led up to the enactment of the sections of the Elkins act above quoted. It is enough to say that it was the purpose of this law to require the publication and posting of tariff rates, open to public inspection, and at the service of all shippers alike; to prohibit and punish secret departures from the published rates, and to prevent and punish rebating, preferences and all acts of undue discrimination. *532 As was said by Mr. Justice White, speaking for the court in New York, New Haven & Hartford R.R. Co. v. Interstate Commerce Commission, supra:
"The all-embracing prohibition against either directly or indirectly charging less than the published rates shows that the purpose of the statute was to make the prohibition applicable to every method of dealing by a carrier by which the forbidden result could be brought about. If the public purpose which the statute was intended to accomplish be borne in mind, its meaning becomes, if possible, clearer."
In view of the interpretation thus given to the act we think it cannot be doubted that the transportation of property, such as shown in this case, upon franks issued by the express companies, is within the terms of the act. It permits those who hold these franks to obtain the transportation of such property as is covered thereby without compensation, or, if the transportation has been paid, it is refunded to the shipper upon the presentation of the frank. Within the terms used in the Elkins act, such transportation enables one class of persons to obtain transportation at a different and less rate than that named in the published rates.
It is contended that such transportation is not within the terms of the act, as it was not the purpose of Congress to regulate in these provisions gratuitous transportation, but the purpose was to prevent discriminations, rebating and so forth, where property has been carried by a common carrier for hire; that it is a departure from the rates charged for that class of transportation which is the evil to be remedied, and the only one covered by the terms of the act. But the power of Congress over interstate transportation embraces all manner of carriage of that character  whether gratuitous or otherwise  and, in the absence of express exceptions, we think it was the intention of Congress to prevent a departure from the published rates and schedules in any manner whatsoever. If this be not so, a wide door is opened to favoritism in the carriage of property, in the instances mentioned, free of charge.
*533 If it is lawful, in view of the provisions of the Interstate Commerce act, to issue franks of the character under consideration in this case, then this right must be founded upon some exception incorporated in the act, and it is the contention of the learned counsel for the appellant that such exception is found in the proviso in § 1 of the Hepburn act. This section is given in part in the margin.[1]
*534 As originally reported, this act did not apply to express companies. The section was originally framed with the intention of making a provision for railroad carriers. It is contended that the proviso brings common carriers within the exception of the act, and therefore necessarily includes the express companies. There is no doubt that a proviso has not infrequently been the means of introducing into a law independent legislation, notwithstanding it is the true office of a proviso to restrict the sense or make clear that which has gone before and which might be doubtful because of the generality of the language used. United States v. Dickson, 15 Pet. 141, 163. This court has had occasion to hold more than once that language used in provisos shows the legislative intention to bring in new matter rather than to limit or explain that which has gone before. Georgia Banking Co. v. Smith, 128 U.S. 174; Interstate Commerce Commission v. Baird, 194 U.S. 25, 36, 37.
While, therefore, a proviso may sometimes be construed as extending rather than limiting legislation, each statute must depend upon its own terms, and a proviso will be given such construction as is consistent with the legislation under construction.
Turning to § 1 of the Hepburn act, it is apparent that all that immediately precedes the proviso appertains to the carriage of passengers, for common carriers are forbidden to issue or give any free ticket, free pass or free transportation for passengers, except to its employes, etc. Until we come to the proviso, the act is clearly thus limited. It is then enacted that this provision, that is, the previous part of the enactment which refers only to the transportation of passengers, shall not be construed to prohibit the interchange of passes for the officers, agents and employes of common carriers and their families, or to prohibit any common carrier from carrying passengers free in certain cases.
While it is true the language here used has reference to common *535 carriers and by the terms of the Hepburn act express companies are within that description, yet the proviso is as clearly limited to the carriage of passengers and the interchange of passes for officers, agents and employes of common carriers and their families, as is the body of the section itself.
It is contended that this section if limited to the carriage of passengers was unnecessary in view of the concluding part of § 22 of the act of February 4, 1887, c. 104, 24 Stat. 379, 387, as amended by the acts of March 2, 1889, c. 382, 25 Stat. 855, 862, and February 8, 1895, c. 61, 28 Stat. 643, which provides: "Nothing in this act shall be construed to prevent railroads from giving free carriage to their own officers and employes, or to prevent the principal officers of any railroad company or companies from exchanging passes or tickets with other railroad companies for their officers and employes;" etc.
But we are to consider the language which Congress has used in passing a given law, and when the language is plain and explicit our only province is to give effect to the act as plainly expressed in its terms. We are clearly of the opinion that, without doing violence to the language used in § 1  including the proviso  its terms cannot be held to include the transportation of goods.
It is very likely that there is no substantial reason why Congress should not extend to express companies, their officers, agents and employes, corresponding privileges for free carriage of goods with those which are given to the officers, agents and employes of railroad companies in respect to transportation of persons, but  if the law is defective in this respect  the remedy must be applied by Congress and not by the courts.
We find no error in the decrees of the Circuit Court, and the same are
Affirmed.
