delivered the opinion of the court.

In Woodruff v. Parham (8 Wall. 123), we had occasion to consider the constitutional validity of an ordinance of the city of Mobile under the provisions of which had been assessed, for municipal purposes, a tax upon sales in that city of certain goods and merchandise, the product of States other than Alabama.. The ordinance, in its application to articles carried into Alabama from other States, was assailed as being inconsistent with the constitutional inhibition upon the States levying imposts or duties on imports or exports — with the power of Congress to regulate commerce with foreign nations and among the several States — and with that clause which declares that the citizens of each State shall be entitled to all the immunities and privileges of citizens of the several States.

Touching the first of these propositions it was ruled that the[*438] term import, as used in. sect. 10, art. 1, of tbe Constitution, had reference to articles imported from foreign countries, and not to such as were brought from one of the States of the Union into another. In the argument, Brown v. Maryland (12 Wheat. 419) was cited in support of the proposition that the whole ordinance, in its application to articles brought from other States to Mobile for sale, was an unauthorized regulation of inter-state commerce. Upon that branch of the case, we said: “If the court there [in Brown v. Maryland] meant to say that a tax levied on goods from a sister State, which wak not levied on goods of a similar character produced within the State, would be in conflict with the clause of the Constitution giving Congress the right to regulate commerce; among the States, as much as the tax on foreign goods, then under consideration, was in conflict with the authority to regulate commerce with foreign nations, we agree to the proposition.”

In a subsequent portion of our opinion in Woodruff v. Parham, it was said: “ But we may be asked, is there no limit to the power of the States to tax the produce of other States brought within their borders ? And can they so tax them as to drive them out or altogether prevent their introduction or their transit over their territory ? ,The case before us is a simple tax on sales of merchandise imposed alike upon all sales made in Mobile, whether the sales be made by a citizen of Alabama, or of another State, and whether the goods sold are the products of that State or of some other. There is. no attempt to discriminate injuriously against the products of other States, or the rights of their citizens, and the casé is not, therefore, an attempt to fetter commerce among the States, or' to deprive the citizens of other States of any privilege or immunity possessed by citizens of Alabama. But a law having such operation'would, in our opinion, be an infringement of the provisions of the Constitution which relate to those subjects, and, therefore, void.”

In Hinson v. Lott (8 Wall. 148), we upheld a. statute of Alabama, imposing taxes upon the sale of spirituous liquors within its limits, upon the ground that it did not discriminate against the products of other States, and only subjected them to the same taxation imposed upon similar articles manufactured[*439] in that State. Had the statute been susceptible of a different construction, it would have been held to be repugnant to the Constitution.

In Ward v. Maryland (12 id. 418), we examined the pro visions of a statute of Maryland which, among other things, required of persons, not permanent residents of that State, before selling or offering for sale within the limits of the city of Baltimore, any goods, wares, or merchandise whatever, other than agricultural products and articles manufactured in that State, to obtain a license therefor. The amount exacted for such license was larger than the statute required of resident traders engaged in like business. In declaring the statute to be repugnant to the Federal Constitution, we said that, “inasmuch as the Constitution provides that the citizens of each State shall be entitled to all privileges and immunities of citizens in the several States, it follows that the defendant might lawfully sell or offer or expose to sale, within the district described in the indictment, any goods which the permanent residents of the State might sell or offer or expose for sale in that district, without being subjected to any higher tax or excise than that exacted by law of such permanent residents.”

Upon the same ground, in the more recent case of Welton v. State of Missouri (91 U. S. 275), we held void a statute of Missouri imposing a peddler’s license-tax upon persons going from place to place to sell patent and other medicines, goods, wares, or merchandise, except 'books, charts, maps, and stationery, not the growth, product, or manufacture of that State, and which did not impose a like tax upon the sale of similar articles, the growth, product, or manufacture of Missouri.

In view of these and other decisions of this court, it must be regarded as settled tbat no State can, consistently with the Federal Constitution, impose upon the products of other States, brought therein for sale or use, or upon citizens because engaged in the sale therein, or the transportation thereto, of the products of other States, more onerous public burdens or taxes than it imposes upon the like products of its own territory.

If this were not so, it is easy to perceive how the power of Congress to regulate commerce with foreign nations and among the several States could be practically annulled, and the equality[*440] of commercial' privileges secured by the Federal Constitution to citizens of the several States be materially abridged and impaired. “ Over whatever other interests of the country,” said Mr. Webster, “this government may diffuse its benefits and blessings, it will always be true, as matter of historical fact, that it had its immediate origin in the necessities of commerce;' and for its immediate object, the relief of those necessities, by removing their causes, and by establishing a uniform and steady system.” But State legislation such as that indicated in the cases which have been cited, if maintained by this court, would ultimately bring our commerce to that “ oppressed and degraded state,” existing at the adoption of the present Constitution, when the helpless, inadequate Confederation was abandoned • and a national government instituted,. with full power over the entire subject of commerce, except that wholly internal to the States composing the Union.

How far the principles enunciated in the foregoing cases control- the determination of the one before us, we now proceed to inquire.

By an act of the General Assembly of Maryland, passed in 1827, authority was given to the mayor and city council of Baltimore to regulate, ¡establish, charge, and collect to their use such rate of wharfage as they might think reasonable, of and from all vessels resorting to or lying at, landing, depositing, or transporting goods or articles, other than the products of that State, on any wharf or wharves belonging to that municipal corporation, or any public wharf in the city other than the wharves belonging to or rented by the State, and that part of Pratt Street wharf, theretofore reserved for the use of the citizens of that State. Maryland Code of Public Local Laws, art. 4, sect. 945. .

In pursuance of that act the city, by its constituted authorities, in the year 1858, passed an act regulating the public w.iarves. By its thirty-third section it is declared that all goods, wares, or merchandise landed on the public wharves from on board any vessels lying at said whaiwes, or placed thereon for the purpose of shipment or exposure for sale, other than the product of the State of Maryland, shall pay wharfage according to.certain rates therein prescribed.- The thirty-fifth[*441] section declares that “all-vessels belonging to or-lying at, land ing, depositing, or transporting goods or articles other than the production of this State, on or from any wharf or wharves belonging to the mayor and city council, or any public wharf in the said city, other than the wharves belonging to or rented by the State, shall be chargeable with the wharfage as fixed by this ordinance, upon all goods or articles landed or deposited on any wharf or wharves belonging to the said mayor and city council; and the master or owner of the vessel so depositing, landing, or transporting said goods or articles, shall be responsible for the same.” The- ordinance contained other sections providing for its enforcement.

The appellant Guy, a resident citizen of Accomac County, Virginia, was engaged in the year 1876 in sailing a schooner, of which he was master and part-owner, from that county to Baltimore, laden with potatoes raised in Virginia. In June of that year, he landed his vessel at one of the public wharves belonging to the city (not that part of the Pratt Street wharf reserved), and discharged therefrom two hundred and twenty barrels of potatoes. Under the authority of the foregoing statute and ordinance, the city harbor-master demanded of him the payment of |4.40 as wharfage. . He refused to comply with that demand, and, being sued by the city, judgment was rendered against him in the court of a justice of the peace, which was affirmed by the City Court of Baltimore, the highest court of Maryland in which a decision of the case could have been had.

It is admitted that such wharfage dues are not and never have been assessed against parties or vessels bringing to that port potatoes or other articles grown in the State of Maryland.

The argument in support of the statute and ordinance upon which the judgment below rests is that the city, by virtue of its ownership of the wharves in question, has the right, in its discretion, to permit their use to all vessels landing thereat with the products of Maryland; and that those operating vessels, laden with the products of other States, cannot justly complain, so long as they are not required to pay wharfage fees in excess of reasonable compensation for the use of the city’s property.

[*442] This proposition, however ingenious or plausible, is unsound both upon principle and authority. The municipal corporation of Baltimore was created by the State of Maryland to promote the public interests and the public convenience. The wharf at which appellant landed his vessel was long ago dedicated to public use. The public for whose benefit it was acquired, or who are entitled to participate in its use, are not ^ alone those who may engage in the transportation to the port of Baltimore of the products of Maryland. It embraces, necessarily, all engaged in trade and commerce upon the public navigable waters of the United States. Every vessel employed in such trade and commerce may traverse those waters without let or hinderance from local or State authority; and the national Constitution secures to all, so employed, without reference to the residence or citizenship * of the owners, the privilege of landing at the port of Baltimore with any cargo whatever, not excluded therefrom by, or under the authority of, some statute in Maryland enacted in the exertion of its police powers. The State, it will be admitted, could not lawfully impose upon such cargo any direct public burden or tax because it may consist, in whole or in part, of the products of other States. The concession of such a power to the States would render wholly nugatory all national control of commerce among the States, and place the trade and business of the country at the mercy of local regulations, having for their object to secure exclusive benefits to the citizens and products of particular States. But it is claimed that a State may empower one of its political agencies, a mere municipal corporation representing a portion of its civil power, to burden inter-state commerce by exacting from those transporting to its wharves the products of other States wharfage fees, which it does not exact from those bringing to the same wharves the products of Maryland. The city can no more do this than it or the State could discriminate against the citizens and products of other States in the use of the public streets or other public highways. ' The city of Baltimore, if it chooses, can permit the public wharves; which- it owns, to be used without charge. Under the authority of the State, if may also exact wharfage fees, equally, from all who use its improved wharves, provided such charges do not exceed[*443] what is fair remuneration for the use of its property. Packet Company v. St. Louis, supra, p. 423; Vicksburg v. Tobin, supra, p. 430; Packet Company v. Keokuk, 95 U. S. 80. But it cannot employ the property it thus holds for public use so as to hinder, obstruct, or burden inter-state commerce in the interest of commerce wholly internal to that State. The fees which it exacts to that end, although denominated wharfage dues, cannot be regarded, in the sense of our former decisions, as compensation merely for the use' of the city’s property, but as a. mere expedient or device to accomplish, by indirection, what the State could not accomplish by a direct tax, viz., build up its domestic commerce by means of unequal and oppressive burdens upon the industry and business of other States.

Such exactions, in the name of wharfage, must be regarded as taxation upon inter-state commerce. Municipal corporations, owning wharves upon the public navigable waters of the United States, and quasi public corporations transporting the products of- the country, cannot be permitted by discriminations of that character to impede commercial intercourse and traffic among the several States and with foreign nations.

In the exercise of its police powers, a State may exclude from its territory, or prohibit the. sale therein of any articles which, in its judgment, fairly exercised, are prejudicial to the health or which would endanger the lives or property of its people. But if the State, under the guise of exerting its police powers, should make such exclusion or prohibition applicable solely to articles, of that kind, that may be produced or manufactured in other States, the courts would find no difficulty in holding such legislation to be in conflict with the Constitution of the United States.

The power of the national government over commerce with foreign nations and among the several States is broad and comprehensive. It reaches the interior of every State of the Union, so far as it may be necessary to protect the products of other States and countries from discrimination by. reason of their foreign origin. Brown v. Maryland, 12 Wheat. 419.

Nothing can be clearer than that the statute of Maryland and the. ordinance of the city of Baltimore, in the respects[*444] adverted to, are in conflict with the power of Congress over the subject of commerce.

The judgment is reversed, with directions to dismiss the action against the appellant, with his costs against the city.

So ordered.
