after stating the case, delivered the opinion of the court.
There is nothing in the provisions of the act of Louisiana providing for the appointment of two gaugers of coal and coke boáts, which can properly be considered.as regulations of commerce, in conflict with the power vested in Congress over the subject. ’ They only prescribe -the rule by which the capacity of the carrying vessels of coal and coke can be determined, and the weight of the coal or coke carried ascertained, which may be readily done at any time. They were adopted for the convenience of the owners of the boats and loads. They are properly to be regarded as a part of those innumerable police regulations which every State may enact for the convenience and comfort of its inhabitants in the conduct of their business. *598 They do not add to the increase or to the diminution of the productions of the State or to the facility of their transportation or of their loading or landing. They may in some cases' in a slight degree affect commerce, but not to -such an extent or in such a sense as to be properly designated as regulations of commerce.
As this court said in
Smith
v. Alabama,
."We do not think that the statute of Louisiana was in- conflict with the commercial power of Congress prescribed by the Constitution, and the Supreme Court of Louisiana did not err, therefore, in sustaining it. It provided only a regulation for the measurement of the coal and coke boats on the Mississippi, and of the coal and coke carried, which neither increased nor impaired the commerce of the country in the carrying form of the boats or in the coal and coke carried.
*600
.Nor do we perceive that the statute of Louisiana in any respect lays an impost or duty on imports or exports from Pennsylvania and Louisiana. The terms “ imports ” and “ exports ” apply only to articles imported from foreign countries or exported to them. The inhibition imposed is the laying of duties on imports from foreign countries, and not on such as came from one State to another. This was directly held in
Woodruff
v. Parham,
Nor do we perceive that there is any inhibition to the statute of Louisiana in the act approved February 20, 1811, c. 21, 2 Stat. 641, enabling the people of the Territory of Orleans to forma constitution and'state government and for the admission of the State of Louisiana into the Union on an equal footing with the original States, or in the act of Congress which provides, as the unalterable condition on which the State of Louisiana was admitted into the Union, that the river Mississippi and the navigable rivers and waters leading into the same or into the Gulf of Mexico shall be common highways find forever free, as well to the inhabitants of said State as to other citizens of the United States, without any tax, duty, impost, or toll therefor imposed by the said State. The tax, duty, impost, or toll thus referred to and thus prohibited are such as are directed against the commerce of the rivers, and not such as are imposed by any regulation for convenience in the measurement or storage of coal, or coke carried. The freedom contemplated is that which would be destroyed by denying equality of right to any particular class of vessels or mode of navigating the Mississippi and other rivers leading into the Gulf of Mexico. All such rivers are to be deemed highways and equally open to all persons who choose to pursue commerce upon them.
Nor is there any discrimination in the transportation of the coal and coke from Alabama and that from Pennsylvania, as in any respect impairs the efficiency of the laws of Louisiana. The difference between the transportation of the coal and coke from Pennsylvania and from Alabama is only the difference *601 arising from one being transported by water and the other by land. There is a difference arising between water and .land carriage, arising from the nature of the two modes, but not one created by legislation, direct or indirect, or by any efforts of the state legislature to give or recognize a discrimination in the case of either.
Judgment affirmed.
