delivered the opinion of the court.
A statute of the State of Kansas makes it a misdemeanor, punishable by fine or imprisonment, or both, for any person to transport into the State cattle from any point south of the south line of the State, except for immediate slaughter, without hav
The obvious purpose of the law was to guard against the introduction into the State of cattle infected with a communicable disease. It undoubtedly restricts the absolute freedom of interstate commerce in cattle, but only to the extent that all cattle coming to cross the guarded boundary are subjected to inspection to ascertain whether or not they are diseased. If healthy they are admitted, if diseased they are excluded. The validity of such a restriction for such purposes has been frequently considered by this court, and the principles applicable to the settlement of the question have been clearly defined. The governmental power over the commerce which is interstate is vested exclusively in the Congress by the commerce clause of the Constitution, and therefore is withdrawn from the States. It is not now necessary to cite the many cases supporting this proposition, or to consider some expressions in the books somewhat qualifying its generality, because in carefully chosen .words it has recently been affirmed by us. At this term, Mr. Justice Peckham, speaking for the court, said: “That any exercise of state authority, in whatever form manifested, which directly regulates interstate commerce, is repugnant to the commerce clause of the Constitution is obvious.”

But though it may not legislate for the direct control of interstate commerce, the State may exercise any part of the legis
“So, if a State, in passing laws on subjects acknowledged to be within its control, and with a view to those subjects shall adopt a measure of the same character with one which Congress may adopt, it does not derive its authority from the particular power which has been granted, but from some other, which remains with the State, and may be executed by the same me<\ns. All experience shows, that the same measures, or measures scarcely distinguishable from each other, may flow from distinct powers; but this does not prove that the powers themselves are identicaL Although the means used in their execution may sometimes approach each other so nearly as to be confounded, there are other situations in which they are sufficiently distinct to establish their individuality.
“In our complex system, presenting the rare and difficult scheme of one general government, whose action extends over the whole, but which possesses only certain enumerated powers; and of numerous state governments, which retain and exercise all powers not delegated to the Union, contests respecting power must arise. Were it even otherwise, the measures taken by the respective governments to execute their acknowledged powers, would often be of the same description, and might, sometimes, interfere. This, however, does not prove that the one is exercising, or has a right to exercise, the powers of the other.”
The State may not, however, for this purpose exclude all animals, whether diseased or not, coming from other States,
