delivered the opinion of the court.
A bill was filed in the United States District Court for the Western District of North Carolina by a father in his own behalf and as next friend of his two minor sons, one under the age of fourteen years and the other between the ages of fourteen and sixteen, years, employees in a cotton mill at Charlotte, North Carolina, to enjoin the enforcement of the act of Congress intended to prevent interstate commerce in the products of child labor. Act of Sept. 1, 1916, c. 432, 39 Stat. 675.
The District Court held the act unconstitutional and entered a decree enjoining its enforcement. This appeal brings the case here. The first section of the act is in the margin. 1
*269 Other sections of the act contain provisions for its enforcement and prescribe penalties for its violation.
The attack upon the act rests upon- three propositions: First: It is not a regulation of interstate and foreign commerce; Second: It contravenes the Tenth Amendment to the Constitution; Third; It conflicts with the Fifth Amendment to the Constitution.
The controlling question for decision is: Is it within the authority of Congress in regulating commerce among the States to prohibit the transportation in interstate commerce of manufactured goods, the product of a factory in which, within thirty days prior to their removal therefrom, children under the age of fourteen have been employed or permitted to work, or children between the ages of fourteen and sixteen years have been employed, or permitted to work more than eight hours in any day, or more than six days in any week, or after the hour of seven o’clock P. M. or before the hour of 6 o’clock A. M.?
' The power essential to the passage of this act, the Government contends, is found in the commerce clause of the Constitution which authorizes Congress to regulate commerce with foreign nations and among the States.

Champion
v.
Ames,
“If the facility of interstate transportation can be taken away from the demoralization of lotteries, the debasement of obscene literature, the contagion of diseased cattle or persons, the impurity of food and drugs, the like .facility can be taken ■ away from the systematic enticement to and the enslavement in prostitution and debauchery of women, and, more insistently, of girls.”
*271
In
Caminetti
v.
United States,
“The power conferred is to regulate, and the very terms of the grant would seem to repel the contention that only prohibition of movement in interstate commerce was embraced. And the cogency of this is manifest since if the doctrine were applied to those manifold and important subjects of interstate commerce as to which Congress from the beginning has ^regulated, not prohibited, the existence of government under the Constitution would be no longer possible.”
And, concluding the discussion which sustained the authority of the Government to prohibit the transportation of liquor in interstate commerce, the court said:
“. . . the exceptional nature of the subject here regulated is the basis upon which the exceptional power exerted must rest and affords no ground for any fear that such power may be constitutionally extended to things which it may not, consistently with the guarantees of the Constitution, embrace.”
In each of these instances the use of interstate transr portation was necessary to the accomplishment of harmful results. In other words, although the power over interstate transportation was to regulate, that could only be accomplished by prohibiting the use of the facilities of interstate commerce to effect the evil intended.
This element is wanting in the present case. The thing intended to be accomplished by this statute is the denial of the facilities of interstate commerce to those manufacturers in the .States who employ children within the prohibited ages. The act in its effect does not regulate *272 transportation among the States, but aims to standardize ■ the ages at which children may be employed in mining and manufacturing within the States. The goods shipped are of themselves harmless. The act permits them to be freely shipped after thirty days from the time of their removal from the factory. When offered for shipment, and before transportation begins, the labor of their, production is over, and the mere fact that they were intended for interstate commerce transportation does not make , their production subject to federal control under the commerce power.
Commerce "consists of intercourse and traffic . . and includes the transportation of persons and property, as well as the purchase, sale and exchange of commodities.” The making of goods and the mining of coal are not commerce, nor does the fact that these things are to be after-wards shipped or used in interstate commerce, make their production a part thereof. Delaware, Lackawanna & Western R. R. Co. v. Yurkonis, 238. U. S. 439.
Over interstate transportation, or its incidents, the regulatory power of Congress is ample, but the production of articles, intended for interstate commerce, is a matter of local regulation.
When the commerce begins is determined, not by the character of the commodity, nor by the intention of the owner to transfer it to another state for sale, nor by his preparation of it for transportation, but by its actual delivery to a common carrier for transportation, or the actual commencement of its transfer to another state.' (Mr. Justice Jackson in
In re Green,
52 Fed. Rep. 113 This principíelas been recognized often in this court.
Coe
v.
Errol,
It is further contended that the authority of Congress may be exerted to control interstate commerce in the shipment of child-made goods because of the effect of the circulation of such goods in other States where the evil of this class of labor has been recognized by local legislation, and the right to thus employ child labor has been more rigorously restrained than in the State of production. In other words, that the unfair competition, thus engendered, may be controlled by closing the channels of interstate commerce to manufacturers in those States where the local laws do not meet what Congress deems to be the more just standard of other States.
There is no power vested in Congress to require the States to exercise their police power so as to prevent possible unfair competition. Many causes may cooperate to give one State, by reason of local laws or conditions, an economic advantage over others. The Commerce Clause was not intended to give to Congress a general authority to equalize such conditions. In some of the States laws have been passed fixing minimum wages for women, in others the local law regulates the hours of . labor of women in various employments. Business done in such States may be at an economic disadvantage when compared with States which have no such regulations; surely, this fact does not give Congress the power to deny transportation in interstate commerce to those who carry on business where the hours of labor and the rate of compensation for women have not been fixed by a standard in use in other States and approved by Congress.
The grant of power to Congress over the subject of interstate commerce was to enable it to regulate such commerce, and not to give it authority to control the *274 States in their exercise of the police power over local trade and manufacture. '■
- The grant of authority over a purely federal matter was not intended to destroy the local power always existing and carefully reserved to the States in the Tenth .Amendment to the Constitution. .
Police regulations relating to.the internal trade and affairs of the States have been uniformly recognized as within such control. “This,” said this court in

Dewitt,
In the judgment which established the broad power of Congress over interstate commerce, Chief Justice Marshall said (
And in
Dartmouth College
v.
Woodward,
“That the framers of the constitution did not intend to restrain the states in the regulation of their civil institutions, adopted for internal government, and that *275 the instrument they have given us is not to be so construed may be admitted.”
That there should be limitations upon the right to employ children in mines and factories in the interest of their own and the public welfare, all will admit. That such employment is generally deemed to require regulation is shown by the fact that the brief of counsel states that every State in the Union has a law upon the subject, limiting the right to thus employ children. In North Carolina, the State wherein is located the factory in which the employment was had in the present case, no child under twelve years of age is permitted to work..
It may be desirable that such laws be uniform, but our Federal Government is one of enumerated powers; “this principle,” declared Chief Justice Marshall in

v.
New Hampshire,
In interpreting the Constitution it must never be forgotten that the Nation is made up of States to which are entrusted the powers of local government. And to them and to the people the powers not expressly delegated to the National Government are reserved.
Lane County
v.
Oregon,
We have neither authority nor disposition to question the motives of Congress in enacting this legislation. The purposes intended must be attained consistently with constitutional limitations and not by an invasion of the powers of the States. This court has no more important function than that which devolves upon it the obligation to preserve inviolate the constitutional limitations upon the exercise of authority, federal and state, to the end that each may continue to discharge, harmoniously with the other, the duties entrusted to it by the Constitution.
In our view the necessary effect of this act is, by means of a prohibition against the movement in interstate commerce of ordinary commercial commodities, to regulate the hours of labor of children in factories and. mines within the States, a purely state authority. Thus the act in a twofold sense is repugnant to the Constitution. It not only transcends the authority delegated to Congress over commerce but also exerts a power as to a purely local matter to which the -federal authority does, not extend. "_i The far reaching result of upholding the act cannot be more plainly indicated than by pointing out that if Congress can thus regulate matters entrusted to local authority by prohibition of the movement of commodities in interstate commerce, all freedom of commerce will be at an end, and the power of the States over local matters may be eliminated, and thus our system of government be practically destroyed.
*277 For these reasons we hold that this law exceeds the constitutional authority of Congress. It follows that the decree of the District Court must be
Affirmed.
The single question in this case is whether Congress has power to prohibit the shipment in interstate or foreign commerce of any product of a cotton mill situated in the United States, in which within thirty days before the removal of the product children under fourteen have been employed, or children between fourteen and sixteen have been employed more than eight hours in a day, or more than six days in any week, or between seven in the evening and six in the morning. The objection urged against the power is that the States have exclusive control over their methods of production and that Congress cannot meddle with them, and taking the proposition in the sense of direct intermeddling I agree to it and suppose that no one denies it. But if an act is within the powers specifically conferred upon Congress, it seems to me that it is not made any less constitutional because of the indirect effects that it may have, however obvious it may be that it will have those effects, and that we are not at liberty upon such grounds to hold it void.
The first step in my argument is to make plain what no one is likely to dispute — that the statute in question is within the power expressly given to Congress if considered only as to its immediate effects and that if invalid it is so only upon some collateral ground. The statute confines itself to prohibiting the carriage of certain goods in interstate or foreign commerce. Congress is given power to regulate such commerce in unqualified terms. It would not be argued today that the power to regulate does not include the power to prohibit. Regulation means the prohibition of something, and when interstate
*278
commerce is the matter to be regulated I cannot doubt that the regulation may prohibit any part of such commerce that Congress sees fit to forbid. At all events it is established by the
Lottery Case
and others that have followed it that a law is not beyond the regulative power of Congress merely because it prohibits certain transportation out and out.
Champion
v. Ames,
The question then is narrowed to whether the exercise of its otherwise constitutional power by Congress can be pronounced unconstitutional because of its possible reaction upon the conduct of the States in a matter upon which I have admitted that they are free from direct control. I should have thought that that matter had been disposed of so fully as to leave no room.for doubt. I should have thought that the most conspicuous decisions of this Court had made it clear that the power to regulate commerce and other constitutional powers could not be cut down or qualified by the fact that it might interfere with the carrying out of the domestic policy of any State.
' The manufacture of oleomargaiuie is as much a matter of state regulation as the manufacture of cotton cloth. Congress levied a'tax upon the compound when colored so as to resemble butter that was so great as obviously to prohibit the manufacture and sale. In a very elaborate discussion the present Chief Justice excluded any inquiry into the puipose of an act which apart from that purpose. was within the power of Congress.
McCray
v.
United States,
The notion that prohibition is any less prohibition when applied to things now thought evil I do not understand. But if there is any matter upon which civilized countries have agreed — far more unanimously than they have with regard to intoxicants and some other matters over which this country is now emotionally aroused — it is the evil of premature and excessive child labor. I. should havé thought that if we were to introduce our own moral conceptions where in my opinion they do not belong, this was preeminently a case for upholding the exercise of all its powers by the United States.
But I had thought that the propriety of the exercise of a power admitted to exist in some cases was for the consideration of Congress alone and that this Court always had disavowed the right to intrude its judgment upon questions of policy or morals, ^t is not for this Court to pronounce when prohibition is necessary to regulation if it ever may be necessary — to say that it is permissible as against strong drink but not as against the product of ruined lives.
*281 The act does not meddle with anything belonging to the States. They may regulate their internal affairs and their domestic commerce as they like. But when they seek to send their products across the state line they are no longer within their rights, if there were no Constitution and no Congress their power to cross the line would depend upon then.’ neighbors. Under the Constitution such commerce belongs not to the States but to Congress to regulate. It may carry out its views of public policy whatever indirect effect they may have upon the activities of the States. Instead of being encountered by a prohibitive, tariff at her boundaries the State encounters the public policy of the United States which it is for Congress to express. The public policy of the United States is shaped with a view to the benefit of the nation as a whole. If, as has been the case within the memory of men still living, a State should take a different view of the propriety of sustaining a lottery from that which generally prevails, I cannot believe that the fact would require a different decision from that reached in Champion v. Ames. Yet in that case it would be said with quite as much force as in this that Congress was attempting to inter-meddle with the State’s domestic affairs. The national welfare as understood by Congress may require a different attitude within its sphere from that of some self-seeking State. It seems to me entirely constitutional for Congress to enforce its understanding by all the means at its command.
