To the ordinary mind it seems a somewhat startling proposition that a manufacturing corporation, located and doing its main business in a distant city, having no manufactory in North Carolina, no stock in trade, no place for the sale of its goods there, and no agent authorized to sell them, can be compelled to take out a license required of all those 'engaged in the business of selling,' from the mere fact that it had done what hundreds of others were doing daily,—sent a single machine there upon a written order of a customer, and under an ordinary C. O. D. consignment. If this may be done, the revenues of every state may be largely increased by adopting a similar system, since a large part of the business of retail shops in the principal cities is done by orders received, filled, and the goods delivered in the same way. Of course, it is impossible to estimate the number of business houses in other states which are accustomed to collect their accounts in this manner.

If this were the law it would also follow that the consignor of every cargo of wheat sent to New York for export under a bill of lading, accompanied by a draft for the payment of the money in the usual method, might be compelled to take out a license in the state of New York as a dealer in produce, notwithstanding that all the real business was done in Chicago or North Dakota.

So, too, what the state may do directly it may authorize its municipalities to do, and if, under legislative sanction, each of the large towns in the state of North Carolina saw fit to adopt a similar license tax, the consequence would be, not a simple interference with interstate commerce, but a practical destruction of one important branch of it.

While it may be entirely true that the property in the thing sold does not pass under a C. O. D. consignment until delivery of the goods and payment to the carrier, and hence it may be said that the sale is not completed until then, yet, as matter of fact, the bargain is made, and the contract of sale completed as such, when the order is received in Chicago, and the machine shipped in pursuance thereof.

A sale really consists of two separate and distinct elements: first, a contract of sale, which is completed when the offer is made and accepted; and, second, a delivery of the property which may precede, be accompanied by, or follow, the payment of the price, as may have been agreed upon between the parties. The substance of the sale is the agreement to sell, and its acceptance. That possession shall be retained until payment of the price may or may not have been a part of the original bargain, but in substance it is a mere method of collection, and we have never understood that a license could be imposed upon this transaction except in connection with the prior agreement to sell, although, in certain cases arising under the police power, it has been held that the sale is not complete until delivery, and sometimes not until payment. Were it not for the opinion of the supreme court of North Carolina, we should have said that the words 'engaged in the business of selling the same within the state' had reference to the word 'selling' in its popular and ordinary sense of selling from a stock on hand or upon a special order to a manufacturer, and not to a mere method of collecting the money; but, however this may be, it is evident the state courts could not give it a construction which would operate as an interference with interstate commerce, and that upon this question the opinion of this court is controlling.

The cases relied upon by the state do not support its contention. In Howe Mach. Co. v. Gage, 100 U. S. 676, 25 L. ed. 754, a Connecticut corporation, manufacturing sewing machines at Bridgeport, had an agency at Nashville, Tennessee, from which an agent was sent out to sell machines. It was held that he was subject to a license tax upon 'all peddlers of sewing machines, without regard to the place of growth or produce of material or manufacture.' As it appeared that the sale was made, and wholly made, in the state of Tennessee, and apparently from a stock kept in that state, through an agent of the company, the case is not in point. This case was followed, upon a similar state of facts in Emert v. Missouri, 156 U. S. 296, 39 L. ed. 430, 5 Inters. Com. Rep. 68, 15 Sup. Ct. Rep. 367.

The case most earnestly pressed upon attention, however, is that of O'Neil v. Vermont, 144 U. S. 323, 36 L. ed. 450, 12 Sup. Ct. Rep. 693. This was a prosecution before a justice of the peace for selling, furnishing, and giving away intoxicating liquors. The defendant was a dealer in liquors at Whitehall, New York, and was in the habit of receiving at his store orders for liquors from Vermont, accompanied by a jug to contain the liquor; and the liquors, as in this case, were sent under a C. O. D. consignment.

It was held by this court that, as the only question considered by the Supreme Court in its opinion was whether the liquor was sold by O'Neil at Rutland or at Whitehall, and the court arrived at the conclusion that the completed sale was in Vermont, that this conclusion did not involve any Federal question, and the writ of error was dismissed. Mr. Justice Blatchford took express pains to say that 'no point on the commerce clause of the Constitution of the United States was taken in the county court, . . . or considered by the supreme court of Vermont.' The case was put by the supreme court of the state solely upon its police power. 'If,' said that court, 'an express company or any other carrier or person, natural or corporate, has in possession within this state an article in itself dangerous to the community, or an article intended for unlawful or criminal use within the state, it is a necessary incident of the police powers of the state that such article should be subject to seizure for the protection of the community.' It will thus be seen that the supreme court of Vermont disclaimed the decision of the very question involved in this case as to the power of the states to interfere with interstate commerce by taxation of the thing imported, and the writ of error was dismissed upon the ground that no Federal question was presented for its decision, and none was necessary to the determination of the case. Mr. Justice Field, in his dissenting opinion, thought the commerce clause of the Constitution was involved, and that the transaction was a clear interference with commerce between the states.

Upon the other hand, for the past seventy-five years, and ever since the original case of Brown v. Maryland, 12 Wheat. 419, 6 L. ed. 678, we have uniformly held that states have no power to tax directly, or by license upon the importer, goods imported from foreign countries or other states, while in their original packages, or before they have become commingled with the general property of the state, and lost their distinctive character as imports. In that case a law of Maryland required importers to take out a license before they could be permitted to sell their imported goods. That was declared to be void not only as a tax upon imports, but as an infringement upon the power of Congress to regulate commerce. The case is one of the most important ever decided by this court, and has been adhered to by a uniform series of decisions since that time.

In Robbins v. Shelby County Taxing Dist. 120 U. S. 489, 30 L. ed. 694, 1 Inters. Com. Rep. 45, 7 Sup. Ct. Rep. 592, it was declared that a tax upon commercial agents not having a business house in the state was unconstitutional as a regulation of commerce when applied to soliciting the sale of goods on behalf of individuals or firms doing business in another state, Mr. Justice Bradley remarking, apropos of what was subsequently decided in O'Neil v. Vermont, 'that the only way in which commerce between the states can be legitimately affected by state laws is when, by virtue of its police power, and its jurisdiction over persons and property within its limits, a state provides for the security of the lives, limbs, health, and comfort of persons and the protection of property; or, when it does those things which may otherwise incidentally affect commerce, such as . . . the imposition of taxes upon all property within the state, mingled with and forming part of the great mass of property therein. But in making such internal regulations a state cannot impose taxes . . . upon property imported into the state from abroad, or from another state, and not yet become part of the common mass of property therein, . . . and no regulations can be made directly affecting interstate commerce.' This case was affirmed in Asher v. Texas, 128 U. S. 129, 32 L. ed. 368, 2 Inters. Com. Rep. 241, 9 Sup. Ct. Rep. 1.

The same rule was applied in Welton v. Missouri, 91 U. S. 275, 23 L. ed. 347, and Walling v. Michigan, 116 U. S. 446, 29 L. ed. 691, 6 Sup. Ct. Rep. 454, to a statute requiring the payment of a license from persons dealing in merchandise not the growth, produce, or manufacture of the state, and requiring no such license from persons selling goods grown, produced, or manufactured within the state. In McCall v. California, 136 U. S. 104, 34 L. ed. 391, 3 Inters. Com. Rep. 181, 10 Sup. Ct. Rep. 881, a license tax imposed upon the agent of a railroad between Chicago and New York, soliciting business in San Francisco, was held to be void. To the same effect are Crutcher v. Kentucky, 141 U. S. 47, 35 L. ed. 649, 11 Sup. Ct. Rep. 851; Brennan v. Titusville, 153 U. S. 289, 38 L. ed. 719, 4 Inters. Com. Rep. 658, 14 Sup. Ct. Rep. 829, and Stockard v. Morgan, 185 U. S. 27, 46 L. ed. 785, 22 Sup. Ct. Rep. 576. Finally, in Caldwell v. North Carolina, 187 U. S. 622, 47 L. ed. 336, 23 Sup. Ct. Rep. 229, another of the same line of cases, it was held that a city ordinance imposing a license upon every person engaged in the business of selling or delivering picture frames, etc., was an interference with interstate commerce, so far as applied to picture frames made in other states, and shipped to an agent in the state of North Carolina; and that the transaction was not taken out of the protection of the commerce clause by the fact that the agent placed the pictures in their proper frames, and delivered them to the persons ordering them. Most of the prior cases are noticed in this opinion.

Indeed, the cases upon this subject are almost too numerous for citation, and the one under consideration is clearly controlled by them. The sewing machine was made and sold in another state, shipped to North Carolina in its original package for delivery to the consignee upon payment of its price. It had never become commingled with the general mass of property within the state. While technically the title of the machine may not have passed until the price was paid, the sale was actually made in Chicago, and the fact that the price was to be collected in North Carolina is too slender a thread upon which to hang an exemption of the transaction from a rule which would otherwise declare the tax to be an interference with interstate commerce.

The judgment of the Supreme Court of North Carolina is therefore reversed and the case remanded to that court for further proceeding not inconsistent with this opinion.

Mr. Justice Holmes did not participate in the decision of this case.
