MR. JUSTICE BROWN, after making the foregoing statement, delivered the opinion of the court.

This case arose upon the following state of facts: Nelson Morris Co., citizens of Illinois, were engaged, in the city of Chicago, in the business of packing meats for sale and consumption, and also had a place of business in Atlanta, Georgia, where they sold their products at wholesale, having in their employ several clerks and helpers, one of whom was the petitioner, who was employed as chief clerk and manager at a salary of $25 per week. The firm did not have anywhere within the State of Georgia any packing house for slaughtering, dressing, curing, packing or manufacturing the products of any animals for food or commercial use, but took orders, which were transmitted and filled at Chicago, the meats sent to Atlanta and there distributed in pursuance of such orders. Certain meats were also shipped from Chicago to Atlanta without a previous sale or contract to sell. These were stored in the Atlanta house of the firm in the original packages, and were kept and held for sale, in the ordinary course of trade, as domestic business. They were offered for sale to such customers as might require them, and until sold were stored and preserved and remained the property of the firm.

1. It was admitted by the Supreme Court of Georgia in its opinion, and by both parties hereto, that a tax upon the seller of goods is a tax upon the goods themselves, Brown v. Maryland, 12 Wheat. 419; Welton v. Missouri, 91 U.S. 275; and that a tax upon goods sold in another State, delivered to a common carrier and consigned to the purchaser in the State of Georgia, was an illegal interference with interstate commerce. Caldwell v. North Carolina, 187 U.S. 622; Norfolk c. Ry. Co. v. Sims, 191 U.S. 441; Stone v. State, 117 Ga. 292. It was therefore held that the tax, so far as applied to meats sold in Chicago and shipped to the petitioner in Georgia for distribution, could not be supported; but that so far as the petitioner was engaged in the business of selling directly to customers in Atlanta, he was engaged in carrying on an independent business as a wholesale dealer, and was liable to the tax.

This decision was correct. In carrying on the domestic business, petitioner was indistinguishable from the ordinary butcher, who slaughters cattle and sells their carcasses, and in principle it made no difference that the cattle were slaughtered in Chicago and their carcasses sent to Atlanta for sale and consumption in the ordinary course of trade. Upon arrival there they became a part of the taxable property of the State. It made no difference whence they came and to whom they were ultimately sold, or whether the domestic and interstate business were carried on in the same or different buildings. In this particular the case is covered by that of Brown v. Houston, 114 U.S. 622, wherein it was held that coal mined in Pennsylvania and sent by water to New Orleans, to be sold in open market there on account of the owners in Pennsylvania, became intermingled with the general property of the State, and liable to taxation under its laws, although it might have been after arrival sold from the vessel on which the transportation was made, without being landed, and for the purpose of being taken out of the country on a vessel bound to a foreign port. The same principle was applied in Emert v. Missouri, 156 U.S. 296, in which a license tax upon peddlers of goods, which made no distinction between residents and products of the State and of those of other States, was sustained. To the same effect is Machine Company v. Gage, 100 U.S. 676.

The case is readily distinguishable from that of Crutcher v. Kentucky, 141 U.S. 47, wherein a state law requiring a license from agencies of foreign express companies was held to be a regulation of interstate commerce, so far as applied to a corporation of another State engaged in interstate business, although as incidental thereto it did some local business by carrying goods from one point to another in the State of Kentucky. The court observed that while the local business was probably quite as much for the accommodation of the people of the State as for the advantage of the company, this did not obviate the objection to the tax; that the regulations as to license and capital stock were imposed as conditions on the companies carrying on the business of interstate commerce, which was manifestly the principal object of its organization. "These regulations are clearly a burden and a restriction upon the commerce. Whether intended as such or not they operate as such. But taxes or license fees in good faith imposed exclusively on express business carried on wholly within the State would be open to no such objection."

The same doctrine was applied to telegraph companies in Leloup v. Port of Mobile, 127 U.S. 640, wherein a general license tax upon the telegraph company was held to affect its entire business, interstate as well as domestic or internal, and was unconstitutional. This case, however, must be read in connection with Postal Telegraph Cable Co. v. Charleston, 153 U.S. 692, wherein we held that a license tax upon a telegraph company on business done exclusively within the State, and not including any business done to or from points without the State, and not including any business done for the Government of the United States, was an exercise of the police power, and not an interference with interstate commerce. In line with this case is that of Ratterman v. Western Union Tel. Company, 127 U.S. 411, in which a percentage tax assessed upon receipts of telegraph companies partly derived from interstate commerce and partly from commerce within the State, and which were capable of separation, but were returned and assessed in gross, and without separation or apportionment, was held invalid in proportion to the extent that such receipts were derived from interstate commerce, but valid as applied to receipts from messages within the State. To the same effect is Western Union Tel. Co. v. Alabama, 132 U.S. 472.

So, if the stock of a transportation company be taxed by taking as a basis of assessment such proportion of its capital stock as the number of miles of railroad over which its cars are run within the State bear to the whole number of miles over which its cars are run throughout the United States, such assessment does not impinge upon the power of Congress. Pullman's Car Company v. Pennsylvania, 141 U.S. 18. The case is still simpler, if the tax be imposed in terms upon the domestic commerce, seeing that the corporation is free to abandon the business taxed if it sees fit. Pullman Company v. Adams, 189 U.S. 420; Allen v. Pullman Company, 191 U.S. 171.

The only difficulty in this case arises from the fact that the tax is laid not in terms upon the domestic business, nor upon the gross receipts or profits which might be apportioned between interstate and domestic business, but is a gross sum imposed upon the managing agent of packing houses, regardless of the fact that the greater portion of the business may be interstate in its character. This contingency, however, is met by the case of Osborne v. Florida, 164 U.S. 650, wherein a license tax imposed upon express companies doing business in Florida had been construed by the Supreme Court of that State as applying solely to business of the company done within the State, and not to its interstate business. Accepting this construction of the state statute as in reality part of the statute itself, we held that it did not in any way violate the Federal Constitution. The statute was sustained, notwithstanding the fact that ninety-five per cent of the business was interstate in its character, and only five per cent consisted of carrying goods and freight between points within the State of Florida. Crutcher v. Kentucky, 141 U.S. 47, was distinguished as one which prohibited the agent of a foreign express company from carrying on business at all in that State without first obtaining a license from the State. Said the court: "It has never been held, however, that when the business of the company which is wholly within the State, is but (not) a mere incident to its interstate business, such fact would furnish any obstacle to the valid taxation by the State of the business of the company which is entirely local. So long as the regulation as to the license or taxation does not refer to and is not imposed upon the business of the company which is interstate, there is no interference with that commerce by the state statute."

So, in the case under consideration it was expressly held by the Supreme Court of Georgia that that part of the Nelson Morris Company's business, which consisted in shipping goods to Atlanta to fill orders previously received, the goods being delivered in accordance with such orders, was interstate commerce, not subject to taxation within the State, and that, so far as applied to that business, the tax was void. Accepting this construction of the Supreme Court, we think the act, so far as applied to domestic business, is valid. The record does not show what proportion of such business is interstate and what proportion is domestic, although it is conceded that most of the business is interstate in its character. If the amount of domestic business were purely nominal, as, for instance, if the consignee of a shipment made in Chicago upon an order filled there, refused the goods shipped, and the only way of disposing of them was by sales at Atlanta, this might be held to be strictly incidental to an interstate business, and in reality a part of it, as we held in Crutcher v. Kentucky, 141 U.S. 47; but if the agent carried on a definite, though a minor, part of his business in the State by the sales of meat there, he would not escape the payment of the tax, since the greater or less magnitude of the business cuts no figure in the imposition of the tax. There could be no doubt whatever that, if the agent carried on his interstate and domestic business in two distinct establishments, one would be subject and the other would not be subject to the tax, and in our view it makes no difference that the two branches of business are carried on in the same establishment. The burden of proof was clearly upon the plaintiff to show that the domestic business was a mere incident to the interstate business.

2. The act in question does not deny to the petitioner the equal protection of the laws, as the tax is imposed alike upon the managing agent both of domestic and of foreign houses. In its first opinion in this case the Supreme Court held that the tax was a vocation or occupation tax, and that it was not designed to apply to every agent or employe of the company, but only to the managing or superintending agent, who is the alter ego of the principal by whom he is employed. There is no discrimination in favor of the agents of domestic houses, and, while we may suspect that the act was primarily intended to apply to agents of ultra state houses, there is no discrimination upon the face of the act, and none, so far as the record shows, upon its practical administration. As we have frequently held, the State has the right to classify occupations and to impose different taxes upon different occupations. Such has been constantly the practice of Congress under the internal revenue laws. Cook v. Marshall County, 196 U.S. 261, 275. What the necessity is for such tax, and upon what occupations it shall be imposed, as well as the amount of the imposition, are exclusively within the control of the state legislature. So long as there is no discrimination against citizens of other States, the amount and necessity of the tax are not open to criticism here.

3. The argument that the tax impairs the obligation of a contract between the petitioner and Nelson Morris Company is hardly worthy of serious consideration. The power of taxation overrides any agreement of an employe to serve for a specific sum. His contract remains entirely undisturbed. There was no stipulation for an employment for a definite period; and if there were, it is inconceivable that the State should lose this right of taxation by the fact that the party taxed had entered into an engagement with his employer for a definite period. The tax is an incident to the business, and probably might under the terms of their contract be charged up against the employer as one of the necessary expenses of carrying it on.

The judgment of the Supreme Court of Georgia is

Affirmed.
