v.
JONES, STATE CHEMIST OF THE STATE OF INDIANA.
No. 68.
Supreme Court of United States.
Argued January 18, 1912.
Decided June 7, 1912.
APPEAL FROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE DISTRICT OF INDIANA.
*513 Mr. M.H. Boutelle for appellant.
Mr. Edwin Corr, with whom Mr. Thomas M. Honan, Attorney General of the State of Indiana, was on the brief, for appellee.
*519 MR. JUSTICE HUGHES, after making the above statement, delivered the opinion of the court.
The principal contention in support of this appeal is that the statute of Indiana (Acts 1907, chapter 206), the provisions of which have been set forth, is an unconstitutional interference with the complainant's right to engage in interstate commerce.
A preliminary question arises with respect to the jurisdiction of this court, by reason of the allegation of the bill that the complainant's product is not a "concentrated commercial feeding stuff" within the true meaning of the act, and that so interpreted the statute would not apply. But it was also alleged that the State Chemist, who was authorized to enforce the statute, had construed it to be applicable to the commodity, which is commercially known as "International Stock Food;" and thus charged by the officer with the duty of obedience, the complainant in his bill challenged the constitutionality of the legislation. The grounds for the attack were not found in the conclusions reached by the officer, as to the nature of the article, in administering an act otherwise conceded to be valid (Arbuckle v. Blackburn, 191 U.S. 405, 414), but in the provisions of the statute itself as applied to the articles within its purview while in the course of interstate commerce. A general demurrer, for want of equity, was sustained, and in view of the substantial character of the contention the case must be regarded as one in which the law of a State is claimed to be in contravention of the Constitution of the United States. Act of March 3, 1891, 26 Stat. 826, c. 517, § 5; Penn Mutual Life Insurance Co. v. Austin, 168 U.S. 685, 694; Loeb v. Columbia Township Trustees, 179 U.S. 472, 478; Lampasas v. Bell, 180 U.S. 276, 282.
It is said that the complainant is not entitled to invoke the constitutional protection, in that he fails to show injury. *520 Southern Railway Co. v. King, 217 U.S. 524, 534. The argument rests upon the averment in the bill that his sales were made at Minneapolis, the goods "to be delivered free on board of cars" at that point, "and delivered to purchasers and consumers within the State of Indiana in the original unbroken packages, freight being paid thereon by the consumers and purchasers." In answer, it must again be said that "commerce among the State is not a technical legal conception, but a practical one, drawn from the course of business." Swift & Co. v. United States, 196 U.S. 375, 398; Rearick v. Pennsylvania, 203 U.S. 507, 512. It clearly appears from the bill that the complainant was engaged in dealing with purchasers in another State. His product manufactured in Minnesota was, in pursuance of his contracts of sale, to be delivered to carriers for transportation to the purchasers in Indiana. This was interstate commerce, in the freedom of which from any unconstitutional burden the complainant had a direct interest. The protection accorded to this commerce by the Federal Constitution extended to the sale by the receiver of the goods in the original packages. Leisy v. Hardin, 135 U.S. 100; In re Rahrer, 140 U.S. 545, 559, 560; Plumley v. Massachusetts, 155 U.S. 461, 473; Vance v. Vandercook Co. (No. 1), 170 U.S. 438, 444, 445; Schollenberger v. Pennsylvania, 171 U.S. 1, 22-25; Heyman v. Southern Railway Co., 203 U.S. 270, 276. An attack upon this right of the importing purchasers to sell in the original packages bought from the complainant, not only would be to their prejudice, but inevitably would inflict injury upon the complainant by reducing his interstate sales, a result to be avoided only through his compliance with the act by filing the statement and affixing to his goods the labels it required. According to the bill, the State Chemist had threatened the complainant that in default of such compliance he would cause the arrest and prosecution of every person dealing in the *521 article within the State and had distributed broadcast throughout the State warning circulars. If the statute of Indiana, as applied to sales by importing purchasers in the original packages, constitutes an unwarrantable interference with interstate commerce in the complainant's product, he had standing to complain, and was entitled to relief against enforcement by the defendant of the illegal demands. Scott v. Donald, 165 U.S. 107, 112; Ex parte Young, 209 U.S. 123, 159, 160; Ludwig v. Western Union Telegraph Co., 216 U.S. 146; Hopkins v. Clemson College, 221 U.S. 636, 643-645; Philadelphia Co. v. Stimson, 223 U.S. 605, 620, 621.
We are thus brought to the examination of the statute. The question of its constitutional validity may be considered in two aspects, (1) independently of the operation and effect of the act of Congress of June 30, 1906, c. 3915 (34 Stat. 768), known as "The Food and Drugs Act," and (2) in the light of this Federal enactment.
First. The statute relates to the sale of various sorts of food, for domestic animals, embraced in the term "concentrated commercial feeding stuff" as defined in the act. It requires the filing of a statement and a sworn certificate, the affixing of a label bearing certain information, and a stamp.
By § 1 it is provided, in substance, that before any such feeding stuff is sold, or offered for sale, in Indiana, "the manufacturer, importer, dealer, agent or person," selling or offering it, shall file with the State Chemist a statement that he desires to sell the feeding stuff, and also a sworn certificate, for registration, stating (a) the name of the manufacturer, (b) the location of the principal office of the manufacturer, (c) the name, brand or trade-mark under which the article will be sold, (d) the ingredients from which it is compounded, and (e) the minimum percentage of crude fat and crude protein, allowing one per cent. of nitrogen to equal six and twenty-five hundredths *522 per cent. of protein, and the maximum percentage of crude fiber which the manufacturer or person offering the article for sale guarantees it to contain; these constituents to be determined by the methods recommended by the association of official agricultural chemists of the United States. The State Chemist is to register the facts set forth in the certificate in a permanent record (§ 3).
Section 2 provides that there shall be affixed to every package or sample of the article a tag or label which shall be accepted as a guarantee of the manufacturer, importer, dealer or agent and shall have plainly printed thereon (a) the number of net pounds of feeding stuff in the package, (b) the name, brand or trade-mark under which it is sold, (c) the name of the manufacturer, (d) the location of the principal office of the manufacturer, and (e) the guaranteed analysis stating the minimum percentage of crude fat and crude protein determined as described in § 1, and the ingredients from which the article is compounded.
A stamp purchased from the State Chemist, showing that the article has been registered and that the inspection tax has been paid, is to be affixed for each one hundred pounds or fraction thereof, special provision being made for the delivery of an equivalent number of stamps on sale in bulk. By an amendment of 1909, stamps are to be issued by the State Chemist to cover twenty-five, fifty and one hundred pounds (Acts 1909, chapter 46, p. 106). He is not required to sell stamps in less amount than to the value of five dollars, or multiples thereof, for any one feeding stuff, or to register any certificate unless accompanied by an order and fees for stamps to the amount of five dollars, or some multiple of that sum (§ 3). Sworn statements are to be filed annually of the number of net pounds of each brand of feeding stuff sold or offered for sale in the State (§ 4).
The price of the stamps under the original act was one *523 dollar per hundred; but by the amendment of 1909 (supra) the charge was made eighty cents per hundred, for stamps to cover one hundred pounds, and forty cents and twenty cents respectively for stamps to cover fifty and twenty-five pounds. The fees received are to be paid into the treasury of the Indiana Agricultural Experiment Station and expended "in meeting all necessary expenses in carrying out the provisions of this act, including the employment of inspectors, chemists, expenses in procuring samples, printing bulletins giving the results of the work of feeding stuff inspection, as provided for by this act, and for any other expenses of said Indiana agricultural experiment station, as authorized by law." A classified report of the receipts and expenditures is to be made to the Governor of the State annually (§ 5).
Any one selling, or offering for sale, any feeding stuff which has not been registered, and labeled and stamped as required by the act, or which is found by an analysis made by the State Chemist or under his direction to contain "a smaller percentage of crude fat or crude protein than the minimum guarantee," or is "labelled with a false or inaccurate guarantee," and any one who adulterates any feeding stuff "with foreign mineral matter or other foreign substance, such as rice hulls, chaff, mill sweepings," etc., "or other materials of less or of little or no feeding value without plainly stating on the label hereinbefore described, the kind and amount of such mixture," or who adulterates with any substance injurious to the health of domestic animals, or alters the State Chemist's stamp, or uses it a second time, or fails to make the sworn statement as to annual sales as required, is guilty of a misdemeanor and is subject to fine (§ 6).
The State Chemist and his deputies are empowered to procure from any lot or package of the described feeding stuffs offered for sale or found in Indiana a quantity not exceeding two pounds, to be drawn during reasonable *524 business hours, or in the presence of the owner or his representatives (§ 7), and it is made a misdemeanor to interfere with such inspection and sampling (§ 8). He is also authorized to prescribe and enforce regulations as he may deem necessary to carry the act into effect; and he may refuse "the registration of any feeding stuff under a name which would be misleading as to the materials of which it is made, or when the percentage of crude fiber is above or the percentage of crude fat or crude protein below the standards adopted for concentrated commercial feeding stuffs."
The evident purpose of the statute is to prevent fraud and imposition in the sale of food for domestic animals, a matter of great importance to the people of the State. Its requirements were directed to that end, and they were not unreasonable. It was not aimed at interstate commerce, but without discrimination sought to promote fair dealing in the described articles of food. The practice of selling feeding stuffs under general descriptions gave opportunity for abuses which the legislature of Indiana determined to correct, and to safeguard against deception it required a disclosure of the ingredients contained in the composition. The bill complains of the injury to manufacturers if they are forced to reveal their secret formulas and processes. We need not here express an opinion upon this question, in the breadth suggested, as the statute does not compel a disclosure of formulas or manner of combination. It does demand a statement of the ingredients, and also of the minimum percentage of crude fat and crude protein and of the maximum percentage of crude fiber, a requirement of obvious propriety in connection with substances purveyed as feeding stuffs.
The State cannot, under cover of exerting its police powers, undertake what amounts essentially to a regulation of interstate commerce, or impose a direct burden upon that commerce. Railroad Co. v. Husen, 95 U.S. *525 465, 475; Walling v. Michigan, 116 U.S. 446; Bowman v. Chicago &c. Ry. Co., 125 U.S. 465; Leisy v. Hardin, 135 U.S. 100; Minnesota v. Barber, 136 U.S. 313; Brimmer v. Rebman, 138 U.S. 78; Scott v. Donald, 165 U.S. 58; Schollenberger v. Pennsylvania, 171 U.S. 1, 13; Houston & Texas Central R.R. Co. v. Mayes, 201 U.S. 321; Atlantic Coast Line v. Wharton, 207 U.S. 328; Adams Express Co. v. Kentucky, 214 U.S. 218. But when the local police regulation has real relation to the suitable protection of the people of the State, and is reasonable in its requirements, it is not invalid because it may incidentally affect interstate commerce, provided it does not conflict with legislation enacted by Congress pursuant to its constitutional authority. Plumley v. Massachusetts, 155 U.S. 461; Hennington v. Georgia, 163 U.S. 299, 317; N.Y., N.H. & H. Ry. Co. v. New York, 165 U.S. 628; Chicago, M. & St. P. Ry. Co. v. Solan, 169 U.S. 133; Missouri, Kansas & Texas Ry. Co. v. Haber, 169 U.S. 613; Patapsco Guano Co. v. North Carolina, 171 U.S. 345; Reid v. Colorado, 187 U.S. 137; Pennsylvania R.R. Co. v. Hughes, 191 U.S. 477; Crossman v. Lurman, 192 U.S. 189; McLean v. Denver & Rio Grande R.R. Co., 203 U.S. 38, 50; Asbell v. Kansas, 209 U.S. 251, 254-256; Chicago, R.I. & P. Ry. Co. v. Arkansas, 219 U.S. 453.
In Plumley v. Massachusetts, a law of that Commonwealth was sustained which had been passed "to prevent deception in the manufacture and sale of imitation butter." The article, for the sale of which the plaintiff in error was convicted in the state court, had been received by him from the manufacturers in Illinois, as their agent, and had been sold in Massachusetts in the original package. The court said (supra, pp. 468, 472), referring to the purpose and effect of the statute: "He is only forbidden to practice, in such matters, a fraud upon the general public. The statute seeks to suppress false pretences and to promote fair dealing in the sale of an article of food. It *526 compels the sale of oleomargarine for what it really is, by preventing its sale for what it is not. Can it be that the Constitution of the United States secures to any one the privilege of manufacturing and selling an article of food in such manner as to induce the mass of people to believe that they are buying something which, in fact, is wholly different from that which is offered for sale? Does the freedom of commerce among the States demand a recognition of the right to practice a deception upon the public in the sale of any articles, even those that may have become the subject of trade in different parts of the country? . . . Such legislation may, indeed, indirectly or incidentally affect trade in such products transported from one State to another State. But that circumstance does not show that laws of the character alluded to are inconsistent with the power of Congress to regulate commerce among the States."
In Patapsco Guano Co. v. North Carolina, supra, the court had before it a statute of North Carolina relating to fertilizing materials. It provided: "Every bag, barrel or other package of such fertilizers or fertilizing materials as above designated offered for sale in this State shall have thereon plainly printed a label or stamp, a copy of which shall be filed with the Commissioner of Agriculture, together with a true and faithful sample of the fertilizer or fertilizing material which it is proposed to sell, . . . and the said label or stamp shall truly set forth the name, location and trade-mark of the manufacturer; also the chemical composition of the contents of such package, and the real percentage of any of the following ingredients asserted to be present, to wit, soluble and precipitated phosphoric acid, which shall not be less than eight per cent; soluble potassa, which shall not be less than one per cent; ammonia, which shall not be less than two per cent, or its equivalent in nitrogen; together with the date of its analyzation, and that the requirements of the law have *527 been complied with; and any such fertilizer as shall be ascertained by analysis not to contain the ingredients and percentage set forth as above provided shall be liable to seizure and condemnation." A charge of twenty-five cents per ton on such materials was laid for the purpose of defraying the expenses connected with the inspection; and the department of agriculture was authorized to establish an experiment station and to employ an analyst, whose duty it was to analyze such fertilizers and products as might be required by the department and to aid so far as practicable in suppressing fraud in their sale.
The court upheld the statute, saying (supra, p. 357): "Whenever inspection laws act on the subject before it becomes an article of commerce they are confessedly valid, and also when, although operating on articles brought from one State into another, they provide for inspection in the exercise of that power of self-protection commonly called the police power." After referring to the decision in Plumley v. Massachusetts, supra, the court continued (pp. 358, 361): "Where the subject is of wide importance to the community, the consequences of fraudulent practices generally injurious, and the suppression of such frauds matter of public concern, it is within the protective power of the State to intervene. Laws providing for the inspection and grading of flour, the inspection and regulation of weights and measures, the weighing of coal on public scales, and the like, are all competent exercises of that power, and it is not perceived why the prevention of deception in the adulteration of fertilizers does not fall within its scope. . . . The act of January 21, 1891, must be regarded, then, as an act providing for the inspection of fertilizers and fertilizing materials in order to prevent the practice of imposition on the people of the State, and the charge of twenty-five cents per ton as intended merely to defray the cost of such inspection. It being competent for the State to pass laws of this character, does the requirement *528 of inspection and payment of its cost bring the act into collision with the commercial power vested in Congress? Clearly this cannot be so as to foreign commerce, for clause two of section ten of article one expressly recognizes the validity of state inspection laws, and allows the collection of the amounts necessary for their execution; and we think the same principle must apply to interstate commerce. In any view, the effect on that commerce is indirect and incidental, and `the Constitution of the United States does not secure to any one the privilege of defrauding the public.'"
It cannot be doubted that, within the principle of these decisions, and of the others above cited, the State of Indiana  assuming for the present that there was no conflict with Federal legislation  was entitled, in the exercise of its police power, to require the disclosure of the ingredients contained in the feeding stuffs offered for sale in the State, and to provide for their inspection and analysis. The provisions for the filing of a certificate, for registration and for labels, were merely incidental to these requirements and were appropriate means for accomplishing the legitimate purpose of the act. It is said that the statute permits the State, through its officials, to set up arbitrary standards governing conditions of manufacture. But it does not appear that any arbitrary standard has been set up, or that there has been any attempt to enforce one against the complainant. (See Western Union Telegraph Co. v. Richmond, 224 U.S. 160, 168.) The complainant has declined to file the statement and to affix the labels containing the disclosure of ingredients for which the statute provides, and instead he resorts to this suit.
The contention is made that the statute is a disguised revenue measure, but on a review of its provisions we find no warrant for such a characterization of it. The bill sets forth no facts whatever to show that the charge for stamps is unreasonable in its relation to the cost of inspection, *529 and certainly it cannot be said that aught appears "to justify the imputation of bad faith and change the character of the act." Patapsco Guano Co. v. North Carolina, supra; McLean v. Denver & Rio Grande R.R. Co., supra; Red "C" Oil Co. v. North Carolina, 222 U.S. 380, 393. With respect to the requirement of an advance payment for stamps, to the value of five dollars, to accompany the certificate, we need not say more than that the complainant is plainly not prejudiced, in view of the alleged extent of his sales.
Second. The question remains whether the statute of Indiana is in conflict with the act of Congress known as the Food and Drugs Act of June 30, 1906 (34 Stat. 768, c. 3915). For the former, so far as it affects interstate commerce even indirectly and incidentally, can have no validity if repugnant to the Federal regulation. Reid v. Colorado, 187 U.S. 137, 146, 147; Asbell v. Kansas, 209 U.S. 251, 256, 257; Northern Pacific Ry. Co. v. Washington, 222 U.S. 370, 378; Southern Ry. Co. v. Reid, 222 U.S. 424, 436.
The object of the Food and Drugs Act is to prevent adulteration and misbranding, as therein defined. It prohibits the introduction into any State from any other State "of any article of food or drugs which is adulterated or misbranded, within the meaning of this act." The purpose is to keep such articles "out of the channels of interstate commerce, or, if they enter such commerce, to condemn them while being transported or when they have reached their destinations, provided they remain unloaded, unsold or in original unbroken packages." Hipolite Egg Co. v. United States, 220 U.S. 45, 54. To determine the scope of the act with respect to feeding stuffs we must examine its definitions of the adulteration and misbranding of food, the term "food" including "all articles used for food, drink, confectionery, or condiment by man or other animals, whether simple, mixed or compound" *530 (§ 6). These definitions are found in §§ 7 and 8, which are set forth in the margin.[1]
*531 It will be observed that in its enumeration of the acts, which constitute a violation of the statute, Congress has not included the failure to disclose the ingredients of the article, save in specific instances where, for example, morphine, opium, cocaine, or other substances particularly mentioned, are present. It is provided that the article "for the purposes of this Act" shall be deemed to be misbranded if the package or label bear any statement, *532 design or device regarding it or the ingredients or substances it contains, which shall be false or misleading (§ 8). But this does not cover the entire ground. It is one thing to make a false or misleading statement regarding the article or its ingredients, and it may be quite another to give no information as to what the ingredients are. As is well known, products may be sold, and in case of so-called proprietary articles frequently are sold, under trade names which do not reveal the ingredients of the composition and the proprietors refrain from revealing them. Moreover, in defining what shall be adulteration or misbranding for the purposes of the Federal act, it is provided that mixtures or compounds known as articles of food under their own distinctive names, not taking or imitating the distinctive name of another article, which do not contain "any added poisonous or deleterious ingredients" shall not be deemed to be adulterated or misbranded if the name be accompanied on the same label or brand with a statement of the place of manufacture (§ 8).
Congress has thus limited the scope of its prohibitions. It has not included that at which the Indiana statute aims. Can it be said that Congress, nevertheless, has denied to the State, with respect to the feeding stuffs coming from another State and sold in the original packages, the power the State otherwise would have to prevent imposition upon the public by making a reasonable and non-discriminatory provision for the disclosure of ingredients, and for inspection and analysis? If there be such denial it is not to be found in any express declaration to that effect. Undoubtedly Congress, by virtue of its paramount authority over interstate commerce, might have said that such goods should be free from the incidental effect of a state law enacted for these purposes. But it did not so declare. There is a proviso in the section defining misbranding for the purposes of the act that "nothing in this Act shall be construed" as requiring manufacturers of *533 proprietary foods which contain no unwholesome added ingredient to disclose their trade formulas "except in so far as the provisions of this Act may require to secure freedom from adulteration or misbranding" (§ 8). We have already noted the limitations of the provisions referred to. And it is clear that this proviso merely relates to the interpretation of the requirements of the act, and does not enlarge its purview or establish a rule as to matters which lie outside its prohibitions.
Is, then, a denial to the State of the exercise of its power for the purposes in question necessarily implied in the Federal statute? For when the question is whether a Federal act overrides a state law, the entire scheme of the statute must of course be considered and that which needs must be implied is of no less force than that which is expressed. If the purpose of the act cannot otherwise be accomplished  if its operation within its chosen field else must be frustrated and its provisions be refused their natural effect  the state law must yield to the regulation of Congress within the sphere of its delegated power. Texas & Pacific Ry. Co. v. Abilene Cotton Oil Co., 204 U.S. 426; Northern Pacific Ry. Co. v. Washington, supra; Southern Ry. Co. v. Reid, supra.
But the intent to supersede the exercise by the State of its police power as to matters not covered by the Federal legislation is not to be inferred from the mere fact that Congress has seen fit to circumscribe its regulation and to occupy a limited field. In other words, such intent is not to be implied unless the act of Congress fairly interpreted is in actual conflict with the law of the State. This principle has had abundant illustration. Chicago &c. Ry. Co. v. Solan, 169 U.S. 133; Missouri, Kansas & Texas Ry. Co. v. Haber, 169 U.S. 613; Reid v. Colorado, 187 U.S. 137; Pennsylvania R.R. Co. v. Hughes, 191 U.S. 477; Crossman v. Lurman, 192 U.S. 189; Asbell v. Kansas, 209 U.S. 251; Northern Pacific Ry. Co. v. Washington, 222 *534 U.S. 370, 379; Southern Ry. Co. v. Reid, 222 U.S. 424, 442.
In Missouri, Kansas & Texas Ry. Co. v. Haber, supra, the Supreme Court of Kansas had affirmed a judgment against the railway company for damages caused by its having brought into the State certain cattle alleged to have been affected with Texas fever which was communicated to the cattle of the plaintiff. The recovery was based upon a statute of Kansas which made actionable the driving or transporting into the State of cattle which were liable to communicate the fever. It was contended that the act of Congress of May 29, 1884, c. 60 (23 Stat. 31), known as the Animal Industry Act, together with the act of March 3, 1891, c. 544 (26 Stat. 1044), appropriating money to carry out its provisions, and § 5258 of the Revised Statutes, covered substantially the whole subject of the transportation from one State to another State of live stock capable of imparting contagious disease, and therefore that the State of Kansas had no authority to deal in any form with that subject. The act of 1884 provided for the establishment of a bureau of animal industry, for the appointment of a staff to investigate the condition of domestic animals and for report upon the means to be adopted to guard against the spread of disease. Regulations were to be prepared by the commissioner of agriculture and certified to the executive authority of each State and Territory. Special investigation was to be made for the protection of foreign commerce and the Secretary of the Treasury was to establish such regulations as might be required concerning exportation. It was provided that no railroad company within the United States, nor the owners or masters of any vessel should receive for transportation, or transport, from one State to another any live stock affected with any communicable disease, nor should any one deliver for such transportation, or drive on foot or transport in private conveyance from *535 one State to another any live stock knowing them to be so affected. It was made the duty of the commissioner of agriculture to notify the proper officials or agents of transportation companies doing business in any infected locality of the existence of contagion; and the operators of railroads, or the owners or custodians of live stock within such infected district, who should knowingly violate the provisions of the act were to be guilty of a misdemeanor punishable by fine or imprisonment.
The court held that this Federal legislation did not override the statute of the State; that the latter created a civil liability as to which the Animal Industry Act of Congress had not made provision. The court said (supra, pp. 623, 624):
"May not these statutory provisions stand without obstructing or embarrassing the execution of the act of Congress? This question must of course be determined with reference to the settled rule that a statute enacted in execution of a reserved power of the State is not to be regarded as inconsistent with an act of Congress passed in the execution of a clear power under the Constitution, unless the repugnance or conflict is so direct and positive that the two acts cannot be reconciled or stand together. Sinnot v. Davenport, 22 How. 227, 243. . . . Whether a corporation transporting, or the person causing to be transported from one State to another cattle of the class specified in the Kansas statute, should be liable in a civil action for any damages sustained by the owners of domestic cattle by reason of the introduction into their State of such diseased cattle, is a subject about which the Animal Industry Act did not make any provision. That act does not declare that the regulations established by the Department of Agriculture should have the effect to exempt from civil liability one who, but for such regulations, would have been liable either under the general principles of law or under some state enactment for damages arising *536 out of the introduction into that State of cattle so affected. And, as will be seen from the regulations prescribed by the Secretary of Agriculture, that officer did not assume to give protection to any one against such liability."
In Reid v. Colorado, supra, the question arose under a statute of Colorado which had been passed to prevent the introduction into the State of diseased animals. The statute made it a misdemeanor for any one to bring into the State between April 1 and November 1 any cattle or horses from a State, Territory or county south of the 36th parallel of north latitude, unless they had been held at some place north of that parallel at least ninety days prior to importation, or unless the owner or person in charge should procure from the State Veterinary Sanitary Board a certificate, or bill of health, to the effect that the cattle or horses were free from all infectious or contagious diseases and had not been exposed thereto at any time within the preceding ninety days. The expense of any inspection in connection therewith was to be paid by the owner.
The plaintiff in error had been convicted of bringing cattle into the State in violation of the statute. There was no proof in the case that the particular cattle had any infectious or contagious disease, but it did appear that they were brought from Texas, south of the 36th parallel, without being held or inspected as the statute required. Its provisions were ignored altogether as invalid legislation. When the plaintiff in error refused assent to the state inspection he showed to the authorities a certificate signed by an assistant inspector of the Federal bureau of animal industry who certified that he had carefully inspected the cattle in Texas and found them free from communicable disease. It was insisted that the statute of Colorado was in conflict with the Animal Industry Act of Congress, but the court sustained the state law for the *537 reason that, although the two statutes related to the same general subject, they did not cover the same ground and were not inconsistent with each other.
The court thus emphasized the general principle involved (supra, p. 148): "It should never be held that Congress intends to supersede or by its legislation suspend the exercise of the police powers of the States, even when it may do so, unless its purpose to effect that result is clearly manifested. This court has said  and the principle has been often reaffirmed  that `in the application of this principle of supremacy of an act of Congress in a case where the state law is but the exercise of a reserved power, the repugnance or conflict should be direct and positive, so that the two acts could not be reconciled or consistently stand together.'" And in the course of its review of the subjects embraced in the Federal legislation the court said (pp. 149, 150):
"Still another subject covered by the act is the driving on foot or transporting from one State or Territory into another State or Territory, or from any State into the District of Columbia, or from the District into any State, of any live stock known to be affected with any contagious, infectious or communicable disease. But this provision does not cover the entire subject of the transporting or shipping of diseased live stock from one State to another. The owner of such stock, when bringing them into another State, may not know them to be diseased; but they may, in fact, be diseased, or the circumstances may be such as fairly to authorize the State into which they are about to be brought to take such precautionary measures as will reasonably guard its own domestic animals against danger from contagious, infectious or communicable diseases. The act of Congress left the State free to cover that field by such regulations as it deemed appropriate, and which only incidentally affected the freedom of interstate commerce. Congress went no farther than to make it an *538 offence against the United States for any one knowingly to take or send from one State or Territory to another State or Territory, or into the District of Columbia, or from the District into any State, live stock affected with infectious or communicable disease. The Animal Industry Act did not make it an offence against the United States to send from one State into another live stock which the shipper did not know were diseased. The offence charged upon the defendant in the state court was not the introduction into Colorado of cattle that he knew to be diseased. He was charged with having brought his cattle into Colorado from certain counties in Texas, south of the 36th parallel of north latitude, without said cattle having been held at some place north of said parallel of latitude for at least the time required prior to their being brought into Colorado, and without having procured from the State Veterinary Sanitary Board a certificate or bill of health to the effect that his cattle  in fact  were free from all infectious or contagious diseases, and had not been exposed at any time within ninety days prior thereto to any such diseases, but had declined to procure such certificate or have the inspection required by the statute. His knowledge as to the actual condition of the cattle was of no consequence under the state enactment or under the charge made.
"Our conclusion is that the statute of Colorado as here involved does not cover the same ground as the act of Congress and therefore is not inconsistent with that act; and its constitutionality is not to be questioned unless it be in violation of the Constitution of the United States, independently of any legislation by Congress."
In Asbell v. Kansas, supra, the plaintiff in error had been convicted under a statute of the State of Kansas which made it a misdemeanor to transport cattle into the State from any point south of the south line of the State, except for immediate slaughter, without having first *539 caused them to be inspected and passed as healthy by the proper state officials or by the bureau of animal industry of the Interior Department of the United States. The court held that the statute was a valid exercise of the power of the State unless it were in conflict with the act of Congress. It appeared that since the decision in Reid v. Colorado, supra, Congress had provided that where an inspector of the bureau of animal industry had issued a certificate that he had inspected live stock and found them free from communicable disease they should be transported into any State or Territory without further inspection or the exaction of fees of any kind, except such as might be required by the Secretary of Agriculture. But as the law of Kansas recognized the Federal certificate, a conflict with the act of Congress was avoided, and hence the conviction under the state law was sustained.
Applying these established principles to the present case, no ground appears for denying validity to the statute of Indiana. That State has determined that it is necessary in order to secure proper protection from deception that purchasers of the described feeding stuffs should be suitably informed of what they are buying and has made reasonable provision for disclosure of ingredients by certificate and label, and for inspection and analysis. The requirements, the enforcement of which the bill seeks to enjoin, are not in any way in conflict with the provisions of the Federal act. They may be sustained without impairing in the slightest degree its operation and effect. There is no question here of conflicting standards, or of opposition of state to Federal authority. It follows that the complainant's bill in this aspect of the case was without equity.
Other objections urged by the bill to the validity of the statute, save so far as they may be deemed to involve the questions that have already been considered, have not been pressed in argument and need not be discussed. *540 Recurring to the contention that the product of the complainant is not within the statute, it is evident that, assuming the validity of the enactment, the complainant showed no ground for resorting to equity, as the nature of the composition must be determined according to the fact in the course of due proceedings for that purpose.
The demurrer was properly sustained.
Affirmed.
