    OMAECHEVARRIA v. STATE OF IDAHO.
    ERROR TO THE SUPREME COURT OP THE STATE OF IDAHO.
    No. 102.
    Argued December 20, 1917.
    Decided March 18, 1918.
    A law of Idaho (Rev. Codes, 1908, § 6872), applicable to the public domain, provides that any person having charge of sheep who allows them to graze on any range previously occupied by cattle, is guilty of a misdemeanor, and that priority of possessory right between cattle and sheep owners to any range is to be determined by the priority in the usual and customary use of it, as a cattle or sheep range. Experience, inducing this and similar laws, had, says the Supreme Court of the Stated shown that use of a range by sheep unfits • it for cattle, but not vice versa; and that segregation is essential to protect tl\e cattle industry and prevent serious breaches of the peace between cattlemen and sheepmen.
    
      Held: (1) That the police power of the State extends over the federal public domain, at least where there is no legislation by Congress on the subject.
    (2) That in segregating sheep from cattle the Idaho law was primarily designed to preserve the peace, and is not an unreasonable or arbitrary exercise of the police power.
    (3) That it does not discriminate arbitrarily and deny equal protection in giving preference to cattle owners in prior occupancy without giving a like preference to sheep owners in prior occupancy.
    (4) That, as a criminal law, it is not wanting.in due process, in failing to provide for the ascertainment of the boundaries of a “range” and ' for determining what length of time is necessary to constitute a prior occupation a “usual” one within its meaning.
    (5) That it is not in conflict with the clause in § 1 of the “act to prevent unlawful occupancy of the public lands,” c. 149, 23 Stat. 321, which prohibits the assertion of á right to the exclusive use and occupancy of any part of the public lands without claim or color of title made or acquired in good faith, etc., since that clause, as is shown by an examination of the entire act and its history, prohibits merely thé assertion of an exclusive right to use- or occupation by force, intimidation, or by what would be equivalent in effect to ar enclosure, whereas the state statute makes no grant, and, in so fai as this exclusion of sheep from certain ranges approaches' a grant-the result is incidental only, and it operates in favor of horse owners as well as cattle owners.
    (6) That the exclusion of sheep owners under certain circumstances does not interfere with any rights of a citizen of the United States, Congress not having conferred on citizens the right to graze stock on the public lands, their use for that purpose being merely by sufferance.
    27 Idaho, 797, affirmed.

   Mr. Justice Brandeis

delivered the opinion of the court.

For more than forty years the raising of cattle and sheep have been important industries in Idaho. The stock feeds in part by grazing on the public domain of the United States. This is done with the Government’s acquiescence, without the payment of compensation, and without federal regulation. Buford v. Houtz, 133 U. S. 320, 326. Experience has demonstrated, says the state court, that in arid and semi-arid regions cattle will not graze, nor can they thrive, on ranges where sheep are allowed to graze extensively; that the encroachment of sheep upon ranges previously occupied by cattle results in driving out the cattle and destroying or greatly impairing the industry; and that this, conflict of interests led to frequent and serious breaches of the peace and the loss of many lives. Efficient policing of the ranges is impossible; for the State is sparsely settled and the public domain is extensive, comprising still more than one-fourth of the land surface. To avert clashes between sheep herdsmen and the farmers who customarily allowed their few cattle to graze on the public domain near their dwellings, the territorial legislature passed in 1875 the so-called “Two Mile Limit Law.” It was enacted first as a local statute applicable to three counties,' but was extended jn 1879 and again in 1888 to additional counties, and was made a general law in 1887. After the admission of Idaho to .the Union, the statute was re-' enacted and its validity sustained by this court in Bacon v. Walker, 204 U. S. 311. To avert clashes between the sheep herdsmen and the cattle rangers, further legislation was found necessary; and in 1883 the law (now § 6872 of the Revised Codes,) was enacted which prohibits any person having charge of sheep from allowing them to graze on a range previously occupied by cattle. For violating this statute the plaintiff in error, a sheep herdsman, was convicted in the local police court and sentenced to pay a fine. The judgment was affirmed by an intermediate appellate court and also by the Supreme Court of Idaho. 27 Idaho, 797. On writ of error from this court the validity of the statute is assailed on the ground that the statute is inconsistent both with the Fourteenth Amendment and with the Act of Congress of February 25, 1885, c. 149, 23 Stat. 321, entitled, “An act to prevent unlawful occupancy of the public lands.”

First: It is urged that the statute denies rights guaranteed by the Fourteenth Amendment, namely: Privileges of citizens of the United States, in so far as it prohibits the use of the public lands by sheep owners; and equal protection of the laws, in that it gives to cattle owners a preference over sheep owners. These contentions are, in substance, the same as those made in respect to the “Two Mile Limit Law,” in Bacon v. Walker, supra; and the answer made there is. applicable here. The police power of the State extends over the federal public domain, .at least when there is no legislation by Congress on the subject. We cannot say that the measure adopted by the State is unreasonable or arbitrary. It was found that conflicts between cattle rangers and sheep herders on the public domain could be reconciled only by segregation. In national forests, where the use of land is regulated by the Federal Government, the plan of segregation is widely adopted. And it is not an arbitrary discrimination to give preference to cattle owners in prior occupancy without providing for a like preference to sheep owners in prior occupancy. For experience shows that sheep do not require protection against encroachment by cattle, and that cattle rangers are not likely to encroach upon ranges previously occupied by sheep herders. The propriety of treating sheep differently than cattle has been generally recognized. That the interest of the sheep owners of Idaho received due consideration is indicated by the fact that in 1902 they opposed the abolition by the Government of the free ranges.

Second: It is also urged that the Idaho statute, being a criminal one, is so indefinite in .its terms as to violate the guarantee-by the Fourteenth Amendment of due process of law, since it fails to provide for the ascertainment of the boundaries of a “range” or for determining what length of time is necessary to constitute a prior occupation a “usual” one within the meaning.of the act. Men familiar with range conditions and desirous of observing the law will have little difficulty in determining what is prohibited by it. Similar, expressions are common in the criminal statutes.of other States. This statute presents no greater uncertainty or difficulty, in application to necessarily varying facts, than has been repeatedly sanctioned by this court. Nash v. United States, 229 U. S. 373, 377; Miller v. Strahl, 239 U. S. 426, 434. Furthermore, any danger to sheepmen which might otherwise arise from indefiniteness, is removed by § 6314 of Revised Codes, which provides that: “In every crime or public offense there must exist a union, or joint operation, of act and intent, or criminal negligence. ”

Third: It is further contended that the statute is in direct conflict with the Act of Congress of February 25, 1885. That statute which was designed to prevent the illegal fencing of public lands, contains at the close of § 1 the following clause with which the Idaho statute is said to conflict: “and the assertion of a right to the exclusive use and occupancy of any part of the public lands of the United States in any State or any of the Territories of the United States, without claim, color of title, or asserted right as above specified as to inclosure, is likewise declared unlawful, and hereby prohibited.”

An examination of the federal act in its entirety makes it clear that what the clause quoted from § 1 sought to prohibit was merely thé assertion of an exclusive right to use or occupation by force or intimidation or by what would be equivalent in effect to an enclosure. That this was the intent of Congress is confirmedjjy the history of the act. The reports of the Secretary of the Interior upon whose recommendation the act was introduced, the reports of the committees of Congress, and the debates thereon .indicate that this alone was the evil sought to be remedied, and to such action only does its prohibition appear to-' have been applied in practice. Although Idaho had, by statute, excluded sheep from portions of the public domain since 1875 — no reference to the fact has been found in the discussion which preceded and followed the enactment of the federal law, nor does any reference seem to have been made to the'legislation of other States which likewise excluded sheep, under certain circumstances, from parts of the public domain. And no case has been found in which it was even urged that these state statutes were in conflict with this act of Congress.

. The Idaho statute makes no attempt to grant a right to use public lands. McGinnis v. Friedman, 2 Idaho, 393. The State, acting in the exercise of its police power, merely excludes sheep from certain ranges under certain circumstances. Like the forcible entry and detainer act of Washington, which was held in Denee v. Ankeny, ante-, 208, not to conflict with the homestead laws, the Idaho statute was enacted primarily to prevent breaches of the peace. The incidental protection which it thereby affords to cattle owners does not purport to secure to any-of them, or to cattle owners collectively, "the exclusive use and occupancy of any part of the public lands.” For every range from which sheep are excluded remains open not only to all cattle, but also to horses, of which there are many in Idaho. This exclusion of sheep owners-under certain circumstances does not interfere with any. rights of a citizen of the United States. Congress has not conferred upon citizens the right to graze stock, upon the public lands. The Government has merely suffered the lands to be so used. Buford v. Houtz, supra. It is because the citizen possesses no such right that it was held by this court that the Secretary of Agriculture might, in the exercise of his general power to regulate forest reserves, exclude sheep and cattle therefrom. United States v. Grimaud, 220 U. S. 506; Light v. United States, 220 U. S. 523.

All the objections urged against the validity of the statute arc unsound. The judgment of the Supreme Court of Idaho is

Affirmed.
