¶1delivered the opinion of the court.
¶2Action for damages for trespass on land. - On October 5, 1910, the plaintiff became the owner by purchase from the Northern Pacific Railway Company of seven and a half sections of land in Lewis and Clark county, lying within the limits of the grant originally made to the Northern Pacific Railroad Company. These sections connect with and adjoin other lands owned, respectively, by the plaintiff and the defendants. The plaintiff and the defendants are engaged in the business of buying, raising and selling sheep, the defendants being copartners. Up to the time of plaintiff’s purchase he and the defendants had been accustomed to use these lands, and also the intervening government sections, as pasture for their sheep whenever it suited their convenience, all of them being uninclosed. Defendants knew of plaintiff’s purchase, and that his purpose in making it was to provide pasture for his sheep. Soon after the purchase, plaintiff warned them not to use the lands so purchased. On May 17, 1911, he brought an action, charging that between October 5, 1910, and May 12, 1911, the defendants, without his consent and without right, had herded and pastured their sheep upon these lands, with the result that the grass and herbage thereon were entirely eaten off and destroyed, to his damage in the sum of $2,000, and demanding judgment for that amount and for costs. On June 23, 1911, he brought a second action, the purpose’being to recover damages for trespasses alleged to have been committed between May 13 and June 19. In his complaint he alleged that the conduct of defendants was malicious. He also alleged that the defendants were constantly repeating their acts of trespass and were threatening to continue them, and that the damage thus accruing and threatened could not be adequately compensated in damages. He demanded judgment for $1,250 damages, with costs, and a perpetual injunction. In the first action, the defendant tendered issue by a denial of all the material allegations of wrongdoing contained in the complaint. In the second, besides tendering a like issue, they alleged, in sub*229stance, that thé action had not been brought in good faith to recover damages for wrongs committed by the defendants, but that the plaintiff had acquired lands to which he claims title, for the sole purpose of compelling the defendants to remove their flocks from the> portion of the range which they had heretofore been accustomed to use, and to desist from pasturing them upon the even-numbered government sections, which are open to the use of all stockmen alike for grazing purposes. Upon these allegations there was issue by reply. The two causes were by stipulation of counsel consolidated and tried as one. The plaintiff recovered a verdict for $1,200 as compensatory and $100 as punitive damages. Judgment was entered for this amount, with eosts, and also for a perpetual injunction. From the judgment and from the order denying their motion for a new trial the defendants have appealed. They assign insufficiency of the evidence to justify the verdict, errors in rulings of the court upon questions of evidence, and in submitting and refusing certain instructions to the jury. They also contend that the verdict is excessive, and that the injunction feature of the judgment is too broad.
¶31. We shall not attempt to set out the evidence and examine it in detail. There was no controversy but that the plaintiff became the owner of the seven and one-half sections of land described in the complaint at the time alleged. As to whether the defendants herded their sheep on them at all, or did so through inadvertence because of their lack of acquaintance with the boundary lines, or because of their indisposition to ascertain their location, or, finally, whether they did so purposely and maliciously, the evidence is in hopeless conflict. It was
¶42. The witness Wills, called for the purpose of testifying as to the value of the pasturage, stated, in substance, that he had been working with sheep for ten or twelve years, herding, tending
¶5*2313. Such of the other rulings upon questions of evidence as affect the merits of this controversy will be disposed of by a determination of the fundamental question of law which is presented by the theory of the case adopted by the court in submitting instructions to the jury. It is comprehended in the inquiry: By what rule must members of the community be governed with reference to uninclosed .lands held by private ownership, when they seek to avail themselves of the use, for the pasturage of their stock, of the adjoining and unappropriated sections belonging to the federal government? To what extent may they trespass upon, or make use of, the adjoining private lands in order to gain access to the public lands ? Must they at their peril ascertain the boundary lines and limit their encroachments upon the adjoining lands entirely to a reasonable way of necessity for crossing them, or may they use them at will without regard to private ownership in them, until such time as the owner so definitely marks their boundaries as to give notice of their location? In instructing the jury, the court adopted the theory that one who seeks to make use of uninclosed public lands must at his peril ascertain the boundaries of adjoining private owners, and that, if the circumstances show that he has herded or willfully driven his stock upon such adjoining lands, he is liable to the owner for such damage as he has caused him.
¶6The privilege to use the unappropriated public lands for pasturage has become so confirmed by the custom of the people, recognized and acquiesced in by the federal government (Buford v. Houtz, 133 U. S. 320, 33 L. Ed, 618, 10 Sup. Ct. Rep. 305), that it is everywhere regarded as a valuable right. The value of agricultural and other lands held by private ownership in many localities is often greater because of adjacent areas of great extent, outside of government reservations, which up to the present time have not been found useful for any other than grazing purposes. Those who can conveniently reach them can and do use them by common right at great profit.
¶7Let it be assumed that because of the acquiescence of the Northern Pacific Railway Company in the use of its lands by the plaintiff and defendants they had acquired a license to so use *232them up to the time of plaintiff’s purchase; yet the purchase'of them by the plaintiff,'with the knowledge of defendants, operated as a revocation of defendants ’ license, and from that time forward plaintiff was entitled to the exclusive use of them, just as other lands owned by him.
¶8Under the common-law rule, the owner of animals was required to keep them within Ms own inclosures, and if they were permitted to stray upon the lands of another, though such other lands were not inclosed, the owner was held liable in trespass for such damage as they did. The ideal invisible boundary, existing only in contemplation of law, was a legal fence sufficient to protect the owner in the exclusive right of occupation and use, a right which is an attribute of private ownership. (3 Blackstone’s Commentaries, 209, 211; 1 Addison on Torts, sec. 375; Bileu v. Paisley, 18 Or. 47, 4 L. R. A. 840, and notes, 21 Pac. 934; 2 Cyc. 392; Monroe v. Cannon, 24 Mont. 316, 81 Am. St. Rep. 439, 61 Pac. 863.) The conditions prevailing in the public land states early led to a modification of this rule. Under statutory provisions in many, if not all, of them the owner of animals may permit them to run at large. He is not liable for damage done by them upon lands of another, unless the owner of such other lands has them inclosed by a legal fence. The provisions of our own statutes on the subject are found in sections 2082 and 2090 of the Revised Codes, and apply to all domestic animals, except those enumerated in section 8836, which the owner must keep within his own inclosures under the common-law rule. But these provisions have no application to animals in charge of a herder. They were construed in Monroe v. Cannon, supra,and it was held that where the defendant caused his sheep to be herded upon lands which he knew belonged to the plaintiff, though the lands were not inclosed, he was liable for the damage done by them. This decision in effect declared that the purpose of the legislation was to condone trespasses committed by animals lawfully running at large, and that the common-law rule is left otherwise unchanged. It has uniformly been recognized as establishing the rule of decision in this state. (Beinhorn v. Griswold, 27 Mont. 79, 94 Am. St. *233Rep. 818, 59 L. R. A. 771, 69 Pac. 557; Clemmons v. Gillette, 33 Mont. 321, 114 Am. St. Rep. 814, 83 Pac. 879; Musselshell Cattle Co. v. Woolfolk, 34 Mont. 126, 85 Pac. 874; Rea Bros. Sheep Co. v. Rudi, ante, p. 149, 127 Pac. 85.) The result of
¶9But counsel insist that the court erred in refusing to give to the jury an instruction embodying the provisions of 'sections 8474 and 8475 of the Revised Codes. Section 8474 declares: “It shall be unlawful for any person or persons to willfully drive, or cause to be driven, any livestock held in herd, on or over any field, ranch property or valid claim in process of title under any of the land laws of the United States, or under lease from the state of Montana, whether the same be fenced or not; provided, that any lands so owned, or under process of title, or under lease, and not fenced, shall be clearly defined by suitable *234monuments or stakes, and plow furrows, with printed or written notices indicating the lands so held.” Section 8475 provides for the imposition of a fine when, upon complaint of the owner, a defendant is found guilty of any of the acts declared unlawful in section 8474. These provisions do not affect the question at issue in this case. They merely declare unlawful and punish as a misdemeanor the driving or herding of animals upon the uninclosed lands of another when the boundaries are marked as therein provided. They do not, either in terms or by implication, annul the rule of civil liability for trespasses falling within the principle of the decision in Monroe v. Gannon, and reaffirmed in the other cases cited supra.
¶10The defendants assign error upon the refusal by the court to give the following instruction: “(7) The court instructs the jury that if you find from the evidence that the plaintiff is the owner of any or all of the lands described in his complaints, and that said lands are so situated as to inclose a part of the public domain, whereby such part of the public domain is rendered inaccessible to those having occasion to pasture or graze their flocks or herds thereon, then in such event the defendants would have the right to cross said lands of the plaintiff in a reasonably prudent manner in order to obtain access to said domain for grazing purposes. And if you find from the evidence in this case that the defendants did drive sheep across some of the lands of the plaintiff, in order to reach those portions, if any, of the public domain, which were surrounded by the lands of the plaintiff, then in such event the plaintiff could not recover for any damages so occasioned.”
¶11The rule is well settled that, where one person grants to another
¶12The grant by the federal government to the railroad company, so far as the question at issue is concerned, does not differ from a grant by one private person to another. It is impossible to gain access to the even-numbered sections belonging to the government except by going over some portion of the odd sections.

¶16The cause is remanded to the district court with directions: (1) To grant the defendants a new trial unless within thirty days after the filing of the remittitur in the district court, the plaintiff shall consent in writing that the judgment, so far as it awards compensatory damages, be reduced to $600. If such consent is given, the judgment shall be modified accordingly as of the date of its original entry, and, together with the order denying the motion for a new trial, will stand affirmed. The part of the judgment relating to costs in the district court, and to punitive damages, is not to be disturbed. (2) To 'set aside the injunction, and, unless the parties can agree upon ways to be used by the defendants over plaintiff’s lands for access to the government sections, to hear evidence and ascertain such ways in accordance with thé suggestions made in this opinion, *238and to issue an injunction limiting the rights of the defendants accordingly. The defendants shall recover the cost of printing their brief and their filing fee in this court.
