Mr. Justice Van Devanter

delivered the opinion of' the Court.

This is a suit by the Great Northern Railway Company to determine conflicting claims to a small tract of land adjoining its right of way at Springbrook, "North Dakota. That company claims the tract under a grant of station grounds made by the United States to' the St. Paul, Minneapolis and Manitoba Railway, Company, and the defendants claim the same under a patent from the United States to Philander Pollock. The defendants prevailed in the trial court' and in the Supreme Court of the State. 183 N. W. 1013. A writ of certiorari brings the cáse here. 257 U. S. 629.

■ At a time when the lands in that vicinity were public lands the St. Paul, Minneapolis and Manitoba. Railway Company, being duly qualified so to do, sought and se *121 cured a right of way through the same under the Act of March 3, 1875, c. 152, 18 Stat. 482, and constructed its road within and along such right of way. At the same time and in the same way it sought and secured certain lands two miles east of the present site of Springbrook for station grounds. Afterwards it changed its station to a point adjacent to such site and proceeded to give up the original station grounds and to select others, including the tract in controversy, in their stead. It made the requisite survey of the new grounds, prepared a map thereof and on January 12, 1900, filed the map in the local land office, whence it was to be transmitted to the General Land Office and laid before the Secretary of the Interior. The map was returned to the Company for amendment in particulars not shown in the record, was amended accordingly, and on July 18, 1900, was refiled in the local land office. The local officers then transmitted it to the General Land Office, and on October 18, 1900, the Secretary of the Interior approved it “ subject to all valid existing rights.” On being advised of the Secretary’s approval, the local officers should have noted the disposal on the township plat and tract book in their office, but this was not done. The approved map and all papers relating thereto were preserved in the General Land Office in the usual way, and a certified copy of the map and of some of the papers was produced in evidence at the trial.'

On January 12,1900, when the map was first filed in the local land office, the tract in question was public land and free from any claim, but before July 18, 1900, when the map was refiled, the tract was included, with other land, in a preliminary homestead entry made by John Welo. That entry remained intact until May 13, 1901, and was then relinquished by Welo and canceled. On August 19, 1902, the tract was included, with other land, in a preliminary homestead entry made by Philander Pollock, and on June 1,1903, he released.the forty-acre'suhdi.vision con- *122 taming this tract from that entry and made another and unrelated entry, of the same subdivision. Under the latter entry a patent for the full subdivision was issued to him on February 28, 1906.

Pollock and others, whom he interested in the project, platted the greater part of the forty-acre subdivision, including the tract in question, as a townsite. The defendants purchased from them some of the lots, which, as platted, cover part of this tract..

The station grounds shown on the map approved by the Secretary of the Interior consist of a long strip of land one hundred feet wide extending along one side of the right of way at Springbrook. The tract in question is part of tha¡t strip and is in close proximity to the tracks and depot.

The rights of the St. Paul, Minneapolis & Manitoba Railway Company in the road, right of way, station grounds, etc., passed to the plaintiff, the Great Northern Railway Company, in 1907.

The Supreme Court of the State, in rejecting the plaintiff’s claim under the grant of station grounds and sustaining the defendants’ claim under the patent to Pollock, put its decision on two independent grounds. One was that when the map was refiled in the local land office, and when it was approved by the Secretary of the Interior, the tract in question was included in Welo’s preliminary homestead entry, and therefore was not subject to disposal under the Act of 1875, and that the Secretary excluded it from his approval by making the latter “ subject to all valid existing rights.” The other was that thereafter the land officers permitted Pollock to make an entry of the forty-acre subdivision containing this tract, issued to him a certificate of final entry making no reference to the railroad company’s claim and gave him a patent purporting to cover the entire subdivision, and that the defendants purchased from Pollock in good faith relying on the final certificate and patent so issued to him.

*123 The pertinent provisions of the Act of 1875 are as follows:

“That the right of way through the public lands of the United States is hereby granted to any railroad company duly organized under the laws of any State or Territory, except the District of Columbia, or by the Congress of the United States, which shall have filed with the Secretary of the Interior a copy of its articles of incorporation, and due proofs of its organization under the same, to the extent of one hundred feet on each side of the central line of said road; also the right to take, from the public lands adjacent to the line of said road, material, earth, stone, and timber necessary for the con--struction of said railroad; also ground adjacent to such right of way for station-buildings, depots,- machine shops, side-tracks, turn-outs, and water-stations, not to exceed in amount twenty acres for each station, to the extent of one station for each ten miles of its road.”

“Sec.-3. That the legislature of the proper Territory may provide for the manner in which private lands and possessory claims on the public lands of the United States may be condemned; and where such provision shall not have been made, such condemnation may be made in accordance with section three of the act entitled [an act to amend an act entitled] ‘An act to aid in the construction of a railroad and telegraph line' from the Missouri River to the Pacific Ocean, and to secure to the Government the use of the same for postal, military, and other purposes, approved July first, eighteen hundred and sixty-two,’ approved July second, eighteen hundred and sixty-four.

“ Sec. 4. That any railroad-company desiring to secure the benefits of this act, shall, within twelve months after the location- of any section of twenty miles of its road, if the same be upon surveyed lands, and, if upon unsurveyed lands, within twelve months after the survey thereof- by *124 the United States, file with the register of the land office for the district where such land is located a profile of its road; and upon approval thereof by the Secretary of the Interior the same shall be noted upon the plats in said office; and thereafter all such lands over which such right of way shall pass shall be disposed of subject to such right of way: Provided, That if any section of said road shall not be completed within five years after -the location of said section, the rights herein granted shall be forfeited as to any such uncompleted section of said road.

“Sec. 5. That this act shall not apply to any lands within the limits of any military, park, or Indian reservation, or other lands specially reserved from sale, unless such right of way shall be provided for by treaty-stipulation or by act of Congress heretofore passed.”

As with other public land laws, the Secretary of the Interior was empowered to prescribe regulations for carrying the act into effect. Such regulations were prescribed. Those in force at the times to which the controversy relates were promulgated November 4, 1898. 27 L. D. 663.

In some respects the act was loosely drafted, but through a long course of administration in the land department and many adjudications in the courts its meaning and effect have come, to be pretty well settled. Its purpose was to enhance the value and hasten the settlement of the public lands by inviting and encouraging the construction and operation of needed and convenient lines of railroad through them. Nothing was granted for private use or disposal, nor beyond what Congress deemed reasonably essential, presently or prospectively, for the quasi public uses, indicated. Because of this, the act has been regarded as requiring a more liberal construction than is accorded, to private grants or to the extensive land grants formerly made to some of the- railroads. United States v. Denver & Rio Grande Ry. Co., 150 U. S. 1, 8, *125 14. And see; Kindred v. Union Pacific R. R. Co., 225 U. S. 582, 596; Nadeau v. Union Pacific R. R. Co., 253 U. S. 442, 444. There is no provision in the act for the issue of a patent, but this does not detract from the efficacy of the grant. The approved map is intended to be the equivalent of a patent defining the grant conform-ably to the intendment of the act, Noble v. Union River Logging R. R. Co., 147 U. S. 165, and to relate back, as against intervening claims, to the date when the map was filed in the local land office for transmission through the General Land Office to the Secretary of the Interior. Stalker v. Oregon Short Line R. R. Co., 225 U. S. 142.

In the state court the defendants sought to make the point that when the company secured the station grounds two miles east of the present site of Springbrook it exhausted its right under the act and therefore could not select or take the new grounds. But the point is without merit. The company did not try to hold the original grounds and also to secure the new ones. As shown by the map, it surrendered the former and sought the latter in their stead. By approving the map the Secretary of the Interior assented to the change, — presumably because. it appeared to be one which would subserve the interests of the public as well as those of the company. It was the practice of the land department ter permit such changes. As the United States found no ground for objecting, others who had no interest in the premises at the time are not in a position to complain. Washington & Idaho R. R. Co. v. Coeur d’Alene Ry. & Nav. Co., 160 U. S. 77, 97-98.

The railway company contends that its rights under the approved map relate back to the time when the map was first filed in the local land office rather than to the time of the refiling; and, in furtherance of the contention, the company asks that we take judicial notice of the files in the General Land Office, which it says will show that *126 the amendments made in the map between the filing and refiling were so unsubstantial that there was no real alteration. But- we think the files in súch a proceeding are not within the range of judicial notice and that if there was any purpose to rely on them in this,connection they, or a certified copy of them, should have been produced in evidence at the trial. It cannot be merely assumed that the amendments were immaterial, and, in the absence of any proof of their nature and extent, the date of refiling, which was after they were made, must be taken as the time to which rights under , the approved map. relate.

We have seen that when the map was refiled, and when it was approved, the tract in question was included in Welo’s preliminary homestead entry. The Supreme Court of the State thought this prevented any right in the tract from passing to the company under the approved map, and that the words, “ subject to all valid existing rights,” were inserted in the approval to show the tract was excluded. We reach a different conclusion.

The words quoted were not peculiar to this map, but were commonly inserted in the approvals of that period. Their office was not to show that any of the land designated on the map was excluded from the grant, but to direct attention to what under the act would be true without them, — namely, that the grant was to be effective as against the United States, but was not to impair valid existing claims of settlers or others, and that to make the grant effective against such claimants théir rights should be extinguished through private negotiations or, if need be, through condemnation proceedings. See § 3 before quoted and § 2288, Rev. Stats.

That Welo had a valid existing right in virtue of his preliminary entry must be conceded. But it was only an inchoate right to acquire the title by residing on the land and otherwise complying with the homestead law for a *127 prescribed period. The title and real ownership were in the United States. Welo was under no obligation to perfect his claim. He could abandon it or relinquish it,, but could not transfer it to another. Subject only to his claim the approved map vested in the company a complete right to the tract for station purposes. He voluntarily relinquished his entry and thus put an end to his claim. Nothing then stood in the way of the company’s right. It was as if Welo’s claim never had existed.

Unlike the land grants considered in cases like Kansas Pacific Ry. Co. v. Dunmeyer, 113 U. S. 629, 639, and Hastings & Dakota R. R. Co. v. Whitney, 132 U. S. 357, 361, the Act of 1875 contains no provision whereby lands covered by homestead or similar claims when the grant attaches are excluded from it. On the - contrary, a survey of all that the act does contain shows that the grant is intended to include lands of that class, but with the qualification, plainly implied in the third section, that due compensation must be made to the claimants for their inchoate or possessory rights to make the grant operative against them. Washington & Idaho R. R. Co. v. Osborn, 160 U. S. 103, 109. An abandonment of the claims relieves the grant of the qualification. On this question the decisions have been very plain. It was before the Supreme Court of North Dakota in Jamestown & Northern R. R. Co. v. Jones, 7 N. Dak. 619, which related to a right of way over which the railroad was constructed in advance of the filing and approval of the map. The part in controversy was included in an existing preemption claim when the road was constructed and also when the map was filed and approved. Afterwards the preemption claim was abandoned. Thereupon another claimant, who had settled on the land after the construction of the road and before the filing or approval of the map, made an entry of the same tract and received a patent, — the entry papers and patent containing no exception of the right of *128 way. Two points were involved. One was whether the grant of the right of way attached as of the date when the road was constructed or as of the time when the map was filed or approved; and the other was whether the preemption claim which was in existence at all of these times operated to except the land from the grant. The decision on the latter point is- shown in the following excerpt from the opinion:

“When the act of 1875 is construed as a whole, we believe that, as against the United States, the right-of-way is. transferred, even when the land has been entered at the time the map is approved, and that, if such entry is subsequently abandoned or set aside, the grantee will enjoy an absolute easement in the land. The rights of "the railroad company* will be subject to all rights which have attached to the land before the filing and approval of the map of definite location. But, as against the United States, the grant is as effective in cases where the land has been entered as where it has not. Under any other view of the statute, the railroad company might be compelled to condemn successive rights of settlers, only to find that all its proceedings were futile, because in each case the settler’s rights were, by cancellation or abandonment, destroyed. We think that it was the purpose of congress to make the grant operative as against the government, subject only to existing rights of settlers, and that the question whether a particular piece of land was within the terms of the grant, so far as the government was concerned, was not to depend upon the freedom of that land from settlement at the time the map was approved. Under this view of the statute, a railroad company could never be required to condemn any other than existing rights.”

Other courts in the public land States have decided the question in the same way. Hamilton v. Spokane & Palouse R. R. Co., 3 Idaho, 164; Bonner v. Rio Grande *129 Southern R. R. Co., 31 Colo. 446; Alexander v. Kansas City, Ft. Scott & Memphis R. R. Co., 138 Mo. 464.

The case of Jamestown & Northern R. R. Co. v. Jones was brought here on writ of error and the railroad company’s claim to the right of way was upheld, — the decision of the Supreme Court of North Dakota being disapproved as respects the time as of which the grant attached and sustained as respects the effect of the preemption claim which was in existence at that time and afterwards abandoned. 177 U. S. 125. The opinion in the present case does not refer to that case, and we assume it was overlooked. Otherwise it doubtless would have been followed, as it should have been.

We come, then, to the ruling that the defendants purchased from Pollock in good faith relying on the certificate and patent issued to him, and so are entitled to prevail.

The claim on which Pollock received the certificate and patent was initiated more than two years after the new station grounds passed to the company under the approved map. True, the local land officers neglected to note that disposal on the township plat and tract book in their office; but this did not prejudice or affect the company’s title. The noting was required by way of continuing a practice, which had long'prevailed, of making the ■township plats and tract books in the land office of each district a fair and helpful index of all public land transactions in the district. Of course, a faithful adherence to the practice serves to prevent plural and conflicting disposals of the same lands, while a neglect of duty in that regard by the local officers sometimes, as here, results in confusing disposals. But the land department always has ruled that such a neglect of duty affords no justification for subordinating a senior to a junior claim or for making a second disposal in disregard of a prior one. Edward R. Chase, 1 L. D. 81; Goist v. Bottum, 5 L. D. 643; Edward Young, *130 9 L. D. 32; Baird v. Chapman’s Heirs, 10 L. D. 210; Linville v. Clearwaters, 11 L. D. 356. In reason the point could not be ruled otherwise, for this would mean that a patent or its equivalent, although issued after full examination of the claim by the Commissioner of the General Land Office and the Secretary of the Interior, could be thwarted or made of no avail by a subsequent omission on the part of the local land officers, — notwithstanding this Court has adjudged that such a conveyance, when regularly issued and recorded in the General Land Office, passes the title and cannot be recalled or canceled by even the Secretary of the Interior. United States v. Schurz, 102 U. S. 378. The effect of such omissions often has been considered by this Court and always has been determined along the lines just* indicated. It will suffice to refer to two of the cases. In Van Wyck v. Knevals, 106 U. S. 360, one party claimed under a land grant to a railroad company and the other under a patent issued on a cash entry. The grant was to attach when the route of the road was definitely fixed, and the Secretary of the Interior was then to withdraw from market all lands falling within the grant. A map definitely fixing the route was filed by the company with the Secretary and was accepted by him, but the intended withdrawal was not sent to the local land office for a half month or more. During that interval the cash entry was allowed and a patent certificate issued thereon. This Court sustained the claim under the grant as being first in time, and, in defining the rights which the company acquired through the filing and acceptance of the map, said, p. 367: “ No further action is required of the company to establish the route. It then became the duty of the Secretary to withdraw the lands granted from market. But if he should neglect this duty, the neglect would not impair the rights of the company, however prejudicial it might prove to others.” In Stalker v. Oregon Short Line R. R. Co., 225 U. S. 142, the railroad *131 company was relying on a grant of station grounds under the Act of 1875, which the local land officers neglected to note on their records, and the other party was claiming under a patent issued on a preemption claim. The Supreme Court of Idaho had sustained the claim of the railroad company because the map of the station grounds was filed in the local land office before the preemption claim was initiated, 14 Idaho, 371, and that decision was affirmed by this Court on the following grounds, p. 153: “ First, if we are right in holding that the grant vested in the company when the plat was approved, as of the date when filed, the failure of the officer in the district land office to properly mark the [township] plat could not operate to defeat the grant; and, secondly, the railroad company having done everything which it was required by law to do, should not be affected by the negligence of the register in not doing a duty upon which the vesting of title as against the United States did not depend.” And also, p. 154: “ We therefore conclude that the subsequent issue of a patent to the land entered by Reed [the pre-emptor] was subject to the rights of the railroad company theretofore acquired by approval of its station ground map. The patent is not an adjudication concluding the paramount right of the company, but insofar as. it included lands validly acquired theretofore, was in violation of law, and inoperative to pass title.”

When Pollock initiated his claim to-the forty-acre subdivision, which includes the tract in question, the railroad was constructed and .being operated across that subdivision, and this was true when the defendants purchased from him. Besides, the defendants understood, as- did the community in general, that the company was not claiming under Pollock and that its rights, whatever they were, were older than his. These circumstances should have put the defendants on inquiry respecting the nature and, ' extent of the company’s claim and should have prompted *132 them to make the inquiry with particular regard to the situation before Pollock’s claim was initiated, — when the subdivision was public land. So far as appears they made no inquiry, but relied on the absence of any excepting clause in Pollock’s certificate and patent, neither of which could bind the company or affect its prior rights. Among other sources of information they could have interrogated the company or its agent who was close at hand, but this was not done. In short they neglected the warning which inhered in the circumstances we have recited. The Act of 1875 was a public statute applicable to public lands in that region and some notice should have been taken of it. We have seen that it made provision for acquiring a general right of way of a uniform width and for securing additional grounds for various station purposes, — such grounds being in the nature of local extensions of the general right of way. A complete' record of the company’s proceedings under that act was kept in the usual way in the General Land Office, and it is reasonably certain that the defendants would have learned of those proceedings had they heeded the promptings of the situation in which they purchased. They therefore were chargeable - with notice of those proceedings. Brush v. Ware, 15 Pet. 93, 111.

The defendants interposed the defense of laches and also a local statute of limitations, but the Supreme Court of the State did not rule on either. Neither was applicable to the case. The tract in question was not granted for private use or disposal, but only for the quasi public uses named in the act. In other words, the company received the tract on the implied condition that it be devoted to those uses. A breach of the condition.subjects the grant to a forfeiture by the United States; but neither laches on the part of the company nor any local statute of limitations can invest individuals with any interest in the tract, or with a right to use it for private purposes, *133 without the sanction of the United States. Northern Pacific R. R. Co. v. Smith, 171 U. S. 260, 275; Northern Pacific Ry. Co. v. Townsend, 190 U. S. 267; Northern Pacific Ry. Co. v. Ely, 197 U. S. 1; Kindred v. Union Pacific R. R. Co., 225 U. S. 582, 597; Stuart v. Union Pacific R. R. Co., 227 U. S. 342, 353.

It follows that the judgment should have been for the company instead of for the defendants.

Judgment reversed.
