A rehearing was granted in this case, and after the same had been reargued the following- opinion was delivered in the June term, 1886:
Zane, C. J.:The case is now submitted on a rehearing. It is an action at law, commenced in the first district court, for the possession of two town lots in Park City, Summit county, Utah. The defendant answered, admitting possession, and alleging that the land, of which the lots in dispute were a part, was, at the time of its location, under the laws of the United States, occupied for the purposes of commerce and trade, aud was also mineral land. On the trial of the cause the court- below received in evidence a patent from the United States to one Fredrick A. Nims, the patentee, and a deed from him to the plaintiff. To their admission in evidence the defendant objected, and excepted.
The following is a copy of the patent:
“The United States of America to all whom these Presents shall come, Greeting: Whereas, in puruance of the act of Congress, April 5, 1882, entitled ‘An act for the relief of Thomas B. Valentine,’ there has been deposited in the general Land Office special certificate of location E 148, for forty acres, in favor of Thomas B. Valentine, with evidence that the same has been duly located upon the northeast quarter of the south-east quarter of section sixteen, *529township two south, of range four east, in the district of lands subject to sale at Salt Lake Oity, Utah territory, containing forty acres, according to the official plat of the survey of said land returned to the general land office by the surveyor general; the said official certificate of location having been assigned by the said Thomas B. Yalentine to Fredrick A. Nims, in whose favor said tract has been located: Now, know ye that there is therefore granted by the United States unto the said Fredrick A. Nims, as assignee as aforesaid, and to his heirs, the tract__of land above described, to have and to hold the said tract- of land, with the appurtenances thereof, unto the said Fredrick A. Nims, as assignee as aforesaid, and to his heirs and assigns, forever; subject to any agricultural, manufacturing, or other purposes, and rights to ditches and reservoirs used in connection with such water-rights as may be recognized and acknowledged by the local customs, laws, and decisions of courts and also subject to the right of the proprietor of a vein or lode to extract and remove his ore therefrom, should the same be found to penetrate or intersect the premises hereby granted, as provided by law.
“In testimbny whereof, I, Ulysses S. Grant, President of the United States of America, have caused these letters' to be patent, and the seal of the general land office to be hereto affixed.
[Seal of General Land Office.]
“Given under my hand at the city of Washington, the twenty-sixth day of February, in the year of our Lord one thousand eight hundred and seventy-seven, and’of the independence of the United States the one hundred and first.

By D. D. Cone, Secretary.
S. W. Clarke, Becorder of the General Land Office.
This patent was located under an act of Congress entitled “An act for the relief of Thomas B. Yalentine,” approved April 5,1872. It provided for the issuance of scrip to Yalentine by the commissioner, of the general land *530office, and the location thereof by Valentine, or bis legal representatives, on any “unoccupied or unappropriated public lands of the United States not mineral,” etc., and the issuance of a patent therefor.
It appears from the record that on October 12, 1875, one Brooks, a civil engineer and deputy United States mineral surveyor, made a private survey of the land described in the patent, for Nims, the patentee; that on the same day Ninis located the land by filing Valentine scrip with the register of the land office at Salt Lake City, and by leaving the same as payment therefor; that the land was not surveyed by the United States until August 25, 1876; that the land north had been surveyed by the government; and that therefrom the northeast and northwest corners of section 16 could be ascertained. Section 15 of “An act to establish a territorial government for Utah” provides “that when the lands in said territory shall be surveyed under the direction of the government of the United States preparatory to bringing the same into market, sections 16 and 36 in each township in said territory shall be, and the same are hereby, reserved for the purpose of being applied to schools,” etc.: Comp. Laws, Utah, 1876, p. 34, and section 1946, Rev. St., U. S., provides that section 16 and 36 in each township in Utah, and other territories mentioned, shall be reserved for the purpose of being applied to schools, etc. Noth withstanding, section 16, of which the land in dispute was a part, had not been surveyed at the time of the location relied upon in this case.
Did the above provisions of law vest the title to section 16 in the territory? Did they operate as an absolute reservation of the section for school purposes? Or did the legal right and title of sections 16 and 36 remain in the United States till they should be surveyed — bounded —until brought into existence as sections?
Until a survey there could be no townships, or sections 16 and 36. If the title and legal right to dispose of the land found by survey to constitute those sections continued in the federal government until surveyed, then the patent must be held valid in an action of ejectment. *531Section 16, above quoted, declares that the sections mentioned “shall be, and the same are hereby, reserved when the lands in said territory shall be surveyed under the direction of the government,” etc. This language indicates an intention to reserve when the lands shall be surveyed. It does not indicate a grant operating at once, and before the survey. The purpose of the reservation is expressed in the section — “for the purpose of being applied to schools in said territories, and in the states to be erected out of the same.” No grant in prcesenii is expressed. The lands are reserved for the purpose mentioned. The right and title remains in the government.
Section 2275, Rev. St., U. S., shows clearly that the understanding of Congress was that the title should not vest in the territory or state before the survey. It is: “Where settlements, with a view to pre-emption, have been made before the survey of the lands in the field, which are found to have been made on sections 16 or 36, those sections shall be subject to the pre-emption claim of such settler; and if they, or either of them, have been or shall be reserved or pledged for the use of schools or colleges in the state or territory in which the land lies, other lands of like quantity are appropriated in lieu of such as may be patented by pre-emptors, and other lands are also appropriated to compensate deficiencies for school purposes, where sections 16 or 36 are fractional in quantity, or where one or both are wanting, by reason of the township being fractional, or for any natural cause whatever.”
When a person settles on the public lands with a view to pre-emption, this section gives him a right to the patent, notwithstanding the land turns out, when surveyed, to be section 16 or 36, or a part thereof. The title and the right to dispose thereof is regarded as in the* United States till the survey. If not, why transfer it by patent to the pre-emptor? Those sections, or their equivalent, in other lands, are regarded as pledged for school purposes. The language of the law is “reserved or pledged.” The term “reserved” is regarded as synonymous in meaning with “pledged,” Nims having made his location before *532the land was surveyed, the title was in the United States at that time, and his title under the patent relates to the time of the location.
The case of Haydenfeldt v. Daney Gold and Silver Min. Co., 93 U. S., 634, -has been cited. In that case the plaintiff - claimed under a patent from the state of Nevada, and the defendant under a patent from the United States. The plaintiff assumed that sections 16 and 36, whether surveyed or unsurveyed, were granted to Nevada for the support of schools. The language of the Act of Congress was “that sections numbered 16 and 36, in every township, shall be, and are hereby, granted to said state for the support of common schools.” The court said: “The defendant, and those under whom it claims, occupied the land prior to the survey, and were entitled to purchase. The patent subsequently obtained from the United States relates back to the time of the original location and entry, and perfects their right to the exclusion of all adverse intervening claims;” and held that until the status of the land was fixed by a survey, and they were capable of identification, Congress reserved absolute power over them.
The defendant relied upon the case of Cooper v. Roberts, 18 How., 173. The land in dispute was a portion of section 16, which plaintiff affirmed had been appropriated by the United States to the state of Michigan for the use of schools, and his claim depended on the validity of a patent from that state issued in November, 1851. The defendant’s right depended on a patent from the United States issued in 1852. The land was surveyed in 1847. The Act of Congress admitting the state of Michigan to the Union contained the following provision: “That every section No. 16, in every township of the public lands, and, when such section has been sold or otherwise disposed of, other lands equivalent thereto, and as contiguous as may be, shall be granted to the state for the use of schools.” The court said: “We agree, that until the survey of the township, and the designation of the specific section, the right of the state vests in compact, binding, it is true, the public faith, and dependent for execution upon the political authorities. 'Courts of justice have no authority to *533mark out and define tbe land which shall be subject to the grant. But when the political authorities have performed this duty, the compact has an object upon which it can attach, and if there is no legal impediment the title of the state becomes a legal title. The jus ad rein,, by the performance of that executive act, becomes a jus in re, judicial in its nature, and under the cognizance and protection of the judicial authorities as well as the others.” The court held, in effect, that until the survey a simple obligation, rested on the federal government, and when the survey was made the state acquired a right to the particular land. The jus ad rem then became a jus in re; that until the survey the right of the state vested in compact, and at that time it vested in the state.
The case of Kissell v. St Louis Public Schools, relied upon by appellant, was a contention about certain town or village lots reserved by an Act of Congress passed in 1812 for the support of schools. On the twenty-seventh of January, 1831, another act of Congress was passed for the purpose of transferring the title of the United States (if any) remaining in the lots to the several towns and villages embraced by the act of 1812. The court held that the act of 1831 vested the title to the lands in dispute in the city of St. Louis. These lots had been so surveyed and known that they could be identified. Duncan, through whom the appellant claimed, did not enter the land till 1836, and the United States having parted with its title in 1831, such entry was void: Kissell v. St. Louis Public Schools, 18 How., 19. By the twelfth section of an Act of Congress passed March 3, 1803, entitled ‘An act regulating the grants of land, and providing for the disposal of the lands of the United States south of the state of Tennessee,’ the sixteenth section in each township was reserved and appropriated to the support of schools. Referring to the provision, the court said: “The state of Mississippi acquired a right to every sixteenth section by virtue of these acts, on the extinguishment of the Indian right of occupation, the title to which, in respect to the particular section, became vested (if vested at all) as soon as the'surveys were made and the sections designated. No patent *534was necessary, or is ever issued, for these school sections:” Gaines v. Nicholson, 9 How., 361.
On the 'trial of this case in the court below the defendant offered to prove that the land in dispute was in Park City, and its population at the time of the location, and that the land was then occupied as a town-site, and that the same was mineral land. To this evidence an objection was interposed by the plaintiff, which was sustained by the court. This ruling of the court the respondent assigned as error. W as it competent for the defendant to prove as a defense that the land Was mineral, or that it was occupied as a town-site? Was the patent conclusive of such facts in an action of ejectment?
The acts of Congress authorized the location of Yalen-tine scrip on any of the public lands unoccupied and unappropriated, and not mineral, whether surveyed or unsur-veyed. Whether the land belonged to that class termed “mineral land,” or was occupied as a town-site, were questions of fact to be determined by the land department before issuing the patent. Such determination could only be made upon evidence. The officers of the land department constitute a tribunal to determine such issues of fact, and. when decided the decision is conclusive in an action at law. The lands in dispute were the public property of the United States at the time of the location upon which the patent in question was issued. They had not been reserved from sale. They were in no reservation made by law, and the law under which the location was made authorized the same. The act authorizing the location of Yalentine scrip did not limit the right to public land of the description mentioned outside of town-sites. But if it were conceded that other statutes did make the limitation, then the question as to whether the land, or any portion of it, was a town-site — whether it was settled upon and occupied as such — was a question of fact. This question, as well as the mineral qualities and character of the land, was for the land department to determine upon evidence. This is not the case of a city with boundaries fixed by law, and recognized as such. The purpose of the evidence was to show that the land in dispute was occupied *535by a portion of tbe residents in Park City; that bouses were situated upon it in which people were living; and that the same were in such proximity as to constitute a portion of the town. The mineral characteristics of the land the defendant proposed to show by persons familiar with mineral lands, and that there were such prospects upon it.
In the case of Smelting Co. v. Kemp, the court said, speaking of the effect of the action of the officers of the land department of the United States: “In the course of their duty the officers of that department are constantly called upon to hear the testimony as to matters presented for their consideration, and to pass upon its competency, credibility, and weight. In that respect they ' exercise a judicial function, and therefore it has been held in various instances by this court that their judgment, as to matters of fact properly determined by them, is conclusive, when brought to notice in a collateral proceeding. Their judgment in such cases is, like that of other special tribunals upon matters within their exclusive jurisdiction, unassailable except by a direct proceeding for its correction or annulment.” Further along, in the same opinion, the court said, speaking of the presumptions attending the issuance of a patent: “If in issuing a patent its officers took mistaken views of the law,, or drew erroneous conclusions from the evidence, or acted from imperfect views of their duty, or even from corrupt motives, a court of law can afford no remedy to a party alleging that he is thereby aggrieved. He must resort to a court of equity for relief, and even there his complaint cannot be heard unless he connect himself with the original source of title, so as to be able to aver that his rights are injuriously affected by the existence of the patent; and he must possess such equities as will control the legal title in the patentee’s hands:” Smelting Co. v. Kemp, 104 U. S., 636.
In the case of Steel v. Smelting Co., 106 U. S., 447, referring to the land department of the United States, the court said: “That department, as we have repeatedly said, was established to supervise the various proceedings whereby a conveyance of .the title from the United States to portions of the public domain is obtained, and to see *536that the requirements of different acts of Congress are fully complied with. Necessarily, therefore, it must consider and pass upon the qualifications of the applicant, the acts lie has performed to secure the title, the nature of the land, and whether it is of the class which is open to sale. Its judgment upon these matters is that of a special tribunal, and is unassailable, except by direct proceedings for its annulment or limitation. Such has been the uniform language of this court in repeated decisions.”
The respondent cited the case of Morton v. Nebraska, 21 Wall., 660. In that case the plaintiff claimed from the "United States title to 320 acres of salt lands situated in Nebraska, under locations of military county land warrants, upon which patents had been issued. The state based its title on an alleged grant from the United States by virtue of certain statutes reserving salt springs and salines for the use of the state. In its opinion the court attached importance to the fact that the lands had been surveyed before location, and the salines noted on the field book's, though the notations were not transferred to the register’s general plats; and also to the fact .that their saline character was palpable to the eye. The court remarked that “they resembled snow-covered lakes.” The notes on the field books, and the saline on their surface, indicated their boundaries. They could be thereby identified. If so, the title passed to Nebraska before the. plaintiff’s location, and therefore the patents must have been void.
U. S. v. Carpenter was a suit in equity to vacate a patent of the United States issued to one August Chien-son to a quarter section of land, a part of the Red Pipe-stone quarry, in the county of Pipestone, in the state of Minnesota. The court held that, by treaty between the United States and the Yankton tribe of Sioux or Dacotah Indians, the whole of the reservation, embracing the quarry, was withdrawn from private entry or appropriation at the time of the location, and that the entry was therefore void. This reservation was bounded and recognized: U. S. v. Carpenter, 111 U. S., 347.
The decisions of the supreme court of the United States *537establish tlie following propositions of law: First That the various acts of Congress mentioned reserving portions of the public lands of tlie United States to the territories or states for the benefit of their people, vest the title of such lands so reserved in the territories or states when the lands are surveyed, or when they are bounded and ascertained. Until such time the obligation is exe-cutory, and the title remains in the federal government. Second. If the officers of the land department had no authority to issue the patent, for the reason that there was no law authorizing the sale of the land, or that it had been reserved from sale (being identified), or that the title was not in the United States, the patent is void. Third-As to all questions of fact which the land department is called upon to consider and pass upon before issuing the patent, the judgment of that department is unassailable, except in a direct proceeding for its annulment. Fourth. Among the questions the land department is called upon to 'consider is the character of the land, and the class to which it belongs, whether agricultural or mineral, or whether it is within a town-site. Fifth. If the land department had jurisdiction, the law conclusively presumes, in a collateral proceeding, the existence of all circumstances essential to the validity of the patent. Unless the patent is void, in view of the law, or the circumstances which the court may take judicial notice of, it must be held valid. All other essential circumstances must be presumed to have existed.
The views expressed in this opinion find support in the following cases, as well as in those above referred to: Johnson v. Towsley, 13 Wall., 72; Polk’s Lessee v. Wendal, 9 Cranch, 87; Wilcox v. Jackson, 13 Pet., 498.
Upon a careful consideration of the whole case, we find no error. The judgment pf the court below is therefore affirmed.
Powers, J., concurred. Boreman, J., having been of counsel, took no part in the decision of this case.
