delivered the opinion of the court.
This is a suit in equity, brought, according to the practice obtaining in Missouri, to settle the conflicting claims of the parties, arising from their respective patents, to a fractional section of land comprising thirty-seven acres and two-fifths of an acre,-situated in that State. The plaintiffs assert title to the premises under, a patent issued to William M. McPherson by the governor of the State, bearing date on the 27th of February, 1850, purporting to .be for lands selected under the eighth section of the act of Congress of Sept. 4, 1841, entitled “ An act to appropriate the proceeds of the sales of the public *332 lands, and to grant pre-emption rights ” (5 Stat. 458); and the defendants claim title to the premises under a patent of the United States, bearing date on the 21st of July, 1866, issued to the heirs of Thomas Chartrand upon an alleged pre-emption right acquired by a settlement of their ancestor.
The eighth section of the act of Sept. 4, 1841, declared that there should be granted to each State specified in its first section — and among them was the State of Missouri — five hundred thousand acres of land for purposes of internal improvemént-, the selection of the land in the several States to be made within their respective limits, in such manner as the legislatures thereof should direct, but in parcels-conformably to sectional divisions and subdivisions of the - public surveys, and of not less than three hundred and twenty acres in each, from any public land except such as was or might be reserved from- sale by any law of Congress or proclamation of the President.' Several acts were passed by the legislature of Missouri for the selection and disposition of the land thus granted. One of them, passed on the 10th. of March, 1849 (Laws of Missouri of 1849, p. 64), authorized the governor of the State to, dispose, at private sale, of sо much of the land as then remained to be selected, and to issue to the purchasers certificates empowering them to locate the quantity purchased, in conformity with the act of Congress. The purchasers were to inform the governor of the lands selected, and he was to notify the Secretary of the' Treasury that the selections were made for the State; and, if approved by the - secretary, patents were to issue tо the purchasers;
Where the land selected in any instance contained less than three hundred and twenty acres, the governor was required, upon the request of the purchaser and upon' payment for the full amount, to relinquish the surplus to the United' States. Of the certificates thus issued, one was held by William M, McPherson; and under it a. selection was made by him óf the premises in controversy. • Of this selection the governor of the State informed the Secretary оf the Treasury on the 15th of December, 1849, and requested his approval of it; at the same time relinquishing to the United States the surplus between the amount selected and three hundred and twenty acres. At *333 that time the supervision of the land-office had been transferred from the Secretary of the Treasury to the Secretary of the Interior, whose department was created in March of that year. The selection of McPherson was accоrdingly brought to the latter’s attention, and was approved by him on the 17th of January following; subject, however, to any rights which may have existed at the time the selection was made known to the land-officers by the agent of the State. On the 27th of February following, a patent of ■ the State of Missouri for the premises was issued to McPherson by the governor. Upon the title thus conferred the' plaintiffs repose, and ask judgment in their favor.
In considering the validity of this title, the first' quеstion for solution is, whether the premises were then open to selection by the State; for whether the eighth section of the act of 1841 be construed as conferring a grant' in prcesenti, operating to vest the title in the State upon the selection of the land pursuant to its directions, notwithstanding the words of grant used are in the future tense, — in that respect resembling the grant of the State of North Carolina to General Greene, which was the subject of consideration by this court in the ease of Rutherford v. Greene's Heirs, reported'in the 2d of Wheaton, — • or whether the section be considered as giving only the promise of a grant, and therefore requiring further legislation, or' further action in some form of the government, to vest the title of the land- selected in the State, as held, or rather implied, by the decision in the case of Foley v. Harrison, reported in .the 15th of .Howard, the same result must follow if the land were not at the time open to selection. If not thus open,- the .whole proceeding on the part of McPherson and the governor of the State to appropriate the land was ineffectual for any purpose. That the land was not thus open, we think. there is no doubt. The land was then' claimed as part of the commons of Carondelet. The villages of St.- Louis and Carondelet, on the acquisition of Louisiana in' 1803 and for many years previously, claimed as сommons certain lands adjoining their respective settlements; Those of St. Louis extended south of the village of that name, those of Carondelet to the north of its village; and a well-known line was generally re.cog *334 nized as the boundary separating the commons of the two villages. ' That line commenced on the bank of the Mississippi at what is known as Sugar-loaf Mound, about four miles south of the settlement of St. Louis, and two miles north of that of .Carondelеt, and ran westerly to the common fields of Carondelet. It was contended, in the controversy which subsequently arose between the cities of St. Louis and Carondelet, that this line. had been surveyed and marked by Soulard, a Spanish surveyor, previous to 1800, by order of the lieutenant-governor of the ’ upper province of Louisiana. Be that as it may, it is clear that from the acquisition of the country until June 13, 1812, the land south of this line was claimed and used by the inhabitants оf Carondelet as within their commons. On that day Congress passed an act confirming to the inhabitants of these villages their claims to their common lands. 2 Stat. 748. The act was a present operative grant of all the interest of the United States in the property used by the inhabitants of the villages as their commons; but it did not refer to the line mentioned, or designate any boundary of the commons, but left that to be established by proof of previous possessiоn and use. The act at the ^ame time made it the duty of the deputy-surveyor of the territory to survey the out-boundary lines of the villages so as to include the commons respectively belonging to them, and make out plats of the surveys, and transmit them to the surveyor-general, by whom copies were to be forwarded to the Commissioner of the General Land-Office and the recorder of land-titles.- No survey appears to have been made, as here directed, of the out-boundary line of the village of Carondelet, until the year 1816; but its inhabitants claimed under the act the ownership and title, of the land as part of their commons, up to the line mentioned on the north, as the same had been claimed and used by them previously. In 1816 or 1817, Elias Rector, a deputy-surveyor, under instructions from his superior, made a survey of the commons, running the upper line about a mile below the line alleged to have beеn established by Soulard. Some years after-wards (in 1834), another deputy-surveyor, by the name of Joseph C. Brown, was ordered by the surveyor-general to retrace and mark anew the lines of this survey, and, connect *335 them with the surveys of adjoining public lands and private claims. This was accordingly done by him; and it would seem by various proceedings of the authorities of Carondelet that the survey thus retraced was at one time acquiesced in by them as a determinаtion of the boundaries of their commons. They had a copy of it framed for the benefit of the town, and they introduced it in several suits.with different parties as evidence of the extent of their claim. But at another time they denied the correctness of its northern line, which they insisted should be coincident with that alleged to have been run by Soulard. When St. Louis, in 1836, proceeded to subdivide her commons into lots down to the line of the survey, they gave notice, through a committee, that the lands below the alleged Soulard line were claimed as part of their commons; and, in 1855, Carondelet entered a suit against St. Louis for the possession of those lands. In the mean time, the matter remained undetermined in the land department at Washington until the 23d of February of that year. During this period, the Commissioner of the General Land-Office repeátedly informed the local .land-officers that the tract was reserved from sale because it was claimed as part of the Carondelet commons, and on that ground their refusal to receive proofs of settlement from parties seeking to acquire a right of pre-emption was approved; and appropriate entries stating such reservation were made in the books of those officers. At one time (January, 1852) the Secretary of the Interior decided to have a new survey of the commons, аnd gave orders to that effect. The surveyor-general for Missouri having asked instructions as to the manner of the survey, and stating that, in his opinion, the new survey should include the land in controversy, the"secretary then in office, the successor of the one who had.ordered a new survey, re-examined the whole subject, and recalled the direction for a new survey made by his predecessor, and held that as the surveys of 1816 and 1834 had been executed by competent authority.and approved, and were for years acquiesced in by the inhabitants of Carondelet, both they and the government of. the United States were estopped and concluded by them; and that, in consequence, the survey of 1816, as retraced in 1834, should be sustained, excluding therefrom *336 a tract -which had been reserved for a military post. This was the final determination of the boundaries of the Carondelet commons by that departmеnt of the government to which the supervision of surveys of public grants was intrusted. A few days before this determination was announced, the suit mentioned, of the city of Carondelet against the city of St. Louis, was commenced to obtain possession of. the lands below the Soulard line, over a portion of which the St. Louis commons had been extended. That suit, was finally disposed of by the judgment of this court in March, 1862, affirming.that of the Supreme Court of the State, to the еffect that both the government and Carondelet were concluded by the surveys stated.
The act of 1812 contemplated that the out-boundary line of ■the village would be surveyed so as to include the commons claimed, in accordance with the possession of the inhabitants previous to 1803, and not arbitrarily, according to the caprice of the surveyor; and any line run by him was subject, like all other surveys of public grants, to the supervision and aрproval of the land department at Washington. Until surveyed, and the survey was thus approved, the land claimed by Carondelet was, by force of the act requiring the survey and the establishment of the boundaries, necessarily reserved from sale. It was thus reserved to be appropriated in satisfaction of the claim, if that should be ultimately sustained. Whenéver in the disposition of the public lands any action is required to be taken by an officer of' the land dеpartment, all proceedings tending to •defeat such action are impliedly inhibited. The allowance of selections by the States, or of pre-emptions by individuals, of lands which might be included within grants to • others, might interfere, and in many instances would interfere, with the accomplishment of the purposes of the government. A sale, is as much prohibited by a law of Congress, when to allow it would defeat the object of that law, as though the inhibition were in direct terms declared; The general rule of the land department is, and from the commencement of the government has been, to hold as excluded from sale or pre-emption lands which might, in the execution of the laws of Congress, fall within grants to others; and therefore, in this case, until it was decided by the final determination of the Secretary of the Inte *337 rior or of the Supreme Court- of the United States whether the northern line of the commons was that run, as alleged,, by Soulard previous to 1800, or that retraced by Brown in 1834, the land between those lines, embracing the premises in controversy, was legally reserved from sale, and, consequently, from any selection by the State as part of its five hundred thousand acres granted by the act of Sept. 4,1841.
But there is another view of this case which is equally fatal to the claim of the plaintiffs. If the land outside of the survey .as retraced by Brown in 1834 could be deemed public, land, open to selection by the State of Missouri from the time' the survey was returned to the land-office, in St. Louis, it was equally open from that date to settlement, and consequent preemption by settlers. The same limitation which was imposed by law upon settlement was imposed by law upon the selection of the State. In either case the land must have been surveyed, and thus offered for sale or settlement.. The party who takes the initiatory step in such cases, if followed up to patent, is deemed to have acquired the better, right as against, others to the premises. The patent which is afterwards issued relates back to the date of the initiatory act, and cuts off all intervening claimants. Thus the patent upon a State selection takes effect as of' the time when the selection is made and reported to the land-office; and the patent upon a pre-emptiоn settlement takes effect from the time of the settlement as disclosed in the declaratory statement or proofs of the settler to the register of the local land-office. The action of the State and of the settler must, of course, in some way be brought officially to the notice of the officers of the government having in their custody the records and other evidences of title to the property of the United States beforе their respective claims to priority of right can be recognized. But it was not intended by the eighth section of the act of 1841, in authorizing , the State to make selections of land, to interfere with the operation of the other provisions of that act regulating the system of settlement and preemption. The two modes of acquiring title to land from the United States were not in conflict with each other. ■ Both were to have full operation, that one controlling in a particular case under which the first initiatory step was had.
*338
Nor is there any thing in this view in conflict with- the doctrines announced in
Frisbie
v.
Whitney,
But whilst, according to these, decisions, no vested right as against the United States is acquired until all the prerequisites for the acquisition of the title have been complied with, parties may, as against each other, acquire a right to be preferred in the purchase or other acquisition of the land, when the.United States have determined to sell or donate the property. In all such cases, the first in time in the commencement of proceedings fоr the acquisition pf the title, when the same are regularly followed up, is deemed to be the first in right. So in this case, Chartrand, the ancestor, by his previous settlement in 1835 *339 upon the premises in controversy, and residence with his family, and application to prove his settlement and enter the land, obtained a better right to the premises, ‘ under the law then existing, than that acquired by McPherson by his subsequent State selection in 1849. His right thus .initiated could not be prejudiced by the refusal of the local officers to receive his proofs upon the declaration that the land was then reserved, if, in point of fact, the reservation had then ceased. The reservation was asserted, as already mentioned, on the ground that the land was then claimed as a part of the commons of Carondelet. So soon as the claim was held to be invalid to this extent by the decision of this court in March, 1862, the heirs of Chartrand prеsented anew their claim to pre-emption, founded upon the settlement of their ancestor. Thé act of Congress of March 3,1853,10 Stat. 244, provided that any settler who had settled or might thereafter settle on lands previously reserved on account of claims under French, Spanish, or other grants, which had been or should thereafter be declared invalid by the Supreme Court of the United States, should be entitled to all the rights of preemption granted bythe act of Sept. 4,1841, after the lands were released from reservation, in the same manner as if no reservation had existed. With the decision declaring the invalidity of the claim to the land in controversy, all obstacles previously interposed to the presentation of the claim of the heirs of Chartrand, and the proofs to establish it, were removed. According to the decisions in Frisbie v. Whitney and the Yo-Semite Valley Case, Congress might then have withdrawn the land from settlement and pre-emption, and granted it directly to the State of Missouri, or reserved it from sale for public purposes, and no vested right in Chartrand or his heirs as against the United States woxild have been, invaded by its action; but, having allowed by its. subsisting legislation the acquisition of a right of preference as against others to the earliest settler or his heirs, the way was free to the prosecution of the claim of the heirs.
If the matter were open for our consideration, we might perhaps doubt as to the sufficiency of the .proofs presented by the heirs of Chartrand to the officers of the land department to establish a right o.f pre-emption by virtue of the settlement and *340 proceedings of their ancestor, or by virtue of their own settlement. Those proofs were, however, considered sufficient by the register of the local land-office, by the Commissioner of the General Land-Office.on appeal from the register, and by the Secretary of the Interior on appeal from the commissioner. There is no evidence of any fraud or imposition practised upon them, or that they erred in the construction of any law applicable to the case. It is only contended that they erred in their deductions' from' the proofs presented;'and for errors of that kind, where the parties interested had notice of the proceedings before the land department, and were permitted to contest the same, as in th, present case, the courts can furnish no remedy.. The officers! of the land department are specially designated by law to receive, consider, and pass upon proofs presented with respect to settlements upon the public lands, with a view'to secure rights of pre-emption. If they err in the construction of the law applicable to any case, or if fraud is practised upon them,'or they themselves are chargeable with fraudulent practices, theiry rulings may be reviewed and annulled bythe courts when a jbontroversy arises between private parties founded upon their decisions; but, for mere errors of judgment tip on the weight of evidence in a contested case before them, the only remedy is by' appeal from one- officer to another of the department, and perhaрs, under spepial circumstances, to the ¿resident. It may also be, and probably is, true that the courts may furnish, in proper cases, relief to a party where new evidence is discovered, which, if possessed and presented at the time, would have changed the action of the land-officers; but, except in such cases, the ruling of the department on disputed questions of fact made in a contested case, must be taken, when that ruling is collaterally assailed, as conclusive. '
In this case, therefore, we cannot inquire into the correctness of the ruling of the land department upon the evidence presented of the settlement of Chartrand, the ancestor, of of his heirs. / It follows that the patent issued by the United. States, taking effect as of the date of such settlement, overrides the patent of the State of Missouri to McPherson, even admitting, that, but for the settlement, the land w;ould have been open to selection by the State. ' Decree affirmed.
