The relation of the parties to the cause of action is the same in this court as in the state courts, and we will refer to plaintiff in error as plaintiff and to the defendants in error as defendants.

The pleadings in the case are exceedingly voluminous and equally so are the findings of fact. It is enough for out purpose to say that the city of Lewiston, state of Idaho, was entered as a town site under § 2387 of the Revised Statutes (U. S. Comp. Stat. 1901, p. 1457), hereinafter quoted, and a patent was issued by the United States to the mayor of the city in trust for the occupants of the lands conveyed. In pursuance of the trust, the mayor executed conveyances to the predecessors in title of plaintiff and defendants. The rights derived through these deeds, and the occupation of the land preceding and subsequent to them, and the effect of a survey made by one E. P. True, hereinafter referred to, and the plat thereof filed by him, constitute the questions in the case. Plaintiff seeks by this suit to enjoin defendants from encroaching on D street, as laid down on said plat, by certain buildings which, it is alleged, they proposed to erect. It is prayed, besides, that the buildings, if erected before an injunction can be obtained, be declared a public nuisance, 'damaging the public and this plaintiff's private rights,' and be abated. The special damage alleged is that plaintiff, having erected a building on what he alleges to be the true boundary line of D street, will be, as it was said in the argument, 'put into a hole' by the buildings of defendants projecting beyond it, and that light and air thereto, through the doors and windows of plaintiff's building, will be prevented, and the view therefrom to all parts of D street obstructed, and that 'the light and air and view from all parts of the said D street as the said building [plaintiff's building] is constructed necessarily ensue and benefit the said property materially, and are of great value to the plaintiff, and as is also the right of egress and ingress.'

It is further alleged that, before erecting his building, plaintiff applied to the city en gineer to be shown the original south line of D street according to the original survey, and the engineer ran 'the lines on the ground according to the said original survey and plat,' and that plaintiff erected his building in accordance therewith, 'covering the entire lot.'

It is also alleged that the lots owned by defendants were conveyed by the mayor to the original owners according to the original survey, and 'deeds thereto accepted according to the said original survey and plat, and said lots have since been conveyed to the defendants and their grantors according to the said original survey and plat.' A dedication of the street to the public is averred as hence resulting, and an estoppel against defendants to dispute the survey and plat. The answer of the defendants, in effect, denies the correctness of the survey and plat made by True, and avers that there was an amendment of the latter which exhibited the streets and alleys according to the occupation of the respective claimants of the lots. It is admitted, however, that some of the of the deeds issued were in accordance with the plat, but it is denied that all the deeds were, and averred 'that the same were in accordance with the use and occupation of the lands prior to the survey, and with the said survey and plat, as the same were and had been amended.'

The findings of the trial court sustained these averments, and found further that the True survey as originally made disregarded the lines of occupation of the lots, and 'ran through buildings then in the actual use and occupancy of the claimants of land, and cut off approximately 4 feet from the north end of buildings there standing and in actual use and occupation of bona fide claimants.'

A decree was passed dismissing the suit, which was affirmed by the supreme court. 13 Idaho, 417, 90 Pac. 573.

All of the parties, as we have said, derived their rights and titles under § 2387 of the Revised Statutes, providing for the reservation and sale of town sites on the public lands. That section is as follows:

'Entry of town authorities in trust for occupants. Whenever any portion of the public lands have been or may be settled upon and occupied as a town site, not subject to entry under the agricultural pre-emption laws, it is lawful, in case such town be incorporated, for the corporate authorities thereof, and, if not incorporated, for the judge of the county court for the county in which such town is situated, to enter at the proper land office, and at the minimum price, the land so settled and occupied, in trust, for the several use and benefit of the occupants thereof, according to their respective interests; the execution of which trust, as to the disposal of the lots in such town, and the proceeds of the sales thereof, to be conducted under such regulations as may be prescribed by the legislative authority of the state or territory in which the same may be situated.'

We have not recited, nor do we think that it is necessary to recite, all of the facts found by the lower courts. We may add to those which we have stated that the city of Lewiston was incorporated under the laws of the territory of Washington, it then being within that territory, and was reincorporated by an act of the legislature of Idaho in 1866, it then being within Idaho. The act defined the boundaries of the city. Levi Ankeny was mayor of the city in 1871, and on November 21 of that year he filed his declaratory statement No. 39 in the United States land office at Lewiston, proposing to enter the lands included within the borders of the city as incorporated, in trust for its inhabitants, claiming settlement in 1861. Cash entry was made for the lands June 6, 1874, by Henry W. Stainton, mayor, in trust for the inhabitants. 'The legislature of the territory [we quote from the opinion of the supreme court of the state], by an act approved January 8, 1873 (7 Sess. Laws, p. 16), provided for the survey, platting, and disposal of the land in the city of Lewiston pursuant to the United States statutes in regard to such matters. Said act provides that the mayor trustee shall cause to be made and filed in his office by a competent person a plat of the land within said city, divided into blocks and lots, and 'to make and deliver to the bona fide occupants of such portions of said lands described in said patent from the government of the United States, who may be entitled thereto, good and sufficient deeds of conveyance in fee simple, according to their respective rights.'

'Under the provisions of said laws, one E. B. True was employed to survey and plat the lands in said town, and was commanded to adjust said plat so as to conform to the conditions of the improvements and the use and occupation of such lands by the settler, and the mayor was required to make and deliver to the bona fide occupants of such lands good and sufficient deeds of conveyance in fee simple, according to their respective interests, under the provisions of said law.

'It appears from the evidence in the case that said True made a plat of said town, including block 24, in which block are the lots involved in this case, so as to make the lots about 46 feet long, north and south, when, as a matter of fact, most, if not all, of the lots in that block, were 50 feet long, north and south, as indicated by the buildings and other improvements thereon.'

'The question is fairly presented as to whether said True had any authority whatever to make said plat so as to interfere with and cut off a part of the buildings and improvements of the occupants of such lots. In other words, whether, under the law, a surveyor who is employed to plat such a town site, after its entry by the proper officer, can widen a street, and, in doing so, can cut off a portion of the buildings and improvements of the lot owners bordering on such street.'

The question was answered in the negative, and the judgment of the trial court, which was adverse to plaintiff, was affirmed. In some aspects the answer may be said to have been put upon the statute of the state of January 8, 1873, providing for the survey, platting, and disposal of the land. The court observed that there was no dispute that the evidence established that the defendants claimed and occupied their lots to the extent they had claimed for many years prior and subsequently to the survey, and that it was not shown or claimed that part of the lots was used as a street, nor that the city ever claimed any part of them as a street. And it was said: 'The city surveyor cannot make any portion of said lots a street by simply making a plat and indicating on such plat that said lots were only 45 or 46 feet in length.' The claim by defendants was of 50 feet. The court further said: 'The mayor trustee had no judicial power in this matter; neither had the surveyor. The surveyor and mayor cannot dedicate to the public as a street parts of lots occupied and possessed by individuals.' This, it may be contended, is a mere construction of the statute of the state of Idaho, and nothing more; in other words, a decision that, under the statute, there was no power given to make a survey or plat which did not conform to the lines of occupation. The contention of plaintiff, however, is that 'the laws of Congress authorize an official ascertainment' of the boundaries of the city, and 'that the equitable right under the said laws of Congress vests upon a condition subsequent, which is that the owner of the equity must, within a reasonable time, have his right confirmed by the trustee upon an official survey ascertaining and settling its boundaries and nature, and that the laws of Congress require each town-site occupant to see to it that the official ascertainment is true and correct and satisfactory before accepting confirmation of his equitable rights from the mayor trustee.' It is hence insisted that a construction of the laws of Congress is involved. This contention, we think, is the basis of plaintiff's bill of complaint, and it seems also to have been passed on by the supreme court of the state. The court said: 'The appellant [plaintiff in error here] rests his case here on the making and approval of said plat' (that is, the plat made by True), and the contention was discussed. We think, therefore, the motion to dismiss should be overruled.

But a little more discussion is necessary to pass on its merits. Section 2387 constitutes the grant of title, and it is very explicit as to grantees to the matter granted, and for whose use it is granted. The grant is of lands occupied as a town site, the grantees are the corporate authorities thereof, or the judge of the county court where the town is situated, 'in trust for the several use and benefit of the occupants thereof, according to their respective interests.' And the legislation of Idaho, enacted in pursuance of § 2387, provides, as we have seen, that the mayor shall cause to be made and filed in his office a plat of the land divided into lots and blocks but it is also provided that he is required, as trustee, 'to make and deliver to the bona fide occupants of such portions of said lands described in said patent from the government of the United States, who may be entitled thereto, good and sufficient deeds of conveyance in fee simple, according to their respective rights.' The object of the state legislation, therefore, was to consummate the grant of the government to the occupants of the land, not to alter or diminish it. The grant was through the mayor to the occupants of the lands. The extent of their occupation was the extent of their rights; determined, therefore, the relation of their lots to the streets and alleys; fixed the location of the streets and alleys. Or, as it is epigrammatically expressed by the supreme court of the state, 'it must be kept in mind that Lewiston existed prior to the True survey. The settlers did not acquire their right under the plat nor by virtue of it. The survey and plat were made for them; they were not made for the survey and plat.' But we need not make a universal application of this. It is enough for the present case that the supreme court so construed the power of the mayor and the surveyor under the Idaho statute. It may well be contended, however, that the supreme court expressed a principle that has broader application,—expressed as well the meaning of the act of Congress. In Ashby v. Hall, 119 U. S. 526, 30 L. ed. 469, 7 Sup. Ct. Rep. 308, this court said, speaking by Mr. Justice Field, that 'the power vested in the legislature of the territory [Montana] in the execution of the trust [under § 2387] upon which the entry was made was confined to regulations for the disposal of the lots and the proceeds of the sales. These regulations might extend to provisions for the ascertainment of the nature and extent of the occupancy of different claimants of lots, and the execution and delivery to those found to be occupants in good faith of some official recognition of title, in the nature of a conveyance. But they could not authorize any diminution of the rights of the occupants when the extent of their occupancy was established. The entry was in trust for them, and nothing more was necessary than an official recognition of the extent of their occupancy. Under the authority conferred by the town-site act, the legislature could not change or close the streets, alleys, and blocks of the town by a new survey. Whatever power it may have had over them did not come from that act, but, if it existed at all, from the general grant of legislative power under the organic act of the territory.' See also Stringfellow v. Cain, 99 U. S. 610, 25 L. ed. 421; Cofield v. McClelland, 16 Wall. 331, 21 L. ed. 339; Hussey v. Smith, 99 U. S. 20, 25 L. ed. 314. Many state cases are to the same effect, and may be found in the notes to § 2387 in United States Federal Statutes Annotated, vol. 6, pages 344 et seq.

Further discussion is unnecessary. Plaintiff's other contentions are either disposed of by the facts found by the state courts or do not present Federal questions.

Judgment affirmed.
