Appeal from the order granting a new trial. Plaintiffs, who- at the date of the commencement of this action were minors, averred their ownership and possession of a piece of land situated at the corner of Beach and Hyde streets, in the city and county of San Francisco. They further averred that defendant asserted title to the land; that this title was based upon a deed obtained by defendant’s grantor from the city and county of San Francisco by fraud. After the United States had granted the land to the city and county of San Francisco, upon trust to convey to those in bona fide possession at the date of the passage of said act (July 1, 1870), defendant’s grantor falsely and fraudulently represented himself to hold such possession of said land, and thereby procured a deed to the same from the city. At the date of the passage of the act, defendant’s grantor was not, but plaintiffs’ grantors were, in such actual possession, all of which was well known to the defendant at the time he took his deed. The prayer was for a decree declaring defendant to hold his title in trust for plaintiffs and compelling him to convey the same to them.
For answer the defendant made denial, pleaded the *50statute of limitations, and by cross-complaint setup his title and asked a decree establishing it as good and valid. Though the action was in equity, the court impaneled a jury, whose verdict, being advisory merely, it was in nowise bound to accept. At the conclusion of the evidence the jury was instructed to render a verdict for defendant, which it did, and judgment was entered in accordance therewith.
Thereafter plaintiffs moved for and obtained a new trial, from the order granting which this appeal is taken. The grounds urged for the new trial were newly discovered evidence, insufficiency of the evidence to justify the verdict, and errors of law occurring at the trial. The court in granting the motion based its order upon the single ground that it had erred to the prejudice ■of plaintiffs by admitting in evidence a portion of a map—which ruling will hereafter come under review.
This order of the court relieves from consideration the question of the sufficiency or insufficiency of the evidence. (Kauffman v. Maier, 94 Cal. 277.) While it is true that in actions at law, where a trial by jury is a matter of right to either party, it is error for the court to instruct the jury to render its verdict for one or the other when the evidence is conflicting—the rule does not obtain where in equity a jury is impaneled merely as a body advisory to the court to assist it in determining disputed facts. In such cases the court may even? under conflicting evidence, reject the verdicts general or special of the jury, and enter a decree in accordance with its own determination, or, what is an equivalent, it may direct a particular verdict upon the facts as being in accord with its own conclusions. There was no error therefore in the court’s instruction, even if it be conceded that the evidence was conflicting.
But in truth the evidence was not conflicting; or, even if by a most liberal concession a conflict be acknowledged, it was upon matters which by reason of other considerations could not have advantaged the plaintiffs if the disputed points had been determined *51in their favor. To make this apparent a review of the facts here becomes necessary.
In 1850 the President of the United States by proclamation reserved for public purposes certain lands upon the peninsula of San Francisco at Point Jose or Point San Jose, now commonly designated Black Point. By later proclamation in 1851 the boundaries of this reservation were reduced and made to embrace the fol. lowing tract: “The promontory of Point Jose within boundaries of not less than eight hundred yards from its northern extremity.” By all the evidence in the case uncontradicted it appears that the lot in question was within the boundaries both of the original and of the reduced reservation.
By act of Congress of 1870 (16 U. S. Stats, at Large, c. 197, sec. 16), in which the United States relinquished certain of these reserved lands to the city and county of San Francisco, one of the trusts declared was “to grant and convey the remainder of said land to the parties severally, who are, at the date of the passage of this act, in the actual bona fide possession thereof, by themselves or their tenants, and in such parcels as the same are so held ■ and possessed by them; or who, if they have not such possession, were deprived thereof by the United States military authorities when they went into the occupancy of said military reservation, or were deprived thereof by intruders or trespassers, against whom possession may be recovered by legal process.”
Defendant’s predecessor in interest made proof of his right to a deed to the land in question under this act, and through this source title vested in defendant by deed of the city December 24, 1870.
Plaintiffs introduced a deed of the land from the commissioners of the funded debt to J. W. Bowman, acknowledged in November, 1852; a deed of an undivided one-half thereof from Bowman to S. Hopkins, acknowledged in January, 1853; a deed from Bowman to plaintiffs of his remaining interest, acknowledged in July, *521881, and a deed from Hopkins to plaintiffs of his interest, acknowledged in April, 1880.
Their title from this source depends for its validity upon the soundness of the claim which they urge, that the land originally belonged to the city of San Francisco. This claim, however, is untenable. Upon the conquest of California title to the lands of the pueblo which had not passed into private ownership vested in the United States. (Grisar v. McDowell, 6 Wall. 364; Trenouth v. San Francisco, 100 U. S. 253; United etc. Assn. v. Knight, 85 Cal. 470; Thompson v. Doaksum, 68 Cal. 596; People v. Holladay, 68 Cal. 443.) It is not claimed that these lands were held in private ownership prior to the commissioners’ deed. And, as it has been decided that the reservation of the presidio was a valid executive act which excluded these lands from acquisition by private individuals (Grisar v. McDowell, supra), it follows, necessarily, that the commissioners’ deed was ineffectual and worthless as a conveyance of title.
Plaintiffs next sought to establish a title by adverse possession; but, as they were unable to prove payment of taxes for the requisite number of years, their claim failed so completely and admittedly that it is not even argued in their briefs.
Plaintiffs’ final effort was directed to showing that defendant’s predecessor was not in the bona fide possession of the land at the date of the act of relinquishment, and that defendant’s deed was, consequently, procured by fraud. But neither of the plaintiffs who are minors was born at the date of the passage of this act. They themselves cannot claim, therefore, as beneficiaries under the a'ct. They must rely, as was admitted, upon the strength of their grantors’ rights. In this regard, then, they occupy the same and no better position than would these grantors. As to them, the fraud, if fraud there be, was committed in 1870. They were chargeable with knowledge of it, since not only were the proceedings public, but they culminated in a recorded *53deed to the property which they claimed. This cause of action then was long barred as to the grantors of plaintiffs, and, consequently, to plaintiffs themselves. (Love v. Watkins, 40 Cal. 561; 6 Am. Rep. 624; Croghan v. Spence, 71 Cal. 125: Hecht v. Slaney, 72 Cal. 366; Ohm v. San Francisco, 92 Cal. 445.)
Moreover, the deed to defendant, like a patent, is prima facie evidence that the officers performed their duty in issuing it, and so, that it was issued to the rightful claimants. These presumptions can be attacked only by him who connects himself with the title, and not by a stranger, or one in hostility to it. (Low v. Lewis, 46 Cal. 549; McCreery v. Sawyer, 52 Cal. 257; Latham v. Los Angeles, 87 Cal. 514; Payne v. Treadwell, 16 Cal. 220; Doll v. Meador, 16 Cal. 295; Churchill v. Anderson, 56 Cal. 55; O’Connor v. Frasher, 56 Cal. 499; LeRoy v. Cunningham, 44 Cal. 599; Naglee v. Palmer, 50 Cal. 641; Palmer v. Galvin, 72 Cal. 183; Chapman v. Quinn, 56 Cal. 266; Peabody v. Prince, 78 Cal. 511.)
It was incumbent on plaintiffs, therefore, first to prove that they or their grantors were in the actual bona fide possession at the date when the act went into operation, and this, as the court says and the evidence shows, they signally failed to do. The utmost which their evidence can he claimed to establish is that no one held such possession; but such a showing leaves plaintiffs strangers to the title, and against them on this ground the deed of the city to defendant becomes conclusive, since they cannot be permitted to attack it.
In proof that the land was within the limits of the military reservation there was admitted in evidence over plaintiffs’ objection a portion of a map of the reservation showing the location of the land with relation to the boundary of the government tract. The judge granted the motion for a new trial upon the sole ground that he believed he had committed error in admitting this evidence, and, as it was evidence which greatly influenced him in his determination that the *54land was a part of the Presidio reservation, lie deemed the ruling to be prejudicial to the interests of plaintiffs.
We think the learned judge, in his conscientious efforts to avoid injustice, here, and not upon the trial, fell into error.
The drawing, which was a portion of a map, was offered with the following certificate:
“I,- Charles S. Stewart, colonel of the United States corps of engineers, do hereby certify that I am the legal custodian of a map of the Point San Jose U. S. military reservation, as located within boundaries of not less than pight hundred yards from said point, and that said map was prepared by and is part of the records of the United States War Department, and that this map is a true and correct copy of so much of the original map in my custody as embraces the tract of land located in the city and county of San Francisco, within the former boundaries of said reservation, and bounded northerly by high water mark of the bay of San Francisco, easterly by the former eastern boundary of said reservation as originally located, southerly by North Point street, and westerly by Larkin street.
“In witness whereof, I have hereunto set my hand and private seal (having no official seal) this sixteenth day of April, 1883.
“[seal] C. Seaeorth Stewart,
“Col. of Engineers, U. S. A.”
This certification is in strict accord with the provisions of sections 1918, subdivision 9, and 1923 of the Code of Civil Procedure.
The objections made by plaintiffs to the introduction were two: 1. That the whole map should be introduced, and not a part; and 2. That there is no law making Colonel Stewart a certifying officer of a copy of the map.
As to the first of these objections it is sufficient to say that section 1923 of the Code of Civil Procedure contemplates and provides for the introduction in evidence of a part of a map or document. The object of the *55evidence was to establish that the land in question was within the boundaries which the United States government had set to the reservation, and that portion of the map was offered which showed the land and the inclosing boundary. The whole map would have showed no more, or, if it would, it became the duty of plaintiffs’ attorney, who had himself, under direction of the court, inspected the original instrument, to point out the precise particular in which the offered portion worked an injury by its incompleteness, or failed fully to express the truth of the matter sought to be proved. He did not do this. If the whole map would have shed no more light upon the question, the offered portion was material and admissible, and the remainder immaterial and unnecessary.
The second ground of objection, which was that “there is no law making Colonel Stewart a certifying officer of a copy of the map,” is no better founded than was the first. The objection is tantamount to an admission that the map is a record of the war department, and that Colonel Stewart is the legal custodian thereof, as he well might be under the customs, rules, or orders of the department. The certificate also recites these facts. Assuming them as true, the law authorizing him to make the certificate is found in section 1918, subdivision 9, of the Code of Civil Procedure. Moreover, the official character of the officer as the legal custodian of the document, and therefore authorized to certify a copy of it, is proved prima facie by the certificate itself. (Mott v. Smith, 16 Cal. 533, 552.) And finally an error in admitting the map could not have been prejudicial to plaintiffs, because: 1. There was sufficient independent and uncontradicted evidence to show the location of the land; 2. By presumption, the deed from the city to defendant, which deed plaintiffs introduced in evidence as part of their case, showed the land to be within the reservation (Collins v. Bartlett, 44 Cal. 383); 3. Plaintiffs pleaded that the land was granted by the United States to the city and county of San *56Francisco in trust, and failed to connect themselves with this government title.
As to the alleged newly discovered evidence, it was either cumulative upon the proposition that no one was in the actual bona fide possession of the land at the time the act of Congress became operative, or it sought to show that though the land was taken by the United States authorities, and was within the boundaries which they laid out, still these boundaries were incorrect. Even if this latter evidence were admissible, no diligence is shown and no reason why it was not procured upon the trial. At the same time it clearly appears by counter-affidavits that plaintiffs’ guardian, by reason of former litigation between the parties over the same land, must have been fully advised as to its materiality and bearing upon the present case.
The order is reversed and the cause remanded, with directions to the trial court to deny the motion for a new trial.
