This action was commenced by the plaintiff against the city of Los Angeles to quiet title to a certain lot of land at the northeast corner of Spring and Fourth streets in the said city. The city filed a cross-complaint alleging that the appellant, Roaz Duncan, and other parties, all of whom were subsequently brought in and made parties to the action, owned lots along and fronting on Fourth street, on both sides thereof, between Spring and Main streets, and that all these lotowners, including the plaintiff, had “so encroached upon Fourth street, both upon the north and upon the south, that the width of said Fourth street, as it now exists upon the ground between the fences and other improvements of said parties, is considerable less than sixty feet.” The cross-complaint also sets forth that in 1849 a survey and map of said city was made, known as Ord’s survey, which was adopted as the official map of said city, and which shows Fourth street to have a uniform width of sixty feet. The principal relief prayed for in the cross-complaint is that the lines of Fourth' street be determined, and that the claims adverse to the use of Fourth street as a public street of said city be forever quieted. The appellant demurred to this cross-complaint for insufficiency of facts to constitute a cause of action, and for uncertainty because the north and south boundaries of Fourth street were not set out and it could not be ascertained therefrom to what extent the improvements of the several parties, including appellant, encroached upon said street. In overruling this demurrer the court erred. The complaint was uncertain in the particulars specified in the demurrer. Whether the suit be treated as an action to quiet title or to establish the boundaries of Fourth street, the appellant was entitled. to be informed by the cross-complaint specifically as to *386what portion of the premises occupied by him were claimed to be an encroachment and within the boundaries of Fourth street.

We are also of opinion that the evidence is insufficient to justify the decision of the court. So far as the appellants’ rights were concerned, the question of fact to be decided was as to tire exact location of the south boundary of Fourth street, at the place where appellants’ property was located, according to Ord’s survey, which is conceded to be the original and official survey of the city of Los Angeles. Appellants introduced evidence tending to show that those under whom they claim title acquired the same by deed from the city of Los Angeles November 21, 1855, and that appellants’ predecessors in interest erected a picket fence along Fourth street, on the line now occupied by the northerly line of appellants’ building on the southeast corner of Spring and Fourth streets; that said fence was moved in the year 1888, when said building was erected; that said Fourth street was paved and the sidewalk built to the line occupied by said building, and the owners of said property paid their proportion of said assessment for said paving up to said line; that up to 1897 all the improvements on the south side of Fourth street, between Spring and Main, were on a line occupied by defendants’ building and had occupied that line for at least twenty-five years prior thereto. This was the best evidence introduced and the only competent evidence offered to show the location of the south line of Fourth street.

The testimony of the engineers was incompetent to establish the location of Fourth street, and the objection to such testitimony should have been sustained, and the same may properly be said of the maps, with the exception of the Ord map; this map, and the contract in pursuance of which it and the Ord survey were made, was proper evidence in the ease, but the map could not locate itself on the ground. It appeared in evidence that all the monuments of the Ord survey were lost, and no attempt was made to establish their location, 'either by reputation, the declarations of deceased persons, or by the testimony of witnesses having knowledge of such location, but it soems that in the absence of any such evidence the engineers have. attempted to locate the streets by selecting the most uniform street in the oldest part of the city, and, assuming that one boundary of that *387street is on the Ord survey,they propose to locate the other streets of the city by first measuring the distance required by the Ord map and then adding to or subtracting from such distance as may be required to leave all the streets of a uniform width of sixty feet and require the removal of as few buildings as may be. In making their measurements on the ground they have disregarded the Ord map. They make the block in which appellants’ lot is situated five hundred and ninety-nine and seventy-six one-hundredths feet long, and the block immediately across Fourth street from and north of said lot they find to be six hundred and five and seven one-hundredths feet long, whereas the Ord map gives the blocks a uniform length of six hundred feet. They might have come nearer the map if they had given the blocks on each side of Fourth street a more nearly uniform length by placing Fourth street two or three feet further north. The work and testimony of the- engineers is only a guess at the location of Fourth street as originally established by the Ord survey. It may be proper, in the absence of any better evidence, to regard the line of ancient and continuous improvements as evidencing the line of Sixth street as it was run by the Ord survey, but no use of this line can be made to establish any other line in the city for two reasons: 1. The engineers have demonstrated by their measurements, and their testimony is an admission, that the Ord survey must have been very inaccurate; 3. The inaccuracy of the early surveys in California, as well as in other states, is a matter of such common knowledge that the courts are warranted in taking judicial cognizance of the existence of such inaccuracy, as they frequently have done. It needs no argument to show the impossibility of locating an unknown line of an inaccurate survey by running from a known line of the same survey. In the absence of better evidence, the court might have been warranted in finding for appellants on the evidence as to the south boundary of Fourth street as it had been indicated on the ground by the line of fence and other improvements for twenty-five years. (Diehl v. Zanger, 39 Mich. 601; Orena v. Santa Barbara, 91 Cal. 621.) There was no competent evidence in the testimony or maps of the engineers to show the location of the southern boundary of Fourth street, and, therefore, the judgment of the court has nothing to support it. We *388think the conclusions reached herein find support in the following cases: Payne v. English, 79 Cal. 540; Los Angeles v. Cohn, 101 Cal. 374; Bullard v. Kempf, 119 Cal. 9; Orena v. Santa Barbara, supra; Ralston v. Miller, 3 Band. 44; 15 Am. Dec. 704.

For these reasons we advise that the judgment and order appealed from be reversed.

Cooper, C., and Chipman, C., concurred.

For the reasons given in the foregoing opinion the judgment and order appealed from are reversed.
