¶1The purpose of this suit is to have the boundary line between plaintiffs’ estate and defendant’s settled and determined.
¶2There is no question of title.
¶3Originally, these estates formed part of a large tract which has since been subdivided. It now belongs to different owners.
¶4The contention on the part of plaintiffs is that the lines between the two estates have never been determined and fixed, or, if ever fixed, that the lines have become obliterated.
¶5Plaintiffs claim that they and their authors had been in possession of the land, the boundary of which they seek to have fixed, since many years.
¶6In accordance with the application of plaintiffs, a surveyor was appointed to survey the land.
¶7In an exception, which was thejfirst appearance made by the defendant, she averred that plaintiffs had no cause of action, or, if they ever had such a cause, it was barred by the prescription of 10 and 30 years, dur-1 ing which time, she had, as she averred, open and uninterrupted possession.
¶8She also averred that the boundary lines between the two estates were well defined and had long since been established.
¶9The exception, was referred to the merits, and the defendant thereafter filed a general defense.
¶10The surveyor was appointed in accordance with the order of court, and, in his return, stated that, after consulting all the data at hand and after running different lines, he had arrived at the conclusion that the post known as the “Bradford Post” was a correct point of departure; that this post is at or near the corner of townships 10 and 11, ranges 3 and 4 E.
¶11That he had found another surveyor’s mark at the northeast corner of the Francois Broussard concession; that, by following distances and the bearings of old surveys, and closely consulting and following a map in evidence in suit 1779, he had found that part of the tract known as the Eugene Broussard tract was within the inclosure of the defendant, and that this tract measured 1198o/100 acres.
¶12On his own motion, he was allowed to withdraw this return made of his survey.
¶13This survey is one of the incidents of the suit to which we will have no occasion to return.
¶14Some time after, the surveyor made another survey, of which he made a map, which was introduced in evidence, and he was examined as a witness at some length on the application made by plaintiffs to homologate and approve this second survey.
¶15The defendant objected to the homologation and approval, and filed grounds upon which the objection was urged.
¶16These grounds in substance were:
¶17That the field notes were not produced and that the lines were not located.
¶18Defendant also objected on the ground *712that the surveyor had not given the quantity of land in each tract.
¶19, On his direct examination, in support of his survey, he succeeded in explaining clearly enough the methods followed in making the survey, which had every appearance of being correct.
¶20The surveyor had made three surveys of the land; one in 1908, another in 1909, and a supplemental survey, supplementing that which needed to be supplemented in the last survey.
¶21This offered inviting field for cross-examination.
¶22This witness was placed somewhat at disadvantage under the cross-examination. He did not succeed in clearly explaining why he selected the point of departure as he did.
¶23None the less, the survey was accepted by the district judge, who was not thoroughly convinced, as he stated in his written opinion, that he should accept it, as it did not seem to be conclusive on a certain point.
¶24The judge further stated in his written reasons for judgment that it was not advisable to set aside this survey and order another for the reason that it was not probable that another survey would be more satisfactory in view of the uncertainty about the point of departure and because, as we infer, of the conflict in the testimony of the witnesses.
¶25All of the lands involved are within the Eranqois Broussard concession, an ancient and well-known concession.
¶26Two of the surveyors adopted the maps and field notes of the United States surveyors to some extent at least.
¶27We are informed that near the point of departure there is a witness tree and other surveyors’ monuments.
¶28The surveyor appointed by the court testified that his line was correct according to the field notes.
¶29He also studied carefully and followed closely* map A in evidence handed to him at the time by counsel for defendant.
¶30When the surveyor’s map was offered, counsel for defendant objected on the ground that the survey did not agree with the partition which was re-established by this court in the case of Broussard v. Guidry, 114 La. 913, 38 South. 616.
¶31He also testified that the point of departure was 2S chains and some links from a coulee known as the Coulee Isle aux Nois.
¶32This is the distance according to this witness from the township line at that point to that coulee.
¶33Campbell, the United States deputy surveyor, located the township line at that point at 12 chains and some links from the coulee, making a difference of 13 chains between the two.
¶34This witness testified that from all the data he had gathered he felt confident that there was no material difference between his survey and the previous surveys made. 1-Ie felt’ confident that it corresponded with the field notes; that the township line at that corner was the proper starting point.
¶35Other testimony on the same subject reduces the difference in measurement between the township line to the coulee.
¶36Of this later.
¶37Judgment was rendered, establishing the boundary line between plaintiffs and defendant ; overruling the plea of estoppel and the plea of prescription of 10 years, but maintaining the prescription of 30 years to that part of the property claimed by defendant lying north of the doube ditch, described in the testimony in the above cause, and between the rear concession line and the ditch or fence running north 13 degrees, 30 minutes, west, between lines in possession of plaintiffs and defendant, and disallowing the purported act of exchange.
¶38There was an act of exchange between Eugene Broussard and Treaville Guidry.
¶39*714Guidry transferred a small tract of land to Broussard and Broussard transferred his land in exchange. This was in 1870.
¶40The agreement of exchange, to ■ which we will have ’ occasion to refer later, was very informally drawn.
¶41Plaintiffs’ contention is, as to this exchange, that defendant had no title and no possession upon which to base the plea of 10 years’ prescription; and, as it is, defendant has not shown that 30 years had elapsed.
¶42To these grounds, we will have to refer again later.
¶43In this court, the appellee asks for an amendment of the judgment by recognizing the defendant as owner of the land acquired by her in exchange with Eugene Broussard under whom, by mesne conveyance, he owns.
¶44The further contention as relates to this application to amend the judgment is that the agreement of exchange, annexed to and forming part of defendant’s answer, should be recognized as an agreement translative of property and sufficient to support the 10 years’ prescription, and, thereby, enable the defendant to recover all the lands transferred to her ancestor in title under the agreement of exchange.
¶45The appellee further averred in substance that the court’s recognition of the survey of Ernest Montagne is'not correct, for the reason that he ran the line from the northwest corner of the Erangois Broussard concession, a point over 28 chains north of the Coulee Isle' aux- Nois, while original surveys and others subsequent show that the point of departure before referred to is not over 14 chains north of the coulee.
¶46■The defendant acquired about one half of Bugebe Guidry’s land in the Erangois Broussard concession. The other half of the Eugebe Guidry tract was acquired by Cordelia Guidry. Both were daughters of Eugebe Guidry, a former owner.
¶47There can be no question, as contended by plaintiffs, possession upon which prescription acquirendi causa is founded must be continuous and uninterrupted; it must be public and under the title of the owner. Civ. Code, art. 3800.
¶48The defendant had such a possession (to the extent that our decree recognizes possession in defendant) to the land to which we have just referred.
¶49The possession of defendant’s author and her own date back over 30 years prior to the filing of the suit; that is, possession of the land of which she is recognized as being the owner.
¶50She paid the taxes from the date of the exchange and exercised all the rights of ownership.
¶51The extent of the possession gives rise to the issues.
¶52In order to arrive at that extent, it was necessary to establish the boundary lines.
¶53This suit was instituted and after issue joined, a surveyor was appointed by the court with consent of parties.
¶54Surveyor Montagne was appointed.
¶55With regard to the survey referred to.as “the Montagne Survey,” made under the order of the district court, that court, although it considered that the survey was not all it should be, said, in his written reasons for judgment, that “it may be that no better can he made.”
¶56None the less, the court approved the survey.
¶57Appellants ask that the ease be not remanded, and appellee does not argue that there is necessity of remanding the case..
¶58It is reasonable to infer that there were established points of departure for making surveys in the old Erangois Broussard concession.
¶59The surveyor who made the last survey, before referred to, said that he sought to follow ancient lines, and that he had succeeded in finding them; that he began his *716survey from the point in the field established by the United States surveyors; that he found a post referred to by Bradford in his field notes.
¶60There was nearby a witness tree; that he measured the distance from the post to the Coulee Isle aux Nois.
¶61• Prom that point he ran back a stated distance to the intersection of the range line and on to the end of the survey.
¶62He stated that he based his survey on map A, handed to him by counsel fo.r defendant prior to the survey.
¶63With the testimony of this witness, his plat was offered in evidence, to which the counsel for defendant objected on the ground, among others, that it did not agree with the map of the partition, re-establishing one of the lines by this court.
¶64The objection was properly overruled and the map was admitted. There is not such a marked disagreement between this map and the other evidence.
¶65This surveyor testified that he initiated his survey from the township corner at a post placed by the government surveyor, Geo. K. Bradford, and that there was another with which he identified at the northwest corner of section 40, township 10 S., range 3 East, a common township corner; that he found a piece of a plow designated on the field notes of Bradford and Campbell, United States surveyors under the post; and that he also found a witness tree at this corner; that certain distances measured convinced him that the post is correct.
¶66The witness’ measurement of distance to the Coulee Isle aux Nois has given rise to serious controversy.
¶67He says that he measured 12 chains and 32 links to the township line .and 16 chains and 35 links from the township line to the coulee, making 28 chains and 67 links, while' the Campbell survey shows 12 chains and 32 links from the corner to the township line, and 2 chains and 75 links to the coulee instead of 16 chains and 35 links.
¶68As relates to survey, the controversy is limited to the distance between the township line at the point in question and the coulee before mentioned.
¶69The Campbell survey is an old survey, and, while there is some reference to it by Bradford, he does not give the figures of measurement between township and coulee.
¶70The corners adopted were located by different surveyors; among them, Edwards, an old surveyor of experience, Port, and others.
¶71The field notes do not entirely agree; there are discrepancies. Old surveys are not always correct. By common consent the new points of departure have been adopted.
¶72The original government surveys may not be at the place since adopted by other surveyors. There seems to be well-established landmarks adopted since. Some of them received some recognition in the decision cited supra.
¶73We would not be justified in going back to the original survey to follow it. Were we to do so, it would change a number of lines. They would have to be located further south about 13 chains. This we will not do save on the best of proof.
¶74The evidence is not before us to justify that change.
¶75Our learned brother of the district court states in his written reasons that there are discrepancies in the original surveys in that part of the country which can never be satisfactorily reconciled. “My fear that another survey would only add another doubt and do little good causes me to adopt the one already made.”-
¶76There is another significant fact; The defendant claims other land, although she has over her complement of land.
¶77The surveyor returns that she has in her possession in excess of her allotment in a partition, especially referred to, 93t9/100 *718acres, while plaintiffs are short in the measurement of their land 8437/100 acres.
¶78This, to say the least, is corroborative of the lines established.
¶79Defendant and her authors having had possession, we maintain the prescription of 30 years.
¶80This brings us to a consideration of the plea of 10 years’ prescription, interposed by defendant.
¶81She claims a portion of the land by virtue of and under a plat and asserted agreement of exchange, dated in 1870. This plat was not recorded; it was found in the possession of the defendant 25 years after, its purported date. The proeés verbal of the surveyor was used in order to have it appear that a sale was made. The indorsement on this plat was something in the nature of a sale. It was not regularly signed, if signed, at least as to one of the parties.
¶82It was offered in evidence as an ancient document, admissible without proof.
¶83It was admitted in the district court, in connection with the prescription of 30 years.
¶84There is no law in this state fixing the period of time to establish an ancient document.
¶85As relates to the purported date, it is not conclusive. Any one can write a date as of yesterday.
¶86There is no evidence showing that the document existed from the day of the purported date.
¶87The rule is that all documents evidencing the conveyance of realty be recorded.
¶88In the absence of a recorded deed, in order that an instrument may be admitted in evidence, it must clearly appear that it is what it purports to be.
¶89Moreover, the signature of one of the parties was not affixed to the indorsement on the surveyor’s map.
¶90It served the only purpose for which it could serve. It does not prove title, inasmuch as it is not evidence of the consent of ,the parties, one of whom it does not appear signed.
¶91It was not admissible as a title, even among the descendants of those who signed.
¶92In that light (that is, to prove title) it is a nullity.
¶93With regard to the objection, noted above, to wit, that the map of the surveyor, Montague, should not be admitted in evidence, because it differed from the sketch and from the conclusion of the court in the decided case of Broussard v. Guidry, 114 La. 918, 38 South. 616.
¶94The evidence was properly admitted, for the Montague survey agrees with the sketch.
¶95In following the different lines of the sketch it will be seen that the court heretofore adopted the northern boundary of the land, as did Surveyor Montagne.
¶96As to these strips of land exchanged as before mentioned, the one intended for Mrs. Guidry was not taken possession of at the date of the purported exchange.
¶97She had no title, and has not acquired a prescriptive title under 10 years’ prescription. Possession and title acquired in good faith are essential to sustain the plea of 10 years’ prescription to acquire immovables by that prescription.
¶98After issue joined in the district court Mrs. Guidry died, and her heirs were made parties. For brevity, we used the name of the original defendant.
¶99For reasons assigned, the judgment is affirmed at appellants’ costs.
