The appellant excepts and assigns as error the following portion of his Honor’s charge: “The law says that when you have weighed all of the testimony and evidence in this case in the scales of justice, Thomas’ contentions, evidence and. testimony upon the one side and Hipp’s contentions, evidence and testimony on the other, if the scales shall be tilted downward in favor of Thomas upon the first issue, then it would be your duty to answer the issue either the first line or the second line, as you may find the facts in that degree to indicate.”
We think the exception well taken, since there was no agreement between the parties that the true boundary line between the adjoining *518lands of the plaintiff and the defendant Hipp was one of the three lines designated on the map made by the Court Surveyor as was the ease in Boone v. Collins, 202 N. C., 12, 161 S. E., 543; McCanless v. Ballard, 222 N. C., 701, 24 S. E. (2d), 525. In a processioning proceeding to establish a boundary line, which is in dispute, what constitutes the dividing line is a matter of law, but the true location of the dividing line must be settled by the jury under correct instructions based upon competent evidence. Creer v. Hayes, 216 N. C., 396, 5 S. E. (2d), 169; Greer v. Hayes, 221 N. C., 141, 19 S. E. (2d), 232; Huffman v. Pearson, 222 N. C., 193, 22 S. E. (2d), 440; McCanless v. Ballard, supra.
It will be noted in the statement of facts that the Court Surveyor, in running the two lines shown on the Court map, which are most favorable to the plaintiff, ran both lines from the point designated A, the termination of the first call in plaintiff’s deed, by reversing said call. In running line A to G-., designated by the court as line No. 1, the most favorable line to the plaintiff, the Surveyor made no allowance for magnetic variation. In running line A. to 7, the next most favorable line to the plaintiff, designated by the court as Line 2, the Surveyor made allowance for magnetic variations since 1924, the date of the execution of plaintiff’s deed. .
The plaintiff’s deed, being a junior instrument and calling for a corner in the Hipp land as the beginning corner, and running thence with the line of the Hipp land, is incompetent as evidence to locate the corner or the line referred to and described in the deed previously made to the defendant, L. H. Hipp. Euliss v. McAdams, 108 N. C., 507, 13 S. E., 162; Sasser v. Herring, 14 N. C., 340; Corn v. McCrary, 48 N. C., 496. Also we find that in the case of Dula v. McGhee, 34 N. C., 332, the Court said: “Where a grant calls for the line of an older grant, the rule is, that it must go to it, unless a natural object or a marked tree is called for, and before the calls of the junior grant can be ascertained, those of the elder must be located. This is established by many decisions; Miller v. While, 2 Hay., 160; .... . .......... v. Heritage, 2 Hay., 327; Bradbury v. Hooks, N. C. T. Rep., 1; Tate v. Southard, 1 Haw., 45.”
In the instant case, however, an examination of the description contained in the deed executed in 1912 to the defendant Hipp, will disclose that the description begins in the western edge, of the S. A. L. Railway right of way and continues with couises and distances to stakes, thence to the beginning. A stake is ah imaginary point. The beginning is somewhere in the western edge of the right of way of the S. A. L. Railway Company, but where is unknown. It does not appear from the description in the record that the southern boundary line of the Hipp land can be definitely located which may remit the defendant Hipp to a claim for title by adverse possession. Mann v. Taylor, 49 N. C., 272; Deaver v. *519 Jones, 114 N. C., 649, 19 S. E., 637; Holmes v. Sapphire Valley Co., 121 N. C., 410, 28 S. E., 545; Barker v. Railway, 125 N. C., 596, 34 S. E., 701; Kennedy v. Maness, 138 N. C., 35, 50 S. E., 450; Cathey v. Lumber Co., 151 N. C., 592, 66 S. E., 580; Higdon v. Howell, 167 N. C., 455, 83 S. E., 807. Whether or not any one or more of the corners called for in the Hipp deed are marked by permanent or known monuments, from which corner or corners the line in dispute may be located, under the maxim, id certum est quod cerium reddi potest, is not presented on this record, and therefore the question is not decided. N. C. Self Help Corp. v. Brinkley, 215 N. C., 615, 2 S. E. (2d), 889; Duckett v. Lyda, ante, 356, 26 S. E. (2d), 918; Peel v. Calais, ante, 368, 26 S. E. (2d), 916.
A deed which is inoperative because the land intended to be conveyed is incapable of identification, from the description therein, is inoperative as color of title, Katz v. Daughtrey, 198 N. C., 393, 151 S. E., 879; hence, if the defendant Hipp is remitted to a claim for title by adverse possession to establish his line which is in dispute, the adverse possession must have been for twenty years prior to the institution of this proceeding. The defendant’s southern line wherever established, whether from the description in his deed or by adverse possession for the required statutory period, will constitute the northern line of plaintiff’s land and the true dividing line between the adjoining lands of the plaintiff and the defendant. Hipp. However, the burden being on the plaintiff'to establish the true dividing line between the adjoining land of the plaintiff and the defendant Hipp, and it not appearing from this record that the southern boundary line of the Hipp land can be definitely located from his deed, the plaintiff may make out a prima facie case for the consideration of the jury upon competent evidence as to the location of the true boundary line as called for in his deed by a reverse survey of the course and distance of the first call in said deed, which calls for a known and established corner. Jarvis v. Swain, 173 N. C., 9, 91 S. E., 358; Land Co. v. Lang, 146 N. C., 311, 59 S. E., 703; Dobson v. Finley, 53 N. C., 498. In determining the location of this line, proper magnetic variations since 1924 should be allowed. But, as stated above, the location of the boundary line as called for in the junior deed will not be controlling if the true location of the boundary line can be ascertained from the Hipp deed or by the adverse possession of the defendant Hipp of the land intended to be conveyed to him in the deed executed in 1912. If, however, the true boundary line between the adjoining lands of the plaintiff and the defendant Hipp cannot be established from the description in the Hipp deed or by the adverse possession of the defendant Hipp, south of the course called for in the first call of plaintiff’s deed, the *520course and distance as given in plaintiff’s deed may prevail. Lumber Co. v. Bernhardt, 162 N. C., 460, 18 S. E., 485.
The party asserting title by adverse possession must carry the burden on that issue. Power Co. v. Taylor, 194 N. C., 231, 139 S. E., 381.
For the reasons stated, we think there should be a new trial; however, we suggest a recast of the pleadings so as to present the question of adverse possession to the jury should the submission of such an issue become necessary. •
We deem it unnecessary to discuss the other assignments of error, since they may not arise on another trial.
New trial.
