The land in controversy is included within the lines indicated on the map by the letters and figures 8, I, 1), C, B to 8, and the first question íaised by the testimony was whether the limits of the John Gray Blount patent extended north to V and then ran south 82 east so as to include the locus in quo, or no further north than A, so that the next line would run south of it to B. The call of the patent which gave rise to the dispute was, “ Then with the same (English’s ditch just previously mentioned as the terminus of the line running west 220 poles) and the road northwardly seven hundred and fifty (7/50) poles to a point 160 poles from the lake along the road.” If the point A had been shown by undisputed testimony or had been admitted to have been 160 poles from the margin of the lake and along the road mentioned when the survey was made under which the grant was issued, such positive proof would have controlled course and distance and established the location of the comer at A, though less than 7/50 *81poles from the last station. Strickland v. Draughan, 88 N. C., 315. But as the testimony was conflicting it was the province of the jury to determine whether the corner was satisfactorily shown to have been originally located at A, and if, in their opinion, the actual site of that corner was left in doubt by the evidence, it was their duty to be guided by what would in that event be the more certain description- — -the course and distance. This controverted question of fact was therefore properly submitted to the jury with appropiate instruction for their guidance. Marsh v. Richardson, 106 N. C., 539; Dobson v. Whisenhant, 101 N. C., 645; Jones v. Bunker, 83 N. C., 824; Redmond v. Stepp, 100 N. C., 212; Spruill v. Davenport, 1 Jones, 203.
If the Blount patent issued in 1799 covered the. land in dispute an older outstanding title was shown than the grant to Watson in 1817, and the plaintiff could not. recover. But in case the jury fixed the location of the disputed corner of the older patent at A it became necessary for the defendant to fall back on his second ground of defence — that ho and those under whom he claimed had acquired title by possession under the deed of Smallwood to Thomas Gibbs in 1849, and the devise of Thomas Gibbs to the defendant in 1854, as color. The boundary of the grant to William Watson is admitted to be correctly indicated on the map by the lines 1, 2, 8, 4, 5, 6, 7, 8, I, and to include the locus in <pio, and if the Blount patent was bounded on the north by the line B it did not -cover the disputed territory. The calls of the Smallwood deed, which gave rise t-o the controversy as to the location of its boundaries, were as follows: '• Then (viz., from the south-west corner of the Reuben Benson tract where he formerly lived) with Benson’s line to his south-east corner of his said tract, now •John Benson’s; then eastwardly with the line of the John G. Blount 10,240-acre grant, to a stake, 150 poles from Bam *82Weston's (deceased) house, where he formerly lived, on the lake; then south to the West Bluff Bay; then down said bay to the sound.” It was admitted that Reuben Benson’s south-west corner was at a ¡joint indicated on the map by the letter T and that the next calls were properly run to 7 and 8, and the defendant contended that the “stake loO poles east of Sam Weston’s house” was located at l,and that the boundary extended then to S so as to include the locus in quo (by running to the other points called for) within the bounds of the tímallwood deed — while the plaintiff insisted and asked the Court to instruct the jury, that there was no testimony tending to show where the stake called for was located, and that consequently the true line was from 8 to B instead of to 1, thus locating the northern boundary of the Smallwood deed south of the disputed land at 8 to B instead of along the line 1 to tí. The surveyor Wahab had testified, without objection, that while he did not know where the Samuel Weston house was built he know where Bluff Bay was, and “ the other points called for in the Smalhuood deed south of the point 8, and from such knowledge that the remaining lines of the i.Smallwood deed would close up and embrace the locus in quo.” It does not appear that the plaintiff’s counsel examined the surveyor so as to test the grounds of his opinion before the jury. Without further inquiry as to the manner of acquiring a knowledge of the location of the remaining corners the jury might fairly have drawn! the inference that the surveyor knew, from sources satisfactory to him, vdiere the ¡joint of intersection with Bluff Bay "was, and had demonstrated the fact, by surveying and ¡¡lotting, that only a line run south-wardly from 1 to S would fill the description of both calls first “ vdth the line of the .John (4. Blount 10,240-acre survey,” and then southwardly to the known corner on the bay. Upon this point the Court «'fused the request of the *83plaintiff' to instruct the .jury that 'there was no testimony to show the location of the stake, and instructed them, among other things, as follows :
“Defendant contends that the true location of the deed calling for the Benson line to his south-east corner of his said tract, now .John Benson’s, runs from T to 7; then to 8 ; then to 1; then along the line of the Weston Long patent to the point 8, and then to close in the lines of the deed, in which case it would include the land in controversy.
“Now, if the jury are satisfied, from the evidence, that the Benson line called-for in the ¡Smallwood deed runs to 7, to 8, then north to 1, and then along the Weston Long patent to ¡S; if the point tí was the south-east corner of the Benson land called for in the Smallwood deed and the line approaching it and called for in such deed was along the Weston Long patent from 1 back to 8, to 7 and then to T, being a known and visible line, then the possession of defendant in such deed and in the Watson grant for the seven consecutive years would mature their title to such boundary.
“And this would be true were the said possession, was the south land, marked in plat, ‘Land in dispute.’”
The Court here recited all the evidence, and stated the position of parties on this point and referred to call in deed for running easterly with the Blount line as evidence and circumstances on location, telling the jury the occupation of defendant of land in dispute since 1867 was not sufficient to ripen title, because of the suit of plaintiff'in 1876, and that the time from May 20, 1861, to January 1, 1870, would not be counted.
The Judge evidently submitted the question of location to the jury in view of the surveyor’s testimony taken in connection with the call in the deed for running with the line of the Blount survey, and we think, for the reasons *84given, that there was no error in so doing. In addition to the evidence of AVahab it appears also that another surveyor, George W. Swindell, testified without objection that Marshall Swindell had pointed out the place indicated by S on the map as a corner of the Benson land, and this tended to strengthen the other testimony offered to locate the line 1 to S. But when it is admitted that the Watson grant embraced within its limits the land in dispute, if the Blount patent did not include it, would a possession of seven years under the Smallwood deed and the will of Thomas Gibbs as color mature the title of the defendant to such portion of the territory covered by the deed as was included within the lappage on the Watson grant? It was admitted that the defendant did not occupy the land in dispute north of the line T to 8 before 1867, .nor for the period of twenty-one years, when the statute was running after that time; so that in the contingency mentioned the defendant must rely upon showing title out of the State by the grant to Watson and in himself by possession for seven years under color of title. If prior to 1867 the plaintiffs or those under whom they claim were in the actual possession of any portion of the Watson grant outside of the lappage (which, if the Smallwood deed extended to the line 1 S, would he identical with the loem in quo) and the defendant was in the occupation of some portion of the land embraced in the Smallwood deed but south of the disputed land, the law would, while such was the status, give the constructive possession of the entire lappage; to those holding under the grant, which was the older title, as it would so long as neither party entered and occupied under his title. McLean v. Smith, 106 N. C., 172. “ If one be seated on the lappage and the other not the possession of the whole interference is in the former.” McLean v. Smith, supra: Williams v. Miller, 7 Ired., 186. There was evi-*85(lenco tending to show that the defendant had entered upon the lappage in 1867 and liad since such entry occupied and cultivated some portion of it for more than seven years when the statute of limitations was running. So long as the defendant was seated on it and the plaintiff was not, the possession of the whole lappage was constructively in the defendant if it was embraced in his deed, because the moment he crossed over the plaintiff's line his purpose to claim adversely was unmistakable and his liability as a trespasser to one having a better title was unquestionable. The law therefore would attach the usual penalty for the laches of the plaintiff in failing to maintain his right by an action. Williams v. Miller, supra; Osborne v. Johnson, 65 N. C., 26. If the plaintiff during the time when the defendant so occupied the lappage had also been seated on it, the better title would have drawn to the former the constructive possession of all of the interference except so much as was embraced within the actual enclosure of the defendant. Until the defendant crossed the south line of the lappage, however, and made himself a trespasser upon the territory embraced within the Watson grant the plaintiffs could maintain no action against him, because he might have shown good title up to their line and that he had not ventured beyond. Though as a rule a man is presumed to claim to the outside boundaries of his jmpor title (McLean v. Smith, supra; Ruffin v. Overby, supra), yet that-presumption does not disturb the constructive possession of one holding by superior title. The sufficiency of possession to mature title depends upon the liability of the occupant to an action of trespass. “This is the test.” Osborne v. Johnson, supra. It would be hard measure if the defendant could, by a possession for seven -years south of the locus -in quo, acquire title to the lappage, which is the locus in quo, without incurring liability as a trespasser upon *86it. Where the boundaries of two grants or deeds lap upon each other the constructive possession of his entire boundary remains in him who lias the better title, even without any actual possession whatsoever, until the claimant under the junior grant occupies the lappage. When such claimant enters into the exclusive occupation of the interference he extends his constructive possession to the outside limits of his deed, but if the grantee under the older title seat himself upon it at any moment before the end of the statutory period, he in turn extends his constructive possession to the whole interference, except the possessio pedis of the other. If the defendant had entered upon the land in dispute and held adversely so as to subject himself constantly to an action his title would have matured in seven years, since' he could have availed himself of the plaintiff’s grant to show title out of the State. Gilchrist v. Middleton, 107 N. C., 663.
We think that the learned .Judge who tried the case below erred when ho instructed the jury that a possession south of the line 8 13 for seven years was sufficient to ripen defendant’s title under the Smallwood deed. It is perhaps well to add, in view of the fact that the point may be raised on another trial, that the map offered was not competent as evidence per se, but could be used bjr a witness under examination to explain and elucidate his testimony. Dobson v. Whisenhant, 101 N. C., 645. For the error in the instruction given as to the effect of a possession south of -the line 8 to B and in refusing the instruction asked upon the same subject a new trial is granted. New Trial.
