It appears from the undisputed evidence that the plaintiff had been in possession of the N. E. \ of the N. W. J of said section, under a deed of the same, for over thirty years; that there was a fence on the south line of it; that the defendant owned the S. E. \ of the same quarter section; that the defendant came upon the plaintiff’s forty within the said fence, and there built another fence; and that is the trespass complained of. It is true the plaintiff testified that he lived upon the N. E. J of the section; but, obviously, this was a mere inadvertence, for he testified that he had a deed of the premises, which he produced, and that covered the N. E. J of the N. W. J of the section. All parties, manifestly, treated the misstatement as a mere inadvertence. This being a mere action of trespass, the plaintiff, prima facie, established his title to the forty by proving that he had been in possession under a *526deed claiming such title for more than thirty years. McLawrin v. Salmons, 52 Am. Dec. 563, and notes; Plume v. Seward, 60 Am. Dec. 599, and notes; Knoth v. Barclay, 6 Pac. Rep. 924; Bates v. Campbell, 25 Wis. 613; Wadleigh v. Marathon Co. Bank, 58 Wis. 552.
The undisputed evidence showed that the onty trespass proved or claimed upon the trial was the building of a fence about two and a half or three rods north of the old fence upon the boundary line of the plaintiff’s inclosure, and hence in the possession of the plaintiff. The act of trespass upon that inclosure was not disputed. The defense relied upon is that the complaint not only included the forty in the possession of the plaintiff, but another adjoining forty, in the possession of the defendant. The defendant’s theory is that, upon. the answer being filed, the plaintiff should have newly assigned, so as to have excluded from his description all land except what was in his actual possession, as under the old practice. Ellice v. Boyer, 8 Wend. 503. Since that decision it has been frequently held in New York that such new assignment was not necessary nor allowable under the Code. Stewart v. Wallis, 30 Barb. 344; Shull v. Green, 49 Barb. 311; Locklin v. Casler, 50 How. Pr. 43. The same rule must prevail here, since we, in effect, adopted the same Code. Sec. 3626, R. S.
The case was commenced in justice’s court. Had the defendant only pleaded title to the forty in his own possession, the plaintiff might have amended his complaint, as indicated in Shull v. Green, supra; or, possibly, the circuit court might have ordered the complaint made more definite and certain, under sec. 2683, R. S. There was no necessity of any plea of title, as held in the same case. If the complaint was not sufficiently explicit to raise the direct issue, the defendant should have demurred. Subd. 6, sec. 3626, R. S. Then, if the court had deemed the objection well founded, it would have ordered the complaint amended. *527Subcl. 7, sec. 3626, E. S. The defendant having pleaded title to all the premises described in the complaint, and having failed to maintain his plea as to the forty upon which the trespass was committed, he cannot escape the liability disclosed upon the trial of the merits, by the technical objection to the mere form of the complaint.
By the Gourt.— The judgment of the circuit court is affirmed.
