¶1This is an action of covenant upon an agreement between Isaac L. McCormick, owner of lot five, block forty-six, East Denver, Yincent D. Markham, trustee, and Helena L. Beck, beneficiary named in a deed of trust conveying said lot, all parties of the first part, and George E. Crater, owner of lot four in said block, party of the second part.
¶2The agreement relates to the building of a brick wall on a line between said lots. The breach assigned is the failure of Crater to pay one-half of the value of the party wall in conformity with the agreement.
¶3Before McCormick had entirely finished the party wall lot five was sold and conveyed by Markham as trustee to Helena L. Beck, the designated beneficiary, and by Helena L. Beck, six months after the trustee’s sale, it was again sold and conveyed to John W. Rogers.’
¶4McCormick and wife, on the same day that Helena Beck conveyed lot five to Rogers, also made a deed to Rogers for the same premises. The several deeds executed respectively by Markham, Mrs. Beck and by McCormick and wife purported to convey the entire party wall, including that part which was on Crater’s premises.
¶5The agreement contained, inter alia, the following stipulations :
¶6“ If the said lot of the said McCormick shall be sold under the trust deed aforesaid, before the said wall is completed, then if the purchaser of said property shall elect to finish and does finish said wall, then and in that event the payment above provided for to be made to said McCormick *198shall on the same terms be made to the purchaser of said property instead of said McCormick.”
¶7Clearly, the purchaser referred to in this stipulation is the purchaser at the trustee’s sale. Mrs. Beck was such purchaser. But she did not elect to finish the wall. In fact she did nothing toward its completion, and therefore can claim no right by virtue of that stipulation. . As Mrs. Beck failed to elect to finish the wall, McCormick, as we interpret the indenture, was at liberty to carry out the agreement according to its terms, after the premises had been conveyed to Rogers, he consenting thereto.
¶8The referee must have found that McCormick, by an agreement between him and Rogers, procured the completion of the wall. That McCormick, through the agency of Rogers, caused the wall to be finished, we think is fairly deducible from the evidence. Whether McCormick carried out his agreement with Rogers is a question with which we now have nothing to do. It is enough to know that by the procurement of McCormick the'wall was completed.
¶9It is, however, insisted that the covenant between the adjoining lot owners runs with the land, and that therefore McCormick having sold his premises is not entitled to sue. Leaving out of view the clause in the agreement in relation to the purchaser under the trust deed, for the reason that under the evidence it need not be considered, we are of the opinion that the covenant is in its nature personal and did not pass with the lot to subsequent owners. Although the authorities are somewhat conflicting upon this point, this we think is the better doctrine. Weld v. Nichols, 17 Pick. 538 ; Ingles v. Bringhurst, 1 Dallas, 367 ; Hart v. Kucher, 5 Serg. & Rawle, 1; Todd v. Stokes, 10 Penn. St. 155; Block v. Isham et al., 28 Ind. 37.
¶10Upon completion of the wall, if built according to- agreement, Crater became personally liable for one-half its value.
¶11Crater’s office was on lot four and within ten feet of the party wall. He also lived on the same lot. Under his eye from day to day the work advanced. The division line be*199tween the lots was located by the city engineer at the instance of McCormick, and with reference to that line the wall was constructed. If there was even a trifling departure from the terms of the agreement, the evidence tends to show that it was not willful nor intentional. There is no pretense that there was a careless or negligent omission, of duty. “To the satisfaction and acceptance of Crater” the wall, it is testified, was completed. While the work was in progress, Crater never intimated that there was the slightest deviation in any particular from the terms of the contract.. If credit be given to the testimony of McCormick, the agreement — reference being had to the issues formed — was carried out by him in all respects substantially according to its terms, and more than this cannot ordinarily be required.
¶12There was a conflict of evidence as to the true location of the division line, and of the party wall thereon, but considered as a whole, the referee’s finding cannot be said to be unsupported by evidence.
¶13The finding of a referee as to its conclusive effect stands as the verdict of a jury.
¶14The demurrer to the sixth plea was properly sustained. It was drafted on the assumption that the covenant run with the land. Even if a remote subsequent grantee should be entitled to recover one-half the value of the wall, such recovery could only be had in the event that he should under the indenture elect to finish, and should in fact finish the wall. But there is no such allegation in the plea.
¶15Nor was there error in overruling the motion for a new trial. The chief ground of the motion relied on was newly-discovered evidence, which it is claimed came to the knowledge of the defendant during the progress of the trial. This evidence relates to the thickness of the party wall between the second and third floors.
¶16The pleadings were such that no advantage could be taken of this alleged defect. The thickness of the wall from its base to its summit was not put in issue. It is a rule that *200“whatever has been, admitted on both sides in the pleadings cannot be contradicted either in the subsequent pleadings or even by the verdict. For neither party can retract what he has before conceded on the record ; and the jury have no authority to find any other facts than such as are put in issue.” Gould’s Pleadings, § 168. Says Stephens on Pleadings, p. 217: “The effect of such admission is extremely strong, for, first, it concludes the party, even though the jury should improperly go out of the issue and find the contrary of what is there confessed on the record,- and, in the next place, it is to be remarked that the confestion operates not only to prevent the fact from being afterward brought into question in the same suit, but is equally conclusive as to the truth of that fact in any subsequent action between the same parties.”
¶17But it is insisted that as the alleged failure to construct the wall of the required thickness between the second and third floors was unknown to the defendant until it was disclosed at the trial, the motion should have been allowed to enable the defendant to interpose an additional plea raising an issue under which-the newly-discovered e vidence might have been available.
¶18By the use of ordinary diligence before the trial, the defendant could have ascertained the- thickness of the wall and formed the issues accordingly.
¶19Had he been half as vigilant in this respect as he was in his effort to prove that the plaintiff had mistaken the true division line by the fraction of an inch, there would have been no occasion to raise this question by a motion for a new trial.
¶20The judgment of the court below is
¶21Affirmed.
