The boundary called for in the deeds of the plaintiff was “ Shirley line,” and in the deed on which the defendant relied, “ Lunenburg line.” These words urould be equally satisfied by the line which was in law the boundary between the two towns, or by a line which was universally considered and reputed to be such boundary at the time of the making of the deeds in question. Evidence was introduced at the trial that the legal line between the towns differed from what it was universally supposed to be, and thus disclosed a latent ambiguity, which could only be cleared up by oral evidence. The case comes exactly within the familiar maxim, as long ago expounded by Lord Bacon. Ambiguitas verborum latens verificatione suppletur; nom quad ex facto oritu/r ambiguum verificatione facti tollitur. “ Ambiguitas latens is that which seemeth certain and without ambiguity for anything that appeareth upon the deed or instrument, but there is some collateral matter out of the deed, that breedeth the ambiguity.” “ As if I grant my manor of S. to I. F. and his heirs, here appeareth no ambiguity at all; but if the truth be that I have the manors both of South S. and North S. this ambiguity is matter in fact; and therefore it shall be holpen by averment, whether of them was that the party intended should pass.” Bac. Max. reg. 25.
In the case of Cook v. Babcock,
In the case at bar, the jury were therefore rightly instructed that, although the presumption upon the face of the deeds would be, that they conveyed to the true record line, yet that line was not necessarily the boundary between these parties, but if a dif
But in one particular the instructions of the learned judge who presided at the trial were not sufficiently guarded. The plaintiff had offered evidence that from 1830 to 1848 the line to which he claimed had been perambulated as the town line between Shirley and Lunenburg; and the jury, besides the instructions already mentioned, were instructed that, “ if the towns of Lunenburg and Shirley had adopted a line, different from the true one, as the line between the towns, the deeds would convey to that line, if there were no monuments to fix the line intended.” This instruction was erroneous. The towns had no power to alter the boundary line between them. The perambulations of the boundaries of the towns by the selectmen in the execution of the duty imposed upon them by law were doubtless competent, but they were not conclusive, evidence of the line intended by the parties.
