Hillyer for Respondents.

Ho clear case of a latent ambiguity ever existed.

The evidence excepted to was proof by plaintiffs, offered to show in which sense the parties used this term, by showing: First, the usage upon Forest Hill, generally, in speaking of a course ; Second, a con- . *196 versation between plaintiffs and defendants showing6how they understand it.

The books are full of eases sustaining the admissibility of each of these classes of evidence in similar cases. We shall refer to only a few.

1st. As to usage and custom of the particular district, 1 Greenleaf on Ev., secs. 292 and 295. The author in this last section speaks of the present case at bar — a word having two meanings,- one technical and one common. C. and H., Notes to Phillips on Evidence, part 2, vol. 4, p. 505, part 2, note 954; Ashton v. Insurance Co., 7 Cowen, 202 ; 12 Wendell, 573 ; 2 Sumner’s Rep. 569. In this case, Judge Story says parol proof may be admitted to ascertain the true meaning of a particular word, or words, in a given instrument, when the word or words have various senses — some common, some qualified, and some technical. 3 Barn. & Adol. 728 ; 4 N. & M. 602.

2d. As to the admissibility of the conversation between the parties to prove their understanding of the term. Waterman v. Johnson, 13 Pick. 261 ; Stone v. Clark, 1 Metcalf, 380; Birch v. Deipster, 4 Camp. Rqp. 385 ; Gray v. Harper, 1 Story’s Rep. 574 ; Ballenger v. Eckett, 16 Levy & Rowel, 422 ; Selden v. Williams, 9 Watts’ R. P. 14.

The above cases are all directly to the point, and sustain the admission of the evidence. Should the Court desire to look further, we cite : Doe ex Denn Gord v. Nud, 2 M. & W. 129 ; Osborne v. Wise, 7 Carr & Payne, 761; 5 Pick. 34 ; 8 John. R. 116; 1 Mason, 10 ; 4 Hemming & Mumford, 283 ; 3 Rand. 83 ; Woods v. Lee, 5 Monroe, 59 ; 5 Mills & Law. R. 275; C. & H. Notes to Phillips, part 2, vol. 4, p. 535.

The Court will notice that the evidence was introduced, not to show what agreement the parties intended to make, hut to show what agreement they did make.

The thing to be proved being, “ how did the parties understand this term when they used it,” can there be any better evidence of this than direct admissions by Phillips, one of the defendants, as to how it was understood ?

The distinction in all the cases is this: you are not allowed to *197 prove an express intention different from the agreement, or to vary it; but are allowed to prove, by any competent evidence, how the parties understood the ambiguous term.

As to the affidavits of Marshall, one of defendants, concerning what Hoffman will testify:

1st. The Court cannot consider Marshall’s affidavit, but Hoffman’s should have been procured. Vol. 3, Gr. and W. on Hew Trials, 1,065.

Baldwin J., concurring.

This is an action to recover damages for an alleged trespass upon the mining ground of the plaintiffs. The claims of the parties adjoin each other, and in June, 1857, the parties entered into a written agreement as to the dividing line between their claims, describing the same as commencing at a designated point, and “ running thence north twenty-three degrees and fifteen minutes west, six hundred and forty-three feet to apiñe stakeand “ thence north forty-five degrees west to Devil’s canonand the principal question presented by the record relates to the admissibility of parol evidence to show that the last course of the dividing line thus agreed upon was run according to the magnetic and not the true meridian. It appeared, from the evidence allowed on the trial, that it was the general custom at Forest Hill, where the ground in controversy is situated, to run boundary lines by the magnetic meridian, and from the testimony of a witness present at the execution of the agreement, that it was understood the line was to run “ the way the needle points.” It is true, parol evidence is inadmissible to contradict or vary the terms of a written agreement; but we do not perceive that the rule was violated in the present case. It was not to contradict or vary the meaning of the term north that the evidence was admitted, but to ascertain the sense in which it was used by the parties. The term has two meanings, one common and the other technical. Unprofessional men generally mean, in stating courses, the lines indicated by the compass, without making any allowance for variation in the needle ; and even professional Surveyors, as appears from the evidence in the case, would not consider the true meridian as intended, unless specially so informed.

*198 The language of every instrument should be so construed, if possible, as to effectuate the intentions of the parties; and to ascertain the meaning attached to particular words, when such words are used in vari-' ous senses, parol evidence is perfectly legitimate. And this evidence is received to explain, and not to contradict or vary the written language. The patent ambiguity, which according to the rules of Lord Bacon cannot be aided by averment,, arises from uncertainty upon the face of the instrument in the application of the terms used, and not from uncertainty in the meaning of the terms themselves, when those terms are susceptible of two meanings. (See 2 Parsons, 69 , and note.) In the present case the ambiguity lies in the word north; and yet it is not within the rule laid down by Bacon. It belongs to that “ intermediate class of cases,” of which Mr. Justice Story speaks in Peisch v. Dickson, ( 1 Mason, 11 ) “ which partake of the nature both of patent and latent ambiguities ; and that is,” where the words are all sensible and have a settled meaning, but at the same time consistently admit of two interpretations, according to the subject matter in the contemplation of the parties. In such a case, I should think,” says the Justice, “that parol evidence might be admitted, to showthe circumstances'under which the contract was made and the subject matter to which the parties referred. For instance, the word 1 freight ’ has several meanings, in common parlance ; and if by a written contract a party were to assign his freight in a particular ship, it seems to me that parol evidence might be admitted of the circumstances under which the contract was made, to ascertain whether it referred to goods on hoard of the ship or an interest in' the earnings of the ship ; or in other words, to show in which sense the parties intended to use the term.” (Goddard v. Bullow, 1 Nott & McCard; Smith v. Wilson, 3 Barn. & Adol. 728 ; Heald v. Cooper, 8 Greenl. 32; Clayton v. Gregson, 4 Rer. & Man. 602.)

And Cowen and Hill, after referring to the illustration given by Mr. Story, observe that this and other instances of a kindred character “ fall exactly within the general definition of a patent ambiguity. The terms used have in themselves a doubtful meaning, and consistently admit of more than one interpretation, according to the subject matter in contemplation of the parties. The ambiguity is not latent in *199 any proper sense; it arises from the known infirmity of language ; it is inherent in the instrument; appearing on its face, and evincing a difficulty at the very moment of perusal. And yet it admits of explanation.

“ It will not do to say, therefore, that a patent ambiguity (meaning thereby merely an ambiguity patent or appearing on the face of the instrument) cannot be explained by evidence aliunde; though such remarks are frequently found in the books.” (Notes to Phillips, part II, note 269.)

The motion for a new trial was properly overruled. The position of the boundary line was the principal question in the ease, and upon this point several surveyors were examined, and upon their conflicting testimony the jury passed. The subsequent survey of one of the surveyors would only have corroborated the testimony of the defendants’ witnesses, and correspondingly weakened the testimony adduced by the plaintiffs. We do not perceive that it would, taken in connection with the different starting point from the first survey, have materially changed the result.

Each of the surveyors testified to using the utmost care, and each was of opinion that his survey was correct. The Court below was in a better position to judge of the effect of Brewster’s testimony in the case, and the probable result of his evidence after the second survey, than this Court, and we do not feel warranted in disturbing its action in the premises.

The affidavit of Marshall, as to the testimony which Hofiman would give, should have been accompanied by Hoffman’s affidavit. Hoffman’s absence at his residence at Forest Hill, and the consequent inability of Marshall to obtain the affidavit in time, was not a sufficient excuse for its non-production. If necessary, application should have been made to the Court for additional time to obtain and file it.

Judgment affirmed.
