delivered the opinion of the court.
Appellant was sued upon two notes for the purchase price -of land, and a lien sought to be enforced. One of the notes ■is as follows:
‘ ‘ On or before the first of March next, I promise to pay JB. B. Elliott the sum of two hundred and eighty-four dollars and twenty cents, for value received, this 22d November, 1873.”
The other note is in the same form, and the same date, ‘‘but made payable on the first of March, 1875.
To this action appellant pleaded payment, except as to ■■the interest, and as to that, he pleaded an agreement entered into at the time of the execution of the notes with B. B. Elliott, to the effect that no interest was to be charged. On The issue as to the agreement in -regard to the payment of .interest, there being no allegation of fraud or mistake, oral *278evidence was heard, and the main question is as to the competency of such evidence.
The -rule that parol evidence is not admissible to contradict or vary a written instrument evidencing an agreement is subject to many exceptions, and many instances have beem declared within the rule which clearly do not belong there. The rule properly applied was intended to reach cases where the parties purport in the writing itself to set forth their agreement, or where the undertaking is inferable from the terms used in the writing. It ought not to apply to mere' legal presumptions, which in effect add new terms to the5 contract as expressed between the parties, and it has not been so applied in this state. It is held, for instance, that one who signs a promissory note, the body of which denotes that all who execute it do so as principals, may show by parol that he signed as surety, and the other parties to the.note are principals. In such a case the rule is encroached upon more directly than in the case under consideration. There the usual language in notes signed by more than-one person, “we promise,” followed by signatures without' designation as to whether principals or sureties, would', seem to import that all were equally bound, and stood in the same relation to the payee. Here there is an entire want of language to express, even by inference, an undertaking to pay interest. The undertaking is purely the offspring of legal presumption arising, not from the language or terms of the contract, but from the absence of language indicating such an intention. It has been held in this state, that while-an indorsement in blank of a note implies an undertaking on the part of the indorser to pay in the event the maker does, not, yet parol or extrinsic evidence is admissible to show; that the assignment was without recourse. (Butler v. Sud*279duth, 6 T. B. Monroe, 543 ; Wharton on Evidence, sections 952 and 953; Parsons on Notes and Bills, volume 2, page 519-)
We are of the opinion that the evidence as to the agreement in regard to interest is competent.
The evidence, however, does not appear to clearly establish the existence of the agreement. The evidence principally relied upon to support the agreement is that of one witness, who states that ‘ ‘ after the notes were executed, B'. B. Elliott remarked that John thought he had charged him a large price for the land, and that he thought that the time upon which he let John have the land was quite a consideration; that he was to have his own time in which to pay for it, without interest.” The notes were due in one and two years, and of course bore no interest until due; so that the term “without interest” may have applied to the time intervening before maturity. This evidence is rebutted by various statements of B. B. Elliott, tending to show that his understanding was that the notes bore interest. Under these circumstances, we do not feel authorized to disturb the judgment, and it is therefore affirmed.
