Field, C. J. and Baldwin, J. concurring.

This is an action to recover the amount of a promissory note for four thousand dollars, with interest at the rate of two and a half per cent, per month, and to foreclose a mortgage executed to secure its payment. On the trial of the case, the defendants offered to prove that from a certain time the interest had been reduced, by a parol agreement, to one and a half per cent, per month. The rejection of this proof is assigned as error.

The general rule is, that extrinsic verbal evidence is not admissible to contradict or vary the terms of a written agreement. This rule is not infringed by the admission of such evidence to prove that the written agreement has been discharged, or to establish a new and distinct agreement, upon a new consideration, which takes the place of, and is a substitute for the old. In the latter case, however, it must appear that the old agreement is rescinded and abandoned, and it is not competent to show by parol the incorporation of new terms and conditions. It is obvious, too, that the new agreement must be valid in itself, and such as may he made the basis of an action.

Under our statute, parol evidence is not admissible, in any case, for the purpose of establishing a claim to interest beyond the statutory rate. Such a claim must be evidenced by writing, or it is invalid, and cannot be enforced. The effect of the proof in this case would have been to establish a contract upon which the plaintiff could not recover. ¡No action could be maintained upon it, and no effect can he given to it as a modification of the terms of the original agreement.

The other points in the case are without merit, and the judgment must therefore be affirmed.

Ordered accordingly.
