¶2In December, 1876, Draper paid plaintiff six hundred and sixty dollars to be applied on the indebtedness, and, the notes still being in Peden’s hands, plaintiff wrote him, giving directions as to the manner in which the amount should be credited on the notes, also advising him that he had made arrangements with Draper to send directly to him (plaintiff) any payments which he might make in the future on the notes, and that he would advise him (Peden) of any such payments, so that he could make the proper credits on the notes. We are satisfied that plaintiff knew, when he received this payment from Draper, and made the arrangement with him, that the Fisk notes had been surrendered up to Fisk.
¶3The facts with reference to this transaction, then, briefly, are these: Fisk was indebted to plaintiff in the sum of $1,300, and this was secured by mortgage on the farm; Draper, in the purchase of the farm from Fisk, became indebted to him in the same amount. It was agreed between the parties that Draper should become responsible to plaintiff for the amount, and that plaintiff should accept him as his debtor instead of Fisk; and, in pursuance of this agreement, Draper executed and delivered to plaintiff his notes for the amount, and Fisk’s notes were surrendered to him, and plaintiff, with knowledge of that fact, received from Draper the six hundred and sixty dollars, and otherwise recognized him as his debtor.
¶4The effect of this is undoubtedly to discharge Fisk from all liability to plaintiff for the debt. Draper, having con*89traeted with Fisk’s consent to pay the debt to plaintiff, is discharged from his former liability to Fisk and is substituted in Fisk’s stead as plaintiff’s debtor. "We think, therefore, that the district court erred in rendering a personal judgment against Fisk.

¶6It is undoubtedly true that any act which amounts to a payment of the debt also discharges the mortgage. But in this case we think the debt which was secured by the mortgage has not been extinguished. The debt from Draper to Fisk was satisfied by the arrangement between the parties, but the only effect of the arrangement as to the debt from Fisk to plaintiff was to substitute Draper for Fisk as the party personally liable therefor. The undertaking of Draper was, not that he wpuld pay to plaintiff the debt which he owed Fisk, but that, in consideration of being discharged from that debt, he would pay to plaintiff the debt which Fisk owed him. So that the debt now due the plaintiff is the same debt that Fisk secured by the mortgage. And the rule is well settled that the mortgage continues in force until the debt is satisfied. No mere change in the form of the debt, nor (as we think) in the personnel of the debtor, has the effect to discharge it. Sloan v. Rice, 41 Iowa, 465; Packard v. Kingman, 11 Id., 219; Hendershott v. Ping, 24 Id., 134; Watkins v. Hill, 8 Pick., 522; Pomroy v. Rice, 16 Id., 22.

¶8But it is claimed by defendants that the satisfaction of the mortgage, entered of record by Peden under plaintiff’s power of attorney, has the effect to terminate all rights of plaintiff under it. This claim, however, is disposed of by our holding in the former appeal that the power of attorney authorized the. cancellation of the Fisk mortgage only upon the execution by Draper of a mortgage which would preserve and continue the security created by the former mortgage; and to that holding we are content to adhere. The entry of satisfaction, then, was unauthorized, and plaintiff’s rights are not affected by it.
¶9We do not overlook the fact that the mortgage was delivered to Fisk by Peden at the same time that he surrendered Fisk’s notes to him. But as plaintiff had not consented to relinquish his mortgage security, this surrender of the instrument would not have the effect to extinguish it.
¶10At the -time Paine .took his mortgage from Draper, the *91Fisk mortgage was of record, and he was charged with notice of it. The fact that Fisk had been discharged, and Draper substituted as the debtor, does not affect the question. The record if the mortgage which, as we have seen, continues as a security for the debt, was sufficient to advise him of the existence of an encumbrance on the land, and he was bound to take notice of it.
¶11IY. We do not find any evidence that plaintiff ever ratified or approved the act of Peden in entering satisfaction of the mortgage of record. But, on the contrary, it appears that he repudiated the act as soon as he was informed that Peden had entered the satisfaction without taking a new mortgage from Draper.
¶12Y. Some negotiations took place between him and Draper for the purchase by plaintiff of the farm, in satisfaction of the debt in question, but it is clear from the evidence that they never entered into a contract with reference to this matter that either could enforce. The evidence of the negotiation is entirely in parol; and, if an agreement was ever arrived at, it was made on a Sunday, and was consequently unlawful. It has never been executed, and could not now be enforced.
¶13The personal judgment against defendant, Fisk, will be reversed, and the case will be remanded to the district court for the entry of judgment even against Draper for the amount of the debt and for the foreclosure of the mortgage, or, if plaintiff elects, such judgment will be entered here.
