¶1In December, 1868, Graham, who was a banker, and then believed to be solvent, let plaintiff have certain notes and a judgment, amounting with interest, to something over two thousand dollars, upon responsible parties, and at the same time received from plaintiff some money. As to the true nature of this transaction the parties differ very widely. Plaintiff says he bought the notes and judgment, paying therefor $750 : and that said transaction was in no manner connected with the $7,000 note. Graham¡ however, says, that being in great need of money, he negotiated these securities, receiving so much money ($262.50), plaintiff depositing at the same time, to help him in his stress, $500, the balance (some $1,820) being paid as interest on the large ($7,000) note, the same being calculated at about three per cent per month.
¶2Looking at the entire testimony, we think it propon*516derates largely in favor of defendants’ theory of the transaction. Certainly, there can be no just ground for claiming that the finding, in this respect, is so far against the evidence as to warrant our interference. It is most unreasonable that paper of this amount, well secured upon parties abundantly good, should be sacrificed as claimed by plaintiff. Then, they had talked the day before, according to plaintiff’s own testimony, about taking these notes toward the interest, estimated at about three per cent per month, and it is but too evident that this was a scheme devised by him to avoid, if possible, the charge or claim of usury. The real transaction, when stripped of its subterfuges and covering, was that Graham parted with the paper because he got some money to assist in meeting pressing calls upon him, and knew at the same time he was answering, without its being so said in words, the usurious exaction of this creditor. And this the creditor knew just as well, and with this understanding —well understood, rather than expressed, perhaps — he took the paper. The court did not err, therefore, in allowing a credit for the balance of this paper, after deducting the moneys received on the same.

¶4Every proposition of law stated by appellee’s counsel *517—certainly every one in the remotest degree applicable to the facts of this case — may be conceded, and still this judgment should be reversed. We refer to some of them. Good faith is exacted from the creditor to the surety, at the time of the contract, and all the subsequent transactions touching the debt. If there is a departure from this the surety will be released. So, if by the creditor’s fraudulent conduct the surety is lulled into groundless confidence, and he is prevented from obtaining indemnity, he is discharged. A binding contract with the principal, with knowledge of suretyship (and this knowledge is undenied in this case), without the consent of the surety, which varies the terms of the original undertaking to his prejudice, discharges the surety, and a material variation would of course be presumed to be prejudicial. A binding agreement enlarging the t:me of the performance would have this eifeet. It is not necessary that the debt should be actually suspended to produce this result. A valid agreement to suspend is sufficient; and this, whether the agreement be one upon which the principal has a remedy either at law or equity.
¶5These rules are conceded, and we take no time to discuss either their reason or propriety, or to examine the cases in their support. But while it may, in morals, perhaps, be unjust for the creditor, by his delay, without fraud or collusion, to increase the liability of the surety to pay the debt, it is not true that mere delay, though followed by the insolvency of the principal, will discharge the surety. The delay to sue Graham, therefore, did not release' the sureties. And this, because they were not misled; because they themselves were in default; because it was their duty to pay ; because they could judge as well as plaintiff of the dangers of delay; and because by notice they would have stimulated plain*518tiff to activity, and if after that he delayed, the peril was his own.

¶8And as to the implication arising from the alleged advance payment of interest, we have only to say, admitting the rule for which counsel contend, that it cannot apply, when it would defeat the clear intention of the parties. If the creditor manifestly intends to hold the sureties, and it is obvious that he refused to extend the time, the simple act of the advance payment of interest will not justify the influence or implication that there was such an agreement.
¶9Let the judgment be reversed, and cause remanded for trial de novo.
¶10Eeversed.
