22 FEDERAL nmronrmn. Sur. § 370; Hayes v. Ward, 4 Johns. Ch. 129; Baker v. Briggs, 8 Pick. 129. But this equitable principle is not to be applied so as to produce inequitable results, as is often the case with the operation of the rule that arbitrarily releases a surety from his liability where the creditor has given the principal an extension of time, without reference to the fact of whether the surety was or could be in any way injured thereby. Therefore, where it appears that the surety was in no way prejudiced by the release of the debtor’s property, because the property of the surety would be needed to satisfy the debt in any event, he cannot complain of such release. The only person who is injured is the creditor. The contract of the surety in this case was that her property might be taken to pay her husband’s debts, provided they were not paid by him, or his property included in the mortgage was insufficient for that purpose. As thedebt was not paid by the debtor, and his prop- erty pledged for its payment has proved insufhcient for the purpose by a sum greater than the value of the surety’s property, it is not apparent how the surety could be wronged if the creditors had re- leased the whole of the debtor’s property without any reduction of the debt, and enforced the mortgage against her property alone. Brandt, Sur. § 380; Neimcewicz v. Gaim, 3 Paige, 642. * The cases of Mayhew v. Boyd, 5 Md. 102, and Ives v. Bank, 12 Mich. 362, cited by counsel for the defendants on this question, are not in point. They both turned on the construction of the contract between the creditor and surety, and not the application of the equi- table rule in question; and I may add that the Maryland case carries the doctrine of the arbitrary right of the surety to be discharged from his obligation by a mere extension of time to the debtor, whether he is thereby prejudiced or not, to the very verge, and manifestly so as to do injustice to the creditor in the particular case. Other technical defenses to this suit are made in the answer, and reserved in the stipulation of April 6th; and-- V First. The creditors, from time to time, for a suiiicient consid- eration from Cross, extended the time of payment of these [notes, whereby the property of the surety was discharged from all liability thereon. This part of the answer is made on information alleged to have been derived from Thomas Cross in his life-time, concerning matters which transpired when the defendants were children. The state- ment of the matter is very vague and general, without a single veri- . fying circumstance of time, place, amount, or name, except that of a dead man. Such an allegation is of little force as evidence, even if made in response to the bill. 1 Daniell, Ch. Pr. 846, note 1. But it is not made in response to any allegation in the bill. It is new matter set up as a defense. The burden of proof to establish it is on the defendants, and their answer is not evidence in support of
