This appeal is from an order making absolute a rule for judgment for want of a sufficient affidavit of defense in an action on a mortgage. The mortgage was payable in four yearly installments and it contained a provision that, in the event of default in payment of an installment or of interest or of taxes on the property mortgaged, the whole of the principal debt should become due. This provision was set out in the scire facias and it was alleged in the writ that default had been made in the payment of an installment of the principal and in the pay*585ment of taxes assessed against the mortgaged premises. No defense was made by the mortgagor. Four affidavits of defense were filed by his trustee in bankruptcy, the terre-tenant, and a rule was taken by him for the production of papers. These affidavits, with the answer to the rule and the copies of the papers produced, make a voluminous record of some forty pages, the details of which it is unnecessary to discuss. The attempt of the defendant was to set up a new agreement, changing the time for the payment of the installments of principal, under which there had been no default in payment. If it be conceded that such an agreement went into effect, and the averment of its delivery appears to have been studiously avoided, the allegation that the taxes for the preceding year were unpaid remains undenied. The fact of the nonpayment of the taxes made the whole of the principal debt due according to the terms of the mortgage, and this without regard to the other question in the case: Williams v. Graver, 152 Pa. 571.

There are two grounds of defense argued that may be briefly noticed. One is that the mortgage had been assigned before suit brought by the plaintiff. This allegation was based on the fact that an unrecorded assignment was produced with other papers by the plaintiff in response to the rule taken by the defendant. But the answer to the rule contained an averment that the assignment had been executed in order to facilitate the carrying out of an agreement which was in contemplation but was abandoned and never went into effect, and that the assignment had not been delivered; that it transferred no right, and that it was in the absolute possession and control of the plaintiff, by whom it was produced. If the defendant had any fears that his knowledge of the existence of an unrecorded assignment exposed him to the danger of a second action, he could readily have resolved the doubt by inquiry of the assignee named.

The second ground is that the averments in the third affidavit of defense of the defendant’s belief that he had a just and legal defense to the mortgage and that he had made diligent inquiry and had not been able to. obtain sufficient in*586formation to enable him to set forth particularly the nature and character of the defense were sufficient to prevent judgment under rule 3 of the court. The section of the rule referred to is as follows: “An affidavit of defense shall be required from executors, administrators, guardians, committees and others sued in a representative capacity: Provided, That an affidavit by the defendant in such cases, stating that he has made diligent inquiry and has not been able to obtain sufficient information to enable him to set forth particularly the nature and character of the defense, but that he believes there is a just and legal defense, shall be deemed a sufficient compliance with this rule.” The court of common pleas has not construed this section to apply to a trustee in bankruptcy and there are obvious reasons why it should not extend to him, since he may possess himself of all the knowledge the bankrupt has. Manifestly we would not be warranted in holding that the court erred in the construction of its rule.

The judgment is affirmed.
