after stating the case as above, delivered the opinion of the court.
Few things have been the subject of'more difference of opinion and conflict of decision than the’ nature and extent of the right of a mortgagee of real estate against a subsequent grantee who by the terms of the conveyance to him agrees to assume and pay the mortgage.
All agree that the grantee is liable to the grantor, and that, as between them, the grantee is the principal and the grantor. *190 is tbe surety for the payment of the mortgage debt. The chief diversity of opinion has been upon the question whether the grantee does or does not assume any direct liability to the' mortgagee. -
By the settled law of this court, the grantee is not directly liable to the mortgagee, at law or in equity; and the only remedy of the mortgagee against the grantee is by bill in equity in the right of the mortgagor and grantor, by virtue of the right in equity of a creditor to avail himself of any security which his debtor holds from a third person for the payment of the debt.
Keller
v. Ashford,
The question whether the remedy of the mortgagee against the grantee is at law and in his own right, or in equity and in 'the right of the mortgagor only, is, as was adjudged in
Willard
v.
Wood,
above cited, to be determined by the law of the place where the suit is brought. By the law of Illinois, where the present action was brought, as by the law of New York and of some other States, the mortgagee may sue at law. a grantee who, by the terms of an absolute conveyance ^rom the mortgagor, assumes the payment of the mortgage debt.

Burr
v.
Beers,
The case is thus brought' within the well settled and familiar rule that if a creditor, by positive contract with the principal debtor, and without the consent of the surety, extends the time of payment by the principal debtor, he thereby discharges the surety; because the creditor, by so giving, time to the principal, puts it out qf the power of the surety to consider whether he will have recourse'to his remedy against the principal, and because the surety cannot have the same remedy against the principal as he'would have had under the original contract; and it is for the surety alone to judge whether his position is altered for the worse. 1 Spence Eq.

v.
Stewart,
In the case at bar, the mortgagee, immediately after' the absolute conveyance by the mortgagors, was informed of and assented to that conveyance and the agreement of the grantee to pay the mortgage debt, and afterwards received interest on the debt from the grantee; and the subsequent agreement by which the mortgagee, in consideration of the payment of a sum of money by the grantee, extended the time of payment *192 of the debt, was made without the knowledge or assent of the mortgagors. Under the law of Illinois, which governs this case, the mortgagors were thereby discharged from all personal liability on the notes, and the Circuit Court rightly refused to enter a deficiency decree against them.
Deeres affirmed.
