The sole question in this case is whether the payment of the bond and mortgage of Tally and Carr have operated as a satisfaction, pro tanto, of the bonds and mortgages of the defendant Weir, held by the plaintiff, which had become due before' such payment was made, and we are of opinion that it did. The assignment of the bond and mortgage of Tally and Carr having been made as collateral security for the payment' for the other bonds and mortgages held by the plaintiff, the assignor, Weir, no doubt retained an equitable interest therein, notwithstanding the assignment vested the legal title thereto in the plaintiff. Such equitable interest passed to the receiver, Otis, by virtue of the proceedings supplementary to execution set forth in the case. The relation between Weir and Beceiver Otis, respectively, and the plaintiff, was that of pledgeor and pledgee, and gave to the former the right to redeem the bond and mortgage of Tally and Carr, by paying the debt for the payment of which these securities had been pledged, and to any surplus that might remain after payment of such debt. But, as that debt greatly exceeded the amount of such securities, no right to a surplus has yet arisen. It is also a principle of equity that one who has several funds to satisfy his demands will be compelled, on the demand of another who has a subordinate lien upon some, but not all, of the same funds, to exhaust the fund upon which he has an exclusive lien, before resorting to the others. But this principle is subject to the qualification that compliance with such demand will not subject the holder of the paramount lien to delay or inconvenience in the collection of his debt, as to risk of loss to himself, or of injustice to other persons. Pom. Eq. Jur. § 1414, and cases cited. We are of opinion that this pri nciple mentioned is not applicable to this case, for several reasons: (1) The general rule is well settled that when a creditor receives payment in due course of an obligation held by him as collateral security for the payment of a debt due him, the law at once applies such payment in satisfaction wholly or in part of the principal debt, (Waring v.
