Baldwin, J.

The defendants owned a parcel of land, subject to two mortgages given to' secure notes bearing interest. They paid the interest accruing on each mortgage until 1893, after which they never paid any on the second, which was given to secure their own note. On the first they paid the interest as it accrued until 1895, and none thereafter. The plaintiff was the son and sole heir of the second mortgagee. In 1895, the insurance on the mortgaged property having run out, he requested the defendants to renew it, but they refused and repeatedly offered to give him a release deed of their equity of redemption, which he declined to accept. They continued in possession of the premises, receiving the rents and profits, until 1903, when the property was sold under a foreclosure of the first mortgage. In 1899, 1900 and 1902, the plaintiff paid the interest accruing on the first mortgage, and the premium for insurance on the property. The defendants did not know of this. The payments were made voluntarily and solely with a view to protect the second mortgage, and not at the defendants’ request.

Under these circumstances, the trial court properly held that the law implied no promise on the part of the defendants to reimburse the plaintiff for his expenditures, nor any ratification which made him their agent in making the pay *577 ments, and that it did not impute to them knowledge that any such payments had been made.

With respect to the defendants, the plaintiff was a mere volunteer. So far as appears, they were under no personal obligation to him or any one else to satisfy the first mortgage. They therefore were within both their legal and their equitable rights when they stopped making the payments for interest and insurance, for which it might call. For the plaintiff to continue them, even if he could be considered as virtually the second mortgagee, would be of no benefit to them. A mortgagee has a right to protect himself, if necessary, by paying interest in default upon a prior mortgage, or any other demand which it was conditioned to secure; but what he thus pays becomes, should he afterwards seek a foreclosure, an equitable addition to the charge of his own mortgage, and the total amount of the incumbrances as against the owner of the equity of redemption, therefore, continues the same. 3 Pomeroy on Equity Jurisp. § 1211 et seq.; Sperry v.

There is no error.

In this opinion the other judges concurred.
