Y., sell said lands, and apply the proceeds towards the payment of the said indebtedness to him, said Sippel, and towards the interest thereon, ■and return on demand to said Bommer any surplus that may remain after payment of said debt and interest; and, if the proceeds of said sale shall not be sufficient to pay said debt and interest in full, the said Bommer hereby agrees to pay said Sippel any balance due him on demand.” That, pursuant to said agreement, this plaintiff did, on January 6, 1896, pay to said defendant the sum of $40.21, to apply on his indebtedness to said defendant, as stated in said agreement. That this defendant, claiming that this plaintiff had defaulted in making some of the payments called for by said agreement, on or about the 17th day of March, 1896, served notice on said plaintiff that he would sell the said premises, pursuant to said agreement, on the 27th day of March, 1896. That on said last-named day said premises, and all of them, were sold at auction, subject to a first mortgage on said premises, amounting to $1,400, and subject to the taxes thereon, for the sum of $3,400, which sum was bidden by said defendant, who purchased said premises at said sale for that amount. That the amount of the indebtedness of this plaintiff to said defendant on the day of said sale was the sum of $2,436.83.

That no part of said amount has been paid, although demand therefor has been duly made. Wherefore plaintiff demands judgment against defendant for the sum of $963.17, with interest thereon from March 27, 1896, besides the costs of this action.
