¶1Cooper, Farley, and Bamum—assignors of the plaintiff— contracted in writing with the defendants to furnish certain materials for, and to perform certain work upon, the Stonewall mine, mill, and mining property, situate in San Diego County, in consideration of which the defendants agreed to pay them the sum of one thousand seven hundred dollars— eight hundred dollars during the progress of the work, “ and the balance of nine hundred dollars to be paid out of the first proceeds of the mine, after deducting expenses.” The materials were furnished and the work completed by Cooper, Farley, and Bamum, and accepted by defendants on the twelfth of May, 1880; but the latter failed and refused to work the mine, or to pay the balance due on the contract.
¶2That the contract contemplated that the defendants were to work the mine “ out of the first proceeds of which, after deducting expenses,” the balance was to be paid, does not admit of doubt. And we are of opinion that their failure and refusal to commence to work it within a reasonable time after the completion and acceptance of the labor and materials bestowed on the property, rendered them liable for the balance due therefor.
¶3. The Court below, however, erred in allowing the plaintiff interest from May 12,1880. The defendants were entitled to a reasonable time after the completion of the repairs within which to commence to work the mine, and until they had made default, the plaintiff was not entitled to interest. The Court below did not find definitely when such reasonable time elapsed, but that it elapsed “between the completion of said contract (May 12, 1880), and the commencement of this action (December 24,1880).” From its expiration the plaintiff is entitled to legal interest—a fortiori from December 24, 1880. The former can not be awarded the plaintiff on the record, because of the omission in the finding above noticed.
¶4It is, therefore, adjudged here that the judgment and order of the Court below be reversed and the cause remanded for a new trial, unless the plaintiff, within twenty days after the filing of the remittitur in the Court below, files his consent *486in writing to the modification of the judgment by striking therefrom the amount of interest allowed him prior to December 24, 1880, in which event the Court below is directed to modify the judgment accordingly, and as so modified it is affirmed.
