(after stating the facts as above).
A motion is made to dismiss the writ of error, on the ground that the plaintiff in error has paid and satisfied the judgment. The motion must be denied. One who voluntarily pays a judgment is not precluded from taking an appeal therefrom. County of Dakota v. Glidden, 113 U.S. 222, 5 S.Ct. 428, 28 L.Ed. 981; Erwin v. Lowry, 7 How. 172, 12 L.Ed. 655; O’Hara v. McConnell, 93 U.S. 150, 23 L.Ed. 840; Edwards v. Perkins, 7 Or. 149.
Error is assigned to the refusal to strike from the complaint those allegations which set up as elements of damage the payment of traveling expenses and loss of time and loss of opportunity to earn money by the defendant in error, incidental to his efforts to obtain title to his mining claims and his prosecution of his suit. Those allegations should have been struck from the complaint. But the defendant in error suffered no prejudice from the denial of his motion. No evidence whatever was offered to the jury to support the allegation as to the first item of damages. Nor did the court submit to the jury that item for their consideration. After the verdict was rendered, the court struck from the amount thereof $3,525, a sum more than sufficient to cover the amount of the other objectionable items. It should be presumed that, in so reducing the amount of the verdict, the court, intended to and did ex-*28elude therefrom, all items of damage which had been illegally submitted to the jury. Johnson v. Johnson, 104 Ky. 714, 47 S.W. 883. Unless it can be seen that prejudice has resulted from error of the trial court, prejudice will not be presumed.
But it is said that the court erred in instructing the jury concerning the loss sustained by defendant in error as the result of his purchase of a boiler. The court instructed the jury to take into consideration the fact, if they so found from the testimony, that the plaintiff purchased a boiler and transported it to the claims, and said: “And the same method should be employed in computing the damages in this case, if you should find said boiler was purchased, and that the plaintiff was prevented from using the same, for the price of such boiler.”
This it is contended was equivalent to charging the jury that they might find for the plaintiff in the action damages measured by the purchase price of the boiler. It was evidently not so understood at the time, and no exception was taken to the instruction, and no assignment of error is based thereon. It is obvious that the language of the court is not correctly reported. Elsewhere the court clearly instructed the jury that the measure of damages as to the boiler and other machinery was the interest on the money invested therein during the time that the plaintiff was kept out of possession by reason of the acts of the defendants.
The court instructed the jury as follows: “If you find from the evidence that the plaintiff could have worked said mining claims at a profit during the winters of 1907 and 1908 and of 1908 and 1909, and the summers of 1908 and 1909, he would be entitled to legal interest at the rate of 8 per cent, per annum upon the profits that he would have made, if any, during the period that he was kept out of the use of the money.”
Error is assigned to this instruction, and to the admission of certain testimony, as follows: -The defendant in error was asked if he had made any preparations for mining the property in the way of purchasing mining machinery and supplies. He answered that he had bought a boiler in Tacoma, for which he paid $300, and had shipped it to Alaska. He was asked what arrangements, if any, he had *29made in the winter of 1908 and 1909, and the spring of 1909, with the Fairhaven Water Company to work the ground, if he could have obtained possession thereof. He answered that he had arranged with the company to work the ground, on a royalty of 40 per cent., with hydraulic elevators; that the company had a supply of water, ditches, and pipe lines in such manner that it could have worked the ground; that in the summer of 1910 the company did work the ground, and paid him a royalty of 40 per cent, on $36,358.35 taken therefrom, and in 1911 mined the ground, and paid him a royalty upon more than $70,000.
It is contended that this evidence should have been excluded, for the reason that it does not afford competent proof of the profits which would have accrued if the claims had been mined during the time mentioned, and because there is no evidence that the defendant in error could or intended to work the ground in the summer of 1908. The reasons suggested for the exclusion of the evidence are not sufficient. The defendant in error was there to work the mining property, if he could get possession of it. The plaintiff in error inequitably excluded him from the possession, and during the period of such exclusion the defendant in error might have mined the ground, and he testified that he had made an arrangement to mine it with the corporation which subsequently did mine it. The position of the plaintiff in error seems to be that the owner of a mining claim suffers no damage by being prevented from working it, for the reason that the gold is all there in the ground, and will be there when he does get the opportunity to work it, or that the measure of his damages is, at most, the interest on the purchase price of the mine. But the mineowner is entitled to the benefit of the use of the money which he can take from his mine, and the plaintiff in error has no ground to complain in this case that the court admitted the evidence which was objected to, and- instructed the jury that they might charge him with legal interest on the profits which the defendant in error might have made from the mining claims during the period of his exclusion from the possession thereof.
The judgment is affirmed.
