On the part of the learned counsel for the respondent it is argued that the nonsuit was properly granted, for the following reasons: 1. That the evidence shows that the logs in question were the logs of J. S. Keator, and there is not sufficient evidence given on the part of the plaintiff to show that Keator’s title was divested by the tax sale and vested in the plaintiff; and 2. That the evidence shows that what defendant did in May or June in taking possession of the logs and putting them in the stream again after they had been removed therefrom by the plaintiff in March previous, was done on behalf of the owner, Keator.
We are inclined to think that if the proofs in the case had clearly established the fact that the removal of the logs by the defendant in June had been under the direction of Keator, the plaintiff would have failed in his action, for the following reason: The proof that he bought the logs at a *622sale made by the town treasurer for the nonpayment of taxes assessed against Keator was not sufficient evidence to show that the title of Keator was divested and vested in the plaintiff. In order to establish a prima facie title to personal property, under a sale by the town treasurer, it is not sufficient to show that the treasurer claimed to sell for the nonpayment of a tax, but the purchaser must show that the treasurer had a legal tax warrant in his hands, under which the sale was made, and that such warrant showed ón its face a tax against the person whose property was sold, which he was, by the command of said warrant, required to collect, and that the proper notice of sale was given. Mericle v. Mulks, 1 Wis., 366; Power v. Kindschi, 58 Wis., 539; McLean v. Cook, 23 Wis., 364; Sprague v. Birchard, 1 Wis., 457; secs. 1127, 4162, R. S. 1878.
It must be admitted, therefore, that the plaintiff in this action failed to show even a prima facie title as against the title of Keator. But he did show that he had possession of the property in suit under a claim of title when the defendant took possession of the same. Possession under claim of title is all that is necessary to be shown by the plaintiff in order to recover against a mere trespasser, or one not acting under or by the authority of the real owner. Hutchinson v. Lord, 1 Wis., 286; Rogan v. Perry, 6 Wis., 194; Stanton v. Kirsch, id., 338; Kemp v. Seely, 47 Wis., 678.
As we understand the evidence in this record, it does not show that the defendant was acting for or on behalf of Keator, the former owner of the logs in question, when he took them from the possession of the plaintiff. For anything appearing in this case, Keator, the former owner of the logs in question, may be satisfied that his title was divested by the tax sale, and have fully acquiesced in the same. It is well established in- this state that in an 'action for the conversion of personal property, under a general denial the defendant may show title in himself or in a third *623person under whom he claims title or the right of possession,— Phoenix Mut. Ins. Co. v. Walrath, 53 Wis., 671, 675,— but this rule does not extend to the creditors of a vendor, or other persons in similar situations, who seek to avoid the title of a vendee on the ground of fraud in the sale. Kemp v. Seeley, supra; Norton v. Kearney, 10 Wis., 443; Jones v. Lake, 2 Wis., 210; Adler v. Cole, 12 Wis., 188, 213. As the evidence in this action does not show affirmatively that the defendant was acting on behalf of the former owner of the logs, in removing them from the possession of the plaintiff, it was error to nonsuit the plaintiff.
By the Court.— The judgment of the circuit court is reversed, and the cause remanded for a new trial.
