¶1delivered the opinion of the court:
¶2This is an action to quiet title to real estate.
¶3The complaint is in the usual form. Two defenses are attempted to be set up in the answer, the first consisting of admissions, and denials only.' The second pleads title in defendant by virtue of a tax deed.
¶4Plaintiff replied denying the validity of the tax deed, and alleging that the proceedings leading up to its execution were defective in several respects, among which was that no sufficient affidavit of publication of the notice of the tax sale had been made.
¶5The cause went to trial and among other things it is shown that the proof of publication recites that copies of each number of the paper in which the notice of tax sale was published were delivered by carrier or transmitted by mail to each of the subscribers of said paper “in the county of Arapahoe,” according to the custom of business in the office of the newspaper.
¶6■ Judgment was rendered for the plaintiff. Defendant appeals.
¶7The questions discussed in the briefs are as to the sufficiency of defendant’s defense, and as to *352■whether or not it .was necessary for the plaintiff to' prove possession in order to maintain the action.
¶8Appellant contends that plaintiff was' not entitled to judgment because the proof does not show that he was in possession of the premises and that his being in possession is a jurisdictional matter.
¶9While plaintiff, to maintain the action, must aver his possession coupled with title, the duty is devolved upon defendant of asserting an adverse interest in himself and specifying its nature, and before he can put plaintiff upon proof touching his possession and the title, he ' must plead accordingly. — Wall v. Magnes, 17 Colo. 476.
¶10Defendant has not done this. The first alleged defense consists merely of denials and admissions. This defense standing alone is not sufficient to put in issue the possession of plaintiff, because, as was said in the case of Wall v. Magnes, supra,before defendant can put plaintiff upon proof touching his possession and title, he must plead an adverse interest in himself.
¶11The defendant may plead as many defenses to the cause of action alleged in plaintiff’s complaint as he desires, but each of these defenses must be complete of itself and must be tested by its own allegations. — Weston v. Estey, 22 Colo. 343; Travelers’ Ins. Co. v. Redfield, 6 C. A. 196.
¶12The first defense neither alleges title nor possession in the defendant.
¶13The second defense of defendant fails because the affidavit containing the proof of publication of the notice of tax sale shows that the paper containing the notice “was delivered by carrier or transmitted by mail to each of the subscribers in the county of Arapahoe, in the state of Colorado.'” The statute requires that this affidavit shall show that copies of each number of the paper were ‘ ‘ delivered by carrier or trans*353mitted by mail to eaeb of tbe subscribers.” It is apparent that the delivery of the papers to each of the subscribers in a single county does not conform to the requirements of the statute.
¶14Unless an affidavit of publication of notice of a tax sale shows that copies of each number of the paper in which tbe notice was published were delivered by carriers or transmitted by mail to each subscriber of tbe -paper, according to tbe custom and mode of business in tbe office, it is insufficient and a sale based thereon is invalid. — Rustin v. M. & M. Tunnel Co., 23 Colo. 351; Morris & Thombs v. St. Louis N. Bk., 17 Colo. 235.
¶15The second defense failing, tbe denial of plaintiff’s possession in the first defense is not sufficient to put plaintiff upon proof touching tbe same.
¶16Perceiving no error in tbe proceedings of tbe court, the judgment will-be affirmed.
¶17Affirmed
