By the Court,

This is an action to recover the possession of an undivided one half interest in a mining claim. Plaintiffs obtained judgment and defendant appeals.

The facts are, that on the first of August, 1867, S. Sever and E. Gregovich located the mining ground in controversy, viz., sis hundred feet in length of tbe George Washington lode, two hundred feet thereof being for á discovery claim; that on the fifteenth of February, 1873, Sever conveyed his interest therein, by deed, to B. Evanovich; that on tbe nineteenth of May, 1874, Evanovich conveyed the same interest to the plaintiffs; that on the twenty-fourth day of September, 1872, Evanovich declared his intention to become a citizefi of the United States, and received his naturalization papers on the eighth of September, 1873; that on the sixth of June, 1876, Sever declared his intention of becoming a citizen, and afterwards, and before the relocation of tbe premises by the defendant Gregovich, he was duly naturalized, and became a citizen of the United States; that on the eighteenth of February, 1880, the defendant Gregovich relocated the mining ground in controversy in his own name, without the consent of plaintiffs, or either of them; that during all the time from the first location of the claim by Sever and Gregovich until the relocation of the premises, as above stated, the work and labor as required by the statutes of the United States, and the laws of Columbus mining district, where said claim is located, were performed by said, parties, and that during all of said time said Evanovich, or said plaintiffs, with the consent and assistance of said defendant, and jointly with him, had tbe said work and labor performed, and that during said time the said Sever and Chiatovich have paid to the said Gregovich various sums of money for his doing their proportionate part of said work and labor.

*327Upon tbe trial, tbe defendant offered to prove that the Yietor mining claim was discovered and located for several years prior to tbe first of August, 1867, and was upon tbe same lode as tbe George Washington claim. Tbe object and purpose of this evidence was to show that tbe locators of tbe George Washington claim were not tbe discoverers of tbe lode.

Appellant, Gregovich, claims that tbe court erred in refusing to admit this testimony, and that Sever, being an alien at tbe time of the first location of tbe claim, bad no right to bold or claim an interest therein, and for these reasons tbe relocation of tbe claim by himself was valid, and tbe respondents have no valid interest or claim to any portion of said mining ground. We are, however, of tbe opinion that tbe judgment of tbe district court is correct.

Appellant is not in a position to take advantage of tbe defects, if any exist, in plaintiff’s title to the ground in dispute. He joined with Sever in claiming two hundred feet of tbe ground as a discovery claim, and afterwards recognized tbe claims of Sever,'Evanovich, and Chiatovich to tbe mining ground, including tbe discovery claim of two hundred feet, as being valid. He accepted from them their proportionate share of tbe money expended for work and labor done upon the entire claim, and for these reasons be was and is estopped, by bis conduct and acts, from denying tbe rights claimed by Sever and Chiatovich as owners therein.

Tbe judgment of tbe district court is affirmed.
