¶1This is an ordinary schooi-Iand case. There was a sale in 1886, default in 1897, an abandonment of the land, non-payment of taxes, notice of forfeiture in 1899, proper service but a defective return, proper posting, the record marked “canceled,” a lease by the state, inquiry of the county officials by a prospective purchaser in 1905, followed by a resale, actual possession and valuable improvements. Then an assignee of the first certificates sought to reinstate and enforce the rights which originally attended them. There is no feature of the case not covered by the decision in Burgess v. Hixon, 75 Kan. 201, 88 Pac. 1076. The case of Gray v. Zellmer, 66 Kan. 514, 72 Pac. 228, has no bearing upon the controversy, because the plaintiff and his predecessors in interest by their conduct led the defendants to believe they had submitted to a forfeiture of their rights. The pleadings, being in the ordinary statutory *857form for ejectment, permitted the introduction of evidence establishing equitable estoppel. It is not necessary to consider the constitutionality of chapter 373 of the Laws of 1907.
¶2The judgment of the district court is affirmed.
