The deed of the treasurer to E. C. Byam was executed December 2, 1863, and recorded January 11,1864. *29The petition in this case was filed on the 27th day of October, 1869, more than five years after the recording of the treasurer’s deed.
This deed, under which the defendant claims, is in the form which has frequently been held by this court to be insufficient to pass any title to the purchaser; and its invalidity is tacitly admitted by appellant.
He relies solely for a reversal of this case upon the fact that the action of plaintiff is barred by section 790 of the Eevision, under the construction adopted in Thomas v. Stickle, 32 Iowa, 71.
At common law a statute of limitations must be pleaded. Stult v. Murphy, Morris, 321.
Section 2961 of the Eevision provides that “ where a pleading shows affirmatively, that its cause of claim is barred by the statute of limitations, it may be assailed by demurrer.” But unless the statute is insisted upon, either by demurrer or in the answer, it is regarded as waived. This is the positive provision of the statute.
Section 2876 of the Eevision prescribes the causes of demurrer, and, as one of them, refers to section 2961, above quoted.
Section 2878 is as follows: “When any of the matters enumerated in section 2876 do not appear on the face of the petition the objection may be taken by an answer. If no such objection is taken either by demurrer or answer, the defendant shall be deemed to have waived the same, except only the objection that the petition does not state facts sufficient to constitute a cause of action, or states a fact which avoids the cause of action.”
That this exception does not include the objection that the claim is barred by the statute is apparent from an examination of section 2876, in which, in addition to the causes contained in the exception, section 2961 is specifically referred to, and recognized as a distinct ground of demurrer.
In this case the answer merely denies the plaintiff’s claim, and avers that the title and right of possession are in defend*30ant. The defendant does not insist upon the statute of limitations, and must be regarded as having waived it. See, 'also, sections 2942 and 2944 of the Revision.
It follows that the judgment of the court below must be
Affirmed.
