¶2The first deed shows that the land in controversy was sold by the treasurer at a tax sale, on the first Monday of October, 1863, in separate tracts ,of one hundred and sixty acres each, for the taxes, interest and costs then due and remaining unpaid on each of. said tracts of land respectively ; that each tract was separately bid for by, and struck off to, oneE. E. Erush, who assigned the several certificates of sale to the defendant, who, at the expiration of the term of redemption, no part of the land having been redeemed, demanded and received the treasurer’s deed for the same.
¶3It is insisted in argument for appellant, that, inasmuch as the deed shows that more than forty acres, or the least legal subdivision of land, was sold at one sale, the deed upon its face shows a non-compliance with the requirements of the revenue law, and is therefore null and’void.
¶4This position is fully answered in the case of Corbin v. De Wolf, 25 Iowa, 124, where it is held that land may be sold for taxes in tracts greater than forty acres, when so assessed to known owners; that sections 737 and 745, which require that in cases where the owners of lands are v/nk'fiown, the assessment thereof and the entry of the same in the tax-book shall not exceed the sixteenth part of a section, or smallest subdivision of land according to government survey, is, upon the maxim expressio v/nius exolusio alterius, authority, where the owners a/re Imown, for its assessment in larger tracts.
¶5And the case of Penn v. Clemans, 19 Iowa, 372, which holds, that “the sale of several distinct subdivisions or parcels of land in gross is irregular,” is explained in the opinion delivered by Mr. Justice Beok, thus: “ The word ‘subdivision’ is used to indicate a quantity of land, greater or less, and in its connection is synonymous with the word ‘ tract.’ … Eighty acres, or one hundred and sixty, or three hundred and twenty, when in one body, are sub*464divisions. One subdivision may be sold at a sale, but two cannot; one hundred and sixty acres in one body is one subdivision and, therefore, can be sold at one sale.”
¶6“ The point decided in Penn v. Clemansis, that when these subdivisions are assessed separately, or are, in fact, distinct and separate, as two ‘forties’ in different sections, they cannot be sold in gross.” Corbin v. De Wolf, supra.
¶7If the deed showed that the land had been assessed to ah unknown owner, in tracts greater than forty acres and so sold, it would show a sale in violation of the statute ; but the deed does not so show, and as it is regular and proper, in ease of known owners, to assess lands lying contiguous, in tracts as large as one hundred and sixty acres, and to thus offer the same for sale for the taxes, interest and costs due and unpaid thereon; and when no person offers to pay the amount thus due and unpaid, for a quantity of the land less than the whole tract, the treasurer may lawfully sell the whole tract, it follows that there is no irregularity or illegality apparent upon the face of this deed, but on the contrary it appears that the law in all respects has been complied with, taking the recitals of the deed as true. See Corbin v. De Wolf, supra; Eldridge v. Kuehl, 27 Iowa, 160; Stewart v. Corbin, 25 id. 144; McCready v. Sexton & Son, 29 id. 356; Ware et al. v. Thompson, id. 65.

¶9By section 184 of the Revision, a tax deed executed and acknowledged by the treasurer, in substantial compliance with the requisites of the law, is declared to be conclusive evidence of certain things, and prima facie evidence of *465others. In McCready v. Sexton & Son, 29 Iowa, 356, this court held, that as to the facts of assessment, levy and sale, it was not competent for the legislature to enact that the deed should he conclusive upon the person whose land was sold; that as to these fundamental facts — these essential prerequisites — the deed was not conclusive evidence. It is said, however, in that case, that “ as the time and manner in which they (the assessment, levy and sale, which are the only fundamental steps) shall be done, the discretion of the legislature is absolute and supreme, and cannot be judicially controlled or interfered with. Having the right to prescribe the manner, it may also rightfully provide, that a failure to comply with its directions as to the manner shall not defeat the end, or that no person shall question the manner, or that any subsequent act shall be either prima facie or conclusive evidence that the law, as to the time and manner, was complied with.” And, in Rima v. Cowan et al., 31 Iowa, 125, it was held, by a majority of the court, that although the statute could not make the deed conclusive evidence of the fact of a sale of the land for taxes, it did make it conclusive as to the manner of sale.
¶10Appellant does not question that the lands in dispute were, in fact, assessed; that taxes were levied thereon, and that they were, in fact, sold by the treasurer for the taxes thus levied and remaining due and unpaid. The objections are exclusively as to the manner of the sale. Of this the deed is conclusive evidence, that the sale was conducted in the manner required by law, etc. Rev., § 784; and see McCready v. Sexton & Son, supra; Rima v. Cowan et al. supra; Hubbard v. Board of Supervisors, 20 Iowa, 134; Allen v. Armstrong, 16 id. 508; Eldridge v. Kuehl, supra.

¶12We have seen that the deed first executed by the treasurer is regular on its face and conclusive on the questions made by appellant, and, being recorded, it vested in the defendant “ all the right, title, interest and estate of the former owner in and to the land conveyed,” under section 784 of the Revision. This being so — the treasurer having made a deed to the purchaser in pursuance of the sale-of the land for taxes — the making of the subsequent deed was a mere nullity. The treasurer, when he made and acknowledged a valid deed in accordance with the sale, exhausted his power to make another, and the making of a second deed in such case could have no effect upon the title vested by a prior one. The treasurer has power to. make a second deed only in case of an informal or insufficient execution of the first in substantial compliance with the law and the sale of the land. Harper v. Sexton, 22 Iowa, 442; Finley v. Brown, id. 538; McCready v. Sexton, supra; Thomas v. Stickle et al., ante, 71. When, therefore, the treasurer has exhausted his power by the execution and acknowledgment of a tax deed, formal and regular in all respects, by which the title has become vested in the purchaser, that title cannot be divested or affected in any degree or manner by the execution of a subsequent deed which the treasurer had no power to make; and the question, whether such subsequent deed shows a compliance with the law or not, is immaterial.
¶13Our conclusion upon the whole case is, that the grounds urged by appellant for setting aside defendant’s tax deed and title to the lands in controversy are, under the statute and former decisions of this court, insufficient, and the judgment of the district court must be
¶14Affirmed.
