1. 1. If no person shall redeem the lands sold for taxes within two years from the sale, at the expiration thereof, and on production of certificate of purchase, and in case the certificate covers only a part of a tract or lot of land, then accompanied with a survey or description of such part, made by the county surveyor, the collector of the county in which the sale of such lands took place shall execute to the purchaser, his heirs or assigns, in the name of the state, a conveyance of the real estate so sold, which shall vest in the grantee an absolute estate in fee simple, subject, however, to all claims thereon for unpaid taxes except such unpaid taxes existing at time of the purchase of said lands and the lien for which taxes was inferior to the lien for taxes for which said tract or lot of land was sold.
2. 2. In making such conveyance, when two or more parcels, tracts, or lots of land are sold for the nonpayment of taxes to the same purchaser or purchasers, or the same person or persons shall in any wise become the owner of the certificates thereof, all of such parcels shall be included in one deed.
