The cemetery lots shall be conveyed by certificates, signed by the mayor and countersigned by the clerk, under the seal of the city, specifying that the purchaser to whom the same is issued is the owner of the lot or lots described therein by numbers, as laid down on such map or plat, for the purpose of interment, and such certificates shall vest in the purchaser, his or her heirs and assigns, a right in fee simple to such lot for the sole purpose of interment, under the regulations of the council; and such certificates shall be entitled to be recorded in the office of the recorder of deeds of the proper county without further acknowledgment; and such descriptions of lots shall be deemed and recognized as sufficient description thereof. The council may limit the number of lots to be owned by the same person at the same time, and may prescribe rules for enclosing, adorning and erecting monuments, tombstones and ornaments on cemetery lots, and prohibit any improper adornment thereof; but no religious test shall be made to the ownership of the lots, or burials therein, or for the ornamentation of graves or lots.
