When the commissioners shall have made their appraisement of the land taken or to be taken, they shall certify the same and file it with the clerk of the chancery court of the county in which the land lies, and if the proceedings be in another county, also with said clerk in the county where the proceedings are had. The clerk shall thereupon set down and fix a time for the hearing of objections to such appraisement, at the request of the commissioners, to be heard by the chancery court or the chancellor in vacation. The clerk shall issue a summons directed to the sheriff of the county or counties of this state in which any landowner or other person interested may reside, commanding him to summon such owner or owners or other interested person to be and appear at the time and place named. If the owner of any land sought to be taken be an infant or person of unsound mind, the summons may be executed on his guardian; and the guardian in such cases is authorized, subject to the approval of the chancellor in term time or vacation, to sell and convey such property and dedicate it thus to the public use, or he may agree upon the damages and thereby bind the ward. If there be no guardian in such case, the chancellor in vacation may, on application of any one in interest, appoint a guardian ad litem to represent such infant or person of unsound mind, whose acts and doings in the premises shall be valid and binding on the ward. The chancellor may require a bond of such guardian ad litem. If the owner of such land be a nonresident of the state or cannot be found, or if the owner be unknown, and this shall apply to any person interested, upon affidavit to that fact being made by the commissioners or by their agent or attorney, service of the summons may be had on any of his agents in charge of the land; or publication shall be made in the manner provided by law for publication for nonresident and unknown parties in chancery suits. If the land belong to a deceased person whose estate is being administered, the summons may be served on the executor or administrator, who shall, for all purposes of this chapter, be authorized to act for the owner, and he shall be responsible on his bond accordingly. Such notice, when published, need only state that the hearing will be for the purpose of confirming the report of the commissioners as to the appraisement of land taken for the use of the district and through which the ditches of the district are to run; it shall contain the names of the owners or persons interested in such land and their post-office address, if known, and if unknown that fact shall be so stated; and it shall further contain a list of the land, described by section numbers, belonging to such nonresident owners and through which the ditches of the district are to run. If any owner is not satisfied with the amount allowed by the commissioners for land taken by reason of the construction of such proposed system according to the plans of said district, he shall file written objections thereto on or before the day named in the summons or notice.
